Introduction: SynopsisThe story takes place in northwest China in the 1990s. On the night when the Yellow River stopped flowing, a dark ancient coffin with iron chains wrapped around it appeared at the bottom of the river. The corpse fisherman Lin accidentally triggered the spell in the coffin, and a strange birthmark appeared on his right arm, giving him the ability to see the memories of the dead. At the same time, a mysterious signal suddenly appeared in the depths of Lop Nur. Su, a member of the scientific expedition team, took the "Piercing Fish Jade Fragments" left by his father and went deep into the desert, and found that there was a living "young version of professor Peng" in the mirror ancient city.The two met because of the resonance of the ancient coffin and the jade pendant, revealing a conspiracy spanning six hundred years: In order to resurrect Emperor Chongzhen, the Ming Dynasty Imperial Astronomical Observatory cast a "yin and yang double coffin" with a living sacrifice of 10,000 people, which sank into the Yellow River and Lop Nur respectively, forming a "gate of the world of ruins" that reversed life and death. Zhao, the leader of a multinational cultural relics group, attempted to restart the double coffin, but it caused the collapse of time and space-the Yellow River flowed backwards, the mirror people were rampant, and the desert swallowed the city.In order to prevent the end of the world, Lin and the Soviet Union's Loulan survivor Alena and the centenarian Zhou who was infected with the zombie Gu traveled through seven time and space nodes, including the ancient altar of the Yellow River, the point where Peng Jiamu disappeared, and the ruins of the nuclear explosion, and gradually discovered that they were the "lock" and "key" of the Yin-Yang coffin. In the end, they must make a choice: to exchange the reality for the continuation of one person's eternal stay in the world, or to break the cycle of reincarnation and face the unknown cause and effect catastrophe...Key charactersLin (male protagonist): a corpse retriever in the Yellow River, taciturn and tough, with a birthmark on his right arm that can communicate with the memories of the dead, and his true identity is the descendant of the "living sacrifice" of the Yin coffin;Su (female protagonist): the daughter of a geologist, rational and courageous, the fragments of the Pisces jade pendant she carries can predict the mirror time and space, and her blood resonates with the Yang coffin;Zhou: the only survivor of the Yellow River ghost coffin incident in 1949, an immortal "living corpse", who knows the truth about Peng Jiamu's disappearance;Zhao (villain): the leader of the multinational group "Huimen", a descendant of the Ming Dynasty Qintianjian, who attempts to restore the monarchy with the power of the double coffin;Alaina: the last "sand witch" of Loulan, who can manipulate the sea of ??sand and guard the secrets of the Yang coffin, and her body gradually becomes glass as she uses secret techniques....
