Under the hot magma, the naked eye completely loses the ability to see things.

Yu Fan kept his divine mind 20 meters wide around his body, and his body protected by the qi sank down.

Magma is not water, it is not completely liquid, mixed with various debris, and has a great "viscosity".

Even if you put aside the popularity, it is not easy to dive deep.

Moreover, the volcano had not completely stopped erupting at this time. Will there be an upward thrust coming from below to prevent him from diving downward?

Yu Fan has double protection of Gangqi and Zi Ribbon Clothes. There is no problem with safety for a while. The only thing to consider is the length of time.

Maintaining the body of the qi requires consuming the true energy. The deeper the dive, the higher the temperature, the faster the consumption of the true energy is.

If he hadn't returned to the ground for too long, he would obviously not be able to withstand the magma heat with his body.

"The fire-type spiritual power of this volcano seems to be stronger than the one in Peru."

After diving a few meters deep, Yu Fan felt some pressure coming from around him.

After having previous experiences, he was not panicked, but was a little funny.

Because the more powerful the fire spirit power, the more abundant the treasures contained below will be!

"Hmm? Fire Spirit Stone?"

After a while, a strong ball of fire spiritual power appeared beside him.

Yu Fan grabbed the pineapple-sized flame stone and put it on his body.

In the magma, the power of flames is surrounded by the power of fire, and the probability of this thing explosion has become much lower.

Coax ~

A thrust gushed from the bottom, pushing Yu Fan's body into a few meters above, and the protective energy dissipated a little.

Yu Fan activated his true energy to repair the qi shield and his body continued to fall.

After diving for about twenty or thirty meters, a hard thing appeared in his perception.

Yu Fan approached the past and took it into his palm and saw it, it was a red-hot metal.

After he got it, the surrounding temperature dropped sharply, revealing its original appearance - a striped metal the size of a lighter.

"What is this? It can actually remain solid under a high temperature of at least 1,500 degrees, and it is just burned red!" Yu Fan was a little surprised. He didn't know this metal.

Perhaps he noticed his harvest, the voice of the Great Banyan Tree King quickly rang out and explained: "This is called Liuyun Golden Stone, which has a hard texture and is a good material for refining magic weapons. It is more suitable for casting flying swords."

"So that's it." Yu Fan nodded, "Senior is really knowledgeable."

"Ha, do you think I have lived in vain for thousands of years? Just the things that have been stored in the Qiankun Bracelet over thousands of years are enough to produce a museum collection." The King of the Great Banyan Tree said proudly.

It is also a good harvest to get the material for a refiner unexpectedly.

Yu Fan is more interested, so he continues to search.

The opening of the Qiankun Bracelet requires the consumption of true energy. The King of Banyan Tree can only send out the things inside, but cannot take the things from the outside. Therefore, Yu Fan can only use his magic power to create an invisible "pocket" and put the Fire Spirit Stone and Liuyun Golden Stone inside. A few minutes later, Yu Fan collected more than a dozen Fire Spirit Stones, both of which are large and small.

However, the "fire spirit crystal" mentioned by the King of the Great Banyan Tree has never met.

"Go down further and dive into a depth of at least two hundred feet to get good things."

The old senior stood and spoke without any pain in his back. He did not consider whether Yu Fan could withstand the magma pressure of three hundred feet deep.

When Yu Fan dived down to a depth of more than 100 meters, he felt that the pressure on his body began to increase.

When it reaches two hundred meters, the consumption rate of true energy begins to increase exponentially.

During this period, he collected a lot of fire spirit stones and other unknown metals and mineral materials, and the "mana pocket" gradually increased.

However, it is still not enough to achieve the amount required to give Han Qingyue the best foundation-building effect.

"Senior, how should I find the Fire Spirit Crystal you mentioned? Can I find it like this..." He was a little suspicious.

"Look deeper. With your cultivation level, there is not much danger yet."

"Oh well."

Yu Fan looked in the direction of the magma again, and went down to a place a hundred feet deep from the surface.

At this time, his divine thought suddenly detected a large piece of crystal around him!

"Is it the Fire Spirit Crystal?"

Yu Fan was delighted and quickly approached the past.

With the magic power, he brought the huge crystal over here.

