67, the mighty armor of many people in later generations know that Hebei is the largest province of our Chinese iron and steel, and Zhuo County is located in the border of Hebei, there is a huge iron mine, this is still Su Shuang and Zhang Shiping, the two horse merchants told Bai Ziyun, originally this pair of good friends wanted to buy this mine, secretly smuggled iron, and now worship Bai Ziyun as the lord, and this lord clearly stipulates that it is not allowed to fornicate with other races, so he lost this mind and dedicated the location of the iron mine.

When Bai Ziyun found out, he was immediately overjoyed, and hurriedly sent Zhang Su and the two to buy the iron mine, in order to facilitate mining, they also made explosives + drugs, and after spending a few days personally guiding a few blasters, they sent people to mine.

At the same time, during this time, Bai Ziyun drew a blast furnace design for the construction team to build. Bai Ziyun's blast furnace design drawing is not very difficult, the principle is actually very simple, some chemical knowledge, this thing can basically be made after a period of exploration.

In the blast furnace, iron ore, coke and limestone are poured from the top of the furnace and preheated air is blown from the tuyere located at the lower part of the furnace along the perimeter of the furnace. The carbon in the coke at high temperature is combined with the carbon monoxide produced by the combustion of oxygen in the air, and the oxygen in the iron ore is removed during the rise in the furnace, so as to reduce the iron to obtain iron. The molten iron is released from the iron mouth. The reduced impurities in the iron ore combine with fluxes such as limestone to form slag, which is discharged from the slag port. The gas produced is exported from the top of the furnace and used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers, etc. after dust removal.

Blast furnace steelmaking has begun to face elimination in modern times, and is about to be replaced by electric furnaces, but in the era of the late Han Dynasty, it is definitely a high-tech product, and the steel that can be produced is afraid to be called a miracle.

The construction team looked at Bai Ziyun's drawings, asked a few questions that they didn't understand, and immediately started construction, the construction team after more than a month of college construction, has a very high experience in construction, under Bai Ziyun's personal guidance, the blast furnace was quickly completed.

Because the smoke emitted by the blast furnace was very thick and polluting, Bai Ziyun built the steel mill in a remote place in Zhuo County. Originally, it was a manor house, which happened to be used as a factory site and a dormitory for craftsmen.

Yan Zhaozhi has a lot of subway ore, but there are also many impurities in the iron ore, in the ironmaking process, there are many problems, such as more sulfur, the pig iron is very brittle and other problems, fortunately, Bai Ziyun has a complete set of steelmaking technology, which is extremely detailed, and these problems are quickly solved. After a few days, the craftsmen of the steel mill learned how to use the blast furnace and then smelted more than ten tons of pig iron.

So much molten iron was produced so quickly, so that several blacksmiths were extremely excited, and began to work hard to direct their apprentices to make steel, their steelmaking is the method of frying steel, that is, using a hammer to constantly beat a piece of red-hot wrought iron, with the continuous beating, the charcoal in the wrought iron is consumed, and then the rest is steel.

From the perspective of future generations, the Chinese people can proudly say that our steel frying method is hundreds of years ahead of Europe and the United States, but for people like Bai Ziyun, this laborious method is enough to hurt eggs. Bai Ziyun looked at it for a while, and then he was not interested in watching it, and immediately stopped them from doing it, but ordered these craftsmen to make a converter.

Because Bai Ziyun has a detailed steelmaking process, although the equipment is a little simpler, the quality of the steel smelted is not much worse than that of the blast furnaces of later generations.

Bai Ziyun's blast furnace is not big, and it can only train 20 tons of pig iron every day, but it is already a terrible thing in this era, and I am afraid that it will shock the world if it is spread out. Steel has always been a weapon of the country, and if those in the imperial capital know about it, it will inevitably be a trouble. Therefore, Bai Ziyun strictly forbade the spread of the word, and sent domestic slaves to guard the surroundings, and craftsmen were not allowed to go out, and outsiders were not allowed to enter.

Fortunately, these steel-making craftsmen are all domestic slaves purchased by Bai Ziyun, although the work here is a little harder, and there is no freedom, but the food is all the delicacies of the fairy world, and you can also practice the exercises of the fairy world, you can prolong your life, and you will not be invaded by all diseases, basically everyone is satisfied, not to mention that the master also said that he will stay here for a few years, which is not a long time.

Because the cost of steelmaking has dropped significantly, and the output is high, it is fully capable of configuring the soldiers with long swords on a large scale, of course, there is no need for this, in terms of use, the sword on the battlefield is not as lethal as the knife. However, the sword has been the main blade on the battlefield since there were bronze weapons, and it is rich in different cultural meanings, and it is a symbol of power. Many students love to use a long sword as a weapon, and those high-ranking generals in the army are naturally not exempt from vulgarity.

In the Han Dynasty, due to the craftsmanship and cost, the weapons commonly used on the battlefield were still long weapons such as "ge, spear, and halberd", because the cost of these weapons was much lower than that of swords, because less metal was used, and the production of zuò was much simpler. The kind of sword with a lot of complexity of the process of making zuò is only prepared by those generals, and the ordinary soldier is at most a "ring head knife", this kind of "ring head knife" is relatively simple compared to the sword, and only needs a single-sided blade, and does not need a complex process, so the short blade of the Han army is mainly a "knife" as the main weapon. Whether it is a slash or a stab, the wound surface caused by a knife is much larger than that of a sword.

A few days later, Gongsun Chan walked into Bai Ziyun's quiet room and saw a set of silver-white armor standing beside Bai Ziyun, with a silver light flickering and eye-catching.

"Chan, meet the master!" Gongsun Chan saluted respectfully.

"Hmm!" Bai Ziyun nodded slightly, and then asked, "Bogui, how is your White Horse Yicong training today?" How many centaurs are there? ”

"Master Yu, my white horse is now 3,000 people, each of them is white and white, and they have all practiced the master's dragon elephant prajna gong, and now everyone's strength has increased by dozens of catties, and they have practiced the Five Tigers Broken Door Sword Technique, and their martial arts have made great progress, but they lack armor and are worse in protection." Gongsun Chan replied humbly.

"What do you think of this armor?" Bai Ziyun asked with a smile as he pointed to the armor beside him.

Gongsun Zhan looked at the silver armor for a while before he said, "This armor is powerful in appearance, powerful, and extremely beautiful, but I don't know how to defend it." ”

This silver armor is made by Bai Ziyun according to the image in the film and television dramas and games of later generations, with a tiger head on the left, opening his mouth and whistling, vivid, and the plate armor is also equipped with beautiful patterns, with a powerful and domineering atmosphere. The abrasives for making this armor were not yet capable of being made by craftsmen in this era, and it was Bai Ziyun who personally made them, but it took him a lot of time.

Although the armor of this image shocked Gongsun Zhan, an ancient, it also gave him a feeling that it was not very practical, so he looked at the armor with hidden doubts.

"You can draw your sword and try it!" Bai Ziyun said with a smile, although this is his game, he also hopes to be recognized by others.

"Yes!"
