Inside the Gujia Mine.

The deeper Gu Feng went, the narrower the passage became, and he didn't know how many turns he had made, and how long he had walked, before his eyes suddenly became clear.

"It's hot!"

Gu Feng was in a cave like a stone castle, standing on a pitch-black stone slab, and before he could take a few steps forward, he felt a hot breath rushing towards his face.

And under the stone slab, about two or three hundred meters deep, there is a pool of molten slurry that constantly emits red light, which is bubbling hot, and the terrifying heat permeates the entire cavern, like an oven, as if even the air is about to burn.

Gu Feng only took a few steps forward, and the black hair snorted a few times, was burned and rolled up completely, and emitted a pungent smell.

You can see how high the temperature of the whole cave is!

"This is the Earth Source Fire Vein?" Gu Feng's eyes lit up.

This was also the first time Gu Feng had seen the Earth Source Fire Vein, he didn't expect it to look like this, and the temperature was also terrifying.

"However, this slate ...... It's so cool!"

Gu Feng's eyes were surprised, and he glanced at the pitch-black slate he was stepping on, and a trace of cool air penetrated from the soles of his feet, causing a cool air to swim around his entire body, although it could not completely resist the heat emitted by the furnace, it was enough to protect his heart and not be burned by the heat.

Raising his head again and looking at the end of the stone slab, Gu Feng's eyes flickered, and he didn't know where it led.

The whole stone slab lies on top of the molten slurry, which is also like a stone arch overpass, and the more you go to the stone bridge, the higher the temperature.

The center of the stone bridge is naturally the hottest place in the entire cave.

With Gu Feng's current cultivation, if he rushed forward rashly, he was afraid that before he rushed to the center of the stone bridge, he would already be burned to the point that he was not human, and it was even possible to break his bones.

"I'm afraid this is the source of the Earth Source Fire Vein, the energy is really amazing, and it is just right to cultivate the Fire Flame Change. Gu Feng quickly made a decision.

Although this cave is like a furnace, it is an excellent place for fire magicians to cultivate.

It's no wonder that Xu Qin, the third-grade spiritualist who died before, once said that this is the place where the fire spiritualist was created, and now it seems that it is indeed true.

Although Gu Feng was not able to absorb the power of the flames contained in the hot molten slurry under the stone bridge for the time being, in this cave, there was fire attribute energy everywhere, and it was extremely pure.

As long as Gu Feng completely absorbed the fire attribute energy floating in the air, it would be enough for him to undergo a transformation, and maybe there would be unexpected gains.

Do what you think.

Gu Feng no longer hesitated, decisively took a few steps forward, and chose a position where he could withstand high temperature baking, wanting to try his best to absorb the fire attribute energy contained in the air when his body's endurance reached its limit.

At the same time, Gu Feng secretly operated the mortal low-level spiritual skill "Fire Flame Transformation" and began to cultivate the second transformation—the Endless Flame Sea!

In addition to spiritual skills, of course, this "Fire Flame Change" also has a mantra for running fire attribute energy, which belongs to a set of spiritual skills where exercises and spiritual skills coexist!

Just like absorbing the aura of heaven and earth, Gu Feng silently recited the second transformation mantra of "Fire Flame Change", and the pores of his body opened, like a whale absorbing water, absorbing the fire attribute energy that was filled in the air around him into his body little by little.

And those fire attribute energies also emitted a little bit of firelight, quietly integrating into Gu Feng's body at a speed visible to the naked eye.

However, only a little bit of fire fell on Gu Feng's body, even if Gu Feng had already prepared and harnessed the true element in his body to wrap that little bit of fire attribute energy and protect his skin from being burned, he didn't expect that the moment the fire attribute energy was inhaled into the flesh and blood in his body, a violent and ferocious force suddenly erupted in his body.

Gu Feng immediately snorted, a trace of blood spilling from the corner of his mouth.

"Careless......" Gu Feng smiled bitterly.

Gu Feng didn't expect that just a little bit of fire attribute energy, as small as dandruff, would instantly bring him so much damage, but he also underestimated the horror of this fire attribute energy.

"Looks like you're going to have to be careful. ”

With the painful lesson of the first time, Gu Feng also became cautious this time, and did not dare to absorb it in a large area, but just compressed it in a small area, and wrapped it in a little flame with true yuan, slowly integrated it into his body, and began to absorb the pure fire attribute energy contained in it.

"Shhh

Suddenly, a sharp pain came out of the flesh and blood, as if the flesh and blood were being roasted by flames, the pain made Gu Feng grin, cold sweat kept coming out, and even his face became a little pale.

"It hurts so much!"

Gu Feng gasped for breath, his heart palpitating.

With just a little fire attribute energy, it can actually burst out with such ferocious lethality?

This was completely beyond Gu Feng's imagination, he originally thought that as long as he was careful and careful this time, he would be able to smoothly absorb the fire attribute energy, but he didn't expect to be injured once.

"Go on!"

"I don't believe it, I can't even absorb this energy!"

Gu Feng gritted his teeth, once again picked up the second transformation formula of "Fire Flame Transformation", began to absorb the fire light around his body, wrapped it in True Yuan, and carefully integrated it into his body.

Hiss!

