Hua Houwei looked at Wang Zhi and pushed the ginseng soup on the table: "Drink some ginseng soup first." Haven't slept in three days, right? Wang Zhi! I'm telling you, it's a no-no! Master, I have something new in my hand, every project is like this, how many days can you survive? ”

Wang Zhi smiled nonchalantly, reached out and picked up the ginseng soup and drank it all: "Your Highness, Lao Wang, I am strong, this is nothing." ”

Hua Houwei smiled and patted Wang Zhi's shoulder: "Master, eat first." After dinner, I'll go with you to the war bureau. Well, let's talk about it on the road in a moment. ”

After Wang Zhi finished breakfast, the two left Kunning Palace and went straight to the military battle. "Master, did you get the seamless iron pipe out?" Hua Houwei is most concerned about this, which is related to the key to the manufacture of guns in the future.

"No, it's just that the furnace temperature is not enough, and the iron ore can't be turned into molten iron, so it's okay to do anything else."

"Well, that's easy. Ming and I will go to the Taoist temple and find something, maybe it will be solved. ”

"Why do you still need to find it in the Taoist temple? Your Highness, there are a lot of ores in our military battle bureau, and there are a lot of useful and useless piles, where do you still need to go to the Taoist temple? ”

Hua Houwei reacted now, this is not the era of the Qing Dynasty, the Ming Dynasty is not exclusive to science and technology, maybe there are really any ores, and it also saves himself a lot of effort. "That's a good feeling!"

As he spoke, he arrived at the War Bureau, where the foundry workshop was in full swing, and the ground was filled with hollow iron pipes with the thickness of gun barrels. It's a pity that each one was made by a craftsman who turned the iron bar circle and built it together.

The leader of the War Bureau, the eunuch Xu Deqiang, was very enthusiastic, holding the drawings drawn by Hua Houwei in his hand, and kept asking Hua Houwei: "Your Highness, your heating pipe is not a novelty, but this stove is a bit tricky." What is this? ”

Before Hua Houwei could answer, Wang Zhi frowned and reminded: "Xiao Xu, are you here to ask Your Highness?" ”

"Hmm! Blame me, blame me, look at my brain! Your Highness, please come here. ”

Xu Deqiang led the two into the hut next to him, and Hua Houwei asked with a smile: "Xu Banban, have you ever heard of coking coal?" ”

Xu Deqiang was stunned for a moment, and immediately shook his head: "No, what is this that His Highness said?" ”

Hua Houwei smiled, took out a pencil, and wrote on the hard paper on the table: "It's about the same as burning porcelain, oh, no, it's about burning charcoal." Put the coal in the kiln and burn it, and when it comes out, it becomes coking coal! ”

Xu Deqiang looked at the pencil in Hua Houwei's hand: "Your Highness, this is the pencil, right?" What a nice thing! Your Highness, what can this coking coal do? ”

"What? Hehe, don't you think iron mineralization can't become water? It can be solved with coking coal! ”

Xu Deqiang forgot about the pencil in an instant, and a fanatical light shot out of his eyes: "Your Highness! Is this true? ”

Hua Houwei smiled: "Lao Xu, I don't plan to do this myself, otherwise I would have said it to Shaoli every day." Try it and you'll know if it's true or not! As he spoke, he remembered that when he was working as a caster in a small private blast furnace, he was really exchanging his life for money!

Xu Deqiang stayed for a long time, and suddenly rushed out. Hua Houwei shouted: "What's the hurry? You take me to see the quenching process! ”

"Your Highness, do you know this?" Xu Deqiang was taken aback, this blacksmith's thing is not poetry and songs, and few people in the world understand it. No matter how talented His Highness is, it is impossible for him to learn such a thing.

Wang Zhi's face sank: "Xu Deqiang, you said too much!" That's what you can ask too? ”

Xu Deqiang was shocked into a cold sweat, and immediately knelt on the ground: "Your Highness..."

Hua Houwei smiled: "Eh! Don't do that! Wang Banban, he only has technology in his head, where does he want to be humble? Xu Deqiang, don't ask, I won't say, but you do it first, with the result, isn't it better than knowing how to raise chickens? ”

"Yes, yes, the little one is overjoyed. Let's take Your Highness down to see it! ”

The three of them left the hut and walked through the hot workshop into a tall room. "Your Highness, come and see!" Xu Deqiang pointed at the tinkling craftsman and shouted loudly.

Hua Houwei shook his head and sighed, didn't speak, and looked all the way. After watching the entire quenching room, Hua Houwei didn't say a word and went straight to the outside of the house.

"Your Highness, Your Highness, this quenching is nothing, right?"

"No, that's a lot of questions. Alas, I can't tell for a moment. You call someone who knows how to do it, and find a place to talk about it in detail. ”

Xu Deqiang immediately ran into the quenching room, and Wang asked Hua Houwei: "Your Highness, is it inappropriate?" ”

"The technique is too simple, and I can't do too delicate work. How? Do you know this quenching? ”

Wang Zhi smiled: "I know a little bit about it." Your Highness, I used to be a prisoner, and I was also concerned about the creation of weapons. ”

Xu Deqiang rushed over with a calloused craftsman: "Your Highness, this is Foreman Huang, and he has been striking iron for decades. ”

"Well, find a place, I'll tell you!"

Xu Deqiang led the way, and several people came to the hut next to them to rest. Hua Houwei didn't care about the dirty, he sat directly on the oily stool, took out a pencil, and began to draw on the paper on the table: "I don't know much, so I will remind you of two points." One is that the quenching tank should be large, and it should be cleaned and stirred frequently; The second is to quench with oil after heating, do not use water! You don't have to know the principle, just try twice! ”

Xu Deqiang didn't see the mystery in the picture, but the yellow foreman frowned, looked at the sky, and thought for a while. Suddenly, Foreman Huang shouted in surprise: "So that's the case!" I said that the ancient books said to use butter and mutton fat, but it turned out that this was missing! Your Highness, Lao Huang begs you to wait a little longer to see if Lao Huang is doing the right thing! ”

Hua Houwei smiled, walked over and helped Huang Foreman who bowed to the ground: "Go!" Let's go! ”

Back in the quenching room, Foreman Huang called a few craftsmen, and several people discussed for a while, and then scattered to prepare. Hua Houwei sat on a small stool and looked at it with a smile.

An hour later, Foreman Huang brought a large iron box that had just been made and poured large pieces of beef and sheep fat. A charcoal fire is lit under the tin box and the beef and sheep fat is slowly melted.

Hua Houwei couldn't sit still, stood up and walked to the box, and observed carefully: "Lao Huang, the oil temperature can't be low, otherwise the sword will be seriously deformed." ”

Huang Foreman used iron tongs to pinch out the red knife embryo and put it into the iron box. Laugh at! A puff of smoke rose, and Wang Zhi picked up Hua Houwei and ran out.

"It's okay, it's okay, that's it. Hurry back and I'm going to see the effect! ”

Foreman Huang looked at the knife embryo taken out of the iron box, suddenly grabbed the knife embryo, and slashed at a wire on the anvil! While! The knife embryo bounced up, and the yellow foreman looked at the intact knife embryo and cried bitterly!

All the craftsmen put down their work and gathered around, touching the glittering blue knife embryo in amazement.

"Crying for what? Hurry up and open the blade and bring it back to Your Highness! "Xu Deqiang is a eunuch in charge in the end, and his brain is flexible.

Foreman Huang shook his head: "Xu Tou, it's not that simple to open the blade!" ”
