The child spent a couple of hours just watching their new environment and collecting new creatures that wandered into their territory.

From this, they gained three fish species and one sea star species. All of these species were predatory in nature. They watched as they entered their territory and hunted the krill, snails, and a few of their fish. Then, they quickly added them to their territory and left them to their hunting.

After a bit more observing, the child decided that they had spent enough time observing and turned to their second floor. The child knew that the people who visited them could come back, and from their reactions, it may not be a positive reaction. So they had to finish creating their second floor. They had everything done except the addition of monsters, and they knew that the monsters would be a key addition to their defence.

Hopefully, I can make more than one type. Thought the child as they stared at all of the species of plants and animals inhabiting the floor.

Three of the species caught their eye, the angel snail, the red trumpet vine, and the long-jawed orb weaver. One water creature, one land creature, and one plant, and if they can make three monster types, they could protect the three different areas of their floor.

The child selected a particularly ravenous angel snail they had watched repeatedly hunt and kill krill that swam around the second floor. They split a small piece of their mana string and rolled it into a tightly condensed ball. Once it was a perfect sphere, the child inserted it into the ravenous angel snail.

The angel started squirming and shaking for a few minutes, and then it began to change. Its gelatinous body grew to fifteen centimetres long and became almost transparent in the water. Its inner organs’ orange and pink colours started to lighten until there was very little colour in them. In the water, the snail became almost invisible, except for the very subtle orange and picky colours the organs gave off. This change in the snail was not the only one.

It gained another wing-life fin, and the two appendage-like tentacles grew longer until they were around seven centimetres long. Then, along the tentacles, the teeth became more ragged and sharp, and the hooks more oversized and more ragged.

To the child, it looked like the hunting properties of the snail were enhanced and made it more of a perfect hunter in the water. Even its core seemed sleeker.

Like with the ice krill, once the child placed the mana core into the angel snail, it became more flat and smooth, seemingly fitting the monster perfectly.

They released the snail monster from their hold and watched as it floated in the current until a whiskered drum swam past it and it attacked.

In a flurry of tentacles, blood, and flesh, the snail started ripping the fish apart and eating it while still alive. The snail consumed every part of the fish before it stilled and began to float with the current.

A blue screen popped up as soon as they watched their snail monster glide and float with the current.

Please register and name your new monster.

Seeing the ravenous nature of the snail staying with the snail even after the transformation, the child decided to call their new monster the “ravenous snail.”

Concerned about their ravenous nature, the child did not overpopulate the rooms with the snail monsters. They were lucky enough that the monsters were too big to go through the tunnels into the other rooms.

With the angel snail made into the ravenous snail monster, the child turned to the next potential monster type on their list, the red trumpet vine.

The red trumpet vine grew along the walls, and most hung toward the water from the ceiling. They had never made a monster species from a plant. The closest they got was the enhancement of the blade seaweed into sharp seaweed, with its leaves being able to cut flesh, but it was not a monster.

They chose a specimen hanging in the middle of the second room, and they chose it for the number of flowers and the size of the vine. It grew the most flowers on the most amount of stems.

Rolling another small mana ball, the child placed it in the plant’s roots, right where the stems grew. Unlike with the ravenous snail, the red trumpet vine did not shake but seemed to contract in on itself. Like the stems were shrinking and contracting back towards the ceiling.

This movement of the vine continued on for about five minutes before the vine began to change. Although not much of the vine visibly changed, it still looked very similar to the other vines hanging from the ceiling. It would take studying to be able to tell the difference, but there were changes. The outside of the stems still looked the same. Still, on the inside of the stem, there was a lot more tissue. There seemed to be almost microscopic hairs growing on the outside of the vine that seemed to connect with the increased tissue.

The flowers themselves had changed along with the increased tissue inside the vines. The flowers on the vines looked exactly the same, but the petals were producing this oil that made this intoxicating smell.

It was strange for the child to smell the flower, as they hadn’t smelled anything before. But the vine’s flowers created a smell that was even intoxicating to them.

For them to think the flowers smell intoxicating, they pondered what this would do to invaders in their dungeon.

It was this smell that allowed them to think of a name for this vine monster. They called it the “alluring vine,” and as they thought this, another registering and naming the monster screen popped up.

They registered their new plant monster, and the child went around the rooms choosing two or three vines to make into monsters before they turned to the spider.

They chose one, made a small sphere from their mana, and placed it into the spider.

As soon as the mana core entered the spider, it exploded, and they received another blue screen.

You have reached the maximum amount of monster types allowed for the first five floors.

Wait, so I’m only allowed these three monsters until the fifth floor?

This new blue screen made them wonder how many monster types they would be allowed with each floor or groups of floors, as the screen indicates. And it made them wish that they had known this as they would have been more careful and considered the creatures they made into monsters.

But what was done was done, and they couldn’t change it now.

As the child moved on, yet another screen popped up.

Congratulations! You have completed your second floor!

Present Creature Species: 12

Present Plant Species: 5

Present Monster Species: 2

With the second floor completed, your sub-dimension will now grow in size.

As their sub-dimension expanded, the child looked out of their iceberg and into the distance.

They scanned the horizon and spotted two ships sailing toward the five islands. On those ships, the child spotted a symbol decorating both of them.
