Lan Ran only believes in two things in his life: logic and rules.
He can deduce the only way out of a deadlock in three minutes, and he can also make his opponents willingly hand over their trump cards at the negotiation table. He thought he was awake enough, until the APP that could not be uninstalled dragged him into an infinite world composed of soul fragments - each instance was a piece of sin, a piece of memory, and a judgment that could not be escaped.
Cang Jin doesn't believe in rules, but only in power.
He is used to opening the way with his fists and speaking with his blade. But in this world, he would always meet the same person - calm, restrained, and every word he said seemed like he was settling accounts. He should hate that kind of person, but he couldn't control his gaze.
They met again and again in the dungeon, forced to stand side by side, forced to trust, forced to see their own shadows in each other's eyes. They work together in a tacit understanding, redeem each other, and fit together like two lost pieces of a puzzle.
But they don't know why fate has tied them together.
——Some answers are hidden in the last copy. And the road leading there is on the tip of a knife every step of the way.
Concept: In a caged world where rules are paramount, human nature is infinitely magnified. The protagonist does not rely on brute force, does not follow the crowd, uses his IQ to break the situation, and uses his calmness to survive. He sticks to his heart in life and death games, tears apart the lies of the system, and finds his own way to survive.
