In Tianjin Wei in the 17th year of the Republic of China, the Haihe River was full of undercurrents and strange things. Chen Sanshui, the last corpse fisherman in Jinmen, relies on his ancestral "Secret Records of Corpse Fishing" and his market wisdom to make a living by setting up a stall while observing the taboo rules of Haihe River.
Bizarre floating corpses appeared one after another on the East Floating Bridge. The dead were clutching strange octopus-shaped wooden sculptures, and the corpses were fixed in the river as if they were "rooted". The government was helpless, and the Green Gang forced Chen Sanshui into the situation with coercion and inducement. During his investigation, he discovered that the vision of the corpse was closely related to the secret hidden by Father Morrison of the Western Church - this seemingly benevolent missionary was actually a Cthulhu pagan believer who tried to use the sea and river sacrifices to awaken the old rulers and subvert the seals of local folk customs.
Chen Sanshui solved the mystery with the secret skills of the corpse fishermen, and used the local folk customs of Tianjin Wei to fight against the indescribable terror of Cthulhu: the water mirror showed the shadow of the evil god, the water sealing spell drove away the pagan minions, the water siege counterattacked the Green Gang's plan, and finally at the river god ceremony, he used the "life substitution technique" to hide the truth and expose Morrison's crazy ambition under the cloak of "redemption".
The waves of the sea and river calmed down for the time being, but the whispers under the seal never dissipated. Chen Sanshui held the corpse fishing pole and stared at the river, knowing that this game between man and evil gods, local and foreign land, had just begun...
