1959: Carrying the achievement system, she rolled

As soon as Du Yimeng came back, she saw Yu Lang, wearing an apron, busy in the kitchen.

"You're back, wash your hands and get ready to eat!" Yu Lang said, and then took out the food that was warm in the pot.

"I think it's a pity to leave you at home and do these trivial things every day." Du Yimeng said while washing his hands.

This is true. It is a bit of a waste for such a capable person to spend all day around the stove.

"What's a pity? I think this is great. It's nice to be able to cook for you every day and wait for you to come home for dinner." Yu Lang said with a smile.

He put the dish in his hand on the table, walked to Du Yimeng and hugged her gently.

All his brothers envied him. The person he protected was his own wife. How lucky he was.

"Did you eat candy today? Why are you so sweet?" Du Yimeng felt warm in her heart and hugged him tightly. The water droplets on her hands just happened to rub against his back.

"There are sweeter ones. Do you want to try them?" Yu Lang said in a tempting voice.

She used to dislike him for not being able to speak, so he worked hard to improve himself and strive to become the most perfect husband in her mind.

Du Yimeng: She felt he was driving, and she had evidence.

"Stop it. I have to go back to work overtime after dinner." Du Yimeng was unsociable and wanted to push the person away.

A kiss fell on the corner of her mouth before he let her go. This was what he was talking about. What was she thinking about?

"I also have something to do later. I'll pick you up from get off work when I'm done." Yu Lang said.

He had been gone for twenty days and had a backlog of work that needed to be dealt with. He had originally felt a little uneasy about leaving her alone at home.

Now that she works overtime, he can focus on his work.

"Okay, I might be very busy for the next while, you..." Du Yimeng felt a little guilty when she said this.

They only had one day of leisure on the second day after their wedding. It seemed that they didn't have any wedding leave or honeymoon or anything.

Apart from the fact that there were multiple people sleeping in her bed every day, she felt like she was in a fake marriage.

"It's okay, your work is more important!" Yu Lang picked up a piece of bacon with chopsticks and put it in her bowl, saying with a smile.

The night before he left, his father specifically told him not to cling to her and not to disturb her work.

He felt that the roles of the two people had completely reversed, whether it was his father, or him and her.

"When I have time in the future, I will definitely make it up to you." When she is not busy in the future, she will definitely take a long vacation to make up for the honeymoon period.

But she didn't know that only when the national defense and military industry system was fully developed could she be less busy.

"Okay, I'll listen to you." But Yu Lang understood it to mean something else. His deep eyes flashed and the smile on his face deepened.

Du Yimeng paused holding the chopsticks. She always felt something was strange, as if they had swapped roles.

She became the domineering president, and he was the little wife who stayed at home waiting for the domineering president to come home.

She quickly put all this mess out of her mind and took a bite of the food, which made her miss the dishes cooked by Qian Donghua.

She is worthy of being a kitchen worker. Even if she is not a chef, her cooking skills are very good. No wonder Wan Ping wants to lose weight after eating the dishes cooked by Qian Donghua.

From despising Wan Ping at the beginning to understanding him now.

"The bacon you fried today is so delicious!" Du Yimeng's words were full of praise. Apart from being a little salty, it was quite delicious.

Ever since she praised Wan Ping heavily over the phone that day, she seemed to have turned on some kind of switch.

She had praised Yu Lang before, but not to such an extreme degree.

"Then eat more!" Yu Lang picked up another piece of bacon with his chopsticks and put it in Du Yimeng's bowl. However, he was reluctant to eat it himself because there was not much bacon.

He didn't think much of it because he hadn't tasted it himself and he only used a tiny bit of salt when cooking.

But he forgot that bacon is salty and needs to be scrubbed before eating...

This cannot be blamed on him. It can only be said that he always eats ready-made bacon and has never made it himself.

Du Yimeng: ...

She was very curious about how those scumbags managed to be scumbags without getting shot?

……

Du Yimeng returned to the laboratory and compared the two drawings.

The reason why the Type 51 has a longer range than the Type 56 is that the former uses a multi-nozzle turbine rocket engine.

It can increase the initial speed of the rocket when it is launched, thereby achieving a longer effective range.

The Type 56 is similar to a traditional bazooka, but is closer to a recoilless rifle.

To put it simply, its firing method is somewhat similar to that of mortars and launchers.

Her eyes fell on the super-caliber rocket-propelled grenade. She felt that the reason why the Type 56 was equipped to the troops was that it had its own advantages, such as this.

Then her gaze shifted to the Type 51's rocket engine, and her eyes lit up.

Is it possible to install a rocket engine on the Type 56?

Certainly not a multi-nozzle turbo rocket engine, which is outdated and cannot achieve the effective range she wants.

And since she could think of this, the weapons research department must have thought about this problem as well.

This means that the Type 51 engine cannot be used on the Type 56, so this can be ruled out.

The mechanical engine, which she was best at, was also not suitable because it was too large, so it was directly ruled out.

She believed that if she could solve the problem of small size and maximize power, she could develop the best-performing rocket launcher.

She directly put the two drawings into the drawer, and then put them back into the space.

Even in a research institute, locked drawers aren't always safe. If the two blueprints are lost, they'll definitely be punished, so it's best to be cautious.

Then she turned and went straight to the library.

"Teacher, what type of engine is small in size and can produce the greatest power energy?" Du Yimeng came to the library, sat down next to Qin Chulong, and asked.

For every student, of course they should ask the teacher if they have any questions.

"Fuel engine, but..." Qin Chulong answered subconsciously, then he turned his head and looked at Du Yimeng with sharp eyes.

He was pretty sure she had an idea, otherwise she wouldn't have asked this question.

"Teacher, but what?" Du Yimeng asked.

"However, it requires special fuel, otherwise it will need to be continuously supplied with fuel to make it work. There is no way to do this, so we can only increase the space for storing fuel. In this way, its advantage of being small will be lost." Qin Chulong explained.

"Continuously supplying fuel is definitely not an option, but we can make an internal combustion engine?" Wan Ping came to them at some point and immediately suggested.

Their major is mechanics, and engines are Du Yimeng's specialty, so there is no problem at all.

Three months is still plenty of time...
