The Grandmother in the Siheyuan

Chapter 399 Changing the World
Ma Shan somehow found out that Liu Hua was still conducting in-depth research on metal 3D printers. He knew that Liu Hua and Tsinghua University had recently opened a company that produced 3D printers, and the business was quite good, especially popular with jewelry companies and dentists.

Ma Shan knew Liu Hua quite well. He knew that Liu Hua was generally not responsible for product upgrades and improvements. Once a product was launched on the market, the remaining tasks were all handled by the engineers of the manufacturing company.

This time, Liu Hua is also researching 3D printers, which reveals something different.

He had always felt that Liu Hua was extraordinary, and he believed that Liu Hua must have made great achievements in the military industry.

So he took advantage of the holiday to go and sound out Liu Hua.

"I heard you're free of any trouble now."

Liu Hua said with a smile, "You've done a good job with intelligence work. You shouldn't be in the Air Force; you should be working in a relevant department."

"Aren't you kidding me? If you can't gather intelligence, what's the point of fighting? Know yourself and know your enemy, and you will never be defeated."

"You're quite something, kid," Liu Hua said with a smile. "Have you already planted an intelligence agent next to me? Otherwise, how would you know the enemy and yourself?"

Ma Shan quickly waved his hand: "That's impossible. Your security clearance is higher than mine. I just asked your school's academic committee, and they said you're researching metal 3D printers."

"Haven't you already found out everything? Why are you asking me again?"

Ma Shan frowned and carefully considered his words: "As you know, although I often deal with scientists like you, I am essentially a roughneck."

Liu Hua laughed and said, "A roughneck? You're a military academy graduate, after all. In this new era, what soldier is just a simple-minded roughneck?"

“Compared to you guys, I’m just a complete bumpkin,” Ma Shan emphasized. “What’s this metal 3D printer used for?”

"So what exactly is a 3D printer used for?"

“We can print out several models together, and the computer control is very precise,” Ma Shan said with a smile. “I’ve seen other scientists use your company’s products, and I’ve also helped some research institutes with their procurement before.”

Liu Hua spread his hands: "Isn't that settled? Metal 3D printers, as the name suggests, use metal powder as raw material, such as powders of special metals."

Ma Shan's eyes darted around: "If that's the case, then metal 3D printers can replace high-precision machine tools. Some of our parts are just not precise enough, which is why we can't catch up with the West."

Liu Hua shook his head: "Don't dream about it. 3D printers are suitable for parts with complex shapes. In terms of precision, high-precision machine tools are still slightly better. Besides, current 3D printers are all so small. Many of your parts are huge, and 3D printers can't handle them."

“That’s alright. First of all, our machine tools aren’t very precise to begin with; secondly, the fact that 3D printers are small now doesn’t mean that they will be small in the future. If we can make small ones, we can make large ones.” Ma Shan said happily, “The principle is the same, it’s just a little more difficult, but man can conquer nature.”

Liu Hua smiled and said, "That makes sense, but the technology for metal 3D printers is not yet up to par. Don't daydream. We still have many problems to solve."

"For example?"

Liu Hua curled his lip: "It's used to melt those metal powders, which requires laser technology. We're still working on overcoming the difficulties." "Hey, what are we talking about? Our laser technology is world-class. We can use it to strangle the Americans." Ma Shan said proudly: "Leave the matter to me. I'll apply to the higher-ups and request the top laser experts from our military research institute to help you."

Ma Shan was a soldier, brave and decisive, with first-rate actions; he submitted the report that very day.

Of course, there are considerations at the top. It's impossible to approve something immediately just because of a report. After consulting with experts in detail, it was confirmed that this thing is indeed beneficial to our military development.

After speaking with Liu Hua to understand their current research progress, and through comprehensive analysis and evaluation, four laser experts took on the task of developing the laser nozzle.

This laser expert is truly a laser expert, and he's one of the top experts in the country in this field. In less than two months, he came up with a concrete design plan. This efficiency left the two physics professors from Tsinghua University feeling far behind.

This autumn, the cold wind was particularly bleak, and everyone felt that a major change was taking place in the world. But when winter truly arrived, everyone knew where this change came from.

Our northern neighbor, the Russian bear, is an enormous behemoth with the world's most powerful army and the most powerful nuclear arsenal.

Such a powerful entity, whose every move could shake the world, ultimately collapsed with a bang, leaving one with a sense of melancholy.

The Americans felt that they were about to kill the Russian bear, so they were smug and proud, and began to swagger around the world.

Previously, many people in China were afraid of everything, thinking that the powerful United States was invincible. As a result, the trend of worshipping foreign things and fawning over foreigners became more and more rampant.

Foreign Minister Wang said it so well: Let him be strong, the breeze still caresses the hills; let him hate, the bright moon still shines over the great river.

The Great Leader once said that imperialism is a paper tiger.

Some worrying signs have also emerged at Tsinghua University. Some people have started to promote the idea that the United States is superior, trying to sway some wavering students towards the American perspective.

"We really need to clean up the academic atmosphere." Liu Hua said bluntly to the dean, "This is a university in our country, and it is meant to cultivate talents for our country. If this continues, who are we cultivating for the future? I'm afraid all the talents will end up benefiting our competitors."

"Professor Liu, don't exaggerate."

Liu Hua waved his hand: "Is this alarmist? Look at the concepts some teachers convey to their students: we're here to change the world."

The dean frowned: "There's nothing wrong with what he said. They are students of Tsinghua University, the pride of heaven, and naturally they should shoulder the great responsibility of changing the world."

"The person who conveyed this concept has ulterior motives in his words," Liu Hua said with dissatisfaction. "He told the students that we are here to change the world, thus blurring the concept of the nation. As long as we can change the world, we don't care which country it is. Science has no borders, but scientists have a homeland. He is unwilling to build his own country, yet he wants to change the world. It's utterly ridiculous."

The dean leaned back in his chair, carefully considering Liu Hua's words. The more he pondered them, the more interesting they seemed, and gradually, he began to agree with Liu Hua's ideas.
