If You Forget, You Will Die.

When Lin Ze realized that he was disappearing from the world, the number suspended above his head had returned to zero. No one remembers him. The mother denies having a son, colleagues regard him as nothing, and his face is fading in the photo album. He passed through the cracks in reality and entered a city made of consciousness - the Quantum City, a prison for those forgotten by the world. Here, memory can be embodied as a weapon, and forgetting is the real death. There are three road signs in the center of the city, pointing to three "roads to liberation": the road of silence teaches you to accept loneliness, at the cost of giving up yourself; the road of integration allows you to never be alone, at the cost of melting into the collective; the road of observation allows you to see everything clearly, at the cost of no longer being able to be emotional about anything. Three roads lead to the same destination - you are no longer "you". Lin Ze found his father who had been missing for twelve years in the abandoned study anchor point. His father told him the secret on the back of the stone tablet: there is a fourth road, a road without signposts that requires two people to serve as anchors for each other and create together. But the Observer Tower has noticed this unusual father and son. The gray-robed "Chosen One" broke in, claiming to eliminate all possibilities that should not exist. In order to protect Lin Ze, his father burned his anchor; Bai Xiaoyu almost lost his name in the resonance tower; Chen Mo almost sat down in the Silent Zone and never got up again...
