It tells the story of Lin Mo, a monk who failed to survive a catastrophe and was reborn as a mortal. He was accidentally involved in a conspiracy that spanned a thousand years. On the surface, he is an ordinary tenant of the teahouse in the old city, but in fact he is tasked with preventing the "Shadow Pavilion" from opening the forbidden place "Ruins". In the process of searching for the truth, he met Liu Ruyan, a Taoist descendant who inherited his master's legacy, and Lin Xiaowan, a girl with a pure Yang destiny who was guarding the ability to see spirits. He also discovered that the seemingly ordinary teahouse owners and mountain guards around him were inextricably linked to the conspiracy.
From the evil spirits in the abandoned mines, to the remnant stele of the Tongjie Formation at Qingxuan Temple, to the Yin Gathering Formation underground in the old city, Lin Mo gradually uncovered the secrets of the "Xu" - it was not a place outside the realm, but the shadow of the world that devoured everything. In order to gain power from the ruins, Shadow Pavilion did not hesitate to sacrifice living souls, and Lin Mo was the "chosen one" who was prophesied to be able to seal the ruins gate. He holds three tokens: the Suppressing Spirit Pendant, the Kun Position Token, and the Essence of Lihuo. In life-and-death battles, he deals with the bronze masked man of the Shadow Pavilion and other forces, and has to face the sacrifices and betrayals of those around him.
This is a game between a mortal body and an extraordinary evil spirit, and it is also a practice about protection and redemption. When the total lunar eclipse comes, the ruins gate in the core of the earth is about to open. Lin Mo must make a choice between sacrifice and perseverance, using his remaining spiritual power and immortal Taoist heart to block the world from being devoured by the shadows.
