Lin Ye, a high school student, fell asleep in a boring history class and in his dream broke into an ancient tomb of the Western Han Dynasty filled with earthy smell. The sound of dripping water in the dim corridor, the strange murals on the walls, the bones scattered beside the coffin, and the terrifying figure lying on all fours and making a "ho ho" sound, everything is so real that it is suffocating.
When he woke up from the nightmare, he found that reality was strangely overlapping with the dream - a group of ancient tombs of the Western Han Dynasty suddenly appeared in the back of the school, the history teacher died mysteriously and tragically, and traces similar to the monsters in the dream appeared on the bodies of his classmates. What made him even more horrified was that a tomb robber named Chen Mo, who looked exactly like himself, suddenly appeared, claiming that he was the reincarnation of the tombkeeper of the Chen family, and that he was also the container chosen by the ancient beast "Taotie".
As the night of the full moon approaches, the seals in the ancient tombs gradually loosen, and puppets controlled by vicious beasts wander around the campus, and the shadow of death is approaching step by step. Lin Ye was forced to be involved in this fateful entanglement that spanned thousands of years. Holding a bronze bell and a yellowed diary, Lin Ye shuttled between reality and fantasy. He had to fight against the real monsters in the ancient tombs and face the secrets hidden in his own blood.
When the red light of the soul stone illuminated the tomb, and when the blood of the three clans was about to complete the final sacrifice, he realized: this dream that started in the classroom was never an illusion - it was an ancient contract repaid with life...
