A modern corporate slave dies suddenly from staying up late, transmigrating overnight to become Lin Xiaoxing, the notoriously mocked legitimate good-for-nothing daughter of the Prime Minister's estate in the capital! Bound to a slacking system where slacking brings rewards and overworking brings punishment, she has no desire to vie for favor, fight in the palace, or compete in talents—her only life goals are to eat, drink, lie flat, and slack off completely! Unexpectedly, an imperial decree betrothes her to Su Qinghan, the cold, abstinent, and overwhelmingly powerful Prince Jing. While others desperately curry favor with the prince, she only wants to sleep and bask in the sun. Hoping merely to survive peacefully, she accidentally opens a cheat code through her Buddhist-style slacking, charming the iceberg prince, winning over the adorable little crown prince, putting the hypocritical lotus stepsister in her place, and even earning the high appreciation of the emperor!
