When many people talk about why Concubine Yi was given the title of Marquis, they say that the Qin Fa is no more than this, and a favored courtier who has no merit and no merit will also be crowned a marquis? Ignorance is not terrible, the terrible thing is that you regard your ignorance as knowledge to look at all events, Yan Yi is meritorious to the Qin State, but later for his narration of the face, which leads you to think that Yan Yi is useless, Yan Yi was originally used because of Zhao Ji's favor, but this is not enough to be knighted in the strict qin state.

First of all, we must understand a problem, Yan Yi is indeed a false eunuch, and she also entered the palace after being wrapped up by Lü Buwei, but this is only the first time. After successfully entering the harem for the first time, Yan Yi did not have to hide it. No one said what kind of problems Yan Yi had, and Yan Yi was not a person who lived in the deep palace with Zhao Ji all year round, and his influence and role in state politics should never be ignored. What everyone may not know is that at that time, Yan Yi also had a luxurious mansion in the capital of the Qin Kingdom, and the scale of the mansion was constantly expanding, and even in the end it was able to catch up with Lü Buwei's Chancellor's Mansion.
Why is it so crazy? In our cognition, it is mentioned that Yan Yi is an attempt to launch a coup d'état, kill Yingzheng, and then his two young children usurp the throne of the entire Great Qin Empire for the King of Qin, but this matter is the second half of history, as for the first half of the period, no one may know, let alone anyone is willing to say. After returning to Qin, yin yiren took another wife and gave birth to Chengjiao, the most recognized and orthodox heir to the throne. However, he did not become the future King of Qin. After Empress Xia's death, Cheng Jiao lost her patron. And it has also been rumored that he is the true bloodline of the King of Qin, coupled with his ambitions, which eventually triggered a rebellion to kill Yingzheng.
At this time, Yan Yi was the first to learn the news and informed YingZheng, Lü Buwei and Zhao Ji, and obtained the Tiger Charm of the capital at that time, leading an army to cooperate with Lü Buwei to quell this rebellion. At that time, Yan Yi made a contribution to calming down the civil unrest and settling the country. This was even second only to Lü Buwei's last attempt to pacify the Six Kingdoms, so coupled with Zhao Ji's favor and consideration of the security of the capital at that time, he was crowned king.
After this, Yan Yi could meet with Empress Zhao at will, and the connection between the two was even closer, which also contributed to Yan Yi's desire for power within the Qin Dynasty palace and gave birth to further ambitions. At that time, this was indeed a big scandal, and Empress Zhao was not clear, but the problem was that at that time, this kind of court scandal was really commonplace, and for the Qin State, this was indeed unseemly, but in the later period, compared to the Chu State and the Zhao State, this was nothing at all.
The laws of the Qin state are very strict, and even the queen and empress dowager cannot touch the Qin law or the loopholes in the law at will. Even if the former dynasty had the support of Lü Buwei, it would not have been possible. Because Lü Buwei was only in charge of state affairs, and did not care about the judicial system of the Qin state. In other words, the judicial system of the Qin State is relatively independent, it does not involve the power of the king or the minister, nor does it submit to these authorities, so if Yan Yi wants to be crowned a monarch, he must make an immortal contribution, and Yan Yi performed very well. It also left the other ministers speechless, in the legal system of the Qin State, to meet the conditions for the title of king, not some historical and legal whites believe that he can become a prince when he goes to bed.
