After Qin Mugong succeeded to the throne, he appointed Baijila, Jianshu, as counselors, defeated the State of Jin, captured Jin alive, and destroyed Liang, Rui, Slippery and other countries. Qin Mugong once helped Jin Wengong to return to the State of Jin and seize the throne, which realized the goodness of Qin and Jin. Qin Mugong turned around and developed westward. He tricked Yu Yu, who had defected from the State of Jin to the Rong people, into being a counselor.
According to Yu Yu's plan, Qin gradually eliminated 12 countries established by Xirong people. Zhou Wang congratulated Qin Mugong on defeating the Rong people and gave him a golden drum, hoping that he would continue to attack the Rong people vigorously. When King Xiang of Zhou, Qin Mugong sent troops to attack the country west of Hanguguan, and expanded its territory for more than 1,000 miles. Therefore, King Xiang of Zhou appointed him as the uncle of the western governors, and then he dominated Xirong, laying the foundation for the unification of China by Qin in the future.
During Qin Mugong's reign, he recruited wise men and boldly appointed foreign talents, which was the first of Qin. Inspired by him, Prissy, horse expert Bole and Jiufanggao, known as the "Five Doctors", voted for him one after another. Because he always adopts the method of "taking the essence and forgetting the coarseness and forgetting the outside" in employing people, he has achieved great success. According to historical records, during his administration, he "benefited the country for 12 years and opened Wan Li", and the whole vast western region was under his control.
Qin Mugong is also a man who is good at managing the army. Qin people have a tradition of raising horses since ancient times, which can be said to be a nation on horseback. After Qin Mugong came to power, he took advantage of this to set up a cavalry unit and equipped every soldier with a dagger. This is much earlier than the restructuring of Zhao Wuling's riding and shooting. The idiom "hand-to-hand combat" also comes from this. Qin Mugong died in 62 1 year BC and was buried in Yongcheng (now southeast of Fengxiang, Baoji, Shaanxi).
