In a spacious classroom at Marineford Military Academy, thirty cadets from Class One gradually found their seats and sat down. Since most of them had run over a hundred kilometers in the morning, the short lunch break was far from enough to eliminate all their fatigue. As a result, many of them were yawning and looking listless, lying on the desks and dozing off.
According to the academy's curriculum, they would have pure physical training every morning from now on, and in the afternoon, they would take various courses such as military theory, navigation, swordsmanship, and so on.
Dinglinglingling...!
As the class bell rang, Zephyr with purple hair and Sousuke with a long ponytail walked into the classroom.
Bang!
Without saying a word, Zephyr slapped the podium with one hand, causing the blackboard eraser and chalk box on the table to jump high.
"Stop sleeping! Otherwise, you'll have to run two hundred laps on the playground for me."
As soon as he said this, the effect was immediate. Kaji, Smoker, Maynard... Those who were originally lying on the desks, half - asleep, all sat up straight, widened their eyes, and looked energetic and valiant.
"In this afternoon's class, I'll explain to you our Navy's body technique, the Six Styles, and the power of the two - colored Haki that you'll be eligible to master only after you've fully mastered the Six Styles."
As he spoke, Zephyr actually took out a snail - shaped Den Den Mushi from his trouser pocket and placed it on the podium. He just reached out and pressed the snail's shell, and two beams of light were projected onto the blackboard, forming a simple slide show.
"Shit! They've really come up with all sorts of uses for the Den Den Mushi in this world..." Sapphire watched the projection on the blackboard and muttered to himself.
There are so many types of Den Den Mushi in this world: live - broadcast Den Den Mushi, photo - taking Den Den Mushi, eavesdropping Den Den Mushi, anti - eavesdropping Den Den Mushi, recording Den Den Mushi... There are simply too many to count!
For this reason, a discipline dedicated to researching and developing Den Den Mushi has even emerged!
"The Navy's Six Styles: Finger Pistol, Tiger - Step Kick, Shave, Paper - Drawing, Moonwalk, Iron Body.
This is a set of techniques developed to surpass the physical limits of humans.
Once you master the Six Styles, you'll have the power to fight even against Devil Fruit users.
All the physical training programs at the academy are designed to help you master the Six Styles. For example, during your long - distance run this morning, you could try to use the Shave technique to accelerate...
The Six Styles have great potential. After you've fully mastered them, you can derive various combat techniques from them..."
As he spoke, Zephyr pointed at Sousuke standing beside him.
"Show them your Life Return."
Hearing this, the long - armed man nodded and let out a soft shout:
"Life Return!"
Immediately, the long ponytail on Sousuke's head seemed to come to life, writhing in mid - air and forming a palm made of hair.
The 'black hair hand' quickly picked up the chalk on the podium and scribbled Life Return on the blackboard.
Seeing this, Domino, a sweet - looking and lovely girl with long golden curly hair sitting in front of the podium, couldn't help opening her small mouth slightly and exclaiming,
"Wow! This should be a Devil Fruit ability, right?"
Hearing this, Zephyr laughed and shook his head.
"No! He just infused his consciousness into his hair, thus being able to control it freely.
Similarly, as long as you master the Six Styles to a high level, you can freely control your body's muscles, internal organs, skin and other organs.
Once you can do this, it'll be a breeze for you to master Armament Haki or Observation Haki by drawing on what you've learned.
It can be said that the Navy's Six Styles are designed to help you lay a good foundation for using Haki. Through systematic training, you can more easily awaken and master the power of Haki.
Of course, this doesn't mean that the Navy's Six Styles are inferior skills to Haki.
The Six Styles and Haki complement each other, and when combined, they can unleash great power."
"Whether it's me, Vice Admiral Garp, the Navy Hero, or Fleet Admiral Kong, we can all rely on the power of the Six Styles and Haki to crush most of the powerful fighters and Devil Fruit users in the world.
Moreover, as long as your Haki is strong enough, you can even be immune to the effects of certain Devil Fruits."
Seeing that the students in front of the podium still looked unimpressed, and some of them were even dozing off and not paying attention, Zephyr could only sigh helplessly.
To be honest, he also found it annoying to teach theory!
The cadets he'd selected for the Star Cadet Class over the years were all quite strong and had great potential.
However...
Their educational levels varied greatly. Some of them had a good education, with clear - thinking and wide knowledge, while others had never been to school and could barely write their names.
This was the difference brought about by their backgrounds. The rich kids got elite education, while the poor kids didn't even have a chance to be educated.
Such was the backdrop of the era, and Zephyr was powerless to change it.
Therefore, the cultural courses, which were added to the curriculum of the Naval Academy at the suggestion of Admirals Sengoku, often showed a polarization in grades.
As a result, the cultural course grades could only serve as a reference for evaluating the students' talent and potential, not as the graduation standard.
"Shuso, go to the equipment room and bring a ten - centimeter thick steel plate here."
"Yes!"
The long - handed and strong Shuso nodded and quickly ran out of the classroom.
A little later, Shuso carried a steel plate that was one and a half meters wide and three meters long into the classroom.
Bang!
Shuso just dropped the steel plate weighing over three thousand kilograms. It landed heavily on the ground, causing the whole classroom to vibrate slightly.
"I, the old man, have a nickname, 'Black Wrist'. The reason I got this title is that with these arms of mine, using the Iron Block and Haki, I've defeated many well - known big-time pirates."
As he spoke, Zefa's entire right arm was instantly covered with black Armament Haki. He let out a fierce shout, swung his right fist and forcefully punched the large steel plate that was being supported by Shusui.
Boom!
With the stunned expressions of the cadets below the podium, Zefa's entire right arm actually penetrated through the large steel plate. His fist stopped within a hair's - breadth of Shusui's chest.
Gulp!
Is this guy really a human being?
Such a thought popped into the minds of the cadets one after another.
Looking at the large steel plate penetrated by Zefa with hardly any bending or deformation, Sephiroth couldn't help but think more deeply.
How much penetrating power is needed to instantly pierce through the steel plate without deforming it? Moreover... it was obvious that his fist stopped the forward inertia in time before reaching Shusui's chest!
Can one possess extremely strong destructive power and achieve precise control at the same time?
Seeing the shocked expressions of his students, Zefa calmly withdrew his entire right arm and said in a calm tone:
"This is the power of combining Six Styles with Haki. When you can reach the level of me, the old man, you can also be considered a powerful figure on this sea."
After hearing Zefa's words, the cadets below the podium were all inspired and began to listen attentively.
However...
Fifteen minutes later.
"Smoker, Kaji, Prince Grus... You brats actually dare to sleep in my, the old man's class. Get out and run two hundred laps!!!" Zefa slammed his fist hard on the podium and roared loudly.
The cadets below the podium were already extremely exhausted. When Zefa was talking about the dull and hard - to - understand theoretical content, even if they didn't fall asleep, most of them just let the words go in one ear and out the other, and not many were really listening carefully.
But...
There was one exception!
As Sephiroth listened to the old man Zefa's theoretical teachings, he recalled the Armament Haki training method on Amazon Lily. Combining it with the medical knowledge he knew, a bold idea suddenly came to his mind!
This Armament Haki is so similar to the qi (vital energy) and internal strength mentioned in those martial - arts novels of his past life. He felt that he could conduct some research along this line of thought...
Let's be more down - to - earth first. Forget about creating some kind of divine skill for now, but advancing the Haki training method on Amazon Lily, he thought it was quite promising!
