At the end of the Qin Dynasty, the 500000 troops stood still because the first emperor of Qin had given a death order

In the spring and Autumn period and the Warring States period, the state of Qin gradually became powerful from Shang Yang's political reform, and gradually rose up to the East. At that time, when all the countries heard about the army of Qin, they were terrified, and there were a large number of people. Some people don't understand why the Qin Dynasty had such a powerful army. Did it take more than ten years for the army to collapse? Why was it defeated by Liu The peasant uprising army led by bang and Xiang Yu, even Zhang Han, who held the main army of Qin Dynasty, resisted Xiang Yu's attack by a miscellaneous army composed of disabled soldiers, wandering braves and slaves on death row. Where did the invincible Qin army go?

According to unofficial records, the regular Qin army had more than 500000 people. They were sent to South Vietnam by Qin Shihuang to pacify the barbarians. Qin Shihuang also ordered that no matter what happened in the Central Plains, they were not allowed to go north.

At that time, the Central Plains achieved great unification, but all parts of South Vietnam had not been pacified. If Qin Shihuang did not recover Baiyue as soon as possible, South Vietnam would bring hidden danger to the dynasty. However, Nanyue is located in the far south of the five ridges, with a vast territory and few people. To rule Nanyue is undoubtedly to develop a new continent, it is necessary to establish administrative organs. Therefore, Qin Shihuang sent Ren Xiao and Zhao Tuo as generals to lead a half million elite Qin army to attack Nanyue, and established administrative organs such as Minzhong, Nanhai, Guilin and Xiangjun there.

In addition, the Qin Dynasty also encouraged the soldiers to intermarry with the local people, take root in the ground, and gave death orders. No matter what happened in the Central Plains, the 500000 army was not allowed to go north. Why are they not allowed to go north? There may be two reasons. One is to let these troops, as the main force in the development of Lingnan, take root in South Vietnam, stabilize the border areas, and not be transferred casually. The other is to prevent some people from scheming to use this army to go north to seize power and usurp power.

To the great surprise of the first emperor of Qin Dynasty, after only 15 years of Qin Dynasty, the Central Plains fell into a chaotic situation in which Liu Bang and Xiang Yu competed for supremacy in the world. The 500000 army led by Zhao Tuo always adhered to the death order of "no matter what happens, they will not go north". They always stood still and watched the changes of the current situation in the Central Plains. When he learned that Liu Bang finally won the world, Zhao Tuo felt that the Qin Dynasty was gone, so he established the Nanyue kingdom with Wuling as the boundary. Since then, the 500000 Qin army has integrated into the Lingnan population and become the ancestor of all ethnic groups in Lingnan. It was not until Emperor Wu of the Han Dynasty that Nanyue was regained by the Han Dynasty, and Nanyue was officially destroyed.

At the beginning, the first emperor of Qin thought that the Qin Empire had been established and the world was even. The throne should be passed on to all generations, and there should be no war. So he gave a death order to send this 50 elite Qin army to Lingnan. Who knows, only to the Qin II, the world was in chaos, and all the heroes were fighting for the Central Plains. However, the death order of the first emperor of Qin became his curse to stop the army from going north, and also made the Qin Dynasty lose its last chance of vitality. If this 500000 Qin army was ordered to go north to save Qin, it is unknown whether Liu Bang would be able to sit in the world.
