The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 235: Scared to Death
August 21, 1983. Today's surprise was given by the two scientific research teams of Yu Zhengze and Ao Xuanling. They made an indelible contribution to the successful completion of the Xiaolingtong mobile phone project.

In the No. 2 Laboratory Building of Harbin Institute of Technology, when Wang Duoyu arrived, Liu Deben, Lu Gongliang and others were already fiddling with their mobile phones.

The Xiaolingtong mobile phones in their hands are small and exquisite, only the width of three adult fingers, only about one and a half times the length of an average adult's middle finger, and about the same thickness as an adult's thumb.

From such a simple point of view, this Xiaolingtong mobile phone can definitely beat the Motorola 8000X currently on the market.

Because the body of Motorola 8000X, including the antenna, is 13 inches high and weighs two kilograms, it looks very bulky and large, just like a brick.

The PHS mobile phone developed by Harbin Institute of Technology is not as exquisite and compact as the later ones, and weighs only 8000 grams, or kilograms, but even so, it is enough to beat Motorola X.

"Professor Wang, you're here, hurry up."

Seeing Wang Duoyu come in, Yu Zhengze and others greeted him warmly.

Wang Duoyu greeted Liu Deben and others with a smile, then took the Xiaolingtong mobile phone with a face full of emotion.

From the design point of view, this black PHS mobile phone is still very fashionable and avant-garde, but it is indeed a little heavier and much larger.

In the past life, in the era of smartphones, screens became larger and larger, which led to larger and larger phones.

But before the advent of smartphones, many "senior phones" were quite small and exquisite, weighing less than 100 grams and very light.

After sighing for less than a second, Wang Duoyu calmed down and started the test.

What's more, the call quality and signal strength of this Xiaolingtong mobile phone are far superior to previous cordless phones.

It can also be seen from here that in just one or two years, Harbin Institute of Technology has made great progress in communication technology.

Of course, the call quality and signal of this Xiaolingtong mobile phone are still not comparable to the Xiaolingtong of the millennium in the original time and space.

Overall, there is still a lot of room for improvement.

What's more, this Xiaolingtong mobile phone cannot receive and send text messages, let alone receive and send emails, so there is still a lot of room for improvement.

"We have currently installed two base stations on the two tallest buildings on campus. The signal strength is a little weaker than in the lab, but it definitely exceeds the 500-meter signal range."

During the test, Ao Xuanling explained:

"We prepared ten PHS phones for comprehensive testing, including multiple test items. Judging from the results so far, everything is going very well."

"We haven't tested it in extreme weather conditions yet, but we're about to enter winter, so we'll be able to test it then."

The Xiaolingtong mobile phone is the most important scientific research project of their two departments, the Department of Information and Communication Engineering and the Department of Electronic Science and Technology, and is also a key battle that determines the status of their two departments in Harbin Institute of Technology.

Therefore, both Ao Xuanling and Yu Zhengze were very serious and responsible, and each led their team to overcome technical difficulties.

The project was launched in August 101 and was then a top-secret project code-named .

It has been two years now. It seems like a short time, but it is actually quite long.

Moreover, this Xiaolingtong mobile phone has not been completely completed yet and cannot be directly put into the production line, but the construction of base stations can be advanced.

Therefore, relevant cooperation can be discussed in advance.

Wang Duoyu spent half a day getting to know this Xiaolingtong phone, and after confirming that its technical research and development had reached completion, he said:

"Secretary, Project 101 can be concluded, and we can start preparing for the launch of the Xiaolingtong mobile phone."

"When we were in the United States, we established very good cooperative relationships with those telecom operators. This time we can invite them to come to our Ice City to discuss cooperation."

It will take at least half a year for the Xiaolingtong mobile phone to be put on the market, because base stations need to be built, which is a huge investment.

Moreover, the base station of Xiaolingtong mobile phone is completely different from the base station of Motorola 8000X.

It's just because the base station of the Xiaolingtong mobile phone uses micro-cellular technology, the signal of this technology is only 500 meters, because it is an amplified version of the cordless phone, that's all.

But it doesn't mean that the technology of Xiaolingtong mobile phone is very low-end. On the contrary, its technology is still quite difficult.

