After traveling through time, I, as a mechanical genius, am dedicated to improving myself.

He took out the toolbox from under the bed and disassembled the radio again to see how to modify it. After the modification, he would give it to Jiang Cai. He had to show some skills so that they would be willing to spend a lot of money to "train" him.

In this day and age, the control over parts and other things is too strict. Apart from relying on the state, it is difficult to have other ways out in the field of technology.

After dinner, Zeng Li still took a long time to finish it.

Due to limited conditions, the difference after the renovation is quite big, but it does not meet Zeng Li's expectations, so I have to make do with it.

After the first experience, I sneaked into my parents' room and took out their radio to modify it.

After making the changes, he forgot to put it back. The next day, Shuyi couldn't find the radio. He was very puzzled. He searched his own room and went to Zeng Nantian's room to look. Finally, when he couldn't find it anywhere else, he went to Zeng Li's room.

As soon as I opened the door, I saw my radio on the table.

He glanced at the toolbox that had been used but not put away.

"Is this what Lili likes to play recently?"

I picked up the radio and found it had become lighter.

"This kid, will he tear my radio apart and break it?"

At this moment, Zeng Li knocked on the door of the principal's office.

"Principal, could you please call Mr. Jiang from the National University of Defense Technology yesterday? Give him this radio."

The principal stood up and said, "I can, but why are you so young giving gifts? If you want to give, then give it. And give a second-hand one."

"Zeng Li, you might not know that other schools might be easier to get into if you use connections or something, but that's not the case with the National University of Defense Technology. It's very strict."

Zeng Li explained, "I'm using it myself. I modified it to show him what I can do."

After saying that, he put down the radio and went to class.

The principal looked at Zeng Li's back and felt itchy. "Can I see your skills first? What do you want to change it to?"

There happens to be a radio in the office, so I'll compare it and see what the difference is after Zeng Li's modification.

Zeng Li had just sat down when Ma Dai came over again.

"Why are you carrying a radio to school? Where's the radio? I saw you enter the school gate, but how come you arrived in the classroom so much later than me?"

Zeng Li changed the subject: "Is the glutinous rice cake delicious this morning?"

Ma Dai subconsciously covered his mouth: "How do you know?"

"There are still traces of unwiped corners of your mouth."

Ma Dai touched the corner of his mouth: No.

The topic was diverted and Ma Dai didn't even remember the previous question.

Jiang Cai was staying in the largest hotel in the city and had just returned from exercising when he received the call.

The principal specifically explained that it was not a gift, but a modified radio for him to see.

Jiang just remembered the scene of the father and daughter getting along yesterday. It didn't seem like they would be smart enough to give gifts, and her mother was against it, so it was even more impossible for them to prepare gifts.

I took a shower, changed my clothes and went to school.

The principal weighed his own radio against the one Zeng Li had given him and found that the latter was much lighter.

I didn't dare to mess with anything else, for fear of ruining something that would affect Zeng Li.

When Jiang arrived, the principal's first words were, "Feel it, it's much lighter. I didn't dare touch anything else. I was waiting for you to come so we could study it together."

Jiang Cai didn't expose him because he was afraid that if he took the radio away, he wouldn't be able to study it.

Jiang Cai carried it on both sides for comparison, and it was one third lighter.

Open at the same time.

The principal's phone was still rustling, but Zeng Li could already clearly hear the announcement.

Jiang Cai turned off the principal's radio and moved it further away so that he could hear the sound quality of Zeng Li's radio more clearly.

There are many more channels, and you can hear foreign languages, but they don’t sound like English, so Jiang couldn’t understand them.

"Can you call Zeng Li over now?"

The principal was also shocked. After coming to his senses, he went to Zeng Li's classroom to look for someone.

The head teacher was still teaching when the principal rushed in and took Zeng Li away.

"Come on, Zeng Li, Teacher Jiang can't figure out your radio."

The students watched Zeng Li being dragged away by the principal.

The head teacher paused for a moment and continued the class.
