I Slaughtered the Horror World by Creating Urban Legends

I originally wanted to write an infinite-flow horror battle royale, but after thinking it over, I decided it sounded a little boring and there wasn't much I could do with it, so I'm switching to a different premise. What we know so far: 1. It's still an infinite-flow story, with horror instances. 2. After clearing an instance, the protagonist earns escape points, which can be used to create urban legends. 3. What are urban legends? Strange and bizarre tales passed from person to person. (That's my personal understanding.) The blurb won't be changed for now. If you're interested in this kind of story, feel free to add it to your collection. Theme: Eliminate the supernatural and remain a firm materialist.
