Upright Ghost Tamer: "I'm a proper Ghost Tamer. I punish evil, promote good, hunt down evil spirits, and keep the ghost-hunting world at peace. Oh, and I have an official position, too."
Qi Tian: "I don't care. I don't make exceptions for the righteous. If it's a ghost, it has to go!"
Villainous Ghost Tamer: "I..."
Qi Tian: "Cut the crap! Take this first!"
Ghost: "..."
Qi Tian: "You don't deserve a place at the table!"
Qi Tian transmigrates to another world with a golden finger: every ghost he destroys greatly boosts his base physical strength.
Before long, bad news spreads through the Ghost Taming world. Rumor has it there's a lunatic outside who loves killing ghosts, a completely deranged man who goes around looking for spirits to hack apart.
And he's terrifying. One punch blows a zombie's head apart, while the slit-mouthed woman bites him and knocks her own teeth out.
Everyone in the Ghost Taming world can only hide their ghosts and keep them out of sight.
Qi Tian: "Playing hide-and-seek with me? Here I come~ If I find you, you're getting beaten to death~"
It's just rather boring and supports a single female protagonist.
Classic: Offending someone, being caught and feeling aggrieved, dozens of chapters, dozens of chapters on the water
