The mountain walls around the magma lake are engraved with countless ancient patterns, which seal the underground magma lake, which is why it is now like a furnace, and the temperature is constantly rising.

Zhou Yuan stood on the rock wall, he felt the temperature here, and his face was slightly condensed, he had not yet penetrated into the magma lake at this time, but the high temperature had already made his skin tingle slightly, which showed how terrible the temperature in the depths of the magma should be.

And these complex light patterns were carved by Xi Jing with his help, and what he did was to create this unique cultivation environment.

This is also necessary for cultivating the "Purgatory Great Flame Demon".

Zhou Yuan patted the Qiankun bag on his waist with his palm, and suddenly a lot of light flashed, and boxes taller than people appeared in front of him.

When the box was opened, it was filled with some crimson spars, and the spars faintly had white smoke rising and exuding a terrible temperature.

These are fire smoke crystals, which are materials that can only be formed after thousands of tempers in the depths of the earth, which absorb the fire source qi from the depths of the earth and contain high temperatures.

Zhou Yuan flicked his fingers, and all the fire smoke crystals in those boxes poured down towards the magma lake.

Boom!

As those fire smoke crystals fell, the magma lake suddenly turned into huge waves, the crimson color became more and more deep, the temperature began to skyrocket, and even the void was slightly distorted.

After doing this, Zhou Yuan didn't stop, he took out dozens of various kinds of rare materials, and then dumped them all.

If you want to cultivate the "Purgatory Great Flame Demon" and other top-notch body refining small holy arts, just this cultivation environment is extremely harsh, which requires the deployment of many rare materials, fortunately, Zhou Yuan's identity in the Heavenly Abyss Domain is different, otherwise, with his previous identity as the chief pavilion master, I am afraid that he is not qualified to squander it wantonly.

By the time he had done everything, it would be a full hour later.

At this time, he looked at the magma lake again, only to see that in the lake, there were a lot of red light crystal dust flickering, and the terrifying temperature made the corners of Zhou Yuan's mouth twitch slightly.

According to his perception, at this time, with the magma lake, some of the weaker ones jumped into it in the early stage of the Tianyang Realm, and I am afraid that they will not last long before they will be turned into ashes.

And he's going to cultivate here...

This "Purgatory Great Flame Demon" is really terrifying, and if you want to cultivate it, you don't know how much suffering you have to suffer.

Call.

Zhou Yuan took a deep breath, but his eyes became firm and sharp, how can there be easy power in this world, others only say that he has repeatedly created miracles, but they have never thought about how much effort has been paid after this miracle...

He stepped out, and his figure fell directly.

Poof!

His body crashed into the lava lake.

The magma flooded in from all directions, and the terrifying heat swept in.

Zhou Yuan's skin was burned in an instant, his flesh and blood were also squeaking, and the hair on his body was burned clean.

The burning pain erupted, and at this time, Zhou Yuan seemed to be melted, and there was no look on his bloody face.

The Purgatory Great Flame Demon is extremely domineering, if you want to cultivate this technique, you must require your physical body to have a good foundation, otherwise your physical body is too fragile, and if you jump down at this time, I am afraid that it will be too late to cultivate, and your physical body will be directly burned clean.

And Xi Jing would choose such a small holy technique for Zhou Yuan, obviously because Zhou Yuan perfectly met this point.

In the flesh and blood, there is a jade light blooming out, resisting the erosion of high temperatures, and there is a force full of vitality in the flesh and blood that is rapidly repairing the burned skin, flesh and blood... That's Taiyi green wood marks.

In the depths of the magma lake, Zhou Yuan sat quietly, his flesh and blood were constantly burned and repaired at this time.

But fortunately, this first level has finally survived, because only by maintaining the physical body in this harsh environment can you really start cultivating...

Zhou Yuan shook his palm, and a red jade slip flashed out of his palm.

His spirit poured into it.

Rumble!

There was a roar in my mind, and at that moment, it seemed that a volcano between heaven and earth was erupting, and endless red magma meteors fell from the sky.

And under the ravages of the magma meteor, there is a huge crimson demon shadow, standing between the heavens and the earth.

The shadow was covered in crimson magma, and when it opened its mouth, a torrent of magma erupted, and the whole world was turned into a sea of fire.

Zhou Yuan's mind froze, and he visualized the Great Flame Demon in his mind.

When the visualization began, his physical body also began to change faintly, only to see that some of the flesh began to transform into a red color like magma, and the blood flow all over his body also became more powerful.

An indescribable fiery force surged inside the body, like a flame in an iron furnace, calcining the iron in it, quenching its impurities.

Zhou Yuan's flesh and blood became thin little by little under that kind of calcination, and in some places, even bones could be seen.

This kind of cultivation obviously requires a great deal of suffering.

However, although it was painful, Zhou Yuan forcibly gritted his teeth and persisted, because he could feel that as his cultivation continued, a new golden blood began to be born in his heart... It's been a long time since I've seen that!

This Purgatory Great Flame Demon is worthy of being the top alchemy little holy art! Its power and subtlety are far beyond the Xuan Holy Body.

However, contemplating this Great Flame Demon and refining the physical body requires the power of consuming the origin of the law domain, and there are not many origin of the law domain in this red jade slip, if it is an ordinary person who cultivates, I am afraid that the daily visualization time will be strictly controlled.

But for Zhou Yuan, this is not a problem.

Because in the stone statue of the Law Domain in the depths of the Nine Domains Assembly, he had obtained a large number of Law Domain Origins.

With the support of these Domain Origins, Zhou Yuan was obviously able to wantonly visualize the Great Flame Demon, and that kind of cultivation speed would be far faster than ordinary people, which was also the reason why he had the confidence to initially cultivate the Great Flame Demon within this month.

As soon as his mind moved, the origin of the law domain in the Divine Mansion began to drain.

Feeling the consumption of these rare powers, Zhou Yuan did not have any heartache, these origin of the law domain was not a power that he could control at this time, so since it could be used to cultivate the source technique to enhance his own strength, there was no need to hide it.

In the future, when it is stronger, it will naturally have the opportunity to obtain more legal origins.

His mind fell silent, allowing the terrifying temperature of his body to rage against his body, and the roar of a volcanic eruption seemed to echo inside his body.

The underground magma world was silent, except for the sound of the magma bubbles bursting.

And a month's time passed quietly when Zhou Yuan cultivated in the depths of the magma.
