"You react quickly, it's Thor's hammer. ”

Zoltan nodded slightly, and said solemnly: "But you may not know that Thor's hammer has gone through five masters, and Elfa the Great is only the fourth. The first three owners are all from the Dwarven Supreme King of the Ironbeard Clan, because the Hammer of the Thunder God was forged by the Ironbeard Clan with the power of the clan as the treasure of the Zhen Clan. ”

Wren's heart flickered.

There have been dozens of supreme kings in the history of the dwarves, and it is very rare for the Ironbeard Clan to have three, and it is obvious that this legendary warhammer is an important factor.

And the fortress under Longshande was established by the Ironbeard Clan.

The relationship between this made Wren immediately understand why Zoltan mentioned Elfa the Great.

He asked with some excitement, "Elfa the Great entered the Ironbeard Underground Fortress, got the Thor's Hammer, and then came out of it?"

"Yes. Zoltan said: "Not only Elfa the Great, but the fifth master of Thor's hammer, Walden, who claimed to be the successor of the Great more than a thousand years ago, also lived in Longshande for many years before becoming famous, and he must have also entered the Ironbeard Fortress. ”

"Walden the Usurper?" Wren knew about the man.

Walden was also a well-known figure in the history of the empire, with a mixed reputation.

Born into a family of blacksmiths, he later became a transcendent, originally unknown, suddenly got out of nowhere the hammer of Thor, which had been missing for thousands of years, performed many amazing heroic feats, and claimed to be the rightful successor of Elfa the Great, with great strength, trying to force the emperor to abdicate.

The emperor at that time was also a powerful figure, of course, he refused to give up the throne, and Walden also had a large number of supporters behind him, and the two sides launched a series of struggles.

This turmoil lasted several years and swept the entire empire.

The end result was a surprise to everyone.

The Emperor was killed in the conflict, and Walden was mortally wounded by the Assassins, and it is still unknown who did it, which has become a famous historical mystery.

Walden's supporters, in order to avoid being purged by his successor, slaughtered the entire royal family, and Elfa the Great's bloodline was cut off and imperial power died out.

Since then, there has been no emperor in the empire, and the ruling power has fallen into the hands of the "Supreme Council of Cermitius".

Thor's hammer, which caused the trouble, disappeared again after Walden's death.

Wren thought quickly in his heart.

Thor's hammer was a treasure forged by the Ironbeard Clan, and the dwarves evacuated Hosquintak, and years later, Elfa the Great obtained Thor's hammer and established an empire.

The Orion Empire was officially established in the year 221 of the New Era, and the Dwarven Evacuation was around 1,200 years before the New Era, with an interval of more than 1,400 years in between.

When the dwarves leave the underground fortress, they will definitely take the hammer of Thor with them.

However, more than a thousand years later, Elfa the Great obtained this legendary warhammer from the Ironbeard Underground Fortress.

Elfa the Great died after fifty years of reign, and Thor's hammer was nowhere to be found until it was obtained by the usurper Walden around 1350 AD, another interval of nearly 1,200 years.

After Walden's death, the hammer disappeared again and has not been seen since.

These clues were connected, and Wren had a guess in his mind.

"Looks like you've guessed it. Seeing his expression, Zoltan smiled proudly and said, "I found out from an ancient book of the Ironbeard Clan that the main material of Thor's hammer is an extremely rare Void Meteorite Steel, which has the ability to travel through space, and it is very likely that every time it disappears, it returns to the place of birth, that is, the Ironbeard Underground Fortress. ”

Wren's eyes lit up when he heard this, and he couldn't help but pound his heart.

Zoltan shook his head and said seriously: "This is just our speculation, not necessarily correct, you don't have too much expectations." ”

"And it's a legendary weapon, and even if it's there, it's impossible for you to take it with you. ”

"You should know better than I do about the rumors of Mjolnir. ”

Zoltan said these things only because he thought that Wren would be interested, and not really wanted to enter the fortress specifically to find the legendary warhammer, which was not his purpose.

"I understand. Wren nodded slightly, exhaled a long breath, and suppressed the excitement in his heart.

Thor's hammer is known as the heaviest weapon in the world, so it is also nicknamed "World Crusher", and in various legends, Elfa the Great put his war hammer on the ground and let others try it, but no one can lift it.