What's more, the patent has already been applied for by Huaxin Company, so how could it be possible for others to find loopholes?
After all, the Xiaolingtong mobile phone is not a GT316 solid-state drive based on logic gate circuit flash memory technology, so it does not need to be kept confidential.

The GT316 solid-state drive has been developed for more than a year, but it is still not on the market because Toshiba is still busy with the lawsuit. Anyway, Wang Duoyu is not in a hurry.

Base stations with a 500-meter signal range are only suitable for construction in densely populated areas, such as cities, especially large cities.

Major American cities such as New York, Los Angeles, and Chicago will definitely need to build a large number of base stations, and several base stations will need to be built within every 500 meters.

This cannot be achieved by simply referring to the cellular model for construction, because there are many tall buildings in the city and any wall may become an obstacle to the signal.

Therefore, it is definitely not possible to just build one base station within a radius of 500 meters.

For example, in a place like Manhattan, there are many buildings that are more than 400 meters high. If only a base station is built on the top of the building, how can consumers with PHS phones make and receive calls in the underground parking lot of the building or even in the subway underground?

On the other hand, such places are bound to have a large concentration of people. Once there are many people at the same time, such as during rush hours, there may be hundreds or thousands of PHS phones answering and making calls at the same time, which will inevitably cause congestion in the signal channel, thus affecting consumers' experience of making and receiving calls.

These are all factors that need to be considered comprehensively.

Therefore, Xiaolingtong mobile phones definitely cannot directly borrow the signal base stations built before Motorola 8000X. It may be able to borrow some of them, but definitely not more.

Because from the very beginning, the Xiaolingtong mobile phone and the Motorola 8000X were not products of the same level.

From a technical perspective, the Motorola 8000X may be more powerful, but there is no technical superiority or inferiority. We can only say that the signal range of the 8000X is wider, probably covering a few kilometers, which is much wider than the -meter range of the microcellular technology of the Xiaolingtong mobile phone.

Of course, it is impossible for Motorola 8000X to build a base station in a sparsely populated mountain range. Otherwise, they would not have developed a GPS locator for emergency rescue.

In other words, Motorola 8000X is not actually capable of making and receiving calls within all ranges.

Therefore, if Xiaolingtong mobile phones want to be listed on the market, they need to negotiate with relevant operators on how to invest in base station construction, how to distribute profits, etc.

"Okay, let's discuss it first, and then have Professor Shang and the others notify the US side."

Liu Deben nodded and said after hearing this.

This matter needs to be handled by Huaxin Company. Chen Baoxi is not the general manager of Huaxin Company, he is the person in charge of cordless telephones.

So, Wang Duoyu went to the office next door with Liu Deben and others and sat down to talk about this matter.

"Professor Lu, how many sets of base station equipment have Huaxin's factories produced so far?"

As soon as he sat down, Wang Duoyu asked about Lu Jianwei, the current head of Huaxin Company.

The base station equipment for Xiaolingtong mobile phones includes antennas and base station controllers. The technology is relatively simple and was tested in the second half of last year.

It was handed over to the factory for debugging in the first half of this year and then started production.

This is because the base stations must be installed first before the launch of the Xiaolingtong mobile phone can be started.

The latter answered honestly, "We already have 180,000 sets of base station equipment in our warehouse, but our factory is running out of funds."

The antenna contains precious metals such as gold and silver, while the base station controller also contains precious metals such as palladium and platinum. These two devices can be said to be the most expensive devices in the PHS base station.

Therefore, the investment in producing such products is not small.

Upon hearing this, Wang Duoyu couldn't help but frown and looked at Han Jue, "Old Han, why didn't you approve the money for Huaxin Company?"

Although the Enterprise Management Office has just been established, the current actual person in charge is Han Jue, the executive vice president of Harbin Institute of Technology.

What's more, Han Jue was in charge of this area before, so if you want to ask about money, you can ask Han Jue directly.

"Duoyu, this isn't my fault. The school doesn't have much money on hand right now, and several parts of the fund can't be touched. This is reserved for your projects."

Han Jue heard it and quickly explained:
"Besides, there's no rush for base station production. Once the next round of funding arrives, I'll definitely prioritize allocating it to them."

Hearing this, Wang Duoyu nodded slightly and did not ask any further questions, nor did he say that he would hand over the funds to Huaxin Company for use first.

