In the Yunmeng Realm, where the second dimension blends with the oriental fairyland, a saint of the Qingxiao sect disappeared mysteriously on the night of sacrifice. The star pattern on the cracked mirror at the scene was actually the same as the jade pendant lost by the "Fairyland Female Detective" Su Lingxi when she was a child. Su Lingxi was invited to investigate the case, and as soon as he locked on the clues about the dimensional rift, he met Shen Xingci, a funny boy who called himself a "tourist" - he mistakenly chewed the evidence grass and spawned bloody memory fragments. The two-dimensional moves he used casually could also suppress the energy of the rift.
The two teamed up to investigate, and from the grocery store of the hypocritical monk Liu Changfeng, they found that next to the "Shadow Eclipse Society" code name in his account book, there was the same black totem printed in the Saint Girl case; when they broke into the Phantom City, the imprisoned two-dimensional girl who was dying only left the words "The next target is...".
The death condition of the victim in the Hua Xian Valley murder case is consistent with the painting, and the handwriting of Su Lingxi's mother is hidden in the painting; the mutated roots of the Lingzhi Garden detect the energy of the Gu family's bloodline; the totem that appears when Shen Xingci loses control in front of the Tianxuan Secret Realm is actually the same pattern as the token of the leader of the Shadow Eclipse Society. Su Lingxi uncovered the past of accidentally falling into the crack as a child, and was shocked to realize that her mother's disappearance was exactly the same as the case of the Holy Girl; when Shen Xingci confessed his identity, a fragment matching the crack mirror was revealed on his waist.
When the darkened Avengers, the paranoid pursuers, and the leader of the Shadow Eclipse Society approached each other step by step, the two of them realized that all the mysteries were related to the dimensional disaster that was covered up twenty years ago, and their encounter might have been a well-designed game.
