Yu Kun, the gangster, first joined the underworld eighteen years ago and offended his opponent, so he was forced to give away his newborn daughter. Eighteen years later, he became the largest gangster in the world. He went through great hardships to find his daughter Yu Xiaotong, who grew up in an orphanage. At this time, Yu Xiaotong was adopted by the Jiang family, a wealthy businessman, and became an adopted daughter. However, as the Jiang family's biological daughter Jiang Xi was found, Yu Xiaotong was targeted by Jiang Xi, a scheming woman. Because Yu Xiaotong had a weak personality and often had troubles, her adoptive parents also favored their biological daughter.
