During the 47th sedative injection in the mental hospital, Lin You's three personalities were competing in his consciousness: the paranoid person deduced data, the cold person calculated tactics, and the crazy person eager to break the rules. The bloody countdown on the wall reveals the truth - the hospital is the first copy, the barcode on the back of his neck is the system key, and he is the only surviving triple personality container in the military's "humanity experiment".
Female doctor Jiang Xiaoxiao reveals her identity as "Observer No. 07", And her necklace contains a childhood petri dish photo of Lin You as the 12th clone. In the dungeon, he used a prism to disintegrate the inner demon of the mirror image and face the extreme self-projection, only to discover that all BOSS are fragments of human nature that have not been accepted, and the Shadow Weaver organization is using this to recharge the catastrophe weapons.
When rationality and madness collide on the spiritual battlefield, three personalities emerge and collaborate: the paranoid breaks the situation, the ruthless executes, and the crazy subvert the rules. Jiang Xiaoxiao used supernatural powers to anchor his existence, and he had an epiphany at the moment he accepted the split - the answer to this experiment that began at birth is hidden in the contradictory symbiosis of human nature.
The triple blood lines on the newborn baby's eyes indicate that the game of "Inner Demon Hunter" will never end, and human nature itself is the most dangerous loophole in the rules.
