Lear's interest grew, and he reached out to take the charred stone from the big devil's hand.

It's very heavy, like metal.

By extending your perception, you can clearly detect the rich energy contained within.

It's like the magic power has been compressed.

Magmatic Carboniferous
[Level]: 3 star

[Characteristics]: After burning, it can release extremely high temperatures and attract magic power from all around.

[Evaluation]: Excellent weapon forging fuel.

Although the attributes are simple, this is what he wants!
Lear was in great joy.

I couldn't wait to look to my side.

"Big Demon, go and capture all the big-mouthed scavengers!"

"Bubblemon is responsible for imprisonment, and at the same time uses bubbles to expand the hole."

After the order was given, the big demon took action immediately. The power in his body surged out and disappeared directly into the void.

In just three or two breaths, he returned with the big-mouthed scavenger in his hand.
The big-mouthed scavenger beast looks ferocious, but its level is not high. Facing a level 15 hero, it can't cause any trouble.

After being caught, these people were still confused and didn't seem to understand what was going on.

Before he could react, he was imprisoned by bubbles.

Thanks to the big demon's extremely high efficiency, it didn't take long before the bubble of the bubble beast was filled with big-mouthed scavenger beasts.

These creatures have big mouths and bodies that are highly similar to lizards. They stare with big eyes and look around, looking very stupid.

The gray dwarf was a little confused when he saw this and said in a low voice.

"My great lord, the Big Mouth Scavenger is not very intelligent. All it does is eat and poop. It's very annoying."

"If you need it, I can take you back to the Iron City and ask the city lord to find another batch for you."

"Oh? Big-mouthed scavengers are common?"

"It's not very common, but it's not rare. If you look carefully, you can find it."

Lear became interested.

"How far is the Iron Melting City from here?"

“It will take about three days of walking.”

"That city is the city of you gray dwarves?"

"Yes, sir! It's us, the Gray Dwarves!!"

"Smelting Iron City has a powerful crossbow corps, a fully armed heavy infantry corps, and also the famous wild boar cavalry."

"It's the most powerful force around here!"

"The elves of the Holy Song Clan are as weak as newborn cubs in front of our Ironforge City."

"Really? How many people are there in Ironforge?"

"More than 20! Our army exceeds 5. We can destroy most of the forces around here!"

"Who is the most powerful person in Molten Iron City? What level?"

"It's our city lord, level 19, just one step away from transcendence!"

"Level 19? No wonder. What is the specialty of Iron Smelting City?"

"The armor and weapons we produce are welcomed by all factions! If you need them, you can also buy them in Ironforge. The gray dwarves do not discriminate against surface people."

"Interesting. What does Furnace City lack?"

"Ironmel City lacks nothing! It only lacks good wine!"

As the gray dwarf spoke, a hint of pride appeared on his face.

"And the auction house in the Iron Melting City is well-known in the surrounding areas of the Dark Mountains!"

"A semi-artifact was once auctioned here!"

"In two months, on the last day of December, the annual dark auction will begin."

“I highly recommend you to go and see what’s inside. It’s definitely an eye-opener.”

Lear narrowed his eyes slightly.

Semi-artifact?
He turned and looked at the night elf beside him.

Ishani noticed his gaze and nodded immediately.

"Yes, sir, three years ago, a demigod-level weapon was publicly auctioned in Ironforge City."

"Finally, he was photographed by a level 19 Tauren chieftain. A big riot broke out over this."

"Their annual Dark Auction is very famous near the Dark Mountains, and a large number of high-level treasures appear every time."

Lear was greatly interested.

This underground world is really wild. I have never heard of any semi-artifact auction in Lolan City. Of course, this may be because my original body’s class was not high enough and I could not touch this kind of field.

After continuing to ask questions for a while, he roughly sketched out the picture of the Iron City in his mind.

A dungeon with a level 19 hero, a complete army, sufficient logistical support, and prosperous trade, and it enjoys good prestige in the area.

But unfortunately, the opponent's main business is also weapons, which conflicts with the City of Wei Lu.

Otherwise, it is not unacceptable for the business to enter the underground world.

If you have the chance, you can go explore the Iron City.

The underground world always has a unique attraction.

While they were talking, the big demon also completed his mission and captured all the big-mouthed scavengers.

All were imprisoned in bubbles.

In the future, these will be your own fertilizer production tools.

Lear smiled happily.

Although there is no fertilizer plant, the solution in the fantasy world is simpler.

After the big devil finished his work, Bubblemon started the next move.

He pursed his mouth and blew out bubbles which fell into the hole.

The bubbles were like the mouth of a giant beast, directly biting off a large piece of soil, then floating up, flying to the side and falling down.

The bubbles are operating intensively, like dozens of excavators working at high intensity.

In less than half an hour, the one-meter-wide passage was widened to a diameter of three meters, connecting diagonally to deep underground.

When Bubble Beast stopped what he was doing, Li suddenly became impatient.

With full of curiosity, I followed the passage and entered.

