"Whew, it's time to refine this Demon Heart Crystal. ”

After spending most of the day pranayama, Ye Chenfeng finally adjusted his state to the best, preparing to refine this demon heart crystal that was pregnant with mysterious blood.

"Well, there is no demonic energy in this Demon Heart Crystal!"

When Ye Chenfeng carefully refined the Demon Heart Crystal, there was no demonic energy vented in the Demon Heart Crystal, which made him a little surprised, hesitated for a moment, controlled the consummation sword momentum wrapped around the tip of his fingers, forcibly cut his chest, and put the Demon Heart Crystal into the bloody chest.

The Demon Heart Crystal entered his body, and Ye Chenfeng immediately felt that a stream of violent magic power melted into his flesh and blood, rampage through the criss-crossing meridians, destroying his own body.

"Soul Eater, Refining!"

Ye Chenfeng forcibly endured the tearing pain from his body, and used his heart for two purposes, while running the Soul Devouring Technique, forcibly refining the magic power released by the Demon Heart Crystal, improving his own strength, and cultivating the Six Veins Shengang, forcibly refining the large amount of magic surging in the meridians into the bone marrow.

The pain of forging bones Ye Chenfeng has personally experienced and remembers it vividly, but compared to the pain caused by refining the marrow, the pain of forging bones is nothing at all.

As the magic power released by the Demon Heart Crystal was compressed into the bone marrow, Ye Chenfeng suddenly had a feeling like ten thousand arrows piercing his heart, and every point of magic power compressed into the bone marrow was like thousands of silver needles piercing into it, and he died in pain.

"Whew, bear with me, I must endure it. ”

Ye Chenfeng clenched his fists, gritted his teeth and persevered, enduring the inhuman pain brought by the refining of the marrow.

However, as more and more magic power was released by the Demon Heart Crystal, Ye Chenfeng's body slowly swelled, and tiny cracks spread on the surface of his skin, and a large amount of dark red blood seeped out uncontrollably.

At this time, Ye Chenfeng felt as if his body was about to explode, and the energy released wantonly continued to explode in his body, Rao is physical body was extremely powerful, and he couldn't bear it.

Soon, blood flowers burst on the surface of Ye Chenfeng's flesh, and a large amount of flesh and blood could not withstand the energy released by the Demon Heart Crystal, and it continued to explode, and his bloodline also cracked.

"Chaos Divine Tree, suppress it with all your might. ”

The reason why Ye Chenfeng dared to take the risk of putting the Demon Heart Crystal directly into his chest and devouring it was precisely because he relied on the Chaos Divine Wood in his body.

Seeing that Ye Chenfeng couldn't withstand the energy released by the Demon Heart Crystal, he decisively controlled the Chaos Divine Wood to suppress the energy released by the Demon Heart Crystal to relieve his pressure and pain.

After being suppressed by the Chaos Divine Tree, Ye Chenfeng's rapidly expanding body slowly returned to normal, and the pain in his body was also reduced a little.

At this time, Ye Chenfeng, who had refined one-fifth of the Demon Heart Crystal energy, had reached the level of overflowing soul power in his body, and the soul beast blood dragon had also been raised to the limit of his strength, and he could no longer continue to grow.

This accumulation has reached perfection, Ye Chenfeng did not hesitate any longer, and let the soul power in his body continue to improve, breaking through the bottleneck of the realm as a matter of course, reaching the sixth-level Heavenly Beast Immortal Realm.

With a breakthrough in the realm, Ye Chenfeng's body endurance has been greatly improved, and the broken meridians and flesh and blood are slowly healing under the nourishment of the greatly improved soul power.

"Demon Heart Crystal, refine the marrow with all your might!"

Breaking through to the sixth-level Heavenly Beast Immortal Realm, Ye Chenfeng knew that it would be impossible for him to make another breakthrough in a short period of time, impact the realm of the Xuan Beast Sect, and devote himself to refining the marrow.

As more and more of the demonic crystal energy was integrated into his bone marrow, a large amount of blood flowed out of his body, soaking through the dirt beneath him, and staining him into a bloody man.

"Finally the exchange of blood has begun. ”

Ye Chenfeng knew that if he wanted to refine the marrow, he first had to change his blood, and only by changing the blood in his body could he cultivate the marrow refining realm to Xiaocheng.

The exchange transfusion process is extremely ferocious, and the slightest carelessness may fall short, let alone be disturbed, otherwise it will be life-threatening.

