History professor Ye Fan accidentally traveled through time when he cursed Chongzhen in class and became the young emperor's teacher. It happened to be the night when Zhu Youjian ascended the throne, and he dreamed that he would hang himself on Meishan seventeen years later! A professor who is a troll with knowledge about future generations, and a desperate emperor who is afraid of hanging. The two hit it off. Killing eunuchs, seizing corrupt officials, building guns, and imposing sea bans... Ye Fan led Chongzhen all the way and turned the Ming Dynasty into an empire where the sun never sets with granaries everywhere and thousands of nations coming to visit. Seeing that his seventeen-year death date was approaching, Ye Fan ran away, leaving only a note: "Your Majesty, I cut down the tree where you were hanged. Next, let's go conquer the stars and the sea?"
