Ling Su accepted a mysterious commission to restore the memory of a girl (Yeye Tong) known as the "Blank Body". During the restoration process, he accidentally came into contact with a shocking secret covered up by the Giant Tree Group - the "Ouroboros Project." This plan aims to use a special "spiritual virus" to format some of the emotional memories of the entire city's residents, thereby creating a "perfect society" with absolute obedience and no negative emotions. As a result, Ling Su and Ye Tong were frantically hunted by the Jushu Group. They are forced to flee, and encounter "Echoers" along the way. Ling Su not only has to protect Ye Tong, but also finds clues to fight against the Giant Tree Group in the memory fragments she gradually recovers, which are difficult to distinguish between true and false, and finally faces his dusty past and the true role he played in the "Ouroboros Project".
