The head teacher said so, and Lin Yifan naturally could only agree.

Anyway, he wasn't afraid of that Lin Fei.

……

"Teacher Xu is so close to Lin Yifan......"

"Too jealous......"

Seeing Xu Ruxuan talking so intimately in Lin Yifan's ear, many boys in the third (9th) class below immediately turned red.

In fact, Lin Yifan didn't know that Xu Ruxuan was a famous beauty teacher in the 13th High School, and she was also the goddess teacher of many boys in the third (9th) class of high school.

"Teacher Xu actually asked Lin Yifan to sit next to Lin Fei......"

"Didn't Lin Yifan fight with Lin Fei? Teacher Xu also asked Lin Yifan and Lin Fei to sit together......"

Immediately afterward, some people looked a little strange, while others were thoughtful.

……

"Lin Yifan, there are still several vacant seats in the class, why are you sitting here?"

Seeing Lin Yifan sitting next to him, Lin Fei said with an ugly face.

"I can't even look down on those positions, if you want to sit, go sit down!" Lin Yifan said lightly.

Although not all the students in the third (9th) class of high school come to class, the desks with masters show that there are masters.

Those who don't have the owner's vacant seats, the location is really not as good as this one.

If this Lin Fei really went to those vacant seats, he happened to occupy the vacant seats with a better position by himself, anyway, it was not him who drove Lin Fei away, and when the time came, Xu Ruxuan would have nothing to say.

Lin Yifan said secretly.

Lin Fei's face changed, and in the end, he still didn't go to those vacant seats.

Lin Fei had his own considerations, if he really went to those vacant seats, wouldn't it mean that he was afraid of Lin Yifan, and he was scared away by Lin Yifan?

In this case, he will lose face even more.

This is unacceptable to Lin Fei.

Soon, classes began.

The first class was Xu Ruxuan's class.

What Lin Yifan didn't expect was that Xu Ruxuan was not only the head teacher of the third (9) class of high school, but also the training teacher of the third (9) class of high school.

This class is a theory class, so none of the students in the third (9th) class of high school went to the practice room.

"More than 500 years ago, before the end of the world, there was a very popular saying that the brains of ordinary people were only 6 to 7 percent developed, and the rest was sleeping, and if a person's brain was developed to more than 10 percent, it was a super genius......"

On the podium, Xu Ruxuan preached in a very good voice.

But later, this statement was overturned, and the reason for the overturn is also ridiculous, because some people say that since more than 90% of the brain is sleeping, if this part of the sleeping brain is cut off, will this person still be able to live normally? It turns out that it is impossible to live normally, so those people are very decisive that this statement is wrong. ”

Xu Ruxuan smiled slightly and continued.

"Actually, the second statement is very wrong, even if more than 90% of a person's brain part is sleeping, then those sleeping brain parts must have a reason for sleeping, not using, does not mean that there is no need to exist, just like many high-tech items now, their performance, usually time, will not all play a role, but you can cut off all the properties that are not used? I'm sure that once the unused performance is cut, the normal performance of those high-tech items will be greatly affected, and even the entire item will collapse, which is also very normal. ”

"Of course, when I say this, I don't mean that the first statement is correct, in fact, the first statement is not true."

"The human brain, in fact, every part of the brain is being used normally."

It's just that some parts of them will be dormant when they are used, just like when a person uses his left hand, his right hand will subconsciously stop, and when some people use his right hand, his left hand will stop, and every part of the brain has its scope of work, and everyone's thinking is limited...... You can't mobilize all the parts of your brain at the same time! ”

Xu Ruxuan said slowly.

"According to scientists, the part of the brain that ordinary people can mobilize at the same time is about 6 to 7 percent...... Perhaps, this is the origin of the first statement! ”

"After the apocalypse, there are more mysterious energies between heaven and earth, and scientists have found that after human beings absorb these mysterious energies, not only will their physical fitness be greatly increased, but human brain cells can also grow, and the strength of brain cells is very important, so this theory has been mentioned again......

"At that time, some scientists suggested that ordinary people could only mobilize six to seven percent of their brain parts at the same time, so when a person can mobilize more brain parts, will his strength increase?"

"Some scientists have suggested that ordinary people can only mobilize six to seven percent of the brain at the same time, so when the strength of these brain cells that a person can mobilize becomes stronger, will the strength increase?"

"Later, these two theories were combined to form our current cultivation system!"

"These are the origins of our current cultivation system!"

"Before the realm of martial arts, all our training is to enhance the strength of each of our brain cells, and the data that the strength of these brain cells is finally transformed into is the so-called brain domain strength!"

"After the realm of martial arts, we must not only strengthen the strength of each brain cell, but also increase the part of the brain that we can mobilize at the same time!"

"Before the realm of martial arts, the number of brain cells of each person is limited and will not increase, next, I will tell you how to better enhance brain cells without damaging brain cells......

……

Lin Yifan listened carefully to Xu Ruxuan's lecture.

He found that Xu Ruxuan's lecture style was very different from Pang Long's lecture style.

Pang Long pursues every student's grades and every student's brain domain strength, while Xu Ruxuan is more considerate of students, so that students don't blindly pursue brain domain strength and damage their bodies, which Xu Ruxuan and Qi Ling said is very similar.

If a person blindly pursues the strength of the brain domain, the body will be damaged, and it may even affect the future impact of the martial arts realm.

At this point, he made a mistake, and Qi Ling made him take a lot of high-grade nutritional products before he could recover some of the dark wounds left in his body.

"It seems that this Xu Ruxuan is a good teacher......"

After a class, Lin Yifan sighed slightly and said.

In the whole class, what Xu Ruxuan talked about, what made Lin Yifan the most profound, was to think about students everywhere.

There are really not many such teachers.

"However, this kind of cultivation method is suitable for most people, but it is not suitable for me......" After a pause, in the depths of Lin Yifan's eyes, a glint flashed, and he said secretly.

Many people can't be promoted to the realm of martial artists in their lifetime, so the number of their brain cells, every time they die, they lose a part, unless there are powerful natural treasures, or special nutrients, the number of brain cells will not increase anymore.

In this way, if the brain cells are strong, they are powerful, and the disadvantages are also very obvious, which are obviously not as good as those with the same brain domain strength, but with a larger number of brain cells.

And he, if nothing else, can hit the realm of martial artists one hundred percent, once he hits the realm of martial arts and attracts the energy of heaven and earth, his brain cells will have a period of rapid growth, and all the brain cells that died before will re-divide out, and the final number will even increase.
