Lin Mo, a down-and-out history lecturer, accidentally came into contact with a top-secret file on the "Topological City". This legendary ancient city can distort space and cognition at will, and its shadow is quietly spreading to every corner of modern cities. When people around him begin to "evaporate" strangely, and when memory becomes unreliable, he discovers that he is not the pursuer, but the puzzle itself. Is it to uncover the ultimate secret of the ancient city, or to become a new component of it? The stakes in this game are reality itself.
