(A morally ambiguous protagonist + decisive and ruthless action + satisfying power fantasy)
Ouyang Tian was once the captain of a clan's guard squad. He was imprisoned to save his beloved, only for her to be assassinated afterward. Hunted by the clan and facing life or death, he obtained a divine cauldron, became an Asura, and shook the heavens.
Better to be a tiger in the mountains than a lamb waiting for slaughter. Thus began his path to slaying gods.
I've become the Asura King, and you want to recruit me as a squad captain?
I've become the Celestial Emperor, and now you say you regret it?
Heh heh heh, the Lin family patriarch? Slay him!
The sect's ancestor? Get inside my cauldron, and we can talk!
Demon Ancestor? You say you want to come into my cauldron for a chat?
What? The Immortal Emperor? One sword strike, and he's done.
