One Piece: Starting with just a sword, the crew relies entirely on slashing.

After listening to Oda's account and pondering it for a while, Wang Zhe decided that no matter what secrets Black Moon might hold, he had to find a way to win her over. With that in mind, he asked...

"Oda-sensei, since the East Blue isn't suitable for a young Sea King like Black Moon to grow up, why not take him to the Grand Line?"

Oda's lips twitched. "I've already said I'm under house arrest. I have to be careful even when I appear in the East Blue, let alone go to the Grand Line. Besides, I don't feel comfortable letting it go to the Grand Line alone."

"Sea Kings have long lifespans, and Black Moon is still in its infancy. After growing to a certain extent here, it will naturally return to the Grand Line."

Seeing an opportunity in Oda's words, Wang Zhe quickly spoke up, "Let me take Black Moon with me. I will make sure to deliver it safely."

Upon hearing this, Oda frowned, then sighed. "Sigh, if it's willing, you can take it with you, but once you reach the Grand Line, you must let it return to the sea. It will quickly pass through its infancy there and shouldn't easily appear in front of others."

Wang Zhe patted his chest and said, "Don't worry, Mr. Oda, I promise you."

Sensing something amiss in his words, Kurosaki Ryoto interjected, "Wang Zhe, why don't you join the Navy or the Army? Do you also want to find One Piece? If you like the sea, with your strength and by using some of our connections, joining the Navy will definitely be a smooth ride for you."

Wang Zhe did not answer Kurosaki Ryoto's question, but Kato Kazuki, who was standing next to him, quickly spoke up when he saw that something was wrong.

"Ryou, everyone has their own chosen path. Besides, is the World Government really right?"

Kurosaki Ryoto fell silent and stopped speaking. Oda smiled and said, "Whether it's the Navy or pirates, as long as they can bring hope to the world, whatever path they choose is the right one."

Wang Zhe also smiled and echoed, "Don't worry, you three, I will never forget my original intention for going to sea."

After chatting and laughing for a while, Black Moon pulled the Supreme Ship and continued sailing out to sea. Wang Zhe sat on Black Moon's head, constantly tempting and persuading it to join them on their journey to the Grand Line.

Black Moon moved very quickly, and after an unknown amount of time, he led everyone to a small burnt stone with the number zero engraved on its surface.

Looking at the small reef that could only hold a few people, Wang Zhe was dumbfounded. "This is the secret base?"

Oda burst into laughter, "Hahaha, that's right, this is it! How about it? Isn't it incredibly well-hidden?"

Wang Zhe was speechless. It was indeed quite secretive; a single wave could easily cover it up. However, he was clearly not that foolish; there must be some secret involved.

Kurosaki Ryoto is usually a straightforward person. "Our secret base is under the sea, with trees. I'll leave the coating of the ships to you."

Kazuki Kato smiled and took a metal box out of his pocket, placing it on the deck of the Supreme. "It's been a long time since we used this. Now that we don't need it anymore, we'll leave the coated box on this ship for you."

As the metal box, known as the coating box, slowly opened, a transparent bubble appeared, gradually growing larger and larger until it passed through everyone's bodies and enveloped the entire ship.

Black Moon swam its massive body, constantly rotating around the reef, gradually forming a huge whirlpool, and slowly carried the Supreme into the sea.

As the surface of the sea returned to calm, Black Moon pulled the Supreme Ship deeper and deeper into the ocean. On board, Wang Zhe observed the scenery outside through the huge bubbles. This was the first time he had observed the sea so closely, and he was quite excited.

As time passed and the light grew dimmer, suddenly a ray of light appeared ahead. The black moon rushed straight through the ocean currents surrounding the light, leading the group into it.

The East Blue is not as unfathomably deep as the Grand Line. Through Oda's explanation, Wang Zhe also learned that this place is similar to Fishman Island, only not as huge, but it can still be considered a small island.

After delivering everyone, Black Moon wagged its tail at Wang Zhe and his group before breaking through the ocean currents again and returning to the sea.

