Haru was the best mage in the Japanese army. Building up a amazing reputation before deciding to give up his life in the military and settle down.

 His plans were cut short as he found himself in the body of a baby.

 He taught himself magic again from scratch before finding himself in a dire situation whilst on his first school trip causing him to give up on magic and take on the art of Chinese cultivation. 

His master was a soul fragment of an ancient cultivator who placed his soul inside of a golden ring in the shape of a dragons body.

 What kind of mysteries did this ring hold?

 And who was this cultivator who saved Haru from the brink of death?

The Legendary F Rank

Screams of terror shot throughout the school while Haru laughed like a madman from within the Principal's office. The sounds had gained an audience at the receptionist's office, and they looked on with terror, imagining what kinds of atrocities were going on behind the closed door.

The receptionist had already called the police and was filling them in on a description of Haru while waiting for them to arrive. If he were strong enough to defeat the Principal in one move, they would have to send the elite magic task force to deal with the situation.

Many of the students pulled out their phones and recorded the door to hear the cries of pain, but not a single one of them dared to get close when suddenly the sounds were overlapped with blaring sirens outside the school.
