To understand this, Zhang Chong must first know how Deng Zhi forged the armor now.

And Deng Zhi replied:

"The so-called hundred forged into rigidity. If you want to hit a piece of armor, you must forge it at least a hundred times, otherwise it will be too soft and brittle to prevent the sword."

After speaking, Deng Zhi happened to see that the crucible iron-making furnace had made a furnace of iron, 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, this iron is like a noodle, soft and soft, and there is no hardness of iron in people's cognition.

Zhang Chong naturally understands the reason, the knowledge of chemistry in junior high school, this is that iron contains too many impurities in smelting, and iron at this time can be called more iron-carbon alloy.

Then Deng Zhi began to ask the apprentice to raise the bellows and light a fire in the forging furnace, and he was going to forge this piece of iron in front of Zhang Chong. Normal forging requires two people, one to make pliers and one to forge with a hammer. But Deng Zhi's strength was amazing, directly using tongs with his left hand and hammer with his right hand, constantly forging this iron ingot.

After hitting more than 100 times, Shengsheng hammered the iron ingot into a thin piece, just when Zhang Chong thought that this was a hundred forgings, Deng Zhi folded the iron sheet in half with pliers, and then continued to knock, and then this was a forging.

Zhang Chong was stunned, I see, no wonder a hundred forging treasure knife is worth thousands of dollars, such a practice takes a lot of effort. Of course, Deng Zhi didn't mean to hit any treasure knife, after the three forgings, he began to stand, and I don't know how long he put it, and then he used pliers to put the iron bar into the water to quench.

At this time, Deng Zhicai had time to talk to Zhang Chong, and he walked out of the hot forging shed, as if he had taken a bath, and he was sweating. He and Zhang Chong said:

"Canal, this water is the water I have experimented with several nearby rivers to find the most suitable lake water. You may not know that the quenching effect of different lakes is much worse. But if you want to talk about the best, you still have to go to the river, and that's right."

Deng Zhi also said:

"Let's hit the iron bar, we must put it down, this is called cold treatment in our industry, this time can be particular, you have to be an old craftsman to grasp the time. Some of the things that were not mentioned by the master, or they were not treated cold, the iron bar was quenched in water as soon as it was laid, and finally the iron bar that was finally forged collapsed, so ah, this ironworker, you have to learn from the master, and it is useless to build a car behind closed doors."

Seeing that Zhang Chong did not have any impatience with what he said, he became excited and continued:

"This quenching effort is for the sake of a strong sword, and when water and fire are combined, this knife becomes a strong knife. There is a dragon spring water in Xiping, Runan, which is most suitable for quenching swords, quenching out, and its sword is sharp. Therefore, the sword of Longquan water is not ordinary. I heard that the Qingzhang water in the north is also good water, and it can also quench swords. But the Han water and the Fu water must not be used to quench the sword, the water is weak."

Deng Zhi pointed to a few buckets of grease on the side, and continued to introduce:

"In addition to quenching with lake water, you can also quench with grease and brine, but this has different effects, I heard that some knife makers also use the drowning of five animals to quench, the smell is too heavy, I don't like it. If it is quenched with grease, then the sword will be more resilient and will not break when it is idle. And what's the use of that?"

Deng Zhi picked up a forged knife from the knife holder and gestured with Zhang Chong:

"The iron requirements for each part of this knife are different, and the most important thing about this blade is to be strong, so that the blade can not be broken, so it should be quenched with clean water. And the back of the knife needs to be tough, so that the knife is durable." ….

Zhang Chong has seen this wave for a long time, and he is really grateful to the sacrifice grandson for sending such a real master. The so-called master craftsman is to know what it is and why it is true, so that he can continue to innovate in practice.

Then Zhang Chong put away his thoughts about pointing fingers, knowing that in this area, he Zhang Chong is a younger brother, and he must not commit the bureaucratic style of commanding experts in the professional field.

The rest of the matter focuses on how to make the iron armor faster. Zhang Chong also discovered that in fact, in the forging process, it is now very mature, but the reason why it is difficult is because in smelting, it is rare to find steel.

Zhang Chong knew that the difference between iron and steel was this carbon content, and he had heard of a relatively fast way to get steel, that is, the steel filling method.

In fact, pig iron is wrapped in wrought iron to forge, although it is also forged, but the number of forging is much less than that of 100 forging. But there is a key in this, which is the ratio of pig iron to wrought iron

The case is different, Zhang Chong has never done ironwork, and he doesn't know this ratio.

He could only tell Deng Zhi this method and let him try it himself. In fact, this is also the reason why Zhang Chong wants to establish this iron official office, that is, to make technical reserves, and after the technology is formed, the production capacity can be exploded.

Otherwise, just relying on one armor builder, when will it be possible to equip an army?

Deng Zhi listened very seriously, he had already discovered that Qu Kui often said some very enlightening ideas, although it was still just an idea, but after he practiced, it would indeed be more efficient.

For example, the coal smelting made him able to smelt molten iron, and later he had to transform the molten iron furnace to let the molten iron flow out directly, so that he could use the smelting furnace uninterruptedly. Unlike now, refining one wave has to wait for half a day to cool down before starting the next wave.

Here, Zhang Chong turned around a few more times, and finally found that there was really nothing to talk about, so he returned with Cai Qu and Guo Zu and other scholars.

He wants to go back to Daqi, where he is about to report to him about the affairs of this time.

