Thinking of this, Lin Hai left a sentence, "Test it with existing materials first, do a good job, I still have high hopes for you." and left Laboratory No. 2.

Yes, no matter what, the project must be carried out, so encouragement before leaving will be very helpful in boosting morale. This can be regarded as the "knowledge" that Lin Hai brought from his previous life.

But no matter what, at least in the short term, forget about the cannon.

After leaving Laboratory No. 2, Lin Hai took Shi Zhener and went straight to Laboratory No. 1.

I have to hear some good news today no matter what.

And there was really good news from Laboratory No. 1. After all, they had asked Lin Hai to check out their progress a few days ago, and said that there had been "great progress", which made Lin Hai very pleased.

Waiting at the door of Laboratory No. 1 was He Chun, wearing a custom-made Qinghe research suit. She was also one of the first graduates of Linhai Night School.

Lin Hai still remembers the night when the first batch of twelve students graduated. Lin Hai had a serious talk with each student. There was actually only one topic of conversation, which was "the future."

Lin Hai carefully told the twelve students the plan he could describe, hoping that they could find the part that interested them.

This is why, although the twelve people are classmates, they each chose completely different directions.

Lin Hai still remembers that He Chun was not the smartest or most daring student. No matter what he did, he would never be the first to do it, and of course he would not be the last one either. He always kept himself in the crowd and looked inconspicuous.

The conversation that left the deepest impression on Lin Hai was that of He Chun.

Since he had no idea of ​​He Chun's true thoughts, Lin Hai actually prepared a lot of lines of speech, hoping to arouse her interest. If that still didn't work, he would even send her to work in logistics or the art troupe, as she couldn't be wasted anyway. That was Lin Hai's true thought.

But everything was different from what Lin Hai expected.

The first thing He Chun said after entering was, "Principal, you mentioned in class that lightning is electricity, and friction also generates electricity. We can't actually use this electricity, but there are other ways to produce electricity for us to use. Is that true?"

Only then did Lin Hai recall the few words he had casually mentioned during class.

"It does exist. But it's very troublesome. I originally planned to study it myself once we had developed to a certain level. What, are you interested?"

"You know, I have been afraid of the dark since I was a child. When you found me in the old forest, I thought you were a bad guy and wanted to escape, but the forest was too dark. I didn't dare to go in, so I stayed at the edge of the forest and didn't dare to move." He Chun spoke very slowly, just like when Lin Hai had just found her.

"Oh, I remember now. I thought you were very brave at that time for not running away. You know, I was with a group of strong men at that time, wearing armor and holding knives. We were not good people at all. Most people would run away when they saw us, but you were waiting for us outside the woods." Lin Hai said with a smile.

In fact, this was also the reason why he chose He Chun as one of his first students. Lin Hai still remembers that he wrote in He Chun's night school file: "This student is bold and careful, independent and capable of great use."

For a long time afterwards, Lin Hai thought he had made a mistake, but he didn't expect it to be this reason.

"You said that if we could generate electricity, it would generate light and illuminate the night like day. Is that true?"

“That’s true, but He Chun, I want to tell you that other people’s choices, whether it’s medicine, military affairs, internal affairs, or smelting... we all have corresponding foundations, and they can develop and flourish on these foundations.

But the path you chose is different. Before you knew the concept of electricity, I was probably the only one in the world who understood it. Of course, things like lightning don't count. If you want to study it, it's not like building a skyscraper from scratch; you have to dig the foundation yourself.

It’s going to be difficult.”

"I know, but Principal, I want to study electricity."

Lin Hai asked three times in a row, and He Chun confirmed three times in a row.

Lin Hai looked at He Chun's determined face and finally said, "Okay, I hope you can use electricity to emit light and heat, and illuminate the world with warmth in the future."

"Then the first concept I want to tell you is 'magnetoelectricity'."
