Because it is not magical, the transparent world is not hindered by the magic stone mixed with the hardest metal door, and the internal structure of this metal door is completely presented in front of Riege's eyes.

Rig relied on the open world of his senses, groping for the hardest metal door in front of him, and he didn't know when the noise around him would disappear.

At some point, the people of the Loki clan stopped their discussion, and they all looked at Rig, who was reaching out and groping in front of the door, and closed their mouths as they looked at each other.

Especially Finn and Ace, looking at such Lige, their hearts moved slightly.

Ace was vaguely aware of something by virtue of her understanding of Rige.

Finn, on the other hand, saw Rigg groping for the hardest metal door there, as if confirming something, and squinted his eyes before suddenly speaking.

"Can it be broken?"

Finn's words made everyone look at Rieg in unison.

Only then did Rieger come to his senses.

He didn't nod his head, he didn't shake his head, he just said.

"You can give it a try."

The hardest metal of oralcum, this thing is not easy to break.

If Rig exerts all his strength, then there is still a way to do it, but in this state when he has just entered Lv.6, his "strength" parameters are not even as good as Grace, and Grace can't do it, so he naturally can't do it.

Coupled with the fact that the magic stone was in the way, the effect of magic was weakened, and Li Ge really didn't dare to say that he could easily destroy the hardest metal door.

Of course, he wasn't completely out of the question.

As long as you pull out the holy spear and wake up Rengominiade, the hardest metal is just debris on the side of the road, which can be easily annihilated, but then it is not only the hardest metal door that will be annihilated, but also the entire labyrinthine city.

The same goes for the rest of the spells that are powerful enough to destroy the hardest metals and slayer stones, either tactical or strategic, and if used, at least Daedalus Road will collapse.

Rig still has the magic to pick locks, but that kind of functional magic will definitely be hindered by the magic stone and will not work.

Li Ge even suspected that he used the [Present Break] that could cut off the space to split this door made of the hardest metal, and after being weakened by the Demon Removal Stone, the released [Present Break] would not be able to destroy the door.

Therefore, in the case of taking into account Olari and avoiding causing casualties around her, there is a high probability that magic will not be able to deal with this door made of the hardest metal.

Unless Rig is willing to drain his experience points and use the [Wish to the Stars], he can only use pure physical attacks to try to break the hardest metal door.

But it's hard to do that without going all out.

Fortunately, Rieg still has a transparent world.

"Use the permeable world to find out where the structure of the hardest metal door is relatively weak, and attack it."

"Since this door is mixed with the Demon Removal Stone, there must be a weak point in the presence of impurities."

"As long as you find that weak point, it may not even be able to resist the super-hard metal wall next to it."

Therefore, it is the hardest metal door that Rieg wants to destroy, not the super-hard metal wall.

And that weak point, he has already found.

"Bang!"

Suddenly, a frighteningly hot flame erupted on Rig's body.

"What——!"

"Rieger......!?"

Everyone in the Loki clan was frightened, and they all exclaimed in surprise, and subconsciously moved away from Rige, avoiding the oncoming heat wave and flames.

The temperature in the air is constantly rising.

Covered in flames, Rig slowly pulled out his weapon——— Black Knife Hermit.

Yes, instead of using the Sword of the Fool, Rig took out his own exclusive Nihon Sword.

After all, in terms of power alone, the hermit is much stronger than the hermit, and there is no reason not to use it at this time.

Unfortunately, the people of the Loki clan did not notice this scene, but were attracted by the vision generated by Rige's body.

“…… What is this? ”

"Additional magic of fire?"

"Rig also learned this magic?"

Bert, Diona, and Thiogne spoke out one after another.

The former had an ugly complexion, as if he had seen something that made people feel unhappy, while the latter two were purely surprised, and had the same expression as the people around them.

"No, it's not magic." Riveria spoke, staring closely at Rig, who was covered in flames, and said, "I didn't feel the magic power on Rig's body, let alone the magic array. ”

Everyone's faces suddenly changed slightly.

Ace's transparent golden eyes rippled.

"It's breathing."

The blonde swordswoman, who had already learned the breath of the wind, discovered this with great ease.

It was discovered that Rige's breathing rhythm had changed, becoming more violent and powerful than when using Wind Breath.

So, Ace also discovered another thing.

"It's a breathing technique that is stronger than the breath of the wind."

To be more precise, this breathing method is much stronger than the Wind Breath, and is far from even a level thing.

Discovering this, Ace's eyes were even more turbulent.

The rest of the people were also full of surprise.

"This is the kind of thing called breathing?"

"But that's too powerful, isn't it?"

