Although Qin was brave and fierce and relied on his own strength to recover the Six Kingdoms, but there was no successor, Yu II perished, and there were too many reasons for Qin's demise, but the most important reason was still related to the issue of heirs.
If Qin is really succeeded by Crown Prince Fusu, everything is not yet known, and Hu Hai can succeed to the throne, inseparable from the help of Zhao Gao, from this point of view, the demise of Great Qin is actually Zhao Gao's impetus, then in history, the real Zhao Gao has several skills?

The real Zhao Gao
In various records, Zhao Gao is described as an extremely vicious person: pit Li Si, pit Fu Su, pit the entire Great Qin State, and even many readers also describe him as an eunuch who does not learn any skills, but only flatters.
However, according to some archaeological discoveries in recent years, Zhao Guo, who was able to subvert the Qin state by himself, was not only not an eunuch, but even a learned man, and his ability to defeat Li Si was completely a collision of intelligence, and even his martial arts were unpredictable.
At the beginning, Qin Shi Huang was able to defeat the Six Kingdoms, relying on talent, Qin Shi Huang gathered outstanding people across the country, and the method of selection was examination, as long as the knowledge was strong enough to obtain the position, which was very similar to the imperial examination of the descendants, and Zhao Gao was the best of them.
According to records, Zhao Gao's first position in life was Ling Shi, when he served as Ling Shi, Zhao Gao was only twenty years old, and then passed many examinations, Zhao Gao not only rose step by step, but also won the appreciation of Qin Shi Huang and was promoted to The Order of the Zhongche Government.
This official position can explain three things, first of all, Zhao Gao's knowledge is very high, to know that Qin Shi Huang's side is full of talents like Li Si, can get the appreciation of Qin Shi Huang, which is enough to show that Zhao Gao's knowledge will not be much worse even if it is worse than Li Si.
Secondly, Zhao Gao was definitely not an eunuch, Qin Shi Huang himself hated eunuchs very much, in the Qin period, eunuchs did not have any rights in the palace, and Zhao Gao was able to hold such an important position, which is enough to show that he is not an eunuch.
The last point is also extremely important, the Zhongche Government ordered this position to look like it is only to manage Qin Shi Huang's carriage, but Qin Shi Huang's groom is not a simple groom, being able to control horses is only a basic operation, the key moment must be a warrior who can kill the enemy with a knife, and to reach this position, Zhao Gao's martial arts must not be simple.
Zhao Gao and Li Si
If Zhao Gao's specific ability cannot be seen from the official position, then judging from the bond between Zhao Gao and Li Si, perhaps Li Si is indeed inferior to Zhao Gao.
Compared with Li Si, Zhao Gao is an extremely rigorous and very methodical person, which can be seen from Zhao Gao's ability to write the "Love Calendar", and Zhao Gao's erudition can also be seen from his final position.
After Becoming Qin Shi Huang's confidant, Zhao Gao did not stop his own path of promotion, but sent him to the side of his younger son Hu Hai and made him one of Hu Hai's teachers. Although Hu Hai was not the first candidate for the throne in Qin Shi Huang's heart, Qin Shi Huang loved his young son very much and could be sent to Hu Hai's side, indicating that Zhao Gao's knowledge was highly recognized by Qin Shi Huang.
In fact, after coming to Hu Hai's side, Zhao Gao began to conspire against Hu Hai's succession, and on the last parade, Qin Shi Huang had died, although Li Si hid this matter, but as a confidant of Qin Shi Huang, Zhao Gao obviously knew the truth of the matter, so Zhao Gao began a series of plans.
First he lobbied Hu Hai to give him the idea of succeeding to the throne, and then he seduced Li Si and asked him to help rewrite the edict and help Hu Hai ascend to the throne, as a minister who accompanied Qin Shi Huang to take the Six Kingdoms, Li Si was actually seduced by Zhao Gao, what a scheming and scheming.
The most terrible thing is that after Hu Hai took the throne, Zhao Gao immediately persuaded Hu Hai to put Li Si in prison, and directly killed Li Si without retribution, the whole process was completed in one go, without dragging mud and water, on the means and political vision, Li Si was defeated in front of Zhao Gao.
Zhao Gao died in Qin
In this way, Zhao Gao completely became the most powerful assistant around Hu Hai, but the next move was even more elusive, zhao Gao, after killing Li Si, also killed the chancellor Feng Zhiyi and others one by one, leaving only Meng Yi, these ministers who held military power.
Did Zhao Gao want to be a traitor like Wei Zhongxian and hold the power of the dprk? Hu Hai, who had recently ascended to the throne, died unexpectedly soon after, and Zhao Gao also found the baby and prepared to kill the last bloodline of the Qin family.
Fortunately, Zi Bao got the secret report, and finally killed Zhao Gao, and this matter was able to end, but it was too late, the world was already in chaos, and there was no one around the newly ascended baby, and finally liu Bang was beaten into Guanzhong and became Liu Bang's prisoner.
Judging from Zhao Gao's various deeds, he may have only one idea, to completely destroy the Qin state and restore the world to a situation of fragmentation, and those who have this kind of idea must have an identity, that is, the remnants of the Six Kingdoms, and xiang Yu who had similar ideas at the beginning.
Xiang Yu had only one goal from the beginning of the army, that is, to destroy the Qin state, whether he could successfully become king after defeating the Qin state and smoothly unify the whole country was not his main consideration, plus Zhao Gao's surname, Zhao Gao was likely to be a certain proton of the Zhao state at that time, and the descendants left in the Qin state.
This kind of statement is not empty, in the Qin Dynasty, compulsory education was not popularized, and only the children of the nobility could learn knowledge. For example, Liu Bang, who founded the Han Dynasty, has not been able to change his rogue and illiterate nature, but Zhao Gao, a non-official eunuch family disciple, can have no less knowledge and high martial arts than Li Si, which is very suspicious in itself.
Secondly, why Zhao Gao must support Hu Hai to ascend to the throne, at that time, Fu Su's ascension to the throne was basically a matter of certainty, Zhao Gao with his own knowledge, after Fu Su ascended to the throne, it was also very easy, he supported Hu Hai to take the position, the achievements obtained were not necessarily higher than the Fu Su on the top.
According to Guo Moruo's archaeological findings, the real cause of death of Qin Shi Huang was a three-inch long iron nail behind his ear, and if he wanted to do it in this position, he must be very close behind Qin Shi Huang.
Zhao Gao was able to rely on his own strength to turn the qin dynasty agitators on horseback, and his comprehensive strength could be seen, he could write and fight, and his mind was meticulous, not luck at all, if he had already gained power in the early years of Qin Shi Huang, whether Qin Shi Huang could establish the Qin Dynasty or not was an end full of unknowns.
