In order to take care of his comrade's sister, the King of Mercenaries, who made the world's enemies terrified of him, returned to China.

What? This little girl was actually the obedient little sister that good brothers talk about? Did he have to become so fast!

This won't do. My body is sick, I have to look for a doctor, and my heart is sick. I have to look for a teacher!

Wang Feng became the head teacher of the class of the delinquents.

What? This class is still a demon class?

And so, a massive war between teachers and students broke out...

Come, come, this female classmate, don't you like to play with Undead Pesticides? Teacher will bring you to the throne!

There's a little hoodlum bullying you? Don't move, let the teacher do it. If he doesn't beat them up, then we'll clean them up!

Hey, someone kidnapped you? Relax, in terms of rescuing hostages, teachers are experts!

As long as you listen to your teacher obediently and be a good young man in a beautiful society, you can do anything you want, hehe!

Good teacher but demon student
