Ancient Chinese history is a history of war, from the Spring and Autumn Warring States to the Qing Dynasty, the dynasties have fought countless battles, and weapons are more and more advanced, although now the army uses hot weapons, such as automatic rifles, sniper rifles, pistols, submachine guns, heavy machine guns, etc., but in the era of cold weapons, China has a weapon called the king, this weapon is the Tang Dynasty period of the strange knife, the Tang Dynasty in the face of the northern cavalry when the use of strange knives can be broken.
Mo dao is a kind of cold weapon of the Tang Dynasty, in the Tang Dynasty, in order to fight against the Turkic cavalry, the Mo Dao came into being, Zhenguan four years, mo dao from the Jianghuai region to Chang'an, and later assembled the Tang Dynasty army, when the Tang Dynasty military god Li Jing turned the Mo Dao into a standard weapon, this is also because the Tang Dynasty lacked warhorses at that time, can only use weapons to make up for their own deficiencies, when the Tang Dynasty army and cavalry were engaged, once the enemy entered within 150 steps, the crossbowmen began to shoot crossbow arrows, and the other side began to shoot bows and arrows when they entered 60 steps. Once the opponent is 20 steps closer, then the strange knife can come in handy.
Regardless of whether the other side is heavy cavalry or light cavalry, once they encounter the strange knife, they will definitely be crushed, and once the cavalry loses the advantage of impact, there is no difference with the infantry, so the power of the strange knife is very powerful, it is the tang dynasty's divine weapon against the cavalry, Tianbao 14 years, the AnShi rebellion broke out, the Tang Dynasty in order to quell the rebellion, sent the great general Li Siye's strange knife team to send troops, at that time An Lushan's troops will definitely lose the battle once they encounter the strange knife team.
But the process of the strange knife is very complicated, the Tang Dynasty has adopted the local quenching technology, but also the use of soil burning method, in addition to the use of composite steel process, that is, in the middle of the two layers of low carbon steel sandwiched a piece of high carbon steel, so that the weapon created is more resilient, and later the Technology of the Tang Knife was sent to Japan after the Tang History Society was sent to Japan, which has become a popular samurai sword in Japan.
After more than 1,000 years of development, the technology of the strange knife has long been lost, because the cost of the strange knife is very large, so the Tang Rulers stipulate that no matter who is not allowed to use the strange knife as funerary products, after the fall of the Tang Dynasty, the Song Dynasty was unable to equip the Strange Knife on a large scale, and later used spears, axes and other weapons to restrain the cavalry, but unfortunately such a divine weapon was finally lost in the long river of history, and it has to be said that it is a pity.
