My World Traveling System: The Harbinger of Death

-----

Frank's sight was greeted by several system notifications, aside from his leveling up, he also leveled up some Skills, and also completed some tasks. ​​

It seemed that he had already completed a few tasks before, but he had decided to not check while he was running around the dungeon with his party.

Ding!

Huh? How did you even do this one quest, it was super-hidden!

Well, congratulations, I guess!

You got pretty lucky there, I guess you were quite unlucky before, so karma has now balanced itself…

Does Karma even exist?

Well, you might one day find out.

[Become a Necromancer and Raise the Dead!] (Hidden Quest) Completed!

This is another hidden quest that you were not supposed to complete yet…!

But I guess you somehow did it, didn't you, big guy?

Anyways, it is not like I AM GETTING ANGRY OR SOMETHING.

I am just a quest, after all!

Congratulations, mister necromancer!

I hope you do not lose your connection with the living by being too much with the unliving.

[Defeat the Giant Black Scorpion King and Complete the Dark Lair Dungeon!] Completed!

Amazing, good work!

You actually defeated this super powerful Dungeon Boss!

Monsters in Terra are way stronger than in Earth, isn't it?

This is because they take a lot of time to grow, you actually killed a being that had survived and sharpened its skills for many years, a true predator and king of the dungeon.

Amazing, amazing!

…But is that it?

After all, it was still a Rank 1 monster…

Can you even imagine a Rank 3 Boss Monster?

Or a Rank 6?

Or Rank 10?

Do you think that one day you will be able to defeat one?

"Three Quests? Seriously…? Well, I can't complain about rewards… And these Quest descriptions get weirder and weirder, is that Gaia the one talking to me? She really has a sassy personality… Is this really the planet am I trying to save? Sigh…" said Frank.

Ding!

[Proclaimed Dungeons: None.

"T-This is ridiculous! Do any Adventurer that defeats a Boss in Terra get this spell…? …No, wait, no one here has this System. Does this mean… that this System itself is giving such an ability? It is clearly not something natural of this world, no mortal should be even capable of stealing a dungeon from the Goddess of Chaos… This is… a lot to process right now, but I can't help but feel like if I don't take this Dungeon with me, I will be missing in something big…" Frank said, as Hades floated at his side with confusion.

"Hm? What are you babbling about, kid? You won, celebrate!" said Hades.

Frank then explained a bit to Hades what had just happened.

"…What?! What kind of almighty System is this?! Aren't you a tad bit too ridiculous, brat?!" asked Hades in disbelief.

"Y-Yeah, I was a bit surprised at first as well… Just what kind of power can let me simply take over a Dungeon's authority just like that? I doubt I am strong enough to be a god yet, even if I got a fragment of you inside of my soul…" said Frank.

"Hm… Right. Perhaps that triggered it? You know that Gods are the ones that create Dungeons, right? If you have within your soul the piece of a god, you might be already qualified for such a thing…" said Hades.

"That's… I guess it makes some sense? But still, it's a bit ridiculous," said Frank.

"It is! It really is! …But as my successor, I can't help but feel proud! Now take this damn dungeon for yourself, brat!" said Hades.

"But what about the Goddess of Chaos, will she get angry?" asked Frank.

"Bah! Didn't you say that this territory is part of that other God, one of the Beasts? If she gets angry she will have to fight against your beast pal, and I bet that he can fend her off now that he regained his power since you healed his wounds," said Hades.

"Hm… You are manipulating me a bit there, I see how's it going… But alright, I am just as excited about this, so I will simply give in to my desires for once," said Frank, choosing 'Yes' in the window that asked him if he wanted to proclaim this dungeon as his.

The moment Frank pressed 'Yes', the entire Dungeon's trembled.

Boom!

"It's trembling?!" asked Hades.

"My lord, what's happening?!" asked Nezhit.

"Err, just remain still for a bit…" said Frank with an apologetic smile, as the dungeon stopped trembling just as he said those words.

Flash!

Suddenly, Frank's entire body was engulfed in all-encompassing energy, a power surging from the dungeon itself!

Frank could feel that his very soul was absorbing such power, which seemed almost endless!

"Nngh…!"

However, it was not endless, as the energy stopped surging after a few seconds, leaving Frank exhausted, yet overflowing with a new power…

Alongside this power, a surge of the information entered his mind, teaching him the very basics about dungeon maintenance and how Dungeons worked in Terra, which left Frank baffled, to say the least.

Ding!

[Soul Connection with [Dungeon Core: #12434] has been successful!]

[You have taken the authority of the [Dark Lair (Rank 1)] Dungeon!]

[You unlocked the [Dungeon Maintenance] System Function!]

-----

Within the depths of the Dark Lair Dungeon, laid a secret chamber, not connected to any floor or room, completely isolated from the outside world and the 'outside dungeon'.

From ancient times that such chamber existed, from the ages where the dungeons were still popping up around Terra as the Goddess of Chaos created them one by one, slowly but steadily covering the world with them.

Each Dungeon possessed this special chamber, where no mortal could ever enter other than the Goddess herself, a special place where one of the most important parts of a dungeon rested within, assessing the immense structure in silence for thousands of years.

Inside such a large chamber, there was a large sphere glowing brightly, resting over an altar made out of a gold-like metal of indestructible qualities, Orichalcum, a metal that only gods could create.

The white orb glowed brightly, seemingly in peace…

Until suddenly, the presence of something overwhelming took over its entire being!

Flash!

The presence resembled a dark shadow, enveloping the entire glowing orb, which seemed frightened!

"W-What?! What is happening?! Let me sleep!" it cried with the innocent voice of a child.

However, the powerful force kept covering the glowing orb, and helpless, it could only end to its mercy, having its energy slightly absorbed, as it flew to the surface like a river of white ethereal essence.

"No! My Divine Energy! That was given to me by the Goddess-sama! You punk!"

However, as the glowing orb cried with a slightly mechanical voice, the energy that it had absorbed slowly settled down, as the orb felt a strange connection with the being who had taken over it.

"W-What…? Who… who are you, you damn punk?!" it cried, as it suddenly felt that it had been freed from its altar.

"Fweh? I can move now? Eh?! I can float even!" it said, floating around its chamber, as it used its powers to open the chamber, flying to the surface, where it found the young man behind its suffering!

"There you are! You damn punk! How dare you take over me as if I were an item or something! Do you really realize what you just have done?! Goddess-sama will get pretty angry!"

"E-Eh?! A floating orb?!" asked Frank, as he was surprised over the entity that had just appeared in front of his eyes!

Hades at his side, however, realized who this being was!

"A Dungeon Core?!"