Because some funds are guarantees, if they are told not to be moved, they definitely cannot be moved.

Upon hearing this, Lu Jianwei didn't dare to say anything more, because he knew very well who had the final say in Harbin Institute of Technology.

Not to mention that a higher-ranking official can crush someone to death, even Wang Duoyu's status is not something that a mere person in charge like him can shake.

"That's it, then. You can take your time, but Old Han, you also need to urge the Foreign Exchange Department to transfer the money as soon as possible. If we don't have the money and delay our plans, it will be easy for something to go wrong."

After Wang Duoyu finished speaking, Han Jue nodded in agreement.

This matter ends here. Next, we will formally discuss the pricing of base station equipment, cooperation plans, etc., as well as rehearse negotiations with US telecom operators.

One day passed like this.

The next day, Wang Duoyu no longer participated in the matter of the Xiaolingtong mobile phone.

Harbin Institute of Technology has recruited so many talents. After the overall strategic guidelines are determined, an executive person is needed to implement them and promote the follow-up work of the entire project.

Two days passed in the blink of an eye. On August 24th, Wang Duoyu was in the Nebula Supercomputing Project Office in Laboratory Building No. 6, testing the operating speed of the supercomputer in front of him.

After more than half a year of hard work, Wang Duoyu finally completed a small part of the supercomputing system.

Because it is not a complete version, he can only conduct a simple test.

The technology used in the Nebula supercomputing project is large-scale parallel processing technology, so after obtaining enough processors, it is understandable that he first tests the computer's operating speed and other conditions.

Song Xinwen, Pang Dianchen, He Jiasheng and others were all at their respective posts, anxiously looking forward to the upcoming test.

All the processor components of the supercomputer have been checked repeatedly. After confirmation, Wang Duoyu asked Lu Xuemin to contact the power plant to confirm again that there is no problem with their power supply system.

"Professor Wang, we've confirmed that there are no issues with the power plant. They can ensure there will be no problems with the power supply going forward."

After making a phone call to confirm, Lu Xuemin immediately reported to Wang Duoyu.

Since it is a supercomputer, even if it is not a complete version of the computer, but with so many processors, cooling fans, etc. started up at the same time, its power consumption will be terrifying.

The entire Harbin Institute of Technology is not just about the Nebula supercomputer project, so for this test, Wang Duoyu applied for a separate power supply line from the power plant.

In addition, there are regular circuits and backup circuits, with a total of three power supply lines to ensure the normal operation of the Nebula supercomputer.

"Okay, everyone, be alert and let's start the test."

Upon hearing this, Wang Duoyu immediately spoke loudly.

Pang Dianchen and others nodded seriously, and then stared at the work in front of them seriously.

Under Wang Duoyu's command, Song Xinwen started the Nebula supercomputer.

As the power button is pressed, the entire computer starts running, the machine makes a slight noise, and the cooling fan starts working synchronously.

The entire laboratory also entered the most tense state.

"Report, the equipment on Team One's side is currently operating normally."

"Report, Team Two, everything is normal. No abnormalities found in the equipment. Report completed!"

"Report, Team 3"

Wang Duoyu, who was in the middle, listened to the work reports of each group and nodded slightly.

If the equipment is operating normally, then we can start testing various data.

Wang Duoyu is certainly very experienced in testing supercomputers. He has even prepared multiple sets of different data that need to be calculated.

The conventional method of testing supercomputers is to evaluate the speed of supercomputers by using their ability to solve linear algebraic equations.

As a mathematics professor, Wang Duoyu is no exception, but the linear algebraic equations he uses are only more complex and more able to fit the speed performance limit of the current supercomputer for testing.

As for whether this would cause the computer to lose control or crash, Wang Duoyu was not worried at all.

Because this is one of the purposes of the experiment. It is impossible that after it is built and turned into a product and sold to others, such technical problems will arise later, right?

If there is a problem, you need to find the cause and then solve the problem.

This conventional testing method is actually very simple. During the test, the supercomputer needs to run a specific matrix multiplication calculation program and measure its execution time to determine the calculation speed.

As time passed, Pang Dianchen soon reported the results, his voice trembling:

"Professor, the first test data is out. The current floating-point computing speed of this supercomputer is 3.28 billion operations per second."

