Several heads of the military's General Armament Department and the General Logistics Department held a joint meeting and consulted for a long time, and finally decided to maintain the status quo and send many plainclothes to the campuses of Yenching University and Shuimu University. Secretly protect Liu Shiqing. This decision was made after consulting Liu Shiqing's opinion.

Liu Shiqing knows very well that under the current conditions. There is no such thing as a safe place, even in a barracks. I don't dare to say that it is absolutely safe, and all kinds of accidents can happen at any time. Only wait for the ultra-high-precision CNC machine to be manufactured. He was able to make some equipment, and then some of the most high-tech personal protective equipment.

Of course, it is not enough to have ultra-high-precision CNC machine tools, and it also needs the support of many industries. Liu Shiqing made a phone call to Ding Chongxiang and asked him to take the opportunity to acquire an electronic device factory with a good domestic reputation and specializing in the production of resistors, capacitors, and circuit boards, and to acquire or control a steel plant. Ding Chongxiang didn't know what Liu Shiqing wanted to do, but he still followed Liu Shiqing's request and asked the investment department to find a suitable acquisition target across the country.

Duan Liyi and Chen Junjie were rescued by the hospital and quickly woke up, and after careful examination, the hospital confirmed that the two of them had no other internal and external injuries except for a slight concussion. The hospital asked two people to be hospitalized for observation for a week. In addition to prescribing the right medicine, closely observe them to see if there are any sequelae left.

Liu Shiqing and Guo Qianrong went to the hospital to visit the two of them, sitting at the head of Chen Junjie's bed, Liu Shiqing said with a smile: "Junwei, you always brag to me, saying how elite you are, ten or eight men can't get close, on the battlefield, invincible and unstoppable." But if you look at it, you were hospitalized last summer, and now you're here again, and I doubt how much braggart you have in that statement. ”

": Uncle Bu, I'm also a sick person. Can't you be more compassionate? Chen Junwei pursed his lips and his eyes fell on Guo Qianrong's body, "You let the little aunt comment, as the old saying goes." No matter how good the kung fu is, I am afraid of kitchen knives, and this elite is also afraid of bombs, Major Duan and I are only a mile away from the center of the explosion, and the two of us can be safe and sound. ”

"Seeing that you talk so slippery, I know you're okay. Take good care of your illness, there is one less person chirping around me in the past two days, and I am really a little unaccustomed. That's 50,000 dollars. Buy some nutritious supplements, replenish your brain, and don't look back. The head was concussed and turned into a pig brain. It's troublesome. Liu Shiqing laughed as he spoke.

"Only 50,000? Uncle Junior, you're too stingy. Saying this, Chen Junwei's action of grabbing the check was quite fast, "If I do this twice, I will be able to save my wife's book." ”

Liu Shiqing shook his head, "You're just going to be like that?" Do I need to exchange my life for saving my wife? When you get married in the future, I will cover the expenses of your daughter-in-law, and keep it so that the master and the senior brother are satisfied, and it will also make your kid so happy that he can't keep his mouth shut. ”

After visiting Chen Junyi, Liu Shiqing went to visit Duan Liyi again, Liu Shiqing also took a check of 50,000 yuan to Duan Liyi, but was rejected by Duan Liyi, she is different from Chen Junyi, Chen Jun's sister is thick-skinned, and her grandfather is Liu Shiqing's master, and she never treats herself as an outsider, but she can't. Her relationship with Liu Shiqing is not good enough to be that kind of Cheng dù.

Besides, she is still an active soldier, and she was ordered to come over to protect Liu Shiqing, so how can she ask for money.

Duan Liyi refused, and Liu Shiqing couldn't force the money to her, so she had to ask Yang Nuoting to buy more nutritional products and send them over to express her heart.

Back in the expert building, Tao Haotian and Song Yihan talked to Liu Shiqing very seriously and formally. The central idea is only one: "Let Liu Shiqing wear two more body armors for his own safety." If you can, try to bring a bulletproof helmet.

Liu Shiqing couldn't cry or laugh, "I said two." One body armor is enough, but if I wear two, I will be dirty and swollen like a big fat man, and it is not convenient to move at all, if I bring a bulletproof helmet, I guess others will really think that I am on the battlefield in Iraq or Afghanistan. This is China. It's our own territory. ”

Tao hated Tianyan and said, "Mr. Liu." I know it may be a bit reluctant to do this, but as you can see, we originally thought that the campus of Yenching University was the safest place, but someone touched it and harmed Professor Fei's father and daughter. If the target of them is you, we will not receive any information in advance. I don't dare to guarantee 100% that I will be able to protect your personal safety. If you wear two more pieces of body armor, you can prevent some unexpected situations more. ”

Liu Shiqing muttered, "Okay, since you think that I can reduce some accidents by wearing body armor, then I'll design and manufacture a few body armor by myself." ”

