If not for the correct map in hand.

Even if Zhu Hengyu is given a billion trillion years, I am afraid he will not be able to reach the core area of ​​the underground world.

original……

In Zhu Hengyu's plan, it only takes half a year to cross this area.

Officially arrived at the core area of ​​the underground world.

But in fact, from the day of departure, until the official arrival in the core area of ​​the underground world.

Zhu Hengyu and the 30,000 Chuanshan miners spent three years and four months!

Especially the thousands of passages behind.

It takes a long time to dig each channel before the correct channel can be dug out from various locations.

most of the time……

They all have to go along the wrong path for thousands of miles.

Later, at a plain cave wall, began to excavate horizontally.

Digging all the way for hundreds of kilometers, only then found an underground passage.

This passage is the only correct passage to the underground world.

If it weren't for the 30,000 monks of the Chuanshan tribe who were professionally drilling holes with them.

Don't say three years...

Even thirty years, three hundred years, it may not be able to cross this area.

In addition...

Zhu Hengyu is not a brainless person.

After digging the correct passage, Zhu Hengyu would not turn around and leave stupidly.

Instead, 30,000 Chuanshan miners will be ordered to refill the dug channels.

Even in some bottom fault zones, some collapses and fractures were artificially created.

The real passage is completely blocked.

It can be said……

Before Zhu Hengyu passed, if the difficulty of finding the way on this road was ten.

Then after Zhu Hengyu passed, someone later wanted to find it all the way.

The difficulty of finding a way is tens of thousands!

Even if the other party has the correct map, it will never survive for thousands of years.

Finally, Zhu Hengyu led thirty thousand Chuanshan miners to the core area of ​​the underground world.

Within the core area of ​​the underground world, there is a vast underground world that spans three thousand kilometers.

In Zhu Hengyu's conjecture.

This area should be empty and deserted.

Therefore, he brought 30,000 Chuanshan miners to build an underground city from nothing!

However, when Zhu Hengyu led the 30,000 Chuanshan miners to the core area of ​​the underground world.

Everything in the goal made Zhu Hengyu stunned.

Looking around...

Right in the very center of this underground world.

It's at the intersection of 72 lines.

A magnificent giant city exuding fiery flames stands proudly there!

Although the space at the core of the underground world is 3,000 miles vertically and horizontally, this magnificent giant underground city alone is nine hundred miles vertically and horizontally.

The city is huge enough to hold hundreds of millions of people.

Facing such a magnificent giant city, Zhu Hengyu was completely speechless.

how is this possible?

At the core of this underground world, there is such a magnificent city.

Why, I have never heard anyone say it before.

Haven't seen any relevant records in any books?

the most important is……

At this moment, this super giant city should be unowned, right?

Once you have the Lord's words...

Zhu Hengyu's plan to completely dominate the entire underground world, I am afraid it will be completely defeated.

Booming...

Just when Zhu Hengyu was stunned and his tongue was in difficulty.

There was a violent roar.

A raging fire light rose into the sky from the depths of the giant city.

Huhuhu...

In the violent whistling sound, the blazing firelight straddled half of the city and fell in front of Zhu Hengyu.

Looking around...

It was a fiery red body, extremely huge, with a body length of hundreds of meters.

A raging flame is rising all over, Super Fire Dragon King!

To be precise, this is actually not the Fire Dragon King.

It is the common master of all the fire dragon kings-the purgatory dragon king!

Huh...

At close range, the Purgatory Dragon Emperor twitched his nose first and sniffed towards Zhu Hengyu.

next moment……

The Purgatory Dragon Emperor converged his wings instantly.

With a muffled sound, the Purgatory Dragon Emperor's five bodies threw himself to the ground, crawling in front of Zhu Hengyu.

At the same time, a voice of urn sound, extremely pious: "Little fire...respectfully welcome the master!"

small fire?

the host!

Looking at the face in front of him, even if it crawls on the ground, it looks like a huge red meat mountain.

Suddenly, Zhu Hengyu couldn't help being stunned.

what happened?

Who is this guy who calls himself Xiaohuo?

Why would you call him the master?

Looking at Zhu Hengyu who was confused.

The Purgatory Dragon Emperor obviously also knew what had happened.

With a sad sigh...

The Purgatory Dragon Sovereign said: "Before the collapse of the first battle, the master told the small fire to protect the underground city and wait for the master to return."

While speaking, the Purgatory Dragon Emperor paused slightly.

Then he continued: "Although, Xiao Huo doesn't know what happened outside."

I don't know what the owner has gone through.

Turned out to be so weak...

However, in any case, the master is the master.

The master's soul aura, soul fluctuations, and soul imprint are completely unchanged.

Between talking...

The Purgatory Dragon Emperor, eyes that were bigger than the washbasin suddenly burst into glittering tears.

Looking at the Purgatory Dragon Emperor speechlessly, Zhu Hengyu had already understood it.

Obviously, Zhu Hengyu in the ancient times was once the master here.

This underground city was built by him.

As for the purgatory dragon emperor who calls himself Little Huo, he should have been nothing more than a weak little fire dragon.

only……

After the collapse of the continent.

Xiao Huo should be quickly resurrected in the sea of ​​purgatory fire.

And has been practicing till today.

Until now, although he still claimed to be a small fire, in fact, he was already a generation of Purgatory Dragon King.

It can be seen from the coercion emanating from his body.

The strength of this guy is stronger than that of the Golden Eagle Demon Saint, and it is also many times stronger! It's not a class at all...

If you say that the Golden Eagle Demon Saint is just a beginner-level Demon Saint.

Then this Purgatory Dragon Emperor is definitely the pinnacle of Demon Saint!

The strength alone is nothing.

The key is……

In this underground world.

The Purgatory Dragon King is invincible!

Even if you kill him, it's useless.

Drawing on the fire of purgatory in the heart of the earth, the Purgatory Dragon Emperor can be resurrected instantly.

In other regions, it may not be easy to say.

But at the core of this underground world.

The Purgatory Dragon King is invincible...

The Purgatory Dragon Emperor at the core of Purgatory, even if it confronts the true heavenly saints, it will definitely not fall behind.

It can be said……

The Purgatory Dragon Emperor at the core of Purgatory is the true Lord! And it is by no means a false saint like the Golden Eagle Demon Saint.

The whole power of purgatory, he asks and asks.

Every blow of the Purgatory Dragon King is accompanied by the power of the entire Purgatory!

of course……

Once left the purgatory core.

Then, the strength of the so-called Purgatory Dragon Emperor instantly dropped several grades.

Without extracting energy from the seventy-two veins, the energy of the Purgatory Dragon King is not unlimited. Without the endless fire of purgatory, he cannot be reborn from the ashes at any time.
