This is a work that combines "infinite flow" and "female suspense", but its core is neither killing monsters and upgrading nor reasoning to solve crimes. Its core is two words: alienation - people are alienated into tools by work, alienated into symbols by life, and alienated into dust by the times. The heroine Lin Man is in a strange building. Every "monster" she encounters is essentially an alienated ordinary person. And her mission is not to kill them, but to understand them - or even save them.
