"At worst, I'll just move this entire Otherworld."
Rin's experiment wasn't just about creating a passage connecting two worlds.
The success of this step indicated another of Rin's conjectures.
That was, using the power of the Void God to inversely relocate other Otherworlds to the Cardinal World.
There were many methods.
Like in the Konosuba World, establishing a two-world passage.
Or directly grabbing an entire continent and placing it near the Cardinal World.
Even using a grand summoning spell to make a city descend in a certain corner of the continent.
"Mm."
Violet supported Rin unconditionally.
Even if it meant going to war with the gods of this world, it didn't matter.
"Alright, let's go plan the labyrinth."
Rin and Violet entered the Sealed Cave together.
Before that, Rin set up a cognitive interference barrier at the entrance to prevent adventurers from accidentally entering this area before the labyrinth was completed.
"First, map design."
"Maintain the V-shaped labyrinth structure, setting up a dungeon mode from floor 1 to floor 10, and then back to floor 1."
Rin designed the Sealed Cave not only for Konosuba adventurers, but also to provide an entertainment venue for the citizens of the Monster Nation.
"Only 10 floors?"
Violet said, "The Monster Nation's labyrinth in the original work had as many as 99 floors."
"We have to take it step by step."
Rin's labyrinth was merely an experiment.
Moreover, with the strength of Konosuba adventurers, if it were set to 99 floors, how long would it take them to conquer the labyrinth?
Next, with Violet's assistance, Rin quickly reshaped the internal structure of the Sealed Cave.
One layer after another, continuously descending.
Not only that, Rin also used the authority of time and space to isolate the environment and rules between each layer.
"The first floor's abandoned mine, the second floor's gloomy dense forest, the third floor's desolate plain, the fourth floor's underground waterway, the fifth floor's ruined castle, the sixth floor's undead cemetery, the seventh floor's crystal cave, the eighth floor's lava lake, the ninth floor's flying dragon sacrificial ground, and the final floor's magnificent hall."
Rather than calling it a labyrinth, it was more like ten completely different labyrinths forcibly glued together.
For this, Rin also prepared corresponding final bosses on each floor.
"Monsters and bosses, I'll probably prepare these for now."
In total, Rin designed nearly 500 types of magic monsters, drawing inspiration from many games he had played.
"Next, how to arrange the strength of these magic monsters."
Map planning and monster arrangement were actually not difficult. The real trouble was data balance.
For a good game, numerical issues were crucial.
"Violet, what do you think?"
"It's a bit troublesome."
Violet said, "The strongest combat power in the Konosuba Otherworld, converted to the monster level of the Cardinal World, is only around B-class."
In other words, under fair circumstances, a B-class monster, placed in the Konosuba Otherworld, would be enough to sweep everything.
And although the rules in the labyrinth absorbed the laws from Konosuba, overall, they still leaned more toward the Cardinal World.
"Is that so..."
"Then the strongest magic monster in the labyrinth cannot exceed 6000 magicules."
Rin shook his head. "No, 6000 magicules is still too much."
Not to mention Axel, even if all the adventurers in the entire Otherworld were combined, they wouldn't find anyone capable of rivaling a B-class monster.
Perhaps Princess Alice could barely manage it.
But a kingdom's princess clearly wouldn't personally venture into a dungeon.
"Let's divide them into 100 levels."
Rin said, "Each level corresponds to 30 magicules."
The strongest monster boss in the labyrinth is equivalent to a C-rank combat power of 3000 magicules.
With the power of adventurers, it's certainly impossible to defeat such an opponent.
"But..."
"With the treasures and equipment I've prepared for them, that might not be the case."
Rin created a large number of treasures, materials, and items, and placed them in various corners of the labyrinth in different forms.
Adventurers can find rare items by searching for treasure chests.
They can also pick up drops from monsters after killing them.
They can even mine the labyrinth itself.
For example, the abandoned mine on the first floor genuinely contains ores.
The ores and gems that adventurers dig up and take out are not illusions, but real substances.
Because these things were originally brought by Rin from the Void Universe.
The adventurers' actions are more like exploiting the resources in the Void Universe, which are so abundant in Rin's eyes that they are practically inexhaustible.
For Rin now, he only needs to casually create a planet, and its resources would be enough for adventurers to use for tens of millions of years.
"This should be about right."
After a morning and an afternoon of work, Rin finally completed the preliminary planning of the labyrinth.
Looking at his work, Rin was quite satisfied.
"Next, I'll wait for Rimuru to come back and have her help me test it out."
Thinking this, Rin left the Sealed Cave and returned to the villa.
Just then, Darkness awoke from her slumber.
"You're awake?"
"Rin!"
Opening her eyes, Darkness saw Rin sitting by the bed.
She was about to get up, but the soreness in her body reminded her of everything that happened last night.
For a moment, the girl's cheeks flushed, and she subconsciously pulled up the blanket to cover her eyes.
"Alright, why are you still shy now?"
"You weren't like this last night."
Rin smiled and comforted the girl, who had just experienced intimacy. "Don't worry, I will take responsibility for you."
"Mm."
Hearing Rin's assurance, Darkness finally poked her head out and looked at the man who had taken her first time.
Of course, with Darkness's personality, Rin was destined to be her only one in this life.
The loyal princess knight decided to remain faithful.
"Some things, it's time to tell you."
Rin helped Darkness up, then gently fed her some food before saying, "You've always been very curious about my identity and origin, haven't you?"
Having taken her body, Rin naturally wouldn't let Darkness down.
"Mm."
Darkness nodded. "Rin and Ogerpon don't seem to be from any place I know."
