After leaving the northern mining area, Luo Lan returned to the West Coast Special Zone non-stop.

Here he met dozens of charcoal merchants. These people, like the winemakers, used to provide charcoal for the nobles, but now they have lost their usefulness and have come to the Special Administrative Region to carry coal and build roads.

Rick gathered them together and waited for the prince to summon them.

Luo Lan didn't talk nonsense when he saw them, and said bluntly: "Do you know where Jig's group of winemakers went? ”

Everyone looked at each other, nervous and expectant: "I opened a workshop, and I heard that a kilogram of wine can be sold for a gold coin." ”

"That's right, you can be like them, but instead of selling charcoal, you can sell blackstone. We co-funded the creation of a Blackstone workshop. ”

"Selling Blackstone?"

More than a dozen people were all shocked, and they looked at each other for a while.

They have a lot of trust and respect for His Royal Highness, but selling black stones is too unreliable. Because blackstones are everywhere, and only His Royal Highness the Prince dares to use them, once they leave Phuket Island, who dares to use blackstones?

Luo Lan observed his words and knew that this group of businessmen had already vetoed his proposal.

He was not in a hurry, and while drinking wheat wine, he instructed Rick: "Rick, take them to see the smokeless black stone, and demonstrate it carefully, to see if charcoal or black stone is better." ”

Rick didn't say a word, and he wasn't too tired to go back and forth.

A dozen charcoal merchants immediately followed Rick to the northern mining area. Luo Lan waited for a while, but her mind became active.

He has always attached great importance to coal, but because the coal in the special industrial zone is very low-quality, he does not want to see it, so he has never tossed coal.

But now anthracite has been discovered, and this thing is an important mineral even in modern society.

Luo Lan recalled the use of anthracite coal for heating at home when she was a child, and the shape of anthracite with round holes came to mind.

That's the modern nest bee coal.

Completely different from the nest bee coal invented by Gulmis, the modern nest bee coal has undergone raw material processing, machine casting and other procedures, not only the shape is standardized, the small holes are neat, but also almost completely combusted.

But this world cannot process and cast anthracite.

Luo Lan herself didn't know how to do it. He gave up after thinking about it, manual punching is too unreliable, there is no need, and lumpy anthracite can also be used.

Luo Lan exhaled, secretly wanting to be content, lest the human heart be insufficient to swallow the elephant.

As a result, out of the corner of his eye, he saw that some workers on the road were driving to the coast with pieces of bee coal of various sizes in ox carts.

Luo Lan stood up in shock.

He thought he was wrong, but when he ran over and took a look, it was really a real nest of bee coal!

They are square or round, long or short, and strangely shaped, but the small holes on them are very standardized, as if poked out with chopsticks.

Luo Lan had seen Gulmis's bee coal, which was completely a small hole drilled by the method of "drilling wood for fire", and there were several small holes in a piece of such bee coal.

However, there are more than a dozen small holes in the nest bee coal in front of him, densely packed as if he doesn't need money, where can there be workers who have so patience and time to do this?

"How is this done?"

Luo Lan asked in surprise, he knew that this kind of nest bee coal was definitely not made by artificial drilling.

The workers pointed to the high mountain not far away: "Gulmis did it, he had to do it on the top of the mountain, and we went up and down the mountain to death." ”

The workers laughed and complained, and Luo Lan turned around and ran towards the high mountain.

The mountain has carved out a mountain road, which is not steep, and there are workers carrying the bee coal.

And under the abundant sunlight on the top of the mountain, dozens of girls are tinkering with something. Gulmith and some of the workers were also busy.

Luo Lan looked over, her eyes flashed, and she couldn't hide her amazement at all.

At the top of the highest mountain, a large flat field is drying bee coal. The nest coals were moist and fluffy, like freshly pinched ceramics, slowly drying out in the sun and wind.

On the other side, the girls stirred the charcoal in the barrel, adding some water from time to time to stir.

Ten meters away from the barrels, strong workers are smashing coal with hammers, smashing the hard coal into cinder crumbs.

This set of processes is very primitive, without the participation of any machines, but it is an eye-opener for Luo Lan.

The coal is smashed, then mixed with water to condense into soft coal, and then kneaded into a nest of bee coal, which is poked and dried with a wooden stick.

Solids to liquids and solids!

"Gulmis!"

Luo Lan shouted, everyone looked over, and then greeted him excitedly.

Gulmis, who was covered in slime, ran over and scratched his head honestly: "Your Highness, you are looking for me." ”

Luo Lan kicked him: "Why didn't you tell me about this thing?" ”

Gulmiston was frightened, and the people around him stopped laughing, thinking they couldn't do it.

"Your Highness, I just wanted to make it easier to punch holes...... After the rain that day, I saw that there was a pile of debris that melted together, and after a few days it turned into a stiff black stone, and it still burned, so I thought about it......"

Genius, absolute genius!

Gulmis was destined to go down in history, and Luo Lan hugged him and expressed his gratitude.

Gulmis was surprised and delighted: "Your Highness, you have already rewarded me last time, so this time I thought that there was no need to ask for credit, anyway, it was not a big deal and I didn't tell you." ”

"You didn't ask for credit, so I almost gave up the bee coal, this is a big crime!" Luo Lan reprimanded, and looked at everyone again, "Gulmis has improved the nest bee coal, and rewarded ten acres of land and one thousand gold. ”

Everyone screamed, and everyone drooled with envy. The news soon spread throughout the special industrial zone, once again igniting the enthusiasm of the people for invention.

And Luo Lan also suppressed his excitement, and he carefully observed the bee coal.

Since it is all made by workers, there are still some problems. For example, cinders cannot be refined, recasting is not sticky enough, and perforations are easy to spread.

But on the whole, it is still very advanced, and even Luo Lan was shocked, he felt that Gulmis's IQ was comparable to that of Einstein.

After the observation, Luo Lan also gave an opinion.

"In the future, you will standardize the manufacture of bee coal, and make it a round shape of the same size, about the size of two fists. In this way, the nest bee coal can be stacked on top of each other, and the firepower can be better than the other. ”

Luo Lan's words made Gulmis's eyes light up, and the workers also said yes.

Luo Lan said: "To create punching tools, we have blacksmiths and carpenters, and we can make a punching hammer with ten wooden sticks. ”

The top of the mountain was hot, and the workers talked a lot and found a new way out.

"Whoever can invent something good will get a knighthood and a reward, and everyone should move their heads more. Just like Gurmis, when he sees the black stone mud melted into a ball by the rain, he can think of adding water to stir the black stone crumbs! ”

"Good!"

The shouts shook the sky, and in the cold winter, the enthusiasm of the workers washed the north wind to pieces.
