The year is 2077, the 31st year of the Wasteland Era.
Gu Yuan is a memory cleaner at the Pure Memory Institute of the Third Sanctuary, specializing in erasing pain, fear and the past that should not exist for people.
Until an abnormal cleaning accident, he saw pictures in the client's memory that should not belong to him: burning streets, dead people, the mysterious double snake emblem, and a truth that had been buried for thirty-one years.
As the investigation deepened, Gu Yuan discovered that the so-called history of "purifying the world" might have been a carefully woven scam from the beginning.
The Forgotten Zone, the Society of Two Snakes, the Night Watch, tampered memories, the eradicated old people...
And he himself is not an ordinary memory technician at all.
When the truth awakens from the depths of his mind, Gu Yuan must make a choice between "the arranged safe life" and the "bloody reality."
In this wasteland of rust, radiation and lies, he wants to recover not only memories, but also stolen history.
