Self-Created Haki Cultivation Method: Qi Body Origin Flow

"Of course."

"If I hadn't mastered Coating Hardening, how would I dare say that starting tomorrow, I'd continue being your classmate, Rosen?"

Gion's words radiated a stern confidence, but reason also told her that while she was improving, Rosen would surely remain standing still.

After all, the man before her had mastered Armament Haki Coating Hardening in just half an hour.

And the Conqueror's Haki that had swept across the entire Navy School was the best proof of all.

"Oh, right."

"You said just now that something like being unable to precisely control your Conqueror's Haki today wouldn't happen a second time."

"Could it be that you've already trained your Conqueror's Haki to the intermediate level?"

Gion had keenly caught an utterly terrifying amount of information from Rosen's muttering.

"Just luck."

Rosen smiled modestly.

"How could something like that possibly be luck?"

"Conqueror's Haki is the hardest of the Three Colors of Haki to control."

"Without a year or half of training, an ordinary king simply cannot wield it freely."

A complicated look flashed through Gion's beautiful eyes as she looked at Rosen.

She had left her dormitory tonight partly to admire the cherry blossoms and partly to relax her tense mind after spending the entire day training Armament Haki.

Yet she had unexpectedly run into Rosen in the corridor.

She had originally wanted to regain a little confidence from him, only to be dealt another blow.

She had thought she had caught up to Rosen and was no weaker than him, but in truth, she could only barely see the man's back.

"There are still classes tomorrow."

"I assume you do too."

"Let's leave it at that for tonight, classmate Gion."

Rosen glanced at the night sky and did not dwell further on the subject of Haki.

After bidding Gion farewell, he turned and returned to his private room.

That was one of the privileges enjoyed by students of Zefa's class.

They did not need to squeeze into a dormitory with others.

"Rosen."

Gion quietly watched Rosen's retreating figure. Only after he returned to his room and closed the dormitory door did she withdraw her gaze and look toward the cherry tree downstairs.

At that moment, her eyes flickered uncertainly. The magnificent bosom that surpassed every woman at Headquarters rose and fell slightly, while her mind was filled entirely with matters and emotions related to Rosen.

She had long since lost any interest in admiring the cherry blossoms.

Rosen got up early and arrived on time at the place where he had arranged to attend class with Zefa.

The Plaza that Sengoku had shattered yesterday while demonstrating Conqueror's Haki Coating had already been restored to its original state after a night of emergency repairs.

However, the moment he arrived at the lesson site, a capybara face nearly pressed itself against his own.

"Yo! We meet again, young man Rosen."

"What a small world!"

"Who would've thought we only parted yesterday, yet today we can keep being classmates?"

Tokikake shoved his face in front of Rosen. His smug capybara face practically had the words, "I've mastered Armament Haki Coating Hardening," written across it in bold.

"It seems you're quite happy!"

"Well then, Tokikake."

"You'd better cherish it, because your relationship as classmates can last only until the end of this lesson at most."

Before Rosen could speak, Zefa's towering, iron-tower-like figure was already standing behind Tokikake.

"Teacher Zefa."

"I don't quite understand what you mean."

Tokikake's smile froze.

"Idiot."

"Did you forget about yesterday's Conqueror's Haki?"

"Rosen has already trained his Conqueror's Haki to the intermediate level."

It was not only Tokikake who had come today. Gion, who had likewise mastered Armament Haki in a single day, was there as well.

"No big deal."

"I don't have Conqueror's Haki anyway, so that means I haven't fallen behind Rosen."

"Teacher Zefa, what are the three of us training today? Flowing Emission of Armament Haki, or Observation Haki?"

Tokikake was very good at comforting himself.

Not having Conqueror's Haki meant he had not fallen behind.

"Today's lesson is not about learning Haki techniques. It is about learning how to increase the strength of your Haki."

The moment Zefa said that, Rosen perked up his ears as well.

He had already learned every technique of the Three Colors of Haki.

What he lacked now was simply Haki strength.

Once the strength of his Haki caught up with his technical level, and he trained up his physical techniques and Swordsmanship, even without counting the Weapon Fruit, he would be a bona fide Emperor-level powerhouse.

