686: Chapter Two Emperors Join Forces, Changes Occur Suddenly

Dragon Xuanyuan roared, and the illusory dark-gold Dragon seemed to have received a summons, pouncing towards the Grey Phantom Moth Emperor with a world-destroying Aura.

At the same time, Bai Yuan also unleashed his ultimate skill.

"Heavenly Slaughter Slash!"

Along with his angry roar, the longsword in his hand suddenly swung, and a dark-red sword light shot out like lightning.

Wherever this sword light passed, the surrounding space seemed to be torn apart, instantly dyed with a layer of dark-red light.

Immediately after, the Vicious Beast behind him suddenly underwent an astonishing transformation.

Its previously somewhat blurry figure, at this moment, seemed to be awakened, suddenly expanding.

Its body grew larger and larger, as if nourished by some powerful force, and fully revealed itself.

The appearance of this Vicious Beast resembled a tiger, with a body several zhang tall, like a moving small mountain.

Its wings spread out, covering the sky and sun, and the dark-red feathers on its wings shimmered with an eerie light under the sun.

Its entire body was covered in dark-red fur, like burning flames, making it look exceptionally ferocious and terrifying.

As soon as this Vicious Beast appeared, the surrounding blood color immediately became more intense, as if the entire world was dyed crimson.

However, although this Vicious Beast's appearance resembled Qiongqi from myths and legends, in reality, it was merely a combat auxiliary conjured by the user through some special means.

What it contained was still the user's own consciousness and power.

The purpose of doing this was nothing more than to first intimidate the opponent and create psychological pressure for them.

Just then, the two powerful attacks almost simultaneously hit the Grey Phantom Moth Emperor.

In an instant, there was an earth-shattering roar, deafening rumbles and dazzling lights intertwined, forming a huge energy shockwave that swept in all directions.

The core area of the swarm seemed to be torn apart by this force, and the surrounding space became distorted.

Under the impact of this force, the Grey Phantom Moth Emperor's body trembled violently, and its light gradually dimmed, but its eyes still flickered with an unyielding light.

It knew that this battle could not be avoided, and it had to fight until the very last moment.

The dust and light gradually dispersed, revealing the scene at the center.

To their astonishment, the Grey Phantom Moth Emperor was not severely wounded as expected, but instead floated in mid-air in an incredible posture.

Twisted light surrounded its body, as if it had just been Rebirth from a fierce explosion.

Although its wings were slightly damaged, the madness and determination in its eyes burned even more fiercely, as if the previous attack had only stimulated deeper potential and fighting spirit within its body.

"Hmph, a mere ant-like power, yet you dare to shake my prestige?"

The Grey Phantom Moth Emperor's voice echoed in the distorted space, carrying a hint of mockery and disdain.

Bai Yuan and Dragon Xuanyuan exchanged glances, both seeing solemnity and surprise in each other's eyes.

"We can't delay any longer, we must finish this quickly!"

Bai Yuan said in a deep voice, then spiritual power surged within him, and a denser killing intent condensed on his longsword, preparing to launch an even fiercer attack.

Dragon Xuanyuan was also the same; the dark-gold Dragon phantom behind him became even more solid, as if it could break free and materialize at any moment.

He took a deep breath, gathering all his strength into his claws, preparing to unleash an ultimate skill capable of changing the tide of battle.

Just then, the Grey Phantom Moth Emperor suddenly let out a sharp shriek, and immediately after, its body began to undergo drastic changes.

Its original grayish-black lepidopteran exoskeleton began to shed, revealing new armor shining with a strange light beneath.

And its wings instantly became crystal clear, each flap accompanied by a slight tremor in space.

"This is... metamorphosis?"

Dragon Xuanyuan exclaimed, he hadn't expected the Grey Phantom Moth Emperor to choose metamorphosis at this critical life-or-death moment.

Bai Yuan's face was grim; he knew that once the Grey Phantom Moth Emperor completed its metamorphosis, they would be in danger.

Thus, he no longer hesitated, his spiritual power boiling to its limit, his longsword cut through the air, carrying an Aura that could tear everything apart, pointing directly at the Grey Phantom Moth Emperor's vital point.

Dragon Xuanyuan also went all out, the dark-gold Dragon phantom transforming into a stream of light, arriving almost simultaneously with Bai Yuan's attack.

At the point where the two converged, space seemed to be completely torn apart, forming a terrifying black hole that devoured everything around it.

This black hole spread rapidly, instantly engulfing the spot where the Grey Phantom Moth Emperor had just been!

"Did we succeed?"

Both of them were panting, staring intently ahead; even they couldn't continuously unleash such attacks!

However, reality is always contrary to expectations; an unprecedentedly powerful Aura suddenly erupted.

"Cough cough cough, I finally succeeded, you all must die!"

The next moment, a grayish-black figure forcefully tore open the black hole and then stumbled out from it.

"This is beyond the Emperor Realm?!"

Bai Yuan and Dragon Xuanyuan perceived that this Aura had surpassed the Emperor Realm, very likely reaching the Realm beyond the Emperor Realm!

At once, both their hearts sank to the bottom; such an existence alone was a disaster that could destroy a nation!

But facing this sudden change, Bai Yuan and Dragon Xuanyuan's expressions remained unchanged; they exchanged glances and chose to continue fighting.

Just as the Grey Phantom Moth Emperor was about to make a move, its expression suddenly changed drastically.

Its originally ferocious face became even more distorted, and at the same time, its body began to tremble violently, as if enduring immense pain.

With several crisp "crack" sounds, fine cracks actually began to appear on the surface of the Grey Phantom Moth Emperor's body.

These cracks spread rapidly like a spider web, covering its entire body in the blink of an eye.

"Black Demon, White Demon, how dare you betray..."

The Grey Phantom Moth Emperor let out a mournful shriek, its voice filled with despair and resentment.

Feeling the changes in its body, he obviously realized something.

But this sudden turn of events did not make it completely lose its mind.

Despite being severely wounded, the Grey Phantom Moth Emperor still used its last shred of strength to fiercely release a powerful Divine Soul fluctuation.

This Divine Soul fluctuation, like surging waves, swept towards Bai Yuan and Dragon Xuanyuan at an astonishing speed.

This Divine Soul fluctuation was exceptionally fierce, as if it had a life of its own, tightly entangling Bai Yuan and Dragon Xuanyuan, like a persistent disease that was difficult to shake off.

Wherever it passed, the air was torn and eroded, emitting bursts of piercing screams.

Facing such terrifying Divine Soul fluctuations, Bai Yuan and Dragon Xuanyuan did not panic.

They clearly had anticipated this; both of them quickly deployed their respective defensive measures.

A layer of pale golden shield appeared in front of them, firmly blocking that destructive force.

However, the power of the Grey Phantom Moth Emperor's attack was too immense; even with Bai Yuan and Dragon Xuanyuan resisting with all their might, the shield trembled continuously, seemingly on the verge of shattering at any moment.

"Even if I die, I will make you pay the price!"
