Speaking of the history of Dark Burrow, Madoran sighed.

"The establishment of the Dark 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 monster-sucking monsters, he brought his surviving tribesmen to come here and dug this majestic dwarf city in the hard underground rocks."

The white dragon admires the ancient reliefs on the stone wall, which tells the story of a strong dwarf wearing a crown, leading his tribe to resist the monsters that are tentacles, and clearing out the underground monsters to open up a new home in the underground world.

"So, why has this city declined?" Bai Long asked curiously at the disrepaired house.

Madoran's eyes were complicated: "After the demon invasion of the world-destruction war, the foundation of the mainland was destroyed, the continent sank, and the broken strata surged out of hot magma. The land cracked strata connected the sea, lava and seawater, and the road leading the Dark Fort to other underground worlds was completely cut off. A large number of tribesmen chose to migrate, and the Dark Fort gradually declined."

Bailong's eyes lit up: "So, the Dark Fort originally connected to other underground worlds?"

"Of course, the Dark Fort at its peak was one of the eight main cities of the Grey Dwarf, and it had business dealings with almost all underground cities." Madoran thrust his chest and then was deflated.

"It's a pity that was the past, and now all external channels are broken."

Half an hour later, Madoran took the White Dragon Lord to visit the Dark Furnace Castle.

"That's all about the inner city. Master, do you want to go and see the outer city?"

Inner city? Outer city?

Bailong thought in his heart that 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!

Under the leadership of Madoran, the White Dragon Lord walked through the stone pillars of the house and came to the exit of the Dark Fort City Gate.

Bypassing the huge underground urn, the city gate passage that is placed in front of Bailong is a 200-meter-long city gate passage. The width and height of the passage are about fifty meters. At both ends of the square floor, huge dwarf stone sculptures of the same height as the passage stand.

However, the passage has not been cleaned for a long time, and it is covered with dust and piles of gravel.

"These are the most outstanding dwarf heroes in Dark Fort's history. This is Mogra Dark Hammer, who is…."

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

In the half-real and half-boasted tone of the dwarf, 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 fell, the White Dragon Lord's vision gradually widened. It looked at the scene outside the door in surprise. A broken avenue with six carriages running side by side, extending from the foot of the White Dragon to the city gate outside the Dark Fort, which was two thousand meters long.

Looking at the rows of houses next to the broad road, Bailong could imagine the bustling scene of the dark furnace fort 20,000 years ago, when the shops next to the road were painted, the pedestrians on the road were swarming shoulder to shoulder.

The white dragon grabbed the guide 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 could not see at first sight. It put away its surprise and looked back at the outer city of the Dark Fort below, and had a more intuitive understanding of the glorious civilization of the gray dwarf.

On the ground below, a semicircular city wall as high as 20 meters protects the dwarf-like architectural style urban area. The end of the city is connected with a stone wall, and the gate of the inner city of Dark Fort is located at the center of the circle.

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

In the sky, Madoran was the first time to appreciate the brilliant achievements of his ancestors from a downward perspective. Suddenly, he thought of a sharp blade hanging on the head of a dark furnace castle. Maybe the mage Talong, who could fly, had a way, and immediately became excited.

"Master! Please save the Dark Fort!"

"Hmm? What's going on?" Amos asked in confusion when he felt the dwarf in his claws, his body trembling with excitement.

After a while, the dwarf suppressed his excitement.

"On the front of the city, there is a stratigraphic crack connecting the sea. The sea water spews out from the crack and pours into the underground world where we are, and its crack continues to expand."

"If this continues, in a few thousand years, the underground space where the Dark Burrow is located will be flooded by sea water. It is precisely for this reason that our tribe will continue to leave the Dark Burrow."

Hearing that the consequences were so serious, Bailong didn't say much, turned around and flew towards the direction pointed out by the dwarf. Sure enough, before long, Bailong saw Bailian, hanging down from the cracks of the rock above his head.

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

The falling sea water gathers on the ground to form a huge lake.

Looking at the vast ocean beneath him, the white dragon observed the terrain here. Fortunately, the ground here is the low end of the slope and there is an underground passage to divert the sea water. Otherwise, the dark furnace fort would have been flooded long ago.

The white dragon looked at the dome above in distress, like a sprinkler head. How can we block these leaking holes?

After thinking for a while, the white dragon had an idea. It flew into the sky, and the dragon breath was sprayed out from its mouth, spraying onto the leaking crack. Not long after, the rocks at the crack, together with the sea water in the crack, were frozen by the dragon breath.

The white dragon continued to work hard on the stone wall. First, he flexibly used fossils to make mud and turned mud into stone to seal the cracks. Then, he enchanted a magic circle that maintained a low temperature on the stone wall, completely freezing and stabilizing the moisture inside the rock.

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

During this period, the gray dwarves gradually identified with their new owners.

On the shore of the sea lake, Prince of Grey Dwarf and Lord of White Dragon stood together, watching the sea lake where the water level was extremely slowly falling.

"Have you found the passage where the Demon-Eye Tyrant came in?"

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

Half a month ago, the White Dragon Lord learned that the Demon Eye Tyrant appeared out of thin air, so he discussed and confirmed it with Soris, and finally concluded that the Demon Eye Tyrant is very likely to come from other underground worlds.

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

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

"Yes! Master!"

...

Three days later, the White Dragon returned to the White Fort, and it crawled on the Crystal Throne, and an ogre guard walked in.
Chapter completed!