Whether it's a human, elven, dwarf, or giant, troll, or dragon, no matter how powerful you are, you can't shake the warhammer in the slightest, it's amazing.

The secret of raising Thor's hammer is known only to the owner of the warhammer.

But no matter what, Wren didn't want to miss such an opportunity, and at least made a trip to the underground fortress, even if it was good to take a look, so as not to regret it in the future.

He didn't hesitate any longer and said, "Zoltan, I'll go in with you." ”

"Good. Zoltan was very happy, and then said: "I'll go and tell Roger, you go back and have a good rest, and we'll go in tomorrow morning." ”

"Do you need any special preparations from me?" Wren asked carefully, he had no experience in this area, and there was no harm in asking for more advice.

"No, I'll get it ready for you. Zoltan looked confident.

Wren was relieved, Zoltan had been planning for so many years, he was a dwarf, and this time he entered the dwarven underground fortress, just like returning to his own home, he shouldn't go wrong.

He didn't say anything more and returned to Vigo Manor.

That night, Wren told Viola about this, and she was surprised but did not object, and wanted to give Wren her space necklace and let him take it.

Renma refused.

This space necklace is the most precious thing left by Viola's parents, most of her net worth is in it, without the necklace, her strength will be weakened by at least half, in case someone plots against her during this period, it will be too dangerous.

Wren didn't want to put Viola in danger because of himself.

This time when you enter the underground fortress, and Roger, the legendary witcher, is accompanied by you, safety is guaranteed, and there is no need to bring a space necklace.

He only accepted a few potions from Viola, and refused everything else.

The next day, Wren arrived at the Basil Hotel early in the morning.

In the mechanical workshop, Roger stood at the door of the secret room, looking at the rune circle inside.

"Master Roger. Wren said hello.

"Hmm. Roger replied lightly.

Wren found that the Demon Hunter's complexion was much better than some time ago, there were no dark circles under his eyes, his cat-like eyes were also extraordinarily bright, two cross swords were behind his back, he wore strong leather lock armor, and his figure was tall, revealing a strong aura.

"Why haven't you seen Lord De Lerza lately?" he asked.

"Ever since she killed that Shadow Blade Slayer, De Lyresa hasn't been here. There was some resentment in Roger's tone.

"Uh......" Wren didn't know how to comfort him, thinking to himself, no wonder Roger's complexion had changed for the better.

At this time, Zoltan came in from outside, and he gave an account of everything about the hotel, and did not say where he was going, but only said that he would leave for a few days.

Closing the entrance to the mechanical workshop, pulling a large box out of the corner, Zoltan began to gear up.

First, he wore a complete set of gray-silver rune armor, then a heavy double-edged battle axe, two soul guns, five or six rounds of ammunition belts wrapped around his waist, and behind his back was a half-human-high metal box, which was filled with all kinds of things, including a dozen pieces of various tools, large bags of compressed dry food, alchemical water collection rods for drawing water, etc., and a lot of messy things, I don't know what it was for, it was simply a treasure chest.

The most striking thing is a brick-thick book, tied with iron chains at both ends of the spine and hanging diagonally from Zoltan's waist.

Noticing Ren's gaze, Zoltan slapped the book hard, making a thumping sound, and said: "This is an ancient book obtained from the Ironbeard Clan, which records a lot of the contents of the Ironbeard Underground Fortress, as well as a brief map, whether we can gain this time depends on it." ”

Wren nodded, opened his phone library, and found that the book appeared on the list, so he immediately downloaded it.

Turning the pages of the book in the interface, they are all written in dwarven script, which is incomprehensible.

However, the dozen or so maps are very simple, from the bottom, divided into many layers, each layer is marked with a few key points.

"Alright, let's go inside. Zoltan took the lead in stepping into the rune circle.

Wren checked his shotgun and bullets, pulled the Ice Crusher hammer from the dragon's leather belt, and stood in the circle.

Only Roger was still outside the doorway, his face full of confusion.

Wren laughed secretly, he had already discovered that Roger had teleportation phobia, and all the magic related to teleportation was not easy to touch.

Zoltan was also very clear about this, and the two looked at Roger and did not rush him.

Roger muttered a few times, and finally stubbornly walked into the range of the rune circle like an execution ground.

