Saint Sovereign of Nine Heavens

Inside the cultivation room, the array glyphs flashed a faint and gentle brilliance, and the Essence Qi was already dense to the point that it was like a fog. Chen Yu sat cross-legged in the cultivation room, the array glyphs flashed a faint and gentle brilliance, and the Essence Qi was dense to the point that it was like a fog.    

Chen Yu was still holding the Primeval Stone in his hand. The surface of the Primeval Stone was also glowing and a dense amount of Essence Qi was seeping into Chen Yu's meridians through his palm.    

Chen Yu was naturally familiar with Primeval Stone. In Bloodfire Emperor's memory, he had seen this kind of thing a lot.    

The common gold and silver did not have any value to the high rank warriors and they did not have much purchasing power. The Primeval Stone had replaced them and became the currency used by the warriors to trade.    

According to the quality, Primeval Stone could also be divided into upper, middle and lower ranks. In Chen Yu's hand was a low rank Primeval Stone. Just by looking at the effects of the Essence in it on warriors, it was equivalent to twenty Tier 2 Spirit Dans. From this point of view, an Inferior Grade Primeval Stone would be worth around a hundred thousand gold.    

However, in the sect, gold was seen as a useless commodity and s were used as the basis for trade between warriors. Therefore, the price of a single Primeval Stone was not high in the secular world, and a single Primeval Stone could be sold for hundreds of thousands or even millions of gold taels.    

This Primeval Stone did not have much use in Chen Yu's closed door cultivation, but it could continuously provide Essence. Adding on the Medicine Pill and the essence gathering array that was powered by the Demon Crystal, Chen Yu would be in great trouble if he did not have any zhenqi.    

Suddenly, Chen Yu's body started to tremble lightly. Following which, the elemental energy whirlpool around him started to spin rapidly.    

Chen Yu's clothes suddenly swelled with a swishing sound.    

Immediately after, the origin energy whirlpool that was thought to be the center of Chen Yu's body suddenly became chaotic. Near Chen Yu's shoulder area, a small whirlpool the size of a palm appeared.    

Chen Yu's trembling body suddenly stopped at this moment and became quiet.    

The whirlpool that had appeared was attracting the elemental energy of the entire cultivation room. It gradually grew larger, and had the intention of replacing the huge whirlpool with the original one.    

However, two hours later, Chen Yu's body suddenly trembled again. At this moment, his brows were knitted together with a hint of pain.    

Next, a second small whirlpool appeared near Chen Yu's left knee.    

With the appearance of this second whirlpool, the initial huge whirlpool had already begun to crumble. Chen Yu's body also stopped shaking at this moment.    

This was not the end. Four hours later, Chen Yu's body trembled again. The intensity of the vibration was higher than the previous two times. Soon, a third whirlpool appeared on Chen Yu's back.    

When the third whirlpool appeared, the original whirlpool had completely disappeared. The three whirlpools revolved around each other, forming a resonance with an indescribable mysteriousness.    

The three swirls constantly pulled the Yuan Qi in the training room into the swirls, constantly expanding until the three swirls connected with Chen Yu, creating a strange and twisted equilibrium.    

This process continued for an entire day.    

One day later, Chen Yu's body trembled again and a fourth whirlpool appeared on Chen Yu's right elbow.    

Six hours later, a fifth vortex appeared.    

After nine hours, a sixth vortex appeared.    

At this point, the six swirls around Chen Yu's body once again appeared to be twisted and strange, with a mysterious and contradictory balance.    

Three days later, the seventh whirlpool appeared on top of Chen Yu's head.    

Another day passed, and an eighth vortex appeared.    

Three days later, the ninth whirlpool appeared in Chen Yu's lower abdomen. As soon as the whirlpool appeared, it quickly expanded and swallowed the eight whirlpools.    

Chen Yu's body was shaking non-stop. His clothes were rustling non-stop. He was bloated to a high point as if he could explode at any moment.    

Chen Yu's brows were tightly knitted together. He revealed a pained expression from time to time, but his expression was still highly focused.    

At this moment, there were two Qi whirlpools clearly separated inside his dantian. One of them was above his head, and his aura was light, sharp, and agile. It was the Astral Qi that he had just formed. The other was at the bottom, heavy and soft.    

Of course, these two qualities were only relative!    

Between the two vortexes, a thick Qi was rapidly rotating like a spiral, connecting with the Supreme Qi Vortex. This rotating Yuan Qi was like a coiling dragon spinning, the higher it went, the more agile and sharp it became.    

The true energy whirlpool below was shrinking.    

This was precisely the final step in the transformation of true qi into astral energy.    

In the last ten days, Chen Yu had already completed his Nine Revolutions Divine Technique and was only missing the last step.    

Since the Nine Revolutions Divine Technique was called the Nine Revolutions Transcendental Tower, it naturally needed to undergo nine transformations to condense the astral energy to an incomparably sharp and pure level. Every time one condensed the astral energy, it would be accompanied by the transformation and fusion of the true energy and the astral energy.    

As time passed, the distinct gale and true energy whirlpools in Chen Yu's Dantian continued to grow. The gale whirlpool grew bigger and bigger, while the true energy whirlpool became smaller and smaller.    

