In the cultivation world of the cat clan, there are no humans, only countless cats across the Nine Domains. Born with zero life slots, Ouzi, a lowly servant, has always been trampled beneath everyone's feet. That is, until a spiritual-pattern screen emerges from the bones of a fellow cat, revealing that he can hear other people's lives and steal them one slot at a time. Nine lives, nine desperate trials. Cast out of his sect, sold into a fighting cat arena, and forced to watch the only old cat who ever took him in being bitten to death. He does not cultivate. He only collects debts. The second-ranked, the third-ranked, and the Celestial Surveillance Catcher all come for him, one after another. But when he finally reaches the summit of the Heavenly Ladder, he discovers that the power he possesses was originally cultivated by someone else living in his place.
