Physical Techniques Class? First, a Wave of Heaven-Defying Comprehension

"Is my Moving Blood Armor not good enough?"

"Teacher Zefa."

Seeing Zefa remain silent, merely staring at him blankly, Rosen couldn't help but ask.

He had thought that the Moving Blood Armor he had comprehended was still some distance from the standard answer in Zefa's mind.

After all, Zefa was a former Navy Admiral and was known for being strict with his students. It was only natural for him to hold high standards.

"No."

"Your Moving Blood Armor is very good."

Could Zefa possibly say it was bad?

Since Armament Haki had first been discovered, more than a thousand years had passed. Generation after generation of kings and heroes had spent all that time developing only four techniques.

And Rosen?

In just two days, he had comprehended two Armament Haki techniques.

A large portion of that time had even been spent learning the Three Colors of Haki.

Even someone as demanding as Zefa had to marvel inwardly.

Other students were too eager to improve.

Rosen alone was improving far too quickly.

"Rosen, you need to understand one thing. I am not a wooden board that will just stand there and let you hit me."

Zefa racked his brains, trying to steer the conversation toward Physical Techniques.

"You have Haki techniques."

"You also have a method that combines offense and defense."

"What do you think you are still lacking?"

He looked at Rosen.

"Speed?"

"No."

"Physical Techniques."

Rosen shook his head, then tried offering an answer.

"Not bad."

"What you lack right now are the most basic Physical Techniques."

"Training Physical Techniques will not only give you ways to fight enemies, but also comprehensively improve your attacks, speed, defense, evasion, and other abilities. At the same time, training Physical Techniques also trains your body."

"It is a mutually reinforcing process."

Zefa smiled approvingly.

"Remember this."

"The stronger your physique, the stronger your physical techniques, and the stronger your Haki."

"If you want to stand at the pinnacle of the seas, neither Haki nor Physical Techniques can be neglected."

"Garp and I are the best examples."

To emphasize the importance of Physical Techniques, he directly used himself and Garp as examples.

"So the class you are teaching this afternoon is Physical Techniques."

Rosen understood.

He did not resist learning Physical Techniques.

Who would ever complain about having too many abilities?

Besides, strength in only a single field was not what Rosen wanted. Becoming a well-rounded fighter was his goal.

After all, having a weakness in one area meant there was a weakness to exploit.

He did not want to one day stumble because of Physical Techniques.

In any case, training Physical Techniques was only a matter of one class.

"Not bad."

Seeing that Rosen was not resistant to training Physical Techniques, Zefa felt relieved.

What he feared most was Rosen turning out like Borsalino.

Overly specialized.

Rosen specialized in the Three Colors of Haki, while Borsalino specialized in his Paramecia Ability.

After resting in the office for a while and waiting for their food to settle.

Zefa first called over a Military Academy teacher and had Gion and Tokikake taken to the place where they trained Observation Haki. Then he personally brought Rosen to a beach near Navy School.

"Next, I will teach you a type of Physical Technique known as the Six Powers."

"Finger Pistol, Tempest Kick, Tekkai, Shave, Geppo, and Kami-e."

"The Six Powers combine attack, defense, speed, and evasion. They can kill enemies and temper the body."

Zefa explained the various techniques of the Six Powers in detail.

"Of course, that is not the most crucial part."

"The most important thing is that after mastering the Six Powers, you can go a step further and master a Physical Technique called Life Return. It allows you to pour your consciousness into any tissue and organ in your body, freely controlling your body, hair, and even internal organs."

"Once you master Life Return, you can eat twice, or even several times, as much food as you ate today, then quickly digest it and absorb its nutrients."

"The Six Powers excavate your potential, while Life Return replenishes your expenditure."

"Only by complementing each other can they make you stronger and stronger, rather than training your body into ruin."

Hearing Zefa say that, Rosen's brow furrowed unconsciously.

"What is it?"

Zefa immediately noticed Rosen's unusual reaction.

"It is like this, Teacher Zefa."

"Didn't I previously comprehend a method for training Haki?"

"It can increase Haki strength through battle, and it can also increase it through training. But so-called training is actually just absorbing my body's energy or the nutrients in food to increase the strength of the Three Colors of Haki."

Rosen spread his hands.

"In other words, aside from the nutrients from food needed to sustain my body, I feed all the rest to the Three Colors of Haki."

"If I train Physical Techniques, then the nutrients from food must be prioritized for my body to replenish what is consumed after body training."

"In that case, my training progress in the Three Colors of Haki will slow down. It is not that I doubt Life Return, but can it really support the strengthening of both Haki and the body at the same time?"

Training the Three-Color Qi Infant also required nutrients. It did not make Haki stronger out of thin air.

But he only had one mouth and one stomach. There was simply no way for him to supply both his body and the Three-Color Qi Infant at once.

"This..."

"How about you try training the Six Powers once first?"

"Perhaps Life Return's ability to digest and absorb food will be enough to support both training the Three Colors of Haki and training Physical Techniques?"

Hearing this, Zefa's brow furrowed as well.

In his previous teaching experience, generally speaking, as long as someone mastered Life Return, four meals a day were absolutely enough to provide the nutrition needed for training both Physical Techniques and Haki.

Even Borsalino, Sakazuki, and Kuzan had been no exception back then.

But Rosen had comprehended the Qi Body Origin Flow.

He had directly planted the Three Colors of Haki in his upper, middle, and Lower Dantian, forming Three-Color Qi Infants that trained on their own twenty-four hours a day, frantically grinding Haki.

Even cultivation required spiritual energy, let alone Haki.

Back in the cafeteria, Rosen had already understood.

Other than during battle, the Three-Color Qi Infants trained constantly, every moment of every day—not only while he was eating.

It was just that when he ate, massive amounts of food entered his stomach and intestines. With his body receiving enormous nutrients, the Qi Infants' training speed would increase.

"That will not do."

"Sharpening the knife does not delay the chopping of wood."

"The most urgent matter, in my opinion, is to solve the nutrition problem first."

Out of caution, Rosen did not immediately begin training the Six Powers.

It was not because he worried that he could not master the Six Powers or Life Return. Rather, he did not have much confidence in Life Return's capabilities.

The Three-Color Qi Infants trained continuously around the clock to strengthen his Haki. They alone were already three enormous consumers.

If he also trained Physical Techniques, his body would need an enormous supply of nutrients as well. Otherwise, the more he trained, the more he would deplete himself.

He felt that relying solely on Life Return's absorption and digestion could not possibly satisfy the needs of both the Three Colors of Haki and his body's growth.

His Qi Body Origin Flow training would slow down in no time, and he might even train his body into a deficit.

If he wanted both Physical Techniques and Haki.

Rosen believed it was not impossible. The first priority was solving the problem of digestion and absorption.

"I only have one mouth and one stomach."

"It is impossible to conjure several more mouths and stomachs out of thin air."

"Then I can only strengthen the six original organs in the human body that absorb energy, just as Monkey D. Luffy uses Armament Haki to increase rubber's elasticity."

Having made his decision, Rosen sat directly on the beach and began thinking without a care for anyone around him.

Before class even began, he was going to make use of his Heaven-Defying Comprehension first.
