1959: Carrying the achievement system, she rolled

"The weight of the engine cannot be controlled to the lightest, and the cost will be very high. You mentioned before that widening the track will reduce the ground pressure. Have you taken this into consideration?" Qin Chulong asked.

According to her, a compressor, a combustion chamber, and a turbine are needed. For a system to function, auxiliary systems are also needed.

Not only that, high temperature and high pressure mean that high-temperature resistant materials are needed, and the cost may be surprisingly high.

"Well, if you want the engine to start quickly and respond quickly, this is the only way." Du Yimeng said that if you want to develop more advanced tanks, you can't consider the cost issue.

Considering what Director Wei said, what else does she have to worry about?

As for why she insisted on the tank starting quickly, don't underestimate this point. It's like two people competing. Whoever is faster can take the lead and gain the advantage of time, place and people.

Before you draw your sword, my sword is already on your neck. That’s the concept.

"I need to think about this first." Qin Chulong did not agree immediately, nor did he raise any objections.

Although it is just theory now, he can estimate the data first. If the conclusion is feasible, then he can conduct research in this direction.

There's no other way, it's because of financial constraints. These people don't do research by simply thinking of something, but first make estimates, draw conclusions, and then proceed with actual operations.

"It's getting late, you should go back and rest early!" Qin Chulong said to Du Yimeng after he came to his senses. As a workaholic, he remembered that this student should not be too tired now.

"Teacher, you should go back and rest early. Some work doesn't need to be rushed." Du Yimeng saw Qin Chulong's tired face and began to persuade him. If he continued to work at such a high efficiency, his body would definitely not be able to bear it.

"Yes! Teacher, you should go back and rest early. I feel that you have more white hair on your head recently." Wan Ping also advised. He felt that the teacher had aged a lot recently.

"Student Du, do I have more white hair?" Qin Chulong ignored Wan Ping and turned to ask Du Yimeng.

"No, it's the refraction of light that makes Comrade Wan have this illusion." Du Yimeng explained quickly, and then she glared at Wan Ping secretly. Does he have to tell the truth?

Can't you just keep it in mind?

She understood Qin Chulong's mentality very well. The older he got, the less he liked people mentioning words like white hair or old age.

To put it simply, people are old but refuse to admit it, and sometimes white lies are necessary.

"Yeah!" Qin Chulong nodded in satisfaction. This student was indeed considerate. Even if it was like trying to cover up his mistake, he felt relieved to hear it.

When he first started his relationship with Wen Yan, he paid great attention to his image and would dye his hair from time to time.

He thought that standing next to Wen Yan would make him look less old. Now that he has a wife and children, and is too busy with work, he has no time to care about his image.

Wan Ping on the side was also helpless. The teacher always told them that they should never lie at any time.

But now that he has told the truth, why does the teacher like to hear lies again?

"I'll go back and rest first. Wan Ping, please pack up these materials." Qin Chulong gave instructions and left the laboratory without looking back.

He only has some clues now, but it is still a long way from starting work. It would be a waste of time for him to stay here, so he might as well rest early.

The main reason is that he is too tired recently. After he has a good rest, he will continue working tomorrow with the best mental state!

"Comrade Du, how did you come up with what you just said?" Wan Ping asked impatiently as soon as Qin Chulong left.

They all have brains, so why can she think of these things?

"Of course I thought of it with my brain. Hurry up and pack up. I'm going back first." Du Yimeng said this and quickly left the laboratory. It would take a long time to explain it, so let's not talk about it!

It was really late, she had to go back and rest.

Wan Ping: ...

"Sister, Brother Wan is obviously very smart, why do we sometimes feel that he is very stupid?" As soon as Du Yimeng came out, Lao Wu couldn't help but ask, Brother Wan who is so smart is actually as stupid as him.

When he returned, he saw that his father had a lot more white hair, so he asked about it out of concern, but his father started chasing him with a stick again.

"What truth are you talking about!" Du Yimeng replied with a smile.

"You two siblings are plotting against me. Can you please keep your back on me?" Wan Ping, who was packing his things, heard the conversation between the siblings at the door and shouted outside.

He was praised for his intelligence and mocked for being stupid. He didn't know whether to laugh or be angry.

……

On the other side, Qin Chulong saw that the lights were still on before he entered the house. He subconsciously curled up the corners of his mouth and felt warm in his heart.

Among thousands of lights, there is one that is lit for him. It feels so good to have someone waiting for him and to be cared about!

Then he quickened his pace with a look of distress on his face. It was nothing for him as he was strong, but she was a double now and could not stay up late.

He warned her again and again, why didn't she listen?

Wen Yan was leaning against the head of the bed reading a book. Seeing that he came back so early today, she put down the book in surprise.

"Why aren't you sleeping yet? Didn't I tell you not to wait for me to come back?" Qin Chulong said with concern.

"It's still early and I can't sleep either." Wen Yan got out of bed quickly while speaking. Before she got married, she was always alone. She especially longed for the lights of thousands of homes, hoping that one of them would be lit for her.

She didn't know if he had the same idea as her, so after getting married she habitually wanted to keep a light on for him.

Seeing his distressed face, her smile became even brighter. He knew everything she did, but he was not good at expressing it.

At this moment, Qin Chulong also saw the little wood sleeping inside.

At this time, Xiao Mu was sleeping soundly, and a loving expression subconsciously appeared on his face.

He didn't know why, but whenever his son fell asleep, he felt that his son was perfect in every way, and that was when his fatherly love could overflow without restraint.

"Wash your hands first. Warm the food on the stove. After you finish eating, soak your feet in hot water so you can have a good sleep." Wen Yan poured some hot water into the basin and asked him to wash his hands.

"I'll do it myself, you go lie down on the bed." Qin Chulong stepped forward and took the thermos from her hand, and the latter smiled but did not refuse.

Wen Yan returned to the bed again and looked at Qin Chulong who was busy with work, her eyes full of smiles. So what if he didn't understand romance?

After getting married, it didn't stop him from loving his wife.

"Why did you come back so early today?" Wen Yan didn't ask until Qin Chulong finished his meal and started soaking his feet.
