Lin Yan, a graduate student in the Department of Modern History, got drunk at the graduation banquet. When he woke up, he traveled to a parallel dynasty that did not exist in the history books, the Dasheng Dynasty, and became the famously stupid prince Zhao Yan of the Zhenguo Palace. His predecessor had just been beaten to death on the spot for being frivolous with Princess Zhaoyang. Before he could figure out the situation, he was kidnapped by his father, Zhao Chongshan, and taken to the palace for questioning.
Zhao Yan originally wanted to pretend to be stupid, fight cocks and walk dogs, and live in peace for the rest of his life, but fate never gave him a chance:
- Emperor Li Shisheng slapped the case: "You must be this consort even if you don't deserve it!"
- Prince Li Chengxuan pleaded: "My dear sister-in-law, without you, my uncle's throne will be unstable!"
- Princess Zhaoyang threatened with a mallet: "Qin... Zhao Hanzi, if you dare to leave me, I will fight you to the death!"
- The officials scolded angrily: "Zhao Hanzi, we will fight with you!"
- The alien clan wailed: "Zhao Hanzi is our clan's biggest enemy!"
He shouted "I don't want to do this anymore", but he didn't leave anything behind: rectifying the Qianniu Guard, checking the household deficit, reforming the salt policy, pacifying the northern Xinjiang, regaining the southwest, showing off the Haijiang, promoting reforms, and establishing Zhao Learning... From the stupid son-in-law who pretended to be crazy, to the prime minister who strategized, and then to the retired grand master, he used modern knowledge to stir up the chaos in the court, and also gained love, family affection and friendship in this strange land.
