On the colorful light egg, the cracks became denser and denser, and finally burst open in an instant after a crisp sound.

At this time, the colorful flames became more and more violent, like a colorful pillar of fire rising into the sky, and then, a pair of colorful crystal wings that could cover the mountains quickly stretched out from the monstrous colorful light.

Colorful lights and flames spread all over the sky, and through those colorful flames, Du Fei and the others could vaguely see that there was a huge shadow in the flames that was elegantly stretching out that huge body, this was the Nirvana rebirth of the ancient Heavenly Phoenix!

An extremely terrifying coercion also spread out madly at this moment, making the heavens and the earth tremble!

"That's the Ancient Heavenly Phoenix!"

Du Fei looked at the huge existence that stretched out its body gracefully with a shocked look, although he couldn't see what it looked like, but according to Du Fei's understanding of the Heavenly Phoenix Immortal Sutra, he had already guessed through the outline.

"This fluctuation—"

Guan Yan also stared at the huge body in front of her, and then her face became more and more ugly. At this moment, she completely understood, even with Du Fei's assistance, their trip would be considered scrapped, even if the housekeeper was here, it might not be able to match this kind of existence!

And they even want to kill such beings and take their demon crystals and essence blood!? This is really the biggest joke in the world.

"Let's—"

This time, Guan Yan no longer had any hesitation, but gritted her teeth violently, and then waved her hand vigorously, ready to leave regardless of it.

"Boom—"

However, just as the group was about to leave, above the sky, suddenly, there was a thick dark cloud rolling, the number of this dark cloud was at least ten times richer than when Du Fei had hit the peak martial arts realm of the fifth grade before, and in that dark cloud, the thunder snake swam uncertainly, as if the thunder in the sky had converged at this moment!

A devastating force began to coalesce in the clouds.

"It's... Tribulation God Thunder... Could it be that the Ancient Heavenly Phoenix's Nirvana once is equivalent to our human powerhouses crossing the Sect Tribulation once?" Du Fei stared at this scene, his pupils contracted slightly, and a look of horror flashed in his eyes! If this is really the case, then what level has the strength of this Ancient Heavenly Phoenix reached?

Guan Yan and the others also looked at this scene dumbfounded, such a big scene, but ordinary people can't see it at all!

"We, don't go!"

Looking at this scene, Du Fei hesitated for a moment before suddenly speaking softly.

"What do you say?" Guan Yan looked back at Du Fei in surprise and said.

Du Fei gritted his teeth, and after a while, he said slowly: "The extent of this Heavenly Tribulation God Thunder is not at all something we can imagine, with the state of this ancient Heavenly Phoenix, it may not be able to succeed in the tribulation. Moreover, if it succeeds, even if we run farther, it will not work, and if it fails, then our greatest chance will be!"

"Chance?" Guan Yan's eyes flashed a strange color, and then she nodded slightly, and then the group went around behind a boulder this time, and then cautiously looked at the scene ahead.

"Whoa—"

In the colorful light and colorful flames that filled the sky, at this moment, a clear groan suddenly sounded, and in this voice, there was a strong taste of provocation.

It seems that this ancient Heavenly Phoenix is challenging the Heavenly Tribulation God Thunder at this time!

"Boom—"

And that Heavenly Tribulation God Thunder seemed to have sensed the provocation of the Ancient Heavenly Phoenix, and in an instant, a rumbling low sound reverberated between heaven and earth, and under this kind of thunder, Du Fei and the others felt it extremely clearly. Heaven and earth trembled slightly at this moment, and looked at the boundless Heavenly Tribulation God Thunder Tribulation Cloud, as if the end of the world had come.

"Uhhh

In mid-air, the colorful light was magnificent, and then I saw a series of colorful pillars of fire instantly roaring towards the sky, like that, as if the ancient heavenly phoenix actually took the initiative to attack.

"Boom-"

The Heavenly Tribulation God Thunder seemed to let out a roar at this moment, and then greeted the seven-colored pillar of fire that rose into the sky, and one thunderbolt after another roared down in an instant.

"Boom, boom—"

The thunder and the seven-colored pillar of fire collided fiercely in the distant sky, and in an instant, the entire heaven and earth seemed to explode at this moment, and the loud sound caused the earth to tremble, and cracks continued to spread out on the ground.

Du Fei and the others all looked at the scene above the sky with shocked faces, where the colorful pillars of fire and thunder continued to wreak havoc.

