You Were Told to Learn Life Return, but You Created Six Warehouses Immortal Thief?

"It seems."

"He's about to improve again."

Seeing Rosen like this, Zefa couldn't help raising a hand to his forehead.

Just now in the cafeteria, he had asked Rosen to give a simple self-assessment, only for the latter to directly comprehend a sixth Armament Haki technique.

Moving Blood Armor.

And now on the beach, he had merely told Rosen to train the Six Styles and Life Return, yet he was already pulling something new again.

Honestly.

He was known for being strict and demanding extremely high standards from his students. Even someone as strong as Borsalino, in his eyes, was still too specialized, not hardworking enough, and overly reliant on the Glint-Glint Fruit.

But Rosen was absolutely not included in that.

To be fair, Zefa felt that every aspect of Rosen could only be described as perfect. There was really no need for him to keep comprehending things at the drop of a hat and deducing new abilities whenever he felt like it.

"I just wonder what astonishing ability he'll comprehend this time."

Although Zefa felt that Rosen did not need to improve so quickly, he was also immensely curious about what kind of surprise his student would bring him this time.

Your comprehension is heaven-defying. Using Haki Supreme Art as your foundation, you contemplated the essence of Haki and combined it with Zefa's explanation, successfully deducing an exclusive physical technique: Six Warehouses Immortal Thief.

Six Warehouses Immortal Thief: With Haki Supreme Art's absolute control over Haki, Armament Haki is infused into the gallbladder, stomach, small intestine, large intestine, bladder, and triple burner respectively, strengthening the body's six hollow organs. Using this as a foundation, it creates a perfect digestive system capable of perfectly absorbing nutrients, improving one's physique, eliminating body odor, and preventing the body from aging, preserving one's peak state forever.

(Requires Haki Supreme Art. If anyone else trains it, their six hollow organs will rupture and they will die.)

Rosen did not make Zefa wait long.

About half an hour later, a stream of information surfaced in his mind.

The instant Six Warehouses Immortal Thief was created, he had also completely mastered everything about it.

"Now I won't have to worry about nutrition failing to keep up, causing my Haki training to suffer while my body becomes depleted."

"Whether it's Haki training or physical training, Six Warehouses Immortal Thief's ability to digest and absorb matter can fully support both at once, with plenty left over."

"Most importantly, I won't age anymore. I'll remain at my peak forever."

A trace of amusement flashed through Rosen's eyes. Then he infused Armament Haki into his six hollow organs. In an instant, the digestive system within his body became like a gluttonous beast that could never be filled, instantly digesting and perfectly absorbing anything it ate.

There were many substances in the pirate world that contained extremely high nutritional and energy value, yet ordinary human bodies could not digest or absorb them. But from now on, once he ate such substances, he could digest them completely, turn them into nutrients, and let his body absorb them perfectly without leaving anything behind.

At that moment, the food residue within his body was being rapidly digested, leaving nothing behind.

His body odor was also disappearing.

Even someone with a sense of smell ten or a hundred times sharper than a hunting dog would find it difficult to detect any scent from him.

And that was not all.

Through this perfect digestive system within his body, Rosen could instantly break down food—or rather, matter—that entered his body, then convert the nutrients he absorbed into Haki through circulation.

No matter how severe his injuries were, as long as he still had a breath left and could still breathe, he could recover completely through Six Warehouses Immortal Thief.

In short.

He could grow stronger and heal injuries even by eating air.

Combined with Qi Body Origin Flow, the Three-Color Qi Infant trained without interruption for twenty-four hours a day, causing the Three Colors of Haki to improve at a soaring speed.

"Not just Haki."

"I haven't even started physical training yet, but my physique is already getting stronger."

Rosen keenly noticed that after mastering Six Warehouses Immortal Thief and creating a perfect digestive system, his absorption and digestion had become so perfect that, with a massive supply of nutrients, not only was his Haki soaring, but his body was also growing stronger on its own.

It could be said that even if he stopped all training and combat from this day onward, as long as he did not skip his three daily meals, the strength of his Three Colors of Haki would skyrocket wildly. At the same time, his body would continuously grow stronger through Six Warehouses Immortal Thief's perfect ability to digest and absorb food—no, matter.

"Rosen."

"Your aura is rising."

"What's going on?"

Zefa seemed to have sensed the changes in Rosen. A red gleam flashed through his eyes as Observation Haki spread out, and he actually discovered that his student's aura was slowly increasing.

"Teacher Zefa, didn't you just say that after mastering Life Return, one can infuse consciousness into any organ or tissue in the human body? From internal organs down to strands of hair, everything can be controlled at will?"

"So I was thinking, could I use that as a foundation and combine it with Haki to create a physical technique even stronger than Life Return?"

"So I tried infusing Armament Haki into the large intestine, small intestine, stomach, triple burner, gallbladder, and bladder to see if I could create a perfect digestive system."

"As it turned out, I really succeeded. I created an ability that counts as both a physical technique and an Armament Haki technique."

"I call it Six Warehouses Immortal Thief."

Faced with Zefa's concern, Rosen did not hide anything.

After all, whether it was the Haki techniques or physical techniques he created, they were all his exclusive abilities.

Even if he were willing to teach them to others, anyone who trained them would die. Not even the Op-Op Fruit combined with a healing fruit could save them.

Take Still Blood Armor and Moving Blood Armor, those two Armament Haki techniques, for example.

Infusing Armament Haki into tiny, fragile blood vessels to develop offensive and defensive power.

Who would dare play with something like that?

With the power of Armament Haki, all the blood vessels in one's body would burst apart in an instant.

"I told you to learn Life Return, and you created Six Warehouses Immortal Thief?"

Zefa almost instantly understood how heaven-defying Six Warehouses Immortal Thief was. But precisely because of that, his feelings were extremely complicated.

It was like a middle school student whose teacher was preparing to give him his first physics lesson, only to find him handcrafting an atomic bomb—and actually succeeding.

"You should just train Six Warehouses Immortal Thief by yourself."

"Like Still Blood Armor, Moving Blood Armor, and those other abilities, don't try to teach it to anyone. Infusing Haki into organs like the large intestine, small intestine, stomach, triple burner, gallbladder, and bladder will kill someone one hundred percent of the time."

"No matter how close you are to them, don't teach it to them unless you want them dead."

In the end.

Zefa could only remind Rosen that he must never teach any of his self-created abilities to anyone.

As a former Navy Admiral, Zefa only needed to hear Rosen explain the principles of Six Warehouses Immortal Thief once to understand just how heaven-defying his student's self-created ability was. It surpassed Life Return by more than a hundred times, but because it was too heaven-defying, it could not be widely taught and could only be used by Rosen alone.

As for anyone else, whether they were Nika or Azure Dragon, anyone who trained it would die.

There would be no exceptions.

"I understand."

Rosen naturally knew just how heaven-defying the abilities he had created were.

But precisely because they were too heaven-defying, they had all become Exclusive Skills.

He was more than happy with that.

That way, even if the Five Elders coveted the abilities he had created one day, they would never entertain any crooked thoughts.

Unless they wanted everyone in the World Government dead.

"Since you created Six Warehouses Immortal Thief, the problem of training both Haki and physical techniques has been completely resolved."

"Then."

"I'll teach you the Six Styles now."

Zefa shook his head, calming the shock in his heart, before demonstrating the Six Styles in front of Rosen.
