After explaining his idea in full, Izumi looked calmly at the two before him.
Meanwhile, Alaya and Gaia stood frozen, their expressions filled with confusion.
"Will that really work?"
"And… are you sure it won't be dangerous?"
"If we send out invitations like that… wouldn't it be the same as exposing our world's coordinates?"
"What if powerful beings intercept them… and come attacking us directly?"
Alaya voiced her concerns without hesitation. This was exactly what worried her the most.
Connecting with other worlds certainly had its benefits—but it also came with risks.
If those invitations fell into the wrong hands…
Wouldn't they be inviting disaster upon themselves?
Hearing this, Izumi simply smiled and shook his head.
"No need to worry."
"These invitations won't reveal our world's coordinates."
"They're more like keys—keys that open a door and allow others to enter."
He paused, a faint smirk forming at the corner of his lips.
"And once they step into my world…"
"Do you really think I'd be afraid?"
There was absolute confidence in his voice.
The true strength of this world wasn't just its adaptability, nor its limitless growth potential.
It was something far more overwhelming.
Within this world, Izumi was invincible.
And now, with three Simulation Genesis Diagrams at his disposal, if he were to go all out—
Even those ranked among the highest tiers… he could still challenge them head-on.
But beings at that level?
There were barely any in the entire multiverse.
Realizing this, Alaya and Gaia suddenly lit up with understanding.
"Right…!"
"In this world, you're unbeatable!"
The tension in the air dissipated instantly.
With renewed confidence, they looked at Izumi.
"Then what should we do?"
"Is there anything we need to prepare?"
Izumi nodded, his tone turning practical.
"What you need to do is simple."
"Work together with Asagi and build a complete trading system."
"Create a platform where we can acquire valuable items from other worlds."
"You can set up appraisal services, or allow individuals to trade freely."
"We'll collect what we want… and in exchange, give them a universal currency used in our world."
"With that currency, they can purchase anything here."
"Abilities, items, knowledge… anything that can be traded—we sell it."
"Our goal is simple."
"To obtain rare and valuable things from other worlds."
He continued, laying out his ideas one after another without pause.
"We can even build a commercial city."
"Visitors from other worlds will be gathered there."
"Our people can sell goods within it."
"And if residents from newly integrated worlds want to sell something…"
"You can step in and directly extract their abilities."
…
Izumi's vision flowed endlessly—covering trade systems, currency structures, operational rules, and more.
Alaya and Gaia listened intently, committing every detail to memory while simultaneously calculating feasibility.
Before long, they reached a conclusion.
Everything Izumi described…
Was completely achievable.
Extracting abilities, constructing trade systems—within this world, all of it could be done with ease.
The two exchanged glances before nodding firmly.
"It's doable."
"Give us a few days, and we'll have everything ready."
"Leave it to us!"
"You just focus on building the trading city, Izumi-sama!"
Hearing that, Izumi nodded in satisfaction.
"Good."
"Then get to work."
"Don't worry about adjusting the world's rules a little—as long as the core remains intact."
"Understood!"
With that, Alaya and Gaia vanished instantly, heading off to consult with Asagi Aiba.
...
Left alone, Izumi fell into thought.
"A commercial city, huh…"
"What kind of style should I go for?"
"A traditional fantasy city? …Hmm."
He shook his head.
"That doesn't quite fit."
After all, this was a world where countless anime-style civilizations coexisted.
A sudden shift into a purely classical cultivation aesthetic would feel out of place.
Looking over the cities already present in his world, Izumi quickly made his decision.
With a snap of his fingers—
Reality shifted.
Centered around the Kabbalah Tree of Life, the upper and lower layers of the world began to stretch apart, increasing the distance between them.
Then—
At the midpoint between the two layers—
A massive ring of light appeared.
Moments later, futuristic circular cities materialized one after another, surrounding the Tree of Life completely.
Brilliant pathways extended throughout the structures, with numerous routes leading upward into the higher layer.
The entire region radiated a sleek, sci-fi aesthetic.
The moment it appeared, it drew countless gazes.
Elsewhere—
A golden-haired king tossed aside the battered figure he had just been beating.
"Hmm?"
"What interesting toy has appeared now?"
It was none other than Gilgamesh.
A grin spread across his face.
"This world just keeps getting more entertaining."
Since integrating into this world, his days had been nothing short of delightful.
He would spar with that stubborn hound, beat him senseless, share drinks with like-minded individuals, and wander through different regions.
Compared to the monotony of the Throne of Heroes—
This was paradise.
And he wasn't the only one who noticed.
Many others turned their attention toward the newly appeared city.
Though no one knew what Izumi was planning—
They weren't particularly concerned.
After all…
He would explain it eventually.
Besides, the newly opened pathways connecting the upper and lower layers suggested that this place might soon become important to everyone.
...
As for Izumi—
He paid no mind to the attention.
After finishing the city's construction, he nodded in satisfaction.
"Now… time to set the rules."
Within this city—
Combat was forbidden. Violence was prohibited.
Of course, it wasn't absolute.
Special zones were designated for those who wished to fight.
At the same time, he divided the city into multiple districts:
- Commercial Zones
- Entertainment Areas
- Combat Arenas
Everything was neatly organized.
Once that was done, Izumi began assigning roles.
After all, many of the girls in his world didn't have much to do.
Letting them earn a bit of extra income here seemed like a great idea.
A mischievous smile appeared on his face.
Without warning—
He pulled a girl into his arms.
The girl blinked in surprise.
"…Izumi-sama."
It was Enju Aihara.
She sighed helplessly.
"Could you please stop doing that?"
"Suddenly pulling me over like this is really startling…"
"You could at least warn me first."
Her tone carried a hint of complaint—but also familiarity.
Clearly…
This wasn't the first time Izumi had done something like this.
