Yuzhang looked at that handsome figure, his eyes were full of light, and he murmured to himself - no hunger, no war, no hatred, from now on, he will be rich and healthy, with descendants. Isn't that the era of great governance that the saint said? Isn't it?
Is this the target of my father’s pursuit?
"Yes, I didn't expect that I still underestimated him. Sister Huang, I must marry him. Only such people are heroes and worthy of being crazy for me, Jin Yang." The little girl Jin Yang also had light in her eyes.
"You've gone crazy." Yu Zhang said angrily.
"Aren't you?"
Yu Zhang was startled, but did not refute, with a sad look on his face.
Jin Yang stopped teasing and said seriously: "Sister Huang, are you worried about the Tang family? The Duke of Ju is a great man, but his son Tang Shanshi is a loser. His father actually wants to marry the emperor to this loser.
, Fortunately, it’s just that I’ve just made up my mind, and I haven’t made a decision yet. I’ll try to persuade you later.”
"No matter how I advise you, it's all up to your parents to decide on marriage matters."
"Don't worry, I have a way. Just remember our agreement. Although we are princesses, we are just caged birds. We have to get married after all, but marrying anyone is better than marrying that loser. Brother Qin's brother is both civil and military, and he is benevolent and righteous.
, ten thousand times better than him."
"Why are you so crazy?" Yu Zhang was speechless, but there was some inexplicable expectation in his heart. He couldn't help but look at the back of Qin Huaidao as he left, and his heartbeat began to accelerate.
…
Qin Huaidao didn't know what the two sisters were thinking, so he came to a hillside with his guards and gave an order. Twenty people went up to dig with tools. They first cleared away the weeds and then dug holes. The excavated soil was square.
It is good for leveling the ground and forming a flat surface for stacking coal.
It took three days to dig out a large kiln. The entrance of the kiln was reinforced with stones to prevent landslides. There was no problem with stacking a thousand bricks inside. The chimney was also reinforced just in case. Qin Huaidao checked it and made sure there was no problem.
With the latter order, more people followed the law and dug brick kilns.
Five days later, the coal was delivered. Qin Huaidao asked the guards of the house for help and found a place to dig a long pit. Women and children helped to move stones of various sizes from the river to reinforce them. He was very busy.
On the seventh day, more coal was delivered, and the kiln was still being dug. Qin Huaidao asked his guards to help pour some coal into the pit on the ground, light it, and burn it. After it was all burned, he covered it with earth and cut off the air. Can it be burned?
Chu Jiao Tan actually has no idea, he has to give it a try, and if it doesn’t work, just say so.
Early the next morning, Qin Huaidao hurried over to check, feeling uneasy. He saw that there was no smoke overflowing, and the temperature of the surface soil had also dropped. It was estimated that it was almost burned. He asked people to dig it up and take a look. They found that the pieces were of different sizes, ranging from silvery white to gray black.
Wait, it has a metallic luster. I picked up a piece and looked at it. It was a little hard and had holes. It was coke. I was immediately delighted.
Although it seems to be of average quality, it is coke after all and burns at a higher temperature than coal. It is much better than charcoal for smelting iron and stone to make weapons.
Brick kilns can be fired with coal. If you refine the coke yourself and bake it, the effect will definitely be better, even if the quality is lower. Qin Huaidao looked at the coke in his hand and his heart dropped.
"Young Master, how are you?" Jia Youcai came up with his guards and asked nervously.
"Just burn it like this. The brick kiln will burn as much as it needs. The excess black soil will be kept for future use. The burned soil will be piled up in another place and a shed will be built to protect it from the rain. Remember, this craft must be mastered by the family and is limited to you.
A few people know about it, but others are not allowed to have contact with it.”
Although Jia Youcai didn't know why Qin Huaidao valued this thing so much and didn't know what it was used for, he felt it was very magical and unusual. He solemnly said: "I'm sorry, the skills have been precious since ancient times. The young master passed it down to everyone, so everyone should cherish it even more."
