Rong Yu had just won the National Physics Prize when he was hit and killed by a car while trying to save his eight-year-old son. As soon as he opened his eyes, he was transported to seventy years in the future, where an eight-year-old cute boy instantly transformed into a bad old lady from a famous family, with a group of careless great-grandchildren as a gift. The boss is a love-minded CEO, Pei Haoshu, who is smitten by his secretary's girlfriend. He doesn't care about his own daughter but takes advantage of him to be the father of someone else's daughter. Lao Wu is known as a bad student and a bully in school. Before Rong Yu could accept the fact, he was blocked in the corner by Lao Wu, "I heard you are interested in me?" But was slapped away by the old man. "You evil beast! Kneel down! This is your great-grandmother Lan Rouxue!"
