In the smelting workshop, Zhao He and Le Yi were still standing there.

The so-called heavy armored cavalry, I think General Le Yi should have some ideas, right? Zhao He asked.

Le Yi thought for a while and said: The king meant that the soldiers were wearing armor like Wei Wushu, and rode on horseback to fight against the enemy with swords?

Zhao He smiled and said: Your statement is basically correct. However, the armor of Wei Wuzhu is actually unqualified. The so-called "If you want to do a good job, you must first sharpen your weapons. In order to form a stronger heavy cavalry, Da Zhao needs stronger armor, which is what I am bringing you here today.

Wei Wuzhu's armor was still unqualified? Le Yi was a little surprised.

You should know that the armor of the Wei Wushu is a three-level armor, which is a total of three layers of protection inside and outside.

Such excellent protection was also an important factor in the invincible battle of Wei Wuzhe in the early years of the Warring States Period.

Although the Wei State has declined now, the Wei Wushu has always been regarded as a benchmark for heavy infantry.

Now, the king actually said that Wei Wuzhu's armor was not qualified?

This inevitably made Le Yi a little curious about what kind of armor could satisfy Zhao He.

After thinking about it, Le Yi suddenly felt that he understood: Could it be that the king knew the Chu people’s steelmaking method?

As the saying goes, steel is not divided. Since it can be refined, it is not strange to refine steel.

In the Warring States Period, there was a method of steelmaking, and this method of steelmaking was called carburizing steelmaking.

The so-called carburizing steelmaking means placing the block of iron into hot charcoal for a long time to heat it, allowing the surface of the block of iron to penetrate into the charcoal, and then forging into carburizing steel sheets, then folding and forging the multi-layer carburizing steel sheets, then quenching and normalizing it repeatedly to finally obtain satisfactory steel.

However, this technology was only controlled by the Chu people and the Yue people. After South Korea seized Wancheng, the steelmaking base of Chu, South Korean craftsmen also learned the steelmaking method, and Yan Kingdom in the late Warring States period also learned this method.

Handan is also a big city for smelting, but Zhao State will not do this cutting-edge technology of the era.

Zhao He smiled and said: No, no, no, what is so strange about the Chu people’s steelmaking method? What I want to show you today is the steelmaking method that transcends the entire era!

The carburizing and steelmaking method mastered by Chu Yueyan is of high quality.

In "The Book of Exiling Guests", Li Si mentioned that Qin Shihuang had six treasures, one of which was the Tai'a Sword, which was jointly cast by two major sword-casting masters Ou Yezi and Mo Ye, and was smelted by carburizing and steelmaking.

However, the disadvantages of the carburizing steelmaking method are also very obvious. Its production efficiency is low and the requirements for craftsmen are very high. It is suitable for a few elite craftsmen to cast very sharp and rare weapons, and is not suitable for large-scale production.

Zhao He said seriously: Today, let me show you the method of steel frying after careful research!

At this moment, a lingering voice came.

Unexpectedly, in addition to military and national affairs, my son even involved this smelting method, which really surprised the widow's father.

Zhao He turned his head in surprise and found that his master's father was standing not far away, accompanied by Fei Yi Xinqi and the others.

Zhao He was a little surprised: Why is the master’s father here?

The master's father smiled and looked at Zhao He: It's nothing, the widow's father is actually here to see what kind of thing can make Wang Er abandon military and national affairs and marriage affairs and run to this smelting workshop.

Obviously, the master's father was a little dissatisfied with Zhao He's incompetence in his work.

Zhao He was slightly stunned, and then he naturally figured out the joints.

He glanced at Fei Yi and Xinqi next to his father. Is it one of these two guys who complained?

Fei Yi and Xinqi coughed at the same time, and looked up at the sky at the same time.

Two old slippers!

Zhao He cursed in his heart and smiled: The master's father misunderstood. My son is here today, for

Made a new generation of armor for the Longxiang Army, especially for your heavy cavalry. The master father waved his hand and said: Although the widowed father gave you all the state affairs, the widowed father would not have become a blind man. Now, take out your things and show them to the widowed father.

Fei Yi hurriedly smoothed out: Master Father, this new thing always takes some time. It is better to come and watch it in a few days, so as to give the king some preparation time.

The master father snorted and said: The enemy will not give Da Zhao time, the widow father will see it now!

Zhao He glanced at Fei Yi speechlessly, "My good teacher, why do you say this smooth things over like causing trouble?"

Also, Master, I am making contributions to Zhao State. Why do you feel a strong sense of finding faults?

But it’s right to think about it. Do you need a reason to get angry with your son?

Fortunately, I was prepared.

Zhao He reached out and pointed forward.

Master, this new smelting method, I named it - the steel frying method!

The Lord Father looked in front of him and found a large pond with red hot iron. Some people were stirring with big sticks and pouring powder into the pot.

In the distance is a large iron stove, and several laborers are working hard to blow the wind and the heat waves are gushing. After standing for a while, it makes people sweat profusely.

This molten iron comes out of the furnace and through the pipes.

It's that simple? The Lord Father is a little confused.

Zhao He smiled and said: If it is too complicated, how can it be produced on a large scale?

The so-called steel stir-frying method is to heat pig iron with coal or coke charcoal and other charcoal fire to a semi-liquid liquid state, and stir the iron continuously like cooking, and blow it with a blast furnace, and sprinkle it with an appropriate amount of ore powder to reduce the carbon content of pig iron to the steel composition range.

Although it seems simple, it was summarized by the Chinese craftsmen who took dozens of generations to develop step by step.

If it weren't for Zhao He's advantage as a time traveler, this technology should have appeared in the late Han Dynasty.

In other words, this technology is at least four hundred years ahead of this era!

Zhao He was full of confidence and said with a smile: Master Father, it’s not just a boy who boasted. When Da Zhao used the armor he created here in the future, Master Father would know its benefits.

The master father glanced at Zhao He, snorted, and said: "It's no basis, how do you prove it?"

The Lord's Father felt that his son might be really a little bit arrogant.

You said that you are going to do diplomacy, war, and power struggles, which are what you, a king, should do.

Now, what kind of steel stir-frying is coming?

No matter how good this thing is, can it be more useful than doing the job of a king?

Besides, a young man who grew up in the deep palace knows what kind of smelting?

I'm afraid I got some specious things from somewhere, so I used them to offer treasures.

It's a waste of money and troubles!

The Lord Father made up his mind that today, he must beat this son well.

Facing the question of the Lord's father, Zhao He was full of confidence and smiled and said: Lord's father, please come with me, the finished product is right in front of me.

Behind the Lord's father, Xinqi glanced at Fei Yi and whispered: Fei Xiang, do you think, what kind of steel-fried King can really succeed, right?

Fei Yi looked calm: It will naturally happen.

Xinqi was stunned: Fei Xiang is so confident?

Fei Yi nodded and followed the Lord's father.