Zoltan wears a pair of mechanical glasses that resemble goggles, which inspires the attached dark vision.

A spell came out of his mouth.

The entire rune array immediately lit up, vibrating slightly for a few seconds, the air was filled with a faint magical energy, and the space in front of him gradually distorted, and the sky swirled, as if falling into a huge whirlpool, and the whole body was weightless, which made people panic in their hearts.

This feeling lasted for a short time.

In the blink of an eye, Wren found that he was no longer in the secret room.

The powerful effect of the will of truth made him not feel any discomfort during the teleportation, and when he glanced around, he found that it was pitch black and there was no light source, but under the dual effect of the soul eye and the will of truth, the darkness did not form any obstacles.

As far as the eye can see, there is a huge cavern.

No matter which direction you look at, you will eventually be blocked by the stone wall, which is a dome more than 30 meters high, supported by huge square stone pillars, under the columns, the stone houses are endless, forming a large building complex.

These stone houses are high and low, some are dug out of the wall, some stand on the ground, and there are a large number of stone steps, squares, and statues, all of which are magnificent and have a strong dwarf style.

Despite the thousands of years that have passed, most of the buildings are still intact, with only a few collapses and a thick layer of dust everywhere.

The entire cavern was dead silent.

Wren's voice of all things, I didn't hear any sound, but the air in my breath was normal, not as dull as I imagined, and there was a faint slight flow.

This discovery made his heart slightly relieved, and if the air can flow, it means that there is an outlet.

"We're in!"

Zoltan first watched vigilantly for a few seconds, but found no danger, and couldn't help but cry out with joy.

Roger next to him held his forehead and shook it violently a few times, as if he had not recovered from the dizziness caused by the teleportation, his eyes were confused, and his face was a little pale.

"Where is this?" Wren asked.

They were in a small square paved with intact stones, and the surrounding area was very empty, and the rune circle on the ground was not obvious.

"I'll take a look. Zoltan opened the ancient book around his waist, the pages of which were made of metal sheets, and when they were turned around, they made a crisp sound.

"According to the book, the entrances to the five rune circles are distributed in different locations in the fortress, from the first to the fifth floor, one on each floor. ”

"It's a residential area, most likely a second or third floor. ”

Wren also searched for information about the Dwarven Fortress on his phone.

Whether it is the World Mountains, the birthplace of the dwarves, or the regions outside the World Mountains, the underground fortresses of the dwarves are generally similar in structure.

A dwarven fortress, generally divided into ten floors from below.

The first layer of the most surface is the line of defense against foreign invasion, usually heavily guarded, a whole floor is barracks and watchtowers, guarding the passages downward, built armories and fortresses, the overall area is not very large.

From the second floor to the fifth floor, there is the main living area of the dwarves, where kings, clan elders, and commoners mostly live in these four floors, and all life-related facilities, thrones, shrines, bars, and markets are concentrated on these four floors.

The sixth floor is a farm where mushrooms are grown, as well as factories and furnaces.

Floors 7 to 9 are the treasure troves of the fortress, containing a large number of relics, as well as the tombs of the dwarves, and the most important mines for the dwarves.

The tenth layer is the lowest layer, and there will basically be several underground rivers as water sources, and there may also be enemies entering the fortress from the dark rivers, and the terrain is complex and chaotic.

Zoltan was quick to recognize.

"This is the third level, and we're going to the fourth, where there is the Temple of Moradin, most likely housed rune technology. ”

Wren asked, "Which way?"

This cave has several exits that lead in different directions.

"I don't know, so I can only look for it as I go. Zoltan scratched his head, this is a fortress built thousands of years ago, like a huge underground labyrinth, even dwarves can easily get lost.

The three of them walked along the wide road and chose a random direction.

Walking on the road, looking at the tall and magnificent buildings on both sides, Wren had a sense of insignificance, and couldn't help but think, why do dwarves like to build houses so big when they are not tall?

Moments later, the trio passed through a hewn stone passage into another cavern.

The terrain of this cave is deeper, and you can see the whole picture from the exit of the passage.

Wren's gaze swept over the scene in the cave, and suddenly saw something that obviously did not belong to the dwarf, and suddenly his face changed slightly, and he reminded in a low voice:

"Someone has been here!"
