At the beginning of the story, Shen Wanning, a modern superpower who has experienced rebirth in the apocalypse, originally wanted to enjoy life in a peaceful world, but was mistakenly bound by a "two barrels" system and traveled to the Shen Mansion in the 38th year of the ancient Yong'an. The system explains that this is a small world established for the rebirth and revenge of the female protagonist, and the object possessed by Shen Wanning happens to be the sister of the original heroine Shen Wanrou.
