Traveling through the sword to engage in military industry.

Semiconductors are too expensive. Ren Zhong's original buying model in the main world simply won't work when it comes to semiconductors.

The investment for a 6-inch wafer factory with an annual output of one million pieces would easily be 20 billion US dollars. This kind of wafer factory is already considered a low-level factory in the main world. If an 8-inch wafer factory is built instead, an 52-inch wafer factory with an annual output of 8 pieces would require an investment of up to 32 billion US dollars!

This is not a super money-eating beast that can be driven by ordinary capital.

As an ordinary billionaire in the main world, Ren Zhong's net worth is less than 8 billion, and he can't even afford to invest in a basic -inch wafer factory.

Of course, it's not that he absolutely cannot afford the investment. If he is willing to take out a loan, the local government will be happy to provide more than 80% of the loan support. The key is that Ren Zhong has no idea how to run the wafer factory business. If he makes such a huge investment, he will most likely end up hurting himself.

Ren Zhong can grit his teeth and invest 20 billion, but if it's more, there's no way. After all, the business he has now is not small. Although these factories are still profitable, it's hard to say whether they can survive on their own. Once there are fluctuations in the market, Ren Zhong will have to put in money.

The automobile industry in Black Africa seems to be on the right track and has gained a certain reputation in Black Africa. Whether it is civilian agricultural vehicles or pickup trucks, sales have formed stable channels in West Africa.

Being able to carry both passengers and cargo and being much cheaper than its competitors, Heifei's automobile factory is currently in good health, following the route of high volume. The Bobcat series of special vehicles have also opened up the market among local warlords and militias, but sometimes they receive minerals instead of US dollars, which makes it more or less inconvenient to convert them into income.

Fortunately, China has a strong ability to absorb raw materials. These ores received at a discount of more than 20% locally can be brought back to China by sea and earn a little more than the original transaction price.

Therefore, Heifei's automobile business is the strongest business under Ren Zhong. After sharing the profits with Heifei's Nigerian partners in a year, he can get about 2 million.

As for the battery business, the situation is not so optimistic.

It is very difficult to compete in the domestic market. Even though Ren Zhong keeps a separate account for R&D expenses, Jincheng's battery factory still has ups and downs in business, with profits and losses. The company is struggling on the brink of life and death. There is no way. A battery factory of this scale cannot be supported by Ren Zhong bringing some lithium batteries to the world of Liang Jian from time to time.

In the main world, Ren Zhong's battery factory has no technical advantages at all. On the contrary, apart from some innovations in assembly and safety, the battery cells are all purchased ready-made. It can be said that the core technology is not mastered at all. Such a factory does not squeeze labor costs and has little profit at all.

But Ren Zhong opened this factory in Jincheng. Regardless of whether he was willing to do so or not, the objective environment did not allow it!

Fortunately, the ups and downs over the years have basically been balanced out, and as a battery supplier for Heifei automobile factories, the company can still maintain a stable and profitable volume, so there is no risk of bankruptcy for the time being. As a result, Ren Zhong did not pay much attention to the company and let it develop freely.

As for the gaming peripheral factory, its current situation is neither good nor bad. It is slightly worse than the car factory, but much better than the battery factory. It makes a profit of several million a year. Following the development of games, it is constantly developing new peripherals. After Ren Zhong’s demand for weapon imitation research is no longer needed, they can make products closer to the market, and the results are actually better.

Anyway, now his three best friends have basically achieved financial freedom and are now starting to pursue their personal spiritual fulfillment.

They work diligently on the path they have chosen. Although they are small shareholders who receive dividends, they care more about the business than Ren Zhong, the major shareholder.

Under such circumstances, these industries with heavy responsibilities are of almost no help to semiconductors. Even as auxiliary support, they are of no use.

Ren Zhong returned to the main world, cleaned up his assets, and let out a long sigh.

It is impossible to operate a physical factory.

Given the current economic situation, even if he could still obtain valuables such as gold, jade, and antique paintings and calligraphy in the world of Bright Sword, the amount of cash he could convert into would be relatively limited.

Gold is fine, as it can be cashed in at any time in Hong Kong or overseas markets. Unfortunately, hard currency like gold is relatively scarce at any time, and it is difficult for Ren Zhong to get a large amount of gold from the world of Bright Sword. After all, it is not on a scale of tons, which is not of much significance to Ren Zhong. Thirty to fifty kilograms of gold and tens of millions of dollars in income are not of much help to Ren Zhong's career now.

