Opening: Devil Fruit can be upgraded

"For the sake of the overall situation, I will definitely not kill them both."Roger pouted and said

"Hey, why don't you save Big Mom's son who you killed before?" Zefa rolled his eyes and said

"Then... you should come with me."

Rogge was helpless, but Zephyr was still strong. After installing the Seastone Arm, Zephyr had to be careful even against the generals.

When Rogge was training his Armament Haki, he fought with Zephyr a lot.

In order to hide his Observation Haki, Rogge was caught by Zephyr several times. Once Rogge was caught, the battle was over.

Because he had to pretend to be very weak and give up resistance, otherwise he, as a fruit ability user, would not be afraid of the Seastone ability being discovered. He would definitely be caught and used as a guinea pig.

"Humph, that's right. Besides, I have long wanted to fight these scums who call themselves the Four Emperors. A mere pirate is worthy of being called an emperor? What a joke!"

Zeff said as he became increasingly angry. His malice towards pirates also manifested itself as momentum, which surprised Rogge.

: You really don't see the look of not killing the admiral back then. Pirates, why are you so cruel to Admiral Zeffer? Isn't Sakaski better?

Without further thought, Rogge and Zeffer soon arrived at an uninhabited island - Edsalia.

Putting the warship aside, Zeffer sensed the movements of the entire island through his observation Haki, and then said,"They haven't come yet, let's wait."

"A fight? Oh, interesting."Rogge sneered, and then fought with Zefa, looking towards the sea and waiting.

As the agreed time approached, a sailboat gradually approached.

"It's not Big Mom's Queen's Chant. It seems that the other party still keeps his promise."Zefa said confidently with his arms folded across his chest.

"Wait, the teacher seems to have another ship!" Ain has sharp eyes and can quickly spot the extra ship at the farthest point on the horizon.

"There is another ship? Can you tell whose it is?"Zeffa asked nervously.

If it was Big Mom's, he would have to retreat with his men immediately, and he might even have to stay behind to cover their retreat!

"There is an elephant on the bow, and Kaido's flag! It's Jack, one of the Three Calamities!" Ain made a quick judgment and said

"Jack? Phew, not bad. Zephyr said with a sigh of relief. It seems that having more Four Emperors is just like that.

"……"

Rogge rolled his eyes at Zefa, but Ain and the others looked at Zefa with admiration.

It was indeed difficult for people with different beliefs to become friends. Rogge thought to himself.

"But I didn't expect Kaido's pirate group to join in the fun, what a surprise."

Zefa joked while waving his arms to stretch his shins, and his confident look was quite like the general he once was.

"Well, it should be because I killed that wolf cub worth 300 million berries, so Kaido came to settle the score with us after knowing what happened between us and Big Mom."Rogge said lightly, and began to wipe his knife.

"A wolf cub worth 300 million berries? Hahahaha, very good, today we will kill another elephant cub worth 1 billion berries to let Kaido know how powerful we are."Zeffa said complacently.

"Teacher, have you forgotten our mission? Defeat them, not kill them.

Although Ain hated pirates, their pirate guerrillas still belonged to the navy organization. If Sengoku ordered him to do so, he still had to tell Zefa.

"Got it, got it. That old man always says meaningless things. Will I ignore his overall situation?"Zefa said unhappily.

After hearing this, Ain did not roll his eyes like Rogge, but just looked at Rogge deeply, the meaning was self-evident: Teacher, I believe you, remember it clearly, don't kill him!

"……"Roger was caught in the crossfire and helplessly spread his hands to Xiu Zuo. He was the only acquaintance on the ship besides the teacher.

Xiu Zuo gave Roger a look of"Don't worry, I believe you", which gave Roger a great"comfort".

The two pirate ships entered the island one after another

"Humph, Jack, what are you doing here? Picking up corpses?"Cracker, as the leader of this operation, spoke first.

But Jack just glanced at Cracker coldly and said nothing.

He didn't take a general star with a lower bounty than himself seriously. However, in fact, except Kaido and his two elder brothers, Jack didn't take anyone seriously at all. After all, he was the man who dared to rob the admiral's ship.

""Who is Roger?" Jack walked forward with a ruthless pace and shouted in a rough tone.

Roger was about to answer, but Zefa took a step forward and waved his seastone arm, signaling Jack to attack.

"Your name is Roger?!"

Jack stepped forward immediately without receiving any provocation. His goal was very clear, which was to kill Roger. As for the others, he would also kill them, but only under the premise of confirming the mission.

"No, but if you want to attack Roger, you have to go past me."Zeffa sneered.

Jack narrowed his eyes, obviously he was angry.

He pulled out the Shortel knife with his backhand, and then walked towards Zefa with heavy steps like an elephant.

""Hahaha, the pirates are damned, smash blaster!"

Zephyr roared, aimed his seastone arm at Jack, and fired a blast.

Jack was caught off guard by the sudden bombardment and was hit directly.

Bang!

Looking at Jack who was hit head-on, Zephyr sneered, as if he was laughing at the other party's arrogance.

But when the smoke and dust dissipated, Zephyr soon stopped laughing, and Jack was unharmed!

"An awakened animal-type ability user?" Zefa looked at Jack seriously and said

""Very good, you made me angry! Navy."

Jack said angrily, and then transformed into a mammoth and appeared in front of everyone.

""Go to hell, Marine!"

Jack, who had grown bigger, stomped down hard, trying to crush Zephyr to death.

But Zephyr was not panicked at all. As a man who had reached the peak of physical skills, he directly hit back with his seastone arm.

Bang!

The two men punched each other, making a terrible noise that made some weak pirates and marines cover their ears.

"Humph, two monsters. Snag said with a trace of cold sweat on his forehead.

His brother Cracker, who came with him, sneered at Snag, not knowing whether he was laughing at his courage or disdain for Zefa and the others.

"That's it, pirate!"

Zefa roared, then grabbed Jack's elephant foot with the seastone.

""Huh? What!" Jack suddenly felt that his strength was seriously lost,"Why did I suddenly lose my strength?!"
