Start with a blacksmith shop

"Okay, let's leave it at that. The company is still expanding.

You need money everywhere, but this money is already pretty good! "

Liu Xiaodong and Liu Xiaodong then agreed to the dividend plan, and together they made a plan for the company's development next year.

After talking about work matters, all that was left was to eat and drink. One of the two lambs was eaten by them.

After eating and drinking, they went back to their respective homes. Li Zhenhua and Li Yun returned to the hotel.

"Let me go home with you this year to celebrate the New Year!" The two of them were sitting on the sofa. A TV series was playing on the TV, but neither of them was paying attention to the TV.

Hearing Li Yun ask this, he fell into silence and waited for a while before answering her question.

"I won't go to Haicheng this year. I'll just stay at the blacksmith shop. By then, the people building houses behind will have left, and there will be no noise at home, so I will go back to live directly.

Also, in Haicheng last year, some customs were not followed, but that is not the case this year. The family still has to make offerings, and on the second day of the second grade, I have to visit the graves of my grandfather and parents. There are so many things! "

After Li Zhenhua finished speaking, Li Yun did not force him to go to Haicheng. She also had her own thoughts in her heart.

As the new year approaches, things in the company become even busier, but none of this has much to do with him.

It has no impact on him and he still maintains his previous pace of life!

On the 26th of the Lunar New Year, Li Yun went home, and after he left, he moved back to the blacksmith shop.

When he was alone at home, he felt more free. As the Chinese New Year approached, he no longer planned to go to the company.

This time was just right for him to get into the virtual laboratory and conduct his own research.

In the laboratory, existing chips are optimized with the help of an analytical eye using a precision of fifty nanometers.

In his hands, the photolithography knife also played a great role, but as he drew more and more chip circuit diagrams,

He gradually developed a sense of disgust towards this repetitive work, but when he focused again on the photolithography knife in his hand,

He was immediately stunned, as if he had entered a misunderstanding. Why did he have to carve it with his hands?

What is the difference between humans and animals? People can use tools, but animals can't.

Why doesn't he upgrade the lithography machine from a precision of 1 micron to 0.05 micron?

A feeling that I was very stupid and wasted a lot of time came to my mind. Then he started studying photolithography machines.

I erased everything in front of me in the laboratory, and then re-embodied the purchased micron-level photolithography machine.

Looking at the original lithography machine re-appeared in front of me, I felt like a lot of time was wasted.

Instead of taking the shortcut, I chose the most difficult path.

And as he gained a deeper understanding of lithography machines and chip manufacturing, he gradually felt his ignorance.

There is a truth, the more knowledge you have, the more ignorant you will feel, because when you don’t understand, you will feel that something is easy to do.

But as my knowledge gradually increased, I also understood how difficult it was to do what I had to do.

Suddenly he felt that he was really lucky to have been able to make the chip before. This was only possible in the virtual laboratory.

If this were to happen in reality, let alone rubbing out a chip with his hands, just a clean room would be enough to stump him.

It was after having these ideas that he gradually lost confidence in the idea of ​​rubbing chips against his opponents.

If the chip is to be rubbed out in reality, it will be a huge project. The first thing to do is to build a clean room that reaches Level 1.

There is still a lot to do in reality, but with their current size, they simply don’t have that much money to build these things.

Since then, he has completely abandoned the idea of ​​rubbing chips by hand, because it is simply impossible to achieve in the current reality.

It seems that everything I did in the virtual laboratory was in vain.

But this also made him realize what the chip industry was. From what he learned, Kyushu still had a long way to go.

Lying on the bed, he opened his eyes again and looked at the dark room. He sighed, turned over and fell asleep.

But Li Yun faced pressure from her parents after returning to Haicheng, thinking that she came back alone and did not bring Li Zhenhua back.

Ding Yan once thought that the two of them had broken up, but after subsequent cross-examination, she also found out the reason.

Although the two of them are not married yet, in Ding Yan's eyes, their relationship can be said to be a certainty.

After understanding the reason, he let Li Yun go.

During the Spring Festival, people also have free time. A large number of people are watching TV dramas and using TikTok at home.

It was at this time that the video of the Antarctic team, which could be described as a movie plot, became popular.

The reason why it became popular is also very simple. This time it became popular because it started from the external network.

A scientific expedition team from the Antarctic team of the Mold Country encountered the same situation as the Kyushu Antarctic team when they went out for a scientific research mission.

