My Reality Has Been Replaced

Our reality is a thin piece of paper floating above an abyss. Beneath it, the dimension called the "underworld" continues to erode, replicating everything into a terrifying "copy of reality." Archivist Gu Xu, a man who firmly believes in order, is forced to become a "passer" and enter the twisted space to survive. The power he relies on to survive all comes from the abyss, and every time he uses it, he must pay a "price" of memory, emotion, and even humanity, making him gradually become the monster he fights against. What he will face is not only the horror that devours the world, but also the former heroes who advocate cold sacrifice. When the truth is questionable, what is the cost of guarding an illusion?
