What's even more frightening is that from the faded "Monster Suppression" poster in the corner of my wall, there is an old murmur: "Let me out... I know the truth about spiritual energy recovery..." Now, the association wants me to be an undercover agent, the Su family wants me to be a key, and the Shadow Society wants to silence me. And I just want to pick up trash quietly...
