One Piece: New Century Hextech Warriors

Something monstrous seemed to be stirring up the ancient ruins, with billowing smoke and sand rising up and covering half of the ancient city in the blink of an eye, making the already dark seabed look even more ferocious and terrifying.

Suddenly, Sith noticed a red light flashing within the gray smoke, and a wave of intense heat rushed towards him from a great distance.

He instantly realized what was below.

"Underwater volcano!"

Sith suddenly realized why Zephyr had asked the science unit to come down at the exact time; it turned out they were waiting for the underwater volcano to erupt!

"Has this old man gone mad?"

He glanced at Zefa beside him in surprise, only to see that the other man's expression was calm, but there was a hint of excitement in his eyes.

It was as if what rushed toward them was not lava and heat reaching thousands of degrees, but an old friend they had not seen for a long time.

"Siss, keep a close eye on him!"

Zefa grinned and then swam toward the terrifying force.

Sith didn't stop them, and simply stood by with his arms crossed, watching from the sidelines.

The strongmen on this sea are all madmen. Since our teacher dares to be so crazy, it means he has complete confidence.

Zephyr swam a few meters and stopped, his body hovering in the dark seawater. The Armament Haki covering his body was even blacker than the seawater.

Especially the Armament Haki on his right wrist, which was as thick as ink, and even from a great distance, Sith could sense the immense power contained within it!

Rumbling--

The underwater volcano was still roaring, and huge plumes of smoke and lava were already surging towards Zefa.

At that moment, Zephyr also moved.

He let out a roar comparable to that of a sea king, and his right fist slammed out with tremendous force, unleashing the full power of his Armament Haki, which had been condensed to the extreme.

Boom!

Zefa's fist collided with the magma, and the shockwave tore through the seawater, creating a spherical vacuum more than ten meters in diameter. Immediately afterward, a transparent wave of air spread out, and Sith saw several unfortunate sea monsters in the distance being directly knocked unconscious by the shockwave.

The surging magma was abruptly halted by this punch, roaring helplessly like an unwilling sea monster.

"Is Old Deng even human in this world?!"

Sith crossed his arms in front of him, and even with his body enhanced by the [Tank Engine], he felt waves of excruciating pain, and was pushed back dozens of meters.

But something even more surprising happened. Zefa's punch not only blocked the lava, but also seemed to unleash a second burst of force, shooting straight down.

Boom!

A dull, deafening roar came from below. The underwater volcano was forcefully suppressed by the impact, with lava and heat flowing back in. The erupting crater was flattened and shattered, forced to a halt.

A terrifying underwater volcanic eruption was extinguished by this one punch.

"Coach, I want to learn this!"

Witnessing this extraordinary sight, Sith couldn't help but exclaim in amazement.

People's physical constitutions cannot be generalized, and this is especially true of the domineering aura, which embodies human will and physical strength.

Some people's Armament Haki can extinguish underwater volcanoes, while others' Armament Haki can be instantly defeated by Guy's single blow.

Right, the invincible Kozuki Oden!

"How's it going, kid?"

Zephyr returned to Sith's side, his face beaming with smugness.

He has been busy with naval affairs and teaching students in recent years, and has not been here to cultivate for a long time.

After throwing that punch, I realized that my strength doesn't seem to have deteriorated much.

"Powerful! Dominant! Strong!"

Sith quickly gave a thumbs up and asked curiously:

"Zeff, that punch you just threw... you must have combined different powers, right?"

He genuinely admired Zephyr. This punch wasn't just a simple release of Armament Haki; it also incorporated internal destruction. Otherwise, it could at most force back the magma, but wouldn't be able to destroy the underwater volcano.

In other words, Zephyr's seemingly simple punch actually brought the power of Armament Haki to its limit!

Moreover, he observed an even more crucial point.

"Also, it seems that your punch delivered two forces at the same time. First, it stopped the erupting magma, and then the second wave of force completely suppressed the underwater volcano."

"There seems to be a time difference between these two forces; first, it breaks through the defenses, then it destroys, and finally it produces the greatest destructive effect."

As he was talking, he suddenly realized that this was very similar to "Black Flash".

The ability that Tiger developed allows the error between physical impact and magical impact to occur sequentially within a very short time, generating a powerful force that can distort space.

Zephyr's Armament Haki isn't as mysterious as some people think, but the basic principle is similar.

Upon hearing Sith's question, Zephyr patted his beloved disciple with great satisfaction.

"Haha! You're something else, kid! You figured out the key point right away!"

He pointed to the Armament Haki slowly flowing around his body and said seriously:

"Sis, in my opinion, the vast majority of people still haven't developed their Armament Haki enough!"

"To date, I still haven't found another person who can use Armament Haki like me, not even those three brats who became generals."

"I just don't understand. Even if someone is incredibly stupid, how could they not learn Armament Haki? With a little effort, they could reach my level, right?"

Sith secretly thought to himself that this sounded a lot like what a certain calculus professor said.

Is it possible that it's not that others are too weak, but that you, teacher, are too abnormal?

After all, in this world that values ​​fruits and bloodlines, being able to stand at the top of the world solely by relying on Armament Haki is no longer considered normal human behavior.

Zefa shook his head and continued:

"Many years ago, I heard that the samurai in Wano Country were very skilled in Armament Haki and had mastered a technique called 'Ryuo,' which allows Armament Haki to flow like water, greatly improving flexibility."

"Later, I tried to learn from them and made my Armament Haki flow, which made it much easier for me."

"Finally, I made a small improvement, allowing the Armament Haki to fuse with internal destruction when released externally, and then unleashing these two forces sequentially. This means that one attack can cause damage twice, increasing its power by at least two times!"

Sith listened to Zefa's explanation and felt that he had benefited greatly.

Zephyr's Armament Haki is indeed among the best, reaching a level where no one can compete.

If his student hadn't been killed, and if he hadn't witnessed the Navy's complete corruption, which shattered his resolve, and hadn't unfortunately encountered Luffy in the movie, his mastery of Armament Haki would probably have reached a godlike level.

Zephyr spent a long time explaining the principles and techniques, and finally said to Sith earnestly:

"Siss, I haven't found a student who can compare to me all these years. Those guys can't even withstand the water pressure here."

"But you're an exception!"

His eyes shone with light, as if he had found a treasure he had been searching for for many years.

"This ancient site contains many underwater volcanoes. I will accompany you here to train for a while. You will be considered a master when you can shatter an erupting volcano!"

Sith was deeply moved; the old man truly treated him like his own son.

Suddenly, something occurred to him, and he asked expectantly:

"Zeff-sensei, what's this move called?"

Such powerful Armament Haki must have a really cool name.

Zefa scratched his head.

"Um, I haven't thought about that yet. How about we call it Super Invincible Berserk Armament Haki?"

Sis was speechless, thinking that the teacher's naming skills were comparable to those of the blond-haired kid from the next village.

"How about we call it Black Flash?"

He offered suggestions.

His abilities are very similar to Black Flash's, and they also fit the nickname "Black Arm Zephyr".

Zefa laughed heartily:

"That kind of thing is fine, anyway, you're my only successor, you can call me whatever you want!"

"As for now—"

He grinned maliciously as he looked at another underwater volcano that was about to erupt.

"Go, put it out!"
