Shen Ji, the former ace criminal profiler, closed himself off due to excessive prying into people's hearts, and has long been indifferent to life and death. An accident caused him to board the non-existent "No. 404 Underworld Train".
Here, death is the only rule and fear is the currency. While everyone was trembling under the monster's claws, Shen Shen was calmly calculating the probability of escape. Until he woke up the man who was chained and exuding an aura more dangerous than a monster in the sealed forbidden carriage - Qin Lie.
Qin Lie is the only "violator" on the train and the nightmare of all dungeon bosses. He pinched Shen Shen's neck and smiled wildly: "Little profiler, guess what, do I want to kill you, or do I want to sleep with you?"
Shen Jing pushed up her blood-stained glasses and said expressionlessly: "Based on the degree of contraction of your pupils, you want me to help you unlock this lock."
This is a game between madman and genius, as well as a desperate rush about redemption and destruction. From testing each other to fighting back-to-back, they join forces to kill gods in infinite dungeons and tear apart this hypocritical reincarnation.
Purpose: Reshape human nature in a desperate situation stripped of morality
