Moving on, the Frost Wendigo, a creature resembling a monstrous and vicious Undead covered in blood, flesh, and animal pelt was exposed to miasma and named, evolving into a Winter Wendigo Queen, it seemed to be a female, and when it evolved, it gained the ability to take into a female form resembling a half-goat woman with pale-white skin and wearing the skull of a goat over her head, while covering her body with animal pelt… She was able to speak and became as strong as an SSS-Rank. ​​

The Blood Thrall was interesting, it seemed to be a lesser caste of Vampire, originally probably an elf or a human who was infected with the blood of a Vampire but that was not able to fully become one, and ended as a feral humanoid monster with some beastly vampire-like capabilities. After it was exposed to miasma and named, it evolved into a High Blood Elf, regained sentience, and acquired abilities similar to Natalia, becoming an SSS-Rank monster. It was still mostly beastly though, so it had some time to adapt to its newfound intelligence.

Another interesting specimen was the Treasure Chest Mimic! An infamous monster from Dungeons that pretends to be a treasure chest to attack unsuspecting visitors who believe to have found some nice loot in the way, it quickly catches them off guard and usually devours them in a single chomp, crushing them with its many razor-sharp teeth.

Chaos had inspected its interior and it seemed that the treasure chest was something like its shell, while the fleshy, red-colored monster inside was something similar to a mollusk. It was mostly gentle with Chaos, as it licked him with its giant tongue.

After it was exposed to miasma and then named, it evolved into a powerful Greater Treasure Chest Mimic and then into a Doppelganger, gaining not only the ability to shapeshift into a treasure chest but also other forms and more, this powerful being had the strength equal to an X-Rank monster, but it had much to discover… Chaos named it Boxxy.

And lastly, the Fire Demon Ifrit, Ifrit, had evolved once when he was named Ifrit, and then once more after being exposed to a lot of Miasma, becoming a High Infernal Demon Ifrit King, gaining the size of around four meters now, and acquiring many pointy horns across his body, alongside a long hair made of flames. Chaos pointed out how he looked particularly tasty, and that he couldn't help but wonder what Skills he could get from him, scaring the shit out of the Demon. However, Chaos had done as he promised and only said such things but never tried to devour him… Ifrit became peak X-Rank after this.

After everything was said and done, Chaos felt particularly tired. Each time he used large amounts of miasma to evolve many beings, he felt exhausted, perhaps he wasn't as invisible and tireless as he had imagined he would be, however, this probably was related not to his body but his very soul.

The chaos and miasma he produces come from his very Chaotic Soul, meaning that the more he uses, the more he consumes the very mass of his soul, which requires slowly recovery as his mana does. Perhaps the reason why he has so much mana is that his soul is immense and filled with empty space where mana can be stored, but even then, if he consumes too much of his soul, he will feel tired and require a nap of a few hours.

His servants had begun to wonder if he required to strengthen his soul in some way, and Belphegor had begun to think that perhaps teaching him how to devour souls to strengthen his own could be a good thing to do.

"For now I shall go gather a few hundred wandering souls for my lord alongside the Skeletons and Ghosts, all of you go hunt as well, so we can greet him with a large feast of varied types of beasts, this way he will be able to grow by devouring and gaining Skills," said Belphegor, ordering everyone else to get moving.

As Chaos slept, he and most of the ethereal-type Undead went to gather wandering souls through the area, which would be rather difficult for normal people or weak Undead, but for him and the Undead at his side, it wasn't so hard.

They merely create giant nets with their phantasmal bodies and gathered souls like fish in the ocean, while the Skeletons watched over and killed any other monster that seemed to come near them.

"Oh! There's a big one, I bet this one will be liked by my lord!"

Meanwhile, Abyss led a hunting team with other members, such as some of the Orcs led by Dura, Natalia, and other of the newly summoned and upgraded monsters, who practiced their skills.

The area around the castle was mostly peaceful when Ainz was here or when the barrier was erected, but now that everything seemed empty, monsters continuously tried to move into the castle and destroy it. It was sometimes strange to see the monsters being so obsessed with this, but it seemed that it was because of the Miasma that Chaos produced naturally.

Monsters are creatures that enjoy being near high-miasma zones, and Chaos who constantly produced it was showering his entire place with miasma, the more he used, the more attractive this place became, even making the beasts insane and getting obsessed with getting inside the castle and find Chaos…

BOOOM!

Abyss shapeshifted her slime body into a giant fist, crushing a Nether Dark Wyvern into the ground and splattering its head across the stone floor, it was a strong SS-Rank monster, but to her it was but a fly she slapped to death.

Abyss pointed out that the creature was particularly big, as it seemed to be a fully matured adult whose strength can be comparable to an SSS-Rank monster. Sadly, she was already a strong Pseudo-Demi-Deity, so the wyvern was annihilated rather swiftly.

Meanwhile, Natalia went around, trying out her new abilities and honing her techniques…
