In the future city "Xin Feileng Cui" where memories can be extracted, stored and traded, Lin Chen, a top memory retrieval expert, has a blank past that cannot be touched. He is like a lonely island, guarding the memories of others but lost in his own sea of forgetfulness. One day, a mysterious woman named Su Ying brought a taboo commission: to retrieve a memory that had been forcibly erased from an "empty shell" (a person with complete amnesia). This dangerous journey not only dragged Lin Chen into the dark vortex of the "Yongyi Group" at the core of the city's power, but also forced him to face the truth that he had forgotten and was closely connected with a disaster called "White Flame".
