In the world of "Tomb Robbers Notes", the iron triangle of Wu Xie, Zhang Qiling, and Fatty Wang accidentally triggered an ancient mechanism related to the secret of "immortality" during a follow-up exploration of the Qixing Lu Palace. At the same time, due to the cruel competition in Alice's game, the puppet Zhen Hong in "Rose Girl" was forced into a time and space rift by the enemy puppet, and fell into the tomb where Wu Xie and others were. On the verge of death, Zhenhong used the Virgin of the Rose as a medium to sign a contract with Wu Xie, who has a "pure heart", and uses human life energy to maintain his existence. The connection of the contract not only gave Zhen Hong the ability to act in another dimension, but also allowed Wu Xie's blood to incorporate the doll's "Rose Power", which can not only sense the "emotions" of traps, but also temporarily awaken Zhen Hong's fighting form in crises.
As the Iron Triangle goes deep into the Xisha Undersea Tomb, Qinling Sacred Tree, Yunding Heavenly Palace and other places, Zhenhong gradually discovers that the mystery of "immortality" in the world of "Tomb Robbers" is actually inextricably linked to Rose Girl's "Alice Game" - the Queen Mother of the West's "Corpse Pill" and the "ultimate" behind the bronze door may contain the answer to the fate of the doll. In the process of getting along with Zhenhong, Wu Xie gradually became each other's only "contractor" from being wary of "inhuman existences" at first. When the secret of Zhangjia's ancient building is revealed, Zhenhong is faced with the choice of "returning to the Rose Girl world to continue the game" or "staying with Wu Xie to fight against fate." The contract between the two will determine the survival of the two worlds.
