Fujikasa appeared in "Romance of the Three Kingdoms", which was extremely powerful.
Seven hundred miles to the southeast, there is a country called the Country of Ugo. The lord of the country has a vulture bone, a long body, does not eat grain, and feeds on snakes and beasts; he has scales and armor, and the sword and arrow cannot invade. His soldiers wear rattan armor; their vines are born in mountain streams and coiled on stone walls; the Chinese people take it, soak it in oil, and take it out half a year; they are dried and re-soaked, and more than ten times before they cause armor; when they wear it, they do not sink across the river, and they do not get wet through the water, and the swords and arrows cannot enter.

The power of the Tengjia Army mainly comes from the Tengjia: first of all, the defense is extremely strong, the swords and guns are inaccessible; secondly, it can be used as a tool to cross the river, in the southwest region with many rivers, which greatly increases the flexibility of the troops, that is also the biggest foreign aid and killer skill of Meng Yue, who can stand it?
Sure enough, the Shu army fought with the Tengjia army and was defeated, and the general Wei Yan was beaten to autism. In the end, Zhuge Liang was clever and had already thought of countermeasures. After introducing the Tengjia army into the Pansnake Valley by deception, he attacked with fire, defeated the Fujijia army and captured Meng with seven shunshi to pacify Nanzhong.
I have to say that although Zhuge Liang won, he also paid a big price. That vine armor army was so powerful, why did Zhuge Liang not form one later?
The first is the issue of production time and raw materials. The production process of rattan armor can be said to be very cumbersome. To use a specific vine, you also need to soak in the oil for a long time, take it out and dry it and then soak it, repeat it dozens of times. It seems that in a short period of time, it will certainly not be possible to create vine armor.
Can Zhuge Liang still wait a long time before carrying out the Northern Expedition? Moreover, the vines produced by this product are grown in specific mountain streams, and the yield is certainly not high, and if you want to mass-produce them on a large scale, I am afraid that the raw materials are not enough.
The second is the issue of technology inheritance. The vine armor is very powerful, but the key is that Zhuge Liang does not know how to make it. In the Battle of Pan Snake Valley, a large number of vine armor soldiers died, and they were not many in number themselves, and they did not know how to make vine armor.
Now Zhuge Liang was shy to ask for the secret recipe for vine armor? Without saying a word, definitely not giving! Of course, there is also a way, that is, to directly introduce the vine armor soldiers. This method will definitely not work, I think the introduced Fuji armor soldiers will directly rebel and surrender to the State of Wei...
Finally, there is the issue of climate variability. Rattan armor is a tropical equipment, made of high-quality rattan, good breathability, and can also cross the river. However, after Zhuge Liangping returned to the south, he wanted to go north and fight against the State of Wei. Look at the main combat sites of Zhuge Liang's Northern Expedition, most of which are in Shaanxi, Gansu and other places, belonging to northern China.
Although it is not particularly north, it also belongs to the middle temperate zone, and the northwest wind that whistles is blowing, and the winter is definitely very cold. This weather wearing rattan armor? There is also a war, and the light freezes to death. And I highly doubt that the performance of the rattan armor will be greatly disturbed by the cold weather, even if it is barely put on, the performance is not so good.
All in all, specific problems should be analyzed on a case-by-case basis. Just like the Tibetan mastiff is fierce on the Tibetan Plateau, but it cannot be used as a police dog in the plains. Therefore, although the vine armor is a good equipment, it is really not Zhuge Liang's dish!
