After relentless effort, Leo had finally succeeded. Using the origin of power he had temporarily borrowed from Doflamingo, he had managed to create a world of his own!
At present, this newly formed world floated in the void, not far from the One Piece universe.
A few days ago, Leo had transferred a fragment of a broken continent from the Pokémon world into his own realm.
Since he himself was the will of this world, he could directly transfer materials from the system into it without expending any of his precious origin power.
His goal was clear—
Once his world grew large and stable enough, he would be able to transfer all the frozen Pokémon creatures stored in the system into this new land.
This was the primary reason for his urgency in creating a world of his own.
However...
At its current state, this world was far too underdeveloped to support such an ambitious plan.
It was still in its infancy, weak and fragile, incapable of sustaining a large population of creatures.
If he were to evaluate it based on the grading scale he had established—
It wouldn't even qualify as an E-level world.
If anything, it was barely an H-level world.
Right now, the entirety of this world consists of nothing more than a single landmass.
Even the vegetation Leo had transferred alongside the continent had withered and died due to the environment's incompatibility.
There was nothing he could do about it.
As the will of the world, he had the ability to maintain a constant temperature, regulate the atmosphere, and even simulate a sun with alternating day and night cycles.
But ultimately, these were nothing more than artificial constructs.
Leo was human—not an omnipotent world-regulating entity.
Unlike the wills of other worlds, he couldn't fine-tune the fundamental laws of nature to ensure complete stability.
At best, he could mimic the mechanics of other worlds and refine his creation through trial and error.
But that didn't bother him.
He hadn't expected perfection.
In fact, the rapid progress he had made was already beyond his expectations.
At the very least, his world had reached the point where certain plants could survive.
And in the end—this wasn't a world meant for the weak.
A harsh environment?
Good.
It would only push the inhabitants of this world to evolve and grow stronger.
And there was no species better suited for this world than the Chimera Ants.
Individually powerful, highly adaptable, and possessing an astonishing reproductive rate.
More importantly—
Because Chimera Ants reproduce by consuming other organisms, Leo felt no guilt in using them for his experiments.
Furthermore, all offspring were biologically bound to obey the Queen's commands.
Even if ordered to die, they wouldn't hesitate for a moment.
A race this perfect—he would be a fool to pass up such an opportunity.
With that decision made, Leo spent the next week conducting various experiments on the Chimera Ants.
At the end of it all, he arrived at a conclusion that was both surprising and disappointing.
The surprising part—
The Chimera Ant Queen was indeed capable of breeding worker ants that could inherit multiple Devil Fruit abilities.
The disappointing part—
Each Chimera Ant could only possess one ability from each Devil Fruit category.
In other words—
A single Chimera Ant could have:
One Zoan abilityOne Paramecia abilityOne Logia ability
However, due to conflicts in genetic expression, while all three abilities existed within the same individual, only one could be actively used at any given time.
Of course, there were rare cases where genetic anomalies resulted in Chimera Ants that could only utilize one Devil Fruit power, despite having the potential for others.
With the right guidance, these particular ants could be trained to access their latent abilities—allowing them to switch between powers.
But in the grand scheme of things, these findings didn't affect Leo's plans.
So he didn't dwell on them.
In The Celestial Island.
Leo gazed at the countless Chimera Ants before him, each unique in form and power.
A satisfied smile spread across his face.
His experiment was a success.
The first true residents of his new world… had arrived.
Without delay, Leo turned his gaze to the Chimera Ant Queen kneeling before him. His voice rang out with commanding authority:
"From today onward, your race shall be known as the Zerg!"
"And you... you shall be the Queen of the Zerg—Sarah La Kerrigan!"
"Thank you, my Lord, for bestowing this name!"
The newly named Zerg Queen, Sarah, bowed her head respectfully, her gem-like black eyes gleaming with joy.
Leo continued,
"Next, I will send your Zerg brood into my world."
