Everything in the world has a price, and even gods cannot escape paying their debts. The protagonist, Xavier, is the last Blade Creditor in the world. Carrying a coffin on his back, he walks alone, holding The Ledger of All Things, to collect a 300-year-old 'world-saving debt' from The Nine Immortal Venerables. He uses rules to judge false gods, uses contracts to defy fate, and embarks on a heaven-defying journey of 'violent debt collection' in a collapsing cultivation world.
