Siheyuan: Grassroots Counterattack

There was no way. Li Tianyi's guess was too important and the director also needed to report to his superiors, so the topic was not continued.

Afterwards, the director asked Li Tianyi about his future plans, and Li Tianyi reported to the director about the current research projects of everyone in the compound.

When the director heard that the engine could be upgraded, he became obviously more interested. At present, Sijiu City has arranged for the arsenal to produce such engines. The previous pursuit and blockade can be said to have given Sijiu City a satisfactory answer.

If the engine can be further upgraded, does it mean that our country's fighter jets have the potential to surpass those of Country M?

The two talked a lot about this, and Li Tianyi also asked about the amount of materials he applied for, and why there was still no news after several months.

But the director had no idea about this. After listening to Li Tianyi's narration, he made a phone call on the spot and told Li Tianyi with a gloomy face that because the Ministry of Foreign Affairs had been busy with the campaign in the past few months, no one was there to help Li Tianyi buy the materials.

Afterwards, the director asked Li Tianyi to rest assured that he would help him keep an eye on the matter. Li Tianyi was unable to say anything and could only thank the director for his help.

Finally, the director asked Li Tianyi to stay in Sijiu City for two days. He would report Li Tianyi's situation to his superiors first, and might look for Li Tianyi again later.

After finishing the conversation, Li Tianyi took Xiao Zhou and the others back home. Before going home, Li Tianyi sent a telegram to Xiao Xue to report that he was safe.

Due to the confidentiality of the project, Li Tianyi had cut off all contact with the outside world, so there has been no news about Li Tianyi for more than two months.

During the two days at home, Li Tianyu also learned about the current situation of the steel mill through his father and others. Currently, under the management of Li Huaide, the steel mill is relatively stable. Of course, there have been many house searches and criticisms.

On the other side of the Siheyuan, Yan Bugui was sent to sweep the streets, and the family's only source of income was the few dollars he earned from sweeping the streets. Fortunately, Yan Bugui had saved some money from his translation work in the past few years, so the family did not starve.

On the Li family's side, there were also people who were jealous of the Li family and wanted to take the opportunity to put a blame on the Li family and bring them down, but they were stopped by Li Huaide.

After a few incidents like this, the others realized that the Li family could not be touched, so they gave up the idea.

Li Tianyi wanted his parents to go to the Northeast with him, where their safety could at least be guaranteed in the military region. However, Li's parents disagreed. One reason was that his younger sister was not married yet, and they were worried about her staying alone in the old city.

Another reason was that Li Tianhu's wife was pregnant. When Li's mother learned the news, she went to see her and said that she could come to take care of the pregnant woman.

But he doesn't want it. His wife said that her mother would come and live with them and also look after the children.

Li's mother didn't say anything when she saw this. Since the other party couldn't use them, why would they rush forward?

Two days later, the Military Commission contacted Li Tianyi again and told him that the materials he needed had been purchased and would be delivered to him within 10 days at the latest.

Li Tianyi was very happy. The director asked about the purpose of this material. Li Tianyi casually told him about his own experiment on invisible coating.

The director was shocked. He didn't expect that Li Tianyi had already started doing this kind of experiment before the enemy plane was shot down. The director said that his superiors would fully support Li Tianyi's work.

After that, Li Tianyi could contact him directly, and he would communicate with his superiors without having to convey the message through other people.

It was also because the superior leaders saw the problem this time that they made this decision.

Since graduation, Li Tianyi has made many important contributions to the country, especially this time, he had just arrived at the military region and solved a problem that others had no idea about for two months, which made Sijiucheng see his value even more.

Afterwards, the director specifically told Li Tianyi that their compound had been completely renamed the Second Institute, and said that if Li Tianyi wanted to return to the old city, the institute could be moved here as well.

Li Tianyi expressed his gratitude, but he still didn't want to come back. He had seen the chaos in Sijiu City in the past two days, and he was afraid that he would fall into this quagmire and be unable to get out if he came back.

The director did not force it. He also knew Li Tianyi's concerns, so he just mentioned it casually.

After saying goodbye to his family, Li Tianyi boarded a train to the northeast. After several days of journey, they finally arrived in H City safely.

After leaving the train station, Li Tianyi and the other two took a car back to the military region and briefly reported the situation to Commander Sun. Although their research institute is now in the Northeast Military Region, it is not under the jurisdiction of the Northeast Military Region. They are directly under the jurisdiction of Sijiu City.

Therefore, Li Tianyi reported to Commander Sun only out of respect for Commander Sun. After all, their safety still depended on him.

After returning home, Li Tianyi kissed his wife and son for two days before going to work.

After instructing the two group members on their issues, Li Tianyi began to arrange for people to move the materials he had prepared previously to his own research room.

Of course, another happy thing is that their research institute has been listed, which makes the members of the two groups very happy. Li Tianyi discussed it with Deputy Director Zhou, and then notified the canteen to prepare something delicious at noon to celebrate.

In the following days, everyone in the institute was more motivated, but Li Tianyi did not go anywhere. He stayed in the institute's office and began to study the enemy aircraft drawings he had drawn before.

There were three copies of that notice in total, one was archived by the state, one was distributed to other experts, and Li Tianyi kept the remaining copy himself.

He did not intend to study the existing instruments here, but wanted to use these instruments to study more advanced technologies.

He has a reserve of knowledge about fighter jets in his mind, and by looking at these drawings, he can better understand and absorb the knowledge in his mind, and more sparks will collide.

The core parts of a fighter jet include the engine, flight control system, weapon system, avionics system, and a stealth coating.

Now that the engine is under study, the remaining parts are worth studying.

Sure enough, the time given by the superior this time was accurate. On the 10th day, a car came from the research institute, accompanied by people from the military region, and they delivered the materials together.

Li Tianyi thanked these people, and after they left, he immediately arranged for someone to send the materials to the laboratory.

From this day on, Li Tianyi began to immerse himself in his work again. This time, the experiments he needed to do were more complicated. Although he had roughly mixed the materials, he needed to find the right ratio of materials.

He needs to mix the dozens of materials one by one and find a more suitable formula.
