According to historical records, it is not difficult to find that Qin Qiong fell ill after a long battle and did not make new contributions later. According to statistics, Qin Qiong has experienced more than 200 battles and suffered many injuries. When I was young, I came out when I was old. Every time he got sick, he said, "I have been a soldier all my life, and I have suffered many serious injuries. I have lost a lot of blood back and forth. How can I not get sick? " Since the ninth year of Wude and the Xuanwu Gate incident, Qin Qiong gradually faded out of the political arena.
Cheng is definitely weaker than in combat capability. He lives a long and healthy life. The 24 heroes of Lingyange, except the old fairy Xu Maogong, are probably him. Cheng is straightforward and rude in romance novels, but in fact he is a very smart and smooth person.
He was deeply trusted by Li Shimin, Emperor Taizong, and was promoted many times. After the establishment of the Tang Dynasty, Cheng was not a hereditary lord protector. In the year before his death, he was renamed Lord protector, and his descendants were hereditary. Since then, Cheng has been in charge of the military affairs of Youzhou, Yi, Tan, Ping, Yan and Guangxi, and almost ruled over more than half of China's military forces, which shows that the people of the world trust him.
In any case, the two Founding Fathers were treated well by Li Shimin, and their endings were satisfactory.
