Fu Sinian, a top student in the Department of Modern History, accidentally traveled through time and became a down-and-out scholar during the Zhenguan period of the Tang Dynasty. It happened that Princess Li Lizhi of Changle fled to avoid marriage. In order to protect the royal face, Emperor Li Shimin appointed him, who had a relationship with the princess, as the "substitute consort". On his wedding night, facing the cold princess and the contempt of the civil and military officials of the Manchu Dynasty, Fu Sinian relied on his insights beyond his time to first improve the Quyuanli to solve the grain shortage in China, and then use a new gunpowder formula to help Li Jing pacify the Turks. In just a few months, he transformed from the laughingstock of the court to the pillar that Taizong relied on.
While he had to resolve the suspicions of Changsun Wuji and other old officials, he had to deal with the schemes of the concubines in the harem, and he also had to tame the arrogant Princess Changle. From taking charge of the Shence Army to presiding over the reform of the imperial examination, from opening up the Maritime Silk Road to promoting the innovation of printing, Fu Sinian worked step by step in the turbulent political arena of the Tang Dynasty. When Wu Meiniang first entered the palace, and when the competition between Li Chengqian and Li Tai for the throne intensified, the time-travelling prince-consort held the princess with his left hand and determined the world with his right hand, eventually pushing the Iron-Blooded Tang Dynasty to a more glorious peak.