"I see, does this kid still have a hidden hand?"

Diona, Theogne, and even Grace spoke up.

Under such circumstances, the flames on Rig's body kept rising, forcing everyone to retreat again and again, and finally even retreated from the ground, returning to the entrance of the cave leading to here.

"It's so hot! How can it be so hot? ”

Loki, who only has an ordinary human physique, can't stand it anymore.

"What the hell is breathing? It's hard to have such a powerful spell even with additional magic, right? ”

The rest of the people are also you look at me, I look at you, some are speechless, some are surprised, and once again they are shattered by Rieger's cognition.

Rig didn't know all this, but kept concentrating, making the transparent luster in his eyes shine brightly, and dyeing his pupils translucent silver.

Until a certain moment, Riege, who was refining the precision of his breathing and constantly raising the power of his breathing method, raised his knife and let the flames follow the trajectory of the knife, leaving bursts of fireworks in the space.

"Breath of the Sun: Seven Type ......"

The flames swelled again, filling the entire space.

"Yang Hua Tu!"

The flames burst out like a storm, causing a ring of flames on the hermit's pitch-black blade, which rippled around the storm-like flames.

Rig, who had used his strongest breathing technique, swept out like a firelight, and slammed into one of the hardest metal doors.

"Boom !!"

The hardest metal gate that made the city's strongest faction, the Loki clan, feel intractable, burst open under the storm of flames, and completely shattered.

The flames poured into the passage behind the door, raging in the passage.

The entire underground base suddenly shook violently, and the aftermath did not stop for a long time.

…………

Underground, in the dark hall where the stone pedestal is located.

"Wow!"

The grim reaper, dressed in tattered black, was shaken by the sudden jolting of the hall and almost fell, but it was only with great difficulty that he stabilized his body and let out a cry.

"What a great boy! Even the hardest metal door that is so thick has been destroyed! It's a rumored monster newcomer! ”

Thanatos, not knowing whether he was excited or stunned, shouted in a somewhat high-pitched voice.

"Damn it!"

Beside him, the man with sunken eyes and a gloomy face couldn't help but be furious as he watched the hardest metal door appear on the water film being shattered, and the passage behind the door was also scorched black by the flames.

"Destroying this man-made labyrinth?"

"Do you know how much effort and sacrifice it took us to get to where we are today and build this labyrinth to the scale it is today?"

"How dare you act so unscrupulously against the creatures here...... Damn, damn it, damn it! ”

The man was furious and completely subverted the dark image given to people.

"Well, don't worry, Brother Baka." Tanatos pressed the man's shoulder and said with a smile, "This is a necessary loss, and after the Loki clan is settled, there will be no one in this labyrinth city to hinder us." ”

"When the time comes, you can continue to complete this labyrinth left by your people through generations of unremitting efforts with all your heart, and no one will hinder you."

"So, how about you concentrate on dealing with these villains who are trying to get in the way of you and me?"

In Tanatos' smiling reassuring voice, the man named Baka gradually calmed down and stopped being angry.

It's just that his eyes staring at the water film no longer moved away, staring at the figure that appeared in the flames that soared into the sky, as if he wanted to remember his appearance, remember everything about him, and the anger in his eyes had turned into hatred.

"Let's get started." Baka lowered his voice and said coldly, "I don't want to see this guy continue to stay in this labyrinth anymore. ”

"Okay, okay, don't worry." Thanatos patted Baca on the shoulder, as if he was playing with something, and smiled, "The show is about to begin, let's wait and see." ”

…………

“————”

On the one-way passage covered with stone slabs, the flames were still raging, undulating in all directions, making the place a sea of fire, and the smell of scorching heat was constantly exuded.

"Hoo ......"

Standing in the middle of the fire, Rig exhaled to dissipate the flames that had wrapped around him, and returned the black knife to the sheath, and sent the hermit back to the storage space of the dimensional cube once again with the knife in its sheath.

Having succeeded in destroying the hardest metal gate, Rig raised his head and looked at the one-way street in front of him when he entered the world inside the door.

"Is this the man-made labyrinth Knossos?"

Artificial labyrinth Knossos.

This is a great work of the past that no one knows of its existence, let alone seen its face, and has been silently carved out under Eulali for hundreds of years.

The first person to build it and draw its design was none other than ——— Daedalus, the designer of Daedalus Road.

The great craftsman was so fascinated by the grandeur and mystery of the dungeon that he came up with an earth-shattering idea.

That is, to use your own hands to build a second dungeon.

The artificial labyrinth Knossos is the product of this earth-shattering idea.

Now, Rig has broken in, into another dungeon ——— even the guild doesn't know exists.
