The black sound waves, like gentle ripples, spread out from this black basin, and where the sound waves passed, all the spirit beasts instantly turned into white bones, and on that white bone, not even a single trace of blood existed.

Mu Chen and the others all looked at the scene in front of them dumbfounded, and then their hearts fluttered, this scene was really too weird.

Woohoo.

Those spirit beasts turned into white bones, but there were majestic rays of light pouring out of their bodies, and finally turned into ten thousand rainbows of light, roaring across the sky, rushing towards the mysterious black eggs above the crater.

Airplanes.

And in the face of these rainbows containing majestic spiritual power, the mysterious black eggs also bloomed with black light, and then like a bottomless pit, they devoured all those rainbows.

Rainbows of light continued to rise from the bodies of those spirit beasts, and under the splendor, it was all their vitality.

And the most terrifying thing is that these spirit beasts watched this terrifying scene appear, but they were not frightened in the slightest, and there was some fanaticism in the scarlet pupils, and that feeling was like this moth to a fire, which made them feel extremely honored.

This strange contrast made Mu Chen's heart cold, and then he glanced at the mysterious black egg in the sky that was constantly absorbing the rainbow of Dao Dao, this kind of means far surpassed the wisdom that Mu Chen had seen in the past, and even, compared to humans, it was particularly cunning and ruthless.

"That black egg, it should be the Nine Shadow Sparrows..."Mu Feng's face was solemn, and he glanced at the black egg in the sky that absorbed many rainbows of light with fear.

"This spirit beast of the Black Abyss seems to be providing a lot of spiritual power to those Nine Phantom Sparrows..."Mu Chen said softly.

Mu Feng also nodded, and said: "And similar scenes, I'm afraid it's not the first time that this kind of scene has appeared, over the years, in this black abyss, there may be countless spirit beasts turned into white bones here, and all the spiritual power has been provided to the nine phantom sparrows." ”

"This spirit beast of the Black Abyss..."Mu Feng's face was a little strange, and he said: "It's like the Nine Phantom Sparrows are in captivity, let them grow, and after they are a little fat, they will slaughter them and extract spiritual power." ”

Duan Wei and the others on the side shuddered when they heard this, they would not be too surprised if it was a human being who did such a thing, but the layout of all this was just a spirit beast, although this spirit beast was quite powerful.

"And... Perhaps, the kind of copper piece we have obtained is also intentional, it uses it to attract some greedy human beings, and then take away the spiritual power in our bodies. Mu Feng smiled bitterly and said, "This time, maybe it's just that we people don't take it seriously, otherwise, I don't feel like our fate will be better than those spirit beasts." ”

Zhou Ye's face was also a little pale, if all this was designed by the Nine Shadow Sparrows, it would be too terrifying...

Mu Chen also sighed, he knew that most of what his father said was true, thinking that in these years, because of greed and temptation, there should not be a few humans who finally came here but could never go out, just like the skeleton he met in the black abyss, the skeleton was lucky before his death, escaped, but finally died because of his injuries.

"Then what now?" Duan Wei wiped the cold sweat from their foreheads, it was the first time they had encountered such a terrifying spirit beast, this kind of terrifying was not only strength, but also the kind of cunning and ruthlessness that was even greater than that of humans.

"Retreat!"

In Mu Feng's voice, there was no longer the slightest hesitation: "Don't think about it, in the Northern Spirit Realm, no one has been able to subdue this kind of existence, while its attention is now on those spirit beasts, we will retreat immediately!"

"Yes!"

Duan Wei and the others were also relieved when they heard this, in this strange situation, there was no hope at all, and it was a wise decision to leave as soon as possible.

Mu Feng obviously made up his mind not to covet the Nine Sparrows anymore, and after giving the order, with a wave of his big hand, a wave of people quietly swept up the mountain rock, cautiously facing the outside of the black basin.

"Big brother, the people of the Pastoral Domain are about to retreat!" The movement on their side was also noticed by Liu Yu, and Liu Yu hurriedly said.

