Librarian Shen Yuan accidentally touches a mysterious spell and travels back to 1908 - a zombie Republic where dragon energy has declined and evil spirits are rampant! As soon as he arrived at the Yizhuang morgue, he was treated as an "uninvited guest" by the young Taoist priest Lin Jiu (the future "Uncle Nine"). In order to survive, Shen Yuan was forced to become a disciple and learn the Taoist "Thousand Character Classic" from scratch.
However, the peaceful apprentice life was broken by the strange "dead transformation". A mysterious jade talisman in Shen Yuan's body manifests strange phenomena, and it can actually arouse evil spirits! After the master and apprentice investigated, they found that the man behind the scenes was Smith, a foreigner who collected "exotic stones" and catalyzed the transformation of corpses. Traveling to foreign trade at night, fighting against Nanyang's head-hunting masters, and nearly being buried in the mouth of a dragon... Shen Yuan gradually realized on the edge of life and death: what he was carrying was actually the fragment of the ancient Yu King's split jade, which was used to suppress the nine "Xiangliu poisons"!
When the fragments resonate, the world will fall! In order to prevent the ancient evil god from resurrecting, Shen Yuan and Uncle Jiu embark on a thrilling journey: the Kunlun sword sect searches for the fragment, and outwits the Jiuju sect Onmyoji Chiyo; the Mongolian grassland secures the war spirit and faces Genghis Khan's violent spirit; explores the Qin Emperor's Mausoleum in the Qinling Mountains, breaks the mercury killing array, and competes for the core Jade Gui... When the fifth fragment merges into his forehead, Shen Yuan becomes the true successor of Yu Gui, and the ancient catastrophe has just begun! Can he gather all the nine pieces of jade and regain control of Kyushu in a chaotic world full of zombies?
