The story revolves around Chen Xiu, a former detective and now a watchmaker. Three years ago, Chen Xiu retired due to the tragic death of his partner Lao Qiang. He hid in a watch shop in Siming Lane under a pseudonym, trying to stay away from the bloody past. However, a blood-stained clock sent late at night dragged him into the abyss again. This clock is not only related to the mysterious death of banker Zhou Shian, but also conceals a murder mechanism, pointing to a death ritual called the "Thirty-Third Night Banquet". In this chapter, a skilled killer attacks a watch shop at night. Chen Xiu relies on his calmness and dexterity to kill his opponent, but before he dies, he learns the strange name of "Thirty-Three Night Banquet" and his old identity "Lin Yin". What's even more disturbing is that the blood-stained clock suddenly starts running on its own at midnight, as if the countdown to death has restarted. Chen Xiu must race against time to uncover the bloody conspiracy behind the gears before the next "Night Banquet" begins.
