Weapon fruit is rubbish? Have you ever heard of Ryujin Jakka?

The test limit of the Dao Force Device is.

With Rosen's Dao Power value of 260, it is impossible for him to exceed the upper limit of the Dao Power Device. However, not exceeding the upper limit of the Dao Power Device does not mean that the Dao Power Device cannot be destroyed.

Use the Armament Haki to penetrate the surface of the Dao Power Device, enter its interior, and destroy the parts inside.

That Dao force value of 260 can still destroy a Dao force device that has reached its test limit.

Zefa naturally also saw this, which is why he was so shocked.

"I saw that you just mentioned that in addition to the entanglement hardening and flow release of Armament Haki, there is a fourth technique."

"Sabotage from within."

"Then, when I release my Armament Haki, I try to manipulate it to pass through the surface of the object and directly destroy the inside."

Seeing Zefa's expression as if he had seen a ghost, Rosen could only explain.

"All I said was internal sabotage."

"You mastered the fourth technique of Armament Haki by yourself?"

Zefa was so shocked that his mouth opened.

It's like you say the word "atomic bomb" to someone, and then the other person really rubs the atomic bomb with his hands.

"That's about it."

“But it’s not all my own doing.”

"If it weren't for your words about internal destruction, Mr. Zephyr, I wouldn't have known that Armament Haki could be used this way, so Mr. Zephyr is still a good teacher!"

Rosen nodded slightly.

"..."

When Zefa heard this, his old face suddenly turned red.

He has always taken immense pride in his teaching abilities.

After all, he had trained three candidates for generals, and they were the kind of monsters who would definitely be promoted to generals.

If anyone else said that he taught well, Zefa would definitely accept it calmly.

But facing Rosen, Zefa was too embarrassed to say that it was because of his good teaching.

He knew very well that even if a marine who knew how to use Armament Haki came to teach Rosen in the New World, the final result would be no different from what he, the great future leader, would teach.

Rosen's talent for cultivating his domineering aura has reached a level where he can ignore his teacher's teaching level.

A Marine came to teach him, and he learned all the armament color entanglement, hardening, external release and internal destruction in one class.

The great future will teach, he also learned the full armed color entanglement, hardening, external and internal destruction in one class.

"how?"

"Is there anything wrong?"

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

Zefa was about to say something, but found that Rosen frowned slightly, so he hurried forward and asked with concern.

This is a great general, no, he is a potential marshal!

If Zhan Guo knew that he had injured such a young marshal while teaching, he would probably come to the Naval Academy with the Tathagata Palm to attack.

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

"Can't Armament Haki destroy from within? If the enemy also has this skill and attacks me like this, how should I respond?"

"Teacher Zefa, what do you think?"

Rosen shook his head and asked Zefa for advice.

He thought of the fight between Teacher Kai and King Luffy.

Both of them have mastered the advanced technique of Armament Haki such as internal destruction, but when facing each other's attacks, it seems that they can only choose to take the damage from the other side?

"The only thing that can counter Armament Haki is Armament Haki."

"If the enemy uses a technique like internal destruction, you can only release the Armament Haki to counteract it before the opponent's Armament Haki touches your body. But battles are ever-changing, and if you are attacked by the enemy, it means you can't react at all. How can you have enough time to mobilize a completely equal Armament Haki in an instant and then release it to counteract it?"

"If you can do that, that's more than enough time to dodge the enemy's attack and not get hit at all."

As a former navy admiral, Zefa answered Rosen's question without hesitation.

"So, we can only take the damage?"

Rosen frowned even more.

What he ate was the weapon fruit, not the Azure Dragon, nor was it Nika.

The health bar isn't that thick, and the defense isn't that durable.

"Did you forget it?"

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

"It's not enough to possess the domineering aura that overrides everything. You must also possess the physique of a monster and the will of steel."

Zefa glanced at Rosen.

The meaning is self-evident.

The monster's physique is meant to withstand the damage caused by internal destruction.

"After all, we still have to bear it."

"Teacher Zefa."

"Is there no other way?"

When Rosen heard this, his brows furrowed even more.

"Unless you don't care about the consumption of your domineering aura during the battle and use it to harden your entire body all the time, but if your domineering aura is dispersed throughout your body, your defense will inevitably decrease."

"The enemy only attacks one area of ​​your defense, but it can still break through."

"Even if you do this, an opponent who could have won will lose because you consume too much Haki."

Zefa shook his head:

"Don't think about it. You worry about the enemy's internal sabotage, and the enemy also worries about your internal sabotage."

"Instead of worrying about these things, it is better to train your body and physical skills well."

"In this way, you can severely injure the enemy before he attacks."

He spread his hands.

Rosen shook his head secretly, thinking that Zefa's method didn't work.

It’s okay to bully weak players.

When facing an opponent of the same level, who can guarantee to knock out the opponent with one blow?

Take Teacher Kai for example.

Who can clear Teacher Kai’s health bar with one strike?

Big Mom?

Red hair?

Or Whitebeard?

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

"Don't think about these things."

"Anyway, as far as I know, there is currently no means on the Grand Line that can effectively resist internal damage. Entanglement, hardening, or external release techniques are all ineffective."

"Neither the Four Emperors nor the Admirals can effectively defend against attacks from within the body..."

Seeing Rosen's frown, Zefa was afraid that he would get stuck in a rut, so he shouted at him.

"Entanglement, hardening, and externalization are all not acceptable."

"In that case, can I create a domineering technique specifically for fighting internal destruction?"

"Teacher Zephyr also said that only Armament Haki can counter Armament Haki, and techniques such as Entanglement Hardening were created by our predecessors. In other words, there was no internal destruction before, but someone thought of it later, so it came into being."

Think of this.

Rosen's consciousness began to sink, and he poured the Armament Haki into his body, rolling it into a ball and flattening it, trying to figure out a shape, trying to figure out a technique that could be used specifically to counter the enemy's internal destruction.

As the Armament Haki continued to change in his body, his mind gradually emptied and completely merged with the Armament Haki.

No one found out.

His Armament Haki actually began to slowly flow into his blood vessels, circulating throughout his body along with the flow of blood.

[You have an extraordinary understanding. You have combined the four techniques of Armament Haki with the Ultra Instinct to create an innovative and unique skill for Armament Haki: Static Blood Suit.]

[Still Blood Suit: Using the absolute control of the Armament Haki with the Ultra Instinct, the Haki is injected into the blood vessels to transform it into a substantial defensive force, greatly improving the defense inside and outside the body, and can effectively defend against the ability to destroy from within the body.]

(Requires the ultimate power of domineering intention. If others practice it, it will cause permanent damage to blood vessels throughout the body.)

……

Sudden.

A line of information jumped out of his mind, waking Rosen from his deep thought.
