When programmer Lin Ke activated the virtual world "Oracle" he created, he accidentally traveled through and merged with the soul of Karen von Esther, the cannon fodder aristocratic boy in the game. He discovered that he had the developer privilege of "Eye of Insight" and could analyze everything from a code perspective. Facing the fate of being killed by her fiancée, the legendary "Monster Princess" Evelyn von Nord, Karen used her programmer's thinking and understanding of the underlying rules of the world to turn the life-and-death crisis into an opportunity to fix system bugs for the "problem girl", thus starting a legend that rewrites destiny and changes the world.
