Shen Qingwu runs a small paper-making shop in the old city, where he works with bamboo strips and colored paper every day. She forgot about her past, and only vaguely felt that the lines drawn by her fingers should not be just decoration. Until an old lady ordered a "family portrait" made of paper, and a cold memory suddenly penetrated her mind - she saw fire, heard whispers of betrayal, and a vague but heart-stopping figure. The old piece of paper she carried with her moved automatically without any wind, and strange spells emerged, whispering the whispers of the dead that only she could hear. The amnesiac papermaker suddenly realized that the skills in his hands could connect yin and yang, carry memories, and summon the souls of the dead to tell the truth. In the darkness, the "senior brother" Lu Huaijin, who was known as the leader in the supernatural circle, was smiling and sucking her deeper into the fog. Every step of retrieving memory is a game with evil spirits and a confrontation with betrayers. Shen Qingwu holds paper as a blade and memory as a thread, vowing to pierce through lies and make all dust-covered sins appear in the flames of the paper soul.
