Qin Yeyu fought against the Confucians, and the news spread all over Luoyang that day and spread to the world.

It turned out that that person was not only good at force, but also so perverted in terms of literary attainments, and the scholars in the world were shocked.

When the national thief became Qin Ye, it also set a historical precedent. Not only physically, but also mentally struck the heavenly scribes.

When Dong Zhuo learned about this, he laughed and called him a great sage.

After Qin Ye returned to the barracks, he saw Pu Xiang.

Qin Ye is now in charge of military quarters and is Pu Xiang's top boss. Pu Xiang didn't dare to face Zhang Liao's fiery temper, but he still complained, "General Qin, the time to build a steel knife can make dozens of wrought iron knives. No one had ever asked for all the soldiers to be equipped with steel knives, and there was simply no supply. ”

Pu Xiang said the details, not that he was unwilling to build it for Qin Ye, but that the steelmaking process was complicated. The time to provide Qin Ye with a thousand steel knives was enough to renew the wrought iron knives for the entire Dong Zhuojun.

"I see." Qin Ye asked, "How do you make steel?" ”

Later, I learned that after the iron was burned red, I smashed it desperately. Because of this process, it requires a lot of manpower and material resources.

Pu Xiang said: "If it is wrought iron, our Pu family has mastered the refining technology of dissolving iron, and one person can make more than a dozen or even dozens of knives a day. ”

"Do you know what iron-melting technology means?" Pu Xiang asked.

"Isn't that just melting iron?" Zhang Liaodao.

Pu Xiang sneered, "It's just as the name suggests." ”

"It's too simple." Qin Ye said casually: "It is to heat the pig iron to melt or basically melt, stir it in the furnace, and use the oxygen in the air to melt the carbon and other impurities contained in the pig iron, so as to obtain wrought iron." ”

Pu Xiang was dumbfounded, this is a newly developed new technology. In fact, blacksmiths have thought of iron-melting technology for a long time, but they cannot meet the requirements of removing impurities in molten iron, and can only make raw iron utensils in batches, and wrought iron still needs to be manually forged to eliminate impurities.

It is only recently that the technical problem of removing impurities has been successfully solved, but only wrought iron can be smelted, and steel cannot be reached.

Zhang Liao and the others breathed a sigh of relief, fortunately the general knew, if not, he was really stumped.

However, Qin Ye was very puzzled, "This is the steel frying technique, why don't you extract steel from it?" ”

"You can also think of extracting steel from molten iron?" Pu Xiang was surprised and said: "All the famous craftsmen in the world are studying the steel frying process, but they are still in the experimental stage. My Pu family is in the forefront, but it has not been successfully developed, and now it can only be smelted wrought iron. General Qin, when you say that you fry steel, I'm afraid it's just hearsay rumors, and there is no one in the world who can fry steel, I'm sure. ”

Pu Xiang is very proud, his Pu family is the world's leading craftsman. His Pu family can't study it, let alone others. This self-confidence, he still has it.

The main difference between pig iron, wrought iron and steel is the carbon content, iron with a carbon content of more than 2% is called pig iron. Iron with a carbon content of less than 0.05% is called wrought iron. Iron with a carbon content of 0.05%-2% is called steel.

In ancient steelmaking, iron ore was generally smelted into a sponge-like solid block in a furnace, and then taken out after the furnace was cold, which was called block ironmaking. Iron smelting has low carbon content, soft texture, and many impurities, which is the method of smelting wrought iron.

If you want to make steel, you also need to use ironmaking as raw material, heat and absorb carbon in a carbon fire to increase the carbon content, and then after forging, remove impurities and infiltrate carbon to obtain steel.

Since the carbon content of steel is in the middle, it is difficult to grasp the problem of steel when it is turned into molten iron.

Nowadays, although molten iron can melt a large amount of wrought iron at one time, it still cannot be turned into steel. It still needs to be forged by a hundred refining methods, and carbon is infiltrated, and the steel is still time-consuming and labor-intensive.

