Shen Zhe, a graduate student in the Department of History, traveled through time to become the son-in-law of Dayan, and unexpectedly discovered that his father-in-law's family were all time travellers. Faced with his family's radical modern plans and the threat of imperial power, he pretended to be dormant and relied on historical knowledge to unite with the neglected King Yan to help him overthrow the suspicious and cruel Emperor Xuanwu. In the end, each of the Su family got their own place, while Shen Zhe lost his edge and lived a leisurely life as his son-in-law.
