One Piece: Starting from Awakening the Cosmo at Marineford

Learning swordsmanship? That's not impossible.

After all, this body was originally a swordsman, although his level was very low and his sword skills were quite ordinary.

Moreover, having more skills is never a bad thing; mastering more skills means having more ways to fight.

Most of the top experts in the past had their own weapons.

Rocks, Roger, Shiki, and the Four Emperors Whitebeard, Shanks, Kaido, and Charlotte Linlin all have their own weapons.

Aaron himself naturally had the regret of "having dreamed of traveling the world with a sword," but was powerless to do so.

In this world, however, it can be made up for.

But why would Bogart teach him swordsmanship?

Bogart seemed to see Aaron's doubts: "You were able to learn Tempest Kick in such a short time, so you should be able to easily perform Vacuum Slash or Flying Slash with a sword. Also, I've observed your hands; there are obvious calluses on the web of your right hand from using swords. And your physique—your coordination is excellent, and your arm span is longer than average. If you were to use a sword, you could become a great swordsman."

Aaron hesitated slightly: "But there are only six days left now. Besides, I need to learn Haki from Vice Admiral Garp, so I'm afraid I don't have much time."

Karp laughed heartily: "Aaron, you little rascal, Bogart has never offered to teach anyone swordsmanship! Do you expect him to beg you before you'll learn?"

"Of course not."

Aaron was fairly confident in Bogart's swordsmanship.

Although he rarely takes action, the only time he did so was when he used a knife to instantly slice Koby's pistol into a dozen or so even pieces back in Shields Town in the East Sea.

Garp has been chasing the Roger Pirates for decades, so it's impossible for him to fight the entire Roger Pirates alone. Rayleigh, Jabba, and the others must also be dealt with.

In the God Valley battle more than 30 years ago, according to the manga's matchup, Bogart's opponent should have been Rayleigh.

Seeing that Aaron was still hesitating, Bogart simply said, "Hey, you don't really want me to beg you, do you?"

Aaron chuckled, "How could I dare? It's just that I don't have any swords on hand right now. Besides, regarding timing... Lieutenant General Garp, what do you think?"

Karp said casually, "That's easy. They'll set off on their mission in six days. As for you, I'll give you three more days to learn from Bogart."

Aaron said, "Then there's no problem. But, headquarters should have an armory, right? Can I pick out a knife?"

Bogart said, "As for the knife, that's easy, I'll go pick one out for you."

"Then, thank you for your hard work, Master."

Bogart's downturned lips began to curve upwards, and a hint of life returned to his wooden-like face.

"It's settled then. In six days, you'll start learning swordsmanship from me."

"Yes, Master!"

Bogart nodded in satisfaction and pulled his hat brim down again.

Karp said, "Alright. That's all for today. Go back and get some rest. Tomorrow's lessons will be even tougher."

The six of them left the training ground together and headed towards the dormitory area.

Gross, Peacock, and Lark all congratulated Aaron on becoming Bogart's disciple.

Bellumeber, however, was very jealous.

He and Coby were brought back to Marineford from the East Blue by Garp, and they trained together under Garp's guidance.

In his view, Coby was to inherit Garp's iron fist, while he himself used two scrapers as weapons, and his skills were all learned from Bogart.

Therefore, in his mind, he was undoubtedly Bogart's disciple, even though Bogart never verbally acknowledged it.

Now Aaron has taken his position and stolen the master he recognized. How could he not be angry, jealous, and hateful?

Aaron didn't think too much about it. He went back to his dorm, took a shower, and fell asleep immediately.

The peacock and the lark lived together. After taking a bath, the lark was playing with two clay figurines, making silly "chichi" laughs as he played.

"This is me, this is him..."

He chuckled foolishly for a while, then stared blankly for a while.

The peacock shook its head: "Silly girl, you've reached the age where you're in heat..."

"Huh? Sister Peacock, what did you just say?"

The lark snapped out of her daze and turned back to ask.

"It's nothing, I just meant it's time to go to sleep."

The lark turned her head and stared at the two clay figures in a daze: "Sister, you go to sleep first, I'll play a little longer. You can turn off the light."

Peacock shook his head helplessly, thinking to himself, "I hope he won't hurt Skylark's feelings."

Under the moonlight, the lark placed the two clay figures beside her pillow, covered her face, and drifted off to sleep with a sweet smile.

The next morning, Garp continued to reinforce the Six Powers. In the afternoon, he taught the training methods for Armament Haki.

Gross and Peacock have mastered the basics of Armament Haki.

Armament Haki refers to the advanced forms of guns and iron blocks; one is localized hardening, and the other is full-body hardening.

These two techniques, Finger Pistol and Iron Block, are respectively offensive and defensive.

Garp explained, "Armament Haki can be used for both offense and defense."

By concentrating all one's domineering aura into the fingers, one can make them harder than steel, capable of piercing through any surface with a single point, and indestructible. Once mastered to a certain level, this ability can even be applied to swords and even bullets.

As for the iron block, it requires distributing the Haki over a larger area, with the ultimate effect being localized hardening to defend against enemy attacks. This is called applying Haki to the blade.

When your Armament Haki reaches a certain level, you can release it externally or use it to envelop and attack the enemy's internal tissues, causing greater damage.

In the Flower Country of the West Blue, there is a style of martial arts called the Eight-Strike Fist, which uses Armament Haki to penetrate the enemy's armor and body surface, causing damage to their internal organs.

Furthermore, in Wano Country, this usage is called "Ryuo" (流樱).

Karp then demonstrated the hardening of his fingers and body, and the hardened parts seemed to come alive, moving freely across his body surface, changing shape and size.

Garp patiently explained and demonstrated in detail the various uses of Armament Haki.

It took me two and a half days just to master Armament Haki.

On the fourth day, Garp taught him Observation Haki.

"I've heard that Coby has awakened Observation Haki, and Grus and Peacock are also able to use Observation Haki to predict the enemy's attack path."

However, in addition to predicting attacks, Observation Haki also has a higher-level use: foreseeing the future.

The fundamental principle is to use the five senses to perceive changes in the surrounding environment and the presence of living organisms, and to predict and avoid danger.

The highest level of Observation Haki allows one to hear the voices of all things.

Helmeppo exclaimed excitedly, "Mr. Garp, during the Marineford War, Coby could hear what others were saying. Would that be considered a high-level Observation Haki?"

Garp shook his head: "Still a long way off!"

Helmeppo tried to show off for Koby, but failed miserably and smacked his lips in frustration.

Karp said, "Listening to the voice of all things, hearing what people say, is only the most basic level. A higher level is being able to hear the thoughts in their minds, including not only humans but also animals!"

Even more amazing uses include transmitting one's consciousness to others, reading others' memories, and even telepathy capable of covering an entire island!
