Chen Xuan, a papermaker in a small town on the border of the Chu Dynasty, accidentally activated the golden finger that "lightens all things" while making paper figurines for the deceased, and all the paper figurines suddenly became spiritually enlightened. At first, it was just a small phenomenon of paper boys serving tea and paper horses pulling carts, but on the seventh day, it triggered the phenomenon of "Yin soldiers crossing the road" - a hundred thousand paper-tied Yin soldiers stepped through the underworld and wandered around in the world. From then on, Chen Xuan became the core of the "Fourth Natural Disaster", pursued by the Yins, encircled by Xuanmen, and coveted by demons and ghosts. Every time he stabbed a paper man, the disaster increased by one level. The cool thing was that the paper man jumped from lively to the ghost commander Mingjun. There was also the setting of the undead army that "the paper man can be reshaped after death in battle, and his intelligence only increases." In the end, Chen Xuan revealed that he was transformed from the "Guiding Paper of Underworld", and used disaster as a sword to redefine the order of yin and yang.
