Gu Yang, an ancient book restorer, has a birthmark on his left wrist that allows him to glimpse the obsession of the deceased. A book called "The Book of Mountains and Seas" involved him in the mysterious case of the Liulichang fire 20 years ago. When a loved one was seriously injured by him, the "spiritual fire" inherited from his bloodline finally ignited in his palm. At the same time, the rich man Zhao Yuanzheng set up an evil altar, trying to penetrate the ancient well that imprisoned ancient terror. Facing the shadows that have accumulated for hundreds of years, as the last spiritual master in the world, Gu Yang must use this weak flame to burn away all the shadows and protect the world.
