Invincible Super System Modifier

As the old man spoke, he took the lead and walked over.    

Lin Fei and the young girl immediately followed.    

"What's the matter?" The old man's friend was very cold. He said, "You have disturbed my research."    

"You are already old, what is there to study about?" The old man smiled faintly and said, "Today, I'm not looking for you, but these two young people."    

"Why are you looking for me?" Old Man Zhang looked at Lin Fei and the young girl again.    

"I heard you can make Conveyor." Lin Fei also became serious. "So I want to trouble you..."    

In the end, before Lin Fei could finish, he interrupted him and said, "I'm not free. You guys can leave and disturb my research."    

After saying that, he turned around and prepared to return to the house.    

Lin Fei was not angry, because he had been prepared to be rejected from the beginning. In this post-apocalyptic world, who would help others for no reason?    

In the end, the old man beside Lin Fei suddenly said, "Wait for a moment."    

"What?"    

Old Man Zhang looked impatient.    

"I like this kid. So what if you help him?"    

He said, "What research are you doing? Let this kid help you. Later, you can get him another Conveyor. What do you think?"    

Lin Fei's gaze immediately fell on the old man.    

He never thought that this old man would actually speak up for him at this moment. Initially, he thought that this old man would laugh at him.    

To be honest, Lin Fei felt a little touched in his heart.    

However, in fact, this old man only wanted to see the scene of Lin Fei being ordered around. It must be very funny. When the time came, he would lend a helping hand and make Lin Fei his disciple.    

It was a perfect plan!    

Old Man Zhang stopped and turned around to look at Lin Fei. He was silent for a moment.    

Then he said, "I do have something that I need your help with. If you help me solve it, I will help you create the Conveyor."    

Lin Fei looked at Old Man Zhang and said, "What is it?"    

Old Man Zhang said, "The thing I am making is missing some important parts. I need you to help me find them."    

"Do you know where it is?" Lin Fei asked.    

"I'll give you a map." Old Man Zhang took out a palm-sized board, and with a flip of his hand, he drew out a map.    

It was the map of the entire F City.    

There were also many things marked on it, such as where there was food, where there were water resources, and where there was a factory...    

There were a few places marked in red.    

In the middle, there was a blue arrowhead, which was the exact location of the board.    

"I've marked it all, go to these places and bring it back" Old Man Zhang said.    

He pointed to the place marked red. There was something important written on the side.    

Lin Fei took the board and asked, "If I collect all the materials for you today, how long will it take for you to make Conveyor for me?"    

Old Man Zhang said, "Within three days."    

"Yes, you can."    

This speed was considered fast, within Lin Fei's acceptable range.    

It wasn't a big deal to help him get some materials, because from the very beginning, he had never thought of doing it for free.    

He brought the young girl and left.    

The old man saw the two of them leave and immediately smiled: "Why didn't you tell them clearly that there were S-class monsters in that factory?"    

"If you want something, you have to give up something. There is no free lunch in this world." Old Man Zhang said, "Furthermore, what I am researching now is the latest and strongest Conveyor."    

"If he helps me complete it, this Conveyor will be his."
