1959: Carrying the achievement system, she rolled

"I think the shape of the cartridge case should be designed to be cylindrical and conical, so as to reduce wind resistance and increase the speed of armor-piercing bullets." Wan Ping said as he looked at the simple drawing drawn by Du Yimeng.

"Your idea is very good." Du Yimeng nodded and said. The system rewarded her with a drawing. The cartridge case on it was saddle-shaped, which was completely different from the round and conical cartridge case proposed by Wan Ping, both in shape and structure.

Although the two types of sabots have the common feature of reducing wind resistance, the former focuses on flight stability and improving hit rate, while the latter focuses more on armor-piercing ability.

The former has a more complex design, while the latter is traditional.

"Why don't you object this time?" Wan Ping asked Du Yimeng with a puzzled look on his face. Sometimes he felt particularly helpless.

Because he didn't understand what she knew, but she could explain what he knew very clearly.

There is no way for him to survive, which makes him crazy!

To be honest, he has been trying very hard. When he washed his hair this morning, he lost several hairs, and he was very worried about it!

Du Yimeng: She wanted to object, but she didn't have the chance to speak, and she was afraid of undermining his self-confidence.

She was very worried that he would become depressed because of the constant pressure on him. She was particularly afraid of losing this good helper because she would be the one who suffered in the end.

In fact, she didn't want to always raise objections, but she felt that what she proposed was more feasible.

"I think we should improve the cartridge case. While ensuring its penetration capability, we should also enhance its accuracy." Du Yimeng considered her words before speaking. Her words made Wan Ping fall into deep thought.

Wan Ping: He also thought of this problem, but he didn’t know how to improve it!

Unlike Du Yimeng, who can change things as soon as he says so, what if he tells him to change things?

What can he use to change it?

Are you willing to risk your life to change it?

A feeling of frustration arose spontaneously, and then he immediately stood up. The reason for this must be that he didn't work hard enough.

huh huh...

He dared to swear on his own character that he really worked hard!

"It's time for dinner. You can discuss it slowly after dinner." Qin Chulong left this sentence, picked up the lunch box and turned to leave.

At the rate their discussion is going, it will take at least two hours to finish, so let's eat first!

Anyway, the two of them don't need him now...

Du Yimeng and Wan Ping's eyes all fell on Qin Chulong's back.

In the past, when eating, Qin Chulong always stayed until the last one, forcing the two of them to eat half-warm food with him.

In fact, the time wasted is the same whether it is morning or evening. It is of course best to eat hot food.

It’s not a big deal in the summer, but it’s really comfortable to be able to eat hot meals in the winter.

No matter how young they are, they don't want to put themselves in such a difficult position.

But now Qin Chulong has changed. He is actually more active in eating.

After the two looked at each other, they saw the raging fire of gossip in each other's eyes.

Du Yimeng quickly looked away and lowered his eyes to hide the gossip in his eyes.

As someone who respects teachers, how could she possibly think of reading gossip about her teacher!

"Before, when we were discussing problems, the teacher rarely gave us advice. I thought it was because the teacher didn't know much about tungsten alloy armor-piercing bullets. Now it seems that there are other reasons as well." Wan Ping began to analyze the situation one by one.

The more he analyzed, the brighter his eyes became. At this moment, he seemed to have returned to his student days, just like the brilliant academic master he once was.

"I think your analysis of the situation is very thorough!" Du Yimeng silently gave Wan Ping a thumbs up, worthy of being a little gossip expert.

Wan Ping raised his head proudly at first, but the next second, his eyes began to dim, and his head slowly drooped.

In the past, among the three teachers and students, only Du Yimeng had a fiancé, but at least there was a single teacher to accompany him.

Now the teacher has a partner, but he is still single.

We agreed to be single together, why did you leave him behind halfway?

He is so sad...

When will his spring come?

If it was a long wait, just for that moment, he hoped to remove the long wait in the middle, because he only liked the result.

Du Yimeng saw him like this and sighed silently in his heart. He could survive the misfortunes sent by Heaven, but he could not survive the misfortunes brought upon himself. Who could he blame for this?

She and Wan Ping studied the same major, and after entering graduate school, they had the same teacher and learned the same thing.

It can be said that in this world, the two people who have the most common language are them.

But if Wan Ping still discussed work matters with her after get off work, she really couldn't help but give him a stick.

If you put yourself in her shoes, she would feel the same way, let alone those female comrades who don’t understand their profession!

She can only blame herself. Every time she talks about their professions with other female comrades, she wants to ask, who can stand it?

"Eat..." Wan Ping quickly calmed down. It's just that he's single!

He is happy to be single and happy all the time...

"Actually, pursuing a lesbian is not about discussing academic issues with her. Instead, you have to speak to her heart, which means saying something pleasing." Du Yimeng said kindly.

"What do you mean?" Wan Ping, who had just picked up his lunch box and was about to leave, suddenly stopped and turned back to look at Du Yimeng with sharp eyes.

Why didn't he think of asking her for advice!

After all, she has a fiancé, and that alone makes her better than him.

As for the talk of being single, get lost...

"First of all, you have to learn to listen instead of talking. If others can't understand what you say, who would want to talk to you?" Du Yimeng said earnestly.

"Then what?" Wan Ping's eyes lit up.

"I'll go get the lunch box and talk while we walk." Du Yimeng had just finished speaking when Wan Ping disappeared the next second.

When he came back, he was holding the lunch box she had placed on the desk.

She raised her eyebrows in surprise, as if she had grasped his lifeline.

"And then?" Wan Ping asked again. In order to say goodbye to being single, he was willing to do anything, even doing the work of a younger brother.

Du Yimeng did not disappoint him. She then went on to explain to him how to pursue a lesbian.

Of course, she did not teach him the methods used in later generations to pursue girls. After all, in this era, subtlety was still important.

Even after a slight modification, in Wan Ping's eyes, she still became a love expert, and she actually saw admiration in Wan Ping's eyes.

During this time, they studied tungsten alloy armor-piercing bullets together. She knew more than him, and she had seen helplessness and depression in his eyes.

The only thing she didn't have was admiration, but I didn't expect that because of this reason, she actually saw it, which was very good.
