One piece, rewarded thunder fruit at the beginning

Rayleigh stood there holding his sword, not launching an attack, but a terrifying aura burst out from him, overwhelming Amber.

Rayleigh seemed like the only king between heaven and earth. The air cracked due to the Conqueror's Haki's vibrations. The ground and trees also split from the Haki's pressure, and dust flew everywhere.

Amber felt as if he was facing the entire world. The overwhelming aura pressed down on him, forcing him to submit.

This was completely different from the Conqueror's Haki Rayleigh had released in the bar earlier.

"So... that's it! This is Conqueror's Haki!" Amber murmured, then his eyes widened. His aura suddenly changed, and a similar Conqueror's Haki rose up from within him.

The two auras clashed fiercely. This was Amber's Conqueror's Haki. Although it had never awakened before, it finally did under Rayleigh's pressure.

"You... too?" Rayleigh looked a bit shocked.

Conqueror's Haki can only be awakened by one in a million. It signifies the potential to become a king. Everyone who possesses it is destined to be extraordinary.

Rayleigh wanted to continue testing the boy in front of him and increased the pressure.

Amber had just awakened his Haki and wasn't very skilled yet. He was quickly overwhelmed by Rayleigh's Conqueror's Haki. Despite being at a disadvantage, he managed to protect himself.

The clash of their Conqueror's Haki changed the sky and earth's colors. Red and black lightning crackled around them, airwaves rolled, the ground shattered, and the clouds were blown away.

Even the crew on the Thor in the distance could feel the powerful pressure.

"What... what kind of power is this!" Zoro broke into a cold sweat as he looked toward the center of the clash.

"This... is so scary! I feel like I'm about to faint!" Conis, the weakest among them, who had just eaten a Devil Fruit, said weakly while being supported by Nami.

"Amber... will he be okay?" Nami said worriedly, looking in the direction of the battle.

"This... this is Conqueror's Haki! Little Amber... he's really something special!" Shakky looked as shocked as Rayleigh. She and Rayleigh had stayed in the Sabaody Archipelago for over 20 years and had seen many pirates, but few with Conqueror's Haki.

...

"It's amazing! You actually awakened Conqueror's Haki during the battle... What kind of path will your future take?" Rayleigh was full of expectations for Amber's future.

"Who knows!" Amber smiled lightly.

"Is that so!? Then, here I come, be careful!"

Rayleigh shouted and placed his sword across his chest, his momentum suddenly changing. If he was the king who ruled the sea before, now he was the Shinigami, taking away life.

The sword's aurora gradually turned black, a sign of Conqueror's Haki.

Rayleigh waved his sword lightly without naming the move.

A massive slash spanned the sky and earth, heading straight for Amber.

Amber sensed a huge danger approaching.

"Crack!"

Starting from Rayleigh's sword, everything in front began to split. The ground, trees, air, and clouds in the sky were all cleaved in half.

The slash moved rapidly toward Amber.

"Holy crap, this old man is serious. If I get hit by this, I'll really... die!!!" Amber was shocked.

Should he teleport away?

Amber questioned himself.

No! I can stop it!

Amber instantly strengthened his resolve. Life would be boring without challenges.

His eyes turned blood red, with strange patterns inside the pupils, and Mangekyō Sharingan appeared.

The Mangekyō Sharingan spun rapidly, and blood trickled from Amber's eyes.

Rows of skeletons began to form. They rapidly evolved into the fourth form of Crow Tengu, with the defensive artifact Yata Mirror blocking in front of him.

"Bang!"

The slash struck the Yata Mirror hard.

The Yata Mirror, a true defensive artifact, blocked Rayleigh's slash, but cracks soon appeared, threatening to break through to Amber inside Susanoo.

"Damn it! Since the fourth form can't stop it, let's go full body!!!"

Susanoo in the form of Crow Tengu immediately expanded, growing larger, forming complete hands and feet, becoming a full human form.

A pair of wings grew from its back, holding a huge Totsuka Sword in its right hand, and the Yata Mirror in its left.

It grew over 200 meters tall, like a giant holding up the world.

With a flick of the Yata Mirror in Susanoo's hand, Rayleigh's slash was deflected, flying off into the sea, splitting it in half.

From the sky, the entire uninhabited island was cleaved in two, but the crack stopped in front of Susanoo.

"What... what is this move?" Looking at the 200-meter red giant in front of him, Rayleigh felt tiny, despite his vast experience.

"Susanoo! Those who have seen this call it the power of God!" Amber replied lightly.

...

On the Thor in the distance.

"What... what is this!!! Is this also Little Amber's move?" Shakky was the most surprised.

"It's so powerful! It's so big! This is the move Amber used against the Admiral last time!" Chopper exclaimed.

"I remember Amber didn't look like this when he used it last time. Is this its true form? Did he hold back against the Admiral?" Robin analyzed rationally.

"Amber!" Nami murmured softly, looking at the huge giant.

"This giant is really super cool!"

...

"Uncle Rayleigh, since I took a move from you, now it's your turn to take a move from me." The Yata Mirror in Susanoo's hand disappeared, replaced by the Totsuka Sword held with both hands.

"Wait... wait, Amber!!!" Rayleigh interrupted hurriedly.

"Prehistoric: Heaven and Earth Split!!!" Amber ignored him and controlled Susanoo to launch the attack.

The Totsuka Sword swung down fiercely, a red slash cleaving the world in two. Rayleigh used his exceptional Observation Haki to dodge narrowly.

The slash didn't disappear after splitting the island; it continued, splitting the ocean it passed in two. Its destructive power was even greater than Rayleigh's move, and this was just Amber's basic attack!
