The voice of the dwarf's words echoed in the cave for a long time, making the three subconsciously follow him into the broken "gate", and looked at everything around with torches and fluorite lamps.

What you can see is a very spacious room, with an area comparable to the round table Hall of red blood castle; The whole space is in the shape of a ring, with a huge column in the middle, and a circular arch design on the top of the head, as if it were directly covered on it.

Very strange.

Lucian and the oath Knight walked around for several times, groping on the walls from time to time, but they could still find several "murals" on these walls - the color had almost faded, but they could still see the general lines.

There are also several grid shaped hollows around the wall, which look like decoration, but according to the guess of the gray pupil boy, these may be the vents of the hall.

The grey pupil boy suddenly reacted that he was standing in the depths of the earth, but he didn't feel any difficulty breathing, his mind was very clear, and even his chest didn't feel any depression.

It's hard to imagine - if this hall appears in any castle of the Empire, it's probably just the living room of some poor leader... But it's in the mountains. How do these five headed dwarfs do it?!

"Lord Loren, what are you doing?"

The unbelievable grey pupil boy glanced at his eyes and found that the black haired wizard was half kneeling on the ground and groping for the floor under his feet. His expression was immediately dignified: "did you find anything?"

"Nothing." knocking the dust off his hands, Loren stood up. "Just a little curious."

Old floor tiles, surrounding walls, and the accumulated dust on them

This hall has a history of at least hundreds of years, at least dating back to the ancient kingdom... In other words, the history of this fortress is no less than that of the Dragon kingdom.

In the age of dragon Kingdom, the birthplace of Yunling dwarf people, the earliest Mithril mine

Loren felt as if he had touched some key places and was about to find out the real reason why Francis appeared in the fortress.

"It's an exquisite and ancient building, but it's not our purpose." the oath Knight's indifferent voice sounded: "I still don't see where the entrance is. Is this really the entrance of the silver helmet mountain mine?"

"Yes, it's here." the dwarf answered him stiffly, with a tone as hard as a stone: "as for the entrance... It's where you're standing now."

Where do you stand?

"I told you before I came in that the cave was formed naturally due to the collapse of the support column." the dwarf continued: "and we will build the tunnel here just to repair the collapsed part..."

One side of the gray pupil boy first touched his head, and then his face suddenly changed.

"Wait, you mean it's not here yet..."

"Of course, this is not a mine, this is just an entrance," said the dwarf Boris, pressing his right hand on the column in the center of the hall and pressing something similar to the mechanism gate.

"Dang --!"

A loud noise!

With the sound of the machine, the whole hall began to vibrate, and the dust and sand kept sliding from the top of the head and the four walls, and the shaking was more and more intense.

The indifferent dwarf still stood by the column, motionless; The stunned grey pupil boy and the oath Knight stood in place and stared at the surrounding walls.

No, no, not from around

It's underground.

Lowering his head, the black haired wizard widened his eyes and opened the "spiritual horizon" without even thinking about it

Soon, the continuous roar came from under the floor... It was still weak at first, if there was nothing, but it soon became more and more obvious and more intense.

The next second, the column in the center of the hall began to rotate slowly, and the sound of the rotation of machines and countless gears came from it. The roar around had immediately covered all the movement.

"Stand still --!" the expressionless dwarf Boris suddenly shouted:

"We're going!"

Here we go?

The stunned grey pupil boy didn't know what he meant when he felt that the floor under his feet suddenly fell, like falling directly!

The knight next to the oath also widened his eyes, closed the corners of his mouth, and his expression was extremely nervous.

Only the dark haired wizard kept his face unchanged, just kept twitching the corners of his mouth.

Yes, this looks like a huge hall. It's actually an elevator!

Of course, whether it is an "elevator" remains to be debated. With the blessing of the "spiritual horizon", Loren can only roughly perceive that the "disc" under his feet operates by countless large and small gears and levers, and does not see any circuit or the existence of similar circuits.

But the next second, he was no longer in the mood to guess these things.

"Holy Cross..."

The stunned grey pupil boy was shocked and speechless. At this moment, his expression was almost the same as that when he found the Dragon King City Nidhogg on the glacier wasteland.

Presented in front of them is a magnificent underground kingdom.

Countless "elevators" descend along the mountain wall, and countless spiral steel tracks hover in the air; The huge gear on the top of the head not only twists the "elevator" at the foot, but also rotates with the surrounding tracks and columns;

Above their heads, there are large and small "platforms" of brick and stone cities suspended and fixed in the air, like rows of pendants on the balcony, connected by stone bridges paved with steel tracks and obsidian;

Countless fluorites and moonstones fill all tracks and platforms according to certain laws. Looking up, they are as bright as the night sky, like stars.

When the three turned their eyes to their feet, a huge "steel arch" was gradually falling, and the disc appeared in front of them.

"This, this is the silver helmet mountain, this is the true face of Yunling kingdom?" Lucian looked incredible and his throat kept twitching: "I, I know... Yunling Kingdom has superb forging and engineering technology, which is beyond the reach of the Empire, but it's too..."

"No, you misunderstood." dwarf Boris said in a deep voice, "this is not the fortress city of silver helmet mountain, or even part of the fortress."

"You mean... You didn't build this place?"

"No, I mean, it's not even a city here... In the words of your empire, it's probably equivalent to the wilderness outside the countryside and those uninhabited mountain villages?" Boris shook his head:

"This is the most peripheral pit area, and it is also an abandoned pit area."

"..." Lucian.

The disc stopped steadily, and a burst of smoke and dust rose everywhere.

"Then why was it abandoned?" the oath Knight suddenly asked, "because there are not enough minerals?"

"That's just one side, a small side."

The dwarf Boris stepped forward and left the "circular hall" first, holding the torch in his hand and walking towards the direction of the steel arch: "more importantly... Yunling Kingdom has no strength to maintain such a huge underground city."

"The colonization of Byrne attracted too much labor because of the uprising; the subsequent civil war plunged countless people of Yunling kingdom into mutual fighting;

When we came back and used the settlement to fill the vacancy in the mine, we lost the colonial supplies and could not feed all the people;

So the old dungeons could only be abandoned one by one, and the surplus residents were used to fill the vacancies in each fortress... All this originated from a surname;

... Turin. "

Feeling the gaze from the front, the black haired wizard just smiled and shrugged.

Is this another version of the legend of the knight king?

The direction leading to the steel arch is a long stone road. To their surprise, there are a series of neat guardrails on both sides of the road.

But when the grey pupil boy leaned forward, he found that it was not a guardrail at all, but a grave with an iron pick.

Side by side, row upon row, countless graves.

"According to the law of Yunling Kingdom, nobles with surnames will have their own urn of ashes. Civilians, especially miners, will be buried near the mine for future generations to see their names... Because they only have names."

The figure holding a torch stopped in front of the steel arch, the nameplate on the gate glittered in the light of the fire, and Loren narrowed his eyes and looked at the words on it.

Platform 43, Ninth road.
