Chapter 292
"Pale stone usually appears near water veins, such as lakes and oceans. If you look carefully, there are a lot of them."
Field suddenly realized: When I was in school, I only remembered its chemical properties, and I didn't know where it was distributed. After all, it was not used in the exam.
Yago didn't expect Field to react so strongly. In his opinion, this kind of alchemical material that is everywhere is not worth mentioning at all.
After all, there are all kinds of alchemical materials, such as the foot binding cloth of an old widow and the toenails of a giant. And a grayish-white stone has no style at all.
"Master, when you touch pale... uh, that is, the limestone you mentioned, be careful of your hands. Limestone will cause your hands to peel."
Hearing this, Field was more convinced that the person in front of him was not fooling him.
"You are right. Limestone is calcium hydroxide, which is corrosive to the skin."
Quickly assembling a mining team, Field lit a torch and immediately led the team to find limestone. Although the rain had just stopped and the road was slippery, Field couldn't wait to find the raw materials for lime.
Following the river that runs through Starry Night City, they walked downstream for more than two hours before they came to a plain shallow lowland. The only thing that caught people's attention was the traces of camping on the ground and the bodies of two mercenaries that had been gnawed into skeletons.
"I'm sure it's here. We chose to camp here."
Yago took the shovel from the carriage and shoveled away the sticky rotten secretions on the ground, revealing the jagged blue-white stones.
"Yes, that's it!"
Field stamped his feet excitedly and laughed: "Very good, Mr. Yago, I will reward you with a gold coin as a reward. In addition, you are hired as a scholar of the Night Lord, and you can choose a room on the second floor of the winery as a bedroom."
"Ah? Really, really?" Yago was stunned.
When he was in the Griffin Province, he lived in poverty and had to work to earn money to get food.
When he tried to join the Scholars Association, he took out his proudest research results, but was kicked out directly.
"Who would have thought that my research results didn't earn me a single copper coin, but in the northern province full of death, I could get a gold coin by picking up a piece of broken stone at random."
Yago was confused, and didn't know whether to cry or laugh. It just felt like a dream, and he was still very moved when he woke up.
"It just so happens that the limestone vein is very close to the territory, so there is no need to spend a lot of effort to occupy it."
With a long sigh of relief, the big stone in Field's heart fell to the ground. With cement, the defense power of the territory will increase rapidly.
"Everyone collect limestone until the carriage is full."
No accidents happened. After collecting limestone, everyone returned to the territory.
Field immediately asked people to dig a pit, and at the same time arranged slaves to break the limestone into small pieces and throw them into the fire to roast.
"Sir, is this the cement you want to make?" Tisifa approached Field with a curious look on his face and grabbed Field's arm. "I've heard you talk about it several times."
"Making cement requires a lot of conditions. You need to build a factory dedicated to firing cement and a complete industrial chain. Let me make slaked lime first. Slaked lime is also one of the materials for making cement."
"To produce cement, you need to mix limestone with clay and iron powder, calcine at 1400-1500 degrees to form a clinker, then mix it with gypsum, and finally grind it into powder particles for use."
Of course, iron powder, clay and the like are by-products of other factories, so it's not too laborious.
Although he didn't understand what Field was saying, Tisifa still listened patiently: "Field, you know a lot."
"You must know a lot." Field showed a disdainful expression, and his eyes looked around unconsciously.
"Well, stop torturing my rabbit."
Ticifa understood immediately and turned away with a red face: "I couldn't control my expression at that time.
After teasing Ticifa, the limestone in the fire was almost burned.
"Throw the burned stones into the water."
Yago watched from the side. He was curious why the baron burned these stones and then threw them into the water.
Heating and then cooling?
What's the meaning of this? Yago couldn't understand.
"Sizzle~"
As the bubbles rolled, the limestone melted into the water, the originally clear water became turbid, and the stone disappeared.
"My lord, do you know alchemy?" Yago was surprised, "Where did the stone go? This is the first time I have seen alchemy magic up close. It's amazing."
"You can also say it's alchemy, haha."
"This is slaked lime. Let the slaves continue to burn it and then mix it with sand. This thing is similar to rice paste and can be used to build houses. ”
Many places in the empire used natural adhesives, such asFor example, it is too wasteful to use glutinous rice and potato powder to build houses. The food in the Night Territory is not enough for people to eat, so it is impossible to use it to build houses.
Advanced places will use mortar and loess, and magic materials are the best, but unfortunately they are extremely expensive.
It is worth mentioning that the Purple Gold Empire once mined volcanic ash to make a natural version of cement, which is almost the same as modern cement, so a large number of magnificent buildings were built.
But as time passed, they did not understand the principle and eventually consumed the rare natural materials.
After Field finished explaining, he asked someone to record it.
"Transfer two stonemasons from the brick factory and assign thirty slaves to them. Make qualified slaked lime for me quickly, supply it to the two outposts first, and build a circle of brick walls quickly."
After that, Field returned to the rest area of the castle.
"The Baron is a wise man."
After Yago finished thinking about the slaked lime, he was surprised.
"Of course." The stonemason said as a matter of course.
The next day.
After finishing breakfast, Field went to the Interior Affairs Office of the Grand Winery as usual to clock in for work.
"My Lord, something regrettable has happened. There are a group of slaves in the territory, and evil spirits have entered their bodies." Kao looked nervous, "They are cursed by the devil. Damn it, we should burn those bastards to death, otherwise the goddess will punish them."
"Fuck, evil spirits have entered their bodies?"
Field almost jumped up in fright, thinking that the terrifying demon had come to the Night Territory.
Then he remembered that in this world, colds are called evil spirits entering the body. Field sat down slowly and calmed down: "You scared me early in the morning, it turned out to be a cold."
"Tell me the symptoms, I'll confirm it again." Field pushed his non-existent eyes, and his calm eyes gave Kao courage.
"It's just weakness in the limbs, and the face is as hot as a boiled egg."
"That's right, it's just a cold. If you're worried, let Pastor Lydia release the Holy Light for them. It should be this heavy rain that defeated the already fragile slaves."