"That world is neither strong enough nor vast enough yet."
"I need greater power to support its growth and stabilize its foundations."
Facing the Zerg, now bound to his will, Leo saw no need for pretense or excuses. He laid his intentions bare.
The world, after all, could evolve independently.
So long as the beings inhabiting it grew in strength, the barriers of this world would thicken, and the light and shadows in the surrounding void would expand.
Leo's aim in enhancing the Chimera Ants and renaming them as the Zerg was to leverage their unique attributes, hastening the stabilization of his newly created world.
The ranking of a world depended on three factors: the expanse of its real space, the population of its inhabitants, and the power levels of its denizens.
The higher these factors climbed, the more stable and promising the world became.
While Leo could freely manipulate the population and strength of the creatures, the expansion of real space occurred naturally and remained beyond his direct control.
Real space referred to the actual habitable regions of the world, independent of the rules dictated by the world's will.
Take the world of Detective Conan, for instance—though it introduced a boundless universe with potentially countless mysterious life forms...
In reality, its livable space was limited to an area no larger than Earth, keeping its world rating relatively low.
Leo's strategy was to expand the real space by increasing the number and power of its inhabitants.
There were numerous methods to achieve this—discovering other planets within the universe, unlocking vast secret realms or reverse worlds, or directly enlarging the world's boundaries...
His observations of the One Piece world had already proven the viability of this approach.
The basic combat capabilities of Zerg soldiers, each wielding triple Devil Fruit powers, had already reached Level 60.
With the introduction of ninjutsu, magic, Haki, and other power systems into this new world...
The growing numbers and increasing strength of the Zerg would naturally stretch the boundaries of real space.
In doing so, the new world could mature rapidly, evolving into a vast domain without the need for millennia of gradual development.
"Go forth! Multiply and thrive in the new world!"
With a casual wave, Leo summoned a colossal portal of time and space before Sarah and the gathered swarm.
"I shall follow the will of the god!"
Sarah didn't hesitate or question Leo's intentions. Rising to her feet, she led the swarm through the portal and into the new world.
Once all the Zerg had crossed into their new realm, Leo teleported to the depths of the Windless Zone's ocean.
After countless years of exploration, these waters had proven to be a treasure trove of hidden riches and home to the immense Sea Kings.
Some of these behemoths stretched over 5,000 meters in length!
With a mere thought, Leo seized control of countless Sea King species, holding them firmly in his grasp.
Spending a measure of his power of Origin, he hurled these aquatic giants into the new world.
Each titanic Sea King had a Devil Fruit forcibly crammed into its maw!
Leo had even altered parts of the New World to create an environment perfect for deep-sea life.
And due to the unique laws of this new realm, the waters there posed no threat to Devil Fruit users.
Having completed his preparations, Leo sealed the gateway to the new world, ceasing his observations.
From this point forward, the new world drifting within the void would operate under a vastly different flow of time than the One Piece world.
Since Leo himself had crafted the new world's temporal laws, he had absolute control over its time flow.
Of course, this manipulation demanded some expenditure of original power.
Under Leo's careful calibration, the time differential between the New World and the One Piece world became staggering—
For every single day in the One Piece world, five years would pass within the New World!
Upon arriving in the void zone, Leo could see with the naked eye that the new world was continuously expanding.
Perhaps it wouldn't be long before he could place a second continent within it.
In the blink of an eye.
Another month had passed.
Even after setting the new world on its course, Leo didn't allow himself to grow complacent.
He quickly initiated a second round of open recruitment in the One Piece world!
The hatch of the Hyperbolic Time Chamber opened, and four newly appointed Dimensional Merchants stepped forward.
Usopp, Perona, Smoker, Trafalgar Law...
These four had successfully passed the tests and interviews, earning their place in the next wave of Dimensional Merchants.
Meanwhile, the war in the One Piece world had reached its conclusion.
