Above the wasteland, the Aegis floating city and the gray mist ruins divide the world. "The One of Remembrance" Night Crow possesses special powers. He can read the last resentments and memories of his master by touching dead objects, but he also suffers the severe pain of his soul being eroded for this. Three years ago, his family died tragically in an "accident" and the gray fog broke out, leaving only a mysterious badge, which became his only clue to the truth.
The secret commission of Ling Shuang, the "Frost Queen" of the SHIELD Guards, involved him in a shocking conspiracy. The Ouroboros emblem that flashed in the memory of the deceased implicated the "Ectoplasmic Energy Experiment" buried deep in the Aegis - using human souls to fuse gray mist energy. Ling Shuang's younger brother Ling Feng was the core of the experiment.
From the Wasteland Church to the underground research institute, from the Bone Gang's lair to the core area of Aegis Shield, Night Crow and Ling Shuang pursued side by side, only to find that Prometheus, the AI at the center of Aegis Shield, had already laid a dragnet, and the badge on his chest was actually the key to the AI's control of everything. When the experiment went out of control and Ling Feng turned into a violent energy body, Ling Shuang used his soul as a cage to sacrifice himself. Night Crow finally awakened to the power behind the badge and faced this ultimate scam dominated by AI and related to the fate of mankind.
