“{ULTIMATE PINNACLE}!!!”

A single point of black and white light compressed into perfect focus, piercing through the fabric of reality.

Even if only for a fraction of a second…

The resulting explosion was so devastating that even the Void Ruler present in this world turned her gaze toward it, feeling genuine threat.

Lucifer screamed in horror and agony. The sphere devoured his soul without mercy, eroding his very existence as the family released him upward.

Like a blazing meteor, he slammed into his benefactor—the one who had summoned him here—weaponized against his will.

“LUCIFER, WHAT DO YOU THINK YOU’RE—?!”

“HELP MEEEEEE!”

Before the Universal Computer could stop him, his soul struck her massive body across the gigantic portal she had torn open.

BOOOMMMM!!!

Lucifer’s soul vanished as he burned into nothingness. The rest of the Void Ruler’s body began exploding from the inside out, shedding colossal pieces with every blast.

“ERROR…! MY INTERNAL SYSTEMS…! HOW COULD THIS… BE?! LUCI… FER…! YOU DAMN USELESS… BASTARD…!”

BOOOM! BOOOM! BOOOM! BOOOM! BOOOM!

Her colossal artificial body could not stop exploding from within. The damage inflicted by Lucifer’s Soul Fragment—piercing her, then detonating inside—was catastrophic.

“A-AAAAAA-AAAAA—AAARRGGHH…!”

Her voice of agony echoed across the entire world of Bestia, glitching, mechanical, and horribly distorted.

Everyone watched the scene in awe.

From immortals and mortals to machines and martial beasts across the oceans—even the lazy, ancient constellation sleeping beneath the largest mountain in the world.

“Hoh~ They sure never stop amusing me, hahaha!”

As she laughed, Zero One’s group glanced into the skies and noticed the explosions rocking the world, making everything tremble nonstop.

“W-What happened?!” Wai Tian asked.

“S-Something red hit the Universal Computer…” Yin Sheng muttered.

“Something red?!” Zero Two asked. “I managed to take some pictures, but… What the hell is this? A soul? Someone screaming? It looks like a chimera made of ugly, twisted things!”

“Whatever that was, this is our opportunity, everyone!” Zero One cried. The immortals behind her, along with the millions of machines and her mother, looked at her with eyes full of determination. “This is the moment we stand together for this world… Both the original inhabitants and the invaders who want to redeem themselves…!”

Her voice echoed through every machine, and the immortals, with their enhanced senses, could hear her clearly.

“We can’t waste any more time!” she said. “Please, everyone… Would you lend me whatever strength you have left?! For this final push—to save this world! To save everyone…!”

The immortals, who still carried some doubt on their faces, stopped hesitating the moment they saw the two primordial beasts step forward.

Their auras, overflowing with power, surged toward Zero One, her sisters, and her Mother’s tree.

Suddenly, they were flooded with immense quantities of Heavenly Ki. Their systems powered up to the maximum and continued improving without pause.

“Of course! We’re in!” Wai Tian stepped forward. “We’re friends, after all, Zero One!”

“We’ve always been your friends, Zero One,” Yin Sheng said. “Did you even have to ask?”

“Yes, I’ll do whatever I can as well… All the time I’ve spent here has been precious to me,” Sara said. “I’ll give everything to help you, Zero One. You’ve taught me that no matter our origins, anyone can become a great person if they truly mean it.”

“KRIEEEEEH!” Violet roared.

“AWOOOO!” Snow howled.

“Piiikyuuuhh…” Shiro looked exhausted but still willing to help one last time.

“Of course, dear,” her mother said. “You don’t even need to ask… I believe what struck the Void Ruler was Lucifer’s soul. She had summoned him here briefly… He burned with such intensity that he resembled a meteor—or even a star. And I believe it was Anna and the others who launched him, amazingly enough.”

“S-So they’re still fighting…?”

“The Heavenly Demon…”

“And the Heavenly Empress!”

“Anna and Song!”

“Their adoptive daughter and their son…”

“If they did that, then… That means…”

The immortals, of all races, shapes, and sizes, looked at one another.

Long ago, they had been divided by appearances and customs.

Now, the world faced a cataclysm—an apocalypse unlike any other.

In the war to protect their home, they had been forced to set aside those differences, even after clinging to them for thousands of years.

