"Aaaahh~!"

Abyss adorably sang while shapeshifting into a monstrous beast, she floated over the ground naturally by propelling herself using the vast mana that she possessed (at 10 million) by creating a fog of miasma from her soul.

As she flew around and caught the bats to crush them with her shapeshifting body and adding them into her own mass, she continued to sing an eerie song that made the Bats go insane!

As the Bats specialized at earing, her high pitch song began to break their minds! Especially because she infused her voice with the power of the [Hideous Songstress] Ability, inflicting all sorts of status effects to those she targeted with her songs!

"Laa~ Laa~ Laaaa~~~!"

Her monstrous voice resonated through the walls, the soundwaves coming back after hitting the walls and inflicting even more horrible effects over the bats!

They began to tremble, to convulse, to fall into the ground and die crushed by their own weight, to vomit blood, to cry desperately, and some even suffered the worst possible effect, which made their heads literally explode like a balloon!

Afterward, Abyss used Multi-Attack and Crushing Charge to rush towards the confused and paralyzed bats, hitting them continuously with her tentacles and then crushing them with the weight of her expanding body.

CRASH! CRASH! CRASH!

"Haha! This is so much funnnn! Boop!" said Abyss, as she touched a bat with the tip of her tentacle and impaled it from the head down the crotch, slicing it in half and then consuming it in a bloody manner…

Chaos felt happy that both of his party members were having fun, and he continued to use his combination of Blazing Stab and Storming Stab, merging it with Orc's Burly Physique and Orc's Wrathful Charge to enhance his power to an even greater capacity, anything that got near him was easily crushed into nothing.

At the same time, as he annihilated his prey, he felt a constant flow of energies entering his body, certainly, there was no levels nor exp in this system, but he was able to gain several types of energies the moment he slew a beast, it was as if he was gaining experience.

Belphegor had explained to him beforehand that any living being grew stronger by slaying and consuming the vitality, mana, and soul energies of their prey.

There were other ways to gain energy, such as devouring the prey's corpse or consuming high-quality potions, concoctions, pills, and other consumable items too, or there were also special magic formations that Ainz used to gather mana from the miasma of the environment and absorb this energy to enhance his cultivation of existence realm.

There were many ways to grow stronger, but the simplest one was to slay a living (or unliving) being and naturally absorb their essence, which usually occurred naturally and instinctively.

Whatever was this world, Chaos didn't remember such a thing being possible on Earth… Perhaps the System itself gave this natural ability that didn't reflect itself as a Skill.

The way one advanced through existence realms was rather simple, by accumulating energies of these three types by all the means listed before, one could slowly get through them and reach higher.

There were many ways and techniques to cultivate one internal energy, some races such as Vampires and Dragons possessed special organs that helped them gather these energies faster than others, such as the Blood Core that could gather energies faster, and also absorb blood for nourishment, while Dragon Hearts did the same but could also absorb vitality easily by digesting previously killed living beings, and because Dragons had great digestion, they could eat anything.

However, there were also races such as Humans who usually didn't possess any of such organs and had a harder time cultivating than others, although humans often belonged to ancient nations across the galaxy, and had many means to hasten their cultivation through their cooperation, such as making pills through alchemy, concoctions, potions, magic formations, and more… There were some powerful mages that had even been capable of creating things such as Mana Cores to cultivate their magic faster.

Chaos recalled this information as he deepened his understanding of the laws of this universe, it was clear that in this vast cosmos, only the strong thrived, while the weak were hidden and were eaten by the strong… After all, by killing anyone you would be able to slowly raise your cultivation, so larger nations needed to implement strict laws, alongside incentivizing companionship to stay afloat.

"I think we are done, my lord! It has been a long time since I fought! I was quite rusty," laughed Belphegor.

"No, you were amazing, good work," said Chaos.

"Oh, you flatter me, my lord," said Belphegor while flying down below with Chaos and Abyss.

"It was fun! I am now full too! Ah, did you like my son, Chaos? It was a song for you!" said Abyss cutely.

"Yes, it was very beautiful Abyss, you're very talented," said Chaos, who was completely unaffected by her negative effects within her atrocious and monstrous voice. Chaos was actually being honest, he had found it quite good because he had never heard music, to begin with, so anything that sounded "interesting" other than plain silence was good for him.

"Hehe, I will make sure to sing for you every day then!" said Abyss with a gentle smile, as Chaos felt happy over it.

The trio quickly descended into the ground and Chaos and Abyss quickly began to feast in the corpses.

Chaos tasted the grilled bats, they were crunchy, and the grilled meat was rather tasty, the insides were warm ad smoky, and overall, it left him happy. Although now that he had tasted salted meat, he desired to sprinkle some salt over it, that might be for another time.

He also drank liters after liters of blood, and nourished himself well enough, even managing to increase his cultivation and stats by a bit.