, this matter is important, please be careful, otherwise don’t blame me for being rude."
"Please don't worry, young master, we will save it." Don't be careless, remember it quickly.
In the past few days, a lot of bricks have been made, and the sun has been shining for several days in a row. All of them have been dried, and they are waiting for the coke. Now that the coke is made, Qin Huaidao's confidence is greatly increased. With an order, the bricks are sent into the kiln.
Niu San'er and Xue Rengui, who have experience in brick kilns, both came to help and are now taking command.
The bricks were stacked layer by layer, leaving some gaps in the middle. After all the thousand bricks were stacked, dry wood was used to light the fire, and coke was piled on top. Everyone looked in through the small square hole at the kiln entrance, full of doubts. Brick kilns were familiar with this kind of thing.
But in everyone’s opinion, are those small stones inside okay? Shouldn’t they be burned with high-quality charcoal?
When the coke is ignited, it turns red and releases a terrifying high temperature. It does not burn out as quickly as charcoal. It is magical. Inexplicably, Qin Huaidao becomes more mysterious in everyone's mind. It is obviously poisonous black soil.
, being despised by others, is actually so useful?
Qin Huaidao was not sure whether bricks could be burned by doing this, but he did not show it to avoid worrying everyone, so he drove them away. After leaving Jia Youcai alone, he warned: "Fire-burning is a technical job, and someone you can trust must be responsible for it."
, once word spreads and everyone follows suit, we will lose a way to make money."
"Please rest assured, young master, I will keep an eye on you." Jia Youcai suddenly became nervous when he heard that he could make money.
The temperature of the kiln needs to be controlled, but there is no thermometer. No one can understand it just by talking. Qin Huaidao found a discarded hoe and threw it next to the fire, and warned: "Uncle Jia, you must remember that the hoe is placed in this position.
Just keep the fire burning. If it becomes red and soft and shows signs of melting, you must reduce the coke and lower the temperature. Once the hoe becomes dark, you must add coke and raise the temperature."
The internal temperature of the brick kiln is generally controlled between 600 and 900 degrees, which is just right when the hoe is heated red. If it exceeds 1,000 degrees, the iron will soften, and if it is below 600 degrees, the iron will darken. Although testing the temperature with iron is not accurate enough, it is at least not accurate.
There will be too many problems, the key is easy to understand and operate.
In those days when there were no thermometers, it would be much better to have a reference.
Jia Youcai realized that this detail was very important, so he quickly wrote it down and said solemnly: "This matter is left to a few old brothers in the house to keep an eye on in person. It does not require too many people to control it. Young Master, rest assured that it will be foolproof. However, use black
I have no experience in stone burning, how many days will it take to burn it?”
Qin Huaidao was also the first to bake. He was not sure. He only remembered that when he was a child, he saw that burning in the village usually lasted about ten days, and some burned for two or three days longer. There were thousands of bricks in the kiln. Two days longer might be better, so he warned: "Bake for twelve days."
, you can’t stop in the middle, you can arrange for people to take turns to guard it. Once the time is up, close the kiln for three days, wait for it to cool down, open it, and then continue to burn the next kiln. Find an open space to stack the burned products, and build a wooden shed to protect them from wind and rain. "
Jia Youcai nodded solemnly and remembered every word.
Qin Huaidao thought for a while and warned: "Uncle Jia, I will leave early tomorrow morning and leave this place to Uncle Jia. Brother Xue is talented and trustworthy. If you have anything, you can discuss it with him. If you encounter any trouble, you can go to Duke Lu and Duke Wei."
."
"I've remembered it."
If possible, Qin Huaidao wanted to stay and wait for the opening of the kiln before leaving, but Li Er couldn't give him such a long time, not to mention that people can't keep their promises. What you promised must be done. After explaining something to Jia Youcai, Qin Huaidao found him separately.
Xue Rengui, Mingyue and Huang Lao explained it carefully again.
Afterwards, Qin Huaidao walked towards the hill behind the ancestral hall.
