Late Night Code: a Survival Guide for Police Academy Students

At 0 o'clock in the morning, the whole city is still sleeping. Lin Yue, a senior student at the police academy, has a death manual with his name in his hand. There is only one line on the first page - at 0 o'clock tonight, don't open the door. The doorbell rang. Standing outside the door was a face exactly like his. When the strange rules come true, deadly codes begin to dominate the city. From the strange knocking on the door of the old house to the replica of another self in the subway, death follows you everywhere. While others relied on brute force to survive, Lin Yue used the investigation, observation, and criminal investigation reasoning taught in the police academy to turn the death rules into strange trump cards for counter-killing. This is not a monster illustrated book, this is a survival guide for police academy students.
