Logician Lin Yan woke up in a strange pure white room with only corpses and three rules of death around him. With extraordinary synesthesia and logic, he led the survivors to escape, but found himself falling into a deeper nightmare.
The emotional furnace, the mirror corridor, the hall of decision - each level is a carefully designed death trap. After forming an alliance with detective Zhao Meng and doctor Su Wan, they gradually uncovered the cruel truth: this was actually a "screening experiment" conducted by an ancient system on countless worlds, and all struggles were just observed data.
When Lin Yan finally broke through the rules and faced the "Shadow of the Origin" that created everything, what awaited them was an existence even colder than the gods. The system begins to disintegrate, and the three of them stand on the ruins and must make the final choice - to be annihilated with the old world, or to fight for their own way of survival for all enslaved souls in the ruins of the rules.
