To understand this, Zhang Chong first needs to know how Deng Zhi forges armor pieces now.
Deng Zhi replied:
"It is said that a piece of armor must be forged a hundred times to make it strong. To make a piece of armor, it must be forged at least a hundred times, otherwise it will be too soft and brittle to be able to defend against swords."
After finishing speaking, Deng Zhi happened to see a furnace of iron being smelted in the crucible and it was cooling there.
He walked directly to the crucible, picked up a piece of cooled iron with iron tongs, and showed it to Zhang Chong. At this moment, the iron was like a noodle, soft and soft, not at all as hard as people think of iron.
Zhang Chong naturally understands the reason. He has knowledge of junior high school chemistry. This is because iron contains too many impurities during smelting. The iron at this time can be called iron-carbon alloy.
Then Deng Zhi began to ask his apprentices to set up the bellows and light the fire in the forging furnace. He wanted to forge the piece of iron in front of Zhang Chong. Normal forging required two people, one to use tongs and the other to forge with a hammer. But Deng Zhi's arms were amazingly strong.
He used the pliers with his left hand and the hammer with his right hand to continuously forge the iron ingot.
After more than a hundred blows, the iron ingot was hammered into thin slices. Just when Zhang Chong thought that this was the first forging, Deng Zhi used pliers to fold the thin iron piece in half, and then continued to hammer, and then this was the first forging.
Zhang Chong was stunned. It turns out that's the case. No wonder a hundred-forged sword is worth a thousand dollars. Such a method would take a lot of effort. Of course, Deng Zhi had no intention of striking any sword. After three forgings, he started to let it sit. He didn't know.
Leave it there for how long, and then use pliers to put the iron bar into clean water to quench it.
At this moment, Deng Zhi had time to talk to Zhang Chong. He walked out of the hot forging shed and was covered in sweat as if he had taken a shower. He said to Zhang Chong:
"Qu, this water is from several nearby rivers. I have found the lake water that is most suitable for quenching. You may not know that the quenching effect of different lakes is very different. But when it comes to the best, it is river water, which is more suitable.
"
Deng Zhi also said:
"When we beat out the iron bars, we must let them go for a while. This is called cold treatment in our industry. Time is very important. Only experienced craftsmen can grasp the time. There are some things that the master has not mentioned, otherwise
Without waiting, the iron bar was quenched in water as soon as it was hammered, and the iron bar that was finally forged collapsed. So, this ironworker has to learn from the master, and it is useless to work behind closed doors."
Seeing that Zhang Chong was not impatient with what he said, he got excited and continued:
"This quenching effort is to make the sword strong. Water and fire combine to make the sword strong. There is Longquan water in Xiping, Runan, which is most suitable for quenching swords. When it is quenched, the sword will be strong and sharp. Therefore, the sword made of Longquan water,
They are all extraordinary. I heard that the Qingzhang River in the north is good water and can also be used to temper swords. But the Han River and Fu River must not be used to temper swords, as the water is weak."
Deng Zhi pointed to a few barrels of grease next to him and continued:
"In addition to quenching with lake water, it can also be quenched with grease and brine, but the effects are different. I heard that some knife makers also use the drowning of five animals for quenching. The smell is too strong and I don't like it. If you use
If it is quenched with grease, the sword will be more tough and will not break easily. But what is the use of this?"
Deng Zhi picked up a forged knife from the knife rest and gestured to Zhang Chong:
"The iron material requirements for each part of this knife are different. The most important thing for the blade is to be strong, so that the blade will not be damaged, so it needs to be quenched with clean water. The back of the knife needs to be tough, so that the knife can last a long time.
"
Zhang Chong has learned a lot this time, and he is really grateful to Jisun for sending such a real master craftsman. The so-called master craftsman means that he knows what is happening and why it is so, so that he can continue to innovate in practice.
Then Zhang Chong put away his desire to point fingers, knowing that in this area, he, Zhang Chong, was the younger brother, and he must not commit the bureaucratic style of commanding experts in a professional field.
The next thing focused on how to make iron armor faster. Zhang Chong also discovered that in fact, the forging process is now very mature, but the reason why it is so laborious is because steel is hard to find in smelting.
Zhang Chong knows that the difference between iron and steel is the carbon content. He has heard of a relatively fast method of obtaining steel, which is the steel filling method.
In fact, it is forged with pig iron wrapped in wrought iron. Although it still requires forging, the number of forgings is much less than that of hundreds of forgings. But there is a key point, which is that the ratio of pig iron to wrought iron is different. Zhang Chong has never done it.
Ironworkers don't know this ratio either.
He could only tell this method to Deng Zhi and let him try it himself. In fact, this was also the reason why Zhang Chong wanted to establish this iron official institute, which was to make technical reserves so that when the technology was established, production capacity could be exploded.
Otherwise, how long will it take to equip an army with just one armor-maker?
Deng Zhi listened very carefully. He had long discovered that Qu Kui often said some very inspiring ideas. Although they were just ideas, they would indeed become more efficient after he put them into practice.
For example, coal smelting allows him to smelt molten iron. Later, he will modify the iron smelting furnace so that the molten iron can flow out directly, so that the smelting furnace can be used uninterrupted. Unlike now, he has to wait for a wave of smelting.
It takes half a day to cool down before starting the next wave.
Here, Zhang Chong walked around a few more times, and finally found that there was really nothing to say, so he returned with Cai Que, Guo Zu and other soldiers.