They also faced broken ice, but their snowmobiles didn't play much of a role.

There were six snowmobiles in total, but only two came out in the end.

The remaining four vehicles and the four people on board were all buried in the Antarctic facing the broken ice.

After the only two people left ran back to the scientific research station, they reported the incident.

The videos used as evidence were also submitted to it, and one of the staff members also posted these videos online.

An exchange student from China in Kyushu, after seeing the video, immediately thought of the video he had seen on Kuaishou before.

The two videos showed the same situation but different results, which was a bit difficult for the young man to accept at the time.

Then the two videos were edited together and posted on KuaiDou International. Then the video became popular and was moved back to Kyushu from KuaiDou International.

The snowmobiles that led the Kyushu Antarctic scientific expedition team members to escape death became the focus of people's attention.

But even if people searched all over, they still couldn't find the brand of this motorcycle.

Amid people's curiosity, a large number of people suddenly flooded into the official website of the Antarctic Station, almost all of whom came to inquire about motorcycles.

But it’s the Spring Festival now, it’s already holiday, and no one on the website has answered this question.

At this point, this matter has been shelved.

Li Zhenhua spent this New Year very traditionally, and the customs during the New Year remained the same as when his grandfather was still alive.

After the New Year, work resumed on the seventh day of the lunar month, and Li Yun also came back on the eighth day of the lunar month.

The days that followed returned to the usual calm. The house behind the blacksmith shop was almost completed, and everything on the exterior had been installed. All that was left was decoration.

The newly established factory area is still under construction, and it is estimated that it will take three or four months to be fully put into use.

After Li Zhenhua put down his obsession with rubbing chips by hand, he devoted all his energy to the manufacturing of aircraft mechanical parts.

As for the flight control, avionics and other things of model aircraft, now we can only purchase ready-made chips on the market for research and development.

As time passed, he finally got all the materials needed for the model aircraft, and then started manufacturing the model aircraft engine.

Among these materials, the most difficult ones are those used in the core combustion chamber. After a series of overcoming difficulties, these materials were finally produced.

The single crystal nickel-rhenium iron alloy in front of him took a lot of effort to produce.

And for this alloy, he also specially created a controllable magnetic field to arrange the single crystals of this alloy.

The manufacturing of the engine completely replicated the process in the laboratory, and the experience accumulated in the virtual laboratory finally came in handy at this time.

The first thing to manufacture is the engine combustion chamber casing. The diameter of the engine is reduced to 29 centimeters. His machining center is fully capable of manufacturing this casing the size of it.

He put a forty centimeter-long square single crystal nickel-rhenium iron alloy into the machining center. This piece of metal was the new high-temperature alloy smelted previously.

The light curtain in front of him showed that the internal stress of the piece of metal had almost been released.

The little internal stress that was left allowed him to take a rubber mallet and knock it out with the help of his analytical eye.

After placing the metal in place, as he pressed the start button, the cutter head of the machining center rotated at high speed, and the milling cutter cut bits of debris on the metal.

As the cutter head rotates, debris falls off the originally square metal block, and its shape also changes with the cutting.

Slowly, as more and more chips were chipped away from the metal, the metal no longer regained its original shape.

After a day of manufacturing, the upper part of the metal block has been shaped into a round shape with holes by the machining center.

In two and a half days, he took out a complete combustion chamber casing from the machining center.

And he also stayed here in the machining center for two and a half days, watching the operation of the machine.

Take the processed casing out and put it aside for later use, and then start to make the impeller, wheel disc and other parts in the combustion chamber.

The processing of the wheel disc is relatively simple, but the processing of the impeller blade is a bit difficult.

Because the machining center he is using now cannot meet the accuracy requirements at all, this also forces him to use the machining center to make a preliminary rough blank.

After that, he took out the rough blank, fixed it on a vise, and rubbed it by hand with a file.

One blade after another was rubbed out in his hands, and the twisted blades were also installed on the impeller plate.

When it was installed on the wheel plate, I started to notice the dynamic balance problem of the impeller.

His eyes and hands are not perfect either, and dynamic balance can only be considered a minor problem.

The turbojet engine was also taking shape bit by bit as he was being manufactured.

Time slipped away quietly while he was building the engine. After more than a month of building the engine, he finally rubbed it out with his hands.

At this moment, in the center of the workshop, he was standing next to an iron shelf, and on the shelf was the already manufactured turbojet engine.
