Swamp Lord: I have an intelligence system.

After reading the information, Lear couldn't calm down for a long time.

Then he made a quick decision and headed underground tomorrow.

Although there are still 10 days until the Iron City Auction, there is still a lot to do this time.

These 10 days may not be enough.

The next morning, Lear got up, washed up simply, and immediately called the army together.

Just bring two battalions of Cold-Blooded Cavalry and Night Hunters.

Because the situation changed too quickly, Lear summoned out the Mist Shadow who was originally planning to stay in the Undead Plane to develop.

This special level 17 unit has a strategic role and he uses it very easily.

As for the Flesh Slayer, he was not worried and would just let it develop in the undead plane.

As he gained a deeper control over the power of authority, the power he had left in the Flesh Slayer began to shine like stars in his eyes.

As long as he wants, he can immediately summon this 18th-level divine life from the undead plane as a helper.

However, if the distance is too far, this operation may directly cause severe damage to the soul, or even death.

This limitation is also the reason why Lear only anchors the Flesh Slayer. The opponent can be resurrected, but ordinary heroes do not have this ability.

When you need to use the other party, just take action.

In addition, he also brought with him 7 great demons that were promoted to level 16, a level 17 two-headed ogre chieftain, and a level 16 mechanical dragon.

In this way, all the formations from the last expedition have been gathered together.

But after a little thought, Lear decided to bring the Scarlet Bee Queen and 15 squadrons of rhino warriors.

At the same time, there are 500 cavemen and 30 bubble beasts.

The territory is expanding rapidly, the blacksmith shop is operating at high intensity every day, and the originally stored fuel has run out.

The magma coal at the exit of the underground passage is a 3-star fuel, which is no less valuable than gold.

There was no time before, and if we don’t mine now, there will be no chance when the underground world collapses.

Under Lear's will, the army gathered quickly and various military supplies were moved out of the warehouse.

After everything was ready, Lear did not hesitate and led his army out of the swamp.

The City of Wittenberg has 5 squadrons of cold-blooded cavalry, 3 squadrons of night elves, 15 squadrons of dark nagas, plus a level Naga King and the Goblin God garrisoning there.

Additionally, seven squadrons of Ancient Treeman Guardians are taking root on the city walls.

There are also grave guards who can return from the undead plane to provide support at any time.

At worst, we can pull out six battalions of two-headed ogres who are working hard in the territory to serve as warriors.

The superficial strength alone is enough to resist most enemy invasions.

Not to mention the hidden power - in the vine-covered Wei Lu City, the vine fairy who has been promoted to 4 stars is the most terrifying fighting force.

They can directly control and connect the entire city. This power is not even inferior to that of a level 19 life form.

Those little guys the size of a fist are the big bosses hidden in the City of Wei Lu.

But that's not all. Lear left a unique power for Bane. If he encounters an unbeatable situation, Bane can sense it directly after activating it.

At that time, he will mobilize the power of the swamp, tear open the space, and return to the swamp.

This is the biggest killer.

As long as he is in the swamp, everyone who comes is a lamb to be slaughtered.

How can mortals understand the ways of gods?

Because of the presence of rhinoceros people, the marching speed was not fast, but the soldiers had strong endurance and they remained calm after marching for four or five hours at a high intensity.

By noon, the army arrived at the underground passage.

Looking over, at the entrance, vines have woven into a small fortress.

This was built by the Vine Fairy after Li'er defeated the coalition forces of the Anthem Clan last time.

Just in time to use it now.

While Lear was thinking, he waved his hand to let the swarm of bees guard the entrance to prevent any accidents from happening and cutting off someone's retreat.

The swarm of bees formed a terrifying tide in black mass, which was enough to make one's scalp tingle just by seeing it from a distance.

Even the most blind creature would not encounter this bad luck.

After making all the arrangements, he led the army into the underground passage.

Having had this experience before, Lear was much calmer this time.

Send 7 big demons to explore the way and eliminate the threats ahead.

This underground passage extends downward for hundreds of miles, is winding and rugged, and is not very safe.

But in front of the ferocious big devil, the monsters in the passage were no different from weak lambs.

Hundreds of monsters were killed directly.

It did not stop the army.

On the night of the 20th, the army finally emerged from the underground passage for the second time.

Last time, Lear encountered a bat frenzy at the exit, the terrifying number of which was still fresh in his memory.

Stepping into the underground world again, it feels completely different.

This time the army at hand is more ferocious, and the combat effectiveness of high-level heroes is incomparable.

