"Amazing! Wonderful! Sublime! Outstanding! That's my lord! Chaos!!!" cheered Belphegor, as his flames roared everywhere, and suddenly took the shape of many skeletons cheering for Chaos as if he were a whole stadium.

"Sublime, Master! You dealt with it so amazingly well!" said Abyss.

Chaos ignored his servants for a few seconds as he was receiving a sudden infusion of life energy from the dragon he killed as if it were EXP in an RPG game, any time someone slew another being in this world, their existence rank would receive a little boost, getting them closer (by a little bit) to the next stage or realm, although this obviously varied, the bigger, stronger, and ferocious the killed being, the more essence could be acquired from it after killing it. And just like games, if many defeated a single entity, the essence would be shared around.

However, by killing alone one would take ages to increase cultivation, the real ways to do it was by extracting materials, corpses, and so on, and use their essence to make all sorts of items, concoctions, pills, potions, or certain aces such as dragons, who didn't need to do all of this and could directly devour their prey to get all of their essences is how one could be able to properly increase cultivation.

However, killing a dragon only gave him the little essence that encompassed it, but Chaos needed to devour its flesh and drink its blood to get all the power!

Chaos quickly opened his eyes once more as he descended into the surface.

"It was an enriching experience… The pain was rather annoying, but I believe I learned some things with this fight," said Chaos. He sounded like a child merely understanding the world, yet he was a terrifying being capable of beating a Blazing Fire Dragon, a peak X-Rank being.

"And you did it wonderfully, you're learning things step by step, my lord, well done!" said Belphegor, petting Chaos head with his phantom flare hands as he floated up above.

"Yeah, it was very fun to watch you fight, though I was a bit worried…" said Abyss.

"Sorry for making you worry," said Chaos, shapeshifting back to his humanoid form and caressing Abyss's head.

"Now, we got a large number of offerings for you, my lord!" said Belphegor, as he and Abyss showed Chaos the pile of Wyrms they had killed, which include the piranha-like ones and the alligator-like ones by the dozens!

And alongside that, there was the delicious Blazing Fire Dragon corpse, ready to be devoured!

The trio had not realized that they had mostly wiped out the entire biome, and that deep into the cave, there was a staircase that led to the lower floors. This entire biome was around 20 floors in total, with the other biomes around being 20 more.

"Let's go back home, for now, I want to eat all of this, and rest a bit, perhaps we can summon more servants as well," said Chaos, as he began to save everything inside his Inventory Skill.

"Very well my lord!" said Belphegor.

"Let's go then!" said Abyss.

Chaos and Belphegor created several runes in the ground, which Chaos made using the [Magic Rune Creation] that he got from the sealed demons.

Magic Runes were high quantities of mana infused into a certain solid object, which took the shape of something. The more intent was put into them, alongside mana, the greater they could become.

Chaos had over 100 million mana, meaning that he could do something amazing runes.

The runes were needed to put the teleportation jewel and activate it, while also leaving it here infused into the ground as a rune as well, which can also be retrieved conveniently.

When the rune formation was done, which was fairly easily done with Belphegor's guidance, the group quickly disappeared from the dungeon, while leaving the imprinted formation into the dungeon's impenetrable ground…

Meanwhile, the dungeon itself was rather annoyed, or more like, incredibly annoyed.

One of the strongest monsters that there were in the dungeon, the Blazing Fire Dragon, was dead just like that! And even more, the entire biome was emptied!

It was horrifying! Such might… would the dungeon end succumbing to the vicious nature of Chaos, or would it be able to fight back against him and manage to somehow defeat him and gain energy from it?

The Boundless Abyss Dungeon Core was a vicious predator, like many other dungeons around the world, so it wasn't going to easily give up… although it wasn't as if it could really do much, to begin with, other than controlling the wave of monsters or things such as those…

Flash!

Chaos, Belphegor, and Abyss reached the castle in a second, emerging inside the underground room where many of the artifacts were, alongside the summoning artifact where Abyss came from.

"Oh, my birthplace, it has been less than a day and I already have some nostalgia!" said Abyss.

"Has it really been less than a day?" wondered Chaos, who had lost many perceptions of time.

"I have been counting the hours, my lord, although it seemed quick, we spent around two days inside the dungeon, so this could be your third or fourth day in this world! Although you are 50 years old, so I guess it is not," said Belphegor.

"Eh? That much time went by? Hm… I suppose the battle against the dragon was longer than I thought…" said Chaos.

"Indeed it was! It was frustrating to see my lord being thrashed around, but it seems that from such a beating, you've managed to learn more about fighting, so it was an enriching experience for your development into the ultimate evil lord," said Belphegor.

Chaos didn't know what to think about such a statement, he didn't particularly mind being called good or evil, as such concepts seemed to not really weigh down to anything other than personal biases. He was unhindered by them, and did as he pleased, no matter if that was for some good or others evil…

But he still thought that he wouldn't prefer to be called evil because it reminded him of his curse, which made him quite annoyed…

Although he quickly shrugged it off and decided to go eat his meal.
