"evolution?!"

Mu Chen and others were stunned at this moment. They stared at the huge shadow in the black flames in the sky, and couldn't help but say, "Didn't it fail before?"

“So it wants to try again.”

Mu Feng also had some surprise in his eyes and said, "It seems that this Jiuyou Bird is extremely proud. The last time he failed to evolve, it took great pains to be able to be reborn in the fire again. Unexpectedly, as soon as he appeared, he planned to try to evolve."

Mu Chen was also shocked by the courage of the Nine Nether Bird. If ordinary people fail in a certain place, their psychological side will inevitably avoid it, but the Nine Nether Bird must get up from the place where it failed. This courage and arrogance are amazing.

“So can it succeed?”

Mu Chen asked in a low voice, and he looked up at the black thunder clouds spreading above the sky. The black thunder in it was like a huge black dragon squirming, exuding an indescribable power of heaven and earth.

"I don't know... Jiuyou Bird is an extremely powerful existence, and he has the eleventh ranking on the Ten Thousand Beast Records. If it can evolve successfully, it will be qualified to attack the Ten Thousand Beast Records Heavenly List. At that time... it will truly become a divine beast." Mu Feng said.

"Divine Beast..."

Mu Chen couldn't help but pursed his lips. This simple word gave people an unparalleled pressure, because in this vast world, every divine beast is a super existence. Facing these alien overlords in the world, even those supremely-level existences are afraid of it.

"But... this black god thunder tribulation is not that easy to overcome." Mu Feng also stared at the huge shadow in the black flames in the sky and said softly, there are so many spiritual beasts between heaven and earth, but how many people can finally get into that super level?

The simple word between the spirit beast and the divine beast is a gap that cannot be crossed by even the most arduous practice of the world.

"It has failed once before. Generally speaking, if anyone who fails to pass the tribulation, the tribulation will be destroyed in the thunder tribulation, but the Nine Nether Birds have escaped their fate before. If they fail this time, they may not have such good luck."

Mu Feng's original retreat gradually slowed down. Since the Jiuyou Bird was about to overcome the tribulation, they were safe. In the eyes of Jiuyou Bird at this time, they were like ants and were not worthy of their attention.

Mu Chen was also a little regretful when he heard this. If the Nine Nether Birds disappeared in the thunder tribulation, then no one would be able to obtain the spirit of the spirit beast. In this way, their Muyu would have no gains in this trip.

However, even if he obtained the spirit of the Nine Nether Bird Spirit Beast, who can refine it? I don’t know how lucky it was when Mu Feng was able to refine the Flame Dragon Eagle, let alone the Jiuyou Bird, which is more powerful and terrifying than the Flame Dragon Eagle?

When Mu Chen and his friends looked at the sky with some amazement and regret, a clear sound of sound resounded through the black flames that filled the sky again. This time, in the clear sound, there seemed to be a strong fighting spirit and indomitable desire.

It is challenging the Black God Thunder Tribulation in the sky!

"Boom!"

The black god thunder cloud seemed to have noticed the provocation of Jiuyou Bird, and the low sound that immediately echoed between the heaven and the earth. Under the thunder, Mu Chen and the others felt that the spiritual energy in the heaven and the earth was trembling, as if they were afraid of the terrible power of heaven.

"Cry!"

The clear sound resounded again, and in the dark flames, the giant wings of the Nine Nether Bird hidden in it blew up, and the black flames suddenly surged over the sky, turning into countless black pillars of fire, rushing straight up, and rushing towards the black thunder clouds.

Facing the Black God Thunder Tribulation, the Nine Nether Bird dared to attack on his own initiative.

boom!

The black thunder clouds quietly surged, and the black thunder was like a winding black dragon, looking indifferently at the whistling black pillars of fire all over the sky. Then the black thunder, containing the power of destruction, rushed down suddenly.

Bang bang bang bang!

The black thunder and the black pillar of fire were together fiercely on the distant sky. Suddenly, the whole world seemed to explode at this time. The loud rumbling sound made the earthquake tremble violently, and cracks spread out from the black basin.

Mu Chen and the others were all shocked at the terrifying formation in the sky, where black fire and black thunder were raging wildly.

The black thunder was obviously an extremely terrifying thing. The thunder descended in a posture of destroying all things in the world, shattering all the black pillars of fire.

The black thunder shattered the pillar of fire, and with a more terrifying momentum, it shot hard into the black sea of ​​fire that filled the sky, and finally shot the behemoth hidden in the sea of ​​fire.

Trepidation!

This time, there was a little more pain in the sound, but then anger appeared again in the sound. The nine netherworld birds sang together, and the black sea of ​​fire swept wildly, and finally turned into a black flame storm that almost connected the sky and the earth.

Buzz!

The earth began to crack in the rotation of the black flame storm, but fortunately, the main target of the Jiuyou Bird was the Black God Thunder Tribulation. As soon as the black flame storm took shape, it swept wildly towards the black thunder clouds.

Faced with the crazy attack of Jiuyou Bird, the black god thunder cloud also quickly squirmed. I saw that in the center of the thunder cloud, a vortex filled with black thunder light suddenly appeared. In the vortex, countless black thunders were gathering.

boom!

In the vortex, countless black thunders condensed together and finally turned into an extremely huge thunder pillar, rushing out with a bang, directly bombarding the black flame storm.

call out!

The black thunder pillar was like the punishment of the Thunder God, tearing the black flame storm apart, and the whole world seemed to be dimming at this time.

The Black Flame Storm, which had condensed Jiuyou Bird's full strength, was blocked again, and the Jiuyou Bird also burst out with extremely angry chirping. This damn thunder tribulation has stopped it once, so should I stop it again?

It is proud of it and is absolutely unwilling to admit failure!

The black flames in the sky suddenly shrank strangely. In that scene, it seemed that all the black flames had penetrated into the huge body of the Jiuyou Bird at this time.

As the black flame contracted, the huge body of the Jiuyou Bird finally appeared clearly in everyone's gaze.

It was a huge creature nearly ten thousand feet long. Its wings spread out to cover the mountains. On its body, the black feathers were deep and mysterious. A trace of black flames surged in the feathers. At its tail, the slender tail wings extended gracefully. At the end of the tail wing, clusters of black flames were slowly burning.

Although the Jiuyou Bird is extremely large in shape, it does not appear to be bloated at all. Instead, it looks elegant and slender, mysterious and beautiful, and fascinating.

However, at this time, the nine Nether Bird's pupils showed a fiery red color, full of unwilling anger. It stared at the thunder clouds entrenched in the sky, and then its wings fluttered. The wind suddenly rose between the sky and the earth, and black flames filled its huge wings, and it turned into a black flame, flapping its wings and flying high, and finally mixed with all its power, rushing towards the black thunder cloud.

It will fight the Black God Thunder Cloud in the final battle!

Mu Chen looked at the Jiuyou Bird, who was swaying his wings and rushed towards the terrifying black thunder clouds in a manner like a moth to the flames, and his heart was filled with shock.

Even the bystanders, who were so strong and unyielding, were amazed by the strong and unyielding nature of the Jiuyou Que.

However, in addition to the amazement, some regret arose, because Mu Chen saw that the black god thunder cloud shrank violently again. At this moment, it seemed that all the thunder in it was gathered together at this time.

That blow will inevitably shock the earth.

Boom!

The world became silent at this time, only the thunder resounded, and a black thunder that was almost the same as the body of the Jiuyou Bird, was like a hideous and angry black dragon, penetrated the heaven and earth, and finally bombarded heavily on the body of the Jiuyou Bird head-on.
