Lots of Mysteries

Why can't I see anything with my eyes open? Because, suspicious cases are full of mystery! Solve the mystery of the double secret room, chase the murderer for seven days and seven nights, and set off a storm of anti-terrorism... Clear away the filth in the world and restore justice to people's hearts. Justice, truth and conscience are what the brave should uphold! The gray line of grass and snakes lies thousands of miles away! If you like this style, please follow the protagonist, Chen Yan. He was an airborne scout, a community worker, a police officer.
