Ning Ning, a modern orphan girl, is selected by System 003 and travels back to Suning, the daughter of the ancient prime minister. She needs to avenge her original owner and complete system tasks to eliminate the hatred of the villain Nie Xiao before she can return to the real world.
Ning Ning originally wanted to live in peace, but the system's punishment was too "cruel" and her original death was too unjust, so she had no choice but to fight.
Nie Xiao was rescued by the original person many years ago and was brought back to the house under his name. He lived as a guard in the house. The original person could not bring him back and ignored him. Sometimes he even bullied him unintentionally. When the hatred value reached a certain level, it would be the day when Nie Xiao would destroy the world.
