Time, No, That's Not What I Care About Most!

When global time inexplicably stops, a phenomenon called "cognitive pollution" divides the world. Each contaminated area is constructed from a person's deepest consciousness and memory, becoming a cage that distorts reality. Lin Shen, the librarian, suffers from time perception disorder and is trapped in the library made up of his own cognition. The hourglass in his hand does not measure time, but the "certainty of his existence" - when the sand runs out, it is the day of self-annihilation. He must find his "untainted core": not time, memory, or emotion, but the very essence of what makes him who he is. However, the cruel rule is: only one person can escape each time of purification. In this battlefield where the cognition of self and others erodes each other, and it is difficult to distinguish the authenticity of memory and fiction, Lin Shen gradually realizes that this disaster is actually a cold test of the limits of human consciousness by an unknown entity. The blue sand in the hourglass keeps flowing. When everything he cherishes may be falsified, he must answer: If time and even self can be polluted, what is it that you really care about most? And on the edge of the collapse of all cognition, a truth more shocking than escape is waiting to be revealed.
