Looking at the cavalry resting on the side, Teng Ying rushed back with his horse!

Le Cheng glanced at Teng Ying, bowed to the prince and said, "What does the prince think of the Daijun cavalry?" After hearing this, Zhang Xiao laughed and said: "The general asked me like this, I dare not speak!" ”

After the prince's words came out, Yu Xin and Wei Jia beside him were snickering! But Le Cheng's face was a little unbearable, thinking that the prince had a slight complaint about this, and he was about to prepare to say something to the prince again!

But listening to the praise of Taizi Peak: "In time, it will become a sharp blade for me to conquer the city and conquer the land. ”

After Le Cheng heard the prince's words, a smile appeared on his face, and Yu Xin stepped forward and said: "Fortunately, the prince's painting style has changed sharply, and the person in charge is about to see the general look at each other angrily!" ”

Zhang Xiao heard Yu Xin's witty words and patted Lecheng's shoulder...... And asked his colleague Zhuo Yonglai: "Zhuo Yong, have you ever seen the shortcomings of the saddle in this trial?" ”

After Zhuo Yong heard this, he hurriedly replied: "Back to His Royal Highness the Prince, this will take a while after the soldiers have been trained, and Yong will personally check them one by one before he can say it, at this moment, Yong dare not speak in vain!" ”

Zhang Xiao nodded in agreement and said, "What you say is reasonable!" ”

Le Cheng on the side saw that the purpose of this training had been reached, so he said to the prince: "His Royal Highness the Prince, since you have seen the benefits of the cavalry, let Zhuo Yeyin and others deal with the rest, and His Royal Highness the Crown Prince will invite ...... here."

After Zhang Xiao listened to Lecheng's words, he walked along. Pen? Interesting? Pavilion wWw. ｂiquge。 info This time he came, it's just a guide, if he really lets him train as a moral soldier again, I'm afraid he will also be out of luck!

Teng Ying, who stayed behind, glanced at Ye Yin, then threw a spur on his horse, pointed to a group of resting cavalrymen and shouted, "Don't you get up and continue training?" ”

The cavalrymen, who had been laughing, got up from the grass one after another, pedaled the saddle and got on their horses, and continued to repeat the back and forth galloping back and forth, gradually becoming more and more proficient......

Tang Que, who was watching, pulled Zhuo Yong, who was looking at it, and asked, "You expected this?" ”

After Zhuo Yong heard this, he shook his head and said: "Although I had a slight expectation, I never thought it would be so shocking!" ”

After Tang Que heard Zhuo Yong's words of praise, he also said with deep feelings: "Prince Dao is a god and a man, and it is becoming more and more unpredictable......

Zhuo Yong smiled and said, "Ugly people, how dare you be presumptuous? ”

Tang Que was stunned for a moment when he heard this, and then smiled like a big smile: "Haha, the Tao is Zhuo Sanye's reason......

Zhang Xiao walked into the general's tent with Lecheng, and after tasting the bowl of water, he said: "Today is also a clever try, the saddle and other equipment still need to be continuously improved. ”

Le Cheng pondered carefully, secretly sighed the prince's importance to the saddle, and said loudly: "Cheng Cheng immediately notified someone, it must be done if it is not a hit, and it is a blockbuster!" ”

After Zhang Xiao heard Le Cheng's words, he said: "It must be more general than hard work......

After some rhetoric, I saw Teng Ying and Zhuo Yong walking in! Zhang Xiao looked at it and asked, "But it's been handled?" ”

Zhuo Yong nodded his head and said: "It's not a big deal, after I looked at it with Tang Que, I thought that it could be controlled, and soon the horses in the camp could be fully equipped!" ”

Hearing that Zhuo Yong could quickly equip the whole army, Le Cheng got up and said to Zhuo Yong: "If there is no gentleman's ingenuity, how can there be such an achievement!" ”

Hearing Lecheng's praise, Zhuo Yong hurriedly waved his hand and refused: "Yong is just a map, if it weren't for the prince to draw a picture here, how could there be a saddle?" ”

Speaking of which, it turned to the prince again! Zhang Xiao also shook her head after hearing this, and smiled lightly......

And Zhuo Yong in the tent stepped forward and asked at this time: "Your Royal Highness the Prince, do you still remember the coal that you talked about with your subordinates?" ”

Zhang Xiao, who originally had an unintentional face, heard Zhuo Yong talk about the "black gold" at this moment, and asked with excitement on his face: "But it has been transported to the land of Xiaoshan?" ”

Zhuo Yong nodded and said, "Since Yong came the day before, it has just arrived, so I asked this question when I saw the prince today?" ”

Zhang Xiao knew that at this time, people made iron by direct reduction of ore, which had a very low carbon content and soft performance. It is melted at a lower temperature, cast, and annealed by heating to eliminate brittleness and obtain ductile cast iron devices.

Zhang Xiao got up and said to Zhuo Yong: "Previously, I told you about the difference between coal and charcoal ironmaking, the temperature of the two is different, resulting in different products!" ”

Although Zhuo Yong can be called a master in smelting, he still has a sense of strangeness to new things, Zhang Xiao saw it from his eyes: let you say a thousand things, if you don't practice it yourself, you just won't ......

Zhuo Yong slowly digested the prince's words, and asked, "If you use coal to make iron directly, what is the difference between what you get and the previous one?" ”

Zhang Xiao heard Zhuo Yong's simple question about this, so he thought for a while: "In the simplest way, the craftsman has less forging steps in the steps of striking iron, and the iron produced is less defective than before, and the hardness has become a little higher!" ”

When Zhuo Yong heard the prince's words, he was very surprised, and he knew that with the current method of making iron from blocks: iron ore should be reduced with charcoal in a solid state at a lower temperature to obtain iron with more inclusions. This kind of iron is a sponge-like solid, with many impurities, and the quality is soft, and it can only be forged, not cast. After heating and forging, extrusion of inclusions, and repeated heating process, it can be formed!

And after hearing these remarks today, if coal is used to make iron, it will definitely be able to change the current situation of short supply, and the prince also said that it can greatly reduce the defective products, which is really a great discovery!

And Zhang Xiao is deeply concerned about what Zhuo Yong said, the emergence of coal is not only the shortage of changed block ironmaking, but more importantly, coal has directly become a necessity of a new smelting technology - frying steel!

Stir-fried steel gets its name from the fact that it is constantly stirred during the smelting process, like stir-frying. The raw material of frying steel is pig iron, and the key point of operation is to heat the pig iron to a liquid or semi-liquid state, and use the method of sprinkling concentrate powder into the blower to oxidize silicon, manganese and carbon, and reduce the carbon content to the composition range of steel and wrought iron. Most of the products of fried steel are low-carbon steel and wrought iron, but if it is well controlled, medium-carbon steel and high-carbon steel can also be obtained.

Zhang Xiao didn't dare to expect to be able to forge steel, but if Zhuo Yong could ponder it here, he wouldn't know? At the very least, wrought iron is simply made if you go down to this point!