Finally, after the Zhen Qi vortex shrunk to a small enough size, the column of Yuan Qi connecting the two swirls suddenly shattered. At the same time, a drastic change started to happen in his Dantian.    

It was as if the heaven and earth were being tossed back and forth. The whirlpool of Supreme Qi that was originally above the Dantian suddenly broke and expanded, covering the entire Dantian. It began to flow into the meridians like a tidal wave.    

The whirlpool of true qi also disappeared and was drowned by the tide of astral qi.    

At this moment, Chen Yu's body violently shook. Along with the sudden flow of the Astral Energy, the clothes on his body suddenly exploded into pieces. The dense and sharp Astral Energy at the moment of breakthrough was undoubtedly unstable, and a portion of it spread out through his pores.    

First level of Heavenly Astral Stage!    

Chen Yu suddenly opened his eyes and let out a long exhale. It was hard to hide the fatigue in his heart, the continuous flow of Qi Condensation that lasted for more than ten days caused him to have the urge to sleep for a whole day.    

However, Chen Yu knew he had to first control the berserk Aura. If the Astral Energy was lost after the breakthrough, it would not be difficult to make up for it in the future, but it would inevitably be a waste of time.    

In fact, Chen Yu had still underestimated the difficulty of his Qi Condensation becoming astral. The nine months he spent in the Tower of the Secret Realm had caused his true energy to be extremely rich and refined, which was originally a good thing for the formation of astral energy. However, he hadn't expected that his true energy had also gained a trace of a strange, wear-resisting quality, which was why his Qi Condensation becoming astral used up a lot of his mind.    

Of course, the existence of this special characteristic also made the condensed Astral Energy that Chen Yu refined become pure to an unimaginable level!    

Circulating the Profound Heaven Spell, Chen Yu started to control the unstable Supreme Qi in his body.    

Six hours later, Chen Yu had gathered all the unstable energy into his Dantian and was able to control the ruyi. He put away his cultivation technique and stood up to carefully feel the changes in his body.    

Chen Yu felt that his body was more agile and his strength had also increased. Moreover, because his true qi had been converted into astral qi, many organs which could not be nourished by true qi during Qi Condensation Stage could be easily permeated with astral energy, causing his body's physique to once again begin a process of strengthening!    

"No wonder many martial artists omitted this step of body refining. After breaking through the Heavenly Astral Stage, the dense and sharp astral energy reached deep into every organ in the body and continued to refine them, causing the body's functions to become even stronger and the bones and flesh to become tougher and denser. This is also equivalent to body refining!"    

With a sigh, Chen Yu punched towards the sky.    

The Astral Energy was rapidly released through his meridians. As his fist tore through the air, it carried a sharp and unstoppable power.    

"Astral Energy Condensation!"    

With a low growl, Chen Yu struck out with his palm, focusing all of his attention on the Astral Energy that was being spat out from his palm.    

The moment the cyan colored gale broke through the air, it rapidly contracted and condensed into a short sword, thrusting out.    

However, after the long sword condensed to a length of about a foot, it could not continue to grow. It could only shoot out under the control of Chen Yu's telepathic thoughts and hit the wall, causing it to explode. It left a huge mark on the wall created by the special materials in the training room and almost broke through the wall.    

"The astral energy is too refined, it's already not inferior to the mid or late stages of Heavenly Astral Stage!" Even with Bloodfire Emperor's memory, Chen Yu was still shocked by the power of this [Astral Energy Condensation]. In his memory, when Bloodfire Emperor broke through Heavenly Astral Stage, the degree of refinement of his [Astral Energy] had never reached this level!    

To a Heavenly Astral Stage practitioner, the more refined the Astral Energy was, the more difficult it would be to condense it.    

On the contrary, the more the Astral Energy wavered, the easier it was to condense it, and correspondingly, the weaker it became.    

There were even some martial artists who had barely broken through Heavenly Astral Stage. Their true qi was not completely condensed into astral form, and when it was released, their true qi and astral energy mixed together. It seemed like a terrifying momentum, but it was actually not able to withstand a single blow.    

After confirming that the degree of refinement of the Pure Aura was far greater than expected, Chen Yu also had a clearer understanding of himself. If he were to fight against Su Jingyuan now, he was confident that he could kill him within one or two moves through the released Supreme Force!    

"However, because the astral energy is too refined, it is instead insufficient in thickness. Wanting to break through the second level of the Heavenly Astral Stage in one go, however, is not something that can be done in a short span of ten days!" Chen Yu looked a little surprised but also a little helpless.    

If the Supreme Force was too refined, the benefits would be very obvious. When fighting with enemies, Chen Yu's Supreme Qi could easily break and tear apart the opponent's Supreme Qi. But at the same time, it would also bring about the drawback of cultivating. Chen Yu needed to spend even more effort in cultivating his Heavenly Astral Stage.    

In addition, Chen Yu's already powerful physique could absorb more heaven and earth origin energy than ordinary martial artists. This way, the amount of martial arts resources Chen Yu needed in his Heavenly Astral Stage was even more shocking.    

However, after thinking about it, Chen Yu felt that this problem wasn't worth it to him!    

One could find and fight over the martial dao resources, but one could always come up with a solution. But refining the Supreme Force was not something that could be done so easily. It represented the thickness of a martial artist's foundation. It had an immeasurable impact on the height that a martial artist could reach!
