Since the bow and arrow will not work. Then use a crossbow. Although the range of the crossbow is not as good as that of the bow and arrow, the lethality of the bow is definitely stronger than that of the bow and arrow at close range. The arrows fired by the crossbow are short and thick, the center of mass is in the front of the aerodynamic center, and the arrows are easy to fall when flying in the air.

Moreover, the crossbow is also a stable shooting platform, and there is no need for strong arm support after the bow is opened, so it is easy to aim and thus the hit rate of the crossbow is higher.

It is precisely because of this that crossbow arrows are more suitable for tiger and leopard cavalry. After all, bows and arrows require a certain amount of skill, and it takes a long time to train them to be successful. Especially on horses, which require a long period of training. A soldier like a white horse and an archer requires years of training, but the tiger and leopard rider never has such time. If you give them a few years to develop, the daylily will be cold.

When it comes to crossbows, Zhao Fei thinks of a crossbow that is famous in later generations, that is, Zhuge repeater. Zhuge Repeater is a kind of repeater made by Zhuge Liang of Shu during the Three Kingdoms period, called the Yuan Rong crossbow, which can fire ten arrows at a time, and the firepower is very strong, if the tiger and leopard can be equipped with such a thing, it will definitely be able to sweep any army.

However, according to legend, the Zhuge crossbow invented by Zhuge Liang is quite bulky, and it is difficult for ordinary infantry to hold it. The so-called Zhuge Repeater can only be placed on the city wall or camp for defense.

Later, the great inventor Ma Jun wanted to improve it and make it a kind of fifty-arrow crossbow, which was more powerful, but because the production was very complicated, the arrows used had to be specially made, so it was not produced in large quantities and was later lost.

And for this kind of lost thing, Zhao Fei naturally has nothing to do. However, for Ma Jun, Zhao Fei was very interested. Ma Jun is one of the most famous mechanical inventors in the history of ancient Chinese science and technology.
