Besides the influence of Queen Sun on him, it was the eunuchs around him. At that time, the border minority Wala attacked the Ming Dynasty on a large scale. Zhu Qizhen, a youthful man, was encouraged by eunuch Wang Zhen, listened to Wang Zhen's slanderers and led 500,000 elite troops of Daming. This army was accumulated by his father and even grandparents. In the end, under the rumor of trusting Wang Zhen, 500,000 troops were wiped out. This is the famous Battle of Civil Fort in history. It is no exaggeration to say that Zhu Qizhen is both wonderful and stupid. The brilliant performance is that he actually listened to the slanderous remarks of a eunuch, regardless of the safety of hundreds of thousands of troops, which eventually led to such a result. So the failure of this campaign was largely caused by human factors.
On the other hand, after being captured by Vala, the emperor's face was greatly insulted, which also made him deeply reflect on his previous mistakes. Later, through personal efforts and compromise, Zhu Qizhen returned to the Ming Dynasty, which was not the Ming Dynasty at that time, but the Ming Dynasty ruled by his younger brother Zhu Qiyu.
After returning to China, he began to plan the restoration work. The biggest obstacle to Zhu Qizhen should be Zhu Qiyu, but the one that has the greatest influence on him is Yu Qian. Yu Qian's outstanding ability was reused by Queen Sun, and later he was the secretary of records, which saved the Ming Dynasty in times of crisis and won the hearts of the people. However, Zhu Qizhen must die. For such a meritorious minister, he actually wants to kill him. There may be complicated reasons for this, but it is really wonderful to do so.
