All Eighteen Years Old
Hancock's words are completely sincere.
After reading the news a few days ago and spending time with him recently, I gradually learned from Robin about the future direction of the "Cross Family". Hancock trains herself every day.
Despite undergoing electrotherapy, no matter how hard she practices, her body won't develop hidden ailments, but it will take at least a few years for Hancock to assist Kahn.
In other sea areas, Hancock, known as the strongest Rumble Fruit user in Logia, could now share the burden for Kahn.
In those regions, Hancock, who can become an element and teleport regardless of obstacles, is the overlord.
In the New World, the strongest sea, Hancock, doesn't have that much advantage.
With her teleportation abilities, Hancock may still be invincible, but there aren't many who can harm her.
There are countless people she can't beat at this stage.
It's like how Momonosuke couldn't harness the power of an artificial Zoan at the age of eight and could only become a loach.
Hancock, who is 12 years old this year, can currently produce lightning up to tens of millions of volts at most, and she can't generate lightning over 100 million volts.
How many volts is natural lightning?
The minimum is 100 million volts.
That means the lightning Hancock currently produces with all her strength isn't as powerful as the weakest natural lightning.
In the New World, there are too many people who can block or even defeat her thunder.
Kahn is someone Hancock feels she must repay in this life. During this time, her dream is to become stronger to help her Master share the burden and earn his appreciation.
After waking up with a smile, Hancock feels both regret and motivation to practice again.
But now, hearing from Kahn that there are Devil Fruits that can exchange life for power surprises Hancock.
As long as one gains great strength, sacrificing the joy of growing up and a bit of lifespan is nothing!
"Master, I am willing too."
"Me too."
Almost immediately after Hancock spoke, Mary also raised her hand.
Robin and Sonia did the same.
The four women showed no hesitation.
Clearly, they've all been transformed into Kahn's loyal followers.
As long as it helps Kahn, a bit of lifespan isn't worth mentioning at all.
Kahn, with his Observation Haki, saw all the inner thoughts of the four girls and felt a sense of accomplishment.
These are the allies he cultivated himself!
Instead of aiming to become the strongest creature in the world, Kahn feels he's more suited to be the world's number one cultivation master.
Feeling proud, Kahn asked with a smile: "Then how old do you want to be?"
"...Eighteen years old!"
The four girls looked at each other, then, as if connected, said the same number in unison.
"It seems we all have a tacit understanding."
Kahn couldn't help giving a thumbs up, grinning: "I think so too."
Eighteen is a very good age.
How good is it?
People at this age are not only teenagers but also young adults, even reaching early adulthood.
At the same time, this age is the number that Kahn concluded after several days of thinking would bring the greatest improvement and benefits to Robin, Hancock, Mary, and Sonia.
In the original story, Hancock also became the Empress of Amazon Lily, the captain of the Kuja Pirates, and the youngest Warlord of the Sea at eighteen.
At that age, Hancock, with her Paramecia-type Mero Mero no Mi and Conqueror's Haki, had a bounty in the New World, definitely reaching the billion-berries level. She was also a top officer and the Emperor's right-hand in the Overlord Pirates.
In this life, although Hancock did not have the powerful Paramecia-type Mero Mero no Mi (Love-Love Fruit), she had consumed the immensely destructive and versatile Logia-type Goro Goro no Mi (Rumble Rumble Fruit), which completely surpasses the Mero Mero no Mi.
After reaching the age of eighteen, even though Hancock lacks an awakened Conqueror's Haki compared to the original story, her overall strength is far greater than her original self.
The same applies to Robin, Mary, and Sonia.
Once they reach the biological age of eighteen, with the Kuja Pirates's method of cultivating Haki, the three girls will soon master Armament Haki and Observation Haki. Their practice of Rokushiki will also become more effective.
After Kahn finds a Devil Fruit for Sonia, she instantly becomes the second strongest among the four women, just below Hancock.
At that point, besides their leader, Kahn, the Cross Family will have two powerhouses.
Cultivate another powerhouse, and Kahn will have the three giants necessary for a powerful pirate crew.
Then, by training some senior officers or even the fourth and fifth giants, in a few years, the Cross Family's strength will far surpass that of the weakest of the Four Emperors, the Beasts Pirates.
Additionally, eighteen is the safest age.
Kahn has the idea of helping Robin, Hancock, Mary, and Sonia age rapidly because he knows the legendary pure gold, which is said to be able to buy the whole world, is real.
And that pure gold is inside a lanternfish.
Once the Cross Family has established itself in the New World, Kahn will go hunting for the lantern fish.
If he can't find it, he will continue looking.
If he still can't find it, Kahn will wait until nineteen years later and ask the main characters of the future to help him.
Nineteen years later, Robin and Hancock will be only thirty-seven years old.
This age is considered the prime of life, an absolute golden age.
Shanks is also thirty-seven years old when the story begins.
Kozuki Oden was only thirty-six years old when he died, and he was in his prime.
Even Shakuyaku, who is sixty-four years old, looks youthful and vibrant.
As long as Robin and Hancock don't overuse their powers like Mary and Sonia did in the original story, thirty-seven will still be the peak of their appearance.
Moreover, the mature temperament at this age will make them incredibly attractive and enviable.
Therefore, eighteen is the best age for Robin, Hancock, Mary, and Sonia.
