As we all know, the development of science and technology in ancient China is very rapid, especially in the forging of cold weapons, as early as the Spring and Autumn Warring States period, China's ancestors discovered the cast iron softening treatment technology, when most of the weapons used in various countries are bronze, but after the discovery of this technology, the rest of the countries have used iron as a production tool, to know that Western countries have only studied this technology in modern times, I have to say that the wisdom of the ancestors is really powerful.
Ancient casting weapons are relatively poor toughness, easy to break, but as long as the iron is heated for a long time, and then the carbon change occurs, it can change the material and performance of the iron, so that the cast weapons are sharper and more durable, and there are many emperors in history who have their own famous weapons, such as the Tai'a sword of the King of Chu, the Lulu sword of Qin Shi Huang, and the Chixiao sword of Han Gaozu Liu Bang, but the weapons used by the martial generals are much more domineering, the most famous of which is Lü Bu's Fang Tian painting sword.
Fang Tian painting halberd is an ancient heavy weapon, the top is like a tic-tac-toe type, generally used in the imperial palace honor guard, not this weapon can not be used in actual combat, but the requirements for use are relatively high, if it is not a person born with divine power, it is impossible to use the Fang Tian painting halberd, in history, there are only two people who use the Fang Tian painting halberd, one is Lü Bu, one is Xue Rengui, for Lü Bu, everyone knows that he is the first military general in the Three Kingdoms period, even Guan Yu, Zhang Fei, Liu Bei three people can only fight with him.
Xue Rengui was a famous general of the Tang Dynasty, he used the Fang Tian painting halberd when he went out to Liaodong, such as entering the no-man's land, taking the first rank of general in the million army, and later more than three arrows fixed the Tianshan Mountain, the god bravely collected Liaodong, and was named the Duke of Pingyang County by the emperor, although the "Water Margin" also mentioned that there were also Shi Wengong and Fang Jie who used the Fang Tian painting halberd, but the "Water Margin" is mostly fictional novels, not historical records, so it will not be repeated here.
In fact, the strongest cold weapon in ancient China is not the Fang Tian painting sword, but the Tianlong broken city halberd used by Xiang Yu, according to legend, this weapon is forged by meteorites outside the sky, forged for 9 days and 9 nights, Xiang Yu is relying on this weapon to cross the world, invincible, but in the Chu-Han war, Xiang Yu finally defeated Wujiang, killed himself, and a generation of overlords ended up like this, making posterity sigh.
But these weapons are used by individuals, the strongest cold weapons used by the ancient Chinese group army is still the Strange Knife of the Tang Dynasty, in the early years of the Tang Dynasty, due to the lack of war horses, had to work the weapons, and then the Strange Knife came into being, if the infantry is equipped with a Strange Knife, it can be advanced like a wall, the people and horses are broken, even if the other side is a cavalry, there is no way, but these casting processes are finally lost, and now the casting process of the Japanese samurai sword is learned from the Tang Dynasty, not all of which are ironic.
