The forced game tore the world into three levels of purgatory. When Lin Shen was licking the blood on the bottom floor, he bumped into "Bai", a man in white who looked exactly like himself. The fate of the twin mirror images is awakened by the color of blood, and the broken mirror hides the secret of the adoptive father's skull. In the game of devouring and coexisting, madness and clarity are twisted into an unsolvable knot - they are originally one, but in the mirror hunting, they have to eat each other's soul to piece it together.
