The door of the courtyard house has been welded dead

Institute laboratory.

The people surrounding Ran Qilin and helping him changed again, and they became several college students wearing military uniforms and white coats.

Some of the first batch of college students who were led earlier are already able to carry out independent experiments and conduct introductory material research under the guidance of Professor Ran.

In more professional terms, this is called designating a topic and conducting collaborative research.

Li Feng's arrival caused several college students to immediately stop their work and salute Secretary Li, who was also wearing a military uniform.

After the guidance of retired soldiers from the institute, at least it looks like that.

"Secretary Li~!"

"Director Li~!"

"You all go out for a moment, I want to talk to Professor Ran about something~!"

Li Feng waved his hand and looked at Director Ran, who was still observing something in front of the microscope. Compared with his previous sloppy image, he was much cleaner now. He wondered if it was the result of his daughter's supervision.

Director Ran was the same, wearing a white coat like a hospital doctor, but unlike these students, he was not wearing anything underneath, but the green military uniform that had already been issued~!

Secretary Li hooked a stool with his foot, but did not interrupt his research process. He put his arms on the table and waited quietly.

It was not until Ran Qilin's eyes were probably sore that he looked up from the microscope and noticed Li Feng's arrival.

Looking at Li Feng in military uniform, who looked a little different from Secretary Li in the past, Ran Qilin raised his eyebrows but did not say anything to him.

"Why don't you wear the clothes you were given?"

Pinching the corner of his collar and looking at the shirt underneath Ran Qilin's white coat, Li Feng asked.

"I think no matter what I wear, it won't have any effect on the test results~!"

Ran Qilin didn't say that he didn't want to wear it, didn't want to wear it, or that it was uncomfortable to wear. Instead, he used another way to tactfully reject Li Feng's question.

"Yes, you can do research in a suit, but this suit is for those who defend their country. I still hope that one day you will be willing to wear our clothes and take this honor as your own~!"

Li Feng clasped his hands together and curled his lips. If arrogance had levels, then Ran Qilin in front of him was the most arrogant person he had ever seen.

"Why can't clothes just be clothes? They are just a tool to keep body temperature~!"

"I think you must have a problem, that's why you choose to come here, just like me, I won't go to your office~!"

Ran Qilin spread his hands, not intending to dwell on the clothes any further, and asked directly about the purpose of Li Feng's visit. As for when he would wear the clothes that were distributed to him.

That's his freedom, since he's wearing a white coat anyway.

"Okay, if we don't consider the cost, we can use titanium to make the back plate of the bulletproof insert. I want to ask if it is technically feasible?"

"Regardless of the cost, it is technically feasible, but it requires the addition of some aluminum to effectively increase strength and toughness. Of course, based on the current industrial base here, it will probably be ten times more expensive~!"

When discussing technology, Ran Qilin was not as resistant as before, and gave appropriate suggestions according to Li Feng's requirements.

"However, the processing technology will be very difficult and the man-hours may be very long. You have to know that this is just a research institute. It is very different from alloy steel~!"

Shrugging his shoulders, Li Feng said that cost was not a consideration, so Ran Qilin also did not consider the cost. However, he still had to say the ugly truth in advance: it was impossible to rely solely on the research institute for mass production.

"I will let the workshop make it specially. One is the feasibility of the formula, and the other is its weight. How much lighter can it be than the current alloy steel? Will the strength be reduced?" Li Feng has no theoretical knowledge in this area. However, there are professionals here, so he doesn't need to worry about these. After all, it is used by the big guys, so no matter how expensive it is, he has to buy it.

What was promised to Xu Zhongyi was the standard for defending against pistol bullets. This is called a negotiation skill. Asking for a sky-high price and getting a low price. Once the research is finally done and it is higher than the expected standard, everyone will be happy.

But if the standard he agreed to is high, but the score he submitted is not high enough, he will have to face accountability from Boss Xu.

Although they are fighting on two fronts, Party A’s background is so deep that Li Feng doesn’t even know which people will be deployed.

"For the same volume and area, titanium-aluminum alloy is about 40% lighter than steel alloy. As for strength, it depends on the processing technology, which may be around 1.5 to 2 times~!"

There was no need to do any calculations on manuscript paper. All the experimental parameters were already in Ran Qilin's mind, and he could answer them at any time.

As for why Li Feng came up with this alloy back panel and where it would be used after it was developed, he didn't want to interfere at all.

"Try to produce a few pieces first. I'll take a look at the situation. If you need materials and equipment, you can contact Li Xuewen. He will coordinate the work~!"

After understanding the situation more or less and getting the expected answer, Li Feng still had to go to the ceramic workshop.

After the weight of the back panel is reduced, what remains is the ceramic panel, which is customized in thickness and is definitely different from the standard military version.

The total weight is 6.8 kilograms. If the bulletproof ceramic can be reduced by 40% further, the total weight can be controlled to around 4 kilograms.

Of course, Xu Zhongyi did not give a clear indicator, limiting the weight to a few kilograms.

Li Feng didn't know whether four pounds was too heavy for him. If the ceramic plate could have a replacement material like the back plate, Li Feng wouldn't have such a headache.

Liu Haizhong didn’t know how much of a headache Secretary Li was having.

But today, Old Liu was unusually majestic. He began to imitate Li Feng and carried a briefcase in his hand when he went out.

A meeting was held in the factory staff quarters to discuss which people would be brought to the Red Star Community by him and would be officially in charge of a small business under his leadership.

That’s right, they are all a group of middle-aged people, about the same age as Lao Liu. The young people like to hang out in groups of three or five on the streets and don’t have much interest in managing the community.

"Lao Zhang, can I rest assured that I will continue to leave this sewerage project to you?"

Old Liu, wearing glasses, sat in the center of the table, holding a pen in his hand and taking notes in an open notebook. He looked quite capable.

"Director Liu, don't worry. If I can't do it, my third child knows someone in the Construction Bureau, and he knows someone who can guarantee that it will be smooth. If there is any problem, come to me. However, as for the septic tank...!"

The old man whose name was called blushed. He didn't expect that he would have a day to work in the community after he had some free time. He had originally planned to find something to do, but he didn't expect to become a regular soldier.

Compared with the septic tanks in the factory housing estates, the Hongxing Community is different. Once it becomes large in size, it is full of oil and water.

"The factory is the factory, and the outside is the outside. I will apply for funds from the street as everyone's salary. We just got there, so we can't mess around with these things~!"

Old Liu is still sober about this. After all, the scale is different. There are only a few buildings in the factory housing estate, and the septic tank is only enough for one village. It is even more impossible for him to own all the people living in the Red Star Community.

"Over at the garbage station, Lao Mei and Lao Zhang, the factory family quarters sewers are newly built, so there won't be a big problem in the back, but there are more than 3,000 households and tens of thousands of people in the back, which is different from the buildings in our factory family quarters. The number of households that need to be transported is different~!"

Let’s put interests aside for now. After all, you get a day’s work and a day’s salary. You can make plans after you become familiar with the specific operations of the community. At present, you just need to decide on the personnel who will maintain the operation of the community.

Things were arranged, and he led people there, so he felt confident. (End of this chapter)
