The black energy poured into Mu Xuan's body, and then brutally passed through the blockage of the meridian flesh and blood, converging on the black bones, making the steel-like bones more and more dark.

The indescribable severe pain also impacted Mu Xuan's mind at this time, in the face of this severe pain, even with Mu Xuan's concentration, there was dizziness surging in his mind, but he pursed his mouth tightly and forced himself to be awake, he knew that once he was unconscious, those energies would burst his body and turn him into the pure energy wandering in this ancient dragon pool.

"Roar!"

The bright firelight was also at this time, from the courage on the surface of Mu Xuan's body, the firelight converged, and turned into a huge fire dragon light and shadow behind him, and with the color of the bones in Mu Xuan's body becoming deeper and deeper, the entrenched fire dragon behind him seemed to become more and more condensed, the cyan dragon scales flickered, lifelike, and a kind of substantial coercion was also quietly spreading at this time.

Time, in this dark ancient dragon pool, boring and slow passing, unconsciously, is ten days passed...

In the past ten days, Mu Xuan's body was in a state of convulsions all the time, and the severe pain even made his body slightly numb, and the green tendons on his skin were agitating, as if he was about to break out.

And behind him, the entrenched fire dragon is also clearly visible, and even, it is as if you can feel the hot breath of the dragon, this fire dragon is like a living thing.

At this time, if you go deep into Mu Xuan's body, you will find that the bones in his body are already pitch black to the extreme, but under that pitch blackness, there is an indestructible solidity and toughness.

At this time, Mu Xuan's skeleton was undoubtedly much stronger than before entering the Ancient Dragon Pool...

The things that the dragon clan is proud of are nothing more than two kinds, bloodline and body, bloodline aside, the foundation of the body is the support of bones, and now, Mu Xuan really has a body comparable to that of the dragon clan!

……

"Your current keel should have reached the strength of a high-grade keel, which is very good..."Xiao Gollum said at this time.

"A good keel... It's not enough. ”

Mu Xuan's eyes opened slightly, but in his black eyes, there was a fanatical ambition surging.

"You... Want a savage keel? Little Gollum was slightly startled and said in amazement.

"Since you have come to this ancient dragon pool, you naturally want the best thing!"

Mu Xuan smiled, and immediately his mind moved, and the pure light cluster suddenly spun at a high speed at this time, and a terrifying Heavenly Dao will power swept away, stirring this quiet ancient dragon pool into waves.

……

Time passed quietly.

And somewhere at the bottom of the ancient dragon pool, a figure was covered in a thick black viscous pool of water, which was like silt, and it was wrapped so tightly that only from the faint outline could there be a sign of a human form.

In the surroundings, the vast and endless black energy is pouring into it, but with the infusion of such energy, there is still no movement in the mud.

Laugh at.

I don't know how long the silence lasted, but at a certain moment, the mud trembled, and a pair of black eyes that shimmered brightly emerged from it.

"Ugh."

Mu Xuan, who opened his eyes, sighed softly in his heart at this time, now he should have been in this ancient dragon pool for more than half a month, but unfortunately, since the previous successful remodeling of the bones and the bones in his body turned into a high-grade dragon bone, no matter how Mu Xuan absorbed the energy in this ancient dragon pool, the dragon bone in his body was still at the top level, as for the so-called wild dragon bone, it was obviously still not reached.

"No wonder that barbarian dragon bone is so rare in this dragon clan..."Mu Xuan smiled bitterly, only then did he understand how difficult it was for the so-called barbarian dragon bone to appear, no wonder only characters such as the predecessors of the Blood Dragon Emperor could have it.

"I want to... I'm afraid this savage dragon bone is not something that can be possessed simply by absorbing the energy of the ancient dragon pool. When Mu Xuan was a little helpless about this, the sound of Xiao Gollum sounding at this time.

During this time, he had been paying attention to the changes in Mu Xuan's body, although Mu Xuan relied on the power of the will of the Four Domains Heavenly Dao to refine and absorb the energy in the ancient dragon pool in a whale swallowing way, but this did not change qualitatively except for making the black bones like steel in Mu Xuan's body more and more dark, obviously, this should not be caused by the lack of energy.

"Huh? What did you find? Mu Xuan also gradually calmed down, and immediately asked in his heart.

"You haven't used spiritual power here, maybe if you want to obtain that savage dragon bone, you not only need a powerful physical body as a carrier, but you may also need a strong spiritual sense to control it......"

Xiao Gollum's tone was a little puzzled, and after he speculated, he said softly, "Do you want to try it with mental power?"

Mu Xuan nodded, was silent for a long time, and suddenly gritted his teeth, his heart moved slightly, and there was a wisp of spiritual power pouring out of the sea of self-knowledge.

Creak!

However, just as that wisp of spiritual power was pouring out, the black pool of water that filled the surrounding area was surging, and a trace of black energy adhered to it, and a piercing sound came out.

Pain!

When that harsh voice came out, a sharp pain that was clearer than when the bones were broken before rushed into Mu Xuan's mind frantically, causing bloodshot in his pupils to immediately rise.

Mu Xuan's palms clenched, his nails even pinched into the flesh and blood of his palms, and the next moment, he took a deep breath, and a ruthless color swept through his eyes.

Rumble!

With Mu Xuan gritting his teeth fiercely, the surging spiritual power suddenly swept out of the sea of his knowledge like a tide.

Cuckoo!

When such a surging spiritual power gushed out, the surrounding pools of water seemed to be boiling, and they frantically adhered to the spiritual power one after another, as sharp as a blade, fiercely cutting Mu Xuan's majestic spiritual power.

The crazy pain also poured into Mu Xuan's mind at this time, and the indescribable pain made Mu Xuan's face with green tendons exposed.

In that kind of tidal surge of sharp pain, the dizziness in Mu Xuan's brain was also constantly accumulating, and he could sense with a little horror that his consciousness was gradually fading at this time.

The severe pain caused by this spiritual power was even more violent than the broken bones before, no wonder those who entered the dragon clan here were all guarding the sea of knowledge, and they didn't dare to let their spiritual power leak out at all.
