Medical genius Chen Yan accidentally traveled through the Zhenguan period of the Tang Dynasty and became the son of the founding hero. The original owner had a distinguished life experience - his two uncles died in battle for Li Shimin, and his father even died protecting the eldest queen, Queen Sun, during the Xuanwumen Incident. In memory of his loyal family, Li Shimin directly granted him the title of county earl after he ascended the throne. Chen Yan originally planned to lie down and enjoy himself, visit the flower houses in Chang'an, and become a wealthy and idle fish. Unexpectedly, he was stunned by a marriage edict. The emperor actually wanted to marry Princess Gaoyang to him! ! Chen Yan, who did not want to become a cuckold king for eternity, immediately decided to enter the palace and break off the engagement.