There were no magnificent buildings or beautiful scenery here; only a few small houses could be vaguely seen. Wang Zhe noticed an old man with a hunched back squatting in front of a row of tombstones not far away.

Meeting Wang Zhe's gaze, Oda led the group toward the hunched figure and said calmly, "Nagri, I've brought back a very interesting young man. How does he compare to that little boy you mentioned?"

Nagri slowly turned his head, his aged eyes devoid of any emotion, his voice hoarse, "I have fulfilled my dream. My time is running out. I suppose that child from back then has already set sail. Young people these days are truly terrifying."

As if remembering something, Wang Zhe exclaimed, "It's you! The hammer king Naguri, who met Luffy at the garbage dump and taught him for a while! You're still alive!"

Nagri's aged eyes finally changed. "You've heard my story?"

"Uh, I've heard Luffy mention it. Looks like you've found your old crewmates." Wang Zhe scratched his head, gave an awkward smile, and spun a lie. He couldn't very well say that he saw it in an anime, could he?

"Hahaha, so you're Luffy's friend. If you have time, please tell Luffy that my dream has come true, and that he must also stick to his own dream."

"Don't worry, Nagley, I'll tell him."

After chatting for a while, A, B, C, and D were assigned to repair the dilapidated Supreme, and Oda led everyone to a house.

"Wang Zhe, although you are very strong, it is far from enough for your ambitions."

"Although we don't know why your attacks are so powerful, your stamina simply can't keep up with the consumption, and your use of Haki is also terrible. If you're willing, stay here for a while, and we'll do our best to teach you how to use the three types of Haki."

Wang Zhe naturally nodded in agreement with delight. Although there was not much time left in the limited-time event, learning how to use domineering aura was obviously much more important than this.

After some arrangements, Sikong Zhen and Meng Tian were respectively taught Armament Haki and Observation Haki by Kurosaki Ryoto and Kato Kazuki.

Of course, Nagri wasn't idle either. He was responsible for teaching A, B, C, and D, and assisting in the repair of the Supreme, after all, he was someone who could build ships all by himself.

After everyone had left, Wang Zhe looked at Oda with sharp eyes and said, "Old man, since you and Roger were good friends, you must be proficient in some swordsmanship as well."

"Hahaha, you little rascal, I'm mainly responsible for teaching you how to use the three types of Haki. My swordsmanship isn't very good. I can only barely teach you a not-so-perfect Divine Evasion."

Wang Zhe wasn't disappointed. After all, mastering the three types of Haki was something he desperately needed. Besides, would Oda's swordsmanship really be weak? It was just a step weaker compared to the great swordsmen. One move, Divine Evasion, was enough.

Oda paused for a moment, then continued, "Speaking of swordsmanship, I've connected you with an excellent teacher. He should be arriving soon. Come on, I'll take you to meet him."

Upon hearing this, Wang Zhe couldn't help but speculate about the identity of the swordsmanship teacher Oda mentioned. "Could a swordsmanship expert appearing in the East Blue at this time be Hawkeye? Or that mysterious man?"

With questions in mind, Oda and Wang Zhe arrived near the area surrounding the ocean current and waited quietly.

Of course, they weren't idle while waiting. Oda kept explaining the principles and applications of the three types of Haki to Wang Zhe, and occasionally demonstrated them. Oda was quite surprised by Wang Zhe's comprehension.

After a while, Wang Zhe suddenly had a faint feeling. His Observation Haki began to emerge. He slowly looked at a current of the sea and sensed an extremely powerful being there.

Wang Zhe's gaze pierced through the surrounding ocean currents, and he saw a sudden slash coming from there. Seeing Oda's calm demeanor, Wang Zhe made no move.

"Whoosh!"

An invisible sword aura parted the ocean currents, and the water mist generated by the impact covered the area, preventing any seawater from entering, as if something was subtly isolating everything.

A tall, slender figure with a sword at his waist slowly emerged from the mist. As he entered, the sea currents gradually calmed down, and apart from the pervasive mist, it seemed that nothing had happened.

Looking at the silhouette, Wang Zhe decisively ruled out the assumption that the person was Hawkeye. Could it be him?
