Qin Feng, a cultivator who lived for more than 1,200 years, was grateful for his fifty years of following Murong Yun. Before his death, he promised to marry his granddaughter Murong Wan and protect the Murong family for three years. This engagement was originally a deal where each got what he wanted - Murong Wan needed to stop the blind date arranged by the family, while Qin Feng had to fulfill his promise to his old friend. On the day she received the certificate, Murong Wan bumped into Qin Feng teasing a beautiful woman in the Civil Affairs Bureau, and the two had a tit-for-tat confrontation. Murong Wan bluntly said that she didn't understand why her grandfather let her marry Qin Feng, who had "achieved nothing", but she didn't know that this seemingly idle man in front of her actually had power all over Daxia.
