Soul-Eater

Yan Yichu is a shapeshifter from a blessed cave-heaven, commonly known as a "qi." After countless hardships, all he wants is to take human form, pass himself off as one, and blend into human society.

But humans are awful.

He barely got to enjoy himself before a self-proclaimed feng shui master tricked him into getting involved in all sorts of haunted cases.

After years as a ghost hunter, Lin Yuexun has encountered all kinds of inhuman creatures: pitiful ones, vicious ones, and foul-mouthed ones. But he'd never met anyone like Yan Yichu...

"...Don't pull down my pants."

"Lin Yuexun, you promised to help me imitate humans."

"That doesn't mean you need to pull down my pants, does it?"

"How am I supposed to know what humans look like under their clothes if I don't look? As the saying goes, a gentleman bares his balls, while a petty man hides his little thing. What are you hiding?"

"..." What had this ball of qi learned from humans?