Including jade and antique calligraphy and paintings, it would be considered good if we can steadily convert 10 billion yuan into profits every year on average.

Adding the accumulated investment income of more than 40 billion yuan in reserves, Ren Zhong's annual income is about billion or billion yuan.

But the expenses are also not small, including digging up information from the main world, hiring consultants, and maintaining a technical research team. For example, for material research, the research funding of Hu Rentao's team is at least tens of millions a year. Now that the scale is getting bigger and bigger, and the research topics are getting closer to the level of the main world, the expenses are even greater. Perhaps next year's budget will exceed 100 million.

Because they included the second-generation nickel-based high-temperature crystallization research in the plan, the reference object is the mature second-generation nickel-based single-crystal high-temperature alloy DD406 of Dongda University, which is required to have the advantages of high temperature strength, good comprehensive performance, stable organization and good casting process performance. This is prepared for the three-rotor engine jointly developed by Dongda University and John Bull.

与国外应用的第二代单晶高温合金PWA1484、ReneN5、CMSX-4相比，其拉伸性能、持久性能、蠕变性能、抗氧化性能及耐热腐蚀性能等均达到甚至部份超出其水平，且因其含Re量低而具有低成本的优势。适用制作具有复杂内腔的燃气涡轮在1100℃以下工作的涡轮工作叶片和1150℃以下工作的导向叶片等高温零件。在主世界，正是制造PW4000系列、FJ2000和RB211等发动机高温部件的不二材料。

The next generation WS-11 engine based on Spey also needs to use this high-temperature alloy. For Professor Hu Rentao's team, this project is their most challenging project to date.

Because all the detailed process flow and material formula are confidential, even if they have been researched in China, they will not be disclosed to them. All the process details have to be re-researched. For Hu Rentao, he does not understand the rationality of Ren Zhong's request, after all, the use of this thing is too narrow.

This type of high-temperature alloy is already produced in China and the market is almost monopolized. After Ren Zhong developed this product, there was almost no room for it in the domestic market. In the international market, this type of high-temperature alloy is also somewhat outdated. Now, mainstream aircraft engines in the world have basically begun to adopt third-generation or even fourth-generation high-temperature alloys, and there are not many aircraft engines that can match this type of high-temperature alloy.

Unless... Hu Rentao knew that in the big country in the north, there should be a lot of demand for this kind of high-temperature alloy, whether it is RD-33 or RD-93. Although they can produce some of it themselves, under the current circumstances, it is estimated that the production capacity is a bit limited. If there is a second-generation high-temperature alloy with low price and good quality, it will surely be very helpful to improve their production capacity.

Thinking about it this way, Professor Hu Rentao suddenly felt enlightened.

This Boss Ren is really wild, he can even do this kind of business now.

Compared with other materials, this material is indeed more profitable. The quantity is small and the unit price is high. One truck costs less than 20 million. After all, one ton is about , and a heavy truck of to tons is worth tens of millions. If this material is developed, although the market is small, it is still profitable.

However, Professor Hu Rentao never imagined that Ren Zhong's main sales location was not on the main world's Blue Star. It was really mind-boggling.

The closer the scientific and technological achievements of the main world are to modernization, the more difficult it is to obtain them, because behind every technology, systematic research and development must be carried out to overcome it.

For example, the production of a semiconductor wafer is an extremely complex process. After the wafer is completed, photolithography is a huge and complex system that turns the wafer into a chip. But do you think that's the end? No, the chip is still naked and cannot be used directly. It needs to be packaged and tested, which is another huge and complex system.

Some people say that chip manufacturing can be more complicated than nuclear bombs? In fact, it is true. The path taken by modern chips is much more complicated than nuclear bombs in almost every step in terms of the variables involved in the system, and it becomes more and more difficult as time goes by.

Nuclear bombs could be developed with the technological level of the 40s. So far, more than nine countries have directly claimed that they can manufacture and explode them. There are at least a dozen countries that are quietly researching and have the manufacturing capabilities. However, there is no country that can independently manufacture top-level EUV lithography machines. Even for the second-rate high-end DUV, no country can claim that it can produce it independently!

The country that came up with the EVU lithography machine is just an integrator, and it took the technology and components from the world's top countries to manufacture it!
Judging from the results, modern lithography machines are indeed the most technologically complex systems in the world, and perhaps it goes without saying that they are the second most complex systems in the world. Because before this, aircraft engines were known as the pearl of industry, but compared with high-end lithography machines, there are many more countries that can win this industrial pearl than lithography machines. At least in reality, the five permanent members of the UN are all capable of independently producing aircraft engines.

