"You still don't have to worry about me, you still have to worry about next week's exam, you know, three consecutive classes are dozens of parents to invite parents, you have already done it twice!" Li Nan leaned into his ear and said faintly.

"Don't tell me this, you school, and I'm not afraid even if I invite my parents, my dad definitely won't have the time to come, my mother's words, at most, I will sulk for a while, and it will be fine in a few days." Wang Dang was very complacent.

"Some students, with bad grades, sit below and mess around, disturbing the study of other students' good students, what kind of mentality is this kind of person?

I won't name who it is, but I'll pay attention. The math teacher's voice suddenly rose a little.

Wang Dang didn't care, rolled his eyes and stopped talking.

Li Nan looked at him a little thoughtfully, in the end, the big guys are all scumbags together, although they didn't scumbag to the same extent when they were the most scumbag, but the two have also been at the same table for more than a year, and the relationship is quite good, since they have the ability, it should be nothing to do a favor.

Li Nan has a medicine in his hand that can make people smarter, this medicine is a brain domain development medicine, which itself will not change the individual's genes, but will only make the individual's brain better, and the memory and other aspects will be slightly improved.

It's just that this medicine is a medicine that forcibly improves the brain domain, so the use process is very painful, and the specific pain level is probably about the same as the pain level of eating monkey brain alive. Of course, this is not talking about people who eat monkey brains, but about monkeys who are eaten monkey brains.

If Li Nan didn't want to expose himself, he could only secretly drug him. But this medicine is an injectable drug, and it is really a bit difficult to do it without knowing it.

In the end, he thought about it for a while, and then he came up with a solution, that is, to sneak to his house at night with an invisibility charm, and then give him a dose of analgesics and inject brain domain development drugs, although it will be painful at that time, it should not be so painful that he wants to commit suicide.

As for whether their family would think that Wang Dang had an undiagnosed disease, Li Nan couldn't think about it, how could there be anything perfect in the world?

"Although he didn't agree to this matter, if he could become smarter and improve his academic performance to make his father happy, Wang Dang should be willing!"

Li Nan privately felt that this idea should be no problem, don't look at Wang Dangcheng's heartlessness, and he doesn't seem to study much, but in fact, he will work indirectly for a period of time in private. It's just that he succumbs to the IQ problem, and he himself doesn't like to listen to the tutor's lectures, so it's hard to improve.

A lot happened on Friday night, Li Tong ate a stomach full of fruit at home, ate diarrhea, and never came out of the toilet. Li Nan sneaked to Wang Dang's house, knocked Wang Dang unconscious, and injected him with medicine. Li Ji thought that Ji Juan would not come back this week, so he did not go home, and he was still living at the school.

The affairs of the Li family are actually trivial, and Wang Dang's family is about to fall into trouble.

That night, when Wang Dang's father and his mother came home together, they did not see their son playing games in the bedroom or doing his homework.

What I saw was Wang Dang rolling around in the living room in pain, holding his head and constantly hitting the sofa, and sometimes accidentally hitting some solid wooden layers.

"What's going on, are you stupid? Hurry up and report it...... Phew, hurry up and call the hospital!" Chen Xue (Wang Dang's mother) was so anxious that she almost said the wrong thing, and hurriedly roared at her husband, and ran over to hug Wang Dang and stop him from harming himself.

When Wang Gang saw this situation, he was also panicked, and he took out his mobile phone at a loss, and called the hospital with trembling fingers.

"Hello, this is the County People's Hospital, what is the matter with you?"

"I ...... My son suddenly went crazy at home, constantly banging his head against the wall, looking very painful, you guys come over there, hurry up and help me see my son!" Wang Gang hurriedly said.

After that, the hospital changed the phone: "Hello, I just heard what you said, this situation is likely to be epilepsy, of course, it may also be other symptoms, this is currently not seen patients, we can't be sure."

But if you want to keep your son under control for a while, be sure to plug his mouth with something so that he doesn't bite his tongue in pain. In addition, please quickly report your address, and we will send someone there. ”

"Oh okay, we're at home...... You have to hurry up, my son, he is really ...... this situation" Wang Gang said anxiously, while quickly running to the changing room to find a towel and plugging Wang Dang's mouth.

"That's the matter, what the hell is going on!" Chen Xue was almost distressed to death, Wang Dang, who was gagged, kept struggling, and in the process of struggling, tears were still flowing from the corners of his eyes, which were painful tears.

The previous analgesic could only relieve pain for a quarter of an hour, but it took more than an hour for the brain to develop the drug, which meant that it would hurt for more than two hours.

The hospital also received the news very quickly, but when the diagnosis was confirmed, everyone was very confused.

"It's not epilepsy, it's not anything epilepsy-related, it's not even neurological!

Looking at this EEG, it seems that his brain waves are fluctuating sharply, and the frequency of fluctuations is much higher than that of a normal person, of course I am not saying that he is mentally ill.

I mean, the inside of his brain seems to have been hit to a great extent, and I can't say the specifics, because I've never seen this type of patient!"

Although sedatives and analgesics were able to relieve his pain, neither of them had a long onset of action and should not be used aggressively, and too much use could cause irreparable damage to the nervous system.

"It's also too strange, their family has no genetic history, and his previous physical condition was also very healthy, but he was very inexplicably ill.

The whole body has been checked, there is nothing wrong with it, and even the physical condition is much healthier than the average person, and there is no sub-health state like ordinary middle school students!" The remaining doctors checked his examination report and also had a headache.

The whole body was examined from the head to the blood, and no problem was found.

Now it seems that the main problem should be in the head, but they have not studied the brain very deeply, and they only know a rough idea of many problems.
