One Piece: Trainers on the Straw Hat Pirates

And this wouldn't have been possible without the help of the fish-men, who are able to move freely in the ocean.

To this end, Joy Boy made a vow with the Fish-Men, promising that once everything was stable, he would allow them to have their own territory on land and establish their own kingdom.

And so, the world gradually settled down.

Countries that survived the disaster have begun to gradually carry out post-disaster reconstruction and planning.

This time, without the Lunaria tribe oppressing them and constantly demanding slaves and supplies, the development of various countries can be described as rapid and leapfrog.

With the support of the Twenty Kings, Joy Boy established a new and enormous kingdom on the foundation of the Lunaria God Kingdom, and acquired many advanced technologies from the Lunaria.

However, Joy Boy's purpose in overthrowing the rule of the Lunaria was never to make himself superior, so he never thought of becoming a great king.

After several attempts to decline, Joy Boy and the Twentieth King made a pact...

He will become the leader of this vast kingdom, but not as a king.

At Joy Boy's suggestion, the Twenty Kingdoms were tasked with creating a "Void Throne" for him.

This void throne will represent Joy Boy's identity, but he will not actually sit on the throne.

At the same time, Joy Boy asked the twenty kings to leave their weapons here, which on the one hand represented the sealing of Joy Boy, the only one qualified to unify the world, and on the other hand represented that there would be no more wars between kingdoms, so that peace would last forever.

The moment the Void Kingdom was completed, Joyboy led the Twenty Kings in making a vow that all nations would be equal and that no one would ever harbor thoughts of dictatorship.

However, what Joy Boy was unaware of was...

Just as they were making their vows, a cold glint suddenly flashed in one of their eyes.

And this person's identity is not simple either.

He is a descendant of the person who touched the taboo of the sun in ancient times and caused the solar crystallization riot!

In fact, the violent event of the sun crystallization was a coincidence.

Although the ancient Lunaria were naive, they were not so foolish as to believe everyone.

Therefore, they made a vow in the Sun Crystal early on that only those with lunar bloodlines are qualified to use the power of the Sun Crystal!

At that time, the greedy human from Earth had also learned of this oath from the Lunaria race.

So at that time, he had abducted a Lunaria child and used his bloodline to activate the Sun Crystal in an attempt to obtain its power.

But what he didn't expect was...

The oath of the crystallized sun is a concept!

Even if he activated the Sun Crystal with the blood of the Lunaria race, it still wouldn't do as he wished once the Sun Crystal detected that he was the true user.

However, the already triggered solar crystallization could not be stopped, which caused the solar crystallization to riot.

It can only be said that those who are able to accomplish great things in every era, whether they are good or bad, possess intellect and fortune far exceeding that of ordinary people.

Although the greedy humans of Earth failed to obtain the power within the Sun Crystal and fulfill their ambitions, they did successfully utilize the willpower emanating from the Sun Crystal to add a layer of covenant to their bloodline…

His bloodline will be the same as the lunar bloodline, allowing him to use the power of solar crystals.

He firmly believed that since he had appeared in this era, one day in the future, his bloodline would eventually take his place and fulfill his ambition to control the sun!

And so, amidst the fury of the Lunaria tribe, he met his death, but left all hope for his descendants.

His name is no longer that important.

However, his surname was fortunately preserved during the subsequent turmoil, and he became one of the twenty kings who overthrew the rule of the Lunaria race!

At that moment, the name of the person swearing an oath while looking at Joey Boy's back was...

Narona Im!!!

Peace has truly arrived.

After taking the oath, Joy Boy naturally became the leader of the Great Kingdom.

The twenty kings who had accomplished the feat of overthrowing the previous dynasty returned to their respective countries and began to develop their national military.

However, as the saying goes, human desires never disappear.

Although Joy Boy had assured the Twentieth King that he would never have any dictatorial intentions and would not follow the old path of the Lunaria.

But you can't see into someone's heart.

No one can guarantee that what Joy Boy said is his true inner thought, or that his thoughts will never change.

The twenty royal families were not merely subservient to Joy Boy's power, but rather to his will.

At first, everything was as peaceful and serene as it appeared on the surface.

In the years following the founding of the Great Kingdom, Joy Boy worked tirelessly, fulfilling the promises he had made before the war.

He first used the technology left behind by the Kingdom of Gods to request the best shipwrights in Water Seven to build a huge, black warship.

Their warships' cannon fire could destroy a powerful kingdom in an instant!

Of course, artillery fire was merely a byproduct of the blueprints.

Joy Boy's true idea was to use the warship's terrifying maneuverability to allow people to cross the ocean and rebuild the bonds that existed between the world and the sea before it was swallowed up.

Similarly, he found a powerful flight device in the realm of the gods that could only be activated using solar crystals.

