"Come in!"

As soon as Wang Zongwei entered the office, he saluted and said, "Commander, I have a problem here that needs to be solved urgently, but I have been unable to think of a good solution, so I want to ask you."

Qing Cang was reborn and traveled through time. As we all know, the civilization of his era must be much higher than that now, so it is right to ask him some questions.

"Oh? There is any problem that makes you feel that it cannot be solved, let's hear it."

"That's right. Recently, a batch of iron-made weapons have suffered a lot of losses, such as rust and fracture. I counted today's battle and there were gaps in a total of 100 weapons. The captured Yellow Turban Army's weapons were even worse and the quality could not keep up. Small problems can be solved, but some problems such as gaps are equivalent to re-melting. The ones made are still not used a few times, which consume a lot of losses on the materials and high labor costs."

The durability of weapons has a lot to do with smelting technology. Techniques such as steelmaking were rare in the Eastern Han Dynasty.

"Oh? Have you brought the sample here?"

"Yes, please take a look!"

Wang Zongwei took out a few big knives, and a few hook and sickle spear tips and put them on the table. Qing Cang saw that as he said, a big knives had cut out the gap and the blade was no longer sharp. The hook and sickle spear tip was even more fierce, and the hook and sickle had been folded back and spread out directly. This situation would occur. There are two possibilities: one is that there are too many impurities in the iron, and the other is that the carbon content is too high, which looks very brittle and is easily broken.

The carbon mentioned here directly determines the quality of the iron tool. When the carbon reaches a certain amount, it becomes steel.

Iron is divided into pig iron and wax iron. Steel and pig iron are both iron-carbon alloys, which are differentiated by the amount of carbon content. Generally, those with carbon content less than 0.2% are called wax iron or pure iron, and those with a content between 0.2-1.7% are called steel, and those with a content above 1.7% are called pig iron. Fried iron is soft, has good plasticity, is easy to deform, has low strength and hardness, and is not widely used; pig iron contains a lot of carbon, is hard and brittle, and has almost no plasticity; steel has the advantages of pig iron and wax iron, and is widely used by humans.

Blacksmiths who know this kind of relationship are mostly masters, but in modern times they are just ordinary blacksmiths.

"Commander, if nothing is wrong, let's first study this book "Shennong Bencao Jing"."

Guan Xiaofeng and others were still in the office, but Qing Cang suddenly forgot about it.

"Okay, thank you for your hard work, I hope you can study that book thoroughly!"

"Yes! Then let's go first!"

The five of them saluted a military salute and went out.

Qing Cang once again studied these weapons. If in modern times, these weapons were not qualified as agricultural tools. How could such weapons go to the battlefield?

If you want to do a good job, you must first sharpen your weapons. This shows how important the weapons are.

During the Eastern Han Dynasty, a large number of weapons of iron products were used, and bronzes were rarely used. In fact, weapons of iron products were already available as early as the Warring States Period. Some people may ask why not use bronze as a weapon, at least it will not rust and look good. The disadvantages of bronze are too obvious. It is much heavier than iron, and its hardness is not enough and too brittle.

Why are the Bronze Age weapons all swords? When the Iron Age weapons all turn into swords? It is because the bronze is too brittle and cannot be chopped and can only be used to stab.

Another important thing is that the iron reserves are surprisingly high, which means that iron is cheaper and easier to obtain.

"If this is the case, let's go to the blacksmith shop. Maybe there is a solution."

The root of all this lies in the place where these iron tools are produced, so he wanted to go there to find the reason. He didn't know how much iron smelting reached during this period.

"Yes! Commander. I'll take you to see."

Qing Cang carried his ak47 with him with him, rode his dark horse, and took dozens of guards to the north of Julu County.

He held a torch in his hand and looked around while rushing. It was already night. It was so quiet that it was so quiet that it was brightly lit in the east. At this time, the army and others were caring. Compared to that, this place was simply a piece of quiet land.

After walking for about ten minutes, I heard the sound of thugs, which disrupted the peace of the night. I made a single place here for blacksmith shops to facilitate processing and making weapons at night, and would not disturb the people.

On the way, Wang Zongwei introduced that there were 100 blacksmith workers in the entire blacksmith shop.

Wang Zongwei got off the horse and stopped the blacksmiths. "Stop, the commander will arrive!"

When these people heard Qing Cang come, they stopped their actions and gathered together. Qing Cang said that there is no need to kneel down in front of him. Because in modern times, we have never seen ordinary people kneel down to worship soldiers.

So these people did not kneel down, but showed a surprised expression on their cheeks. How could this supreme leader of Julu County come here to inspect today?

In this cold weather, the blacksmiths in Qing Cang's eyes were exposed, wearing only a pair of shorts. The muscle lines on their bodies were very clear, and their shoulders were covered with muscle lumps. The temperature here was extremely high, and red iron blocks were everywhere.

"Xu Dezhi, come out."

At this time, a big man walked out of the crowd, with dark skin and a long-lasting face hidden under his messy hair. He was Xu Dezhi, who was mentioned by Wang Zongwei, the leader of the blacksmith shop here, and the captain of the blacksmith shop.

They belong to the employment system, and Qing Cang spent money to make weapons. They were like employees of a company, and he was the boss. In order to facilitate management, a captain was selected from these people. Xu Dezhi was the captain.

Xu Dezhi replied: "Here!"

Qing Cang asked, "Your name is Xu Dezhi?"

Xu Dezhi replied carefully: "Yes, commander."

Qing Cang was extremely vivid in people's mouths. Today, he was inevitably a little scared when he saw him for the first time. Because he had a dangerous aura.

Xu Dezhi glanced at the ak47 behind Qing Cang, and his eyes never left for a long time.

Qing Cang discovered this, took the gun and handed it to him.

"Xu Dezhi What material do you think I made of this weapon?"

Weapons? People look at the ak47 and don’t understand at all. How could this be a weapon? It doesn’t have a knife edge and is not long. If you hit someone, it may hurt a little, but as a weapon, the difference is too far. These are based on people’s understanding of cold weapons. Compared with the age of guns and cannons, their knowledge is still less.

Xu Dezhi carefully took the ak47. As soon as the gun came to his hand, the gun was closed directly. It can be seen that the gun fell into the hands of others and they could not use it. Qing Cang then handed him to Xu Dezhi so reassuringly.

Xu Dezhi put it carefully in his hand and looked at it, and couldn't let it go. After a while, he said, "This is made of smelting iron."

Xu Dezhi's vision is indeed extraordinary. Although this ak47 is not all made of steel, Xu Dezhi can see the materials and explain the reason. It is very likely that he knows similar smelting methods.
