Seeing that Lu Xiaoyu was so interested in cast iron, it was rare to find such a bosom friend, and the other party was a noble county horse, of course Ou Jiansheng knew everything and said everything. He popularized science to Lu Xiaoyu www.biquge.info that at the beginning of the Shang Dynasty, some people used natural meteorite to forge iron. By the middle and late Spring and Autumn period at the latest, the ancestor Ou Yezi had begun to smelt steel. When he arrived in Southern Chu, Emperor Wen of Southern Chu implemented a laissez-faire policy, and the steel smelting and casting industry developed rapidly. Because steel utensils have obvious advantages over other materials (such as stone, wood, copper, etc.), the demand for them has increased greatly.

"What, sir, are you saying that your ancestors already know how to make steel?" Lu Xiaoyu now respectfully calls Mr. Ou Jiansheng and humbly asks him for knowledge about iron smelting. When he heard that his ancestors had started making steel, he was shocked. He himself thought that this local method of steelmaking did not exist, but he didn't expect that it could already be made into steel in Nanchu, and it should not be false from Ou Yezi's descendants.

"That's right, it seems that you know about steelmaking as well. Although it has existed before, many people do not know how to make steel because of the disappearance of our Ou Clan, which is the inheritance of our unique skills. ”

"Sir, are you saying that you don't make steel now? This is a big loss for the army, this steel is much harder than ordinary pig iron, and the soldiers can have more protection and fewer casualties. ”

"Junma, I didn't expect you to know about this steelmaking as well. To tell you the truth, the steel smelting and casting industry used to be a lucrative profession. I think that at the beginning, smelting and casting families like ours were all rich, and their wealth was worth thousands of dollars. But as a result, because of the invasion of the Yi people in the north, the court was helpless against them, but blamed our ancestors for not forging a weapon that could effectively resist the Yi iron cavalry and raided our home, and the people were forced to flee to this mountainous land. Until recently, King Wu Yue got the news out of nowhere and arrested me. I hate the people of the Southern Chu royal family as much as my ancestors, so even if I am caught, I just want to fool and forge some defective products. Ou Jiansheng also has an upright personality, he recognized that Lu Xiaoyu would not tell himself to King Wu Yue, and said all the thoughts in his heart.

It is really a smelting family, and this casually built weapon seems to be exquisitely crafted in Lu Xiaoyu's eyes, which may be the real ingenuity.

Lu Xiaoyu immediately gave Ou Jiansheng a big salute, "If the Southern Chu royal family did anything to hurt the Mr. family before, I am willing to apologize for them and compensate for Mr.'s loss." It's just that now that the national disaster is at hand, I hope that Mr. can think about the common people in the world, smelt steel and make hard weapons to drive Beiyi out of the Central Plains. Count me Lu someone to ask for Mr. ”

"Junma, you can't do it. It was really an honor for King Wu Yue to have such a good horse. However, I don't hide it from Jun Ma, this Beiyi's iron cavalry is indeed very powerful, and ordinary armor and iron swords can't do anything against them, as long as they fight hard to rush into battle, they can break up the formation in an instant, and they can't resist it in a hard shield. Ou Jiansheng said helplessly.

"What if you change to a new type of weapon and a new type of armor?" Lu Xiaoyu added the good steel plate he wanted to use to his cloth armor, and explained that it was a light cloth armor used with his own explosives, Ou Jiansheng was quite shocked, he didn't expect Lu Xiaoyu to have such an idea. Immediately told him all the secret methods of steelmaking.

Originally, the steelmaking method used by Euclidean was evolved from the cast iron softening technique developed by Ouyezi. Through long-term and repeated practice, Ou Jiansheng has an in-depth understanding of the mechanical properties of pig iron that change with the level of carbon. In practice, he was able to decarburize cast iron with a carbon content of about 4% or more to eliminate the structure of the white iron in the inner layer, and the whole body became high-carbon steel. In this way, an advanced process has been created to turn pig iron into steel through high-temperature decarburization in the solid state.

Lu Xiaoyu applauded Ou Jiansheng, as a person who understands basic chemical reactions and steelmaking attempts, Ou Jiansheng's method of local steelmaking is indeed feasible, but he is not a professional and cannot open his mind to come up with this method. As soon as Ou Jiansheng finished speaking, Lu Xiaoyu immediately realized.

"It turns out that this is the method of decarburizing cast iron into steel."

"Do you even know the name of the horse? Truly a man of God. Ou Jiansheng's eyes widened and he couldn't believe that Lu Xiaoyu even knew the name of the steelmaking method he had painstakingly studied for many years, it was simply amazing.

With Ou Jiansheng's advanced steelmaking technology at that time, it was easy to make steel plates. According to Lu Xiaoyu's request, Ou Jiansheng forged a steel plate loaded with cloth armor in high agreement, and found craftsmen to put it into production on a large scale. Lu Xiaoyu then asked Wu Yue's garment division to make cotton cloth into a cloth armor coat. Just wait for both sides to be completed and then they can be combined into a complete piece of cloth armor. He specially designed a pattern of the head and wings of the Flying Tiger Army as a logo on the cloth armor, so that every soldier of the Flying Tiger Army felt proud and confident.

Finally, looking at the complete cloth armor made, it is not as heavy as ordinary armor, and it is also designed to be refined and slimmed, which is more convenient for the soldiers to move in battle. Even Ou Jiansheng, who was only in charge of steelmaking, finally asked Lu Xiaoyu to ask for a gift for him, which shows the popularity of this cloth armor.

Lu Xiaoyu and Han Xin put on it first, and tried the two pieces they had just completed on their bodies, and Lu Xiaoyu was quite satisfied. Han Xin looked at the cloth armor on Lu Xiaoyu's body and then at the cloth armor on his body, and always felt that something was wrong.

"Big brother, you and I are wearing the same cloth armor, how to distinguish the level of the position in the army, there must be some difference, otherwise it will not be a mess. Both generals and minions are dressed the same. ”

"Oh, I didn't think about it, I didn't think it through. It's too late to change now. By the way, there is a way. Lu Xiaoyu drew on the drawings the epaulette marks of various military ranks in modern times, ranging from private to general. You only need to add it to the shoulders of the cloth armor when the time comes, you are really a genius, you can think of it, Lu Xiaoyu is quite narcissistic about his thoughts. After listening to Lu Xiaoyu's introduction, Han Xin also agreed greatly, which was much more concise and clear than carving complex patterns on each piece of armor and making all kinds of armor representing different official ranks.

Lu Xiaoyu and Han Xin couldn't put it down, so they directly wore it back to the palace.

And Xiang Yu in the palace, after being poured ecstasy soup by King Wu Yue, fell asleep for three days and three nights. Now that he finally woke up, he felt like his head was about to burst, pressed his painful head hard, walked out of the door, and secretly scolded King Wu Yue in his heart for being despicable and trying to find him to theorize, and he was also a man who was not drunk for a thousand cups. How could it be that after drinking a few glasses of wine, it must be King Wu Yue who was the obstruction, and he felt a little uneasy when he saw that he was not in a big problem now. How could he know that all his secrets were revealed by King Wu Yue with the ecstasy wine that could confide the truth. And when he was asleep, King Wu Yue was intensively carrying out the "Qingjun Side" operation to unite the other six kings.