At the same time, his control over power also made him more calm.

No matter what enemy you encounter, you can treat it calmly.

This high-level map can no longer move him.

Seeing the dim environment underground again, Lear took a deep breath.

He subconsciously looked up and when he saw the scenery in front of him clearly, his brows suddenly frowned.

Two to three thousand meters above the ground, it emits a faint glow and supports the sky dome rock wall of the underground world.

At this moment, exaggerated cracks appeared.

From time to time, you can see large pieces of rubble falling out of the cracks, falling straight to the ground and smashing into the vegetation below.

At the same time, at the end of the sight, several underground mountains that connected to the sky and the ground also had large cracks.

It seemed like it was about to collapse.

It gives people invisible pressure.

No wonder underground life is so crazy. The collapse of the underground world has been completely exposed on the surface.

Even if ordinary people don't know the will of the gods, they will feel uneasy when seeing this scene.

I’m afraid the current commotion is still small.

As the cracks widen, those underground lives that still hold a glimmer of hope will fall into complete despair.

Then, the wilderness will be the most chaotic.

Lear took a deep breath, calmed himself down, and immediately came to the place where he had discovered the magma coal last time.

Previously, Bubblemon had covered this area with mud. Now, although there are many footprints on it, the mud is still intact.

He waved his hand and asked the cavemen to open it.

These natural cave creatures have been armed by the blacksmith shop and are all equipped with professional digging and mining equipment.

The efficiency has more than doubled compared to before when I had to dig with my bare hands.

Each one of them was like a dog digging a hole, very quickly, and soon a big hole was dug out on the surface.

After a brief exploration, the 500 cave dwellers divided their companions into five teams of people and began digging separately.

Lear did not get involved, leaving professional matters to professionals.

These cave creatures immediately got to work in full swing.

The dirt and rocks on the ground were cleared away at an exaggerated speed.

It didn't take long before they dug up magma coal.

Lear felt even more refreshed as he watched large tracts of magma coal being mined.

This is a 3-star level fuel that contains tremendous energy.

After being ignited, it can also attract magic power to intensify the fire, which is a real strategic material.

At this stage, it makes people happy to be able to obtain such a mineral vein.

Living underground for a long time has allowed cave dwellers to develop their own mining system. The whole process was smooth and Lear felt it was very pleasing to the eye.

However, they soon discovered the problem. What they mined had to be transported up the site, which consumed a large part of their energy and prevented them from operating at full speed.

While thinking, he directly ordered Bubblemon to use bubbles to collect the mined magma coal.

When a certain amount is filled, it will rise up and gather together for later processing.

As a result, mining efficiency will increase significantly.

Li Er's mood improved as he watched the 3-star fuel come into his account.

They were not in a hurry to set off for the Iron Smelting City. After sending out Night Hunters to guard the surroundings, they also let the Rhino People and Cold-Blooded Cavalry participate in the mining.

The army's mining skills are naturally not as professional as the cavemen's, but they are of a higher level and have enough strength. They can use their own characteristics to make up for the shortcomings of their technology.

No one complained, and thousands of people began to dig the ground frantically.

The scene looks very hot.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

Soon, the magma and coal on the ground accumulated into a small hill.

Seeing this, Li Er immediately ordered Bubble Beast to load it with bubbles and transport it back to the territory.

In order to speed up the process, let the big demon escort them directly.

In this way, the 200-kilometer journey can be completed in two hours, and the round trip takes only four hours.

When he came back for the second time, the number of Bubble Beasts had increased directly to 60, and all the little ones that had been hatched before were also brought over.

In this way, 30 bubble beasts can be left for mining each time, and the other 30 can go back to deliver the goods.

With such high-intensity mining, the efficiency is amazing.

But even so, it took three full days to dig, and it was not until the evening of the 3rd that the mining was completed.

Thousands of people, together with the cooperation of Bubble Beast, worked day and night to dig large pits in the ground.

The deepest point reaches 50 meters!
After a rough final count, it was found that Bubble Beast had carried back a total of 6 bubbles full of magma and carboniferous substances.

The diameter of each bubble can be up to 4 meters.

It's full of magma and coal.

This data is quite exaggerated.

According to the blacksmith shop's estimate, even if high-strength armor is cast, this batch of fuel can last for two to three years!
This made Lear quite happy.

Great chaos is about to come. The richer the territory's material reserves, the more confident we will be.

The underground world is just beginning now, the real collapse has not yet come.

