The huge body of the Ancient Demon Snake moved rapidly on the plain, and under the scales, a surging black air flow once again gushed out, but this time it did not disperse, but condensed into an Ancient Demon Snake of the same size above the body of the Ancient Demon Snake.

The aura of terrifying energy caused the space around the Demon Serpent's phantom body to gurgle, as if overwhelmed.

"The attack of this primeval demon snake is not at all like the strength that Xianyi and five small steps should have, this attack is no worse than the second layer of Sendai!"

Yang Yu solemnly looked at the phantom of the demon snake in the sky, and on the Great Wilderness Dragon Pattern Sword in his hand, the thunder flashed.

"Great Wilderness Dragon Breaking Sword - Thor!"

Stepping into the void, Yang Yu's body quickly swept out, and the brilliant thunder on the Great Wilderness Dragon Pattern Sword was surging, condensing a thunder divine light exuding terrifying energy on the Great Wilderness Dragon Pattern Sword.

"Shhh

The Ancient Demon Snake Snake was swallowed, and the light flashed in his eyes, and the Demon Snake Phantom above the Ancient Demon Snake swept out, and its huge body slammed towards Yang Yu.

"Kill!"

Yang Yu let out a low snort, and the thunder divine light above the tip of the Great Wilderness Dragon Pattern Sword bombarded the Demon Snake Phantom.

Rumble!

Thundered!

The two collided, and in an instant, the heavens and the earth seemed to stand still for a moment, and the Thunder Divine Light and the Demon Snake Phantom collided together.

After a moment's pause, a huge explosion sounded, and the huge energy ripples that enveloped the entire sky swept through like a tsunami, constantly obscuring the sky above Yang Yu's head.

"Bang!"

With a roar, Yang Yu's body was bombarded on the ground by a huge energy impact from the sky.

"It's special......"

Yang Yu frowned and stood up from the ground, patted the dust on his body, and looked at the demon snake phantom in the sky that had turned into energy quite solemnly.

"I can only use the ultimate!"

Yang Yu watched as his figure shrank again, and his realm fell to the primeval demon snake that had reached one or four small steps of immortals, and a trace of killing intent flashed in his eyes.

"Thor!"

The primordial runes of the Thunder Emperor Treasure Technique in the palm of his hand shone brightly, and suddenly, a cold cry that went straight into his heart made the Ancient Demon Snake look in the direction of Yang Yu in horror.

"Boom!"

Countless thunderbolts fell from the sky, all of which bombarded Yang Yu's body, and then under Yang Yu's operation, they turned into black brilliant thunder gushing out of Yang Yu's body and surrounding Yang Yu's body.

As time passed, there were more and more thunderbolts around Yang Yu's body, and the number of them reached a level similar to the size of the Ancient Demon Snake!

"Fury!"

There was another angry shout that resounded through the heavens and the earth, and the black divine thunder around Yang Yu's body instantly condensed into a huge human form, and the terrifying aura filled the heavens and the earth!

"I am the Thunder Emperor, and Wan Lei surrenders!"

At the moment when the primeval demon snake was shrouded in the terrifying aura of the thunder giant, the thunder giant came to the primeval demon snake in an instant.

The terrifying thunder fist that made the space tremble with a terrifying aura directly bombarded the body of the primeval demon snake.

Boom! Boom! Boom!

The moment the Ancient Demon Snake was attacked, its body instantly swelled, and the outer skin of the Ancient Demon Snake on its body fell apart under the impact of black divine thunder, and pieces of black scales shot out in all directions from the outer skin.

"Boom!"

With a final roar, the primeval demon snake's outer skin vanished, leaving behind only a huge cloud of energy, suspended in the sky.

??“ ......"

A burst of thunder flashed, and the thunder and lightning giant condensed by Yang Yu turned into thunder and lightning and escaped on the plain.

And Yang Yu's body also stepped out from the wisps of thunder at this time, his long hair flowing, his white robe agitated, and his indescribable demeanor.

It's like a real young thunder god, descending into the mortal world to inspect everything!

"Now let's see how much this energy can do me!"

Yang Yu stepped forward, stepping into the void to the energy mass left by the Ancient Demon Snake, and the corners of his mouth raised.

"Go!"

Yang Yu's hands were sealed, and a shielding aura formation flew out, obscuring the energy mass left by Yang Yu and the primeval demon snake.

"Now let me see how useful you really are!"

Yang Yu's body slowly landed on the ground, sitting cross-legged, and wisps of brilliant devouring power directly erupted from his body, surging towards this ball of pure energy.

Whoa!

Hundreds of swallowing invisible silk threads flew out, enveloping the energy mass left behind by the primeval demon snake.

"Here we go. ”

With a low snort, above the powerful devouring power, powerful absorption fluctuations appeared, and the energy above the energy cluster all surged into Yang Yu's body under this powerful absorption speed, and all the pure energy began to emerge Yang Yu's vertebrae dragon!

"Refining!"

In Yang Yu's body, the true dragon blood in the vertebrae revived again, surging in Yang Yu's body, and all the pure energy in the energy mass left by the primeval demon snake was frantically swallowed into the vertebrae dragon.

Yang Yu's realm began to improve steadily, the speed was not fast, but it was very stable, and at this moment, the energy mass above Yang Yu's head was absorbed by Yang Yu, and began to shrink rapidly.

Soon, just an hour later, Yang Yu's consumption just now had all recovered, and as the pure energy within the Spine Dragon became more and more huge, Yang Yu's realm also began to improve rapidly.

Two hours later, half of the energy mass left by the Ancient Demon Snake had disappeared, and the realm in Yang Yu's body had also become extremely strong at this moment, and the eighth transformation of the dragon had reached perfection!

But all this did not stop, because Yang Yu still had more than half of the pure energy that had not been absorbed, and the energy mass floating above Yang Yu's head at this moment was still not small.

After absorbing it all, it was time for Yang Yu to break through the ninth transformation of the dragon!

"Boom!"

On the black plain, Yang Yu, who was dressed in a white robe, suddenly burst out with a strong aura, stirring up bursts of smoke and dust around him.

And the energy mass above Yang Yu's head had disappeared, and the powerful devouring power in Yang Yu's body had also dissipated, and the true dragon within the vertebrae dragon had also hibernated, sinking into Yang Yu's vertebrae.

Yang Yu, who had absorbed all the pure energy, did not unexpectedly break through to the ninth transformation of the dragon, but it was only a breakthrough, and it was still a long way from breaking through the Sendai realm, and there was a considerable distance.

"The ninth transformation of the dragon is special, and the energy of devouring a special primeval creature of this kind will break through a realm, if this plain is swept around, even if it breaks through to the Sendai realm, it is not impossible......

Yang Yu looked at the barren black plain, his eyes flickering.

"Let's go, find Xiao Lin'er first, and then see if there are any such primeval creatures in this plain, the energy contained in these primeval creatures is simply a treasure!"

Yang Yu looked at the endless black plain, his eyes flashing with brilliant light.

If he can break through the Sendai Secret Realm before going out, then Yang Yu will no longer be afraid of the major holy lands at all!
