The Qin Dynasty, which unified the whole country, is a very strong dynasty in history, but we know that freezing three feet is not a day's cold, and the prosperity of a dynasty will never be the credit of a monarch. Qin Shi Huang counted seven monarchs, each of whom laid a solid foundation for the foundation of the Qin State during his reign, so many historians now when commenting on the process of the Unification of the Qin State, they will not forget to talk about the merits of the ancestors of Qin Shi Huang, but one of them only reigned for three days, but posterity said that the unification of the Qin State was indispensable.

The emperor, who reigned for three days, was called King Xiaowen of Qin, and he was the grandfather of Qin Shi Huang. Why everyone says that he is a Ming Jun, is because it turns out that King Xiaowen of Qin's grandfather, King Qin Zhaoxiang, had many sons, and King Qin Xiaowen was not the eldest son, and the eldest son at that time was born to the King of Qin and the Princess of Chu, and the eldest son also had the support of many courtiers under King Zhaoxiang of Qin, and was also recognized by Empress Dowager Mi.
Therefore, no matter how to count King Xiaowen of Qin, there is no chance, but the eldest son of King Zhaoxiang of Qin was killed, so our protagonist King Xiaowen of Qin appeared as the first heir. However, this is not the most bloody thing, King Qin Zhaoxiang reigned for too long, he lived for a total of seventy years, his eldest son could not survive him, which is also one of the longest living monarchs in Chinese history, and finally after the death of King Qin Zhaoxiang, King Xiaowen of Qin ascended the throne.
However, King Xiaowen of Qin was not a living long man like his father, and King Xiaowen of Qin died three days after he ascended the throne. The most critical point came, when King Xiaowen of Qin was making the crown prince, because his eldest wife Lady Huayang could not give birth to children, Lady Huayang wanted to let the second son Yiren be the eldest son of King Xiaowen of Qin, originally King Xiaowen of Qin was unwilling, but under the persuasion of Lü Buwei and Lady Huayang, King Xiaowen of Qin still set up Yiren as the prince, and sent a lot of things to Yiren to express his sincerity.
Originally, Yiren was an unnoticed prince, and when he was young, he was sent to another country as a hostage. But now that King Xiaowen of Qin regarded him as if he were his own and loved him very much, the status of the aliens in the hearts of the princes was also different, and finally sent the inhumans back. Therefore, after the death of King Xiaowen of Qin three days after he ascended the throne, yiren naturally became the king of Qin, and the yiren was Qin Zhuangxiang, the father of Qin Shi Huang.
Therefore, there are too many uncertainties in this period of history, countless accidental events make the impossible possible, and the throne of the King of Qin itself cannot fall on the King of Qin Zhuangxiang, and there will be no Qin Shi Huang, so he is called ming jun, and the answer is really ironic. But it was by such a historical accident that King Xiang of Qin zhuang became the prince, and every king will have many sons, but it is his turn, it can be said that the pie really fell from the world.
It can be said that King Xiaowen of Qin's contribution is to seize the throne for King Xiang of Qinzhuang, because the overthrow of a country is very easy, if the throne is passed to the hands of others, and he encounters a dark king, it will definitely make the hundred years of achievements of the Qin kingdom fall short, so this is also an interesting story in history.