The Revolutionary Army, fighting in the name of justice, had claimed an overwhelming victory. They had successfully seized Mariejois and were now convening on the Red Line to establish a new world government and implement their policies.
However, the original World Government had not been completely eradicated.
Perhaps foreseeing their downfall, the Five Elders had sought an opportunity for survival.
In the end, they betrayed Imu, surrendering him to the Revolutionary Army for trial. In return, they abandoned their hold over the One Piece world. With Leo's approval, they transitioned into their new role as agents of the Transdimensional Chamber of Commerce.
From this day forward, the Celestial Dragons would no longer meddle in worldly affairs. Instead, they had been relegated to the service industry, now working in Pokémon Centers scattered across the world.
Leo did not strip them of their signature attire; rather, he had them don white space suits and bubble helmets before assuming their new positions.
As for whether the once-arrogant and domineering Celestial Dragons could truly serve others?
The Five Elders weren't fools.
Those among the Celestial Dragons with excessive criminal records or an irredeemable mindset had already been dealt with in secret.
The ones that remained were intelligent survivors—individuals who understood what it took to adapt and endure.
For Leo, the One Piece world had now served its purpose.
All that remained was to continue selecting its most outstanding individuals and recruit them into his ever-growing Transdimensional Chamber of Commerce.
"Go! Complete your internship missions and become the backbone of the Chamber of Commerce!"
Leo's words rang out once more.
Excitement and anticipation shone in the eyes of the four new Dimensional Merchants as they stepped one by one through the shimmering portals of time and space.
But Leo's gaze had already shifted—
To the new world beyond the void.
"I wonder how Sarah and the Zerg are progressing..."
With a mere thought, his divine perception locked onto the new world.
As its creator, Leo possessed an absolute God's perspective.
When he observed the new world, it was as though he were gazing at a massive sandbox.
His focus soon fell upon a city on the mainland.
Originally, this city had been part of the Pokémon world, once boasting breathtaking scenery and vibrant landscapes.
But in the worldview of the Zerg, aesthetics held no meaning.
Now, the city lay in ruin—scarred by battle, its beauty reduced to mere remnants of the past.
Training grounds had replaced the towns, one after another.
Across the city, countless Zerg of varying forms and sizes were undergoing rigorous combat training under the watchful eyes of their instructors.
They didn't understand why they were training.
But under Queen Sarah's command, their purpose had been imprinted deep within their very instincts—
To grow stronger.
Through his divine sight, Leo observed that after more than a hundred years of development, the Zerg had successfully spread across the world.
The Sea King species he had released into the new world had been devoured—picked apart by the Zerg—infusing their genes into the swarm and furthering their evolution.
Yet, the Zerg were not the only ones thriving.
Other creatures had emerged as well—descendants of Sea King species that had once possessed amphibious abilities. Upon reaching land, they had multiplied and evolved into entirely new life forms.
This was no accident.
Leo had deliberately altered Sarah's instincts, shifting her from her original, mindless predatory nature.
Rather than wiping out entire species through unchecked consumption, she had learned a new strategy—one akin to sustainable hunting.
By adopting a controlled predation approach, the Zerg could continue feeding while ensuring the survival of other species, allowing for a stable ecosystem.
As a result, the new world now teemed with life—both on land and in the depths of the sea.
Even in the ocean's darkest trenches, a handful of Devil Fruit-powered Sea Kings had managed to escape the Zerg's grasp, evading capture.
Sea Kings have an extremely long lifespan; a mere hundred years or so is nothing to them.
These Sea Kings are either powerful enough to fight against the entire Zerg, or they are good at hiding and have not been discovered by the Zerg.
And,
Leo also discovered that these Sea Kings seemed to be influenced by the Zerg, and even had the intention of sticking together for warmth.
Relying on their wisdom that is no less than that of humans, they actually established a sea clan deep in the sea with the purpose of overthrowing the rule of the Zerg.
He has to say.
The development process of life is always full of various surprises.
