"Double Tray Tomb: The Horror of the Nine-Layered Coffin" opens the thousand-year conspiracy of Captain Mo Jin! In the northwest Gobi, a bloody pointer appears on a bronze compass, a mysterious note invites people to go to the Crescent Moon Spring, and the legend of a ghost cave opens the door to death. Zhang Jiuye and his apprentice Chen Mo stepped into the game, only to see the secret text of the witch clan looming on the sheepskin map. What the woman in black robe handed over was not only the sheepskin scroll, but also treacherous clues to the cause of the master's death.
Deep in the ghost cave, a nine-story coffin hangs upside down, a double-disk bronze altar resonates, and thousands of ghosts howl as the cocoon squirms. From the blood pattern maze in Mogao Grottoes to the bronze tombs in the Qinling Mountains, from the Ice Soul Gate on the top of Changbai Mountain to the Shark Tomb in Guixu, Nanhai, every step is stepped on the bones and blood of the Wu clan's millennium conspiracy. As the compass divides and closes, the truth about the three compasses' unification emerges - the so-called key is actually the shackles of the witch ancestor's rebirth; it seems to solve the mystery, but in fact it falls into a deeper cycle of blood sacrifice.
When blood streaks covered his heart, and when the bronze sword split through the ice mist, Zhang Jiuye was shocked to realize that he was the ultimate container! Lin Wan'er, surrounded by mysterious shadows, the witch saint under the mask, and the petrified cave keeper, each of them holds half of the truth. Deep in the ghost cave buried by wind and sand, when the ultimate formation is activated, will it break out of the cocoon and become a butterfly, or will it be doomed? The moment the bronze compass stopped rotating, the bronze bell under the Arctic ice started a new countdown...
