1952: Walking through Nantongluo Alley

In this way, Chen Xiao rode the bicycle and Sha Zhu ran beside him.

It's true, this kid Sha Zhu has great endurance. He walked several miles from the courtyard to the steel mill without even taking a breath.

As soon as the two of them arrived at the gate of the steel mill and looked at the densely packed workers, Chen Xiao knew that he was about to start a life of hard work.

At this time, a young and pretty figure appeared at the door of the steel rolling mill. Her appearance attracted the men of all ages around to stop and take a peek.

It was Liu Lan, the woman who worked in the kitchen of the steel mill and who had affairs with many men in the TV series.

Even the original owner was deeply impressed by her.

Now Jia Dongxu is not dead yet, and Qin Huairu has not gone to work in the steel rolling mill according to the story line of the TV series, so the current factory beauty belongs to Liu Lan.

I glanced back and found that Sha Zhu was stunned.

Chen Xiao called him twice.

"Silly Zhu! Silly Zhu! What are you doing?"

"Ah?" Sha Zhu was confused, and his eyes had just moved away from Liu Lan.

The next moment his face suddenly turned red.

Chen Xiao immediately understood Sha Zhu's cunning intentions and said to her with a wicked smile.

"Are you interested in Liu Lan?"

Sha Zhu's face suddenly turned red. He squatted down, covered his face and shouted.

"I didn't... I didn't... Brother Chen Xiao, I didn't..."

This scene gave Chen Xiao a sense of déjà vu?

Silly Zhu? Dasha Chun?

The two of them actually have some similarities.

"You don't have any, right? If you don't have any, then I'm leaving and going back to work in the workshop."

Sha Zhu stood up from the ground and said with a red face.

"Brother Chen Xiao, I really didn't do anything. You won't tell others nonsense, right?"

"Sister Liu Lan is already engaged. I heard she's getting married soon. I'm three years younger than her. Brother Chen Xiao, please don't talk nonsense in the steel mill."

Chen Xiao was too lazy to listen to Sha Zhu's excuses and pushed his bicycle towards the carport.

Although he wanted to take Sha Zhu as his apprentice, how could he help her chase women? Besides, wouldn't it be better for him to keep the fun to himself?

Chen Xiao worked in the No. 2 machinist workshop at the steel rolling mill, where he worked alongside some of his old acquaintances from the courtyard: Yi Zhonghai, a seventh-level machinist, Liu Haizhong, a sixth-level machinist, and Jia Dongxu, who was also an apprentice.

When I came to the workshop and looked at the six-foot belt lathes in the workshop, I couldn't help feeling emotional.

The six-foot belt lathe laid the foundation for the development history of my country's machine tools. It is an important milestone and witnessed the development process of my country's machine tools from scratch.

Since the establishment of Shenyang No. 49 Machine Tool Factory in , it has quickly spread throughout the country in just two years.

Although Chen Xiao doesn't understand machine tools, he has read a lot of knowledge related to machine tools.

At this time, the old craftsmen in the workshop have begun to debug the machine tools to prepare for a new day's work.

As an apprentice, Chen Xiao followed the master and spent most of his time helping him load and unload materials.

Chen Xiao picked up the drawing on the workbench and looked at it carefully.

The drawing shows a 7.62mm internal spiral tube, densely packed with various process requirements and dimensions.

Seeing this scene, Chen Xiao recalled the history of 1953.

During the Korean War, my country purchased a batch of weapons and equipment from the Soviet Union that was enough to equip three divisions. Most of these weapons were old weapons that had been eliminated by the Soviet Union, such as the Mosin-Nagant 30, 38 and 44 rifles.

Most people think that my country's first rifle is the Type 56 semi-automatic rifle.

其实在56式半自动步枪之前还有一个53式，只不过没有56式名气大，服役时间长。53式在1953年研发成功，并在1954年开始列装部队。

If Chen Xiao guessed correctly, the 7.62mm internal threaded tube in front of him should be the one used on the Type 53 semi-automatic rifle.

At this time, a mocking laugh appeared beside Chen Xiao.

"You're the only one holding the blueprint and looking at it. Can you understand it?"

Chen Xiao looked up and found that it was the brat Jia Dongxu.

"What's your business whether I understand or not? If you want a fight, just say so."

Jia Dongxu was stunned for a moment, then burst into laughter.

"Chen Xiao, do you think we're still in the courtyard? This is Workshop No. 2 of the steel mill. My master, Yi Zhonghai, is one of only two level seven fitters in the entire mill, and I'm the one who's making the most progress among all the apprentices there."

"Tell me, what can you compare with me?"

Chen Xiao rolled his eyes at him and said calmly.

"Stupid!"

Then he ignored Jia Dongxu, put the drawings on the table, stood behind the master and began to watch and learn.

"You! You! You!" Jia Dongxu's face turned red.

He originally wanted to compete with Chen Xiao with his skills and then humiliate him.

Unexpectedly, Chen Xiao didn't buy it at all.

"What do you mean by 'you'? Do you have nothing to do, or do you want to patrol the workshop like the workshop director? Can't you just follow the master and learn the skills seriously like me?"

After Chen Xiao said this, the old master operating the machine tool nearby chuckled.

They had always disliked Jia Dongxu, who relied on his master being Yi Zhonghai to act lawless in the workshop.

Now that I see him being humiliated, I am naturally very happy.

Listening to the mocking voices around him, Jia Dongxu's self-esteem was greatly insulted.

Yi Zhonghai saw the situation here and shouted at Jia Dongxu with a dark face.

"Dongxu, come back quickly."

"I understand, Master." Jia Dongxu replied, then looked at Chen Xiao.

At this time, a leader appeared at the door of the workshop.

"Masters, please stop what you are doing and let's hold a small meeting."

After hearing this, the workers in the workshop put down their work and walked towards the leader.

The leader started speaking only after he saw that most of the workers had arrived.

"Masters, have you all seen the drawings of the workbench just now?"

Everyone nodded and looked at each other.

Although they have all seen the drawings, it is still a bit difficult to make them.

The main reason is that they have never made internal threaded pipes before, and the process requirements are a bit high. Not only must the diameter, depth, spacing, and angle of the thread be within the tolerance.

And the most crucial thing is the cutting tools. If we don't give them cutting tools, are we going to let them make them themselves? This thing needs a cutting tool with a hardness of at least 50.

This is really too difficult for them.

The leader continued.

"I know this 7.62mm internal threaded pipe is a bit difficult for you, but our country is least afraid of difficulty."

"If the Russians can do it, why can't we? We are all human beings, and we are no less than them."

The leader first gave some encouragement, and then asked Yi Zhonghai, who had the best locksmith skills among the people present.

"Master Yi, if you have the tools, how long would it take you to make this 7.62mm internally threaded pipe?"
