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

Yu Fan kept his divine thoughts at a width of 20 meters around his body, and the body protected by Gang Qi sank.

Magma is not water, it is not entirely liquid, mixed with all kinds of debris, and has a great "viscousity".

Even the heat aside, diving is not easy.

And at this time, the volcano has not completely stopped erupting, and there will be an upward thrust from the bottom to prevent him from diving down.

Yu Fan has the dual protection of Gangqi and purple ribbon clothes, and there is no problem with safety for a while, the only thing that needs to be considered is the length of time.

The deeper the dive, the higher the temperature, the faster the consumption of the true element, the happier the speed of consuming the true element.

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

"The fire spirit of this volcano seems to be a little stronger than the one in Peru. ”

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

Having experienced it before, he was not panicked, but a little funny.

Because the more fire spiritual power there is, the richer the treasures contained underneath will be!

"Huh?"

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

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

In the magma, surrounded by the power of fire, the probability of this thing exploding is significantly lower.

Coax~

A thrust gushed from underneath, pushing the sail's figure upwards for a few meters, and the body guard was a little sluggish.

Yu Fan urged Zhenyuan to repair the Gangqi shield, and his body continued to fall.

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

Yu Fan approached the past, and when he fished it in the palm of his hand, it was a red-hot metal.

When he got it, the temperature plummeted, revealing its true form - a strip of 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 only burned red!" Yu Fan was a little surprised, he didn't know this metal.

Probably sensing his gain, the Great Banyan King's voice quickly sounded, explaining: "This is called Liuyun Golden Essence Stone, which has a hard texture, and is a good material for refining magic weapons, and is more suitable for casting flying swords. ”

"I see. Yu Fan nodded, "The seniors are really well-informed. ”

"Heh, do you think the old man has lived in vain for thousands of years? Just the things that the Qiankun bracelet has stored in ten thousand years are enough to produce a museum. The Great Banyan King said proudly.

Accidentally getting a refining material is also a good gain.

Yu Fan became more interested and continued to look down.

The opening of the Qiankun bracelet requires the consumption of true yuan, and the Great Banyan King can only send out the things inside, but cannot collect the things from the outside world, so Yu Fan can only use his mana to make an invisible "pocket" and put the fire spirit stone and the flowing cloud gold essence stone inside. A few minutes later, Yu Fan successively collected more than a dozen fire spirit stones, both large and small.

However, the "Fire Spirit Crystal" mentioned by the Great Banyan King has never been encountered.

"Further down, dive at least two hundred feet deep to get good things. ”

The old-timer didn't have a backache when he stood and spoke, and he didn't consider whether Yu Fan could withstand the pressure of magma three hundred zhang deep.

Yu Fan followed the crooked magma vein, and when he dive to a depth of more than 100 meters, he felt that the pressure on his body began to increase.

At two hundred meters, the consumption rate of True Yuan began to increase exponentially.

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

However, it was still not enough to achieve the amount needed to give Han Qingyue the best foundation building effect.

"Senior, how should I find the Fire Spirit Crystal you said, can I find it like this......" He was a little skeptical.

"Look a little deeper. With your cultivation, there is not much danger at this for the time being. ”

"Oh well. ”

Yu Fan searched for a while in the direction of the magma gushing out, and went down to a place a hundred zhang deep from the surface.

At this moment, his divine mind suddenly detected a large crystalline body around him!

"Could it be the Fire Spirit Crystal?"

Yu Fan was overjoyed and quickly approached the past.

Mana pulled, and the huge crystal was brought over by him.

Up close, with the naked eye, this is an irregularly shaped transparent crystal the size of a human head, with almost no impurities on the outside, much more beautiful than the crystal.

Yu Fan was stunned for a moment.

The corners of his mouth twitched, "This can't be a diamond, right?"

Diamonds, that is, diamonds.

But such a large piece of natural diamond, let alone seeing, he had never even heard of it!

Even synthetic, high-purity diamonds rarely produce such a large volume.

"Boy, what are you doing picking up this garbage, you don't have any spiritual power at all, you take up space in vain. ”

Yu Fan: ......

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

Although it is known that the price of diamonds is all speculated by capitalists, the actual value is far from that high.

But such a large piece, as long as it is not thrown out at one time, it is broken and sold slowly, and it is still easy to sell it for one billion and eight billion.

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

The Great Banyan King disagreed, and said, "Money is something outside the body, and the old man is not as vulgar as you." Hurry up and find it, don't delay it too long, the true yuan is exhausted and dies here. ”

"Got it, got it. ”

Yu Fan pursed his lips and scattered his thoughts to search around.

At this time, the pressure on his body was already relatively great, and he didn't dare to go deeper blindly, so he could only search around.

The range of divine thoughts is limited, and the efficiency of finding things is not fast.

He searched for about ten minutes, and the true yuan was consumed to the point that only forty percent was left.

A lot of fire spirit stones, rare metals, and ores have also been collected, but the whereabouts of the fire spirit crystals have not been found.

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

At the same time, the Great Banyan Tree King exclaimed, "What a pure Fire Yuan Force! Boy, go over and take a look!"

"Hmm. ”

Yu Fan's body moved, shuttling through the viscous magma, to the place where the flame breath was at its hottest.

In front of him, there was a lump of golden mass of soft mud, flowing in the magma, but distinct from the magma, undissolved.

The heat of this golden ooze was unprecedented, and the temperature was more than ten times higher than that of magma, at least 20,000 degrees Celsius!

Not only that, but the spiritual power emanating from his body was also strong and terrifying, even stronger than a cultivator of the Quadruple Heavenly Cultivation!

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

"What is this? How does it feel more terrifying than the fire of the Earth Fire Tribulation!" Yu Fan said in shock.

The terrifying high temperature forced him to increase the output of the True Yuan and make the body protection qi thicker in order to withstand it.

Rao was still sweating from the heat, and hot water vapor kept coming out of his body.

The Great Banyan King did not answer directly.

After being silent for a while, he said in a strange tone: "Your unfamiliar appearance really makes the old man feel ashamed." This is the essence of the leyline, the fire spirit root. Even in antiquity, it was very rare. It represents the root of a spiritual vein, as long as you get it, and then use some other raw materials, you can shape a spiritual vein by yourself at any time. ”

Spiritual Roots!

Yu Fan was shocked on the spot.

He asked, "What if that is...... If I take this thing away, won't the leylines near Mara City be able to rise?"

"Of course. The Great Banyan King said firmly: "If the essence of the leylines is taken away, the leylines will gradually decay and dissipate, and only when a new essence of the leylines grows in the center 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...... this"

The Great Banyan King hesitated a little, "Her physique is very fragile, and I am afraid that such a powerful spiritual root cannot be absorbed, so she can only give a little at most." Otherwise, even if there is an old man protecting the Dharma, he may explode and die. ”

"This thing should be able to withstand the fire spirit crystal, right?"

", this is a priceless treasure, do you think you can afford it?"

"Well, thanks senior, I see. Yu Fan nodded, with a wicked smile on his face.

I saw his mana surging, and with a wave of one hand, he directly included everything in the "mana pocket", as well as the essence of the leylines, into the Qiankun bracelet.

The Great Banyan King hurriedly opened up an independent small space in the small world, lest the flame aura be too heavy and burn Han Qingyue to ashes.
