Epic of Caterpillar

FLUOOOSH!

Suddenly, the portal where the Necrotic Plane Ruler was coming out from to attack the Supreme Gods disappeared, as they all heard a sudden scream coming from Hel's castle.

"Huh?! He's gone?" Flora wondered, looking around in confusion. "It is as if he simply and completely disappeared! What is going on?"

"Well, we were beating his ass anyways." Aura smiled cockily. "Now, I do wonder if Hel's been taken care of."

"It would be better if we go regroup with everyone else." The System Master said. "I can sense their presence in the skies, they're being carried by a huge Skeleton Dragon Maxima Summon."

"Is the fight finally over then?" Flora wondered. "Hahh… It ended much faster than I imagined, yet at the same time, it felt like an eternity…"

Meanwhile, Rimuru, Brontes, Nesiphae, and Wagyu and the other Wolves, also noticed the changes that had happened. The entire Realm suddenly stopped attacking them, and the portals which brought millions of Undead also closed.

"T-The entire realm has finally calmed down a bit!" Said Rimuru, sighing in relief.

"Yeah, more or less." Brontes said. "And the portals are finally closed… I-Is it finally over?"

"It wouldn't be good to lower our guards yet…" Nesiphae said.

"This stillness… Is certainly concerning- Ah! Look, everyone's coming!" Wagyu pointed at the sky as the group of Supreme Gods finally arrived, alongside Zehe's group, who descended from the skies using a Skeleton Dragon.

"ZEHEEE!" Rimuru quickly hugged Zehe. "You're back! A-And Everyone else too- Eh?! Where's Herbell? Oh, is that Hel?!"

"Herbell… He… He was killed by the Necrotic Plane Ruler." Zehe sighed. "He gave me his strength before… disappearing."

"Z-Zehe…" Rimuru felt shocked.

"N-No way…" Brontes muttered.

"That old skeleton…" Nesiphae sighed.

"…" Wagyu and the other wolves remained in silence.

"It seems we all had our hard battles." Flora sighed, arriving. "However, it looks like things have gone still. "I'm sorry for not being able to arrive in time. When we were about to do so, we were interrupted by that monster that appeared out of a portal."

"I wish we could had been of more help." Aura sighed. "I feel like we've been only disappointing you all this entire time…"

"Well, it is good that mostly everyone is alive anyways… And that girl, are you truly going to not kill her after what she has done?" The System Master pointed at Hel, who was being carried on Loki's arms.

"She's my daughter… She might had committed a lot of terrible things but… I just can't let you kill her…" Sighed Loki. "It is my fault that she became like this, and also my fault she ended letting that monster from another world brainwash her to this extent… If there's someone to blame, it is me."

"Is she still the vessel of that monster?" Flora wondered. "If she still is…!"

"Calm down." Zehe sighed. "I've managed to cut the bond between her and him, now she's free… Hopefully. However, even then, we need to be careful of her. She's still a powerful Supreme Goddess thar rules Death. Loki, your strength is not enough to contain her."

"But we're here as well." Fenrir nodded.

"That's right." Jormungandr nodded.

"I-I'll help too." Yiksukesh nodded.

"Well… I guess there's no helping it." Flora sighed. "However, if she dares do something suspicious… I won't be so merciful. Now… We should-"

RUMBLE!!!

The entire Realm of Helheim started trembling, just when everyone believed this nightmare had finally come to an end. The ground, however, didn't shake, nor tentacles emerged from the floor either.

However, the skies of the Realm started changing and shapeshifting constantly, becoming a mass of spiraling black clouds, with countless red eyes glancing at everyone… The skies were actually the Soul Manifestation of an incredibly powerful being.

"T-This presence…" Annabelle started trembling behind her brother. "H-He's not gone yet, big brother…! T-That monster will never give up Lady Hel's body! We're all doomed! Our souls… will be torn apart!"

"Annabelle! Calm down!" Redgaria tried calming down his sister, but it seemed as if she was going mad the moment she glanced into the sky.

"Ungh…! That sky, those eyes…" Rimuru muttered. "It just annoying, but I can tell that weak people will get affected by those eyes and might even go mad! Put her inside my divine realm asap guuu!"

"O-Okay! Annabelle, everything's going to be alright! Sapphira, take care of her please." Redgaria said.

"I will!" Sapphira nodded, as she and Annabelle were sent inside of Rimuru's Divine Realm, to safety.

"Hel, you better rest while you can." Loki sighed, bringing her to her own Divine Realm, but failing to do so. "Ugh… W-Why I can't bring her inside?!"

"It's because she's a Supreme Goddess and you aren't." Said Flora. "For now, just carry her around! She's tough enough. But what's important is… This damn bastard! Has he come again?! But without a vessel how is he doing this?!"

"Hehehe… HAHAHAHA! I've tricked you all, stupid insects!" Laughed the Necrotic Plane Ruler's voice, echoing from the skies. "Did you really thought that child was what my vessel truly would be?! This entire time… I've only aimed at the real treasure in this place. She was simply a connection to it! And I've bought enough time for this vessel to completely become mine!"

"Vessel?! The sky, guu?!" Rimuru was confused.

"The Sky…?" Laughed the Necrotic Plane Ruler. "It is something much more powerful, this whole Realm has slowly transformed into my body! Those stone-made tentacles you fought before? They were merely me peeling off the skin!"

RUMBLE! RUMBLE! RUMBLE!

The entire Realm of Helheim started trembling as everyone panicked. Swiftly, everyone started flying into the sky in panic, as they saw the entire Realm of Helheim slowly shapeshifting into a sphere.

The ground and stone covering it began peeling itself off, as everyone saw in horror black and red colored flesh pulsating from within its interior, countless red veins spreading blood and necrotic energy…

"W-What is this?!"

CRASH… CRAAAASH!

The ground kept shattering, whole continents within the Realm shattering into rubble, tearing themselves apart constantly, as huge muscular arms and tentacles surged from within, amorphously, and monstrously.

Beneath the surface of the Realm of Helheim, a monstrous, huge fetus-like creature was growing! This was the true vessel of the Necrotic Plane Ruler, and from within its chest, a big, crystal glowed brightly, emanating cosmic energy, divine energy, and even the primordial powers of the Laws of Genesis.

Indeed, it was a Primordial Law Fragment from Genesis herself! This was the "Realm Core" of Helheim itself, and what the Necrotic Ruler was aiming for from the very start!

"A new body that is both alive and dead! My true new form, my true new body! With this body I will traverse countless worlds, countless universes, and I will devour it all! GAHAHAHAHA!" He laughed maliciously, sending shivers down the spine of everybody.

His power… clearly surpassing a Supreme God at its peak, Flora and Aura together were still no match against the enormous quantity of power his new vessel exuded.

Even the skies were merely the aura the entire body exuded!

"NOW WATCH AS I DEVOUR YOUR WORLD!"

Huge tentacles, longer than anything anybody had seen spread out of his body, reaching nearby smaller Realms, and piercing their smaller crystalized cores, dragging them along and then being devoured one after another by gigantic jaws spread across his amorphous body.

CRUNCH! CRUNCH! CRUNCH! CRUNCH!