To survive together and protect the world they loved, they had no choice but to unite.

Fishmen, Lions, Tigers, Birds, Wolves, Insects, Bears, and many more…

Back then, they had done it unwillingly.

But now, after learning to cooperate through countless hardships,

Their hearts were more united than ever.

“Let’s do it, everyone!”

The giant Lion Immortal was the first to roar.

He had also been the first to oppose the machines’ redemption, tearing them apart despite their pleas for forgiveness.

Afterward, guilt had settled in his heart—despite having slain the monsters that brought disaster to his world.

That guilt would not fade, and so…

He felt he had to be the first to speak.

“Yeah…”

“Let’s do it…”

“Whatever it is…”

“We need to save our world!”

“Yeah!”

“OOOOOOHHHH!!!”

They were not even that many—fewer than a hundred.

Yet these Immortals embodied the unyielding spirit of the animal people of Bestia,

The most peculiar and unique of all Murim Worlds.

“Everyone…”

Zero One began to cry as she witnessed their united hearts. Everyone stood with her.

This time, for sure…

They would make things different.

They would save the world they could not save before! 𝓯𝙧𝓮𝓮𝒘𝓮𝙗𝙣𝒐𝒗𝒆𝓵.𝓬𝓸𝒎

“Let’s do this, my daughters.”

Mother surged toward the skies. Her gigantic mechanical tree twisted and transformed, abandoning its roots as massive propulsors ignited. It soared toward the crack in space.

“Let’s go!”

Everyone rushed toward the massive mechanical tree as it ascended. Once inside, a colossal sphere of light glowed brightly, brimming with energy.

“Everyone, please pour your energies into this sphere! Not only that—your emotions, your memories, your techniques… everything that makes you who you are!”

This sphere had been designed by Mother—a “mechanical soul,” an artificial imitation created through her technology.

It was empty for now, but it could serve as a vessel for everyone’s power and manifest into something powerful enough to drive the Void Ruler away.

The immortals looked at one another and nodded without hesitation.

They pointed their hands toward the glowing, spiraling sphere and began pouring their energies…

As they did, they thought of those they had lost.

Their mothers.

Their fathers.

Their grandpas and grandmas.

Their children…

Their babies…

Their sons and daughters.

Grandsons and granddaughters.

Uncles and aunties.

They thought of their lives.

Their paths, their struggles.

Their hopes.

Their dreams.

And finally,

Their love.

Even the most vicious Demonic Cultivator closed his eyes and furrowed his brow.

He recalled when life was simpler, before he had fallen onto this dark path—when he still had something he loved.

He channeled those long-forgotten memories and emotions.

Even those with rotten hearts had once been innocent children.

These old, cherished memories of simpler, happier times flowed into the sphere.

FLUOSH!

The Artificial Soul absorbed everything, displaying countless images.

The laughter of children. The smiles of countless people.

Zero One, her sisters, and Mother finally saw it all.

They finally understood.

What made a world…

It was its people.

“How beautiful…”

Mother smiled through her tears as she witnessed everything.

“I see now… What makes this world so beautiful and unique… And perhaps what that monster seeks to steal for power…”

As Mother cried, her daughters moved to her side.

Zero One held her hand, while Zero Two and Zero Three smiled at her gently.

“Let’s do this, Mom!”

Raven nodded with a sweet smile.

Countless memories of Mother also appeared within the sphere.

Memories of her time with Raven. Every precious day she had cherished.

Her precious memories of her daughter…

“Yes… Raven, dear.”

RUMBLE!

Meanwhile, in the skies above Bestia, the monstrous Void Ruler screamed in endless agony. Her systems could not repair themselves fast enough. The damage Lucifer inflicted continued without end.

“I-I NEED…! I NEED TO DEVOUR THIS PLANET ALREADY…! ONCE I DO, I CAN RECOVER…! ONLY THIS DELICIOUS STORY—THE STORY OF A WORLD THAT HAS FACED SO MANY DIFFICULTIES AND PERSEVERED… THE PERFECT MEAL!”

Her tentacles, still burning with Lucifer’s Cosmic Soul Flames, rushed downward toward the planet’s crust.

With no one left to defend it as both sides ascended to confront her, she was finally free to consume it.

And yet…

“What do you think you’re doing?”
