dusk.

The sun went down the other side of the oak tree, and the slanted light shone among the trees, and the leaves became bronze. The sunlight under the tree spread out like a golden tablecloth, and the yellow-green fields in the distance were gradually submerged in a blurred silent sinus.

And Cao Chong and others arrived.

This is a group of bandits wearing armor. Each of them has a sharp weapon, either a spear, a big knife, or a spear, and it is different.

This is their different places, and their same places are the decadence and anxiety on their faces.

There are not many people in this group, but there are also many, about 500 people, half of whom are middle-aged people, and the rest are children aged 11 or 2, as well as veterans in their forties or fifties.

"The bandits of the people will receive it, and I will pay homage to the nobles."

Cao Chong stood in front of him, touching the bridge of his nose with his hand. If his eyes were particularly looking at Kou De, it seemed like he was looking at some strange treasure. Kou De had been knocking on the ground for a long time and did not dare to look up, so he had to lie on the ground awkwardly, as if he was trying his best to control his breathing.

"Kode, do you know your guilt?"

Huh ~

Kou De took a deep breath, straightened his back, but his body shivered.

"The villain knows the crime."

Knowing guilty?

"Do you know what crime you committed?"

Kou De was stunned and had to say with a bumpy and bumpy voice: "The villain doesn't know."

He really doesn't know that there is still a mistake in living honestly. Why is this world like this?

"Then I will tell you that you have committed a death sentence!"

capital offense?

"Fart!" Kou De stood up immediately and angrily pulled out the long knife from his waist, but Gao Yi stopped it first.

"The noble man is wronged!"

There is no threat, but the enemy has to shout for justice.

"What are you wronging? How can the laws of the Han Dynasty be a joke?"

As soon as Cao Chong said this, the old lady couldn't stand any longer. He walked forward two steps and walked in front of Cao Chong. His face was obviously angry with Cao Chong.

"The noble man has said something about it, and now he cannot ignore it!"

Cao Chong smiled and continued, "Of course, I can't kill anyone."

Hearing Cao Chong's promise, the old lady's face looked a little better.

"Li Zheng should not breathe a sigh of relief, I have a request."

Require?

Lao Li and Kou De mentioned it in their hearts and asked, "What are the requirements for noble people?"

Cao Chong thought hard, but after a long time, he pretended to be enlightened and said, "I'll ask a few questions first, can I?"

Ask a question?

Kou De and Lao Li looked at each other, and both of them saw the slightest expression in each other's eyes.

There are only a few questions, as long as you don’t kill someone, everything is easy to say.

"Do you sell iron ore or fine iron?"

"This..." Kou De hesitated for a moment, and after seeing Lao Lizheng's permission, he said: "The big head is iron ore, and the small head is fine iron."

"Why do you think you can refine pig iron here?"

There is nothing to deny about this, so Kou nodded and admitted it directly.

"Who should I sell it, how often should I sell it, and how much should I sell it at a time?"

Kou De glanced at Lao Li, but the latter began to wink him. Unfortunately, although Kou De knew that Lao Li had something to say, he didn't know what Lao Li was about to say, so he had to answer Cao Chong's question honestly.

"Most of the time, it is sold with Xiliang merchants. The transaction is once a month, and one car of fine iron and thirty iron ore is once."

"A car?" Cao Chong was not very familiar with this unit of measurement.

"How many fine iron can a cart be made? How many big knives can be made?"

Kou Di's eyes rolled. At this time, he didn't see Lao Li's anxious expression, so he said, "You can make fifty knives in a car."

Fifty, that is to say, a car once a month is a transaction with two or three hundred ring-headed swords.

"Do you know who the Xiliang merchants trade with?"

Kou De shook his head, then added another sentence, saying, "I have heard him say the word "Chang'an Fufeng."

Chang'an?

Fufeng?

Ma Chao?

Cao Chong shook his head and rubbed his nose hard. After a while, Cao Chong waved his hand at Kou De.

"Give gold!"

Immediately, a tiger soldier was holding a plate behind him, and there were two golden lumps on it.

These two golden lumps make more money than they earn by selling iron ore for a month!

"Thank you for the gold!"

Kou De knelt down quickly, his vigilance towards Cao Chong decreased a lot, and a flattering smile appeared on his face.

Since ancient times, wealth has moved people's hearts and control them, so naturally they cannot be full of swords and weapons.

Cao Chong's move immediately made Kou become honest, and his face also looked better with Lao Li and the bandits behind him.

"This is the first time this time, but it is definitely not the last time. As long as you complete this young master's mission, this kind of reward will never be missing!"

"No!" Kou De naturally bowed his head and obeyed the order.

"From tomorrow, I will train a car of fine iron every day, can I do it?"

One car a day?

Kou De showed a look of embarrassment on his face.

"What, no?"

Kou De nodded and said, "We are just a steel-frying method, and we can't practice it so quickly."

Steel frying method?

Cao Chong was stunned and then seemed to have thought of something.

Ancient steelmaking technology in my country was invented in the late Spring and Autumn Period. From the pre-Qin period to the middle and late Western Han Dynasty, the main steelmaking process was block iron carburizing method; from the Han Dynasty to the Ming and Qing Dynasties, the main steelmaking method was steelmaking method and steel filling method, followed by the Hundred Steelmaking method and iron cooking method, and there was also "cast iron decarbonized steel" during the Han Dynasty, Wei Dynasty, Southern and Northern Dynasties, and there was also crucible steelmaking method in the Han Dynasty.

The steel frying method is one of the most famous methods of iron and steel making.

The earliest steel-making metallurgy technology in the world so far is the steelmaking method. It was invented and widely used in the early Western Han Dynasty.

The raw material for stir-frying steel is pig iron. The key point is to heat the pig iron to liquid or semi-liquid, and use blowing or sprinkling concentrate powder to oxidize silicon, manganese, and carbon, and reduce the carbon content to the composition range of steel and iron.

But at this time, Cao Chong had some questions. This steelmaking method is used to practice steel, so how did pig iron come about?

"I'm asking about iron making, not steel making."

Iron smelting?

"pig iron?"

Cao Chong nodded.

"Cat iron can also be used as a weapon?"

Pig iron contains a lot of carbon, hard and brittle, and has almost no plasticity. If you make a weapon, it will be broken after a few cuts. This is a weapon that cannot be made. People like Cao Chong cannot make iron, right?

"No need to worry about it, you just need to tell me, if it is pig iron, how much can you make?"

Kou De hesitated for a moment and said, "If it is pig iron, one car a day will not be a problem!"

"Okay!" Cao Chong was overjoyed. He really found a treasure this time!

"Then you will be a car a day. In addition, if the Xiliang merchant comes again, you can detain him and wait for me to leave!"

Kou De hesitated for a moment, but looked at Cao Chong's face and had to bite the bullet and agree.

"promise!"
Chapter completed!
