One night after the tea party between the ancient dragon grandfather and Ernesto, Tete and I stood in front of the dungeon core.

Now, let's build the biotope-shaped dungeon that Grandpa taught me.

“I'm going to make an island floating in the ocean, and I'm going to grow a lot of delicious things!”

I first set the hierarchical range of the dungeon.

The maximum size of the dungeon hierarchy is five kilometers by five kilometers.

In the middle of it, the rocks and sand from the materials that the dungeon inserted into it were used to shape the outline of the island.

I wonder if the land area ratio is about seven for the sea and three for the land.

"Witch, if the ground is wide, you can plant a lot of fruits!"

For once, I'm going to release sea creatures to breed, so there's a limit to breeding when the area of the ocean is small.

"Mmm... I want to eat some fish, too"

A hybrid of biotope and resource that relies on the world tree to maintain its hierarchy of magic power.

Biotopes include bananas, mangoes, palm trees, cocoa, and sugarcane from tropical fruits, starting with the world's tree.

In addition, grass flowers, which are medicines that only grow in warm environments, are arranged as colonies.

We haven't injected any seawater yet, but we intend to grow edible and medicinal seaweed in the sea, and build rock reefs with large and small rock formations.

"The safety area fountain and the river flowing into the sea are pulled in this direction, and the world tree is planted in the middle of the island... that's it."

A large world tree will be set up in the center of the island's plateau, and a safe zone fountain will be set up at its roots.

Two types of settings may be made for the installation of dungeons.

One is the recovery setting. The other is tolerance for change.

For example, herbaceous habitat, mineral veins, traps, etc., can be mined and mined to reduce the number, and even if the trap is activated or deactivated, the power and magic of the dungeon will compensate for the lost amount - this is the recovery (lipop) setting.

On the other hand, once it is installed, it will not return to its original state afterwards, which is the tolerance of change.

This appears to be used to randomly place treasure chests or to grow or change specific objects.

The big tree of the world that I transplanted from outside the dungeon should grow as it is.

Witch, what are you going to do with this sandy beach space?

"The southern sandy beach is sunny, so I'm going to make it a salt mill."

That said, it is up to the inhabitants to decide whether they will go out of their way to make salt in the dungeon because they are acquiring salt through trade.

It is a means of securing salt trade in the unlikely event that it stops.

"Witch, plant beautiful flowers too!"It's fun to light up! ”

"When you get here, it's a resort development..."

Tete's suggestion is to bloom in the open, and build a wooden bungalow resting place along the coast, and it's a sea house.

It is gradually becoming a tropical resort, but I can't imagine the sight of me playing on this coast without swimming.

Speaking of which, I wonder if I could change into a swimsuit and read a book in the shade.....

Finally, seawater is injected to cover the perimeter of the island, seaweed and coral are planted in the sea, and a simulated life-type water monster is summoned to thin out the creatures that breed in the sea.

Witch, we're almost done!

”That's right... there's nothing wrong with the balance of the dungeon...”

We've created an island hierarchy layout, but the initial creation cost can be created without any problems by using the magic power accumulated in the dungeon core for today.

In addition, the maintenance cost of the hierarchy can be covered at the moment only by the magic power emitted by the world trees and other plants in the dungeon.

"Come on, let's go." Dungeon Core, Hierarchy Creation - Run! "

The dungeon itself rings, the entrance to our dungeon core room disappears, and a staircase to the upper level appears.

Oops, the exit is gone!

Maybe one of the dungeon core rooms shifted down.

The dungeon core room that was on the first floor is on the second floor, and the isolated island created earlier is probably born.

And as I take Tete to the island hierarchy, the world's tree greets me with a pouring simulated sun and a dungeon.

"Witch, it's so hot ~"

Yeah, it's a little hot in the tropics.

While agreeing with Tete, I used magic to protect myself from the sun and heat around me and to look around the island.

Near the staircase that leads down, there is also a staircase that leads to the entrance of the dungeon, from which you can get out.

Also, as I walked around the island, the plants that had been planted were green and fruitful, so I took a taste of them and headed to the seaside, where a wide range of sandy land spread out one step down.

Well, I haven't injected seawater yet, so this is what happens.

In fact, the water of the river overflowing from the plateau of the isolated island above sea level flows into the sand, but due to the homeostasis of the dungeon, the water does not accumulate and disappears.

Dungeon management was done without sea water because it can be done even after hierarchy creation.

Witch, I'm looking forward to it!

Excited about what's coming, I take Tetsu a little further down the sand and set up the [Transfer Gate] on the sand.

Tete, are you ready?

Yes!

Well then, let's go!

Then, as soon as the [Transfer Gate] passage setting was changed, water overflowed vigorously from the mirror-shaped transfer gate.

"Cumming!? That's incredible!"

"Ahhhhh! There's all sorts of things flowing out!"

The sea water flowing in from the [Transfer Gate] flows vigorously into the dungeon and carries various creatures along with it.

Microorganisms, large and small aquatic organisms, sea grasses caught in the water, sand, and lurking in the sand.

Together with them flowing into the sand, I use the power of the dungeon core to cause a change in the dungeon.

Absorbing the injected sea water and replenishing the sea water using it ― Perform!

In the vast sandy area, the sea water gradually fills, and the creatures that flowed into the dungeon spread to the people.

At the same time, it also creates a feeding ground necessary for living organisms such as seaweed that have been taken into the dungeon, and gradually the sea water rises to where we are.

It's a big deal, but once the creature is settled, it's your word!

"I'm glad Grandpa helped me too!"

When thinking about how to breed organisms in the sea of dungeons, it is very time-consuming to sort the organisms to breed and create them while adjusting the balance of the ecosystem.

For this reason, the ancient dragon grandfather cooperated, sank the [transfer gate] that paired with the land close to the climate conditions in the dungeon, and directly injected the sea water mixed with living creatures through the [transfer gate].

"Oh, witch!" The monsters came in with us! "

"Tete, please!"

I was entrusted with it!

As the dungeon gradually fills with seawater, I monitor the dungeon as I move towards the beach.

Then, the water monster that came to the dungeon through the [Transfer Gate] attacked us, so Tete, who pulled out the demon sword, slashed away.

"Yes, the water level has been filled to the intended volume.The wave motion is set to randomly push through a certain range of intensity.Full of tides, it also synchronizes with the movement of the real world.You have placed a Pseudo-Life Monster to protect the Sea of Dungeons.The thinning setting and the order to exterminate the invading monsters are complete... let's keep an eye on the [Transfer Gate] for a while. "

Yes!

The influx of sea water from the [Transfer Gate], which connects the dungeon to the sea in warmer areas, seems to have stopped and the equilibrium has been maintained.

The influx of sea water has stopped, but the creatures can pass unchanged.

If you sink the [Transfer Gate] for a long period of time, some creatures that did not enter when the sea water was flowing in may accidentally enter and settle on the dungeon side.

There was a risk of monsters entering the [Transfer Gate], but the strength of monsters that could enter was largely determined by the size of the Transfer Gate, and I expected that dangerous creatures would also be eliminated by the dungeon's dummy monsters.
