In addition to the magma lake in the center of the earth, there are many places, and there are often some large and small holes on the ground, bubbling with magma bubbles.

Anna walked cautiously, she felt that the ground was too fragile, there was always a feeling that the ground would sink as soon as she exerted her strength, as if it were a trap, or that kind of deadly trap, after all, it was a lot of magma that fell down to greet her, which was not a joke.

Because it is too dangerous, it will be seriously insecure, and every step has to be taken carefully.

The surrounding air was filled with the pungent smell of sulfur dioxide, and the air temperature was also very high, Chen Nai estimated that at least sixty degrees were close to seventy degrees, and the closer to those magma, the higher the temperature.

They all had items on them to protect against the heat, so they were naturally worried and afraid, but the dwarven craftsmen who forged or hammered the metal here were not protected, and they were naked, wielding hammers and constantly beating.

There was no sweat, but their faces and skin became red.

The sound of the bell is endless, and even intertwined, forming a special melody, which is a little messy but with the atmosphere in front of them, but it gives people a special feeling, and it seems to be a little enthusiastic.

None of the dwarves cared why Anna and Chennai were here, their eyes were only on their hammers, the red, hot metal, the weapons that were about to be forged.

So unimpeded to the magma lake, this magma lake is not small, the width completely occupies the entire underground space.

When I got closer, I realized that there was a small area in the center of the magma lake, which seemed to have a hammer in the center.

After Chen Nai took a closer look, he could be sure that there was indeed a hammer there.

"Why is there a hammer there?"

"Oh, that's, that's the Stormhammer, the dwarven artifact."

"The artifact of the dwarven race is placed in this kind of place......"

Chen Nai felt that something was wrong, after all, this place was too spacious, don't you think it's too conspicuous here?

But if you think about it carefully, the safety factor is very high here, and it is not easy to come here to snatch it, not to mention that this is an exclusive artifact of the dwarf race, without the blood of the dwarf race, you can't exert any power if you take it, and whether you can pick it up is one thing.

"Yes, it's been here for almost two thousand years, and it is generally not used unless there are special circumstances."

When Anna said this, a whining gust of wind blew, and this gust of wind was very strong, driving a strong heat wave, and the temperature of the air with it also rose a lot, reaching a level of nearly 100 degrees in an instant.

With this level of high temperature, even the magic shield was infiltrated, and Anna and Chen Nai were sweating all at once.

The temperature of magma is indeed very high, about 700 to 1,200 degrees, some temperatures are relatively high, some are relatively low, the difference is also obvious, just look at the brightness, those places that are red and glowing, the temperature is naturally the highest.

Between 700 and 1,002, this level of temperature is enough to melt the rock and most of the metals with a lower melting point, but there are many metals whose melting point is higher than the temperature of magma, so even magma cannot melt it, it just softens it.

For example, iron, the most common metal, has a melting point of 1,500 degrees, which is not something that magma can easily melt.

It is not difficult to melt iron, the magma itself has such a high temperature, it only needs a little means to make the heat continue to increase, and the temperature can be raised to more than 15,000, or even 2,000 to 3,000 temperatures, with the ability of the dwarves, it must be easy to do.

But what about metals that are more precious and rare, with higher melting points?

3,000 degrees is indeed very high, but as far as the few precious metals that Chen Nai is exposed to now, they can not be melted at a few thousand degrees, or softened for reprocessing.

Take that extraterrestrial meteorite as an example, just 3,000 degrees is like itching, there is no difference.

So how did the dwarves use this fire in the center of the earth, the heat of the magma to melt it and forge it into weapons?

Chen Nai had been thinking about this problem before, after all, if he relied on the magic technology of the underground factory to manufacture alloys on a large scale, then the problem of temperature would have to be solved.

There is no magma on the side of the underground factory, and this kind of ready-made thing can be fully utilized, so Chen Nai also has a little headache, thinking about whether he can find a way to refer to it from the side of the dwarves.

In this way, Chen Nai did find a way, but he couldn't copy this method.

To put it bluntly, the dwarven method is to rely on the characteristics of the Storm Hammer to suppress the magma at the same time, but also fully mobilize the heat and transport it to the forge of the dwarven craftsman, so that the temperature can easily be raised to more than 1,500 degrees, close to 2,000 degrees.

The reason why it can't be copied is very simple, Chen Nai doesn't have an artifact like the Storm Hammer on hand, it can act as a temperature control center, and the replica is naturally just a joke.

However, looking at this masterpiece of the dwarf clan, it gave Chen Nai a little inspiration, that is, electromagnetic heating, and the temperature of this seems to be good.

When I get back in the evening, I'll talk to Ospark about it, and experiment to see if it works.

"Master Cat, can you feel it, where is the stele?"

"Oh, sorry, I was distracted."

Just thinking about the alloy and heating just now, I didn't take a serious look at it to confirm the whereabouts of the stone tablet, and now I was reminded by Anna, Chen Nai just entered the state.

"It's definitely not running here, it's just that I can't pinpoint its exact location, there are too many sources of interference."

After carefully sensing it, Chen Nai could be sure that the stele was indeed here, but he only sensed a rough idea, and there was no way to accurately grasp the location, and there were too many interference factors.

The heat wave emanating from the magma lake is one of them, but it is not the main thing.

The main thing was the impact of the Storm Hammer, which formed a huge network when it mobilized and transported heat, which seriously interfered with Chen Nai's perception.

"However, this area is also very large, and there is magma everywhere, how can we find it?"

As far as the eye could see, except that magma was magma, Anna could see that her head was big, and she really didn't know where to find it.

Can this be found, Anna has no confidence at all.
