I Slay Demons and Evil, Yet You Call Me a Fiend?

To hunt down the Four Great Evil Gods, Tang Hao descends into the mortal realm as a Demon God, only to be surrounded and attacked by demon-subduing Taoists.

His bloodthirsty demonic nature erupts. Just as he is about to slaughter everyone at Maoshan, the System informs him that the "404" law forbids him from wantonly killing righteous cultivators!

Fortunately, the mortal realm is overrun with demons and monsters, and crawling with evil spirits, giving his raging bloodlust an outlet:

From then on, the world gains a murderous demon lord who "slays evil with evil and fights violence with violence":

"Why do you call me a great demon lord?"

"A villain forced himself on a woman! I severed his tendons and shattered his bones! Was that wrong?"

"A witch-demon dug out human hearts to eat! I cut off its head and whipped its corpse! What's wrong with that?"

"An evil demon refined corpses and controlled ghosts! I crushed its bones and scattered its ashes! Isn't that satisfying?"

"I devote myself to destroying evil and defending all living things. I'm the very light of righteousness in this world!"

"All I did was use brutal methods and kill without hesitation! And yet you call me a great demon lord?"..
