Medical genius Chen Yan accidentally traveled back to the Zhenguan period of the Tang Dynasty and became the son of a founding hero.

The original owner had a distinguished background——

His two uncles died on the battlefield fighting for Li Shimin, and his father died while protecting Empress Zhangsun in the Xuanwu Gate Incident.

In recognition of his family's loyalty and bravery, Li Shimin directly granted him the title of county earl after he ascended the throne.

Chen Yan had originally planned to lie back and enjoy himself, visiting all the brothels in Chang'an and living a life of luxury and leisure, but he was stunned by an imperial decree granting him marriage.

The Emperor actually wanted to marry Princess Gaoyang to him!

Chen Yan, who did not want to become the eternal cuckold, immediately decided to go to the palace to cancel the engagement.

Unexpectedly, Princess Gaoyang kicked open the door of the Bo Mansion with the arrogance of the royal family.

As soon as the two met, they were like water and fire. They disliked each other and started to quarrel passionately on the spot.

A farce of anti-marriage protests shocked Chang'an, but Li Shimin sneered and made the final decision: "I want to see which of these two hedgehogs can pull out the other's quills first!"
