Qin smashed the hotel.

After Qin's reunification, all the weapons in the world were destroyed, and I hope there will be no war in the world. By this time, the Qin Empire should have adjusted its national armament. In addition to the Guanzhong stronghold and the garrison of the world fortress, many Qin people who had to fight in the battlefield all the year round were faced with laying down their weapons and being farmers with peace of mind. Since then, their wives and children have been hot.

But in the last years of Qin Shihuang, there was another great war, with 300,000 troops chasing Xiongnu in the north and 500,000 troops conquering wuyue in the south.

Wuyue's 500,000 troops, especially criminals, mothers-in-law, businessmen and other people at the bottom of society, were recruited temporarily according to the old system. After years of no war, the scope of conscription and participation in the war at this time is certainly not limited to Qin people, including men from six countries after the reunification of Qin State.

Understandably, these people had no sense of identity with the Qin empire, their pace was inconsistent, their fighting capacity was not strong, and they were very depressed from the beginning.

The army finally captured wuyue and took root there. This army didn't come back during the Central Plains chaos.

Liu bang entered the customs because the defenders in Xianyang were empty.

At the end of Qin dynasty, there were many insurgents. According to historical records, Zhang Han led Lishan criminals to form an army, and at one time he made great strides, destroying Chen Sheng and Guangwu and defeating Xiang Liang.

The main body of this army should be Su Wei in Xianyang, like the northern and southern armies in the Han Dynasty. It is precisely because Xianyang E-Guard was sent to the front line that Liu Bangcai easily entered Guanzhong without great resistance.

The Qin Empire also had an elite division-the Great Wall Army. After Meng Tian's death, the lieutenant, Wang Jian's grandson, left and took over the power of commanding the army.

At that time, in the Battle of Julu, Wang Li was the main attack, and the troops led by Zhang Han were only responsible for transporting food and grass. It can be seen that the Qin dynasty sent back the northern border guards to support the suppression of the insurgents.

Unfortunately, in the Battle of Julu, Xiang Yu and Ying Bu joined forces, Ying Bu ran out of food to contain Zhang Han, Xiang Yu bashed head-on, and finally defeated Qin Jun, and Wang Li was captured.

Xiang Yu is facing 400 thousand, and should be the elite of Qin State.

At that time, Qin Ershi refused to face the reality that everyone in the world rose up to revolt, and hid in Qin Gong, still singing and dancing, deceiving himself. Therefore, there was no large-scale conscription to the whole country. Coupled with the fierce power struggle within the Qin empire, a group of important ministers left by the first emperor were persecuted, made mistakes in decision-making, and missed the opportunity to suppress the uprising again and again, which led to the instantaneous collapse of the Qin empire.
