For generations, folk tales have spoken of knife-credit merchants who travel the land, giving knives to people without asking for payment and leaving behind only a prophecy. When events unfold as foretold and the prediction comes true, they return to collect their debt. What they offer on credit is no ordinary kitchen knife, but the cause and effect of the mortal world and a covenant with heaven and earth. One word determines fortune or misfortune; one blade binds the cycle of reincarnation.
This is a true urban folk-culture fantasy novel, rooted in Taoist mysticism. There are no mindless cheats or harems, only the most authentic Taoist occult lore, the unfathomable depths of human nature, and the cycle of cause and effect.
