How could there be magic fluctuations in this? It was clear that it had reached the deepest part of the vein, and it stands to reason that there should be nothing underneath.

Li Yunfei frowned, and a raging flame instantly ignited on his arm, and then began to vibrate at an extremely high speed.

I saw him put his palm on the rock wall, like a high-speed drill bit, and quickly shook the ore on the rock wall.

The pit that had been one meter deep extended inward again, and in the blink of an eye, it had penetrated a full meter deep.

Feeling that the magic fluctuations were getting stronger and stronger, and at the same time, there was a hollow echo of "bangbang", Li Yunfei understood that the rock wall in front of him was no longer very thick, and it was likely to be opened up immediately!

Then he no longer used the method of shaking his palms, but directly clenched his fists, aimed at the rock wall in front of him, and smashed them down with a fist.

The stones on the stone wall fell one after another, and the hollow echo became louder and louder, and in the blink of an eye, he could already tell by the sound that there was only a layer of less than ten centimeters thick left on the rock wall.

At that moment, Li Yunfei took a deep breath and punched it hard.

"Boom!" There was a loud bang, and the rock wall in front of him shattered, turning into a large hole with a diameter of more than one meter, and the dazzling light and heat wave instantly poured out, making everything around him impossible to look at.

It's all lava down there!

"Boom", at the moment when the magma gushed out, the surface of Li Yunfei's body instantly ignited with the power of flames, and at the same time quickly closed his eyes.

The red-hot magma completely enveloped Li Yunfei in it, and if it weren't for his own flame power and metal dragon skin, he would have been severely burned by now. After all, his human body is not the same as the giant body, and the human body is still made of flesh and blood.

At this time, with the skin of a metal dragon, the hot magma was only similar to the temperature of the water to him. Of course, the density of the water is relatively large, and he can't open his eyes, so he can only move forward with his senses.

After gradually adapting to the density of magma, Li Yunfei was like swimming, and a fierce man plunged into the cave in front of him.

At this time, all the clothes on his body had been burned to ashes, and the whole person was swimming in the magma underground like a swimming fish.

Unexpectedly, the magma in the center of the volcano in the distance actually connected to the bottom of the entire Flame Township, and now I think that the reason why there is such a vein of fire demon crystals in the Flame Township is precisely because of this.

At this time, he couldn't open his eyes to see the surrounding situation, but Li Yunfei completely released his spiritual power and felt the surrounding situation, which was not much different from opening his eyes.

He felt the strong waves of magic and swam towards the heart of the waves.

Due to being in the magma, the surrounding fire elements were extremely active, and had even reached a level close to materialization, Li Yunfei only felt that the fire elements in his body were also rapidly accumulating, and his fire magic seemed to be growing rapidly!

He didn't pay much attention to his own magic ability, so although he was an earth elemental resonator, and he had the magic talents of fire and gold, his own magic power was extremely disproportionate, but he didn't expect to find a shortcut by mistake.

It seems that I will have to take a dip in the lava often in the future. Li Yunfei thought secretly.

Ten minutes later, he had already dived a hundred meters in this magma again, and the temperature around him was getting higher and higher, even if he had the power of fire and the metal dragon skin, he felt a little unable to hold it at this time. In particular, although this metal dragon skin is hard, it is not very heat-insulated, and Li Yunfei's blood is about to boil.

Just when he was about to give up, there was a sudden light in front of him, and then a sense of falling appeared instantly, and the whole person fell downward, and the feeling of being wrapped in magma around him disappeared in an instant and turned into air!

Li Yunfei suddenly opened his eyes, and immediately saw that he had appeared in a hollow giant hole at this time, saying that it was a hollow, perhaps it would be more appropriate to describe it as "bubble".

As far as the eye can see, an invisible force forms a hollow bubble that isolates all the surrounding magma. The whole bubble is the size of a stadium!

In the center of the giant bubble is an altar-like structure towering over, radiating colorful light. Obviously, the power that isolates the magma comes from this altar. This thing is the size of a basketball court, and it looks mysterious and quaint.

Li Yunfei instantly operated the Burning World Flame Extinguishing Technique, and the Burning Heaven Fighting Qi in his body operated, driving the power of the iron bones of the stars and pulling the power of the stars.

It's just that at this time, he is already deep underground, and he can only faintly feel the power of the stars.

However, the power of these stars was enough, and Li Yunfei used his strength to change direction in mid-air and rush towards the altar.

At the moment when he swept through the air, Li Yunfei looked down and felt that this huge magma bubble was like an amber, and he was a worm wrapped in amber.

I don't know what is the core of the earth under this magma? Is it a small planet like the world once was?

At this moment, a shadow struck, and Li Yunfei immediately reached out and grabbed it lightly, landing on the edge of the altar.

What makes a difference is that the altar is cold and comfortable.

Looking up, Li Yunfei couldn't help but gasp.

Around the altar, there are more than a dozen crystals the size of a human head, and they are of different colors, some green, some earthy yellow, some red, blue, and so on. The red crystals exude a scorching breath and a crimson glow, the blue crystals exude an icy aura, the green crystals exude a fresh aura, and the earthy yellow ones exude a heavy aura, and so on and so forth.

The surface of these crystals looks like magic crystals, but inside it seems as if there are liquids of various colors flowing.

Thinking of this, Li Yunfei casually took out an identical crystal from the space ring and looked at it, and immediately strengthened his thoughts.

Can't be wrong, there are more than a dozen magic marrow inlaid around this altar!

Who is this who is so extravagant to build such a magnificent altar?

Luxury, too extravagant!

You must know that there are only a few magic marrow in a magic crystal vein, and many magic crystal veins even only have a piece of magic marrow, and there are more than a dozen magic marrow on this altar, and they have all kinds of attributes.

This shows that these magic marrows come from many mineral veins with different attributes! The essence of so many mineral veins is actually placed here at this time, which can really be called a big deal.

"Ding", with a soft sound, Li Yunfei stepped on the altar. At this time, he suddenly realized that he looked down again, and his expression was incredulous.

He also has a lot of precious materials in his hands, the most common and the most used of them is Mithril. And judging by the sound, the whole altar at his feet is a huge piece of mythril!

If you look closely, you can see that this altar is covered with all kinds of grooves, and it is an alchemy circle carved from Mithril!

"These formation circuits are not things that are now, not even things that have been in the past few hundred years!" Li Yunfei said to himself with an excited face.

As an alchemist, his level has at least reached the strength of a great grandmaster, and he has even mastered techniques far beyond this era, and through Karis's alchemy notes, he also knows the alchemy of hundreds of years ago, and the moment he saw these alchemy circuits, he had already concluded that these things were definitely products of the ancient era.

It can be seen that there are still a lot of redundancy in the entire alchemy circuit, but there are also many extremely amazing designs, which are enough to show that the designer's whimsy is very effective.

In the half-dimensional temple of life in Azeroth, and when he was hunted down by Evans, he had seen that kind of teleportation circle in ancient times, and now it seems that the alchemy circuit on this altar also has some similar shadows, but it is definitely not used for spatial teleportation.

This should also be a space circle.

Thinking of this, Li Yunfei stepped forward and walked forward, and the moment he came to the second floor, before he could speak, Lao Yan's voice had already sounded instantly: "Who the hell is this such a loser? How can he use so many ghost crystals as ordinary building materials? God, it's outrageous! Crazy! Rich and capricious!"

Hearing this, Li Yunfei looked carefully at the ground of the second layer, and saw that this layer was completely composed of a transparent crystal, and there was a trace of something like blood stains swimming inside this crystal, which was a rare material close to the divine material, ghost crystal!
