Speaking of the history of the Darkhearth, Madolan sighed.

"The establishment of the Dark Furnace Fortress can be traced back to 20,000 years ago, after the Black Iron Emperor led the rebel army to end the dark rule of the Spirit Suckers, he brought the surviving people here and carved this majestic dwarven city in the hard underground rock. ”

The white dragon admires the ancient reliefs on the stone wall, which tell the story of a strong dwarf wearing a crown who leads his people to rebel against a soul-sucking monster with tentacles on his chin, and cleans up the underground monsters to create a new home in the underground world.

"So, why did the city decay?" Bai Long asked curiously, looking at the houses that had fallen into disrepair.

Madolan's eyes were complicated: "After the demon invasion of the world-destroying war, the foundation of the continent was destroyed, the continent sank, and the fractured strata gushed out hot magma, and the land rift connected the sea, lava and seawater, completely cutting off the road from the Darkforrd to other underground worlds, and a large number of clansmen chose to migrate, and the Darkforger gradually declined. ”

Bai Long's eyes lit up: "So, the Dark Furnace Castle was originally connected to other underground worlds?!"

"Of course, at its peak, the Dark Furnace Fortress was one of the eight main cities of the Gray Dwarves, and it had business dealings with almost all the underground cities. Madolan's chest straightened, and she was deflated.

"Unfortunately, that was before, and now all external access is broken. ”

Half an hour later, Madolan took the White Dragon Lord and finished visiting the Dark Furnace Castle.

"That's all for the inner city, master, do you want to see the outer city? ”

Inner City, Outer City?

Bai Long thought in his heart, and the place where he came in was the back door, and the Dark Furnace Fort was built in the rock mezzanine of two underground spaces!

Led by Madolan, the White Dragon Lord walked through the stone pillars of the houses to the exit of the gates of the Darkfort Fortress.

Bypassing the huge underground urn city, in front of the white dragon, there is a two-hundred-meter-long city gate passage, the width and height of the passage are about fifty meters, and at both ends of the checkered floor, there are huge dwarf stone carvings of the same height as the passage.

It's just that the passage has not been cleaned for a long time, full of dust, and piles of rubble are scattered.

"These are the most outstanding dwarven heroes of the Darkhearth's history, and this is Mogra Darkhammer, who is in ....... ”

Walking on the dilapidated road, Madolan pointed to the tall stone sculpture and introduced the legendary story of the stone statue owner to the White Dragon Lord, and his tone was full of longing and yearning.

In the dwarf's half-real, half-bragging, exaggerated tone, the White Dragon Lord walked through the passage and pushed open the two huge stone doors at the end of the passage.

As the dust accumulated on the door spilled over the years, the White Dragon Lord's vision gradually widened, and it looked at the scene outside the door in amazement, a dilapidated avenue large enough for six carriages to run side by side, from the feet of the white dragon, all the way to the gate of the outer city of the Dark Furnace Fortress, a full two thousand meters long.

Looking at the rows of houses on the side of the wide road, Bailong can imagine the Dark Furnace Fort 20,000 years ago, the shops on the side of the road are like a picture, and the pedestrians on the avenue rub shoulders with each other.

The white dragon grabbed the guide and flapped its wings and flew into the sky.

In the sky, the white dragon found that this underground space was much larger than the one that came in, and it couldn't see the end at a glance, it put away the surprise in its heart, looked back at the outer city of the Dark Furnace Castle below, and had a more intuitive understanding of the glorious civilization of the gray dwarves.

On the ground below, a 20-meter-high semicircular city wall protects the dwarven architectural city, which is connected to a stone wall at the end of the city, and the gate of the inner city of the Dark Fort is located in the center of the circle.

A wide straight avenue connects the inner and outer city gates, dividing the magnificent city into two perfect quarter circles.

In the sky, it was also the first time for Madolan to watch the glorious achievements of his ancestors from a bird's-eye perspective, and suddenly, he thought of a sharp blade hanging over the head of the Dark Furnace Fortress, maybe the mage Ta Long who could fly had a way, and immediately became excited.

"Master, please save the Dark Furnace!"

"Hmm, what's going on?" Amos asked suspiciously, feeling the dwarf in his claws, his body suddenly trembling with excitement.

After a moment, the dwarf suppressed his excitement.

"Directly in front of the city, there is a fissure in the stratum that connects to the sea, and the sea water spews out of the rift and pours into the underground world where we are, and it continues to expand. ”

"If this continues, in a few thousand years, the underground space where the Dark Furnace Castle is located will be flooded by the sea, and it is precisely for this reason that our people continue to leave the Dark Furnace Fortress. ”

Hearing that the consequences were so serious, the white dragon didn't say much, turned around and flew in the direction pointed out by the dwarf, and sure enough, not long after flying, the white dragon saw Bai Lian hanging down from the crack in the rock above his head.

After flying for a while, the sound of water went from being deafening at the beginning to deafening now.

The falling waters converge on the ground to form a huge lake.

Looking at the ocean below, the white dragon observed the terrain here, fortunately the ground here was the lower end of the slope, and there was an underground passage to divert the seawater, otherwise the Darkfurnace would have been flooded.

The white dragon looked up in distress, like the dome of the sprinkler head, how could these leaky holes be plugged.

After thinking for a while, the white dragon had an idea, and it flew into the sky, and the dragon's breath spewed out from its mouth, spraying on the leaky rift, and it didn't take long for the rocks at the crack, along with the seawater in the cracks, to be frozen by the dragon's breath.

The white dragon continued to work on the stone wall, first flexibly using fossils into mud, and turning mud into stone to seal the cracks, and then, enchanting a magic array to maintain low temperature on the stone wall, completely freezing and stabilizing the water in the rock.

With such a huge project, it took Bailong half a month to plug all the leaks.

During this time, the Grey Dwarves also gradually identified themselves with their new owners.

On the shores of the seawater lake, the gray dwarf prince and the white dragon lord stood together, looking at the seawater lake as the water level dropped extremely slowly.

"Did you find the passage through which the MONOCULUS Tyrant entered?"

"Not yet, the people are still searching, and I suspect that the guy came in from under the water. ”

Half a month ago, after the White Dragon Lord learned that the Demon-Eye Tyrant appeared out of thin air, he discussed the confirmation with Soreus, and finally came to the conclusion that the Demon-Eye Tyrant is very likely to come from other underground worlds.

So, the two immediately decided to launch the gray dwarves to search for the passage, but they have been busy until now, and they still found nothing.

"No matter how long it takes, you must find the passage and take it into your own hands. ”

"Yes, master!"

Three days later, the White Dragon returned to the White Keep, prostrate on the Crystal Throne when an ogre guard walked in.

"Master, the Oblivion Adventure Squad asks to meet the singing mermaid. ”
