In history, who was honored as "the emperor's father" by Qin Shihuang? Without him, it is difficult for Qin Shihuang to unify the six countries.
Qin Shihuang was able to unify the six countries, which was inseparable from Shang Yang's political reform. Shang Yang's political reform laid a strong economic and military foundation for Qin, and in just a few years, he overtook other countries and embarked on the road of strengthening the country and enriching the people. But it is impossible to accomplish the great cause of reunification without the kind of generals who can command thousands of troops. As it happens, Wang Jian is a talent of Qin State.
There are two obstacles on the road to the reunification of Qin, one is Li Mu of Zhao and the other is Xiang Yan of Chu, which are the two most difficult bones to chew. But these two problems were solved by Wang Jian one by one.
Li Mu of Zhao is Zhao's backing. As long as Li Mu is still alive, Zhao Can will not be breached. This is not an exaggeration. At that time, Qin Shihuang also suffered a lot for this, but he could not beat Zhao. The road to crushing is definitely dead, so we can only try our best to get rid of General Li Mu. So Wang Jian bribed the villain of Zhao and used the suspicion of Zhao Wang to get rid of Li Mu. As a result, Zhao won easily.
Then Xiang Yan of Chu. At that time, a young general of Qin said that Chu could be captured with 200,000 troops, and Qin Shihuang agreed. Although the record was ok at first, the protracted war was too much for him and he soon lost. The man wore a tie and led the beaten army to flee back to Qin. At this time, Wang Jian stepped forward and asked Qin Shihuang for 600,000 troops, winning Chu in one fell swoop, and Xiang Yan was also killed in the war.
In this way, there will be no obstacles for Qin Shihuang to unify the six countries. Qin Shihuang led the army to destroy other countries and soon established the Qin Dynasty.
