On a rainy night, a wooden box lands on the inn's table. Inside is just one sentence: “Please kill me.”
Bai Jiu is the coldest “debt collector” in the martial world. He never asks where a debt came from or changes his price; he simply settles every score, one by one. But he soon discovers that the debts he is settling are not grudges, but part of an invisible web. Someone is using favors as bargaining chips and writing life and death into a ledger. Every job is tied to an old case and a hidden thread. The deeper he gets, the closer he comes to the truth.
When he finally lays hands on that ledger, he understands: debts can be settled, but the human heart cannot.
