The many demons within the Pandemonium of Greed were left completely speechless. They were all looking at the many fights at the same time but seeing a mere slime of such power was something they usually never saw before.
Although there were some strong slime-like creatures around the Layers of Hell, there was nothing as powerful and amazing as Rimuru and Popi. Their combined attacks were wonderful in every way possible, and Mammon couldn't help but have his eyes fixated in the cute Rimuru.
"Kyaaah~ Rimuru-chan, you're so cool and cute! Kireina-chan's memories of you are all right, you're such a cutie!" said Mammon while moving around weirdly, Plutus sighed as he saw his master act strangely once more. The strangeness of Mammon wasn't going to stop at any moment. The powerful Mammon, the Demon of Greed, had been acting like this all this time since it fused with Kireina's soul fragments, yet Plutus had yet to become completely accustomed to this…
Meanwhile, the people of the Pandemonium of Greed all looked at Rimuru's excellent performance with eyes wide open! …and some of them gone completely blind due to how bright her powers were!
"Amazing… She's really incredible!"
"She can fight such a strong entity that can instantly kill us… like nothing!"
"Is she really a slime?! Are we sure of that?!"
"And not only her, but there is that little fellow, the Blue Slime!"
"That Blue Slime hasn't even showed its full strength yet… but it is amazing already! So strong!"

"L-Look, that damn invader got a second air!"
"Will the Slimes be able to defeat it now?!"
"I am honestly rooting for them!"
"Me too! They're so cute!"
The demons were captivated by Rimuru and Popi's cuteness, and were all rooting for them as if they were watching a TV Show or something!
However, things were not done yet!
"CRYYAAAAAA!"
As the massive explosion of rainbow flames engulfed the deathly Necrotic Death Lord and his Death Titan, he desperately used all the materials he had at his disposal, which included a lot of these Phoenix-type Undead Beasts which grew inside of his Nether Realm!
Using these materials, the entirety of the Death Titan underwent an evolution and became a Death Phoenix Titan of amazing strength! With this power, the gigantic beast gained incredibly and unprecedented new power, and its entire wings expanded wildly all around the place, unleashing gigantic amounts of deathly Necrotic Power and Death itself!
"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!
The rainbow flames covering the entire area were cleansed in an instant as the powerful and gigantic Death Phoenix Titan was ready to fight!
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!"
Popi grew in rainbow color as he began to flash with bright light, his entire body bubbled around with immense rainbow beauty, the power it held was now being enhanced through his strong bond with Rimuru-chan! Popi's eyes shone brightly as his entire body underwent a temporary transformation, from ordinary Blue Slime, he evolved into an Emperor Rainbow Slime!

"POPIIIII!!!"
"Slime Rainbow Meteor!" said Rimuru, as she unleashed another Special Technique of her Path Jewels, the Gates of Nirvana suddenly fused with Popi and Popi grew into a massive size! Its entire body began to self-divide into countless of tiny Popis, well, as tiny as a car! And each one of them began to fall over the massive Phoenix with great speed, flashing light, and wondrous colors!
FLASH! FLASH! FLASH! FLASH! FLASH!
The Necrotic Death Lord within the Death Phoenix Titan ordered the titan to quickly flap its wings, unleashing a barrage of phantom flames like a storm! Additionally, many black feathers came out of the twins flapping around, coating themselves in these flames and clashing against the meteors made of rainbow slimes!
BOOOM! BOOOM! BOOOM! BOOOM! BOOOM!
Enormous explosions ensued all around as rainbow and darkness clashed against one another in an incredible display of power that the demons in the citadel couldn't believe their eyes! They were all rooting for Rimuru to win though!
Rimuru, however, wasn't going to stay still as her amazing Popi unleashed a barrage of constant meteors made of his body covered in rainbow light, as Rimuru flew towards the Phoenix to attack it from behind! Her entire body suddenly was encompassed by a beautiful light as she unleashed several skills and path jewel abilities, even armor and other things she had devoured and could self-replicate into an amazing new grades of quality!
All of them combined together and coated all of Rimuru's soft slimy body with the power of a mechanic rainbow-gold armor!
FLASH!
Rimuru suddenly transformed into an amazing-looking feminine-styled Gundam-like mech! And then, two enormous blades were materialized at each side of the mechs' hands, overflowing with Supreme Divine Power!
SLASH! SLASH!
