Seeing that the kids all had problems, Du Yi didn't rest anymore.

Get to work right away.

She stood by the blackboard and answered the questions one by one.

Then explain the other knowledge points again in a coherent manner.

The Death Force had been listening to "new knowledge" for the entire morning, and every brain cell was now hungry.

I wish Du Yi would keep talking without stopping.

This knowledge cannot be found in books at all, it is simply the most useful knowledge.

After seven days of study, they will definitely be able to design new weapons on their own.

After just half a day of study, they have endless ideas in their minds.

Du Yi looked down at the cubs who were like crying baby birds waiting to be fed.

I smiled slyly in my heart.

After three days, I'll make you want to vomit just by hearing my voice.

Ha ha……

For the rest of the afternoon, Du Yi gave lectures without stopping.

It didn't end until we missed dinner time at eight o'clock.

"Okay, I've given you all the theoretical knowledge on the thirteen types of firearms. The test will be in two hours."

"Preview of tomorrow's class, the first half of the development of thirteen types of guns, good luck!"

Du Yi threw the chalk into the box, clapped his hands, and said with a relaxed look on his face.

One sentence brought everyone back to their senses from the ocean of knowledge.

Xu Yang jumped up and said, "Ah, the quiz is only two hours away. This day has passed so quickly!"

Cui Ze quickly turned to the first page of his notes and looked at it.

He didn't forget to say, "Number One, give me a steamed bun."

Liu Hua smacked his lips and said, "The team leader is testing what I said today, right?"

The air suddenly became quiet.

Twenty-three heads looked at Du Yi who was walking out.

Du Yi did not even turn his head and jokingly asked: "Guess?"

The twenty-three people's faces turned black: "..."

Can the team leader be a human being?

Five minutes later.

Du Yi appeared in the new dormitory.

After being promoted to regimental commander, the army allocated her a two-bedroom suite.

He didn't have time to collect it when he was on a mission before, but Xiao Shian has prepared it today. He also moved some of his daily necessities from home.

From now on, when the two of them are in the army and don't go home, they will live in this suite.

Zheng Kai lives on the left side of the house, and Du Haojun lives on the right side.

They are all acquaintances.

"Captain Du is back, come and try the dumplings I made."

Zheng Kai happened to be taking a day off today and was helping Xiao Shian move house. He then went back to his dorm and made some dumplings.

"Thank you."

Du Yi washed his hands, sat down, and looked up to thank him.

Xiao Shian filled a bowl of dumplings and placed it in front of Du Yi, with a faint smile on his face: "This is what he should do. The five people eliminated from the Death God Special Operations Team are now the technical instructors of our regiment."

Zheng Kai chuckled and thought this production chain was very good.

Du Yi trains the Death God Special Operations Team, and the eliminated personnel will go to their regiment to train other soldiers. In time, the Leng Feng Assault Regiment will become stronger and stronger.

Du Yi raised his eyelids and glanced at Zheng Kai.

It’s fine if my own men’s group comes to take advantage.

She said, "We are currently conducting a closed-door training session on light weapons. When it's over, I'll give you some notebooks."

"Okay, okay."

Zheng Kai's eyes sparkled.

"Captain Du, the sniper rifle you designed has an accurate range of 2,200 meters, which directly breaks the world record. This is amazing. Vice Dean Zhong plans to take the sniper rifle to the competition, and he will definitely win first place."

"Contest?!"

Du Yi frowned and slowly put down his chopsticks.

"The old man didn't tell me about this."

"I gave him the blueprints to make weapons specifically for the Death God Squad. If I take them out to compete, won't everyone in the world know my trump card?"

She looked at Xiao Shian with a serious expression: "An, I will go to give the Death God Team a quiz later, you contact the old man and tell him the situation."

It was the first time that Zheng Kai saw Du Yi look so serious.

He immediately put down his chopsticks and said, "But, that gun has been seen by many people, and the test results are probably already spread."

Du Yi didn't care after hearing that.

"It's okay. There are still a few issues with the sniper rifle that need to be adjusted. I set the precision sniping range of this gun to three thousand."

“Three thousand!!!”

Zheng Kai's voice suddenly rose and he almost broke.

The range of the most advanced sniper rifle in the world is only 1,500 meters.

Xiao Shian also looked at Du Yi with surprise.

Du nodded, tapped the table and said, "After you finish eating, go back to your dormitory and don't disturb our short time together."

Zheng Kai: “…”

He was the one who made the dumplings.

Xiao Shian quickly put away his surprise and couldn't help laughing out loud.

Seeing that Xiao Shian was indeed busy, Zheng Kai quickly finished his dumplings and went to the motor camp to drive.

"Captain, I'll go drive first."

After Zheng Kai left, Xiao Shian started talking about personal matters: "Do you need other materials for making bulletproof vests? I'll go apply for them."

Du Yi fed the man a dumpling: "No need, there is everything in the space."

"I can find you a replacement."

Xiao Shian also picked up a dumpling for Du Yi.

He knew that there were many materials and weapons in the space, but those things were becoming less and less as they were used, and sooner or later they would run out.

Du Yi still shook his head: "Bulletproof vests are for saving lives. I want to use the best materials. But I will be leaving for a mission at the beach soon. Can you help me get some steel so I can make steel needles?"

"good."

After dinner, Xiao Shian went to the Military Research Institute without delay.

Du Yize entered the space's arsenal, decomposed the KS-1A micro-materials, peeled these materials into single layers, and then weaved the rebound material into them through a special weaving technique to make a three plus two sandwich material. Only at this step was the bulletproof material made, and then it was sewn according to the style.

What she has to do today is to decompose the KS-1A micro-material.

After an hour and a half of work, the alarm rang.

Du Yi took off his gloves and work clothes, left the space, locked the door and went to the regiment headquarters.

It is almost lights-out time. Outside the officers' dormitory building, the corridors of other buildings are filled with soldiers in shorts, holding basins and fighting in groups.

Du took a glance.

It seems that the training during the day was too easy and they still have energy to play around.

No wonder China can’t even make it into the top ten in every international special forces competition.

When I have time, I will write a training plan for the commander and discipline these soldiers.

As I walked and thought, I soon arrived at the regiment headquarters.

As soon as Du opened the door, he saw twenty-three people, all facing the wall and muttering to themselves.

The entire hall of the regiment headquarters was filled with the buzzing sound of people reciting lessons.

"Let's get started!"

Du clapped his hands.

It's nine fifty-nine.

Twenty-three people turned around quickly, and some of them even dropped their notes on the ground nervously.

Du Yi stood up and casually pointed at Cui Ze, the unlucky guy.

Cui Ze's face turned pale and he walked to the front with his buttocks tucked under him.

In a voice that was almost tearful, he shouted, "Captain!"

Everyone else held their breath and turned to look over.

It's scary to be eliminated on the spot.

This is really a test of their psychological quality.

The team leader only said that the assessment time was fixed, but did not say anything about the number of assessment questions or rules.

Du Yi didn't give Cui Ze time to buffer, and immediately asked expressionlessly: "If an M1 sniper rifle wants to increase its accurate firing rate to 2,000, what adjustments need to be made?"

Cui Ze's eyes lit up. He knew the answer to this question.

Others also started thinking quickly about how they would answer if this question was asked to them.

"No thinking allowed, answer immediately."

While Cui Ze was laughing, Du Yi yelled sternly.

Cui Ze shuddered and blurted out: "Lengthen the barrel by 30mm, install a fixed tripod, and change the buttstock to a mid-bend style..."
