Chen Mo, a researcher of Ming history in the 21st century, during a cultural relic restoration accident, his soul traveled back to the eighth year of Chongzhen in the late Ming Dynasty and possessed a 16-year-old scholar named Shen Yu. After waking up, Shen Yu quickly accepted the fact of time travel. Faced with the Ming Dynasty that was about to collapse in only nine years, he gave up his grand fantasy of changing history and set his goal to protect his family. He used his understanding of history to explain to his traditional-thinking father Shen Zhongan the inevitable trend of chaos in the world, and proposed a bold survival plan.