Inside the laboratory, everyone fell silent, though their eyes were still fixed on the equipment in front of them to ensure that it was functioning well.

But in fact, they all pricked up their ears.

The speed is 3.28 billion times per second. This is what Wang Duoyu said before the experiment began, but no one thought it could really be achieved.

Because before the experiment, it was just Wang Duoyu's "precise calculation". Although everyone was willing to believe it, it was ultimately just a prediction.

Now it's become a reality, and that's why everyone is excited.

However, no one cheered, just the corners of their mouths curled up slightly, indicating that they were in a very good mood.

"Keep testing!"

Upon hearing this, Wang Duoyu calmly gave the order.

In addition to the conventional testing method of linear equations mentioned above, supercomputer testing also includes high-performance benchmark testing, standard performance evaluation testing, and memory bandwidth performance testing.

High-performance benchmarks measure the performance of computer systems under different workloads, covering high-performance computing, fast memory bandwidth, global collective operations, and latency and bandwidth of communication modes with increased complexity between multiple nodes.

Without mentioning the standard performance evaluation test, Wang Duoyu attaches great importance to the memory bandwidth performance test that is currently being carried out.

The so-called memory bandwidth performance test is actually used to evaluate the performance of a supercomputer's memory system. During the test, a specific memory bandwidth test program needs to be run, which requires professional testers and test tools to complete.

Therefore, the entire testing process is very critical.

There is no room for carelessness.

As the most advanced product in China's computer technology, the Nebula supercomputer has the ability to efficiently process large-scale data and complex computing tasks.

Once it is successfully developed, the Galaxy giant supercomputer that has not yet been developed by the National University of Defense Technology in Changsha will be completely useless.

In fact, a few years ago, when Wang Duoyu took out the distributed computer with a speed of 80 million floating-point operations per second, the Ci Yungui team of the Galaxy supercomputer at the National University of Defense Technology was already very nervous.

Three years later, Ci Yungui's team has not yet completed the development of the Galaxy giant supercomputer, but Wang Duoyu is about to come up with a supercomputer with a floating-point computing speed of more than 3 billion per second. I really don't know what their expressions will be when they know this news.

"Each team, report the current situation!"

As time passed, after completing three tests, Wang Duoyu asked the teams from each department to report on the situation.

After getting the accurate answer, Wang Duoyu nodded.

"Excellent, very good. Everyone has done a great job. I declare that the scientific research tasks of our Nebula Supercomputing Project have come to a temporary end."

"Based on our current test results, there is absolutely no problem with the architectural technology direction I proposed earlier." "I'll give you all five days to rest. After five days, everyone will return to their posts. At that time, we will directly launch an attack on the exaflop supercomputer."

"I hope everyone doesn't fall behind. There will be bonuses and other things, and don't think I forgot."

yeah!
Following Wang Duoyu's voice, everyone cheered.

Song Xinwen, Pang Dianchen, Niu Xisheng and others were very happy. After they cheered, Wang Duoyu clapped his hands and asked everyone to calm down.

"Okay, there are still some tests to follow. Lao Song and Lao Pang, you two will keep an eye on it for me. If you have any questions, feel free to come to me."

"Okay, professor, we got it."

Wang Duoyu nodded, turned and left.

He still had things to do, and he was going to the capital tomorrow. There was still a lot to do, so he had to leave first.

That evening, when Wang Duoyu was about to go home for dinner, Song Xinwen and Pang Dianchen came to his office and blocked him.

Seeing the two of them coming, Wang Duoyu just stood up, but had to sit back down.

This stool had already endured his oppression for an entire afternoon and should have been able to rest, but now it had to continue to be oppressed by Wang Duoyu.

"Professor, we have completed all the tests, and the Nebula supercomputer has now passed the test completely."

"Yes, Professor. We have developed a supercomputer capable of running 3.28 billion floating-point operations per second. We are the best in China and have reached the international leading level."

In the first half of this year, the Polar Bear Empire had reported in newspapers that they had developed an M13 computer with a floating-point computing speed of one billion times per second.

When this news came out, it shocked many people because the Polar Bear Empire's technology in large-scale integrated computers was actually lagging behind the international level.

However, no one expected that after Cray successfully launched the Cray X-MP/2 parallel vector computer last year, the Polar Bear Empire also successfully reached this level in the second year.

how to say?

