"When the gunshots from the patrol room in the French Concession penetrated the rain, Gu Chenzhou was staring at the bullet hole in his heart in shock. In the last life, he was a useless detective who could not even count the footprints at the murder scene, and was shot like a dog by the Special High School Division; in this life, he Sitting on my knees at the scene of the murder three months ago, I listened to the cute "Xiaogui" broadcast in my mind - 'Detected: The deceased had opium cream on his sleeves when he struggled three hours ago, and the angle of the bullet mark on the window sill points to the third window on the second floor opposite.'
The useless detective's police badge was cold in the rain, but Gu Chenzhou smiled.
This time, he wants the wolfdogs of No. 76, The eagles of the special high school, and even the fate of his previous life to see what it means to be a "trail" - using traces as eyes and rails as blades. In the bloody storm in Shanghai, he, Gu Shenzhou, wants to be the one who exposes all conspiracies to the light. "
