Countless ancient runes were carved into the walls around the lava lake. These runes completely sealed off the lava lake below, making the place akin to a cauldron with a constantly rising heat.

Zhou Yuan stood on the cliff, his face turning a little solemn as he felt the heat wash over him. The high temperature was already faintly tingling his skin, a small taste of how frighteningly hot it would be when he ventured deeper.

Chi Jing had helped inscribe the runes to create this unique training environment for Zhou Yuan because the environment was necessary to cultivate the Purgatory Great Flame Devil art.

Zhou Yuan patted the spatial bag at his waist. Light rapidly flashed around him as several cases appeared, each case as tall as a human.

The cases opened, revealing their insides filled to the brim with scarlet-red crystals. Faint white smoke rose from the crystals as a terrifying heat rippled from them.

These were fire smoke crystals, a material that would only form deep underground after being refined thousands of times. The crystals absorbed the fire Genesis Qi deep underground and gave off extreme heat.

With a flick, Zhou Yuan sent all the fire smoke crystals pouring into the lava lake.

Rumble!

Giant waves rose from the lake as its scarlet-red hue deepened. The temperature began to rise at an alarming pace, and even the air started to distort a little.

Zhou Yuan did not stop there. He took out several dozen different rare ingredients and also threw them into the lake.

The environmental conditions to cultivate the Purgatory Great Flame Devil art was exceptionally demanding and required a mix of numerous precious resources. Fortunately, Zhou Yuan had a very special position in the Tianyuan Region. Otherwise, a mere chief pavilion master would never be allowed to waste resources so freely.

The preparations were complete two hours later.

When one looked towards the lava lake again, one would see a lot of scarlet-red crystal dust sparkling within it. The terrifying temperature made the corners of Zhou Yuan’s mouth twitch a little.

He had a feeling that some of the weaker initial Heavenly Sun experts would quickly turn to ash if they jumped into the lake.

And he had to train in this very same lake...

The Purgatory Great Flame Devil art was truly terrifying. Who knew how much suffering it would take to master it?

Huu.

Zhou Yuan took a deep breath as determination arose in his eyes. There was no such thing as an easily gained power in this world. Others only saw how he repeatedly created miracles, but how could they imagine the amount of effort behind each one?

He took a step forward, and his body plummeted from the cliff.

Splash!

His figure fell straight into the lava lake.

Lava rushed towards him from every direction, accompanied by a dreadful heat. It instantly burned Zhou Yuan’s skin, and his flesh groaned in misery as all the hairs on his body burned away.

An intense burning pain erupted. Zhou Yuan felt as if he was being melted; however, the mangled flesh on his face made it impossible for anyone to tell what expression he was wearing.

The Purgatory Great Flame Devil art was an extremely tyrannical skill. To learn it, one needed to have a body with good foundations. If one’s body were too weak, it would be burnt to cinders even before cultivation could begin.

Chi Jing had chosen this body refining little Saint Art for Zhou Yuan because he perfectly fulfilled this condition.

Jade light began to blossom within his flesh to withstand the dreadful heat’s invasion. Abundant life energy rapidly repaired his destroyed skin and flesh. It was the handiwork of the Tiayu Green Wood Mark.

Zhou Yuan silently sat deep inside the lava lake as his body underwent a continuous cycle of destruction and regrowth.

He had thankfully endured the first trial. Only when the body was able to survive in this harsh environment would he be able to begin training.

Zhou Yuan clenched his hand, and a scarlet-red jade strip appeared in his palm. His Spirit quickly entered it.

Boom!

A loud boom rang out in his head. It seemed as if a volcano was erupting, causing endless lava to rain down from the sky.

Amidst the falling lava, a giant scarlet-red devil towered over the land.

Lava flowed down the devil’s entire body, and it even spat molten rock from its mouth, turning the entire world into a sea of fire.

Zhou Yuan focused and began to visualize the great flame devil.

A small transformation began to occur in his body. Some of his flesh turned scarlet-red like magma as the blood in his body began to circulate with more force.

An indescribable searing energy rose within his body. The energy was like the flames in a furnace, refining a piece of metal and purging it of its impurities.

Zhou Yuan’s flesh seemed to turn transparent little by little, such that even bone could be seen at several parts of his body.

He was clearly under a tremendous amount of pain.

However, Zhou Yuan stubbornly gritted his teeth and endured. He could feel new drops of golden blood being produced in his heart, a phenomenon that had not occurred for a very long time!

The Purgatory Great Flame Devil was indeed a top-tier body-refining little Saint Art! It far surpassed the Mythic Saint Body in both power and profoundness.

However, the process consumed Law Domain Source, and there was not much left in the scarlet jade strip. An ordinary practitioner would use it very sparingly each day. But this was no problem for Zhou Yuan because he had obtained a tremendous amount of Law Domain Source in the Law Domain statue from the nine regions tournament.

With his supply of Law Domain Source, Zhou Yuan could indulge as he pleased. Hence, he could progress in his cultivation far faster than any ordinary person. This was one of the reasons why he was confident in reaching the elementary level after a month.

With a thought, he began to consume the Law Domain Source in his Divine Dwelling.

Zhou Yuan did not feel any pain at the loss of the precious energy. The Law Domain Source was not a power he could wield in his current state. Since it could be used for a Genesis technique that could strengthen him, there was no need to hide it away.

When he grew strong enough in the future, there would naturally be a chance to obtain more Law Domain Source.

He remained composed as he allowed the terrifying heat to wreak havoc in his body. It was as if a volcano was erupting within him.

The underground world of magma was completely silent. Only the popping of magma bubbles could occasionally be heard.

A month quietly passed.