----------------------------

At this time, in the wine shop of Dongpingling, Xun Yu was lying in the opposite building with the Qingnu and a cadre of the county. Here, the situation of liquor stores is abundant.

In their sight, a short and fat man was shouting at the liquor store:

"It's still the same, give Naigong a bucket of corn, two catties of pork, and three taels of pulp, and hurry up."

After receiving the order, he hurriedly began to go to the back kitchen to order the rectification.

Seeing that this person was defenseless, Xun Yu asked the young slave in a low voice:

"This person is going to practice with Zhang Chong, are you mistaken?"

The young slave nodded with a huff:

"Hui Langjun, it's true, I've been staring at him for a long time, I won't be mistaken."

Why are the young slaves here?

It is said that since he abandoned Zhang Qiu and escaped alone, he has not dared to return to Dasangli. He knew that the most ruthless person in Da Sang was not Da Langjun Zhang Qiu, but the third elder Zhang Hong.

During this time, he had worked as a mountain liao, a domestic servant, and even a ranger in the neighborhood, but who would take a person who didn't know the roots?

Therefore, the young slaves have always been unwilling, crying hungry and cold, and have no fixed place to live. But that's it, he was still caught by Zhang Hong.

At that time, he was sleeping in a broken ancestral hall, and a sack was put on his head, and then he was brought to Zhang Hong. ….

Without waiting for Zhang Hong to say, the young slave told Zhang Hong all the scenes that happened that day, and when he said that Zhang Suo killed Zhang Qiu, Zhang Hong, who had been squinting, was silent, and he was older than before at this moment.

After the young slave finished speaking, he closed his eyes and waited for death.

He said that he did not expect to live, but that he wanted to suffer less sin. But the development of things exceeded Qingnu's expectations, Zhang Hong did not kill him, but said to Qingnu:

"Qingnu, now that you are no longer my house slave, you can change back to your original name Yin Li. You have been with me for so many years, and you have done your best in this matter, I will not kill you, but there is no more kindness between you and me. Later, I will recommend you to a nobleman, you follow him with your heart, and you will not go back to Da Sangli in the future."

When the young slave heard this, he was like being struck by lightning, and he was speechless for a while, so he could only kowtow to Zhang Hong's back with tears.

After that, Qingnu, oh no, it was Yin Li, who was recommended to Xun Yu by Zhang Hong, and specially followed Xun Yu to be responsible for the intelligence of the Taishan thief.

And the person in the wine shop that Yin Li is eyeing at this moment is his biggest achievement during this time.

Yin Li knew before that the gang of people who practiced with Zhang Chong were not dead. And he was also keenly aware that Zhang Chong's gang should have a close relationship with the Taishan thieves.

I didn't see it, the leader who was said to be the leader of the Taishan thieves, he waved a big banner with the word "Chong", and was also known as General Shi to the outside world. Although Yin Li still didn't believe that Zhang Chong would be this Shi Jiajun, with so much information, he had to take this possibility seriously.

And it was also the wealth that came down to him, and one day he wanted to recruit local rangers in the wine shop. They used to hang out in the liquor stores.

But that day, he bumped into a person, looked familiar, and then suddenly remembered that this person was not Zhang

Dog donkey?

I went to practice with Zhang Chong back then, but there was no news after that, and then the whole family followed Zhang Gouzi and their family to Shigu Mountain.

Why is he here?

There were already doubts in his heart, and Yin Li was even more concerned. After that, he kept an eye on this person, and found that this person would enter Dongping Ling City to eat meat every three or five days.

Yin Li was suspicious, where did this poor stick get the money?

After that, Yin Li reported the matter to Xun Yu, Xun Yu didn't say a word, took his father's talisman, and ordered a wave of county guards, and he was going to take down this person.

For Xun Yu, what is the benefit of thinking so much? Take it directly, under Miki, what is there not to say?

Since the defeat of the Dongping Ling soldiers, Jinan Xiangxun has been a little self-defeating.

The two Qingzhou junjies recruited by Xun Yu for him, after being entered by Xun Qi's bus, they all intersected with county affairs, and then put themselves in the cabinet and studied gracefully all day long.

Xun Yu, who hoped that his father would become a Chan, knew that his father's heart knot was this Taishan thief, so he volunteered to take over the job of Jinan to ask the thief to stab the girl, he wanted to see how the Taishan thief was, in order to cheer up his father, this thief had to be suppressed.

At this moment, on the wooden building opposite the wine shop, everyone watched the rough man eating and drinking there, and a few of them were aroused by gluttony, and their stomachs kept ringing.

Xun Yu has his own rules for doing things, he has already prepared food, and this will already be sent by the apprentice with a basket of boiled meat.

The county guards were so shocked that they exhaled quickly, but in the end, it was the elite selected by Xun Yu, and they knew the severity at the moment, so they all pressed it and waited for Xun Yu's orders.

Xun Yu untied the meat knife worn on his waist, took the lead in cutting off a piece of white meat, and put it in his mouth:

"Eat!"

The county guards were no longer polite, and began to whirl the clouds against this basket of meat.

Sure enough, it is Shaolangjun, and doing things is atmospheric.

Seeing everyone eating, Xun Yu instructed:

"Don't do it in the city for a while, there are many eyes and ears in the city, let's wait for him to get out of the city, capture him outside the city, remember, you must catch him alive."

All the soldiers, huh.

Please call me Mr. Chen
