Ashen Dragon

Koschech roared hoarsely, swinging his battle axe in a wide arc, fiercely chopping towards the head of the Red Dragon. A powerful wind pressure erupted around, and a deep ominous light emerged on the axe blade.

Countless large, twisted demonic figures appeared in the sky, dragging at the legs of the Red Dragon and entangling his body, as if to swallow him into the abyss.

But in Cassius's claws, several large spell vortices appeared, bursting out with a powerful attraction, completely engulfing the abyssal power. At the same time, a faint purple light emerged on his body.

——This was his last ten-ring spell slot as a Legendary True Dragon Mage.

Eternal Freedom!

The Red Dragon suddenly spread his wings, soaring into the sky, transforming into a residual image trailing flames, breaking through the chaos fog's confinement, and leaping into the sky ten thousand meters high.

He didn't hesitate at all, directly swallowing Matalotok into the other-dimensional space inside his belly, determined not to let the Frost Giants have him.

"Swish——"

Koschech's battle axe swung in vain, cleaving open the space in front, creating a hundreds-of-meters-long abyssal fissure, from which tens of thousands of twisted, ugly demons roared noisily as they emerged.

His entire body was shrouded in thick black fog, breathing heavily, staring deadly at the Red Dragon in the sky, his eyes filled with anger and hatred.

"Reptile——"

"Boom!"

A flame resembling divine punishment descended from the sky, carrying an aura of total destruction, directly piercing through the body of the Tanari Frost Giant.

But soon, the fog from the abyss flowed into the wound, instantly transforming into writhing flesh that filled the scorched hole.

The Tanari Frost Giant was unharmed, only increasingly infuriated, his eyes ablaze with fury, his roar making all things tremble.

Koschech lunged again, but Cassius agilely sidestepped, evading him. Silver flames of order spurted from deep within his throat.

The Tanari Frost Giant was enveloped entirely by silver-white flames, emitting painful, frenzied howls within. His flesh was continuously burned, yet reborn time and again.

"Immortal essence..."

Cassius felt the demigod-level abyssal pressure, eyeing the giant, formidable body of the Tanari Frost Giant with a slight furrow of his brow.

"Matalotok can only suppress that divine power for a moment...

Even temporarily losing divine power, this Tanari Frost Giant still possesses demigod-level essence, impossible to kill by ordinary means, we can't delay any longer." He thought.

"Since we are in Avernus..." The Red Dragon manipulated the authority of Avernus within him, drawing a blazing longsword from the void: "Then let's use Hell's power to annihilate him!"

"Buzz——"

A force embodying Hell's Law spanned across the sky, controlling this plane. Endless Hellfire rose from the ground, flowing towards the Red Dragon in the sky.

Cassius transmitted to the Deep Prison Demon Refiner in the distance: "Piere, I need to borrow your strength. Only complete Hell's authority can slay a demigod-level Frost Giant!"

Piere's face instantly darkened, hidden anger in his tone: "That's impossible! I am the one recognized by Lord Asmodius as the Master of Avernus!"

Cassius dodged the Frost Giant's furious punch, continued communicating: "Piere, you must think clearly! If we don't kill Koschech now, when he regains his senses and recovers his divine power, all of Avernus will fall!"

"The foundation of the Ashen Empire is in the Prime Material Plane, even if the entire Hell is occupied by the Abyss, I'd only lose a few enclaves, it wouldn't hurt the core."

"But if Koschech conquers Avernus, you'll only once again become a stray dog! There will be no place for you to shelter in the entire Multiverse!" Cassius's tone was especially fierce.

Piere asked: "Then why not let me use the complete Hell authority to kill him?"

"You can't defeat him."

Piere gritted his teeth, his voice hoarse: "I don't trust you, Cassius, you're more greedy and shameless than us devils."

Cassius chuckled, again dodging the falling battle axe from the sky: "We can sign a pact, the Styx River is always the fairest, isn't it?"

"Boom!"

The frantic Koschech smashed the ground with his axe, causing the earth to tremble with a dull wail.

After a moment of silence, watching the extreme madness, devastating all Tanari Frost Giants, Piere felt a chill in his heart, finally said somewhat helplessly:

"Alright."

The pact was signed, the Deep Prison Demon Refiner reluctantly threw the Purgatory Longsword, letting Cassius catch it midair.

The powers of both authorities merged, emitting terrifying waves, causing raging Hellfire to sweep across the sky, burning everything, even Koschech emitted a painful wail.

A Purgatory Longsword, a thousand meters long, gradually emerged in the sky, radiating terrifying pressure. It was the embodiment of the supreme power of Avernus, every devil's dream.

"Look!"

"That power... resembles Zarriel from before!"

"Could that be the authority wielded by Hell's Lord? But——why does it appear in the claws of the Ashen Empire's Emperor?"

"Indeed, it should belong to Lord Baal!"

The devils looked at the Purgatory Longsword in the sky, immediately started discussing, these sly and cunning beings seemed to vaguely guess something, their gaze at Piere turned playful.

Perhaps, in this Avernus, there's not only Piere one to lean on.
