Archaeological findings show that in fact, as early as the Warring States period, the State of Chu invented the crossbow. Zhuge Liang was not the first. There are many restored models in modern times, but none of them are completely consistent with historical records.
In ancient books, the record of Zhuge crossbow is like this. "Zhuge Liang Chuan" said that "Ming is smarter than wisdom, and the profit and loss are even crossbows, all of which are unexpected. Deduct the art of war and make an eight-array map, which is salty. " Quoting Wei's Spring and Autumn Annals, it is said that there are eight rules, seven precepts, six fears and five fears, all of which are used to guide Li Chaochen. This is also a profit and loss crossbow, which is called Rong Yuan. It takes iron as the vector, and the vector is eight inches long. "
Zhuge Liang's crossbow must shoot ten arrows at a time, and the energy is scattered, so the range of the arrows is bound to be reduced, and the power is also small, but it is by no means one tenth of that of ordinary arrows, because the combined weight of ten profit and loss arrows should be similar to or even lighter than that of a bed crossbow, and the strength of the crossbow is the same as that of the arrows, even if the power is scattered, the power is quite large.
Some people think that it should be more like a crossbow. The main reason is that if ten arrows are fired at the same time, and all of them are fatal, there seems to be no problem in principle, but it is difficult for the materials at that time to reach this strength. If it shoots ten arrows at the same time, it is difficult to become a weapon for individual use.
