After Breaking Off the Engagement, I Became the Prince Consort of the Great Zhou Dynasty

In the tenth year of Yongle, Li Tianle, whose family was in decline, held on to his last glimmer of hope and went to Beijing to join his future father-in-law with a marriage certificate. Unexpectedly, the Minister of Etiquette turned his back and refused to admit his mistake. A marriage certificate was exchanged for a shabby manor. Just when he was about to lie down and become a happy landlord, the injured woman he rescued turned out to have a powerful background - the eldest princess of the dynasty. From then on, this time traveler who just wanted to eat and die was forced to make soap, make refined salt, write poetry, and reform the military system, and accidentally turned the Zhou Dynasty upside down. And his biggest worry is: in the future, his brother-in-law will be the emperor, and his future wife will be the eldest princess. As a prince-in-law, is he still considered a son-in-law?
