Qin Yaoguang, a relentless and highly successful modern-day corporate executive, dies suddenly from overwork and transmigrates into the world of a historical web novel. She wakes up in the body of the wicked Eldest Princess, a woman infamous for ruthlessly abusing the five children sent back by her husband, the Prince Consort, who has been away at war for ten years. In the original story, these five abused children grow up to become incredibly powerful and vicious villains who eventually exact a gruesome revenge on the Princess by severing her limbs.

Arriving just as the original owner is torturing the third child, Yaoguang quickly assesses the situation and decides to change her deadly fate. Treating the chaotic princess's estate like a new corporate acquisition, she leverages her modern business acumen to root out corrupt servants, neutralize scheming relatives like the original novel's manipulative female lead, Zhou Qinghe, and gradually attempt to win over the deeply traumatized and hostile children through genuine care and strategic problem-solving.
