One Piece: The Strongest Creature

Blueno, who doesn't have Observation Haki, is like a lamb to the slaughter in front of Perfect One, who can hide.

If it weren't for the fear that Blueno might use the ability of the Door-Door Fruit, a Paramecia-type, to escape into another space, Kahn wouldn't have even bothered giving Perfect One the order to assassinate him quietly. He would've had a Perfect One deal with Blueno out in the open.

However, the smooth assassination by Perfect One shows just how impressive Invisible Black's abilities really are.

It's already frustrating when a weak person can turn invisible. But when someone strong can go invisible, it's a nightmare for people with poor perception.

For example, Sanji, who wore the Raid Suit in the original story, and Queen, who also mastered the Germa 66 technology, are such cases.

After killing Blueno, Perfect One, standing several meters tall, took Blueno's body and merged back into the darkness.

Soon, the perfect mother and daughter will be standing in front of Kahn's group, who are staying at the Center Street Hotel.

"Carina, go ahead."

Looking at the corpse before him, Kahn spoke to Carina, who was startled by Perfect One and the body's sudden appearance, as she hadn't mastered Observation Haki yet.

"...Understood, Master."

Carina, whose nerves were stronger than most, quickly regained her composure, picked up a fruit provided by the hotel, and began the ritual for snatching abilities.

Soon, as a thick black mist dispersed, a Devil Fruit with a unique spiral pattern appeared in Carina's hands.

"Master, what's the ability of this Devil Fruit?" Nami, standing behind Kahn in a black and white maid outfit while massaging his shoulders, asked curiously.

"This Devil Fruit is specially prepared for Nojiko," Kahn said, taking the Devil Fruit from Carina and explaining, "It's a Paramecia-type, and its full name is the Door-Door Fruit."

"As the name implies, the person who eats this Devil Fruit can open doors on any object, whether it's inorganic, organic, or even air itself."

"Most notably, the air door connects to what's called a different space."

"As long as the user hides in that space unless someone has the ability to access it, even I can't touch the person with this Paramecia ability."

"LET..."

Hearing Kahn's words, Carina and Nami, no longer naive to the world, couldn't help but gasp.

Carina, who had studied the "Devil Fruit Encyclopedia," especially stared in awe at the Door-Door Fruit in Kahn's hand, exclaiming, "This is one of the Paramecia-type rule-breaking fruits."

"Good." Kahn nodded with a smile. "This Devil Fruit's ability is quite tricky to understand, but its combat power is pretty average. It's perfect for Nojiko, who isn't fond of fighting."

"With the Door-Door Fruit's ability, things will be much more convenient for us moving forward."

Since Carina and Nami were still young, they were only assistants to Robin and Sonia for now, and Kahn didn't mention that the Door-Door Fruit was actually a new strategic-level ability for the family.

This was the main reason Kahn had targeted the Paramecia Fruit.

Walking through different spaces has an effect similar to teleportation, which is the strongest aspect of Door-Door Fruit.

During this space transmission, no one can see what's happening in the other space, not even those with Observation Haki or the ability to foresee the future.

This ability is perfect for gathering intelligence and sneaking into specific locations.

Especially for infiltration.

With this power, Kahn could even attempt to break into the deep-sea prison known as Impel Down, often regarded as impenetrable.

For others, the prison is a place of no escape, one of the most dangerous spots in the world.

But for Kahn, Impel Down is a massive treasure trove.

Particularly in Level 6, Eternal Hell, where every prisoner has a bounty of over 100 million berries.

Many legendary figures and notorious pirates who roamed the Grand Line are imprisoned there.

For example, one of the Four Legends from the previous era was the only one to defeat Fleet Admiral "Redfield" Patrick Redfield.

Douglas Bullet, a former member of the Roger Pirates, was already a major force when Shanks and Buggy were still apprentices.

It is also Byrnndi World, which wields the Paramecia-type More-More Fruit, among others.

With Carina and Kahn, who possess the powers of the Logia-type Dark-Dark Fruit, all they need to do is sneak into Impel Down's sixth level. The prisoners, bound in Seastone cuffs, are nothing more than helpless targets before some of the strongest creatures in the world.

As long as Kahn sneaks in, he could easily take the powers of those with Devil Fruit abilities.

However, Kahn was more interested in their bloodline factors than their Devil Fruit powers.

The perfect creation, a fusion of Kaido's and Bell's bloodline factors, is already incredibly strong.

If Bell's bloodline is combined with that of the Red Earl, could Kahn create a perfect being capable of inheriting natural Observation Haki?

If his androids could wield Haki, it would be a groundbreaking achievement.

Even without Haki, such creations would still rival, or perhaps only slightly fall behind Perfect One.

Therefore, after securing the Door-Door Fruit, Kahn no longer needs to hunt powerful people everywhere. Instead, he can quietly continue building his family's strength without drawing attention.

Carina and Nami didn't know that Kahn had gone after the Door-Door Fruit with this plan in mind.

Carina was fascinated to see a Paramecia-type rule-breaking Devil Fruit for the first time.

Meanwhile, Nami was filled with emotion.

In a world where slavery is still rampant, the division between master and servant is very clear.

A servant remains a servant, always considered low and humble.

Their status isn't even on par with ordinary citizens.

If you're a servant to the nobles or the rich, unless you encounter someone kind, you have no rights. Even if you were killed for no reason, the Marines wouldn't bother arresting the killer.

But Nami knew she had the best master in the entire world.

Not only did he give her the power to take revenge, but he also fulfilled all of her desires. After learning about her love for money, he gave her half of the famed Golden City without a second thought.

The only reason he didn't give her the entire city was that he worried she wouldn't be able to hold onto it, so he asked Sonia to assist her until she mastered the Gold-Gold Fruit.

And now, he was hunting for a rare and powerful Devil Fruit ability just because his sister didn't like fighting.

How could Nami not be moved by this?

If she weren't only fourteen years old, with her appearance and figure not yet fully developed, she wouldn't even be qualified to carry Mary's shoes, let alone be on the same level as Hancock or Robin.

But without a doubt, Nami's heart was already beginning to shape itself in Kahn's image.
