Two years after a notorious cybercrime case was closed, the city has learned how to recognise its warning signs. Then a new body appears. The scene contains details that were never released to the public. Evidence from the original investigation resurfaces. A familiar pattern returns in a form that is bloodier, more deliberate and impossible to dismiss as coincidence. But this time, the victims were never part of an online game. Someone is murdering them personally. As investigators search for a revived network, forensic evidence begins pointing towards the one person who should understand the crimes better than anyone else. Blood appears where it should not exist. altered footage creates impossible timelines, and confidential records are transformed into weapons. Yet digital analysis reveals a disturbing contradiction. The suspected target has received no messages. No instructions. No contact at all. The killer is not inviting anyone to play. He is constructing a case, one body at a time. And when the final scene is complete, the police will not only find another victim. They will believe they have found the murderer.

The victims have nothing in common except the violence of their final moments. A student enters a restricted building and never returns. A family home burns while someone remains deliberately inside. Another teenager commits an act so horrifying that even the surviving witnesses cannot explain it. Police classify the incidents as isolated tragedies. Schools respond with counselling programmes. Officials warn about academic pressure, online influence and concealed emotional distress. Families are left to grieve while official reports suggest that the victims made their own choices. Then the evidence begins repeating itself. An unusual substance appears in separate toxicology reports. Symbols emerge at unrelated locations. Damaged phones produce the same brief sound before their data disappears. At the same time, an eighteen-year-old student begins changing. He stops eating. He barely sleeps. He vanishes during school hours and returns with injuries he refuses to explain. His anger becomes increasingly unpredictable, yet no one can identify what is controlling him. When one missed moment causes everything to collapse, police finally discover a possible connection between the living and the dead. But finding the pattern is only the beginning. Somewhere behind an ordinary screen, someone is waiting for the next person to obey.

Five masks have become the face of Jiangzhou's terror. They rob banks in broad daylight, bomb public places, ambush police convoys and kill without mercy. With every attack, the city grows quieter, the death toll rises, and the criminals disappear without leaving a single clue behind. Captain Lu Zhenkai and the Jiangzhou Metropolitan Police Department are ordered to end the nightmare. But his exhausted team is already struggling with grief, internal conflict and relentless media scrutiny. When four elite special officers arrive to reinforce them, pride and blame threaten to divide the very people who must fight together. Behind the violence is Pei Zhaolin, a brilliant gang leader whose hatred of the police began with an injustice against his father. He does not simply want revenge. He wants to break the department, terrify the city and force every officer into a game where arriving seconds too late can cost another life. Jiangzhou is running out of time. And this time, the police are not hunting the gang. The gang is hunting them.
