Parallel to modern Blue Star, one day a mysterious high-dimensional game system suddenly covers the world. The real world is completely digitized, and all human beings are forced to become players. Cities, streets, and wilderness are reduced to various copies. Zombies, alien beasts, and game monsters appear crazily, and the human order collapses.
Players rely on killing monsters, clearing dungeons, and completing system tasks to gain experience, equipment, skills, and talents. Death is a real fall, with no chance of resurrection. They can form guilds, seize resource points, and compete for opportunities in secret realms. The law of the jungle has become the only law, and players around the world have fallen into crazy involution and fighting.
