At the end of the Qing Dynasty and the beginning of the Republic of China, the world was out of order. When the Nanyang evil jade awakens Cixi's zombie army, the scientific police detective uses ultraviolet light to fight against the evil. Traditional Taoist priests, Jianghu snitches, and modern commissioners were forced to join forces to stage a life-and-death game in Gantian Town, where dragon veins intersect. There is also the hidden betrayal of fellow disciples, the awakening of the Yin woman, and the opening of rifts in the underworld - this is the ultimate collision of Taoism and gunpowder, loyalty and betrayal, human nature and demonic nature in the fission of the times. Every seal shakes the boundaries between yin and yang, and every choice rewrites the rules of coexistence of humans, ghosts, immortals, and monsters.
