Teaching Nami

"Really?" Luffy suddenly remembered that there was such a thing.

Haku turned her gaze to the depths of the Sea, where she saw two red, lantern-like objects approaching at an extremely fast speed.

Luffy, Zoro, and Sanji, who had noticed this, all looked in that direction!

A Sea King was drawn to the ship's lights, clearly intending to attack the Thousand Sunny!

"Th—what is that?" Usopp asked nervously.

When the full form of this sea king was revealed to everyone, Usopp, Nami, and Chopper were so shocked they were speechless.

Luffy's eyes lit up, indicating that he wanted to eat the meat cooked by this Sea King. He stretched out his hand, wanting to punch through the ship's membrane!

Zoro placed his hand on the hilt of his sword, intending to wait until the Sea King got closer before making his move.

Sanji was already planning which part of the Sea King's body he would cut off a piece of meat to cook into what kind of delicious meal!

Haku raised an eyebrow and said, "If you don't stop these two soon, we might have to swim to Sabaody Archipelago ourselves."

"Idiot! Do you want everyone to die with you?!" Nami, realizing what was happening, delivered a swift chop to Luffy's head, leaving a large bump, while Zoro was forcibly held back by Usopp, preventing him from drawing his sword!

Sensing the Sea King getting closer, Robin, sitting opposite Haku, said with a smile, "Since our captain can't take action, then this Sea King is yours!"

Haku did not object, but a glint of red flashed in his eyes.

Immediately, Haku glared at the rapidly approaching Sea King!

The overwhelming power possessed by Conqueror's Haki was completely overwhelmed by that Sea King.

The latter's body suddenly stiffened, frozen in place, unable to move.

"Roll!"

Haku spoke softly, her voice conveying a meaning that seemed to travel through the sea to the other person.

Without hesitation, the Sea King flew away as if fleeing from some monstrous flood.

Luffy, Zoro, Sanji, and the others were all surprised to see this. They hadn't expected that Haku could make the giant Sea King turn and flee with just a single command.

Luffy, rubbing the bag Nami had knocked out of him, grinned foolishly and said, "Haha, Haku, you're really amazing!"

Zoro, his face serious, looked at Haku, a glint of fighting spirit in his eyes. "Your power is indeed as he said! Extremely strong!"

Haku paused, then, as if remembering something, said, "That Hawk Eyes guy?"

Zoro nodded!

Haku thought for a moment and said, "You know what, I didn't expect Dracule Mihawk to have such a high opinion of me. I almost forgot that a fight between me and that guy was bound to happen sooner or later!"

Hawk Eyes Mihawk, hailed as the "World's Greatest Swordsman"!

With the arrival of Haku, the Great Swordsman's status has been somewhat shaken.

Many people are speculating about the level of swordsmanship that Haku, who also wields a Zanpakuto that is no less Twelve Supreme Grade Blades Zanpakuto of the Twelve Grades, has reached, and whether he can truly surpass Hawk Eyes and become the new World's Greatest Swordsman.

Hearing these rumors, Haku simply smiled. He knew that his battle with Hawk Eyes wasn't a simple contest of victory or defeat, but rather an exchange and growth in swordsmanship. He looked forward to meeting Hawk Eyes again, hoping to learn more from him.

The atmosphere on the ship gradually relaxed. Usopp and Chopper were still marveling at Haku's strength, while Franky began to busy himself checking the damage to the ship, preparing for the next leg of the voyage.

As for Haku, he certainly wasn't idle.

Although Nami had only recently consumed the Rumble-Rumble Fruit and its power was not yet fully developed, Haku knew she needed time to adapt to and train this new power. Therefore, he approached Nami and offered to help her train with the Rumble-Rumble Fruit.

"First of all, the Rumble-Rumble Fruit is an extremely rare and powerful Logia Devil Fruit, containing immense power. But as you know, great power comes with risks. You must learn how to control it in order to transform it into a force to protect yourself and your companions," Haku said seriously to Nami.

Nami listened intently as Haku explained how to use the Rumble-Rumble Fruit!

Haku continued explaining to Nami, "After you ate the Rumble-Rumble Fruit, your body will become like lightning, making you immune to physical attacks, most energy attacks, and non- Haki attacks. Simply put, you'll become Elementalization!"

"Like Luffy's Ace?" Nami said, remembering something.

Haku understood that the other person had seen Ace Elementalization.

He nodded and said, "That's right! Elementalization refers to Logia Devil Fruit User transforming their bodies into specific natural elements, such as fire, ice, or smoke, for attack or evasion. This ability allows the user's body to subconsciously and automatically Elementalization when attacked or ambushed, without the user's conscious control, enabling them to evade attacks without having to dodge."

"Like this!" Haku suddenly pulled out a Golden Holy Spear and plunged it into Nami's body!

"You bastard! You want to kill me?!" Nami unconsciously used her Haki again, pinning Haku down and whipping her repeatedly!

"Oh my god! You guys need to come help me!" Haku cried out for help.

Luffy and the others, who were watching the explanation from the side, were startled by Haku's actions and then ignored Haku's pleas for help, each pretending not to see Nami beating up Haku.

"You guys are ruthless!" Haku said, her face bruised and swollen.

Nami was able to back down so easily because Haku had just given the Golden Holy Spear to her! (Actually, Nami had Haku into giving her the Golden Holy Spear after discovering it was 99% golden!)

Haku's actions can be seen as "spending money to avoid further trouble."

He smiled helplessly and continued, "Alright, let's get back to the main topic. People who use the Rumble-Rumble Fruit can freely release blue High-Voltage Electricity to attack, enhance the range of their Observation Haki with Electric Waves, Teleportation using the fruit, possess terrifying destructive power, and also have the speed and power of lightning, create Thunder Beast, and have Electrotherapy abilities."

"Ah! I'm so envious of that ability!" Usopp said wistfully, looking at Haku's position.

Keep in mind that he was there when Haku gave the Rumble-Rumble Fruit to Nami!

Haku ignored the other person's gaze!

He continued, "Defensively, even if fatally wounded, the Rumble-Rumble Fruit powers can use their electrical pulses to press on the heart and revive it. However, the Rumble-Rumble Fruit has a significant weakness: it is ineffective against insulators."
