[The main focus is the system + the cool points of counter-killing + the main focus is suspense + witty character design]
I died together with the mysterious organization, and I was reborn into the police force ten years ago!
Facing the massacre that shocked the entire city, everyone was helpless, but I activated the [God-level Detective Sign-in System] at the scene of the crime!
Bite! Sign in at the center and congratulate the host on acquiring the god-level skill: on-site retracement!
My colleagues laugh at me as a rookie, and criminals think that I am an idiot. Little do they know, I have already used the system to see through everything!
The identity of the serial butcher?
The truth behind the rich man's secret room?
As long as I sign in, the murderer will be naked in front of me!
I will make up for the regrets of my previous life with my own hands!
I will pay back the enemies from my previous life a hundredfold!
In this life, I will use the entire city as a chessboard to completely destroy the organization that attempts to "purify" the world!
