Still Blood Armor! The Fifth Armament Haki Technique

The Power Gauge had a testing limit of 10,000.

With Rosen's Doriki Value of 260, it was impossible for him to exceed the Power Gauge's limit. But not exceeding its limit did not mean he could not destroy it.

He could send his Armament Haki through the Power Gauge's surface, into its interior, and destroy the components inside.

Those 260 Doriki could still destroy a Power Gauge with a testing limit of 10,000.

Zefa naturally saw this as well, which was why he was so shocked.

"I heard Teacher Zefa mention that besides coating, hardening, and Flowing Emission, Armament Haki also has a fourth technique."

"Internal Destruction."

"So when I released my Armament Haki outward, I tried controlling it to pass through an object's surface and directly destroy its interior."

Seeing Zefa's ghost-struck expression, Rosen could only explain.

"I only said the words 'Internal Destruction.'"

"And you went and mastered the fourth technique of Armament Haki on your own?"

Zefa's mouth fell open in shock.

It was like telling someone about an atomic bomb, only for them to actually build one with their own hands.

"More or less."

"Though I didn't entirely master it on my own."

"If Teacher Zefa hadn't mentioned Internal Destruction, I wouldn't have known Armament Haki could be used this way. So Teacher Zefa, you taught me well!"

Rosen nodded slightly.

"..."

Hearing This, Zefa's old face immediately reddened.

He had always taken incomparable pride in his teaching ability.

After all, he had taught three Admiral Candidates—monsters guaranteed to become Navy Admirals.

If anyone else said he had taught them well, Zefa would have accepted it calmly.

But when facing Rosen, he truly could not bring himself to say that it was because of his good teaching.

He knew very well that even if a marine from the New World who knew how to use Armament Haki had taught Rosen instead, the result would have been no different from being taught by a Navy Admiral like him.

Rosen's talent for cultivating Haki had reached the point where he could disregard a teacher's level entirely.

If a marine taught him, he would learn Armament Haki coating, hardening, emission, and Internal Destruction all in one lesson.

If a Navy Admiral taught him, he would still learn Armament Haki coating, hardening, emission, and Internal Destruction all in one lesson.

"What is it?"

"Is something wrong?"

"Did you accidentally hurt yourself while cultivating Armament Haki?"

Just as Zefa was about to say something, he noticed Rosen's slightly furrowed brow and hurried over to ask with concern.

This was an Admiral—no, a youngster with the potential to become a Fleet Admiral!

If Sengoku found out that he had injured such a promising Fleet Admiral seed during training, he would probably come charging into the Navy School with a Buddha's Palm.

"I didn't get hurt. I just had a sudden thought."

"Armament Haki can perform Internal Destruction, right? If an enemy can use that technique too and lands such an attack on me, how should I deal with it?"

"What do you think, Teacher Zefa?"

Rosen shook his head, then sought Zefa's advice.

He thought of the clash between Teacher Kai and Monkey D. Luffy.

Both had mastered the advanced Armament Haki technique of Internal Destruction, yet when facing each other's attacks, it seemed they could only endure the other's damage head-on.

"Only Armament Haki Can Against Armament Haki."

"If the enemy uses a technique like Internal Destruction, then before their Armament Haki touches your body, you can only release your own Armament Haki first to neutralize it. But battles change in an instant. If you've already been hit by the enemy's attack, that means you couldn't react in time. How could you possibly have enough time to mobilize an equal amount of Armament Haki in an instant and release it to cancel out the attack?"

"If you could do that, then you would have had more than enough time to dodge the enemy's attack. You wouldn't have been hit at all."

As a former Navy Admiral, Zefa gave Rosen an answer without hesitation.

"So I can only take the damage head-on?"

Rosen's brow furrowed even tighter.

He had eaten a Weapon Fruit, not an Azure Dragon, much less Nika.

He did not have such a huge health bar, Nor Did He have such ridiculously durable defenses.

"Have you forgotten?"

"What was the first thing I said in class?"

"Having Haki that surpasses everything is not enough. You must also possess the physique of a monster and the will of steel."

Zefa cast Rosen a glance.

The meaning was obvious.

The physique of a monster was meant to withstand the damage from Internal Destruction.

"So in the end, I still have to tank it."

"Teacher Zefa."

"Is there really no other way?"

Hearing that, Rosen frowned even more deeply.

"Unless, during battle, you don't care about the consumption of Haki at all and use Haki to harden your entire body at every moment. But if your Haki is spread across your whole body, your defenses will inevitably weaken."

"If the enemy attacks just one area, they can still break through your defenses."

"You might even lose to an opponent you could originally defeat because you consumed too much Haki."

Zefa shook his head.

"Don't dwell on these things. You're worried about the enemy's Internal Destruction, but the enemy is also worried about yours."

"Rather than fret over that, you should train your body and your physical techniques."

"That way, you can seriously injure the enemy before they even make a move."

He spread his hands.

Rosen secretly shook his head. He felt Zefa's method would not work.

It was fine for crushing weak opponents.

But against someone of the same level, who could guarantee they could KO the other person in one strike?

Take Teacher Kai, for example.

Who could empty Teacher Kai's health bar in one hit?

Big Mom?

Red-Haired?

Or Whitebeard?

The three of them together might be able to do it.

"Stop thinking about such nonsense."

"As far as I know, there is currently no effective way on the Grand Line to defend against Internal Destruction. Techniques like coating, hardening, and emission cannot do it."

"Neither the Four Emperors nor the Navy Admirals can effectively defend against attacks that come from inside the body."

Seeing Rosen's tightly furrowed brow, Zefa feared that he would get stuck in a dead end and sternly rebuked him.

"Coating, hardening, and emission can't do it."

"In that case, could I create a Haki technique specifically for countering Internal Destruction?"

"Teacher Zefa also said that only Armament Haki can counter Armament Haki. Techniques like coating and hardening were all created by those before us. That means Internal Destruction didn't exist in the past. Someone only thought of it later, and that was how it came into being."

At that thought,

Rosen's consciousness began to sink inward. He poured Armament Haki into his body, kneading and shaping it, trying to find a form—trying to find a technique specifically meant to counter an enemy's Internal Destruction.

As the Armament Haki within his body continuously transformed, his thoughts gradually emptied until he completely merged with it.

No one noticed.

His Armament Haki had actually begun to slowly flow into his blood vessels, circulating throughout his entire body along with his blood.

Your comprehension is heaven-defying. Using the four techniques of Armament Haki as a foundation and combining them with Haki Supreme Art, you have innovated and comprehended an Armament Haki Exclusive Skill: Still Blood Armor.

Still Blood Armor: With the absolute control over Armament Haki granted by Haki Supreme Art, inject Haki into the blood vessels and transform it into tangible defensive power. Greatly enhances the body's defenses both inside and out, effectively defending against abilities that destroy the body from within.

(Requires Haki Supreme Art. If others attempt to cultivate it, it will cause permanent damage to the blood vessels throughout their bodies.)

Suddenly.

A line of information flashed through his mind, jolting Rosen awake from his deep thoughts.
