One Piece: The Strongest Creature

The next morning, Robin and the three sisters woke up very early.

When they finished washing and came to the deck, their Master was already deep into his daily morning training.

Seeing Kahn, as powerful as a monster, practising hard every day, the four maids of Kahn felt admiration and were filled with motivation to practice.

Even if their Master worked so hard, they must not hold back and become a burden to him.

So, Robin and the other three sisters quickly warmed up and started their physical training.

First, they worked on physical fitness, then flexibility. After igniting their bodies, they began practising the Rokushiki Six Styles.

By the way, Hancock had learned two of the Six Styles, which deeply shocked Robin.

These two moves are Iron Body and Paper Arts.

Since Kahn and his group left the Sabaody Archipelago, it has been less than half a month.

It took Hancock less than half a month to learn these two moves. What kind of concept is this?

You know, Robin started practising the Six Styles two years ago, but now she has only mastered one move: Finger Pistol.

In other words, Hancock surpassed Robin's two years of hard work in less than half a month.

Witnessing Hancock's use of Tekkai and Kami-e, she finally understood why Kahn travelled thousands of miles from West Blue to the Sabaody Archipelago to rescue the three Boa sisters.

Hancock's talent is outrageously strong.

In fact, Hancock mastered the two moves so quickly because she took a shortcut.

Among the six styles, Tekkai and Kami-e are semi-finished forms of Armament Haki and Observation Haki.

Hancock mastered Armament Haki and Observation Haki at the age of twelve, making it very easy for her to practice these two Six Styles.

As for the other Six Styles, Hancock can't master them as quickly.

Because her physique is not strong enough.

The ages of the four sisters are as follows: the oldest is Hancock, at twelve years old, then Robin at eleven years old, followed by Sandersonia at ten years old, and Marigold at nine years old.

If they grow up normally, it will take six years at the fastest and ten years at the slowest for the four maids to help Kahn.

At this time, Kahn can't wait.

So, after he planned to get the Logia Rumble Fruit for Hancock, he would help them advance.

It only requires a small price, which can reduce their efforts by several years or even ten years.

At that time, the main force of the Cross family, even if there were only a few of them, should not be underestimated.

...

"It's finally done."

Just when Robin and the others began to practice, Kahn showed a satisfied smile.

Kahn clenched his fist in his right hand, and it was covered with a black substance, visible only after awakening Haki.

This substance is the embodiment of will, necessary for the strong - Armament Haki.

While stroking Hancock's head, Kahn secretly used his natural Observation Haki to read her memory.

From Hancock's memory, Kahn successfully obtained the practice method of Kuja's Haki control.

After imparting the Haki practice method to Robin, Kahn began practising Armament Haki, wanting to complete the last Haki.

It took Kahn only three days from the beginning of the practice to succeed.

This is an incredible speed.

But Kahn felt no pride.

Just like he can't bear the title of the strongest supernova in history, learning Armament Haki in three days is not the fastest in history.

The person who practised Armament Haki the fastest in the original story is the son of the Pirate King and Luffy's foster brother—Portgas D. Ace.

How long did it take Ace to master Armament Haki?

One day.

Yes, just one day.

Awakening Conqueror's Haki at the age of ten and learning Armament Haki in just one day. Ace is an unreasonable talent monster.

Had he not eaten the Logia Mera Mera no Mi and become dependent on elementalization, he would have excelled with pure physical skills and could have followed Garp's path as a Marine. Ace is definitely the most suitable person to inherit Garp's mantle.

Compared to Ace, Kahn's speed is not worth showing off at all. Of course, this is from his perspective. If Hancock knew that Kahn didn't know Armament Haki before this, she would be shocked to see this picture. 

But there's no "if."

Hancock didn't know at all that Kahn came all the way to save them, not only to have them work for him but also for the Haki technique of the Kuja pirates.

...

Not long after Kahn had just mastered Armament Haki, after a night's voyage, their ship finally arrived at Birka Island.

At the end of the cloud path is a gate into Birka Island, similar to the "Paradise Gate" on Angel Island. After passing through the gate, you will find the port of Birka Island.

Mooring their ship at a pier in the port, Kahn and his gang got off the ship. Seeing the arrival of five wingless people from the Blue Sea, the residents of Birka Island, just like the residents of Angel Island, greeted Kahn and his group warmly.

This picture should not be too ironic. If one of them has no wings, they will be despised and bullied. The Blue Sea people who have no wings are regarded as 'fathers' by them.

No wonder Enel couldn't resist destroying this Sky Island after eating the Logia Rumble Fruit. If it were Kahn, who had been bullied for ten or twenty years and suddenly gained almost invincible power, he would take revenge on these people, too.

Knowing why these people were so enthusiastic, the Kahn group bought a local map without changing their expressions, went to the largest hotel on Birka Island, opened the most luxurious suite, and then began to visit this Sky Island.

On the surface, Kahn went shopping with Robin and the three sisters. In fact, Kahn had released his unique perception, looking for Enel's position. Sky Island people without wings are not too hard to find. Moreover, Enel is twenty years old this year and already has the outline of his appearance more than ten years later.

After a while, Kahn, whose perception was large enough to cover several Birka islands, found Enel.

As soon as he found Enel, the corner of Kahn's mouth twitched slightly. He was pretty sure now that Enel hadn't eaten the Logia Thunder Fruit yet.

First, Enel is still outside the city of Birka Island and does not dare to approach crowded places for fear of being bullied by Birka residents.

Second, Enel's aura is not even as strong as the three girls with Robin. A twenty-year-old adult's aura not as strong as that of a teenage girl, or even a nine-year-old girl, means that Enel is a piece of cake.
