What About the End of the Ming Dynasty as Promised? Which One Are You Talking About?

What about the end of the Ming Dynasty as promised? I, a graduate student in the Department of History, traveled through time. At the end of the Ming Dynasty, the Jin army in the north is suppressing the territory, and internal uprisings are about to begin - I understand the standard apocalyptic script. Run south and survive first. Etc. What? No need to run? What? The city gate tower... Stood up? And beat the Jin army away? I rubbed my eyes. The city wall more than thirty feet high, the stars flying in the sky, the Yunqi army with a large sword on their waist - is this the Ming Dynasty? "This is Ming Dynasty." The young man who saved me said matter-of-factly. "But how can a spaceship take off and land on this city wall?" "That's Xingcha, you don't even know that?" "Then the Jin Army in the north..." "Oh, Bu Liren, cannibals are very vicious. But the Yunqi Army will take care of them." Bu Liren? Xingcha? Cloud Cavalry Army? I slowly typed a question mark. Etc. Zhu Ming... Also Ming? What about the end of the Ming Dynasty as promised?
