Echoes from the Underground: 749 in Action

I am Lin Shen, affiliated to the Anomaly Observation Center code-named 749. We don't catch ghosts, we don't touch metaphysics, we only deal with the most evil and terrifying unsolved cases among the people: Circulating human voices underground in a deserted village, blood-colored floating figures in the corridors, cries in the middle of the night in abandoned school buildings, strange phenomena in the restricted area of an isolated island... People in the world are afraid of ghosts and gods, but we only believe in science. All horrors are physical phenomena; All weird things have reasonable answers. Go deep into forbidden areas, face your fears, and uncover the truth. 749 Has never been made public and has always been in action. There are no supernatural beings in this world, only unsolved science.
