Back Room: Why Did My Ghost Story Guide Fail?

​[Tag: Systemless + Hardcore Survival + Weird Rules + Wise Fighting + Back Room Space] "Old Lin, don't panic! This is the back room Level 0, which is a novice teaching level. As long as we stick to the wall and don't look back, we will never encounter a physical monster!" When his best friend, a senior fan of ghost stories, swore this sentence, Lin Yan saw a monster with the face of his best friend and bloody fingers, lying like a spider on the moldy yellow ceiling, grinning strangely at him... … ​Senior fan settings? Security level strategy? It's a life-threatening talisman! When the urban legend came true, Lin Yan desperately discovered that this infinite maze known as the "back room" was not a rigid program at all. It is peeking into their memories, evolving in real time based on the "levels clearance strategy" in their minds, and creating more deadly mutant rules and monsters! Here, the cell phone battery is a countdown to death, a familiar face is a life-threatening lock, and the so-called "security level" is a hotbed of mental breakdown. No system, no magic, no superpowers. A sharpened security door key, a leaking Zippo lighter, and half a pack of crushed cigarettes. This is the story of a mortal, in an infinite space where common sense collapses, using pure physical laws and extreme minds to fight against mental pollution. "Since your ghost story strategy is ineffective, use my laws of physics to redefine this abyss!"