Awesome!
However, no matter how awesome it is, Harbin Institute of Technology, with the help of Wang Duoyu, the Emperor of Mathematics, has successfully broken through the supercomputer to the top level of 3.28 billion floating-point operations per second using large-scale parallel processing technology.

However, compared to the surprise of Song Xinwen and Pang Dianchen, Wang Duoyu was exceptionally calm.

It's simply because he is too aware of the current advantages of Harbin Institute of Technology and the power of large-scale parallel processing technology.

If it simply follows Cray's old path, it will undoubtedly fail.

Because in May of this year, CBS President Fred Stanton agreed to Sirius simply because of a very creative idea proposed by the latter: parallel algorithm!
During his graduate studies, Sirius designed a massively parallel processing computer with 6400 processors, also called a connection machine, to replace the traditional von Neumann architecture computer.

This is a very non-mainstream approach, and naturally it will not be recognized by the mainstream, especially by Seymour Cray, the founder of today's supercomputer giant Cray.

Since Wang Duoyu knew this, he entered this industry one step ahead.

Of course, this is also because Harbin Institute of Technology already has such technical reserves. Otherwise, even if he had the idea, he would not be able to do it.

After all, he had completed the development of distributed computers in the mid-1980s, so there was no reason for him to delay proposing the Nebula supercomputing plan until last year's summary meeting.

Sirius had already received $1600 million in angel investment, and after getting the funds, he immediately found Sydney Handler, who was studying for a doctorate at the Massachusetts Institute of Technology. The two went to Massachusetts together to establish Thinking Machines, which mainly used parallel mechanisms to develop supercomputer connection machines.

Moreover, Cialis's technical team is very luxurious. In addition to himself and Sydney Handler, the vice president is Richard Clinton, the creation scientist Marvin Minsky, the product development director Marvin Denikov, the chief engineer Brister Kahler and others.

Most importantly, almost all members of their technical team come from universities such as MIT and Stanford University.

In addition, they even have a famous French chef, which is super luxurious.

In fact, Wang Duoyu is also very clear that according to the historical development trajectory of the original time and space, Thinking Machine Company is about to reach their peak.

Because behind this luxurious team, there are many world-class scientists serving as technical advisors, such as mathematician Eric Lander, who has studied the application of combinatorics and representation theory in coding theory.

There is also Stephen Wolfram, a computer scientist and mathematician, Sydney Brenner, a future Nobel laureate, and Richard Feynman, who won the Nobel Prize in 1965.

However, in this time and space, Wang Duoyu will definitely not let them get ahead.

"Okay, I understand. You should keep this supercomputer and place orders with the lithography machine factory and other units, urging them to complete the production of other processors as soon as possible."

After a pause, Wang Duoyu continued:

"Let's take advantage of this opportunity to build a few supercomputers to help our project department recover."

The total investment in the Nebula supercomputing project is 500 million RMB, which is actually enough no matter what.

But Wang Duoyu just wanted to make the most of the products instead of coming up with the best products right away.

If we can upgrade a few more generations of supercomputers, we can make more money.

You know, the price of Cray1 is as high as million US dollars per unit. Wang Duoyu is also drooling over such a product price.

Last year, Cray launched its latest product, the Cray X-MP/48, which costs as much as $1200 million.

Wow, the San Diego Supercomputer Center in California, USA, directly ordered two machines, and other scientific research institutions also placed orders. As a result, Cray's revenue quickly exceeded one billion US dollars, making it a super profitable supercomputing company. Even IBM had to temporarily avoid it.

The Nebula supercomputer designed by Wang Duoyu, with relatively cheap labor and scientific research costs in China, takes the current supercomputer with 80,000 processors as an example, the equipment cost alone will definitely not exceed 10 million yuan.

Of course, the more you sell, the lower the cost.

If more than 100 units can be sold, the cost of the Nebula supercomputer, which currently has a floating-point computing speed of 3.28 billion times per second, can definitely be reduced to RMB 2 million per unit.

So, when we sell it to those foreigners, we can directly sell it at the price of 4.99 million US dollars. It should be very competitive, right?
As for the situation where a film is well received but not commercially successful, Wang Duoyu absolutely does not believe it.

