Epic of Caterpillar

The Necrotic Death Lord felt ridiculed! How come it was possible for pathetic low-level trash-tier beings such as Slimes to be this strong?! There were two at Supreme God-level fighting against him right about now, and their power was incredibly commendable!

The amazing power that Rimuru and Popi exuded wasn't without effort in acquiring it, Rimuru had been slowly growing stronger since Kireina's journey began, at her side, she had been growing and leveling up, evolving at the side of her Masta, and becoming more and more beautiful in the way as well!

The beautiful Rimuru turned out to be an amazing Supreme Goddess at the end, after all of such efforts and the countless adventures she had lived with her beloved Master and wife! She felt so vibrant an energetic by simply thinking in how far she had gone through that she continued to conjure her powerful Gate of Nirvana, which was an amazingly powerful enhanced version of the Gates of Bjarmia that Kireina had made long ago.

Rimuru had created her won version back then, which she slowly upgraded on her own. Each time she did, she added more and more elements of the ones she learned by herself, enhancing the entirety of the Skill through the infusion of many new spiritual elements into it! the many projectiles were made out of crystallized elements that detonated into deadly explosions when they were to hit their target!

She continued to pour her power into it as the Gates of Nirvana actually had many stages now that Rimuru had made a Path Jewel out of it as well, she quickly began to conjure new Abilities on it as she saw that the Necrotic Death Lord was still relentlessly picking up the pace and fighting against Popi. Rimuru knew that Popi alone wouldn't be able to fight off the entirety of the Death Titan alone!

"Popiiii…!"

Popi was buying time for Rimuru but that time was simply half a second, that was more than enough!

"Gates of Nirvana: Bifrost Judgement!"

FLASH!

The entirety of the rainbow-colored gate suddenly shone with new light as from within, a new power emerged! The immense quantities of spiritual energy and divine energy infused into it all merged together in literally an instant through the ability of her Path Jewel, as a massive rainbow ice emerged out of it, in the shape of a gigantic ray!

BOOOOOOMMM!!!!

"GRUUUUAGGGHH…!"

The Necrotic Death Lord felt overwhelmed in an instant as it was suddenly attacked by a massive ray of rainbow ice! The massive attack reached his gigantic body, pushing him down from attacking the relentless Popi as it fell over the floor once more. The enormous Death Titan began to slowly freeze, covered in all this rainbow ice!

"And now… Vibrant Spiritual Explosion!" said Rimuru, once more conjuring a special ability within her personal assortment of Path Jewels, this one allowed her to detonate immediately any attack made out of the materialization of crystallization of her elemental spiritual light power!

FLASH!

"Unngh?! W-What is thissssss?!"

The Necrotic Death Lord cried in agony and confusion as the ice that covered its entire body wouldn't let it move an inch! However, that wasn't all as the ice glowed with such bright light that it emanated a blinding rainbow aura all around itself! The entirety of this spectacle of such colors that many of the spectators within the Pandemonium of Greed had to cover their eyes from the detonation due to how bright and intense it was!

But that wasn't even the main dish, as the entirety of the ice began to crack and then…!

BOOOOOOOMMM!!!

It exploded!

The massive rainbow explosion consumed the entirety of the Death Lord in an instant, the incredible and painful attack made the massive creature groan in agony as his entire body was being consumed by this multi-elemental spiritual bright light that could consume all things!

The massive attack consumed the death incarnate and the entirety of the Necrotic Death Lord! It was hopeless!

The flames of rainbow colors coated the entirety of this area of the battlefield, as they completely consumed the normal and every day seen red flames of Hell, covering the entirety of the place in a beautiful rainbowy scene…

These rainbow flames, however, were not everything, as the massive explosion actually didn't killed the Necrotic Death Lord nor his Death Titan! However, something from within emerged after the smoke dissipated, surprising Rimuru and Popi!

"Hm? That's… it transformed!" said Rimuru in shock.

The massive death titan had undergone a complete change from before as many of the spectators had seen the same thing happening with Kireina's fight, however, this time around the titan turned into a being made of phantasmal black flames! It was encompassed by them, and it had the shape of a roaring phoenix of death!

"CRYYYAAAAAAA!"

The gigantic beast groaned; the Necrotic Death Lord had used the same technique as the other Necrotic Death Lord that Kireina was fighting! That Necrotic Death Lord had used the power of his Necrotic Materials, infusing them into his Death Titan through the usage of the Dao of Necromancy and upgrading and evolving the massive Death Incarnation into a powerful Death Titan Dragon!

The thing happening right now was very similar, but instead of draconic materials, the Necrotic Death Lord fighting Rimuru, unlike the Necrotic Death Lord, had used the power of phoenix-type beasts' necrotic materials, Black Death Phoenix, Skeleton Phoenix, Phantom Flame Phoenix Emperors, and more! all of such beasts that were around the same power level as Supreme Divine Beasts! Their materials of great power were infused into the deadly and powerful Death Titan, transforming it into an even more insanely powerful Death Phoenix Titan!

"CRYYYAAAAAAAA!!!"

The massive bird extended its wings and unleashed a powerful aura of darkness and death that consumed everything around, forming a sky of darkness atop the battlefield!

Rimuru and Popi quickly gathered back up together as they prepared to confront this beast, unleashing their powers together, Popi suddenly shone brightly as the colors of the rainbow made up his body now!

"Popiiiii!"
