Li Xin ignored him and continued to repair the weapons on the workbench in silence.

A thick arm covered with black hair grabbed the weapon that Li Xin had repaired.

His loud voice began to rise again: "Idiot! New parts are free! And you just used them like this!"

He pointed at the replaced parts on the workbench and said, "How can this be used without repair? Why did you replace it with a new one?"

Li Xin turned his head to look at the person next to him. This was a middle-aged man. Due to the decline in his body functions, fat had accumulated in his stomach.

His legs are no longer there, but are replaced by relatively old mechanical prosthetics.

He is Li Xin's second uncle Li Zhuang, his raiser, and the first person Li Xin saw after traveling through time and space as a baby in this era.

At this time, Li Zhuang was frowning tightly and looking at Li Xin with disgust, as if he had done something unforgivable.

Li Xin took the replaced parts in his hand and said, "It's okay, you can fix these parts to be 99% new anyway!"

"You're useless! I don't know how you even graduated!"

"Don't go to the company as soon as possible, or they will scold you to death!"

"I have to do this little chore! Why don't you train with me for a few more years?"

Li Zhuang's face looked very ugly. He pushed Li Xin away and started working on the workbench.

Seeing this, Li Xin didn't say anything more. He had long been accustomed to such an attitude.

He cleaned the oil off his hands, picked up a tube of energy paste, opened it skillfully, and then squeezed the energy paste into his mouth.

Energy paste is the most common food consumed by people living on Guansuo 4. It usually has no taste, only a strong industrial smell.

But people have no choice. Although it has no taste, it already has all the consumption needed to sustain survival.

If you eat it frequently, people like Li Zhuang whose physical functions decline may even have fat accumulation. One tube of it can equal an adult's daily consumption. You can imagine the energy contained in it.

Li Xin finished eating the energy paste in the plastic package and squeezed it clean before he stopped.

"Clatter!" The rolling shutter door of the repair shop was slammed.

"Is anyone there? Open the door!"

"Here they come! Why are you knocking so early in the morning? Are you calling back the souls?" Li Zhuang shouted out words full of resentment in his hoarse voice.

But he still obediently opened the shutter door, and then squinted at the two people outside the door in the dim light.

Outside the door.

A middle-aged man in uniform also squinted slightly. He also wore glasses and said:

"I'm here to look for Li Xin. Does he live here?"