If not many people are willing to buy it for $4.99 million, what about $2.99 ​​million?

So he was not worried about such a thing happening.

However, these are just thoughts for now, and we still need to deal with the technical and production issues in the future.

"So, our current team of 158 people is not enough, and we need to recruit more technicians."

After hearing Wang Duoyu's overall plan, Song Xinwen and Pang Dianchen were very excited. If this matter could really be implemented, there would be no doubt that the Nebula supercomputer would be able to make a profit.

"Okay, professor, we promise to complete the task!"

Wang Duoyu nodded, stood up, patted their shoulders, and said earnestly:

"The next six months will be the busiest time. You'll not only need to focus on R&D, but also production, so you must take good care of your health."

The production of supercomputers is definitely different from that of other products, and the R&D team must also be the production team, because this part of the technology is difficult to be directly handed over to the production team to complete.

So this requires the R&D team to keep an eye on it at all times.

"Please rest assured, Professor. We will take good care of our health and will not let any problems arise with the project."

"I believe you."

The next day, Wang Duoyu arrived at Yanjiagang Airport and set off for Beijing.

Originally, he didn't want to bring the little guy Wang Junhong this time, but the little guy was crying loudly and no one could persuade him.

"Be obedient. If you don't obey, I will never take you on a plane again next time."

Wang Duoyu shouted sternly, but the little guy was still crying, but he didn't cry out loud. Instead, he opened his arms pitifully and asked for a hug.

"Okay, I'm just on a business trip for a few days. You have to be obedient at home. Do you understand?"

"Dad, I don't want to. I want to go on a plane with you."

He was on a business trip, not for pleasure, and he didn't have time to take care of the little one.

Zhu Ling, who was standing nearby, suddenly said, "How about I help you take care of him?"

"No need!" Wang Duoyu glanced at Zhu Ling, then gave Liu Xiaoli a look, then turned and left.

Last night, he told Liu Xiaoli to be more careful at home, especially when Zhu Ling came, she should be more cautious.

Although Zhu Ling said that she would not act stupidly, who knows what she would do?
Why can't we use other means, such as using a knife to kill someone, as long as they can remove suspicion from ourselves?

"Dad, woo woo"

The little guy was held in Liang Xiufen's arms, crying very loudly and miserably, as if the whole world had abandoned him.

Wang Duoyu got into the car and asked the security staff to drive a few dozen meters. He looked back and saw the little guy crying and struggling, which moved him.

Ugh!
After thinking for a while, he finally couldn't help it and asked the security staff to help him turn around.

The child is only two years old, not really that old, there is no need to reject him at this time.

"boarding!"

After the car turned around, Wang Duoyu got out and said to Liang Xiufen:
"Xiufen, come with me to Beijing. Xiaoli, you stay here. I'll ask Xiaomin or my eighth sister to come over and help for a few days."

Liu Xiaoli did not think that this arrangement was inappropriate. After all, she had been ill for several months and was not suitable to go out frequently.

Liang Xiufen nodded repeatedly, followed the little guy, and soon got into the car.

The little kid was very happy, dancing in the car, so excited that he almost lost his mind. However, the traces of tears on his face were particularly obvious, forming a sharp contrast with his smile, which made him look particularly festive.

There is no need to pack your personal clothes, as there are already spare clothes left in the capital, so there is no need to bring any extra clothes.

As for other things to eat and drink, there is no need to say more.

After Wang Duoyu made the arrangements, he was about to get back into the car, but Zhu Ling stopped him:
"I want to see my son too. You have to take me with you."

Wang Duoyu was not very happy with the tone. If the tone was a little softer, he would have helped.

"Without!"

But at this time, Zhu Ling got into the car first, and then the little guy immediately rushed over and hugged his mother.

Wang Duoyu: “.”

The car left the Harbin Institute of Technology campus. When passing by Want Want Group, Wang Duoyu asked someone to help notify Wang Yumin and others. After all, Wang Meihe, Wang Meili and others still needed someone to help take care of them. Liu Xiaoli couldn't serve them both alone, right?

The plane took off from Yanjiagang Airport and arrived safely at Nanyuan Airport a few hours later.

Along the way, Zhu Ling wanted to get closer to Wang Duoyu, but the latter kept reading a book or writing something in his notebook with an expressionless face.

