Looking at Karp, who was clenching his fists and making a sound of his knuckles, Ace and Sabo were very unconvinced, but they still admitted it very decisively.

God knows how this old man exercised his fists, and it really hurts to hit someone.

Luffy in the tree saw that something was wrong, and he immediately slid down the trunk, but instead of running away, he rushed to Karp and hammered him with a small fist against Karp's leg.

Looking at Luffy, who had a rather serious expression, Dusty and Guina glanced at William a little speechlessly, and the meaning in their eyes was very clear.

What an amiable family!

"Luffy, Ace, Sabo, the old man is here to introduce you. He's William, and then they're Guina, Dusty, and Bartolomeo, and for the rest of the day, the old man will let you train with them, and if you can't keep up with the training, the old man will let you taste the iron fist of love! ”

Karp showed a smile, a sheep is a herding, a group of sheep is also a herding, since you want to train William, then even take Ace Luffy and them to train together.

With an example, this group of arrogant boys will definitely train very hard.

He's such a wise and brave grandfather!

"Training with them? Is he strong? ”

Ace glanced at William provocatively, Dusty and Guina had just shown their strength, he thought that he couldn't take a sword from these two girls, but he hadn't seen William's skills yet, so he didn't have any friendliness towards this boy who was a few years older than him.

"Hello, I'm Sabo, nice to meet you."

Sabo, who came from an aristocratic background, had good manners, and he gave a gentlemanly salute to Guina and Dusty very seriously.

"Haha, William, you can show a hand to these three imps who don't know the height of the sky, otherwise you may not have any peaceful days in the future."

Karp laughed again, and William didn't know where Karp's laughter was being hit by the current situation, so he only felt a little speechless.

However, since Karp asked him to show his hand, it was natural to convince Ace and Luffy.

William has no opinion on the son of One Piece, but for Ace, who wants to be a pirate, William will definitely not have a good face for him.

At present, among the abilities that William has mastered, there are not many tricks that can burst out with great momentum, but there happens to be one that is very suitable for Ace to show.

Airplanes!

William stretched out his hand, and a ball of crimson flame rose in his palm, then condensed into a huge fireball.

As the pitch-black ghost aura enveloped William's body, the size of the fireball suddenly doubled!

"It's scary!"

The innocent Luffy made no secret of his fear, he hid behind Sabo and cautiously poked his head out to look at the huge fireball.

A cold sweat also appeared on Sabo and Ace's foreheads, and they stared at the huge fireball floating above William's palm, and from that fireball, they felt a violent energy.

This pressure is much greater than when they face the beasts in the mountains!

"Aggression is like fire!"

After condensing his strength for about half a minute, William smiled slightly, and threw the fireball in his hand into the jungle in the distance, and then heard a loud explosion, and the terrifying shockwave suddenly tore the surrounding forest to pieces.

When Karp helped the three little ones block the shockwave, Ace and Sabo's eyes were full of solemnity.

I saw that the jungle, which was originally a beautiful environment, has now appeared a bare area about 100 meters in diameter, and at the edge of this area, the crimson flames are slowly extinguishing.

"Will die!"

Ace and Sabo glanced at each other, and the first reaction in their hearts was that if they took this trick, they would definitely die!

"Grandpa, why does this brother summon fireballs?"

Little Luffy tugged at Karp's trouser leg a little ignorantly, his eyes were full of curiosity, and at the same time, he could see a hint of excitement.

"Haha, because William is a Devil Fruit powerhouse."

Karp scratched his head, speaking of which, he could cause damage far beyond this level with a casual blow, but it had to be said that the Devil Fruit Ability was indeed stronger than the Pure Body Technique in some threats.

"Grandpa, grandpa, I'm going to be a Devil Fruit powerhouse too!"

Luffy, who didn't know what the Devil Fruit was, was in a hurry, he dragged Karp's trouser leg and kept being coquettish, and the relationship between little Luffy and Karp at this age was still quite good.

Ace and Sabo, who had a certain understanding of the common sense of the sea, were a little surprised, because they didn't expect that the secret treasure of the sea that only existed in the legend really existed, and they could actually see the power of this Devil Fruit with their own eyes.

It seems that the old man's statement that they may not be able to keep up with the training is true.

"Luffy, if you want to become a Devil Fruit ability, then join the Navy with the old man, and then the Devil Fruit is up to you."

Caphaha laughed, with his identity and status, no matter what Devil Fruit ability Luffy wanted, the Navy and the World Government would send it to him, even if it was a natural or phantom beast species.

Hearing his grandfather's words, Luffy immediately let go of Karp's trouser leg, and then walked to Ace's side very seriously.

"No, I want to be the king of the pirates!"

"Stupid Luffy, it's me who wants to be the king of the pirates."

"Don't quarrel between you two."

As soon as Luffy's words came out, Ace hammered Luffy's head on the side, and then pointed to his chest with a proud expression.

Looking at the two who had a conflict, Sabo was a little helpless, I don't know why, although Ace and Luffy have a good relationship, but as soon as the problem of One Piece is involved, the two will quarrel.

Guina and Dusty were in a state of confusion again, what did they hear?

The grandson of a naval hero who actually wants to become the king of the pirates!!