Even Du Fei, a madman who takes the initiative to attack every time he crosses the sect tribulation, is stunned when he sees this scene, but Du Fei is not too shocked in his heart, he is just cultivating the Heavenly Phoenix Immortal Sutra, so he is almost not afraid of this Heavenly Tribulation Divine Thunder, not to mention this real ancient Heavenly Phoenix? But will things really be so easy?

The violent thunder, I don't know when it began to become more and more violent, from the beginning of the small, at this moment these thunder has turned into a series of thunder waterfalls, every time it pours down, the momentum is terrifying to the extreme! It is as if everything in front of it will be destroyed.

And those originally scattered pillars of colorful fire also condensed in an instant at this moment, just like the colorful ocean boiling at the same time, and rushed towards the thunder waterfall falling above the sky.

"Whoa—"

The crisp chirp sounded again, but this time there was a little more pain in the sound.

"Uhhh

In the next moment, all the wings of the ancient heavenly phoenix seemed to be vaguely extended, and then the colorful crystal feathers quickly converged together in an instant, carrying monstrous flames and slamming forward.

It seemed to sense that the ancient heavenly phoenix was also attacking with all its might, so the thunder waterfall pouring down from the sky was also quickly gathered together at this moment, directly forming a huge thunder vortex, the thunder vortex was spinning wildly, and in it, the infinite thunder continued to condense.

"Boom-"

After a while, this thunder condensed into an offensive together, directly turned into a sea of thunder, and it fell like this, directly covering it downward!

"Boom-"

And all the attacks of the Ancient Heavenly Phoenix also collided wildly at this moment, and then, the two extremely terrifying attacks collided together like this!

An indescribable fluctuation, almost in an instant, poured in all directions, Du Fei and the others almost subconsciously fell to the ground in an instant, at this moment, everyone was crazy to urge their own protection, trying not to get involved in such a situation, because, no matter what, as long as they are involved in this situation, then the end of the people present is only the same, that is, death!

Because, the collision of this kind of power is too terrifying, so terrifying that Du Fei and the others are not qualified to intervene at all.

"Whew-"

Suddenly, an extremely poignant sound suddenly sounded, and then, the huge figure in mid-air smashed directly into the huge crater at this moment, and the colorful flames and colorful light in the sky disappeared almost instantly at this moment.

Above the sky, the crazy and raging thunder seemed to emit a silent taunt at this moment, and then slowly dissipated.

"Knot... Is it over?" Guan Yan raised her head in amazement, looked at this scene and said.

"It seems that the Ancient Heavenly Phoenix Tribulation failed!" Du Fei also stood up at this moment, feeling the aftermath that was still left between heaven and earth at this moment, and said softly with a somewhat strange expression.

"How is it possible, that ancient Tianfeng is so strong, it really failed......" Guan Ting also stood up with a little hesitation and said.

"Now, it's not the time to think about this problem, but, since this ancient Tianfeng has failed...... Then, I'm afraid the next situation will be even more troublesome!" Du Fei frowned, and his eyes swept around.

Then I saw that at this moment, Zhou Qing, Lu Jiang, and Yang's two demons and three people appeared almost at the same time, and then everyone stared at the crater that had cracked most of it with a strange face, and then looked at the clouds that were quickly dispersed in the sky, and the expressions on everyone's faces were weird to the extreme.

"Actually... Failed!?Ancient Heavenly Phoenix crossed the Nirvana Tribulation, and actually failed!?"

"Hahahaha, I didn't expect him to fail! Good! Good!"

"God really help me! This ancient heavenly phoenix is destined to fall into my hands!"

All kinds of voices sounded almost at the same time, and then, almost in the next moment, everyone trembled, and then directly turned into streamers and rushed towards the crater, because everyone understood that at this moment, the ancient heavenly phoenix had already failed to cross the catastrophe! And at this moment, it was the weakest moment in its life, and if it wanted to get the ancient heavenly phoenix, so as to ascend to the sky in one step, this was already the best opportunity! If you miss it, there will be no chance in the future!

"Let's go too!"

Looking at this scene, Du Fei's complexion changed, and he said softly. Although the situation in front of him is still incomprehensible, since someone has already come forward to explore the way, if he doesn't go to see what the situation is, then Du Fei will not be willing to do it anyway!

"Uhhh

Hearing this, Guan Yan and the others also nodded slightly, and then in the next moment, everyone's soles of their feet were stepped on, and their bodies instantly turned into a streamer of light and rushed directly towards the crater.