However, after all, Qin Ye was through the crowd and well-informed, and he still remembered some techniques before returning chemistry to the teacher. "It's still very simple to remove impurities that have infiltrated the carbon."

"What?" Touching his beard, he pulled off several sticks, "It's simple?" ”

A young man named Pu Yuan, who came with Pu Xiang, was already stunned at the moment. Simple? This general, do you know how many years our Pu family has been studying this? For fifty years, it was not studied. How old are you?

Pu Xiang was very dissatisfied, thinking that Qin Ye was pretending to be face-saving, "Then tell me, how to fry steel?" ”

Qin Ye smiled faintly, "Why should I tell you?" ”

In the later period of the Three Kingdoms, the method of frying steel was gradually perfected, and the first person to master this technique was a person named Pu Yuan.

And for a long time after the Three Kingdoms period, frying steel was still a new technology, and most blacksmiths had not yet mastered it. In "Zhuge Liang's Biography", there is a record of Pu Yuan casting a knife for Zhuge Liang at the mouth of the sloping valley. It has a description of 'Neodym Fabricator, Special Anomalous Method'.

After the knife was cast, in order to test the quality, Pu Yuan asked the soldiers to fill the bamboo tube with iron beads, raise the knife and cut hard, such as cutting grass, the bamboo tube was broken and the iron beads were cracked, and people praised the steel knife cast by Pu Yuan as the 'magic knife' that could "cut gold and jade, and sharpen iron like mud".

Even in the Three Kingdoms game, there is also a weapon with a force bonus such as a magic sword, which can be seen.

Pu Xiang was suddenly embarrassed, this kind of technology is a secret of each family, so he said that the process of wrought iron is very different from each family, and no one will tell anyone.

Zhang Liao and the others were stunned, they didn't expect the general to understand steelmaking, is there anything they don't understand?

However, Pu Xiang thought that Qin Ye was exaggerating, and he could use the word secret to cover everything anyway. Pu Xiang's temper came up, especially in steelmaking technology, how could he let Qin Ye's empty words be suppressed.

Pu Xiang was very annoyed, and said forcefully: "If the general can tell the reason, my Pu family is willing to be a famous craftsman of the Qin family for thirty years." ”

That is, selling yourself for thirty years.

In the long history of thousands of years, the improvement of smelting technology has been calculated over hundreds of years. The Pu family has obtained a peerless craft, and they are willing to work for Qin Ye for 30 years without suffering at all. On the contrary, the Pu family can always lead the world's famous craftsmen in the next hundred years.

"Thirty years ......." Qin Ye pondered, and it seemed that he would not suffer a loss.

After all, he can't be a blacksmith, and to master this technology, he also needs people to produce.

Qin Ye cleaned up his mind and said calmly: "In this way, let's go to your Pu family's workshop first and have a look, and then I will consider whether to accept your conditions." ”

This is a field trip, after all, such a good technology cannot be given to a craftsman who has no scale and no ability, and it also needs to be matched.

Pu Xiang almost pulled it when he heard it. There is still someone who wants to test the strength of our Pu family? Do you know that if our Pu family thinks that they are second, there will definitely be no blacksmith in the world who dares to say that they are first.

"Good!" Pu Xiang got up suddenly, and went to take a look, when the time came, this young man couldn't say why, and it was only him who was ashamed.

"Uncle, if he really has skills, wouldn't our Pu family want to be a slave of the Qin family for thirty years?" Pu Yuan, the young man who accompanied him, began to be apprehensive.

Pu Xiang regained his composure and self-confidence, "If you don't believe in yourself, you have to believe in the power of our Pu family." The power of our Pu family can't be studied, he is a seventeen or eighteen-year-old boy, can he study it? He's not a god? But he himself has to be careful, this matter will spread and ruin his reputation. ”

"Uncle is right." Pu Yuan was categorical and no longer worried.
