Why is Zhuge crossbow created by Zhuge Liang lost?

Because the word "ju" means capital in ancient Chinese, that is to say, ten arrows are fired at once. Therefore, some experts believe that Zhuge Liang's crossbow can shoot ten arrows continuously and quickly, and it is illustrated by the arrows in the Warring States period. However, from the reality, it should be the first one. Because the kinetic energy that the crossbow can provide at one launch is limited. When ten crossbows are fired at a time, the kinetic energy allocated to each crossbow will be reduced to one tenth of the original. However, because Zhuge Liang's crossbow has been lost in later generations, it is not clear whether the "Ten Arrows" here can shoot ten arrows at a time or continuously.

There are only a few words about Zhuge Liang's improved crossbow, and it is impossible to verify whether Zhuge Liang's improved crossbow fired one arrow or ten arrows at a time. But according to speculation and modern experimental research, Zhuge crossbow can only shoot ten arrows in a row. In Zhuge Liang's "History of the Three Kingdoms", there is only one sentence about crossbows: "Bright and clever, gains and losses are even crossbows, all of which are unexpected; Wei Chunqiu said: It is also a kind of crossbow. If you lose iron, you will lose eight inches. If you lose a crossbow, you will lose it ten times. However, because the crossbow arrow has no feathers, the iron arrow will lose its balance and roll when flying for a long distance. The wooden arrow shaft requires high accuracy and is difficult to manufacture by hand, so it is not easy to manufacture and use in large quantities. After the Ming Dynasty, due to the rapid development of firearms, crossbows were no longer taken seriously.

Zhuge Liang's crossbow was first seen in the History of the Three Kingdoms. Zhuge Liang of Shu made a crossbow, also called crossbow. It can fire ten arrows at a time, but its size and weight are too big for individual soldiers to use. Mainly used to defend cities and camps. That kind of burst is not the same as machine guns, but it can punch continuously, which still has certain lethality to infantry phalanx. Large legions don't need to aim, and the accuracy is not high.
