Troubled times: Start practicing spiritual practice by taking care of your sister-in-law

At present, more than half of the construction work of the cottage has been carried out, and the wall of the cottage is now being built.

In order to be sufficiently defensive, the wall must also have a foundation.

Of course, unlike modern reinforced concrete, the foundation here is made of wooden piles.

In order for the village to accommodate two to three thousand people, the walls must be long enough.

You also need to look for a suitable place. If the ground is too hard and there are rocks underground, it will definitely be inappropriate and the wooden stakes will not be able to be driven in.

After finally finding a suitable place, we still had to draw the baseline, cut down trees, cut stones, and dig the foundation.

The birds and beasts in the surrounding mountains and forests have long since fled.

When the workers dug the foundation, they dug out less than fifty centimeters before they dug out a layer of dirty black soil.

It may not be accurate to say that it was soil. Anyway, the workers didn't know what it was, so they continued to dig down, making everything dirty.

"Qiang!"

At this moment, a worker swung his hoe vigorously, possibly digging into rocks, and made a crisp sound.

The worker brought a pickaxe and prepared to dig out the stone.

As soon as the iron pickaxe went down, the stones on the ground immediately broke apart. The workers dug out with the hoe. A touch of golden color flashed to the workers.

The worker picked up the stone, carefully wiped the "black mud" on it, and then shouted with great excitement: "I dug gold, I dug gold."

As soon as the worker shouted, all the surrounding villagers gathered around him.

"It's gold, gold and yellow." Someone agreed, thinking it was gold.

"We've made it, we've made it, and we've found gold."

There was a commotion from the crowd.

Hu Qiang came over: "If you don't even work, why are you hanging around here?"

"Captain Hu, Old Man Liu has dug gold, look." Someone in the crowd said, and then took the "gold" from Old Man Liu's hand and handed it to Hu Qiang for inspection.

Hu Qiang had never actually seen gold, but he had never eaten pork and had seen pigs running away. The stone in front of him was indeed the same as the gold they said.

"You guys wait here, I'll show it to Master Chen Xian." Hu Qiang said.

…

"Gold discovered?"

Hearing Hu Qiang's words, Chen Mo was stunned, and then he became excited.

If gold is really discovered, it will definitely be more than one or two pieces. It may be a gold mine. Then you will really make a fortune, and you will be selling private salt.

But when Hu Qiang showed Chen Mo the "gold", Chen Mo could tell at a glance that it was no longer gold.

As a battlefield owner, he also knew some knowledge about minerals. If he guessed correctly, the stone in front of him should be pyrite.

After Chen Mo took it, he looked carefully and found that it was indeed Huang Tie.

The appearance color of yellow iron is similar to that of gold, which can easily deceive laymen, and its shape is more of a cube, such as the stone in front of you.

Secondly, pyrite is easily oxidized and darkened in the air. It will change color as long as it is burned with fire, but gold will not.

"This is not gold, it is pyrite, but the color is like gold. You can burn it with fire and it will change color."

Chen Mo felt that it was still necessary to explain. If the villagers misunderstood that gold had been found, it would cause a commotion.

In order to prove it to Hu Qiang, Chen Mo directly broke open the piece of yellow iron in his hand. The section was yellow-white and had a metallic luster.

"Look." Chen Mo said.

Seeing that it was really not gold, Hu Qiang could not hide his disappointment.

"By the way, where was this thing found? Take me to see it."

"It's right where the cottage is built."

…

When Hu Qiang and Chen Mo came to the mountain.

The place where the yellow iron was found has been dug up, and the construction team even fought over it.

"Bang, that's mine, don't grab it." A villager punched it.

"What's yours? I dug it up."

Until Chen Mo came in front of them, they were still fighting.

Hu Qiang stepped forward and pulled them apart, saying, "Why fight? Master Chen said this is not gold."

The crowd calmed down when they heard it wasn't gold, but someone still couldn't help asking: "What is this color if it's not gold?"

Chen Mo didn't answer for the time being, but looked at the dug coal, feeling excited again.

This is undoubtedly pyrite.

Because most pyrites are accompanied by coal mines.

He picked up a piece of pyrite and smashed it violently.

Yellow iron is hard, slightly brittle, and easily broken. The cross section is yellow-white or brown, and silver-white bright stars can be seen.

"This is pyrite, an ore. Look at the color when it is broken open. Is it gold? If you still don't believe it, you can burn it with fire to see. The so-called real gold is not afraid of fire. If it is real gold, it will not It will change color." Chen Mo said.

In the face of huge interests, some people still don't believe even Chen Mo's words.

I actually lit a fire and burned it. Sure enough, after a period of roasting, the pyrite changed color.

"It's really not gold." Seeing this, the villagers all looked disappointed.

When Chen Mo saw the burning yellow iron, he suddenly thought of something.

Sulfur can be extracted from yellow iron.

Now that coal is available, the steps are not difficult.

And if he remembered correctly, sulfur seemed to be extracted from coal.

If there is sulfur, a bold idea appeared in Chen Mo's mind.

That's right.

It's gunpowder.

Mononitrate, disulfide, and charcoal.

I believe anyone who has read books has heard this sentence.

The production of gunpowder is not difficult, even simple.

The ratio of nitrate, sulfur, and charcoal can be checked online. Chen Mo has already known about it, and even made it himself and succeeded.

I almost injured myself once, so I stopped doing it again.

If you add some sugar.

Tsk tsk tsk...

Chen Mo suddenly became extremely excited.

If gunpowder is really produced, he doesn't know whether it will be easy to deal with those high-grade or middle-grade warriors, but it will definitely be no problem to deal with low-grade third-grade warriors like him.

If it is mass production.

That scene...

This emperor, can you, the Chu family, sit down, but I can’t?

Well, the emperor of the Song Dynasty was named Chu.

"Hu Qiang, stop the work at the village for a while, dig out all the coal and pyrite here, and transport them back to the village." Chen Mo said.

"Coal?" Hu Qiang was stunned.

"It's just this black dirt on the ground."

"promise."

"By the way, those involved in mining coal and pyrite are also responsible for three meals a day."

"Thank you, Immortal Master Chen."

…

After returning from the mountain, Chen Mo led people to dig out soil non-stop and built a furnace. The middle of the furnace was raised to reveal a round hole.

Chen Mo also asked Liu Gui to make a bowl with a bulge in the middle.

In this way, when burning sulfur, cover the bowl on the furnace hole, and the yellow vapor of sulfur in the pyrite will rise along the furnace hole, and will not escape when it is blocked by the bowl, and finally along the edge of the bowl body It enters the cooling pipe and flows into a small pool, where it condenses and turns into solid sulfur.