He was going back to Dazhai, where Duman was about to report to him the affairs of the village during this period.
----------------------------
At this time, in the wine shop in Dongpingling, Xun Yu was crouching in the opposite building with Qingnu and a group of county soldiers. Here, the situation in the wine shop was fully understood.
In their line of sight, a short, fat man was shouting at the bartender:
"It's still the same as before. Give Mr. Naigong a bushel of millet, two pounds of pork, and three ounces of pulp. It will be faster."
After receiving the instructions, the apprentice hurriedly started to go to the kitchen to give instructions.
Seeing that this man was defenseless, Xun Yu asked Qing Nu in a low voice:
"This person went to Jian Geng with Zhang Chong, are you correct?"
Qing Nu bowed and nodded:
"Hui Langjun, it's absolutely true. I've been keeping an eye on him for a long time. I can't be wrong."
Why is Qingnu here?
It is said that since he abandoned Zhang Qiu and escaped alone, he has never dared to return to Dashangli. He knew that the most ruthless person in Dashangli was not Zhang Qiu, the eldest man, but Zhang Hong, the third elder.
During this period, he worked as a mountain lodge, as a domestic helper, and even as a nearby ranger, but who would lead a person who doesn't know his background?
Therefore, Qingnu was always unhappy, crying about hunger and cold, and had no fixed place to live. But even so, he was still caught by Zhang Hong.
At that time, he was sleeping in a broken temple. A sack was put on his head, and then he was brought to Zhang Hong.
Before Zhang Hong could say anything, Qingnu told Zhang Hong everything that happened that day. When he said that Zhang Suo had killed Zhang Qiu, Zhang Hong, who had been squinting, fell silent. At this moment, he was older than before.
After Qingnu finished speaking, he closed his eyes and waited for death.
He said this not in the hope of surviving, but in the hope that he would suffer less. But the development of the matter exceeded Qingnu's expectation. Zhang Hong did not kill him, but said to Qingnu:
"Qingnu, now that you are no longer my slave, you can change your name back to Yinli. You have been with me for so many years, and you have tried your best to do this. I won't kill you, but there will be no relationship between you and me.
Enyi. I will recommend you to a noble person later, follow him carefully, and don’t go back to Dasangli in the future."
When Qing Nu heard this, he felt as if he had been struck by lightning. He was speechless for a moment and could only shed tears and kowtow to Zhang Hong's back.
After that, Qingnu, oh no, it was Yin Li, was recommended to Xun Yu by Zhang Hong, and he followed Xun Yu specifically to be responsible for the intelligence of the Taishan bandits.
And the person in the wine shop that Yin Li is following now is his biggest achievement during this period.
Yin Li knew before that the group of people who followed Zhang Chong to practice watch were not dead. Moreover, he was also keenly aware that Zhang Chong and his group should have a close relationship with the Taishan bandits.
I didn’t see it. It was said that the leader of the Taishan bandits was holding a banner with the word "Chong" and was known as General Shi. Although Yin Li still didn't believe that Zhang Chong was the Shi Jiajun, but with so much information, he had to take it seriously.
Treat this possibility.
And wealth was sent to him from heaven, so one day he wanted to recruit local knights in a wine shop. They usually hang out in the market wine shop.
But that day, he bumped into a person. He looked familiar, and then he suddenly remembered, wasn't this person Zhang Goudu?
I went to Jian Geng with Zhang Chong, but there was no news after that. Later, the whole family followed Zhang Gouzi and his family to Shigu Mountain.
Why is he here?
He had suspicions in his heart, but Yin Li became even more concerned. After that, he kept an eye on this person and found that this person would come to Dongpingling City to eat meat every now and then.
Yin Li was suspicious, where did this poor guy get his money?
After that, Yin Li reported the matter to Xun Yu. Without saying a word, Xun Yu took his father's talisman and ordered a group of county soldiers to capture this person.
For Xun Yu, what's the use of thinking so much? Take it directly, under three trees, what's not to say?
After the defeat of Dongpingling soldiers, Jinan Prime Minister Xunnui gave up on himself.
The two Qingzhou heroes that Xun Yu recruited for him were brought into the mansion by Xun Yu's bus, and they all had to deal with county affairs. Then they put themselves in a high cabinet and studied gracefully all day long.
Xun Yu, who wanted his father to become a dragon, knew that his father's heart was tied to the Taishan thief, so he volunteered to take the job of assassinating and raping the Jinan Kingdom. He wanted to see what the Taishan thief was like. In order to cheer up his father, he had to kill the thief.
No.
At this moment, on the wooden building opposite the wine shop, everyone was watching the rough man eating and drinking there. Some of them were aroused with greed, and their stomachs kept rumbling.
Xun Yu had his own way of doing things. He had already prepared food. At this moment, his disciples were already bringing baskets of boiled meat.
All the soldiers in the county screamed out in shock, but after all, they were the elite selected by Xun Yu. They knew the importance of this moment, so they all held back and waited for Xun Yu's orders.
Xun Yu took off the meat knife he wore on his waist, cut off a piece of white meat first, and put it into his mouth:
"eat!"
The soldiers of the county were no longer polite and started to look at the baskets of meat.
As expected, he is a young man who does things with dignity.
Seeing everyone eating, Xun Yu gave instructions:
"Don't take action in the city for a while. There are many eyes and ears in the city. We will wait for him to leave the city and capture him outside the city. Remember, we must capture him alive."
