Their business was spread all over the world. There were also descendants of the Qian family serving as officials in the court, and many forces in the world had good relations with them. However, Mingyuan, the leader of the Qian family, suddenly became seriously ill, and the medicine was ineffective. In order to continue her vitality, she listened to the sorcerer's words and let Chen Shu, who was born in a poor family and had a troubled family, marry into the Qian Mansion for happiness.
