Hearing Ichiro Kudo's words, Haruki Koike and Ryoya Kato came over to take a look.

What catches my eye is a function problem.

Knowing that the function f(x) is an odd function and is an increasing function on (-∞,+∞), if x,y satisfies the equation f(2x2-4x)+f(y)=0, then the maximum value of 4x+y is ____

The two people who came over were also confused, and they could understand the words, but when they were connected to the symbols, they couldn't understand them.

Koike Haruki said helplessly, "Ichiro, I advise you to tell the truth to your seniors." When we were in middle school, we didn't study at all, and our knowledge level was at the national level, which was obviously a high school topic. I can't understand it, how to do it? ”

Ryoya Kato also nodded and persuaded, "Don't die to save face, I heard that the tail of the first (3rd) class of high school is still at the elementary school level." And I heard from the seniors of the Fengjian Department that if you don't reach the average score of the grade in each monthly exam, there will be punishment. ”

Ichiro Kudo still wanted to refute it, but when he heard the punishment, the whole person withered.

"The answer to this question is 8."

While the three of them were talking, a voice like a trickle of spring water suddenly came from the side. As soon as the three of them turned their heads, they saw a mature and beautiful woman, and they stood on the spot all of a sudden.

However, they all reacted quickly, and Nagayama China's temperament was outstanding and dignified, which made them feel restrained as students.

Seeing this, Nagayama China smiled gently, "Hello classmates, can I ask you a few questions?" ”

After a slight hesitation, all three nodded slightly.

The question that Nagayama China wants to ask is naturally the matter here in the heart of the tree. She thought that after so many years, Shuxin Lake would develop into a holy place for love, but she would never have thought that a group of boys would study here.

Although the scenery here is very good, it is a great pleasure to study here. But this is completely different from what she imagined! If my sister knows about this place in the spirit of heaven, I don't know if I am relieved or crying or laughing.

However, it is naturally a good thing that Sakuraku's students can take the initiative to learn. For preconceived reasons, she thought that the school was full of bad students, but she didn't expect to be surprised as soon as she entered the school.

Regarding Nagayama China's question, the three Kudo Ichiro naturally answered truthfully.

Things here are no secrets.

Tree Heart Lake was indeed a holy place for love before, but after this place was discovered by a few members of the Fengjian Sect before, they liked the scenery here, and they liked to study here every time they took a lunch break or afternoon after school.

And people who are in love, looking at the members of the Fengjian Department who are studying next to them, always feel out of place. Over time, this place became the exclusive domain of the Fengjian Division.

Tree Heart Lake has changed from a holy place of love to a holy place of learning. Some ordinary students who like to read will come over if they have nothing to do, after all, the members of the Fengjian Department who love to study don't look so scary. And if there is anything you don't understand, you can ask each other questions.

Some of the top students will eat here during their lunch break, discuss study problems, and by the way, they are also enthusiastic to answer the questions of some poor students in the Fengjian Department.

It has developed to the present, and it has become what it is now, and the entire perimeter of the Tree Heart Lake is surrounded by students.

Nagayama China was surprised in her heart, this Fengjian Department is too terrifying, a club has affected the entire school, doesn't it mean that Sakura Jiu is a lot worse? There are so many people studying in this place, don't those bad people come to find trouble?

According to Nagayama China's thoughts, if Sakuraku's bad boy knew that there were so many people studying here, he would probably pull a lot of companions to collect protection money, right?

When this question was raised by Nagayama China, the three of Kudo Ichiro looked at Nagayama China with strange eyes, "Don't you know that the Fengkenbu is the biggest bad group in Sakuraku?" ”

"What?" China Nagayama was shocked in her heart, bad teenagers study collectively, isn't this a joke? She had a sense of doubt about life.

Seeing China Nagayama's surprised look, as if he knew what the other party was thinking, Kudo Ichiro suddenly felt unhappy in his heart, and said directly, "Sakuraku-kun school is so good now, it's all the credit of Minister Kimura. The Fengjian Department was established by him, and if there is no minister, it is estimated that you will be charged protection money when you enter the school. ”

Although he has been scolding Kimura Kazuki in his heart for the past few days, in fact, Kudo Ichiro also knows that Kimura Kazuki is indeed good for everyone. He's just rebellious, not stupid.

Since he learned that many of the seniors who graduated from the Fengjian Department were admitted to the universities of his choice, he was also determined to study hard. He thought about it when he was in middle school, but he didn't stick to it.

Now, if he doesn't study well, he'll be punished. Coupled with the supervision and guidance of the seniors of the Fengjian Department, he has a strong motivation to learn.

Minister Kimura? It must be Kazuki Kimura.

Nagayama didn't ask, because she could feel that the three students in front of her seemed to be unfriendly to her.

As for Kimura and Kazuki, Nagayama China only had a cursory understanding before coming. Knowing that the other party is Sakuraku's biggest bad, all schools in Imabun District have a strong deterrent effect.

Before, she actually didn't want Kimura and Shu to be Haruka's tutors. Because the other party is a bad boy, who knows if the other party will do something crazy.

But now that I see it, I seem to have misunderstood?

China Nagayama didn't actually misunderstand, and the information she got wasn't wrong. But that's all the impression that students from other schools have of Kimura Kazuki, and now because Sakuraku's school gate can't enter and exit at will, students from other schools don't dare to come over. Naturally, I don't know much about the current Sakuraku, and the information she got was a long time ago.

For example, before Ichiro Kudo entered the school, he thought that Sakurakuyu was still a bad concentration camp. Only sisters like Furubashi who live not far from the school will know something.

And a year ago, Kazuki Kimura had just entered Sakuraku, and he was indeed very brutal, and almost everyone who provoked him was sent to the hospital by him.

More than half a year ago, he knew that if he let Kurokawa Kaito and them play the game of 'see who is luckier', if it was exposed, it would definitely set off public opinion, and it was likely that he would go to prison, but he still did it.

Because Kazuki Kimura knew that the revival of Reiki was bound to come. And there will be a long period of chaos in the early stage of Reiki revival, so he has nothing to fear.

However, after a long time, Kazuki Kimura soon became alert, and he found that his thoughts were very sick, and he began to fall into demons. To put it another way, his three views began to be wrong.

The anxiety of crossing over, the discomfort of being in a foreign land, all made him have a strong inexplicable emotion, which made him very irritable and tyrannical.

But Kazuki Kimura was a doctoral student at a spiritual institute after all, and he had seen too much in the early days of the seminary. After many people have strong strength, their mentality is unbalanced and begins to swell. After that, he gradually fell into the devil and became mad.

When he felt that he had this kind of change, Kazuki Kimura quickly woke up, and he began to consciously channel his psychological problems, so that his mind would always remain in a peaceful state.

He began to rectify the Fengjian Department, formulated a study plan for the Fengjian Department, and slowly guided the members of the Fengjian Department to the right track. In this process, he is also studying carefully, using himself to influence the Fengjian Department, and also imperceptibly influencing himself.

He also teaches bad lessons, and he also advocates the use of violence to simplify complex things. But no more tyranny, no more sending others to the hospital for a trivial matter.

After realizing his psychological problems from Kazuki Kimura, it took him half a year to adjust and complete a psychological transformation.

The scene that Nagayama China saw in the heart of the tree lake was actually one of the results of Kimura and Shu's psychological transformation. And the biggest result is the change in the atmosphere of Sakurakuchi School.

At the same time that Kimura and Kiki changed themselves, they also changed Sakuraku.
