Under the old locust tree at the entrance of the alley, the yellow paper figures at the Chen family's green cloth stall are unusual offerings - they are "substitute talismans" that bear karma for living people and ward off evil spirits. There are hair-thin talismans hidden in the joints to maintain the yin and yang contract.
Chen Sheng learned how to make paper figures from his grandfather since he was a child. On a rainy night when he was twelve years old, he witnessed his grandfather using a red wedding dress paper figure that looked exactly like Axiu to fight against the resentful spirit of Widow Li who had been drowned in the river for three years. Burning all the paper figures temporarily solved the crisis, but half a year later Axiu went crazy, giving him a first glimpse of the weight of cause and effect.
After his grandfather passed away, Chen Sheng inherited the stall, but found that the facial features of the paper figures gradually resembled his own, and strange events happened one after another: an old woman in a bamboo hat ordered the same model of paper figures, the sound of paper being pasted came from the closet, and a paper figure in a white shroud dripping with water suddenly appeared on the edge of the bed. Grandpa's notes reveal the curse of the Chen family - if the natal double is used by others, he will be haunted by evil spirits.
In order to break the curse, Chen Sheng formed an alliance with Su Wan, the successor of the Su family's witchcraft, and Ma Chen, the orthodox corpse exorcist of the Ma family, and embarked on a journey against the evil sect. They broke into the paper boat seduction case in Qingxi Ancient Town, solved the paper man funeral ritual in Shacheng, solved the mystery of the Yin Fei of the Water Evil in Wuzhen, and searched for the lost "Yin and Yang Paper" to strengthen the "Corpse Paper Evil" sealed by the founders of the three sects.
From the Paper Man Reincarnation Formation to the Corpse Snake Formation, Chen Sheng used blood as a guide and soul as a contract to escape death many times, gradually uncovering the origins of the three sects and the grievances between their ancestors. He knows that there is no good or evil in the paper-man technique. Only by adhering to the original intention of "preventing disasters for others" can he fight against the evil spirits that devour the soul.
The green cloth stall under the locust tree is his eternal destination, and Chen Sheng's destiny is to protect the balance between yin and yang on the treacherous path where humans and ghosts intertwine with the entrustment of his natal paper man and his grandfather.