"Remember this: Haki techniques are trained, while Haki strength is fought for."

"So, if you want to increase your Haki strength, there is only one word for it."

"Fight."

Zefa looked around at Rosen and the other two, his tone incomparably stern.

"Only through constant battle and constant use of Haki can its strength continue to grow."

"Especially once it reaches a certain level."

"Only by pushing yourself to the limit in actual combat can you rise to the next level."

Hearing Zefa's words, Rosen frowned slightly.

He was not questioning Zefa's teaching ability. On the contrary, he knew very well that Zefa was absolutely right.

Techniques were trained, and strength was fought for.

Whether it was the mediocre teacher Rayleigh or the renowned teacher Kaido, both had used this method to train Monkey D. Luffy.

However...

"Relying purely on constant fighting to increase Haki strength is high-risk and slow to show results."

"Monkey D. Luffy fought Rayleigh for two years on Rusukaina Island. After entering the New World, he fought Fish-Men, Donquixote Doflamingo, Big Mom, Katakuri... all the way to Wano Country, until he cleared Teacher Kai on Onigashima."

"Even after cheating his way through with sparks and lightning, his Haki strength still fell short of veteran Admirals and Emperors. He could only contend with them by relying on Nika Form combined with the Three Colors of Haki."

Thinking of Monkey D. Luffy's journey of cheating his way to power, which had included repeatedly risking his life, only for his Haki still to be inferior to veteran Admirals and Emperors, Rosen secretly shook his head.

"Teacher Zefa said techniques are trained and strength is fought for."

"Then can't I both fight and train?"

"One part training, one part fighting; one still, one moving. If I do both at once, the efficiency of increasing Haki strength will definitely be maxed out."

"However, the prerequisite is developing a cultivation method suitable for increasing Haki strength."

Thoughts raced through Rosen's mind, while his consciousness poured into the Three Colors of Haki.

He split his focus in two, pondering a method to improve Haki strength through cultivation while carefully comprehending the essence of the Three Colors of Haki.

Gradually.

His mind became completely immersed in the ocean of Haki, and countless flashes of inspiration burst forth.

"Young man."

"Don't space out during class."

"Teacher Zefa is famous for being strict."

Standing beside Rosen, Tokikake keenly noticed that he had drifted off and lowered his voice to remind him, but Rosen showed no reaction at all.

Seeing this, he was just about to jab Rosen with his elbow when Zefa stopped him.

"Don't call him."

Zefa stretched out one hand and, swift as lightning, locked onto Tokikake's elbow, preventing him from touching Rosen.

"He doesn't even get scolded for spacing out, and no one is allowed to disturb him either."

"Being a monster is great!"

"Even Teacher Zefa, who is famous for being strict, is this tolerant of him."

Tokikake sighed inwardly.

However.

He had no idea that Zefa's heart had already been stirred into a raging storm.

"This is exactly how it was."

"Yesterday in the Doriki testing room, he was like this, and then he comprehended Still Blood Armor, the fifth Armament Haki technique."

"Could it be that he is about to comprehend something again?"

Zefa raised a hand, signaling Gion and Tokikake to remain quiet.

Seeing his stern and serious expression, Tokikake understood that he had misunderstood Zefa.

This renowned strict teacher was not blindly indulging Rosen. Rather, something beyond his understanding was happening.

Your comprehension is heaven-defying. Using Haki Supreme Art as a foundation, you contemplated the essence of Haki and combined it with Zefa's explanation, successfully deriving a Haki cultivation method: Qi Body Origin Flow.

Qi Body Origin Flow: Using Haki Supreme Art's absolute control over Haki, plant Observation Haki, Armament Haki, and Conqueror's Haki respectively in the upper, middle, and Lower Dantian, transforming them into three Qi Infants hidden within the body. This allows the strength of the Three Colors of Haki to grow through battle, while the Qi Infants can also cultivate on their own to strengthen the Three Colors of Haki.

(Requires Haki Supreme Art. If others cultivate it, their upper, middle, and lower Dantians will rupture, resulting in death.)

After a while.

A passage of information suddenly surfaced in Rosen's mind, jolting him awake from his contemplation.
