One Class, Learn All Entanglement, Hardening, External Release, Internal Destruction

"Rosen."

"Come with me."

After calling Kizaru to substitute, Teacher Zefa immediately beckoned Rosen and left the classroom with him, arriving in a room furnished with several wooden dummy-like training equipment, but made of steel.

"This is an instrument created by the head of the Marine Science Division, Vegapunk, to test Haki values."

"The upper limit is 10,000."

"With this, students can clearly see their own progress in the early stages."

Teacher Zefa pointed to a Haki instrument:

"What you need to do now is use your Haki and hit the Haki instrument with your full power."

He crossed his arms and looked at Rosen.

"Okay."

Hearing this, Rosen's consciousness immediately poured into his Haki. He wrapped all the Armament Haki in his body around his right arm, hardening his fist and forearm together.

Then, he lunged forward, his spine like a bowstring, his fist like an arrow, and struck out fiercely.

The moment his fist hit the Haki instrument, a string of numbers immediately jumped on a small display screen.

260.

"Not bad. According to the World Government, learning Rokushiki and having Haki exceeding 500 means you are a superhuman."

"You currently lack offensive Physical Techniques, but with your newly awakened Armament Haki, you can still unleash 260 Haki in one strike, equivalent to half a superhuman."

"By the way, a well-trained Marine, with a weapon, would only have about 10 Haki."

Teacher Zefa explained the significance of 260 Haki.

"Do you understand?"

"This is where the power and value of Haki lie."

Teacher Zefa said with a solemn expression.

Obviously.

The reason for having Rosen throw this punch was, in the final analysis, to make Rosen value Haki.

"I understand, Teacher Zefa."

Rosen nodded.

Without Zefa saying it, he also knew the importance of Haki.

After Zefa's personal demonstration and his own experience, he felt even more deeply the value of Haki.

He, who couldn't even use the Six Powers and had only just awakened Armament Haki, was able to unleash half of a Superhuman's Dao power value solely through the absolute control of Armament Haki from the Haki Extreme Art.

This is Armament Haki.

"If I use Thousand Cherry Blossoms and then wrap Armament Haki around it, I wonder how much Dao power it would be?"

At this moment, a thought sparked in Rosen's mind.

Manually creating Thousand Cherry Blossoms and then applying Armament Haki.

This is the correct way to utilize a Paramecia Ability.

"Good, you understand."

"Then."

"There's one more thing."

Zefa released his arms clasped at his chest, then clenched his fists. Armament Haki wrapped around and hardened, his fist like a dark cannonball, he punched out.

The air at the front of his fist seemed to be compressed to the extreme, then, unable to bear the pressure, it exploded with a roar.

A tangible Haki impact erupted from his fist, striking the Dao Power Meter across the distance, directly crushing the Dao Power Meter, which had a testing limit of 10,000, into a metal disc.

"Did you see that clearly?"

Zefa turned his head to look at Rosen.

"Flowing Emission."

Rosen's eyes brightened, but his heart was very calm.

Relying on Heaven-Defying Comprehension, the moment he grasped the Haki Extreme Art, he was already able to control Armament Haki at will.

In other words.

Coating, Hardening, Emission, and Internal Destruction.

These four techniques, he could use them after seeing them once, and even with a little exploration, he could master them within a few minutes.

This is the value of the Haki Extreme Art.

Just as Life Return allowed him to control his body at will, Rosen, through the Haki Extreme Art, could also control Armament Haki at will after infusing his consciousness into it, using various techniques.

"Not bad."

"It's Flowing Emission."

"This is also the third Armament Haki usage technique I want to teach you."

Teacher Zefa first nodded, but immediately shook his head again:

"However, this is not all."

"Look at the Doryoku Device."

"My punch and your punch, besides the Flowing Emission technique, what else is different?"

He looked at Rosen with burning eyes.

"Armament Haki techniques have levels, but they represent the strength of Armament Haki, not the strength of power."

Rosen's mind turned, and he immediately thought of the knowledge point Teacher Zefa wanted him to understand.

"Not Bad."

"Besides Coating and Hardening, and Flowing Emission, Armament Haki also has the Internal Destruction technique, but even if you learn all four techniques, it only represents that your Armament Haki has multiple ways of use."

"It's like a sword, it can chop, it can stab, it can slash, but no matter how you use it, the hardness and sharpness of this sword itself remain unchanged."

A hint of satisfaction flashed in Teacher Zefa's eyes:

"Don't be superstitious about Armament Haki techniques, you should focus on improving the strength of Armament Haki."

"Take you and me as an example, even if you use all four Armament Haki techniques, and I only use the most basic Coating, I can still kill you with one punch."

"This is the qualitative gap in Armament Haki between you and me, which no technique can make up for."

He said word by word.

"I will remember your advice."

"Teacher Zefa."

Rosen nodded seriously.

He agreed with Teacher Zefa's statement.

Monkey D. Luffy (he) is the best example.

Observation Haki can predict the future.

Armament Haki can coat, harden, and also emit and internally destroy.

Instant God Conqueror's Haki can also achieve coating.

In the end, I still couldn't beat Teacher Kai.

Fundamentally, besides the difference in physique, the most crucial factor was the gap in Haki strength.

In terms of technique, Monkey D. Luffy had kept up with Teacher Kai, but not with the quality of his Haki.

"Go ahead."

"First, master Flowing Emission, and then I'll teach you Internal Destruction."

"Once you've mastered all four techniques of Armament Haki, I'll teach you how to increase its strength."

Just as Teacher Zefa was about to explain the techniques and tips for Flowing Emission, Rosen raised his hand and extended a finger.

With a whistling sound that broke through the air, a Haki shockwave erupted from his fingertip, striking a Doryoku Device not far away.

Of course.

It didn't shatter the Doryoku Device from a distance like Teacher Zefa had, it only registered a Doryoku value of 260.

"As expected."

"Just as Teacher Zefa said, Armament Haki techniques don't equate to strength."

"Whether using Hardening or Flowing Emission, the Doryoku value output is the same."

Seeing this, Rosen couldn't help but sigh that it was good to have a famous teacher guiding him; there was no possibility of taking a detour.

"You've learned Flowing Emission?"

Teacher Zefa's eyes widened in shock.

As a former Navy Admiral, he knew very well that among the techniques for using Armament Haki, Flowing Emission was much more difficult to learn than Hardening.

Yet, he had only thrown one punch, and his student had already mastered it. Not only that, but he used it without any awkwardness, instead giving the impression of someone who had practiced for many years.

"I've learned it."

Rosen nodded.

"Not just Flowing Emission."

"Even Internal Destruction, which Teacher Zefa just mentioned."

"I've learned that too."

Before Teacher Zefa could speak, he dropped another bombshell.

"Impossible."

As Zefa's voice fell, a sound of metal cracking came from not far away.

He turned his head and saw that the Doryoku Device, which Rosen had just attacked remotely with Armament Haki, was actually making cracking sounds from within. Simultaneously, the number 260 on the display became blurry and finally disappeared.

"Internal Destruction?"

"I haven't used it in front of you!"

"How did you do it?"

Zefa muttered to himself.

Entanglement, Hardening, Emission, Internal Destruction.

In one class period, Rosen had learned all four techniques of Armament Haki.

Especially Internal Destruction, the most profound Armament Haki technique, he had even figured it out on his own.
