Torches, braziers, furnaces, fire pits, fire ditches formed by ironmaking residues, dotted with stars, strips and blocks, as far as the eye can see, these fires reflect the whole copper mountain exceptionally brightly.

It doesn't look stuffy, and it doesn't seem difficult to breathe.

Mina explained to the two that it was thanks to the dwarves' ventilation facilities, and that although their lung capacity was exercised, they still had to breathe!

They didn't dig for the veins they mined, they left vents where they dug and those vents formed a vast air circulation system that allowed all life inside the mountain to survive, and more importantly, for the dwarves to smelt metal in the caves!

The dwarves' dedication to making iron in the cave has led them to develop such a perfect method of excavation, which is indeed not something that humans want to imitate.

This also made Qin Wei and the Gray Girl even more amazed by the dwarves' methods.

The Hematite Pit is the largest pit in the Copper Mountain, the size of a small city in the Carolingian Kingdom, and is home to the dwarven king Ironstone Magman.

The difference between hematite pits and ordinary pits is very simple, that is, there are more and denser heat sources in the hematite pit, and if you suddenly feel a heat wave coming towards you while walking, it is close to the absolute center of the copper mountain.

The dwarves were able to construct a very good level of ventilation, but they couldn't afford to put up a stove everywhere, so the temperature here was noticeably higher by a few degrees.

Mai Na, who led the way, was accustomed to this kind of hot and dry environment, while Qin Wei and the Gray Girl, two "outsiders", were obviously a little overwhelmed by this temperature.

This act of summoning spells made Mina scream again, because the probability of producing a mage among the dwarves was not very high, so although the gray girl still couldn't say a few complete words to him, he was more and more respectful of this female elf.

"I can't enter the Jinshi Hall when I get to it, I can only ask the guards to convey the message of your visit, and I can't say if the king will see you!"

Minah reminded again as she approached the dwarven king's palace with the two of them.

"Understood! I'm so sorry for you!" Qin Wei was really grateful to this dwarf.

Obviously, he just told Mai Na about the elves, which made Mai Na lead them all the way, although this was a process of discussing with Mai Na, but Qin Wei always felt as if he had taken advantage.

Qin Wei added a little apologetically, "Then after you arrive at the Golden Stone Hall, you can go about your business, we have delayed you a lot of time!"

But these words did not make Manna very happy, and he blew his beard and glared and exclaimed, "That will not do! Our dwarves speak as heavy as a lump of gold! I will wait outside with you before you are called into the main hall!"

The dwarf's expression was very serious, and there was probably no way to change this decision, so Qin Wei could only smile bitterly and respond.

And in front of the Jinshi Palace, Maina really stood with Qin Wei and them after informing the guards.

"Look, there will be a quick response to your request, we dwarves have always done things simply!"

Mana was referring to the temple guards who trotted all the way to deliver the message.

However, Qin Lao's mind was not on the other party's attitude of using running messengers, but also on the other party's equipment with gray-white armor carved with exquisite patterns, as well as weapons made of the same material.

That material Qin Lao is very familiar with, he has a handful of the same material around his waist, which is made of a material that can be immune to magical effects.

And unlike the "poor" Qin Grade, who only picked up a short knife transformed by a demonic suppression stone, the whole body of the hall guards was covered with this material, which was completely stone armor and weapons, if it weren't for the fact that their bodies were almost full of patterns, the motionless hall guards would be no different from a stone.

Mai Na saw Qin Lao's eyes shining when he stared at the equipment on those guards, and his first reaction was that this plant tribe had never seen this thing, so he said ostentatiously, "Boy, the guards here are from the Demon Breaking War Group! Have you heard of the Demon Breaking War Group!?"

"Of course I've heard that the most elite troops in Tongshan are all said to be made of demon-suppressing stones, and now I see that this is really the case!"

"Yo! You kid is quite knowledgeable, do you still know the magic suppression stone!?"

Mai Na's tone sounded like he was ridiculing Qin Rank, but he was actually very happy when he heard Qin Rank praise the Demon Breaking War Group as "elite".

And Qin Wei's next action immediately stopped his state of joy.

Qin Wei directly took out the short knife on his waist and shook it in front of Mina and said, "Of course I know! And not only do I know, but I also captured a piece from the orc!"

Huh~ Mai Na noticed that the material of the blade was familiar when Qin Lian took out the short knife, and the color and pattern on it seemed to be similar to the equipment on the Demon Breaker Clan.

The dwarves knew that some of the Suppressor Stones were out of the Copper Mountain, but it was still not an easy thing to get their hands on, and the people who could get their hands on that material were either rich or expensive, so Manna only thought that the short knife was just modeled after the Suppressor Stone.

But as soon as Qin Lai said something affirmative, he was not calm, he immediately thought about taking the short knife over to take a closer look, but due to the height difference, Mai Na could only snatch the short knife from Qin Class's hand by jumping.

Don't look at the short and thick body length of the dwarves, but the mobility is not bulky at all, Mai Na started the jumping movement quite quickly, the little short legs bent slightly and then exerted force, the body rose off the ground, and then hooked the short knife in Qin Lao's hand into his arms.

This move made Qin Wei cry and laugh, he felt that if Mai Na wanted to see it and talk to him directly, wouldn't it be over if he handed it over?

But this also reminded him that Mai Na was a friend so it was okay to let him drag him away, and if the enemy sent the short knife out so easily, wouldn't it be dead?

Qin Wei secretly kept an eye on himself, and decided to hold it tightly and raise it higher the next time he took out the short knife...

On the other hand, Maina was holding a short knife and observing it as carefully as she was identifying a treasure, and muttered.

"Huh!? Alas, this sea snake pattern is the family pattern of the Weiss family, and then look at the dense texture of this stone! Oops~ This is really a magic suppression stone! You kid actually didn't lie to me!"

"But this magic suppression stone is a little rough! Look at the particles and unevenness on the back of this knife!
