The energies of the Necrotic Plane infested the Spiritual Plane as Kireina descended from the skies! Not only stopping the largest threat that could had finished Skadi and her allies but undergoing an incredible transformation and summoning a horde of over a thousand Undead!
All the Undead varied in shapes and forms. From Titan Skeletons to Skeleton Knights, Toxic Zombies, Zombie Beasts, Bone Beasts, Phantasmal Aberrations, and many of them, Undead Insectoid Spirit Beasts!
Indeed, something that had never seen before in this Plane happened as Kireina infested the very fabric of this reality, poisoning it with the energy of another Plane that had yet to invade this one.
"T-That energy…! Is that Necrotic Energy?!"
"She… She's bad news!"
"Should we retreat?!"
"Lady Hedlehash!"
The dozens of Spiritian Sorcerers accompanying Hedlehash started to panic the moment they saw Kireina's Undead Army. Which thanks to her pre-existing Path Jewel of Necromancy, had only become stronger!
"SHUT UP!" Hedlehash roared furiously, concentrating her energies as she absorbed many more Spirit Hearts she had stored within her Spiritual Realm, a special Dimension that Spiritians could access to like Divine Realms once they achieved a high enough Rank. "Her pathetic army of Undead has no power over mine! I am the Sorceress of Swarms! I am the Queen of Insectoids!"
With a furious and prideful scream, Hedlehash continued expanding her Spiritual Domains, imbuing them with large quantities of Spiritual Energy, as more and more Insectoids were being summoned, their numbers now reaching almost ten thousand!
Like a cloud of endless destruction, they neared towards Kireina, attempting to deal with her and also get down to kill everyone else, that were already weakened.
But Kireina was simply not going to allow that to happen.
"Know your place! [Abyssal Bloodshed Enhancement]! [Black Bone Armor]! [Necrotic Boost]!"
Ding!
[You have conjured [Abyssal Bloodshed Enhancement], all your Undead Horde's Offensive Power has increased by +200%!]
[You have conjured [Black Bone Armor], all your Undead Horde's Defensive Power has increased by +200%!]
[You have conjured [Necrotic Boost], all your Undead Horde's Necrotic Power has increased by +200%!]
Her Undead suddenly gained three buffs at the same time. Their bodies overflowing with crimson-colored auras of wrath, as they gained huge black bone armors, and a necrotic energy boost to make them even mightier on top of that.
"GRAAAAAH!"
"GROOOOHH!"
"RAAAHHHH!"
"KILL! OBEY THE QUEEN!!!"
With furious and monstrous screams, the Undead flew into the skies, floating into the air with no problems at all, and clashing against the Insectoid Spirit Beasts and the Insectoid Kings!
The sounds of both armies bodies being splattered into pieces resonated soundly everywhere, Skadi and everyone else below could only glance at the scene, dumbfounded!
CRASH! CRASH! CRASH! CRASH!
The Undead ended still being much frailer, many were being torn apart into pieces, only for them to regenerate back in seconds, unifying into horrendous chimeric aberrations, tenaciously coming back over and over and over again!
To make things worse, any Insectoid Spirit Beast that was killed would quickly return as an Undead. At first Kireina's army seemed at a disadvantage, but over time, they started to grow in numbers at a massive, explosive rate!
From merely a thousand to two thousand, three thousand, four thousand, five thousand!
"You're never going to defeat my Undead Army as long as I am alive, dear."
Kireina's eyes glanced through all things, shining with cosmic radiance, as the Wasp-like woman behind the portal shook, feeling a shiver down her spine, as she saw the illusion of Kireina's eyes glancing at her!
"S-She noticed me?!"
Hedlehash suddenly felt the urge to escape! It felt as if Kireina had set her eyes on her, and if she didn't go somewhere far, very far away…
She would get eaten!
"N-No! I won't let you intimidate me!"
The Sorceress of Insectoids and Parasites waved her hand angrily, her powerful Spiritual Energy imbuing itself into her Insectoids.
In that moment, hundreds of them gathered together, fusing into Insectoid Great Kings, even stronger than the Kings alone, and they started rushing towards Kireina by the dozens!
"[Abyssal Phantasmal Legion]! Protect me!"
Kireina didn't even felt like moving, simply raising her Path Jewel of Necromancy as her Undead gathered, forming a gigantic wall, overflowing with Phantoms fusing into them, blocking all blows from the giant insectoid great kings!
CRAASH! CRAASH! CRAASH! CRAASH!
"Now's my turn." Kireina smiled. "[Undead Fusion]! [Great Undead King]!"
FLUOOOSH!
The Undead began to gather together, as Kireina fused her own Dao of Domination and Swarms into the Daos of Necromancy and Undead, making it possible for the Undead to merge together into larger, monstrous, and greater beings!
"GROOOAAARRRRRR!"
A gigantic wolf-like monster appeared, made of countless bones, spiritual crystals, phantoms, and rotten flesh, as big as two hundred meters, leaping over the insectoid great kings and tearing them apart with its sharp claws!
CRAASH! CRAASH! CRAASH!
The giant bugs started falling one after another, only to quickly raise, changing their colorful crystal bodies and gaining darker colors instead, their eyes no longer glowing blue but red, emanating a combination of corrupted spiritual energy and necrotic energy!
"Rise! Rise! Rise! Fight, my minions! Slash them! Tear them apart!"
Kireina was completely high due to the large quantities of Necrotic Energy flowing into her, as if its powers were making her feel euphoric. The Undead kept multiplying, advancing further, and further.
More Great Undead Kings were born, in the shape of simple beasts such as lions, snakes, sharks, and birds, pushing forward more and more. Some died, but their materials became new Undead, it as an endless cycle!
Even above the High Heavens, the Ruler and her strongest Generals felt shaken as the Presence of Kireina felt the strongest in this moment… However, it didn't just felt like Kireina herself.
It felt as if there was now a second Ruler of the Necrotic Plane, who had boldly decided to invade their Plane!
After having eaten so much out of his Soul, Kireina's presence while in her current transformation already exuded the mighty power of such a Ruler.
And it didn't took that long until her army was already swarming all over the Neighboring Sky Island, beginning to attack their barrier instead!
"Kill her already, you useless beast!!!"
"GROOOAAARR!!!"
However, Hedlehash had yet to give up.
