In the next few days, Xiao Jingwen was looking for high-strength materials, he consulted several of the largest domestic ceramic and glass manufacturers, asked them for the data of the strongest materials, and found that they were not enough bulletproof standards, if they were rashly used, they would be smashed into pieces by bullets and pierced into the human body, which would cause greater damage.

As for the high-strength fiber fabric, it can barely find one among the firefighting materials, but the performance is much worse than Kevlar, but it is better than nothing.

Xiao Jingwen told Jiang Nan about the situation, Jiang Nan thought about it for a long time, and suddenly thought that some arsenals would have this kind of high-strength material, the arsenal made weapons, and the materials would not be bad.

But they couldn't get into the arsenal, and no one could take anything out.

Jiang Nan really had no choice, so he went to find Gu Xiancheng.

"You said you want to make body armor?" Gu Xiancheng was surprised.

"Yes, Zhengang is about to go on a mission, I heard that this mission is very dangerous, I am worried about ......" Jiang Nan said: "If there is body armor, the danger will be greatly reduced, and if it can be made, it will have a great effect on our army and police force." ”

Gu Xiancheng nodded, having said that, can this kind of thing be made by a private enterprise?

"Dad, I know it's not easy, I just want to make one first, I need your help." Jiang Nan said.

Listening to Jiang Nan's words, Gu Xiancheng frowned, but agreed to give it a try, anyway, the daughter-in-law is thinking about her son.

"Dad, you don't need materials first, you ask them for the data of the strongest materials first, let's see, if it doesn't work, then don't use it." Jiang Nan said.

Gu Xiancheng began to call, after all, he was the commander of the military region, and the leader of the arsenal still gave face, and it was not confidential just to ask for material strength data, so he quickly gave the data.

Jiang Nan reported these data to Xiao Jingwen, but he said that it was still not enough.

"Not enough?" Jiang Nan was surprised, if the materials in the arsenal were not good, then what could be better than this?

"Unless ......" Gu Xiancheng paused, seeming to hesitate a little.

"Unless what?" Jiang Nan was in a hurry, and it would be too late if there was no more.

"Unless it's aerospace or submarine materials." Gu Xiancheng said.

yes, why didn't I think of that? Jiang Nan's eyes lit up, there was no higher strength material than these.

But isn't it a bit overkill for these materials to be used in body armor?

"That'...... Are these materials hard to come by? Jiang Nan asked worriedly, even if Gu Xiancheng is the commander of the military region, he can't speak in these two areas, right?

"I want to figure it out!" Gu Xiancheng said.

"Actually, you don't need much material, at most half a square is enough, it's really not okay to have such a piece......" Jiang Nan gestured at the heart, mainly to protect the heart, even if other places are shot, there is still hope of rescue.

Gu Xiancheng nodded, "I'll try!" ”

After a day, Gu Xiancheng didn't know what method to use, and finally brought a few palm-sized materials, which looked like they should be leftovers, but even if it was this material, Jiang Nan knew that it was Gu Xiancheng who spent a lot of favors to get it.

She immediately took the materials to Xiao Jingwen, and Xiao Jingwen was very surprised when she got the materials, "This is aviation materials, right?" ”

Jiang Nan nodded.

"It's still my sister who has a way." Xiao Jingwen was very excited, it was the first time he came into contact with this material, and he flicked it with his hand, "It's really hard enough, it seems that it takes a diamond gold hacksaw to see it." Jiang Nan, don't worry, I will not waste it, and I will help you make it immediately. ”

"Be quick, Zhengang will leave the day after tomorrow." Jiang Nan advised.

"Okay, I'm going to do it even if I don't sleep." Xiao Jingwen nodded.

It wasn't until the morning of the last day, when Yang Zhengang was about to set off, that Jiang Nan received a bulletproof vest.

"It's finally done, but unfortunately I don't have time to experiment, and I can't guarantee the results." Xiao Jingwen handed the bulletproof vest to Jiang Nan, "The strength of our outer layer of fiber material is still not enough, I added a layer of strength metal steel fiber, which should still play a certain role, and the middle layer is aviation material, which mainly depends on it." ”

"Thank you, third brother!" Jiang Nan was very excited to take the bulletproof vest, and with this, there was no need to worry so much.

Jiang Nan asked Xiao Jingheng to drive him to the military region, but Xiao Jingwen hadn't slept for a few days and didn't dare to let him drive anymore.

Jiang Nan thought about going to get a driver's license instead, so that he could cover up the fact that he could drive, Xiao Jingheng knew that he could drive, but if he drove to the military region and was seen by Yang Zhengang, it would be difficult to explain.

When they arrived at the military region, Yang Zhengang and the others were already preparing and were about to set off.

I was surprised to see Jiang Nan coming, "Why are you here?" ”

"I'll send you something!" Jiang Nan said.

"Let's go to the office, then!" Yang Zhengang nodded.

There was no one in the office, and Shen Xiang was also busy outside.

Jiang Nan went to take off Yang Zhengang's coat when he entered the office, and he was stunned, "Daughter-in-law, what are you doing?" ”

Do you want to come back again before leaving? He wanted to, but he didn't have enough time.

When Jiang Nan saw him, he knew that he had misunderstood, and gave him a blank look.

"What do you think? I'm just going to add a dress for you. Jiang Nan said.

"No, I'm thick enough." Yang Zhengang said.

Jiang Nan ignored him and took out a bulletproof vest from his backpack, the vest was a bit heavy, maybe two or three kilograms, this is still using aviation materials, otherwise it would be heavier.

Without saying a word, let Yang Zhengang stretch out his hand and put the bulletproof vest on him.

"What kind of clothes are so heavy?" Yang Zhengang clearly felt the difference.

"It's body armor." Jiang Nan said, "This was made by our brothers and sisters for a week, by the way, and Dad's credit." ”

"Body armor?" Yang Zhengang was surprised, he had heard of it, but the troops did not have it at all, and they were not in a position to wear body armor now.

"Actually, it's very rough, and I can't guarantee the effect, but it's better than nothing." Jiang Nan put on the bulletproof vest for Yang Zhengang and put on his coat, "Remember, you have to wear it every day, and you must never take it off unless you take a shower!" ”

"Daughter-in-law, you are so nice!" Yang Zhengang lowered his head and grabbed Jiang Nan's lips and kissed it, I don't know how long it will be before I kiss my daughter-in-law, I am really reluctant.

Just when he couldn't suppress the fire, Yang Zhengang braked in time and hugged Jiang Nan tightly into his arms, "Daughter-in-law, wait for me to come back!" ”

Jiang Nan's eyes were a little wet, "Give me a good return, don't get hurt!" ”

"Yes, Chief!" Yang Zhengang suddenly made a military salute to Jiang Nan.

Jiang Nan's eyes were red, he smiled with tears, stood on tiptoe and pecked Yang Zhengang's lips, pushing him, "Let's go!" ”

Yang Zhengang glanced at her deeply, didn't say anything more and turned to leave, he was afraid that he would be reluctant to leave if he didn't leave.

Jiang Nan opened the door and watched the whole team leave, leave the military region, and get into Xiao Jingheng's car to go back to school.

Xiao Jingheng looked at her sideways, there were still tears in the corners of her eyes, and she was silent for a while and said, "Don't worry, my brother-in-law will definitely be fine." ”

Jiang Nan raised his head to look at him and raised a smile, "Well, it will definitely be fine!" "I want to talk about "Rebirth of the Eighty Prosperous Wedding Pets" with more like-minded people, and pay attention to "excellent reading literature" on WeChat, talk about life, and find confidants~