At the same time, the Black Demon and the Snake Demon King searched all around the ancient tomb, but they didn't find Ye Chenfeng's whereabouts.

"Damn, let that Ye Chenfeng run away. "I didn't find Ye Chenfeng, and I hated the snake demon king's teeth.

Although it completely stabilized its physical injuries at this time, the loss of its burning demon pill could not be recovered for a while and a half, and in a few years, it could not recover from its peak at all.

"Such a big ancient tomb, there must be a heavy treasure, I think that Ye Chenfeng got the treasure, it is likely to be refined as soon as possible, we will search around carefully, maybe there will be unexpected gains." The black devil's eyes flashed with a fierce color, and he looked around at the yin qi and proposed.

"Good!"

The Snake Demon King nodded, and searched Ye Chenfeng's whereabouts while working with the Black Demon Carpet.

Time passed day by day, Ye Chenfeng relied on tenacity and perseverance, while enduring the inhuman pain and torture, he suppressed the energy released by the demon heart bone into the bone marrow, accelerating the speed of his blood exchange, and slowly qualitatively transforming his bone marrow.

"Click!"

After about five days, the old blood in Ye Chenfeng's body was almost gone, and when the bone marrow slowly changed to give birth to new blood, the surface of the demon heart bone, which was almost exhausted, suddenly cracked.

The wisp of dark red blood that was conceived in the deepest part of the demon heart bone flowed out and melted into Ye Chenfeng's body.

Suddenly, there was a ghost crying wolf cry in Ye Chenfeng's body, and the dark red blood seemed to have life, howling in Ye Chenfeng's body, destroying his body.

In the blink of an eye, Ye Chenfeng felt that his body was damaged by the energy released by the dark red blood, and the meridians that had just healed had not long been damaged, and his internal organs were damaged again, and he hurriedly controlled the Chaos Divine Wood to suppress it.

But at this moment, this life-like dark red blood poured into Ye Chenfeng's mind at an extremely fast speed, wanting to devour his brain and control his body.

"What the hell is this blood. ”

Sensing the intention of the dark red blood, Ye Chenfeng was shocked in his heart, and hurriedly controlled the God Devouring Brain to release a powerful devouring power to envelop it, forcibly erasing the mysterious consciousness in the blood.

"Woo ......"

Sensing the threat of the God-devouring brain, the dark red blood immediately became agitated, releasing blood light one after another, wanting to escape from Ye Chenfeng's mind.

But the God Devouring Brain completely restrained it and didn't give it a chance to get out of trouble, and one after another devouring power penetrated into the blood, quickly refining its consciousness.

Soon, consciousness in the dark red blood became weaker and weaker. In the end, it turned into a drop of blood containing pure soul power, floating in Ye Chenfeng's mind.

The next moment, the information of this drop of blood appeared in the god-devouring brain.

"Heavenly Soul Blood, the first-class soul blood between heaven and earth, contains the power of the Heavenly Soul, which can nourish the soul beast. ”

If it weren't for the God Devouring Brain, Ye Chenfeng would never know the Heavenly Soul Blood, because in the records of the Fighting Soul Continent, the Earth Soul Blood was only mentioned, and the appearance of the Earth Soul Blood that time alarmed many hidden old monsters in the Fighting Soul Continent, setting off a bloody storm.

Knowing the information of this mysterious blood, Ye Chenfeng was overjoyed, and without hesitation, he condensed the blood dragon in his mind and devoured the heavenly soul blood in one bite.

Devouring the blood of the Heavenly Soul, the blood dragon immediately transformed, the dragon scales covering the whole body became larger and larger, and the majestic dragon horns became sharper and sharper.

And on its forehead, there is a faint antique pattern of the word 'king'.

"Groan!"

Just when the blood dragon fused with the blood of the heavenly soul and underwent a qualitative change, a penetrating dragon groan sounded in Ye Chenfeng's mind, and the terrifying sound wave shattered the heavy formations, soaring straight into the sky, and the heavens and the earth throbbed.

"What a sound. ”

The Black Devil, who was struggling to search for Ye Chenfeng's whereabouts, heard the dragon's groan released by the blood dragon's transformation, and immediately cast his gaze to the northwest.

"The dragon groan, it's the dragon's groan, it's from the Ye Chenfeng soul beast, and he's in the northwest!"

Determining that the terrifying sound that was spreading between heaven and earth was the sound of a dragon's groan, the Black Devil and the Snake Demon King were overjoyed, and immediately accelerated over, preparing to join forces to kill Ye Chenfeng.