Even with spaceships and space stations, there are now several different factions that can do the job independently.

This system is so complicated that even a billionaire like Ren Zhong cannot dive into it and complete it from beginning to end.

After returning to the main world, Ren Zhong sorted out the situation and concluded that for semiconductors, the focus was to continuously collect and organize system information of this system through technical consultants, from collecting manuals of ancient I-LINE lithography machines to production process descriptions to principle structures. Ren Zhong took the perspective of creating academic works and the name of writing practical teaching materials for the training of semiconductor industry talents.

According to this idea, the I-line lithography machines that appeared in the main world between 2000 and 2010 can provide more research objects to choose from. You can even buy some old second-hand i-line lithography machines to create a chip manufacturing laboratory model to build a complete chip factory.

School of Electronics, Jincheng University of Science and Technology.

Dean Liu Xueren and a group of people were waiting at the entrance of the college, awaiting Ren Zhong's visit with some anticipation.

"Dean Liu, could he be a liar? How come such a good thing suddenly happened to us?" Professor Chen Shude, who was in charge of the development of semiconductor physics, asked suspiciously.

"Professor Chen, it seems that you have been scammed too many times. People no longer have the basic sense of trust in each other." Professor Sun Shanhe, who is in charge of microelectronics, joked, "Whether it is a scam or not, we old guys will only waste half a day at most. It's not a big deal."

Liu Xueren looked at them twice without saying anything. If he was not 70% sure about this matter, why would he go to such great lengths to call all the technical leaders of these colleges together to welcome him?

Because in the previous contact, the billionaire named Ren Zhong had clearly expressed the idea of ​​building a laboratory together with the School of Electronics. Professor Liu Xueren had a brief understanding of Ren Zhong in advance and found out that he was a true billionaire in Jincheng. Although no one could clearly explain how Ren Zhong became rich, it was possible to find out from the Internet that several companies with annual output values ​​of over 100 million yuan were closely related to Ren Zhong.

Especially there is a very profitable automobile company overseas.

In short, although this person is young, he is definitely not a liar.

What's more, the construction project is implemented in the School of Electronics, and no one is asked to pay for it, so Professor Liu Xueren does not have to worry about being cheated.

"Professor Chen, Professor Sun, and all my colleagues, I don't care what you think. We must maintain due respect for our guests during this reception. Mr. Ren Zhong is a genuine wealthy man. Although we don't know why he chose us, this may be a major opportunity for the infrastructure construction of our college. I believe you all know the importance of a sound infrastructure to our teaching and scientific research." Professor Liu Xueren glanced at his colleagues and said lightly.

Although no harsh words were said, everyone understood the implication.

These old professors are not out of touch with the world. Just as Professor Sun Shanhe said, everyone has come out and it only takes half a day. If it succeeds, it will be a pleasant surprise. If not, it will just be a waste of half a day for everyone.

"President Liu, I said too much. I promise to fully cooperate to complete this reception work." Professor Chen Shude, knowing that he had said something wrong, immediately expressed his opinion.

The others also nodded, indicating that they understood what the dean meant.

On the other hand, Ren Zhong came with a small entourage this time, driving his Maybach with a driver to the office building of the School of Electronics on time.

Ren Zhong was in the car, looking at the other party and seven or eight old professors with slightly bald heads waiting on the roadside, and he couldn't help feeling a little sorry.

He quickly opened the car door and walked quickly to Professor Liu Xueren and others.

"President Liu, I'm sorry. How dare I trouble you professors to wait for so long?" Liu Xueren was standing at the front. Although Ren Zhong had never seen him before, he recognized him from the picture introducing the professors of the college. He quickly stretched out his hand and shook hands with Liu Xueren tightly.

"Mr. Ren, you are too polite. You are a guest and it is our duty to greet you. Come, let me introduce you briefly. This is Professor Chen Shude, the leader of our college's semiconductor discipline, and this is Professor Sun Shanhe, the leader of our microelectronics discipline." After shaking hands, Professor Liu Xueren introduced his team to Ren Zhong with a smile on his face.

Ren Zhong shook hands and greeted these old professors one by one, and the guests and hosts returned to the VIP meeting room upstairs chatting and laughing.

Since it was known in advance that Ren Zhong would come alone, the conference room was not arranged into two columns for host and guest, but was arranged in a circle, and Professor Liu Xueren and Ren Zhong sat next to each other.
