Mc can give his life for her even he's injured it's more like the girl(master) and Mc(servant) bond but wtf Mc's going berserk again and again

I think it's probably related to mc's past remember he hate the academy ? maybe his sister got killed by them or his gf

that guy's cultivation sure seems to be dangerous! :O

Damn, he's going through it huh, good thing he has some powerful company/allies with him right that's willing to help him.
