Soon, the boss "Line Master" discovered Qin Xiao's true identity and sent "Jingmo" to hunt him down. So Qin Xiao followed Song Yuan back to the police station. But he was caught in a loop, and it kept looping when two people were killed. Only by finding the real killer can the loop be stopped. Finally, Song Yuan found the killer, but the bullet had already flown out. Qin Xiao blocked the bullet to protect Song Yuan, but the loop ended...
