After pulling the iceberg into their domain and finding nothing, the child kept the little iceberg in their domain and fully claimed it. It was ten metres high and five metres wide, and the child wanted to keep it.

Not wanting to leave it in the water, the child cut the iceberg into two, netted the two pieces with their mana strings and lifted them up out of the water. Carefully, they lifted them to the top-flat portion of their iceberg and placed the pieces on the ice. With the ice pieces resting on their iceberg, the child took the ice pieces and condensed them into pressurized ice pieces. As they condensed the ice, the child carefully kept the original shape that the ice once had as an iceberg.

Once both ice pieces were fully converted into pressurized ice, the child lifted them up with the flat piece where they originally cut the iceberg; that was where they attached the pressurized ice columns to their iceberg with the larger ice mana string. When they were finished, their iceberg now had two ice columns sticking out of the top of the iceberg close to the centre of their iceberg, but not too close.

The larger of the two columns was six metres tall, and the other was four metres, and both had sharp corners, ledges, and pointed peaks.

Seeing how much they have been using their ice mana strings, the child split them multiple times, took two of them and started directing ice growth along the base of these columns up to make them stronger and thicker. As the ice mana strings worked, the child made about a metre deep and 50 centimetres wide of the iceberg into pressurized ice to ensure that the ice columns were fully attached and would be okay if there was any bad weather.

Taking another two ice mana strings, the child directed them to fill out the indents that the creation of pressurized ice made.

They watched carefully as the ice mana strings filled the ice columns back to the way they originally were and became more peak-like and filled in the indents before they stopped the ice mana strings and let them flow back into circulation.

Once the columns were finished, the child turned their attention back to their first floor. As they stared at all of the living beings within the floor, the child felt a little nudge at the back of their head to take one of the creatures or plants and create a dense knot of their mana inside them.

Carefully looking at every living being home to the first floor, the child decided to use one of the krill species to do this with. But which one?

The flow krill are the fattest swimmers, and the shield krill had thicker and stronger shells. But the frozen krill are just more interesting, with the ice crystal growths on an additional two legs.

If you discover this narrative on Amazon, be aware that it has been stolen. Please report the violation.

The child chose a frozen krill to create a knot of their mana in.

With a single frozen krill in front of them, the child cut a five-centimetre-long string out of their mana circulation and started rolling the very edge of the mana string in their palm. As they rolled the mana string into a ball, the mana string got thicker and denser, turning into a solid object. The child continued rolling the mana ball in their palm until it was three millimetres in size.

Carefully, using another mana string, they placed the mana ball into the area right above the tail of the krill and sewed it into the krill. The moment the mana ball was sewn into the krill, the krill started to rapidly grow and change.

The krill grew until it was ten centimetres long, and this was not the only change the krill had. Unlike the original frozen krill, where only two legs had ice crystals growing on them, almost the whole body had at least some ice crystals growing off it. Along with the ice growth, the shell of the krill gained an icy defence to it. The whole krill was now a light blue colour.

With the growth of the krill, the mana ball grew bigger and more ragged than it had initially been. Instead, the ball had become more ragged looking, a lot less smooth, but it seemed to suit the krill. The ball had also grown to one centimetre.

As the child was studying this new krill, a blue screen popped up in front of them.

Congratulations! You have made your first dungeon monster!

…what are dungeon monsters? As they asked this question, another two blue screens popped up.

Monsters are beings that have evolved through mana and have a mana core. The size and density of the mana core can differ by the individual monster’s power.

The child was quite surprised at what the screen said.

So by making that mana ball, no, mana core, I created a monster?

With wonderment about their creation, they turned their attention to the second blue screen.

Please name your monster and register it to your dungeon.

They stared at the screen and at their monster krill, trying to think of a name. So far, they have been naming everything mostly on their characteristics, and they decided to continue this naming sense with their first monster.

The monster will be called “ice krill.”

The name “ice krill” has been registered with the system in accordance with the type of monster.

You are now able to re-create this monster type by creating mana cores and inserting the mana core into the original species or letting them naturally reproduce. Monsters can only be created or bred within your floors, and the number of monsters created or bred depends on floor size.

As soon as they read that they could make more ice krill, the child went to work creating an additional five ice krill. Though it did not exactly go to plan.

The creation of the mana cores went quickly, but once they started placing the cores into the frozen krill, half of the time, the mana cores were too much of a shock to the frozen krill system, and it killed them. The child took the mana cores out of the dead krill and kept on trying.

It worked about half of the time, and in the end, the child had six new ice krill monsters.

As the krill monsters started paring up, another blue screen popped up.

Congratulations! You have completed your first floor!

Present Creature Species: 7

Present Plant Species: 2

Present Monster Species: 1

Due to the completion of the first floor, the sub-dimension size will expand.

Just as the child finished reading the screen, they felt their skin tighten slightly as the sub-dimension grew.
