Reading warnings: 1. The full text is in the first person, extremely dark, the protagonist's three views ≠ the author's three views; 2. The system is not a cheat, but a "living" one; 3. Each chapter is more than 2,000 words, no irrigation, no slap in the face, just horror; 4. If you feel any discomfort, please exit immediately. ———————— Volume 1: It's in My Head ————————
