A wildly popular virtual reality game, Oracle, suddenly merges with the real world after five years in operation. Monsters, dungeons, skills, and levels become the new laws of Earth. The former top players are reduced to the bottom of society, while our protagonist, an "ancient legend" who left the game five years ago for personal reasons, will use his unique understanding of the game, long since forgotten by everyone, to rise to the top and become king in this new world.
