(Detective + Detective + Police Dog) Langchuan, a depressed patient who failed the postgraduate entrance examination, witnessed a strange murder in the building opposite when he was on the verge of collapse!
When everyone thought it was his delusion, only the blood stain on the air conditioner was smiling ferociously in the middle of the night.
The blurred vision behind the old glasses turned out to be the only sharp edge to pierce the darkness——
Is it the self-destruction of drowning in the abyss, or the pursuit of the murderer in a desperate counterattack?
"I can't even save myself, so why should I save others?"
"Because the moment the alarm button is pressed, you are no longer the puppet trapped in the pile of test papers."
When the police lights cut through the night, he saw the reborn light in his eyes.
This is a story about redemption, as well as a two-way hunt with inner demons and the real murderer!
