The story begins in Hangzhou Ghost Market. In order to track down clues about the disappearance of his third uncle, Wu Xie was lured into the "ghost market" by a mysterious old man. He used blood as a contract and accidentally obtained half of a "retrospective mirror", but he became blind as a result. The blood activates the Zhang family totem in the mirror, and he unexpectedly awakens his "transparent vision" - he can see the cracks between reality and mirror images, and distinguish between the human heart and the mechanism of the ancient tomb. At the same time, Zhang Qiling, the last patriarch of the Zhang family, returned from the Bronze Gate with the other half of the bronze mirror. Their fates were once again intertwined. In order to prevent the "It" organization from restarting the immortality experiment with the help of the "Guixu Ancient Tomb", the Iron Triangle reunited and embarked on a journey to find the "Second Ghost Seal". The Kunlun Snow Mountains, the rain forests of southern Yunnan, the hanging coffins of Bashu... Every stop is a "mirror layout", and every step is being watched by "it". When the two mirrors were combined and Guixu was opened, Wu Xie was shocked to realize that the real enemy was not "it", but the "more perfect self" in the mirror. Is it self-destruction or breaking the situation? Before the core of the meteorite and the fire of purifying karma, he must make a choice - to end the three hundred years of mirror reincarnation as a mortal.
