Following Bogart to the deck, Yoriichi was still somewhat dazed.
He hadn't expected to start learning Haki so soon. He'd spent nearly a month at Marine Headquarters, and hadn't even seen the Six Powers or Haki, let alone learned them.
Zephyr had been kind to him, but in terms of combat skills, Zephyr had always adhered to Kong's orders, not teaching Yoriichi much.
Kong's reason for this was probably that he still had reservations about Yoriichi's background, intending to first cultivate Yoriichi's sense of belonging to the Marines, observe his character, and only after confirming his loyalty would he teach him relevant combat skills.
However, Garp wasn't the kind of person to be timid and hesitant, and the Fleet Admiral's orders were barely more important to him than a fart.
Seeing that Yoriichi had already mastered the Six Powers so quickly and could already apply some of the techniques in battle, he immediately decided to have Bogart teach Yoriichi Haki.
Garp didn't care about Yoriichi's background at all, nor was he afraid of forcing him to
learn too much. Since Yoriichi could learn it, he might as well learn as much as possible.
At this time, the warship had officially set sail. There were only a few marines scattered around the railings on the deck, observing the sea. The area was large and spacious.
On the lookout tower, Aokiji also found Garp. After greeting Garp, he silently stood behind Garp, looking down at Yoriichi and Bogard on the deck.
"Hehe, you're here."
"How's it going, kid?"
Garp noticed Aokiji's arrival, crossed his arms, and looked at Yoriichi on the deck. He suddenly asked with a smile.
"Very impressive. I've never seen anyone like this before, if he really hasn't been exposed to the Six Powers of the Navy before."
"To be able to master these skills in such a short time, this kind of talent is absolutely rare in the world."
Aokiji touched his hat and gave his evaluation. Upon hearing this, Garp's smile widened, and he muttered to himself,
"This kid has a long way to go."
"Yoriichi, the ability I'm going to teach you is called Haki."
"Simply put, Haki is an innate ability hidden within the human body."
"Observation Haki allows you to sense an enemy's strong aura and predict their movements; Armament Haki enhances attack and defense, and can also attack Logia-type Devil Fruits; and there's Conqueror's Haki, derived from spirit, killing intent, and willpower."
"Depending on its function, Haki can be broadly divided into these three categories."
"Observation Haki and Armament Haki can be awakened through training, but Conqueror's Haki is innate; perhaps only one in a million will awaken it by chance."
Saying this, Bogart gave Yoriichi a deep look before continuing,
"You'll begin by learning Observation Haki."
As Bogart spoke, he reached into his suit pocket and pulled a black cloth, tossing it to Yoriichi.
Yoriichi reached out and caught the cloth.
"Use this to blindfold yourself."
"Observation Haki, simply put, is the power gained after activating the potential of the five human senses."
"Smell, sound, airflow, even the terrifying will to instantly perceive an opponent's thoughts—these are all manifestations of Observation Haki."
"Simply put, it's perception, the perception of everything around you."
"Humans are beings who rely on their five senses to obtain information about their surroundings, with sight accounting for 90%."
"Blindfold yourself. If you can still accurately perceive your surroundings, then your Observation Haki has reached a basic level."
"I've heard that some strong individuals can use Observation Haki to foresee the future several seconds into the future during battle. If you reach that level, your Observation Haki has achieved a certain level of mastery." As Bogart spoke, he removed the sword from his waist and set it aside, then picked up a bamboo sword and stood in front of Yoriichi.
Without needing further explanation, Yoriichi obediently placed his long sword aside and replaced it with a bamboo sword. Under Bogart's gaze, he blindfolded himself with a black cloth.
"This kind of training... I've done it before."
"Will it really unlock my Observation Haki?"
Yoriichi wondered to himself as he did this training. He had practiced similar training in the Demon Slayer world before, but it hadn't been very helpful.
The reason was simple: he was born with a level of perception that allowed him to see clearly, and his senses were terrifyingly strong from a young age!
In battle, he didn't actually rely that much on his vision.
However, since Bogart had said so, Yoriichi didn't mind trying his training method. After all, the world was different, and perhaps the same training would have different effects.
"I'm about to attack you, so concentrate."
"Feel my aura, dodge my attack!"
Bogart explained everything to Yoriichi in great detail, unaware that Yoriichi actually had some understanding of Haki. However, Yoriichi listened intently, afraid that some things might differ from his own knowledge.
Hearing Bogart prepare to begin training, Yoriichi nodded, indicating he was ready.
"Whoosh whoosh whoosh!!!"
Seeing Yoriichi nod, Bogart, without further ado, forcefully swung his bamboo sword at Yoriichi's shoulder. This was merely a test; as the bamboo sword slashed, a clear whistling sound filled the air.
"Clang!"
A soft sound rang out as the bamboo swords clashed. Yoriichi simply parried Bogart's attack with a horizontal stroke of his bamboo sword.
"Huh?!" Seeing his attack blocked, Bogart was slightly taken aback. He drew his sword and then swiftly thrust it out again, this time targeting Yoriichi's abdomen. The thrust was completely different from the previous one; it was silent, making no sound whatsoever.
"Thud!" Bogart expected Yoriichi to take the full force of his attack, but to his surprise, Yoriichi, who had been blocking his attack with his sword just a moment ago, quickly sheathed it and delivered a precise vertical sweep, deflecting Bogart's attack.
Having his attacks blocked twice in a row, Bogart's face was filled with astonishment. He involuntarily stopped attacking, turning his head to look at the watchtower, his eyes filled with surprise and confusion.
Garp, on the watchtower, also took in the scene unfolding on the deck, his eyelids slightly twitching, seemingly also somewhat surprised.
"He seems to have studied Observation Haki before; I had a vague feeling about it when I fought him before."
"This kid seems to be able to predict my attacks."
Aokiji, who had also witnessed everything that happened on the deck, noticed Garp's surprise and said.
"..." Garp didn't speak, but his body unconsciously moved closer to the window, his hands resting on the windowsill, as if trying to see what was happening on the deck more clearly.
On the deck, Yoriichi, seeing that Bogart hadn't attacked yet, couldn't help but ask:
"Lieutenant Colonel, why aren't you attacking? What are you doing looking at the watchtower?"
Upon hearing this, Bogart turned his head and saw Yoriichi speaking with his eyes covered, speechless for a moment.
"Are your eyes covered with a black cloth?" As he spoke, Bogart reached out and waved his hand in front of Yoriichi's eyes. Despite being covered by a black cloth, Yoriichi's head followed Bogart's hand, and he replied,
"Yeah, it's blocked, I can't see anything."
Bogart was taken aback, thinking to himself, "This kid, is he cheating?!"
