"Alas, I won't play with you anymore, I haven't studied today, I'll go home first, and come back in the evening, if it's okay, I'll withdraw first." Lim Seung-jae saw that the time was almost up, and the wallet had been taken back, so it was time to do something serious.

Taeyeon just pouted, "Get out, get out, for the sake of you taking us to pick up the car today, I'll reluctantly forgive you." ”

Lim Seung-jae now spends at least four to five hours a day researching and studying, and although he doesn't necessarily go to school, he will stick to it at home.

……

"The charging speed can be reduced, and the super battery can last for at least ......ten years according to the current situation," Lim Seung-jae drew some patterns that normal people couldn't understand on a large pile of white paper, and there were dense formulas written on them, all of which were used for calculations.

There are chemical and physical ......

Lin Seungjae can almost be said to be an all-rounder in learning, basically as long as he has the heart to learn something, there is nothing he can't learn.

"Theoretically, ten minutes to be full, should not be a big problem, but in terms of voltage requirements...... "Now the charging pile under construction in the country also takes nearly half an hour to fully charge a battery, and this ultra-fast charging also has a certain amount of damage to the battery itself."

The life of a battery, in Lin Chengzai's calculations, should only be able to last for seven to eight years at most, and the actual use, five years is already the limit, although this time is very long, but Lin Chengzai is still not satisfied, there is still room for improvement.

So Lim Seung-jae plans to increase the development of batteries.

"Not bad, so be it for now."

In Lim Seung-jae's research, four hours passed before he knew it, and there were mountains of paper around him. It is all written full, and there is almost no room for it, so to speak, every piece of paper written by Lin Seungjae is wealth for those who have a heart!

"That's the case. The charging speed should be increased by another 15 percent, and the volume can be concentrated by 10 percent......"

"OPPA~~~ Are you okay, I've been waiting for almost half an hour, when are you going to graffiti!" After Sun Naen's child 'got off work', she came directly to the next door, wanting to find Lin Seungjae to make up for her, but she saw that he had been writing things that she couldn't understand at all.

Of course, she didn't know that it was some esoteric formula, but because she really couldn't understand it. So her evaluation of this thing is 'graffiti'!

Nan Eun is a sensible girl and will not disturb Lim Seung-jae when he is working, but seeing that he has finally stopped, she can't help it anymore.

"Yo, I thought you'd hold back." Lin Seungjae loosened his muscles, "What's wrong?" Can I help you? ”

"OPPA, you're playing stupid again. Tomorrow is my birthday! Said you were going to give me a gift! And you haven't helped me with my classes for a long time, and my academic performance has dropped recently. Don't you think you should compensate me a bit? Sun Naen pouted.

Since having Lin Chengzai, a 'special teacher' by his side, Sun Naen has not only improved his academic performance, but also his enthusiasm for learning. However, in Lim Seung-jae's body, she doesn't seem to be able to find anything that can stump this man at all.

Gradually, she seemed to be infected, and her learning efficiency also improved a lot.

What academic performance has dropped, it is all made up by her. Now Son Na-eun's grades are good, as long as she can persist like this, at least relying on her own strength, there is no problem at all in being admitted to Sungkyunkwan or anything, and even Seoul National University has a certain hope.

"What kind of class to make, really, I have already taught you how to study, now it's up to you, as long as you can persevere, maybe I can really see you at Seoul National University in the future."

"I'll lend you good words, so, OPPA, you know......"

Sun Naen stretched out her hand cutely, and her two white palms were spread out in front of Lin Chengzai like this, with a cute expression, "What about my gift?" ”

"What's the hurry, isn't it a birthday yet? I'll give it to you tomorrow. "The gift for Sun Na-eun, Lim Seung-jae had already bought it when he was in Osaka, although he didn't know what Na-eun liked, but he believed that she should like this gift.

Sun Naen pouted, "Okay, then OPPA, you accompany me to play while Ernie hasn't come back yet." ”

"Why didn't Chu Long come back?" Lim Seung-jae expressed puzzlement.

"Because I don't want to be beaten yet, although Chu Long Oni doesn't say it, in fact, as long as we get close to you, she will be jealous, don't you know her ......" Sun Naen also felt that in the recent period, Lin Seungjae and Jessica and Yuna have been too close, and they have ignored Chu Long a little, so they are also a little upset for her.

Lim Seung-jae heard what Nan said and smiled, "What's wrong?" If you have anything to say, just say it, I'm not an outsider. ”

"I can't hold it back, there are some things that you must know OPPA."

Although Sun Naen is not very smart, she is really a very careful girl, and unlike the careless Chu Long, she can find many details that ordinary people can't find.

Like Chu Long will be jealous, the whole combination, she can see it alone.

Nan En pulled her clothes and walked out directly, her eyes were a little blank, but she couldn't stand it anymore, "OPPA, do you know, in fact, Chu Long Oni she really likes it, she likes you very, very much, I think you should spend more time on her and care about her......"

"Huh? How so? Lim Seung-jae put away his smile and showed a serious look.

"I've never seen Chu Long Oni staring at a photo of a person in a daze, you're the only one." Sun Naen measured her face and looked at Lin Seungjae, "Chu Long Oni, she ......"

As she spoke, Nan began to struggle again, and Chu Long asked her not to say it, but she really couldn't hold it back.

"I can't say it, I don't want to hear it." Lin Chengzai interrupted the tangled Nan En with a smile, there are some things, Lin Chengjae doesn't know, but he just doesn't know how to say it, "Actually, if you don't say it, I also know that Chu Long's stupid girl always likes to be strong, and when she encounters things, she just buries herself silently in her heart, she really loves to cry." ”

Sun Naen was stunned, she thought that Lin Seungjae should not know, "OPPA, you know everything?" ”

"I was careless last time...... See. ”

Lin Chengzai raised his head a little sadly, Chu Long is a very distressing girl, she likes a person, she can't express it in words, she will only silently use her own actions and her own good to let the other party know.

Fortunately, the person she likes is not too slow, and of course, she is not lucky, because what she likes is a big fool who is emotionally indecisive.

"Chu Long Oni, in fact, is very fragile, OPPA, you have to be kind to her." Sun Na-eun is also a little upset for Park Chu-long, in her opinion, Chu-long is really good to Lim Seung-jae, and the good is a bit too much.

Even, sometimes, she thinks that Lin Chengjae is not equal to Chu Long's entire world!

When chatting, he always pulls the topic to Lin Seungjae for some reason, although in front of him, he never says it, but ......

All they heard was his good!

In Chu Long's mouth, although he seemed to be complaining about Lin Chengjae's shortcomings, they onlookers could easily hear Chu Long's attachment to Lin Chengjae from it. It's not so much complaining about Lin Seungjae's shortcomings, but praising his advantages.

What you hear from the mouth of the third person is sometimes more real than what you see.

Because it is not subjective, in Nan's eyes, Chu Long has already paid everything she can for Lin Chengjae, and these days, Nan is seeing it in her eyes and hurting in her heart. (To be continued......)
