The Old Enemy of the Beast

"Remnant Beast·Old Enemy" This is a severely polluted world, which is always shrouded in "grey rain", so that no place is absolutely dry. Those who are seriously polluted will undergo changes in their bodies until they completely transform into beasts. In the back alley of the black market, sixteen-year-old Lin Sudi was unpacking cardboard boxes, waiting for the news of his parents' death. Three years ago, they disappeared after performing the "Grey Fox Mission" and all their files were cleared. She entered the archives of the Purification Bureau and dug out fragments from the waste paper: a blacked-out name, a record of illegal inhibitors, and the sentence "Follow the established plan, no need to report." The remnant beast evolves in the dark, and pollution spreads within the body. Some people want her to know the truth, while others want her to never turn that page. And her only clue was an old man who was about to lose his strength and a photo that she didn't dare to open. She killed many people, but... She never thought that she was one of them... ——Tragedy is not an accident, it is an enemy carefully designed by someone.