Tao Haotian and Song Yihan were both stunned, "Mr. Liu, are you kidding." Inferiority clothing is not something that anyone can make, if you are simply worried about a lot of clothes with a lot of pockets, and stuff steel sheets into it, forget it, ordinary steel sheets will not work at all, you need to use special steel, or professional ceramic sheets. ”

Song Yihan also said: "Mr. Liu, body armor needs to meet three functions, first, anti-pistol and rifle bullets; secondly, to prevent shrapnel from grenades, mines, and artillery shells; Third, to prevent non-penetrating injuries, that is, bullets hitting the body. Although it did not penetrate the body, its powerful impact force caused huge damage inside the human body. If you want to meet these three needs at the same time, it is not a simple matter, the era of sewing a piece of clothing casually and stuffing steel sheets into it has long passed, and manufacturing body armor requires very professional knowledge.

"How do you know if you don't try? Anyway, recently, I've been reading books all the time, and my head is a little confused. It's time to have some fun and whet yourself. Liu Shiqing said half-truthfully, "I guard the two colleges and universities of Yenching University and Shuimu University, and I don't believe that with the current conditions, I can't make better body armor." ”

Tao Hatian and Song Yihan looked at each other, not knowing how to dissuade Liu Shiqing. The two had no choice but to turn their attention to Guo Qianrong for help, hoping that the latter could help them persuade Liu Shiqing. Material. Guo Qianrong's gaze at them for help was basically oblivious. There are many people who trust Liu Shiqing unconditionally in this world, and there are many people who believe that Liu Shiqing can create miracles again and again, but choose one of these people who trusts Liu Shiqing the most. Probably none other than Guo Qianrong.

Guo Qianrong and Liu Shiqing have been classmates for two years. witnessed a little change in Liu Shiqing, and saw Liu Shiqing go from ordinary to today. In addition, she also walked out of Liu Shiqing, the only one who knows that the strengthening drink is the product of dilution of the strengthening agent mixed with water, since her boyfriend can create so many miracles, why can't she create a second one?

"Shiqing. I believe that you will be able to design and manufacture world-class body armor Guo Qianrong's tone is indifferent, but the power contained in it can be felt by everyone present.

Liu Shiqing smiled faintly, "I definitely can't complete this task alone, I don't know if my Ms. Guo Qianrong, the director of the Direnshi yàn room, can do me a small favor?" ”

Guo Qianrong couldn't help but be happy in her heart, no matter what scientific research projects Liu Shiqing had done before, she had never let her participate in them, and today she asked her to accompany him to make zuò body armor, which undoubtedly consolidated the relationship between the two people, the relationship between honor and sharing, life and death. Guo Qianrong did not hesitate at all, and nodded, "It is an honor for a little woman to serve the chairman." ”

Song Yihan and Tao Hatian have a headache, I don't know which one Liu Shiqing and Guo Qianrong are singing, is Liu Shiqing really capable of making body armor?

Liu Shiqing pondered for a moment, then turned his head and said to Song Yihan and Tao Hatian: "I need the help of the military to help me get the spider sister silk."

Tao Haotian nodded, "I'll help you inquire right away and see if you can get spider girl silk there." ”

About half an hour later, Tao Haotian and Song Yihan had a result, "Mr. Liu, things are a little troublesome. ”

"What's going on? What's the trouble? Could it be that spider silk is a strategic material and cannot be allocated to me? Liu Shiqing asked.

Tao Hattian shook his head, "Spider girls are ferocious by nature, and they are carnivorous animals, as long as the breeding density is slightly larger, they will devour each other. Therefore, it is very difficult to breed artificially, so before the production of natural spider silk is considerable, people's research on spider silk mainly stays in the stage of artificial imitation, and the spider silk protein is synthesized artificially by means of genetic engineering. ”

The physical and chemical properties of spider silk are compared to silk. It has very obvious advantages, in terms of mechanical strength, spider silk fiber is close to the highest strength of carbon fiber and high-strength synthetic fiber, Zhika, and other strengths, but its toughness is significantly better than the above fibers. According to scientists studying the experiments. A bundle of rope made of spider silk is stronger than stainless steel bars of the same thickness. It is able to withstand 5 times more weight than steel bars without breaking.

At present, the most advanced manufacturing technology of artificial sister silk is still in the United States. The National Army Biochemical Command Center in Massachusetts, USA and Nexhire Biotechnology Company in Quebec, Canada, took out the spider gene from the spider and implanted it into the goat's body, so that the goat milk has spider silk protein, and then used a special silk-like procedure to spin the spider silk protein in the goat milk into * artificial gene spider silk, which is also known as biosteel (day. ）。 The artificial genetic spider silk produced in this way is 4 to 5 times stronger than steel, and has a silk-like softness and luster, which can be used to make high-grade body armor. Biosteel has a wide range of uses, and can also be used to make protective shields for combat aircraft, tanks, radars, satellites and other equipment. (To be continued)