Zhu Ling couldn't understand what he wrote at all, because those were all mathematical formulas, just like ghost drawings. How could she possibly understand them?
So her efforts were doomed to be in vain.

After getting off the plane, someone came to pick him up.

"Professor Wang, thank you so much!"

When Yan Jici saw Wang Duoyu appear, a smile appeared on his old face.

The latter was surprised: "Principal Yan, why did you come here in person? You are a senior..."

Wang Duoyu was not only flattered, but also a little frightened.

Although he had made great achievements and was very famous in the field of mathematics, to be honest, he felt that he was not worthy of having an 82-year-old principal personally rush to the airport to greet him.

Not to mention Yan Jici's reputation in the Chinese scientific community, just the fact that he is an 82-year-old octogenarian makes Wang Duoyu respect him very much.

"I'm only in good health now. I'm afraid that in a few years, I won't be able to come to the airport to greet you." Yan Jici said with a kind smile and enthusiasm:

"I was very happy that you agreed to come visit our University of Science and Technology of China last month. I just came to greet you and think of it as a bit of exercise, hahahaha."

Yan Jici, who calls himself old, does not have any problems. After all, he was born in 1901, a typical post-00s generation, but he is in very good spirits and does not look like an octogenarian.

In addition to Yan Jici, Peking University and Tsinghua University also sent several heavyweight leaders to welcome Wang Duoyu.

Although Wang Duoyu's Harbin Institute of Technology is not on the same level as Tsinghua University and Peking University, due respect should still be shown. Moreover, Wang Duoyu is now going to their school to give a speech, so this face-saving project must be reasonable, right?
Zhu Ling, who was holding the little guy Wang Junhong, looked at Wang Duoyu who was surrounded by the crowd with complicated eyes, and a hint of bitterness appeared at the corner of her mouth.

In fact, she didn't regret it at all, but for some reason, she felt uncomfortable.

What happened to her before? Why did she become obsessed?
Such a good man, why do you have to lose him?

These people in front of us may seem to be old men, but in fact, each of them is a leading figure in China's domestic scientific community.

Zhu Ling grew up in Beijing Institute of Technology. Through the influence of her surroundings, she got to know some of the big names in the scientific community.

After all, people like Yan Jici could occasionally appear in newspapers, especially in the 1950s and 1960s.

Wang Duoyu didn't know what Zhu Ling was thinking. After a brief greeting with Yan Jici and the others, he was invited into the car.

He went directly to the Graduate School of USTC, while Zhu Ling and the others were sent back to No. 87, Zhongguancun West Street.

After having lunch at USTC, Wang Duoyu started his so-called speech in the afternoon.

To be honest, he didn't really like such speeches because they were useless.

It's like shouting slogans. It's very exciting at the moment, but after a few days, it will still be the same. What's the use?

The next day, Wang Duoyu went to Peking University and Tsinghua University again, staying there for a few hours respectively before finishing his speech.

But after the speech, it does not mean that his business trip is over, because he still has other work to do.

The main task is to promote the Mach 5 fighter project, and Wang Duoyu is the absolute chief technical expert of the project.

Although he doesn't understand these technologies in many aspects of material research, it doesn't matter, as long as someone else does.

What he needs to do is to coordinate all of this and finalize the technical work of the overall project.

If the project goes astray, he has to correct it in time.

That evening, Wang Duoyu was busy until after eleven o'clock in the evening before he finally returned to his home in Yard 87.

At this time, the little guy Wang Junhong had already fallen asleep, but Liang Xiufen was still awake.

"Uncle Jiu, Junhong has fallen asleep."

Seeing this, he went back to his room to see his son.

But he didn't notice that Liang Xiufen behind him wanted to say something but hesitated. In the end, she didn't say it and turned back to her room to sleep.

Wang Duoyu walked into the bedroom and his eyes fell on the small bed. The little guy was sleeping soundly, but he didn't notice at all that there was a person lying under the thin sheet inside the big bed.

He had been out since seven in the morning and had been busy until now, working for more than fifteen hours. He was so sleepy that he certainly didn't pay attention to anything else.

After seeing the child, he didn't even take a shower. He just lay down and fell asleep in a second.

The next morning, when Wang Duoyu saw Zhu Ling hugging him, he was so scared that he lost his soul.