Unfortunately, due to the final decision of the Lunaria God-King, there is not much energy left in the Sun Crystal, which is far from meeting the requirements for using this flight device multiple times.

Otherwise, its power alone would be enough to provide Joy Boy with even more help.

Time passed slowly.

The enormous kingdom that inherited the legacy of the Kingdom of God is growing at a rate far more terrifying than anyone could have imagined!

Under Joy Boy's leadership, the Great Kingdom not only completed its infrastructure construction, but also, through his delegation of authority, transformed technologies that the Lunaria people had not previously widely utilized into civilian technologies, enabling the people to enjoy a happy life.

At the same time, Joy Boy also sent out invitations to races all over the world.

As long as people are willing to come, the great kingdom will surely have a place for them.

Under the influence of various policies, the Great Kingdom developed comprehensively in terms of population, technology, military and other aspects, and soon surpassed the God Kingdom that was previously dominated by the Lunaria race.

At the same time, many powerful races and nations around the world also share a deep friendship with Joy Boy.

For example, Wano Country, where a seastone mine was unexpectedly discovered after a disaster, and the Ryugu Kingdom, which can move freely in the ocean and unleash powerful strength.

The former can limit the power of the vast majority of strong individuals in this world, including the Twenty Kings!

The latter has a unique advantage in this world that has been swallowed by the sea, and is a force that no one dares to underestimate.

Moreover, the mermaid rulers of the Dragon Palace Kingdom possess terrifying power to command the Sea Kings.

If, at the very beginning of the Great Kingdom, Joy Boy was merely the world leader elected by the Twenty Kings...

After all the turmoil, Joy Boy, with his own strength, the power of his country, and numerous allies, is now rightfully entitled to be called a "world leader."

This is something the Twenty Kings do not want to see!

They are willing to acknowledge their choices, but may not be able to accept a true "leader".

And so, for the first time, a rift appeared between the Twentieth King and Joy Boy.

Joy Boy, who was busy transferring the Ryugu Kingdom and Fishman Island from the deep sea to the land at the time, was completely unaware of this!

After his failed attempt to float the entire island from the seabed using giant soap bubbles, Joy Boy came up with another idea...

They built a giant ark, filled it with the entire situation on Fishman Island, and then had a giant sea king pilot it to the surface.

This plan was incredibly stupid.

But it was the last and most practical solution that Joy Boy and the Little Mermaid at the time came up with, and one that had absolutely no chance of failure.

However, what Joy Boy didn't expect was...

His plan failed!

Because not long after the Ark named Noah was completed, a war against the Great Kingdom suddenly broke out!

But the opponent in this war was someone Joy Boy had never expected—his former ally, the Twenty Royal Families!

It turns out that recently, twenty observant members of the royal family have already discovered...

The curse of the Lunaria God-King before his death was not just empty words.

They were astonished to observe that the world's oceans did not stop swallowing the land just because the tsunamis had ceased, but continued to erode human living space at a rate that was gradually increasing every year.

This made the twenty royal families realize that staying in their kingdoms was a form of slow suicide!

To truly escape this crisis, they must also set foot on the Red Line!

Although the Red Earth is the largest landmass in the world after the catastrophe, it is entirely covered with hard rock, making it unsuitable for production.

Therefore, if they rashly move to the Red Earth, all that awaits them is to become vassals of a huge kingdom or to fend for themselves.

This was utterly incomprehensible to some of the twenty royal families who had also participated in overthrowing the rule of the Lunaria and bringing new life to the world.

During this period, the twenty royal families also held several secret meetings behind the backs of the vast kingdom.

Ultimately, they decided to take up their weapons again, conquer the vast kingdom, and reclaim the throne that was rightfully theirs.

The poor twenty kings are still unaware...

All their current thoughts are simply the seeds that Im planted for them over the years.

But Im's goal has always been the same!

Seize the Sun Crystal from Joy Boy, fulfill the ancestor's dying wish, and rule this world!

Of course, Joy Boy's actions in making the Great Kingdom better were also one of the straws that broke the camel's back for the Twenty Royal Families.

This was a decision they had to make in order to prevent their descendants or kingdom from becoming vassals of a certain power in the future.

Instigated by Im, the twenty royal families quickly began to assemble their armies and launch an attack on the Great Kingdom!

When Joey Boy learned of this news, he was completely dumbfounded!

He couldn't understand why his former teammates and comrades would suddenly turn against him.

The giants' long lifespans made their concept of time different from that of ordinary humans.

For the Twenty Royal Families, it may have been a long time, but for Joy Boy, it was just a small part of his life.

The naive boy didn't understand any of this.

At the same time, because all of this happened so suddenly, even with the three great weapons of a giant warship, the friendship of the mermaid princess, and the flying machine of the Kingdom of God, Joy Boy was still caught off guard by the twenty royal families.
