One Piece: Start with Zanpakutō

"The source of the Haki Core."

"Your comprehension is extraordinary. With Zephyr's explanation, you can use the Ultimate Haki Power as the foundation to Condense the three Forms of Haki in the upper, middle, and lower Cores, transforming them into the Armament Form of Haki Seed, the Observation Form of Haki Seed, and the Conqueror Form of Haki Seed."

"There is no need to fight. The three-Forms Haki Seed will practice Haki energy all the time and increase the strength of the three-Forms Haki energy on its own."

After digesting the information that emerged in his mind, Rosen's eyes flashed with a gleam of light.

His extraordinary comprehension was far beyond what he had imagined and he was even more motivated.

Originally, he was thinking of deducing a method to increase the strength of his Haki aura through practice or combat, but he never expected that he would deduce the origin of the Haki Core.

It not only works on Observation Haki and Armament Haki, but it is also applicable to Conqueror Haki which can only be controlled but not Practiced.

Once the three Forms of Haki aura are transformed into a Haki Seed, not only can the strength of the Haki aura be increased through combat, but it can also be increased through self-Practice.

From this moment on, even if Rosen does not follow Luffy's route of improvement through fighting, but just stays in the Marine Headquarters every day, the Three-Forms Haki Seed can help him practice the three-Forms Haki to the extreme.

He had no idea how strong this extreme was.

You can only guess.

Probably the worst, his Armament Haki is comparable to Garp; his Observation Haki is comparable to Katakuri; and his Conqueror Haki is comparable to Roger and Red Hair.

As for whether the source of Haki Core has other functions, you will only know it after practicing it.

After all,

This Haki practice method was just derived by Rosen, and even he himself had never practiced it before.

"Come with me."

Seeing that Rosen seemed to have stopped thinking, Zephyr pulled Rosen aside.

"Go ahead."

"Did you just comprehend some Haki skills?"

Perhaps it was because Rosen's comprehension was too extraordinary and he had too many previous convictions, so when Zephyr talked about comprehending Haki power, he directly used the word "again".

"It's not much of a skill."

"I just happened to realize a way to increase the strength of my Haki aura through practice."

"It's just like the Blut Vene (Calm Blood Dress). It's only suitable for me. If others try to practice it, they will only kill themselves."

Facing Zephyr.

Rosen did not hide too much and revealed a little about the function of the source of Core.

The fact that Sengoku came in person yesterday to teach him how to use Conqueror's Haki was enough to prove that as long as he was good enough, there would be no such thing as a tree that stands out in the forest being destroyed by the wind in the Navy Headquarters.

Of course, the prerequisite is that he must stand firmly on the side of Justice.

"I knew it was like this."

Zephyr's expression was a little numb.

He had just said that Haki skills are acquired through practice, and Haki strength is acquired through fighting, but within a short while, Rosen broke this statement.

Not only skills, but even Haki strength can be trained.

"Don't tell this to anyone other than me."

"Not even Sengoku and Garp."

"They can be trusted, but people outside the Navy Headquarters cannot be trusted."

Zephyr forced himself to suppress his inner shock and pointed upwards.

Rosen understood immediately.

Mary Geoise stands on top of the red earth continent.

That is the world government.

According to Zephyr, you can show off as much as you want in the Marine Headquarters, but you must never show off to the point of making the World Government uneasy.

"Since you have figured out this method, continue to practice it, but don't fall behind in the battle."

"Like you said, fighting alone or training alone is not efficient enough to increase the strength of Haki."

"A two-pronged approach is the best for you."

Seeing that Rosen understood what he meant, Zephyr did not forget to remind him.

Don't just rely on Practice once you have the source of Core without fighting.

After all,

In addition to increasing the strength of Haki, fighting can also hone Haki skills, increase experience, awareness, and physical fitness.

"I want both fighting and training."

Rosen nodded.

Didn't he deduce the origin of Core because he felt that relying solely on combat to increase the strength of his Haki aura was too inefficient?

Now that he has realized the source of Core, he will certainly not give up fighting to increase the strength of his Haki power.

"I'm relieved if you think so."

Zephyr smiled with relief, then took Rosen back to their original position and continued the class:

"Back to the topic just now."

"Only through actual combat can the strength of Haki power be taken to a higher level."

"So, today's lesson is simple. It's the two of you fighting Rosen."

He said to the three people in front of him.

"Teacher Zephyr."

"Although it was wrong for Rosen to be distracted in class just now, you don't have to punish him like this."

"Gion and I teamed up to beat him up. Let's not talk about whether it's fair or not. Just to say that this is not a real fight, but a beating."

Tokikake gave Rosen a look that seemed to say, I am a good friend.

"Teacher Zephyr."

"To improve in actual combat, one must also be evenly matched!"

"Will two against one really help us?"

Gion also said.

She came to the Naval Academy to improve herself, not to suppress others.

It is true that Rosen is better than herself, but that doesn't mean she will be jealous of him.

"Do you think too highly of Rosen, or do you think too highly of yourself?"

"It is the greatest fairness to you if I let you two fight against one."

"Only two against one can prevent you from being beaten unilaterally by Rosen, which will not provide any practical training."

Zephyr Sneered.

"How is that possible?"

"Teacher Zephyr, I admit that Rosen is a little ahead of me and Gion in the progress of practicing Haki, and he even mastered the intermediate Conqueror's Haki, but that kind of thing can only be used to clean up the small fish."

"For masters like me and Gion, it has no real effect at all."

Tokikake felt that he was being looked down upon and expressed strong dissatisfaction.

"An expert?"

"Okay, I will accept your statement for now."

"But who told you that Rosen is only a little ahead of you in the progress of practicing Haki?"

Hearing this, Zephyr couldn't help but laugh at Tokikake's anger.

To be honest, it is true that he favors Rosen personally, but he is absolutely not partial in education.

Two against one, it's really for Tokikake and Gion's sake.

Only in this way can all three students grow in this class.

"As for Armament Haki, everyone can only Harden. What else can it be but a little bit?"

"That's right."

"This little bit is because Rosen's Haki Forms are taken into account."

The addition is well-founded.

"Combined with Zhan Guo and I, I gave Rosen two lessons yesterday."

"In the first class, he mastered the Armament Haki's Hardening, Imbuement, Emission and Internal Destruction, and also created a fifth Armament Haki technique."

"During the break, he awakened his Conqueror's Haki on his own and entered the intermediate Conqueror's Haki level."

"As for the second class, he mastered the Infusion of Conqueror's Haki, and Observation Haki."

Zephyr raised two fingers, and at the same time, he did not forget to appreciate Tokikake's wonderful expression changes:

"One word."

"In two lessons, Rosen learned all the three-Forms of Haki skills."

"Tell me, old man, is there a little difference between you two?"

As soon as these words came out.

Both Tokikake and Gion were stunned.

Just two classes.

How did Rosen manage to learn the three Forms of Haki, plus a bunch of Haki techniques, in such a short time?

No.

Not only did he learn all of them, but he also created his own new Armament haki techniques.

"It turns out that I didn't catch up with him, but could only barely see his back."

Gion thought of her encounter with Rosen in the dormitory corridor last night, and for the first time she felt a sense of bitterness and powerlessness in her heart.

She was so complacent before, thinking she had caught up with the man in front of her.

Never thought.

Even the taillights of the car are almost invisible.
