Zhenye woke up from the exhaustion of playing games all night and found that he had traveled to a parallel world called Blue Star and became an ordinary college student. This world is far crueler than he imagined - all countries around the world are forced into a game with strange rules. Each country randomly selects a chosen person to participate, and the whole process is broadcast live globally. The life and death of the chosen person is directly tied to the national destiny: failure will deduct the national destiny, and losing consecutive games will face the crisis of national annihilation. At this time, the Dragon Kingdom has suffered five consecutive defeats, and its national destiny is on the verge of drying up. If it loses again, the entire Dragon Kingdom will completely disappear from Blue Star. At this critical moment, Zhenye was randomly selected and became the new chosen one of the Dragon Kingdom. He was forcibly drawn into the 3S-level high-risk copy - "Dark Balala Demon Fairy". The rules of the dungeon are weird and unpredictable, hiding deadly contamination and unknown horrors. There are only two conditions for passing the level: survive for seven days, or clear the final contamination. The chosen ones from all over the world have their own thoughts, and the live broadcast barrages are intertwined with curses and prayers. The hope of the Dragon Kingdom is all pinned on this young man who accidentally traveled through time. Relying on his pre-travel game thinking and keen observation, Zhen Ye holds the only chance to be prompted. In the twisted and strange world of the Demonic Fairy, he works step by step to crack the rules and traps and fight against pollution and erosion. He vows to break the Dragon Kingdom's losing streak, protect the lives of millions of compatriots, and become the last light to save the Dragon Kingdom.
