They had this idea to make the rooms into a visible maze. That was why they left chunks of ice in the rooms and hallways.
They will use the ice to create a thinner ice mesh, like their grates on the seventh floor but with narrower bars that will coat the walls and ceiling of the tunnels, with a centimetre or two of space between the wall and the mess.
For the three main rooms, they planned to make mazes of floor-to-ceiling made up of grates. As they made these grates, the child made it so that the ice columns were 30 centimetres thick of pressurized ice.
The bars provided room to see through to other areas of the room but will prevent someone from trying to use these spaces to get into other parts of the maze.
The best part of the rooms is that the child made the space between the grates at most a metre wide and at least 50 centimetres. Their goal with this is to get as much of a maze within a 20-metre-wide room and ensure that the adventurers or invaders will be brushing up against plants and the creatures living within the grates.
Once the grates were all made and a maze was created as best as they could in each room, the child started pulling in sand from the outside to create around ten centimetres of sand on the floor.
Hopefully, this would help make traversing and fighting on the floor more difficult and also help hide any aquatic creatures living in the sand.
With the sand done, they allowed water to flow down from the seventh floor. While most of their floors contained a huge component, water, this floor followed that idea less.
The child watched the water flow into the rooms and halls, and after it reached 70 centimetres, they cut off the flow.
With the basics prepared, the child started creating that overgrown greenhouse effect that they wanted.
Basically, the child grabbed all plants, except for the magma ones, that could grow on the grates. They grabbed around 40 species in total, placed them around the hallways and rooms, and inserted a mana string into all of them.
Once that string was inserted, the child pushed increased growth and reproduction into all of them and watched as the plant life of the floor burst into action.
They watched as slowly the plants invaded empty grates and mesh areas.
The tale has been stolen; if detected on Amazon, report the violation.
After a couple of hours, almost every empty available space was filled with plant life, but it still did not have the desired effect that they wanted.
They could still see into other areas of the maze and did not want that. So the child left the mana string in as they looked at the aquatic plants and corals that would be living in the water.
The child added chunks of floating moss to float around the top of the surface, and they added the aquatic vine and tangled fan grass and eel grass across most portions of the sand.
They also chose four of the smaller species of coral that they could add right beside the grates.
Just as they were about to add the creatures to the floor, the child noticed something coming out of one of the storms.
POV Alexis Miftern
It took a couple of days of him fighting the seasickness before the storm started to dissipate and for the ship to breach onto the Kugluk plateau.
As soon as they breached and the ship's captain, Jamilian, confirmed that this was the plateau they were aiming for, Alexis ran for Mareian, screaming, "We made it!"
"Everything we did was for not!" Cried Alexis, who had prayed that this would work out, that they would survive some of the stormier seas and find the dungeon.
Next, he ran to the boat's bow, grabbed his telescope, and started scanning the horizon.
And just like he had dreamed since the beginning of what Mareian called his ludicrous dream, Alexis found an iceberg that looked just like the iceberg containing the dungeon in the Lost Isles.
"Hey, Christopher! Load two of the dinghies and get your group ready to head to that iceberg." Called Alexis the leader of the four-member cranked adventurer group that his company, the Iceberg Trading Company, hired specifically for this dungeon.
As Christopher and his group prepared for what may lead to a dungeon dive, Alexis got prepared too.
He wasn't just going to spend vast amounts of money, risk it all, and not go with them to see if he had found the still unnamed dungeon.
Grabbing his pack and putting on his runic gloves, Alexis waited for everybody to be ready before they all climbed onto the boats and started rowing to the iceberg as Jamilian and his crew anchored and prepared for long-term anchoring.
It took about thirty minutes of rowing, did they spot a tunnel into the iceberg with an ice platform underneath it. And that practically solidified that this was the dungeon that he had been chasing.
They docked and latched the dinghies to the platform with an iron spike before they climbed out of the boat onto the platform and prepared to enter the tunnel.
As soon as they walked through the tunnel, Christopher stopped, turned to Alexis, and he had a giant smile on his face. "Well, Alexis, this is definitely a dungeon. Now if it's the one you've been chasing remains to be seen. But this right here is definitely a dungeon."
With confirmation that this was a dungeon, everyone became more aware and got weapons out before slowly making their way into the dungeon.
This was all new to Alexis, and it was apparent to the group as they watched him maneuver himself in the tunnel.
Soon, they breached the first floor, and as the group met the first monster, a krill, Alexis felt a massive wave of relief pass through him. One of the monsters of the dungeon in the Lost Isles was a monster krill, and with this dungeon having the same type of monster on the same floor, it confirmed that this was the dungeon he was looking for and would rely on. Even though he was in a dungeon, he found the one that he wanted. He found it!
"It's the one!" He yelled to the group as he threw his hands up and laughed.
"What are you doing, man! You're in a frickin dungeon!" Christopher exclaimed as he looked at Alexis like he was a crazy man.
"I confirmed it! So let's leave, prepare, and then you can do a proper dungeon and collecting dive."
Since Alexis was the adventurer's boss, they followed his directions even though they wanted to stay longer.
They were not alone as the group climbed out of the dungeon and back onto the ice platform.
Seven heads were poking out of the water, staring at them as they exited the dungeon.