From close distance, looking at it with the naked eye, this is an irregularly shaped transparent crystal the size of a human head, with almost no impurities on the outside, which is much more beautiful than crystals.

Yu Fan was stunned for a moment.

The corner of his mouth twitched, "Can this be diamond?"

Diamond, that is, diamond.

But he had never even heard of such a large piece of natural diamond!

Even artificially synthesized high-purity diamonds rarely produce such large volumes.

"Boy, why are you picking up this garbage? You don't have any spiritual power at all, and you can take up space in vain."

Yu Fan:...

"Senior, this thing is very valuable." Yu Fan said quietly.

Although I know that the price of diamonds is speculated by capitalists, the actual value is far less high.

But if you don’t throw it out at once, you can break it and sell it slowly. It’s still easy to sell it for one billion or eight billion.

Tang Lingxue happened to open a jewelry store, and it was most suitable to take it back and give it to her.

The King of the Big Banyan Tree disagreed and said, "Money is something outside of your body. I am not as vulgar as you. Look for it quickly, don't delay it for too long, and you will die here after exhausting your true energy."

"I know, I know."

Yu Fan curled his lips and searched everywhere with his spiritual thoughts.

At this time, the pressure on him was already quite high, and he did not dare to go deeper blindly, so he could only search around.

The range of divine thoughts is limited, so finding things is not fast.

He searched for about ten minutes, and his true energy was consumed to a level of only 40%.

A lot of fire spirit stones, rare metals, ores were collected, but the whereabouts of fire spirit crystals were still not found.

Just as he was about to give up and planned to use "one thousand" fire spirit stones as the result of this exploration, suddenly, a hot force appeared at the end of his divine perception.

At the same time, the King of the Great Banyan Tree exclaimed: "What a pure fire essence! Boy, come and take a look!"

"Um."

Yu Fan moved his body and walked through the viscous magma to the hottest place of the flame.

In front of him was a ball of golden material like sludge, flowing in the magma, but it was clearly separated from the magma and was not dissolved.

The heat of this ball of golden sludge is unprecedented in Yu Fan. The temperature is more than ten times higher than that of magma, at least 20,000 to 30,000 degrees!

Not only that, the spiritual power emitted by him is also powerful and scary, even stronger than a practitioner with a fourth-level cultivation level!

If he hadn't seen it with his own eyes, he would have even mistakenly thought that someone with his cultivation level was also exploring the treasure underground.

"What is this? Why does it feel even more terrifying than the Earth Fire Tribulation!" Yu Fan said in a frightened heart.

The terrifying high temperature forced him to increase the output of his true energy and make the protective energy thicker in order to barely resist it.

Even so, he was still sweating all over his body due to heat, and hot steam kept coming out of his body.

The King of the Banyan Tree did not directly answer.

After a while of silence, I said in a strange tone: "Your lack of knowledge really makes me feel embarrassed. This is the essence of the earth vein and the spiritual root of fire. Even in ancient times, it was very rare. It represents the root of a spiritual vein. As long as you get it and combine it with some other raw materials, you can shape a spiritual vein by yourself at any time."

The root of the spiritual vein!

Yu Fan was shocked on the spot.

He asked, "If I take this thing away, will the veins near Mara City not be able to rise?"

"Of course." The King of the Great Banyan Tree said confidently: "When the essence of the earth veins is taken away, the earth veins will gradually fade and dissipate. Only when a new earth veins essence grows in the heart of the earth can it be changed."

"Then can this thing be used to build a foundation for my sister-in-law?" Yu Fan asked again.

"Well..."

The King of the Big Banyan Tree was a little hesitant, "Her physique is very fragile. Such a powerful spiritual root may not be absorbed, so he can only give it a little at most. Otherwise, even if I have a guardian of the Dharma, I may explode and die."

"This thing should be able to reach the Fire Spirit Crystal, right?"

"Barring, this is a priceless treasure. Do you think you can do it?" The King of the Banyan Tree said angrily.

"Well, thank you senior, I understand." Yu Fan nodded with a smirk on his face.

He saw his magic power surge. With one hand, he waved his hand and directly put everything in the "mana pocket" and the essence of the earth veins into the Qiankun bracelet.
