Traveling Through the Ming Dynasty, I, Zhao Kuangyin, Am Familiar with the History of the Ming Dynasty!

In the seventeenth year of Chongzhen, Zhao Kuangyin traveled through the Ming Dynasty and became the late Ming emperor Zhu Youjian. What's even more amazing is that before he came, he took a trip to the 21st century. The cold wind is biting and the arrows are like locusts. At the beginning, the army broke into the siege, but Wu Sangui stayed in Yutian and did not arrive. Good news: He has Zhao Kuangyin's military instincts and imperial mentality. Bad news: The Ming Dynasty did not raise horses, they had not yet mastered firearms, and the civil servants were better than his prime minister Zhao Pu. Outside the customs, Tatars and Mongols were eyeing the Ming Dynasty, and he knew better than anyone what these people would do in the end. What's even more troublesome is that the imperial city has been destroyed, and the palace roads of the Forbidden City are full of refugees and stragglers. And he only has two hundred eunuchs. "I have conquered the world all my life, and now I have to teach you unworthy descendants how to defend it?" Zhao Kuangyin (Zhu Youjian version) tore up the sinner's edict and drew his sword. From then on, the painting style of Chongzhen Dynasty changed drastically. Faced with Yan Guan's death remonstrance: drag him out and let him go to the Ministry of War class to learn "Firearm Application". Faced with the arrogance of the military commander: summoned into the palace, personally demonstrated the Taizu Changquan, and talked about the cost-effectiveness of "releasing military power over a glass of wine". Facing powerful enemies outside the customs: I opened my notes on studying Tatars and sneered: "Jianzhou Jurchens? I was in that place in the Northeast and had dealings with their ancestors." Not only did he want to save the Ming Dynasty, but he also wanted to see if the "law of historical cycles" that shattered the Song Dynasty's dream could still be played in the hands of someone like him who started the game himself.