"Leave them alone!" Liu Qingtian said coldly: "This situation is not right, we should rest assured when they leave, so as not to be wary of them." ”

"Then we..."Liu Yu hesitated, in fact, he was also made furious by the scene in front of him, that mysterious black egg was too weird, and his intuition told them that it was wise to leave far away.

"Wait!"

Liu Qingtian's eyes obviously flashed with a hint of struggle, but in the end, he gritted his teeth and said, the temptation of the Nine Shadow Sparrow is too great, if he can get it, even if it is only a small chance, but once he obtains it, he will become the master of this Northern Spirit Realm!

Liu Yu and Liu Zong glanced at each other and nodded, they had been preparing for this plan for so long, if they left like this, they were indeed a little unwilling.

When the people and horses of the Pastoral Domain quietly retreated, and the people and horses of the Willow Domain still did not give up, in the black basin, thousands of spirit beasts were also all turned into white bones under the diffusion of that black sound wave.

Call.

In the sky, countless rainbow lights roared, and finally all of them were sucked into the suspended mysterious black egg, and when the last rainbow disappeared, this piece of heaven and earth seemed to become unusually quiet at this time.

Click.

In the silence, there was a sudden sound of a slight cracking, this sound was not loud, but it made the people and horses of the Deliu Domain and the retreating people and horses of the Pastoral Domain like a lightning strike, and then their eyes looked at the mysterious black egg with some horror, only to see that on the surface of the black egg, there were subtle cracks.

Cracks appeared, black flames poured out one after another, and finally wrapped the mysterious black egg in it, and the strange black flames rose, and the spiritual power of the heavens and the earth seemed to be some signs of boiling.

"That's..."The cold sweat on Mu Feng's forehead slowly slid down his face, and his voice became hoarse: "The Nine Phantom Sparrow seems to be coming out." ”

Phew!

And just as his words fell, a clear sound that resounded through the heavens and the earth suddenly spread out from the black egg, and the black flames swept away like a storm, filling the sky.

On the black light egg, the cracks became denser and denser, and finally burst open in a crisp sound.

The black flames became more and more violent, and then Mu Chen and the others were a little shocked to see that a black winged wing that seemed to be able to cover the mountains stretched out from the monstrous black flames.

The black flames were burning in the sky, and Mu Chen's eyes could vaguely see through those black flames, in the monstrous flames, a huge shadow was elegantly stretching its huge body, and that scene was like an immortal bird born from the karmic fire.

A terrifying spiritual power coercion also diffused at this time, making the spiritual energy between heaven and earth boil.

"Is that the Nine Sparrows?"

Mu Chen looked at the behemoth that stretched its body gracefully in the monstrous black flame, although he couldn't see its appearance clearly, but the vague outline was already amazing.

"This fluctuation..."

Mu Feng also stared at the vaguely huge body, and immediately swallowed a mouthful of saliva, this level of spiritual power coercion, I'm afraid that even some strong people who have advanced to the three-day realm can't match it!

It is a great wonder that they even want to submit this kind of existence.

"Let's go!"

Mu Feng took a deep breath, completely restrained the salivation in his heart, and let out a low snort, ready to evacuate regardless of it.

Thundered!

However, just as Mu Feng was urging the people to retreat, above the sky, there was a sudden sound of thunder, they looked up, and they were stunned for a moment, only to see that above the black flames in the sky, there were suddenly black thunderclouds converging, and in the black clouds, there were faint thunderbolts like black dragons, surging quietly.

A devastating power emanated from the black thunderclouds.

"It's... Black God Thundercloud?"

Mu Feng looked at the black thundercloud, his pupils instantly constricted, and he suppressed a terrifying voice, which couldn't help but come out of his mouth.

"Black God Thundercloud?" Mu Chen was stunned.

Mu Feng took a deep breath, suppressed the shock in his heart, and muttered, "These Nine Phantom Sparrows... It's still trying to evolve!"
