"This is charcoal essence!"

Old Duke held a ball of black coal balls in his hand and looked at Yang Dashuan.

After returning from the Hanging Swamp this time, Iverson not only brought about a hundred followers of swamp giants, but also filled at least nearly 100 tons of coal in the space ring that Yang Dashuan gave to Leren.[]

Yang Dashuan was interested in this thing because coal was easy to burn and could be specially supplied to military factories and blacksmith shops, avoiding the process of slaves having to burn down trees into coke. However, because the newly built laboratories also require a lot of fuel, Yang Dashuan allocated all these coal mines to Old Duke.

It’s a little bit to save, so Yang Dashuan thought at the beginning.

However, the coals were allocated to the laboratory, and the next day, Old Duke sent someone to call Yang Dashuan in a hurry. He held a piece of coal mine that was not much larger than his fist.

"Carbon Essence?" Yang Dashuan blinked his eyes, but he didn't react for a long time. In his eyes, this coal ball was no different from other things lying in the coal pile. "What is carbon Essence?"

"This thing is a long story. Let me tell you about the formation of ore veins first!" Old Duke held the coal balls and carefully placed the so-called charcoal essence on the table.

"The formation of every ore vein is a gift from the gods! In order not to allow people to get it for nothing, many ore veins will be buried deep underground. The formation of an ore vein must first have the appearance of crystal nuclei!"

"Crystal core?" Yang Dashuan interrupted Old Duke's words.

"Yes, it's like the crystal nucleus in the brain of the monster. The ore veins also have their own crystal nucleus!" Old Duke said word by word. "It is precisely because of these crystal nuclei that the mineral veins will spread outward. The longer the crystal nucleus is produced, the larger the mineral vein! Therefore, the crystal nucleus is often the most precious treasure in the entire mineral vein. The reason why the formation of the mineral vein is a gift from the gods is that few people can find the crystal nucleus of the mineral vein!"

This made Yang Dashuan roll his eyelids, and this thing was nothing like what he knew.

"Some people also proposed to purify the entire ore vein, which might be able to create objects similar to the crystal nucleus, but this is just empty talk." Old Duke pursed his mouth. "This is impossible! But some ore veins can do it, but this probability is very small... and it only exists in theory!"

This sentence made Yang Dashuan's heart thrill.

This old man has never been able to talk nonsense, but today he talked about such a big mess, which inevitably made Yang Dashuan feel a little anxious. In a vague way, Old Yang had already guessed what Old Duke wanted to express. "Are you saying that?"

"Yes, I have tried these coal mines and can be refined, and this thing is charcoal essence. Only every thousand pounds can be extracted with one pound of charcoal essence! Do you know? This is the gift of the gods!" Old Duke looked excited.

When did the coal mine become a gift from the gods?

When the coal mine is unwell, the forest is buried underground, which is only formed over a hundred million years? Is this old man mentally retarded? Yang Dashuan muttered in a low voice. He knew this since he was still wearing open-crotch pants. Now Old Duke has to relate the formation of the coal mine to the gods, which makes Yang Dashuan really unacceptable!

"Stop talking nonsense!" Hearing Yang Dashuan's muttering, Old Duke blew his beard and glared. "Tell you, two hundred years ago, someone in our alliance proposed what you just thought. But unfortunately, the church hanged this guy who proposed the "heretic idea" in public! It is a gift from the gods that can purify a thousand pounds of coal into charcoal essence in itself!"

"You're just nonsense!" Yang Dashuan pulled his collar and became popular on the spot. "Is the refined iron not purified from the iron ore? Is the refined gold not purified from the gold ore?"

As soon as he said this, Old Duke looked at Yang Dashuan as if he didn't know him anymore. He looked at him for a long time. It was not until Yang Dashuan was embarrassed to look at him, and then he burst into laughter.

Yang Dashuan thought the old man had nothing to say, and looked proud.

"Who told you that after iron is purified, it is refined iron? After iron is purified, it is obviously steel! Essential iron and iron are not a substance at all, and pure gold is not refined by gold. These things are completely invincible!"