After passing through a cave more than 20 meters long, we came to an elliptical space more than two meters high.

The diameter is about fifty meters.

Everywhere you look, you see dense magma and coal.

You can intuitively feel its surging magic.

Real mine.

Lear's face grew into a wide smile.

Once you get the magma coal, nothing will be able to restrict the blacksmith shop.

It's time to work at full capacity!!
But after a moment, he calmed down again.

Mineral veins need to be mined.

Judging from what happened just now, it is not so easy to mine safely. It may be necessary to build a base in the underground world to provide sufficient security protection.

But in this case, it can only be postponed.

This underground passage is not short from the City of Weilu, so it is inevitably out of reach to establish a base here.

The current territory cannot support him to mobilize too much force to garrison here for a long time.

The army is too small, and it is difficult to resist attacks such as the Bat Tide, which is not very meaningful.

As he thought about it, his eyes regained their calmness.

The fuel stored in the territory will be enough for a while, and it won’t be too late to make arrangements when we return from Loran City at the end of the month.

After making a calm decision, Lear did not linger for long and turned to leave the underground space.

He looked at the cute little guys beside him.

"Cover up this hole and don't let outsiders find it."

The Bubble Monster was not vague either. It spit out bubbles again and filled them with soil, completely blocking the passage.

A lot of dead leaves were also put on it to cover it, and at the same time, the bubbles easily wiped out the traces around it.

In this way, as long as no one is idle and suddenly comes here to dig ten meters underground, the magma coal will not be exposed.

After doing all this, Lear was in a very good mood.

Order the troops to withdraw and prepare to return.

Although I am very curious about this mysterious land.

But now is not the time to explore.

While waiting for the army to return to the underground passage, Lear seemed to have thought of something and looked at the short and ugly gray dwarf who looked like a rogue and villain.

"Where is Dark Mountain?"

The gray dwarf was stunned for a moment and whispered.

"Dear Lord, we are now at the edge of the Dark Mountains."

"Do you know the Keld Ratman?"

This name made the gray dwarf look a little unhappy.

"Those filthy rats killed an old red dragon some time ago. They have been particularly rampant recently."

"There are countless underground passages in Dark Mountain, which are natural shelters for those rats."

"It occupies almost half of the Dark Mountains."

"Even if it's the Molten Iron City, we have to avoid its edge." "Once all those rats are out, it will be a disaster more ferocious than a tide of bats."

There was an unspeakable fear in his tone, obviously he had witnessed the horror of those Kelder ratmen.

"You asked about the rats. Could it be that their traces have appeared on the surface as well?"

Lear nodded slightly.

"My territory has killed thousands of Kelders before. They already know the passage to the surface."

The gray dwarf's expression suddenly became interesting.

"My Lord, you may not know that those rats are extremely vengeful and the surface of the earth is also extremely attractive to them."

"The Rat Queen must have set her sights on you."

Li Er looked at the guy with a little surprise.

This is a pretty good calculation.

Intelligence suggests that the ratmen have already turned their gaze towards the surface.

He had a hunch that it might not be long before he would see the rats reappear in the swamp.

But this time, it won't be as simple as before.

They were able to occupy half of a long mountain range in the underground world, and even after killing a dragon, the spoils had not been taken away by other races.

You can imagine how powerful the opponent is.

But he was not afraid at all, instead he was quite looking forward to it.

After the gray dwarf finished speaking, he did not see the expected solemn expression on Lear's face, but instead saw a light in his eyes.

It's like, I'm looking forward to that moment.

The corners of his mouth twitched.

Are all humans on the surface monsters?
The overwhelming tide of rats was a natural disaster that even the Iron City was unwilling to face.

Why are you still looking forward to it?
In the end, it can only be attributed to the fact that humans on the surface have never seen the horror of the rat swarm.

Lear naturally would not say anything extra to a prisoner.

After all the troops returned to the underground passage, they turned around and left.

At the same time, the gray dwarves were also brought along.

As a member of the Smelting Iron City, this guy still has some value.

It will be useful when you go to the underground world again in the future.

And the forging skills they possess are also quite peculiar.

It's interesting that weapons can lead people to evil.

When I get back, I can try to squeeze it out and see if the forging skills of the underground world can give the Frye people some inspiration.

The gray dwarf didn't dare to say a word and was locked in the bubble and took off.

But just as I was thinking about memorizing the route to the passage, I suddenly felt dizzy and fell into a deep sleep.

Lear was in a very good mood as he watched the army gradually move deeper into the passage.

The first exploration of the underground world was a complete success.

Not only the established targets - the big-mouthed scavenger beast and magma coal, have been found.

Moreover, during the Tide of Bats, the Grave Guardian harvested a large number of souls, and the attack power of the sickle soared.

And the level 14 Shadow of the Mist also took this opportunity to be directly upgraded to level 15.

At the same time, through the mouths of the gray dwarves, I gained a preliminary understanding of the underground world.

Next time you come, you can build a mining base. You can also visit the underground city of Smelting Iron City and take a look at the dark auction where semi-artifacts once appeared.

