In 4022, humanity entered the interstellar age. Xia Country had lost touch with its history, and its historical heritage was even less impressive than that of Sakura and Goryeo.
Su Yang was exiled through time and space to the Ming Dynasty. His soul and body were separated: his soul inhabited the eight-year-old imperial grandson Zhu Yuntong, while his body lay like a vegetable somewhere in Yingtian Prefecture, cared for by a farmer's daughter.
Looking at Zhu Yuntong, the transparent nobody in the Eastern Palace, who wept and had neither his father's affection nor his stepmother's love,
Su Yang pretended to be the old man living in a magic ring and sighed. "Don't cry, kid. Your cheat has arrived."
Su Yang transmigrated to the Ming Dynasty for two reasons: to clear his name and to search for Xia Country's lost history.
Goryeo: "The Ming Dynasty has been our vassal state since ancient times. Our general shot out one of Emperor Zhu Yuanzhang's eyes and captured him, bringing him to the capital. Zhu Yuanzhang knelt and begged for mercy, ceding half his territory."
Su Yang: "At last, I can report this to Old Zhu."
Old Zhu: "Shot in the eye, then knelt and begged for mercy? Are you talking about me?"

Talk nonsense for a long time, regardless of your own safety
