I Suppress Monsters and Kill Evil Spirits, but You Call Me a Devil?

In order to hunt down the four evil gods, Tang Hao came to the mortal world as a demon god, and was then besieged by the demon-suppressing Taoist priests. The murderous demon broke out, and when he was about to massacre Maoshan, he was informed by the system that there was a "four zero four" law, and he could not kill righteous people indiscriminately! But fortunately, the monsters in the mortal world are dancing around and evil spirits are everywhere, which can give vent to his overwhelming murderous nature: Since then, the world has had a murderous great devil who "kills evil with demons and combats violence with violence": "Why do you call me Big Devil?" "There are evil people who rape and humiliate a common girl! I will break her tendons and break her bones! Should I do that?" "There is a lich that is eating people's hearts! I'll behead him and whip his body! What's wrong with that?" "There is an evil spirit who refines corpses and controls ghosts! I crush their bones and scatter their ashes! Can I understand my hatred?" "I am dedicated to killing evil and defending the common people. I can be called the light of righteousness in the world!" "I am nothing but cruel and decisive in killing! But you want to call me a big devil?"... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
