Corpse fisherman Gu Linzhou was fishing in the Forbidden River at night when he fished out a future corpse with his name and "time of death in three days" written on it. Since then, the city's water flow has reversed, and weird rules have come one after another: if someone calls your full name in the water, you must agree; when the stage starts, you are not allowed to leave. A river god subsidy system that only rewards "saving people and breaking situations" comes to the door, and every subsidy must be pledged with moral character and fate. The Ming Bureau wants to seal the situation, and the Tide Club wants to let go - Gu Linzhou is caught at both ends, and he can only use the rules as a knife to go from being a corpse fisherman to being the leader of the tide.
