Deep in the Qinling Mountains, a broken ancient bronze lantern caused waves for thousands of years; underground in Chang'an, an old secret scroll of the Deng Guan Department revealed the strange truth. Chen Mo, a down-and-out archaeological apprentice, stepped into the Qinling Mountains due to a mysterious commission and accidentally found the fragment of the "Ghost Cave Xuan Lantern". Since then, he has been involved in a shocking secret that spans from the Shang and Zhou Dynasties to the Tang and Song Dynasties.
Following the guidance of the bronze fragments, Chen Mo formed an expedition team with the slick Fatty Wang and the mysterious woman Lin Yao, from the Qinling Dragon Cave to the Chang'an Lantern Tower, from the Gusu Water Tomb to the Mobei Dragon City, and then to the Kunlun Snowy Abyss, the Ghost Cave in Western Hunan, and the Nanhai Shark Tomb... ... They deciphered the ingenious and treacherous Feng Shui formations in the dangerous secret realm of ancient tombs, encountered strange beings such as bloodthirsty leeches, lamp shadow ghosts, and the Luohua Cave Girl. They also struggled with various forces such as the mysterious organization "Xuanmen" and the Vatican Vault.
The emergence of each mysterious lantern fragment is accompanied by a buried historical secret: the sacrifices of the Shang and Zhou dynasties to communicate yin and yang, the shocking layout of the Tang Dynasty Guanlan Division to suppress the "earth demons", the legend of the blood curse in the Xiongnu Dragon Court, the mystery of the corpse lantern in the West Queen Mother Palace... Chen Mo gradually discovered that the mysterious lantern is not an ordinary weapon, but the key to sealing the ancient demons, and the process of collecting the fragments is gradually awakening the terrifying existence that has been sleeping for thousands of years.
When the seven fragments finally unite in the South China Sea Mermaid Tomb, Chen Mo not only has to face the crisis of annihilation when the inner demon awakens, but also uncovers the abyss of human nature behind the disappearance of his mentor and the betrayal of his uncle. In the intertwining of Feng Shui metaphysics and mechanical skills, in the collision of historical secrets and modern exploration, can Chen Mo and others decipher the prophecy of "the return of the seven sons and the opening of the ghost cave" with the heart of a lampkeeper?
