Epic of Summoner: Supreme Summoner System in the Apocalypse

-----

Without wanting to waste another second, I decided to immediately use the Legendary-Grade Dungeon Heart Core.

We rushed into the distance, around some grassy mountains with Kireina and Katrina at my side, as I put the core into the ground and then… filled it with Mana until I got tired of giving it.

We moved away a bit more and waited.

…

…

…

"Nothing is happening, Master…" said Katrina with a disappointed look.

"I am aware…" I sighed.

"Can Gaia tell you anything regarding that?" asked Kireina curiously.

"Patience…" said Gaia.

"She said to wait for it, to have a bit of patience," I said.

"I see…" said Kireina.

"I don't have much patience," said Katrina.

"Geez…"

BOOOM!!!

Suddenly, the entire ground began to tremble as the Dungeon Heart Core started to release circuit-like runes all across the ground around it!

TRUUUUUMMM!!!

The vibrations were incredibly powerful, sending waves of shock all across the ground!

BOOOOM!!!

The Dungeon Heart Core then dived into the ground deep underground!

FLAAAASH!

And then, the entire earth around it began to change, gigantic walls made of bricks started to emerge out of the ground, closing down into a large structure, and even making an entrance and stairs leading down!

Ding!

[You've created a [Dungeon (Legendary-Grade)]!]

[You became the [Dungeon Master]!]

[You've unlocked the [Dungeon Management] System Function]

The large building in front of us was a dungeon. But this was merely the entrance to it as it led downstairs. Meaning that the first floor doesn't have a monster but most likely the one below us has.

Using the amazing Dungeon Management function, I was able to see this Dungeon's status, it was way different than the others in terms of quality and the like.

…

[Dungeon Status: Summoner's Dungeon (Legendary-Rank)]

[Owner: Gustav]

[Assigned Dungeon Core: Legendary-Grade Dungeon Core: #14343]

[Dungeon Rank: Legendary-Grade]

[Dungeon Points Required For Upgrade: 0/10.000.000]

[Dungeon Structure: Labyrinth-type]

[Energy Gathering Efficiency Grade: Legendary] 

[Available Treasure List Grade: Legendary]

[Dungeon Size Grade: Mythical]

[Hastened Monster Multiplication Grade: Mythical]

[Special Abilities: [Greater Monster Multiplication Enhancement: Level 1], [Energy Transmutation: Level 1], [Automatic Dungeon Regeneration: Level 1]

[Dungeon Functions: [Dungeon Manipulation], [Dungeon Transformation], [Dungeon Treasure Creation]

…

There it was! It seems that Dungeon's status is way simpler than I had originally imagined.

All of its stats are at Legendary and Mythical, pretty decent. And it also comes with some Special Abilities and Dungeon Functions…

Also, if I want to upgrade it to the next level, it requires 10 million Dungeon Points, but it has zero as of now.

How do we get Dungeon Points?

Well, there are multiple ways, one of them is letting people die inside so the Dungeon absorbs their essence, bodies, and souls into dungeon points.

Haha… No, I am not doing that one.

Another is to shrug off the monster from the dungeon itself and let the people get inside to kill them so the dungeon and can feed on the monsters' souls and essence to nourish itself and form dungeon points.

Another way to do it is by letting the Dungeon naturally absorb divine energy from the environment, this might take years. Although it seems that the System grade and quality are very high, so its talent is a Legendary Grade and will absorb energy as fast as possible while transmuting it.

In resume, it can do what a normal dungeon can do naturally in years, in just some days.

As of now, after a few hours of waiting leisurely, the Dungeon finally got enough Dungeon Points.

It had gained around 5.000 just in two hours naturally, so I am guessing it will be able to gather even more if I let it sit there. But at some point, this might become slower, so to speed up the process, even more, we do this little trick.

We make monsters!

Using the system, I quickly click the Monster Summon tab of the System, and to my surprise, it is random. It uses whatever points I add and summons a random quantity of monsters of all types, the only thing that is not randomized is the level of strength, which will be Legendary Grade no matter what.

Through this logic, I utilize the Dungeon Points and the first Monsters that are summoned through its Special Ability is an army of blue and black-colored beetles the size of adult dogs.

There were around… a hundred! And they were all Legendary Grade.

I resisted the impulse of killing them to get EXP as I let them swarm the entire dungeon. As they swarmed it, the dungeon itself hasten their growth and reproduction, and the beetles begin to reproduce quickly after a few hours. It is already night, so I decided to leave this for tomorrow.

…

After waking up in the morning, I had a refreshing bath with my two wives which included a lot of… exercise. After that, we had breakfast and we rushed back to the Dungeon.

There, I found that the Dungeon was developing some more, and there were new floors down below, the beetles had infested the area and former one hundred beetles are now thousands… Wow, this is an EXP and item-making machine. This is the only thing that dungeons are, it seems!

I check the System and see that there are over 20k Dungeon points now, from the natural gathering of energies and also because the beetles had begun to kill each other for food.

Using these points, I decided to summon even more random monsters, filling the dungeon even more. This time, there were several giant ants with black armored exoskeletons, venomous and hairy spiders the size of trucks, and a swarm of cube slimes who were way too little yet to be a menace.

The ecosystem of the dungeon continued to develop over time, the next day there were already even more monsters that had reproduced and multiplied, and the day after even more.

After four days of just lazing around and watching over the dungeon, I finally came to the realization that I was having way too much fun with this. So, I decided to finally do something with this growing dungeon, after I summoned even more monsters from it, of course…
