In the perfect urban "Light City" where technology and neon are intertwined, every citizen lives in worry-free happiness. The history they are proud of is a heroic epic without stains and full of glory.
Lin Mo, a young man who inherited his grandmother's antique shop, unexpectedly discovered that he could sneak into other people's dreams. He originally thought it was just a kind act to heal the soul, but during deep dives, he came across the "blanks" that had been carefully erased in the city's memory - the forgotten souls under the landmark "Light Tower", the bloody truth behind the official heroes, and the "purified" disasters and plagues.
A mysterious organization that calls itself the "Guardian of Reality" tells him that the terrifying monsters that turn into "nightmares" in his dreams are viruses that corrode reality and must be eliminated. And he is the one "purifier" chosen from thousands of people.
However, when he got a "reincarnation mirror fragment" that reflected the truth, he was horrified to discover: the "nightmare" he was fighting was the guardian of the real history; the organization he served was the culprit of tampering with the world; and his own forgotten childhood was the beginning of all lies.
In this huge lie disguised with happiness, Lin Mo must make a choice: continue to be a tool to maintain false peace, or become a "false historical archaeologist" to salvage the truth, even if it awakens pain that the entire world cannot bear?