When the true yuan withdrew and completely integrated the fire light into the flesh and blood, Gu Feng couldn't help but gasp again, but he stubbornly endured the severe pain of the burning flesh and blood, and absorbed the fire attribute energy little by little, until it was finally completely transformed into his own energy.

In this way, Gu Feng forcibly endured the pain of his flesh being burned by the flames again and again, and absorbed the fire attribute energy little by little, although the speed was as slow as a turtle, but fortunately, the situation was slowly improving, and the speed of absorption gradually increased......

It wasn't until half an hour later that Gu Feng stopped absorbing.

Disheveled!

Gu Feng raised his hand and quietly carried the mantra of the first transformation of "Fire Flame Change" to weave a fireball, and a ball of flame immediately rose up at his fingertips, then gradually grew stronger, and finally completely turned into a fist-sized fireball, constantly jumping in the palm of his hand.

On the surface, there was no difference between the weaving fireballs condensed by Gu Feng at this moment, but if you felt it carefully, you could completely find that the power of flames contained in this weaving fireball had reached an extremely pure level!

And the temperature of the fireball was all compressed inside, and even the surface couldn't feel the slightest scorching heat.

There is no doubt that after absorbing it for half an hour just now, Gu Feng also has some new understanding of the power of flames, and when he casts this first transformation fireball again, he can also control it very easily and skillfully, and even break through to a new realm.

This is also something that Gu Feng did not expect at all.

"Hey, these are ......"

Suddenly, Gu Feng was shocked and found that in his body, the flesh and blood that had been burned by the fire attribute energy just now actually had some starlight-like flames burning, and it seemed that it could burst out with even more powerful power!

"Could it be that the residue left by those fire attribute energies can still help me refine my physical body?" this thought suddenly flashed through Gu Feng's mind.

With the help of the power of flame to quench the body, this is not an uncommon thing in other places on the Fengluo Continent, but it is an extremely rare thing.

After all, how terrifying is the power of the flames?

Don't say that the warrior sucks the flames into the body, even if it is stained a little, it is enough to burn the flesh completely.

Unless they are cultivators who are crazy or some extreme martial artists, no one will choose to use the power of fire to quench their bodies.

This is completely a self-mutilating quenching method!

And Gu Feng, who was cultivating on his own, had never heard of this body refining method at all, let alone knew the horror in it, so he had some speculations just now.

"Well, try it, if you can quench your body with the power of fire, you can just train your body to be stronger. ”

Gu Feng immediately made a decision, took out a white jade slip given to him by Gu Lang from the Starlight Ring, and put it on the center of his eyebrows, the white light flickered, and soon memorized the "Overlord Body Fierce Blood Formula" in his mind, and then ran the exercises according to the above formula, and began to use the power of flames to quench his body.

But suddenly, Gu Feng was stunned, and then he remembered that the technique of "Overlord Body Martial Blood Technique" can only be cultivated by martial artists or fighters who have reached the spirit realm.

Gu Feng is still refining his body ten times, and he can't cultivate this "Hegemonic Body Fierce Blood Technique" technique at all!

"Forget it, let's wait until I absorb all these fire attribute energies first, and then come back...... Huh, what is this?"

Just as Gu Feng was planning to absorb the fire attribute energy first, trying to break through to the Spirit Body Realm for a second day, and then come to cultivate the "Overlord Body Fierce Blood Technique", the magical space in his mind, countless wonderful rune combinations, actually formed a light and shadow, and flashed red routes.

After looking at it for a moment, Gu Feng's body shook violently, and he suddenly thought of the key point, "This ...... Could this be perfecting the operation method of the "Tyrant Blood Technique"?"

After comparing it with the exercises of "Hegemony Blood Technique", he found that the light and shadow were indeed perfecting this exercise, and Gu Feng couldn't help but show joy on his face.

But soon, Gu Feng was disappointed again.

In Gu Feng's memory, every time light and shadow appeared, he could improve his martial arts or fighting skills, and complete the missing moves in the future.

If there are no accidents, it will be the same this time, and the light and shadow will evolve the mantra that is missing in the follow-up of "Hegemonic Blood Formula" to perfection.

But for Gu Feng, it was useless for the time being, and he still couldn't let him cultivate the "Overlord Body Fierce Blood Technique" and use the power of flames to quench his body.

"It seems that we have to break through to the spirit realm as soon as possible!" Gu Feng shook his palm in vain, and thought secretly.

It's just that if you want to break through to the Spirit Body Realm One Heaven, it's too difficult, you have to condense the Yuan Mansion first, and then continue to have enough True Yuan to break through in one fell swoop.

Now in Gu Feng's body, it is still a sea of qi, and there is no sign of imminent materialization.

Therefore, if you want to advance to the spirit realm, I am afraid it will take a while.

"Stopped? That's the end of the evolution. ”

After a while, in the magical space, the light and shadow finally stopped moving, Gu Feng glanced at it casually, remembered all the perfected formulas in his heart, and didn't think much about it, he wanted to draw out his spiritual power, and planned to find another way.

But at the moment when Gu Feng was about to withdraw from the magical space, his pupils shrank suddenly, and then he widened suddenly, revealing an incredible expression, and muttered, "The first level of the 'Hegemony Fierce Blood Technique', martial artists in the Quenching Body Realm can also cultivate?!!"