It took more than eight hours to pass through the 80-kilometer-long underground passage.

By the time we came out of the underground passage again, it was already early morning on the 18th.

The sun had just risen, a huge orange-red fireball hung on the edge of the wilderness, and the morning glow in the sky was particularly eye-catching.

The round dewdrops on the leaves of grass and trees reflect the crystal and are full of vitality.

The bee colony still guards its surroundings tightly, and no ignorant creature dares to provoke it.

Lear saw the sun and breathed a sigh of relief.

I don’t feel anything on normal days, but after going deep underground, I can intuitively feel the preciousness of sunlight.

Without stopping, he quickly returned to the territory with his army.

Once we entered the wilderness, our speed suddenly increased.

Although they were away for only one day, everyone was eager to go home.

The cavalry marched at high speed and covered a distance of hundreds of kilometers in less than four hours.

It was noon when we returned to the City of Wei Lu.

Lear handed the gray dwarf to the blacksmith shop and asked the Frye people to exchange forging techniques with him.

Brin happily led the gray dwarf away.

Although they have the inheritance from their ancestors, they are also very happy to learn new forging techniques.

A race that is complacent and self-contained is not worthy of being cursed by the God of Forging.

After finishing the arrangements here, Bain was called over.

Indicates the big-mouthed scavenger trapped inside the bubble.

"These are large-mouthed scavengers, and their excrement can be used as high-grade fertilizer."

"You can have someone test the specific effects."

"Also, keep them near the pig farm and try to use them to grow colorful moss."

Bane looked at those monsters with exaggerated bloody mouths and lizard-like bodies with great curiosity.

"The name Big Mouth Scavenger is really appropriate."

"I'll arrange it immediately."

Lear nodded and continued.

"Also, I found magma coal in the underground world that can be used as a fuel substitute for the blacksmith shop."

“Its quality is as high as 3 stars!”

"It's an excellent forging fuel."

"After a while, we will dig it up. The fuel problem of the blacksmith shop will be solved."

"Also, bring back all the cave dwellers who are still at the iron mine. Let them mine the magma coal. The mining of the original iron mine will be suspended."

"In the future, ordinary iron ore can be obtained directly from the Night Shadow Tribe and the Barbarian Territory."

"We have a shortage of manpower, so putting them where they matter will yield greater benefits"

Obtaining ore from the outside world will not affect the foundation of the City of Wisdom. As long as there are mineral veins, production can be resumed at any time.

Not afraid of any changes.

The swampman hero responded quickly.

Lear didn't say much and let the other person go.

Then he thought about it and decided to bring the big-mouthed scavenger to the pig farm himself.

He was very curious about these guys.

What kind of advanced fertilizer is it?
He called over two vine fairies and directly wove a pigsty to house these big-mouthed scavengers.

Then we saw that these underground creatures did not make any attempt to escape, but instead began to frantically eat the weeds on the surface.

In less than two hours, this area of ​​lush vegetation was eaten down to the surface, leaving only the ground exposed, and even the grass roots were not spared.

Seeing this, Lear thought of what the gray dwarf said: low IQ, only knows how to eat and poop.

The corners of his mouth twitched.

But it doesn’t matter. The function of this thing is excretion. Why does it need to be so smart?

Seeing that it didn't look full yet, he called nearby staff and asked them to harvest some colorful moss to feed it.

These big-mouthed scavengers seemed to have no idea what it felt like to be full, and they ate as much as possible.

Lear's eyelids twitched.

Even the three pigs next door are not so exaggerated.
In this way, they ate continuously from noon to evening, and finally Lear saw them poop.

Its excrement is granular like sheep dung, and one can sense that it contains a hint of magical power.

Several staff members collected a basket of feces and poured it into a nearby area where colorful moss was planted.

The colorful moss, which had become wilted after being harvested, suddenly bloomed with vitality.

It was as if the video was played at a multiple of magnification, extending in all directions at an extremely fast speed.

Just by splashing a fist-sized amount of feces, the colorful moss expanded to an area four or five meters wide, with a thick layer of moss growing 20 centimeters high. It looked quite exaggerated.

This is advanced fertilizer? !

Lear just felt that his eyes were opened.

This piece of colorful moss is enough to feed a pig.

That’s awesome.

With great excitement, I tried it several more times and found that they were almost the same, making the colorful moss grow exaggeratedly.

Good baby, good baby!!
He looked at the big-mouthed scavenger beast as if he was seeing mountains of gold.

Why worry about feed and food in the future? !
After some experiments, I still feel unsatisfied.

Someone picked up some and brought it back to the territory and sprinkled it on the roots of the pitcher plants.

Then I saw the pitcher plant begin to sway as if it had taken an aphrodisiac, and then grow taller little by little at a speed visible to the naked eye.

Lear was jealous.

What the hell is this high-grade fertilizer? It's simply a growth accelerator!

I thought the big-mouthed scavenger was just an ordinary harvest, but I didn't expect this to be a heavyweight treasure! (End of this chapter)
