Siheyuan Back to the 1950s

Section Chief Lu trotted all the way to the technical department, found the drawings of the hot rolling mill, and then ran to Director Gao's office.

"Hey! Chief Lu, weren't you with Professor Wu and the others? Why are you here?"

Looking at the breathless Section Chief Lu, Director Gao asked in confusion.

"Director Gao... Director Gao, I want to... report a situation."

"Don't be anxious. Calm down first. What happened? It made you run like this."

"I'm fine, Director Gao, go check it out! Professor Wu and his team are preparing to fix the broken hot rolling mill!"

"What action?"

Director Gao still didn't understand what he meant and continued to ask.

But he seemed to think of something in an instant and stood up quickly.

"They don't want to repair that machine?"

Seeing Chief Lu nodded, Director Gao waved his hand.

"Come on, let's go take a look together."

The two men left the office and jogged all the way to the warehouse.

When they arrived at the warehouse, Section Chief Lu respectfully handed the drawings to Professor Wu.

But Professor Wu took it and handed it to Sun Zhengguo without even looking at it, and started chatting with the newly arrived Director Gao.

Professor Wu's action stunned everyone present. What was going on?

"Professor Wu, what are you doing?"

"Oh! Director Gao, it's my student who has the idea. Let him take a look first."

After hearing what Professor Wu said, Director Gao didn't know what to say.

You can't just ask, "Is your student good enough?" That would easily offend people, so you might as well wait.

Sun Zhengguo took the drawing, looked at it carefully for a while, and found a clue.

This machine was provided by Big Brother, who also had ulterior motives. The Russian instructions on it were ambiguous, and several of the internal gears had been tampered with. It was a castrated version for foreign trade.

This is exactly the same as what Sun Zhengguo guessed in his mind. In the past life, these foreigners had no good intentions. They made money from the Chinese while doing tricks. They have always been imperialists with the intention of destroying us.

Now that we know where the problem lies, the rest will be easy to solve, Sun Zhengguo handed the drawing to Professor Wu and said.

"Mr. Wu, I know what the problem is. Please come and take a look."

After Sun Zhengguo said this, except for Professor Wu and Chen Lianshan, the other leaders all showed expressions of care for mentally retarded children.

The engineers from the Ministry of Metallurgy have been studying this problem for two or three days but have not been able to figure it out.

You watched for a few minutes and you made a discovery. So you are making a fool of us?

However, Professor Wu didn't care about their expressions. Instead, he walked up quickly, took the drawing, and looked in the direction of Sun Zhengguo's finger.

Then the two of them talked in a low voice for a while, and Professor Wu confirmed that Sun Zhengguo had indeed found the problem, and that the problem was not difficult to solve.

"Great! Zhengguo, this problem is so deeply hidden, how did you find it?"

"Professor Wu, you know that I speak Russian very well. The Russian description on the blueprint is a bit far-fetched when it comes to this part. I later checked the blueprint again and found the problem. These foreign devils are really no good."

After listening to Sun Zhengguo's explanation, Professor Wu felt a little regretful. Why didn't such a good student want to stay?

"How is it? Professor Wu, have you found the problem?"

Director Gao noticed Professor Wu’s excited expression and quickly stepped forward to ask.

"Don't worry! Director Gao, my student has never let me down. You may not know that although my student has not graduated, he has participated in many mechanical modifications and has achieved impressive results."

Professor Wu also took the opportunity to promote Sun Zhengguo to prevent them from looking down on him.

"Then how should we cooperate?"

Seeing the credit right before his eyes, Director Gao quickly asked.

"Find your maintenance workers here and just follow my students' instructions."

"Quick, quick, quick, did you hear what Professor Wu said? Chief Lu, transfer all the maintenance team members here."

Following Director Gao's order, Section Chief Lu began to call for people, and within a short while, several maintenance workers in work clothes arrived.

"All of you, follow the instructions of this technician Sun. Do whatever he tells you to do."

"Don't worry! Director, I promise to follow your instructions."

Seeing that the personnel were in place, Sun Zhengguo did not hesitate to direct the workers to dismantle the machinery.

Half an hour passed in the blink of an eye. At this time, a large pile of parts had been placed on the felt cloth on the ground, and it seemed that the problem was about to occur.

But now a new problem arises. The workers have reached their limit when they dismantle the machinery to this point. If they dismantle it further, they don’t know how to start.

Seeing the workers' embarrassed expressions, Sun Zhengguo did not blame them, but picked up the tools himself and prepared to go on duty.

"Technician Sun, this...?"

Seeing Sun Zhengguo coming over with tools, the maintenance team leader said a little embarrassedly.

"Let me do it!"

Sure enough, after working as a maintenance worker for decades in my previous life, I finally found a place to put my skills to use.

After Sun Zhengguo took over, the dismantling work became much faster. After another ten minutes, they reached the problem area.

When Professor Wu and his companions saw this, they all quickly gathered around.

Sun Zhengguo gently removed several gears, then swapped them, and finally removed an extra gear and threw it aside. That was the end of the job.

"Mr. Wu, I have fulfilled my mission. Take another look. Do you have any other questions?"

The machine problem was solved. Sun Zhengguo put down the tools in his hands and said to Professor Wu beside him.

"I just saw a few gears being swapped, which should be fine, but why did you throw away a gear next to it?"

"Mr. Wu, I said these foreign devils have bad intentions. That gear is a redundant one. It has no effect and will affect the speed of the machine."

After listening to Sun Zhengguo's explanation, Professor Wu nodded. He believed in his students.

The factory leaders nearby looked like their father had died, with sad faces, but they didn't dare to say anything. It's a broken machine anyway, so you two can fix it as you please!

Sun Zhengguo did not need to do the following work. Several workers quickly assembled the machine. It took them about forty minutes to complete the reassembly. Then they added lubricating oil to the machine. Only then was the work completed.

"Gao Chang, the machine has been repaired now. Please ask your electrician to come over and connect the power! We need to test it."

"Okay! I'll go right away."

Without the factory director's instructions, Section Chief Lu volunteered and jogged away.

After a while, the electrician came and spent another ten minutes to connect the electricity.

Now everything is ready, just waiting to press the switch of the machine, and everyone becomes nervous in an instant.

"open it!"

Section Chief Lu received the order and carefully pressed the switch.

With a click, the whole machine started to move slowly, and finally faster and faster.

“Yeah…!”

"Bah bang bang...!"

First there was a shout of joy, followed by applause.

Although the machine has not been put into trial production, everyone knows that it has now been successfully repaired.

After all, everyone knew what the previous state was. It was completely broken and couldn't be started at all.
