The heavy cavalry rushed into the Wei army, which was even more terrifying than the plague, and the cavalry only had to charge on horseback, and the scimitar would automatically reap the lives of the enemy.

Under the powerful impact force, Wei Jun faced the scimitar, basically dying when he hit it, injured next to it, and even hitting the knife edge, his body could be split in two by the scimitar.

This is mainly due to the sharpness of the scimitar and the impact of the warhorse.

And this scimitar is made by the steel filling method.

There is a saying in China that it is called "100 tempered into steel".

It is to temper iron and make it steel.

Modern people know that the difference between steel and iron lies in the carbon content, the carbon content of pig iron is higher than that of steel, and the iron is calcined at high temperature, tempered and tempered to reduce the carbon content, and it becomes steel.

In the steelmaking method, there is the hundred steelmaking method, which uses this principle.

However, the 100-for-100 method is time-consuming and labor-intensive, and as the carbon content slowly decreases, the steel becomes tougher and tougher, and the forging becomes more and more difficult. It's called 100 steel, but it can't be forged 100 times.

In this era, the method of making steel is the method of 100 steelmaking.

Liu Chan came from later generations, so naturally he would not use such an ancient method again, so Liu Chan introduced the steel filling method.

The steel filling method only appeared in the Wei and Jin dynasties, while Qi Wuhuaiwen in the Northern and Southern Dynasties developed the steel filling method and created the famous Su iron knife.

Its method is to "burn pig iron to be heavy and soft, and several nights to become steel." Take soft iron as the spine of the knife, bathe with the drowning of five animals, and quench the fat of five animals. ”

First, the pig iron is melted and poured onto the wrought iron, so that the carbon permeation of the wrought iron increases the carbon content of the wrought iron, and then quenched into steel with animal urine and animal fat respectively. Livestock urine contains salt, quenching to cool this water quickly. The quenched steel is hard, and the steamed bun is cooled when quenched with livestock fat, so the steel is flexible.

After being treated with these two quenching agents, the steel is flexible, and the blade is both rigid and soft, and the Su iron knife created by Qi Wuhuaiwen in this way can cut more than 30 layers of armor, that is, cut off 30 layers of leather armor.

Too advanced technology could not be transported in this era, and what Liu Chan introduced was the steel filling method improved by Qi Wuhuaiwen.

The first weapon that Liu Chan created with this steel-filling method was a scimitar, which was used to equip Ma Chao's cavalry.

Because of the Northern Expedition, the cavalry under Ma Chao will be the main force, and in the north, there are mostly cavalry battles, and the cavalry has strong combat effectiveness, so it can occupy more advantages.

Historically, the Mongols marched across Asia, and the cavalry used scimitars.

Zhang He was defeated by Lin Yuan, and did not dare to continue the battle with Lin Yuan, so he had to hide in the rear and command. He looked at the invincible scimitar cavalry on the battlefield and muttered to himself: "How is it possible, how is this possible!" ”

Zhang He couldn't understand why the balance of the Han cavalry was so good, and why the weapons of the Han army were so sharp?

The soldiers of my Great Wei have to hold their horses' necks when they rush to kill, why can the cavalry of your Shu Kingdom free two hands?

An adjutant general ran over with a panicked face: "General, brothers can't resist it, the cavalry of the Shu army is too powerful!" ”

Zhang He knew that the formation was chaotic, and although he had a lot of soldiers and horses, it was impossible to turn defeat into victory, so he gritted his teeth and said: "Retreat first!" ”

Hearing this, the adjutant general hurriedly shouted: "Brothers, retreat!" ”

The sound of gold sounded, the Wei army was relieved, and hurriedly withdrew in the direction of the camp, and under the pursuit of the Han army, they lost their armor one by one, and were embarrassed.

When Lin Yuan saw the Wei army fleeing, he shouted, "Brothers, chase me!" ”

"Poor Kou Mo Chase!" Deng Ai hurriedly stopped Lin Yuan: "The enemy army still has tens of thousands of people, we can't pursue it, we should focus on the overall situation, if we lose, the camp will be difficult to defend!" ”

Lin Yuan snorted coldly and said, "Cheap them!" ”

Deng Ai ordered: "Clean up the battlefield quickly, everything must be brought back, and the stirrups must be taken off for the horses that died in battle." ”

"No!"

However, it was said that Sima Yi was encamping, and when he heard the shouting of killing, he hurriedly led the army to respond.

"The general retreats quickly, and I will lead the troops to break the rear!" Sima Yi lined up on the road to answer Zhang He.

Zhang He hurriedly led the army into the aisle, Sima Yi waited for a long time, and saw that the Han army did not pursue, so he led the army back.

In the big tent of the Wei army.

Knock Knock Knock......

Zhang Heniu drank a pot of water, slapped the kettle on the case, and drank: "It's really angry with me!" ”

Sima Yi asked: "General, you have 20,000 horses, and you have transferred shield soldiers and archers, how can you be so embarrassed?" ”

Zhang He explained with a calm face: "The Shu army somehow drummed up an armored horse, they were armoured, not afraid of bows and arrows, under its charge, our army's shield bearers could not resist, and they rushed into the formation.

Then came a heavy cavalry, armed with scimitars, extremely sharp, and did not slash, but held the scimitar horizontally, and charged on horseback, and our army suffered countless casualties, and even could divide people in two.

Moreover, among the Shu army, there is a small general who is excellent in martial arts, no less than Zhao Yun in Changbanpo back then, I am far from his opponent, and I was almost killed by him.

Now that Guan Zhang is old, Zhao Yun and Ma Chao are gradually getting older, I don't want Shu to have such a master, it's really annoying! ”

"Hiss......" Sima Yi gasped when he heard this: "This shouldn't be, the armored cavalry is extremely heavy, how can the soldiers maintain their balance when they charge?" A weapon made of 100 steel, even if it is a scimitar, cannot be so sharp. ”

Zhang He shook his head and said, "I don't know, they are very stable on the horse, and they don't even have to hug the horse's neck." However, I took advantage of the chaos to pick up a scimitar, which is indeed much sharper than 100 steel! ”

Zhang He said, took out a scimitar that he had picked up on the battlefield before from his back, pulled out the saber at his waist, and the two collided, only to see that the saber was suddenly broken into two, but the scimitar had no gap at all.

Sima Yi was shocked: "General, your sword, I remember that it is only sixty forging!" This Shu country is really evil, corn, sweet potatoes, back to the cannon, now this scimitar, how can there be so many novelties. ”

Sima Yi shook his head and said: "I hope that this scimitar will be difficult to build on a large scale, otherwise it will be a huge disaster for my Wei State, Zhong Da, you are in charge of the school affairs, didn't you find any news?" ”

Sima Yi smiled bitterly: "If I can find out the news, corn and sweet potatoes would have been planted all over my Dawei." ”

Zhang He sighed and asked an adjutant general, "How many men and horses have been killed or wounded in our army?" ”

The adjutant replied: "One thousand two hundred brothers did not return, and of those who came back, more than three thousand were wounded, and eight hundred of them were seriously wounded. And when retreating, thousands of people lost their armor......"

When Zhang He heard this, he slapped it on the table and shouted: "Hateful! Before our army could attack, thousands of people were killed and wounded! Hmph, when the road is repaired tomorrow, I will raise troops to attack the Shu army, I must make them look good. ”
