Humanity around the world has been forced into a national game called "Fantasy World" without any exit channel. The game is deeply bound to reality - death in the game corresponds to the complete failure of human body functions in reality and the declaration of death, with no room for recovery.
"Fantasy World" does not have any system-related settings, no panels, no attribute values, no task prompts, and no level divisions. All abilities, skills, and equipment require players to explore, accumulate in actual combat, and obtain adventures by themselves: skills rely on comprehension, imitation, and adventure inheritance, and equipment relies on picking up, forging, and trading with NPCs. Strength improvement depends entirely on actual combat experience, poison proficiency, and mental polishing. There is no "upgrade" routine.