Yang Dashuan opened his mouth and didn't say anything for a long time. Now he was so embarrassed.

However, these things don’t matter to Old Duke. What he cared more about was the charcoal essence. After Old Duke said this, Yang Dashuan realized that Old Duke’s so-called charcoal essence was not as simple as he imagined.

"Then this charcoal essence..." Yang Dashuan asked carefully.

"This thing is extracted from a thousand pounds, which means that the coal mines you brought back can't extract a hundred charcoal essence even if you die. Do you understand what I mean?" Old Duke looked at Yang Dashuan and said with a serious look on his face.

"No, I mean, what is the use of this charcoal essence?" Yang Dashuan asked anxiously.

The demand for coal mines in the territory is huge. Not only blacksmith shops, military factories, but also old Duke's laboratory requires a large amount of coal mines. Every day, slaves have to cut off wood and burn it into coal to supply the territory. Coal discovery in the suspended swamp is great news for Yang Dashuan. In this way, the fuel problem of the entire territory will be solved. Moreover, it can also provide fuel for future miracle buildings.

"The effect of this pound of charcoal spirit is equivalent to 1,500 pounds of coal. If it is released at once, it can create a power equivalent to intermediate group attack magic! This thing can be much simpler and more convenient to use than magic bone powder. As long as you smash it like this, it will explode!" Old Duke kept swaying the charcoal spirit in his hand from time to time, which made Yang Dashuan's eyebrows jump wildly.

But when it comes to the back, Yang Dashuan also became very angry.

It is only a stopgap to use the bones of the monster to create a "magic bomb" after all, and it is time-consuming and laborious to grind the magic bone powder. Without the help of the ancient snow beast, it would take at least a whole month to make Yang Dashuan rely on the power of the territory to create a "magic bomb" alone.

However, since the charcoal essence can also play the same role as the "magic bomb", Yang Dashuan was very happy. In this way, the two ends will start construction, and then there will not only be "magic bombs" in the territory, but also the charcoal essence.

It's considered double insurance!

"The waste residue after refining the carbon essence can also be used as fuel, but the effect is a little worse. It will be the same if you use more waste residue at that time! In this way, these coals can be used twice." Old Duke smiled and pounded Yang Dashuan who was immersed in joy.

"Then can this thing be used as fuel?" Yang Dashuan asked.

Since the carbon essence can be extracted, then the miracle building will naturally require higher fuel to fly in the future. Moreover, the carbon essence is smaller and is more conducive to carrying, and it can also reduce the load on the miracle building that flies into the sky.

"But it is simple to let the charcoal essence release all the energy at once, but if it is slightly relieved like burning, there are some problems. We have not mastered this technology yet! So now we can only use it as a 'magic bomb'!" Old Duke shook his head helplessly, and to tell the truth.

Although this is not good news, the emergence of "charcoal essence" is already beyond his imagination for Yang Dashuan.

With the "Carbon Spirit", the territory will have more destructive weapons and will be more deterrent to the outside world. After more guarantees, Yang Dashuan felt more at ease. However, these "Carbon Spirits" made Yang Dashuan know too late. If they had a little earlier, there might be no troops outside the territory. Although it was a little late, it would not be in the way.

"By the way, how is the yield of this charcoal essence?" After this excitement, Yang Dashuan couldn't help but consider other issues.

"With sufficient materials, at least four charcoal essences can be purified in a day!" Old Duke smiled. "This is twice the output of our original 'magic bomb', and it's not a big deal! If you add a little more manpower, the amount will be at least doubled."

This is quite a lot!

Yang Dashuan was happy on the spot.

However, before she had been happy for a long time, Yang Dashuan began to worry again. The distance between the hanging swamp and here is not close. It would take at least half a month to walk. Of course, this is still based on the itinerary of the swamp giant. If coal is mined like this, then it will take more time to go back and forth.

What should I do if I transport it then? This is also a problem.
