After Qin Shihuang's reunification, he began to fight against the surrounding Xiongnu who were good at riding and shooting. Under the high-speed charge of the war horse, it was difficult for ordinary Qin infantry to resist, so the craftsmen of the Qin Dynasty developed a weapon called crossbow. Qin crossbow not only has strong attack power, but also is easy to carry. According to relevant data, the effective attack distance of Qin crossbow is150m. Soldiers can install crossbows without much effort, and the power of Qin crossbows should not be underestimated. Paired with Qin crossbow is a three-headed crossbow, which not only has strong penetrating power, but also can relieve air resistance well.
According to the excavation of Terracotta Warriors and Horses Pit, in addition to the crossbows with extremely strong lethality, there are also large crossbows in Qin Dynasty, which are irresistible to human beings whether attacking the city or charging, and experts have also seen an incredible project from these weapons, that is, all crossbows and crossbows can be disassembled and reassembled. In other words, even if your crossbow is broken on the battlefield, as long as there are spare parts next to it, it will remain intact, and you have to feel the wisdom and strength of Qin craftsmen.
What about the Tang Dynasty? The Tang dynasty was not weak, at least in terms of overall strength, much better than the Qin dynasty. At that time, when Tang Gaozong conquered Liaodong, the army assembled 500,000 people, while the number of soldiers guarding the border during the Tang Xuanzong period reached 600,000. In terms of comprehensive strength, the Tang Dynasty was the best feudal dynasty in the history of China.
First of all, the military service system was adopted in the Tang Dynasty, that is, the state cultivated land for the people and the people joined the army when the country needed it. In peacetime, the militia can do anything to raise pigs and farm land. As long as the court needs it, they have to immediately put down their hoes and receive formal training to protect their country and defend their country. The advantage of this is that the Tang court does not have to spend huge sums of money to support the army. When there is no war, soldiers don't have to stay in the barracks at all Therefore, Datang's financial expenditure has left a lot of money.
Secondly, during the Tang Dynasty, the war was no longer keen on cold weapons. With the discovery of alchemists, gunpowder gradually showed its power in the Tang Dynasty, not just fireworks, which Qin Bing could not match.
So what would happen if Daqin's army collided with Datang's army? The number of the two sides is basically the same, but the army of the Tang Dynasty is obviously more monolithic, because not all the Qin soldiers are from the State of Qin, including those generals. In terms of weapons and equipment, Qin Jun has extremely lethal crossbows and crossbows, while Tang Jun has artillery and rockets. On the power, the latter is relatively large, and Tang Jun may not be able to resist it in front of the crossbow, but the operation of not carrying the crossbow is complicated, and it takes a long time to replace the crossbow, and the artillery is ahead of the crossbow in all aspects.
So the end result is the downfall of Qin Jun, not to mention Tang Jun's weaponry, which has been upgraded by countless versions compared with the Qin Dynasty. Under the confrontation, the weapons of the cockroach are not enough.
