You promised to build cars, so why did you go into the military industry?

In May 2012, Zhang Chengyuan returned with his team.

After being away from the base for two years, I stepped onto the land of Gaolu Town again. The scenery in front of me was completely different from the scene in my memory. The solar photovoltaic panels on the roof of the building were really eye-catching.

Faced with Zhang Chengyuan's sudden appearance in front of him, Li Ran was somewhat surprised, but this was followed by delight:

"Is it done with ultra-carbon materials?"

"It's done." Noticing Li Ran's surprised expression, Zhang Chengyuan nodded. "Judging from your completely clueless look, um... what was the mission objective?"

"Construct and put into operation ultra-carbon generator sets with a power output of 50 megawatts or more." Li Ran flipped through the task list.

Upon hearing this, Zhang Chengyuan took a deep breath:

"You really think highly of us... The 5-megawatt test unit was only officially put into operation in March."

"A tenfold difference..."

Li Ran was somewhat frustrated, wondering when this task would be completed. The reward seemed like a carrot hanging in front of him, something he probably wouldn't be able to eat anytime soon.

"Oh, right." Zhang Chengyuan remembered something, "At the end of last year, when we were building the experimental unit, Professor Ma, who works on the artificial synthesis of starch from carbon dioxide, came to visit."

"But we're taking different approaches. To put it simply, we're utilizing the physical properties of carbon dioxide, while Professor Ma is conducting a chemical reaction." Zhang Chengyuan shrugged. "Perhaps his research has run into some difficulties, so he came here to investigate, hoping to find some inspiration by analogy."

Noticing Li Ran's hesitant expression, Zhang Chengyuan asked:

"Can it work?"

"It can be done! But I do know one thing: this technology has a huge energy requirement."

"That makes sense, since it bypasses the biological pathway of plant photosynthesis."

"Alright, now that you're back, take a break." Li Ran was about to end the report. "The company's finances have been doing quite well recently. While you're resting, you can think about whether there are any research directions that interest you."

"No need for that trouble. I have to lead the team out in a week." Zhang Chengyuan waved his hand. "Has Old Wang and the others come up with anything good lately?"

"So rushed? The equipment's already been developed! Where are you going?"

Zhang Chengyuan remained silent.

Li Ran pondered the advantages of the super carbon generator, especially its size, which is only half that of a steam generator, yet its power generation efficiency is increased by 85%, and its net power generation efficiency is increased by more than 50%.

These high-power, miniaturized generator sets are generally used in situations where space is strictly limited...

Could it be... the Liaodong Peninsula, Bincheng Port, shipping...?

No wonder Zhang Chengyuan wanted to keep it a secret.

But logically speaking, shouldn't he have led the team directly to their destination?

How could you come back? Aren't you afraid of leaking secrets?

However, considering that the purchase caused a worldwide uproar, and that the port was opened to the public for a year after its arrival, it is still a significant event.

Moreover, based on history, it will be officially delivered in four months.

A mixture of truth and falsehood, reality and illusion.

Li Ran couldn't understand it.

If he couldn't figure it out, he stopped thinking about it and changed the subject:

"Hmm... it seems like I haven't come up with anything lately."

He stretched out his fingers and began to calculate:

"Solar photovoltaic panels with a photoelectric conversion rate of 40%, 126KW fast charging, the development of the new Lingyun car, chips, rocket engines..."

"A chip? A rocket?!"

Five minutes later, Zhang Chengyuan, wearing a dustproof suit, looked through the glass at Wang Bing and the others who were working.

Looking at the towering gantry and the dismantled lithography machine above them, Zhang Chengyuan finally believed Li Ran's words.

However, Zhang Chengyuan was puzzled. Why disassemble such a perfectly good machine? And why use a gantry frame? That's too crude.

Noticing that he didn't know the person in charge of the project, Zhang Chengyuan didn't intend to go up and talk to him.

After half an hour, the high-performance projection lens, weighing several hundred kilograms, was installed in place with the assistance of several engineers and a gantry crane.

Then, a group of people stepped forward and began the detailed testing work.

In the afternoon, with the seed laser, which was several meters long, successfully reinstalled and debugged, Wang Bing and his team finished their day's work.

Zhang Chengyuan stood outside silently watching all day.

The next day, Zhang Chengyuan found Lin Yu drawing in the research room.

Zhang Chengyuan looked enviously at the Long March 3C rocket model on Lin Yu's desk.

"Hey? Old Zhang, you're back." Lin Yu, who was rubbing his neck, saw Zhang Chengyuan and greeted him happily.

"Okay, I'll come back and rest for a few days. You go about your business, I'll just take a look around."

"Are you still leaving?"

Seeing Zhang Chengyuan nod, Lin Yu didn't ask any further questions and said:

"Let's all get together tonight."

"it is good."

Five days later, in the early morning, Zhang Chengyuan led his team to their destination.

Li Ran, who was in the dormitory, listened to the sound of the car engine, opened a can of beer, and silently saw Zhang Chengyuan and the others off.

In August, Shen Zijie reported to Li Ran that the upgrade of the two lithography machines had been officially completed.

At the same time, a 12-inch tablet, only 1.3 centimeters thick, was placed in front of Li Ran.

Inside the lab, Li Ran excitedly manipulated the tablet in his hand:

"Will this thing work well when installed in the car?"

"It works, but it is limited by performance, and in order to ensure driving safety, the ability of users to install third-party software is restricted."

After all, our self-developed 45nm process CPU is only slightly more powerful than the i7-920 from 09.

Therefore, the quantity used has increased considerably.

"Hmm, it's good that there are restrictions. How's the system? How's it doing?"

"The initial version of the system is almost finished, especially the functions that are closely related to the vehicle system. However, there are still some issues with cross-platform compatibility."

Moreover, we often encounter some inexplicable bugs when developing applications on Android and iOS.

Furthermore, the response delay is too long, which can easily lead to danger when using remote-controlled cars.

I considered Bluetooth direct connection, but not all mobile phones on the market support Bluetooth.

Moreover, some mobile phone Bluetooth components, well, let's just say they're just for show; they might break down from two meters away.

So adjustments are still needed.

Li Ran put down the tablet:

"Regardless of the connection, the speed is limited to below 5km/h, and the brakes will be applied if the signal is lost; also, operation is prohibited if the slope is too steep or the ground is uneven."

It's not wrong to strive for perfection, but given the current objective conditions, we still have to make some trade-offs.

The onboard detector signal has higher priority than the remote control signal to avoid collision accidents.

These issues can be resolved by July next year; there's still plenty of time.

On his way back to the office, Li Ran pondered the progress of the new car's intelligent features.

As soon as Li Ran entered the office, he said to Guo Shuyan:

"Please post a notice on our official website stating that our new model is expected to be released around August 2013. In order to avoid losses for our users, we have carefully decided to, in principle, cease sales of the Lingyun SU7 at midnight on December 1, 2012."

Of course, if someone really wants to buy, we won't stop them. For customers with such a strong desire to purchase a car, the 4S dealership sales staff should explain the pros and cons and focus on persuasion.

"Make a careful decision?" Guo Shuyan looked at Li Ran with annoyance. "When did you make that decision?"

"Three minutes ago. Send it."
