After a lavish party, Su Wanqing mysteriously falls to her death. With the Qin family's interference, the police hastily close the case as a “suicide caused by depression.” While sorting through her belongings, Lin Mo discovers an encrypted USB drive left behind by Su Wanqing. It contains scattered clues from her investigation into the “Ouroboros” society, along with an incomplete list of names.
Devastated by grief, Lin Mo realizes that the law cannot deliver justice. He chooses the most resolute path. Using the resources and connections left by his father, who could be written as a retired special forces soldier or intelligence agent who withdrew from service due to injury and then disappeared into ordinary life, and drawing on his own exceptional intelligence, he begins an intensive training regimen in fitness, hand-to-hand combat, tracking, and hacking. From this moment on, his life is devoted to revenge.
