Lin Mo is the most inconspicuous existence in the city. He is still working at the bottom three years after graduating from college. He is timid and often makes mistakes. He is ostracized by his colleagues and ignored by his boss. Even his roommates often ridicule him. After working overtime late at night, he accidentally picked up an old jade pendant covered with lines on his way home. From then on, his ordinary life was completely broken.
He began to encounter unexplainable strange things frequently: a vague figure wandering in the home of an elderly man living alone, strange footsteps in an office building late at night, and faint cries in an abandoned hospital. At first, he just wanted to escape, but he found that these supernatural events were always closely related to the people around him. If he did not intervene, someone would encounter an accident at least, or it might lead to tragedy.
Lin Mo, who has no special abilities, can only rely on his courage and a little bit of luck to find ways to deal with fear. He gradually discovered that those shortcomings that were regarded as "waste" - carefulness, patience, and even occasional stubbornness, turned out to be the key to finding clues and protecting others in supernatural events. Behind the old jade pendant, there seemed to be a bigger secret hidden.
