Siheyuan Back to the 1950s

At this time, there were drawings placed on the workbench. Chen Wanchun picked up the drawing of the suspension system and felt more and more uncomfortable the more he looked at it.

When Zheng Wenhua saw his master's expression, he knew that something must have gone wrong again.

"Master, the ball head and bushing have just been strengthened, why are you still sighing?"

Hearing his apprentice's words, Chen Wanchun shook his head and explained: "It's not the ball head or bushing that's the problem, it's the spring. The spring stiffness is not enough and is far from meeting the standard."

After hearing this, Zheng Wenhua also knew the consequences of not being tough enough.

But he had no choice. They were mechanical researchers and could not develop special steels.

Just then, Sun Zhengguo walked in from outside. Seeing him coming, Zheng Wenhua thought of someone.

"Master, why don't we let the director think of a solution? Doesn't he know Wang Lefeng from the Iron and Steel Research Institute? Would that crazy Wang not help him?"

"You mean Wang Lefeng? He is good, but...? Oh! It's useless, useless, don't ask why."

Chen Wanchun directly denied his apprentice's idea. Couldn't he have thought of this?

No, the main reason was that he couldn't find Wang Lefeng, because just half a year ago, this person mysteriously "disappeared" and he didn't know where to find him.

At the same time, based on his experience, Wang Lefeng was most likely transferred to a secret scientific research unit, so he didn't let his apprentice ask.

"What are you discussing?"

Seeing Sun Zhengguo coming, Chen Wanchun had no choice but to tell the truth.

"Director, the new car's spring stiffness is not enough, what should we do now?"

"Oh! Lao Chen, can you tell me specifically how much pressure the current springs can withstand?"

"Okay, director."

Chen Wanchun already knew all these data by heart, so he didn't even need to look at the information and just blurted them out.

"After testing, each wheel now bears about 400 kilograms of pressure in static conditions, and even less than 800 kilograms in dynamic conditions."

Hearing this data, Sun Zhengguo couldn't help but frown.

It's OK in static state, barely passable, but in dynamic state? It's not good enough.

According to this data, once a car is on the road, with a few more people on it and the road conditions are worse, it will probably be broken.

After pondering for a moment, Sun Zhengguo still couldn't solve the problem, but he had already thought of someone who could provide the solution.

"Okay, Lao Chen, let me solve this problem. If you have any other questions, you can raise them all at once."

"Other problems are not serious and can basically be overcome."

After hearing what Chen Wanchun said, Sun Zhengguo was still a little worried, and the two of them discussed these issues again.

It was not until half an hour later that Sun Zhengguo left the small workshop, then went to the laboratory, and then to the branch factory...

After he walked around and found no problems, he returned to the office and made a phone call.

At noon, not long after lunch, a military jeep arrived at the institute on time.

Needless to say, the person who came was Staff Officer Lu. Chen Zhonghua was already used to seeing this and hurried to call for help.

"Zhonghua, it's still the same old rule. If you have an emergency, call that number."

"Okay, director."

After giving the instructions, Sun Zhengguo picked up his briefcase, went downstairs, got in the car, and drove all the way to the Military Research Institute.

The journey was uneventful.

Half an hour later, the car arrived at the destination. Staff Officer Lu went back to report, while Sun Zhengguo went directly to the laboratory.

Over the past year or so, he has come and gone as he pleases, and has become extremely familiar with the place.

When Engineer Wan saw Sun Zhengguo coming, he quickly ran over to say hello.

"Director Sun, you are here again."

Sun Zhengguo smiled and nodded, "Wan Gong, you're welcome. By the way, where is my teacher?"

"He's testing new materials in the lab! I'll go call him."

Engineer Wan works in a hurry. After saying that, he ran to the next room.

Looking at his agile movements, which didn't look like the movements of an old man, Sun Zhengguo couldn't help but shake his head and smile bitterly.

Through the contacts over the past year or so, Sun Zhengguo has more or less gotten to know these experts and has long admired them.

Some of them have been doing this boring work in hiding for more than ten years.

Even their family members don’t know whether they are dead or alive.

Sun Zhengguo thought he couldn't have such a fearless spirit of dedication.

Really!

Maybe he can do it in a year or two, but he really can't do it in ten or twenty years.

While Sun Zhengguo was still daydreaming, Professor Wu walked out of the room.

"Jungguk, didn't you just come here a few days ago? Why are you here again?"

"Teacher, I have no choice. The development of the car has reached the last minute and it is stuck with materials, so I have to come here."

After hearing what his apprentice said, Professor Wu nodded, understanding that he came to find Wang Lefeng.

"Then let's go! Engineer Wang has just finished developing the materials for us and is doing experiments with me in the lab!"

Sun Zhengguo nodded and followed the teacher inside.

Who knew that as soon as the two of them entered the room, a burst of crazy shouting came from inside.

"It's done, Professor Wu. The new high-temperature resistant material has passed the test perfectly..."

Immediately afterwards, Sun Zhengguo saw a famous scene.

I saw Wang Lefeng with a messy hair jumping up and down, performing an inexplicable dance.

"Oh! He really lives up to the name of Crazy Wang." Sun Zhengguo sighed lightly.

"Cough, cough, cough!"

Professor Wu coughed and reminded, "Um...um, Mr. Wang, Zhengguo is looking for you."

Hearing the voice, Wang Lefeng turned his head with a look of surprise.

"Hey! That's not right! Professor Wu, how did you come in from outside?"

However, when Wang Lefeng saw Sun Zhengguo, his expression instantly changed to surprise.

“Jungguk, when did you get here?”

“Hahaha!” Sun Zhengguo laughed and said, “Old Wang, I just got here too. I hope I didn’t affect you.”

"No, no, I should thank you! If you hadn't reminded me last time, the new high-temperature resistant material wouldn't have been completed so quickly."

As he spoke, Wang Lefeng took out the test data sheet and handed it to Professor Wu.

Professor Wu took the data sheet, skipped the first part and looked at the final result. Then, a look of surprise appeared on his face.

"Not bad, not bad. It can actually withstand temperatures over 2000 degrees. It's a big improvement over the original setting. Great! I really have to thank you, Engineer Wang."

When Wang Lefeng saw Professor Wu was happy, he also felt happy.

He has never had any pursuits in his life and only likes dealing with steel. Now that he can be recognized, he feels extremely satisfied.

After reading the data sheet, Professor Wu prepared to go to Director Ma to report, so he instructed his apprentice.

"Zhengguo, I'm going to Director Ma's place. Don't you have something to do with Engineer Wang? It's a good opportunity for you two to talk."

Having said that, Professor Wu left the room. Only after he left did Wang Lefeng react.

"Jungguk, why didn't you tell me earlier that you had something to talk to me about?"

"Hey! Isn't this just in time? I also have some materials here and I need your help."

"No problem. In this life, as long as you, Sun Zhengguo, come to me, I will never say no."

Wang Lefeng agreed without even thinking about it, and his words revealed his gratitude to Sun Zhengguo.