The situation will not be peaceful after the collapse, but will become more turbulent instead. The one who caused all this to happen is a divine evil that even the God of Creation cannot kill!
No one dares to predict what kind of turmoil would be caused if such a terrifying existence escaped the seal.

After taking possession of this long-discovered mineral vein, Lear did not waste any time and asked the rhinoceros people to escort part of the army back to the territory.

He planned to travel light this time.

The Ironforge City we are heading to this time is the city of the gray dwarves. These evil races are not friendly to life on the surface.

Bringing too many troops would be detrimental to mobility.

After thinking about it, he decided to only bring a few high-level heroes this time.

The big demon, the mechanical dragon, and the two-headed ogre chief.

However, just in case, the Shadow of Mist still collected 1000 cold-blooded cavalrymen and 1000 night hunters into its shadow cage.

After the upgrade, the shadow cage of this ferocious life can now imprison as many people as three battalions.

Enough to accommodate these troops.

The strategic significance of Shadow of Mist is highlighted here.

The first time the army came to the underworld, it captured a gray dwarf nearby.

At that time, Lear brought him back to the City of Dew, and now he is still helping him in the blacksmith shop.

That guy spilled all the information about the underworld.

From the information he provided, the City Hall drew up a rough map that roughly determined the direction of the Iron City.

That's enough to get the direction.

After the rhino leader returned with his army, Lear did not hesitate and flew directly into the air.

Go straight deep underground.

Seven huge demons followed them, flapping their wings.

The two-headed ogre chief and the mechanical flying dragon were also put into the shadow cage by Lear because of their huge size and majestic power.

In this way, their presence was greatly reduced.

To be safe, he concealed his breath, and the Shadow of Mist emitted a faint black mist, covering most of his figure.

Outsiders can only see blurry faces and cannot see clearly.

It takes about three days to walk from the exit of the underground passage to the Iron City.

The actual distance is about 200 kilometers, neither far nor near.

Lear flew directly across the sky, heading towards his goal.

The Dark Auction is still a week away, but by arriving a few days early, we can gather more intelligence.

The details of the Dark Auction are of paramount importance, especially the main target this time - the lizard demigod's eye that can upgrade the cold-blooded cavalry to a 4-star unit.

Flying in the dim and hazy underground world, the scenery on the surface quickly passes by.

In the dimly lit environment, the vegetation grows in strange and twisted shapes.

There is absolutely no vitality of the plants on the surface that grow towards the sun. Instead, there is a dark wind that makes people feel frightened.

Most of the branches and leaves are deformed and irregular, like dry palms that are wanton and unruly.

The colors are all grayish brown, tan, or even black, and they look gray without any bright colors.

There is an inexplicable feeling of depression in my heart.

If you survive in this kind of environment for a long time, even if there are no enemies, you will probably become psychologically distorted.

When flying across the sky, one can occasionally sense the presence of life among the vegetation on the ground.

Some are intelligent races, such as cryptmen, deep gnomes, and dark goblins.
But there are more ferocious beasts.

The giant rats with fangs, the tigers covered with thorns and barbs, and the venomous snakes with seven or eight heads were weird and twisted, without any of the beauty that normal creatures should have.

On the way, Lear asked the big devil to capture a few underground dwarves and ask them about the direction of the Iron City.

The dwarves had no idea of ​​other information, and they didn't even know where to run if the sky collapsed.

Lear could only shake his head and didn't waste time on it.

Speed ​​up your progress.

The closer you get to the Molten Iron City, the more creatures there are around you, and their levels are relatively high.

We even saw a few underground tribes along the way, but most of them were deserted.

It can be clearly felt that everyone is heading towards the Smelting Iron City.

Finally, after flying for more than two hours, Lear's eyes lit up.

At the end of the sight ahead, there appeared an extremely magnificent underground city.

It was carved out of the mountain and is huge and majestic.

The top of the city leads directly to the sky-high rock wall that supports the entire underground world.

Outside, the hundred-meter-high city wall stretches across the land like a chasm in the sky.

A series of ferocious and distinctive heavy city defense weapons stand on the city walls.

Even the high mountains at the rear that connected to the sky were filled with weapons for defending the city.

At first glance, it looks like a super giant hedgehog.

Anyone who attacks will have his teeth broken.

On the outskirts of the city, you can see ant-like black dots gathering towards the city.

It looks prosperous and lively.

Is this the Molten Iron City?

Lear immediately became alert. (End of this chapter)
