As a Spy, I Can See Hidden Hints

[Aura recovery + copy flow + unlimited flow] The eternal night is coming suddenly, and strange things are rampant in the world. In the old hospital, faint cries can be heard; in the office building in the early morning, dense bloody fingerprints cover the walls; at the window of the abandoned community, vague figures appear and disappear under the dim light... People were horrified to discover that the world they were once familiar with had become extremely dangerous and strange, and it had become a forbidden place for the living, filled with terrible curses. Until, a dark and dilapidated investigation bureau appeared out of thin air... A group of cursed people are forced to join the Bureau of Investigation and step into these strange places to investigate the sources behind these events... A young man wearing a black trench coat, a huge black scythe, and a pair of scarlet eyes that see everything, gradually grew into the most taboo being among this group of people... People... Called him... Inspector Death.
