Bogart was somewhat incredulous that Yoriichi had even mastered Observation Haki. He immediately demanded that Yoriichi remove the black cloth, put it on himself to test it, and after confirming he couldn't see, he went to Yoriichi's side and personally put the black cloth back on him.
"Try again."
"Get ready."
A strange competitive spirit rose within Bogart. After putting the black cloth back on Yoriichi, he raised his bamboo sword.
*Shave!*
In the blink of an eye, Bogart's figure had vanished from Yoriichi's sight. When he reappeared, he was already beside Yoriichi, his bamboo sword silently slashing towards Yoriichi's shoulder.
He didn't attack from behind, because Bogart knew that some strong individuals had exceptionally keen senses in both the front and back directions, and attacking from the side often caught them off guard.
"Thud!"
Yoriichi, who was facing forward, reacted the instant Bogart used Shave. His bamboo sword caught Bogart's attack perfectly, and Yoriichi even launched a counterattack, blocking the attack while kicking Bogart in the waist.
Not only did Yoriichi accurately catch the attack, but he also accurately pinpointed Bogart's position to launch a counterattack.
"Bang!" Bogart clearly didn't expect the blindfolded Yoriichi to be able to counterattack. Caught off guard, he was kicked in the waist and swayed several meters before stopping.
Yoriichi frowned slightly. That kick felt like he had kicked a thick iron plate. Bogart reacted quickly, using Iron Body the instant the attack arrived.
"As expected! This kid can sense it!"
Bogart was shocked. He was certain that Yoriichi could sense his movements. Unable to contain his astonishment, he asked,
"You've learned Observation Haki before?!"
Yoriichi shook his head and said, "I sensed your 'fighting spirit'."
In the Demon Slayer world, everyone possesses fighting spirit; the stronger the person, the stronger their fighting spirit. Yoriichi, having reached the Transparent World realm, could sense this fighting spirit. Only those who have reached the state of selflessness can eliminate this fighting spirit.
When Yoriichi killed Muzan, Muzan couldn't sense Yoriichi's fighting spirit, thinking he was just an ordinary person, uttering a line similar to the bandit king's: "Pillars, huh? I have no interest in people with this kind of strength." However,
only when Yoriichi made his move did Muzan realize how wrong he was.
Although the worlds are different, some things are the same. Humans all need to breathe, and the aura of the strong is far stronger than that of ordinary people.
Standing before Yoriichi, Bogart was like a star in the night sky, quite conspicuous on this warship. Even in Yoriichi's perception, the pair of "sun and moon" on the watchtower were very clear.
"You sensed fighting spirit?"
Although Bogart didn't know what Yoriichi specifically meant by "fighting spirit" he could tell from Yoriichi's words that Yoriichi could probably sense something, which was why he could avoid his attacks and track his movements.
Although he didn't know why, Bogart knew that this training was no longer necessary.
He didn't know if Yoriichi had mastered Observation Haki, but Bogart knew that since the other party had a way to track his movements, then this training had lost its meaning.
Now, Bogart was a little unsure what to do. Should he skip Observation Haki and teach Armament Haki? That was too fast. Bogart hadn't actually planned how to teach Yoriichi Armament Haki.
"Hahahaha!"
"You're really unexpected!"
"Bogart, let me handle this."
Just then, Garp's voice came from behind Bogart. Garp walked to Yoriichi's side, laughing, patted Yoriichi on the shoulder, and praised him.
Yoriichi took off his black cloth and smiled slyly when he saw Garp.
"Don't take it off, don't take it off."
"The training isn't over yet."
Garp patted Yoriichi on the shoulder and said with a big laugh. Hearing Garp's words, some bad memories flashed through Aokiji's mind, and his eyelids twitched involuntarily. He silently prayed for Yoriichi.
"Kid, next, I'll attack you. You'd better dodge well!"
As Garp spoke, his aura changed. In Yoriichi's perception, the "fighting spirit" on Garp's body suddenly disappeared.
"!!!" As Yoriichi was surprised, a strong gust of air rushed towards him.
The next second, Garp's fist slammed straight into Yoriichi's head, causing Yoriichi to stagger and almost fall to the ground.
"As expected, he didn't predict the opponent's attack using Observation Haki, but only judged it by the opponent's aura."
"A swordsman's instinct?!" Garp grinned, understanding dawning on his eyes. On this vast ocean, some swordsmen could determine an opponent's location and attack by sensing their killing intent and aura.
However, this was not the same as predicting an enemy's attack with Observation Haki. The ultimate Observation Haki could instantly cover an entire island, like Rayleigh, or predict an opponent's attack seconds in advance, like Katakuri.
The "sensory perception" that Yoriichi possessed was clearly different from Observation Haki.
"Hehehe, I think I know how you sensed your opponent's attack."
"But it's useless against me."
"If you don't master Observation Haki soon, you're in for a rough time!"
Garp grinned, and before he finished speaking, he was right in front of Yoriichi, throwing a punch at his chest. The whistling wind from the punch allowed Yoriichi to catch Garp's attack, his bamboo sword flashing to block it.
"Snap!" The bamboo sword broke in the next second, and Garp's fist slammed into Yoriichi's chest, sending him flying.
"Thump!"
Yoriichi flew several meters and crashed onto the deck, the loud noise drawing the curious gazes of the surrounding Marines.
Yoriichi quickly got to his feet. Although he had used his Iron Body technique when the attack landed, Garp's fist still caused him excruciating pain in his chest. He could feel the dull, burning sensation in his chest with every breath.
"Oh, right."
"While training Observation Haki, you should also train Armament Haki simultaneously."
"When Armament Haki fills your body, it increases your resilience."
"Now, use your senses to find traces of Armament Haki on me, learn it, and activate your own Haki."
"Then, take my punch!"
"If you don't master it quickly, you won't last long!"
Garp grinned, his fists clenched.
Although Yoriichi knew Garp had held back, the feeling of being punched was incredibly painful—a pain he hadn't experienced in a long time. If Garp had knocked him unconscious, it would have been easier; experiencing pain while fully conscious was unbearable.
"Truly a top-tier fighter on the high seas, he's reached the state of 'no self,' able to conceal his aura during attacks."
"In that case, I'll have to use other methods to dodge Vice Admiral Garp's attacks."
"Observation Haki and Armament Haki, huh?"
"I will master them!"
Yoriichi casually tossed aside his broken bamboo sword and rose to defend. In this kind of training, having a sword or not made no difference!
"Bang!"
"Thump!!"
"Hahahaha! brat!"
Garp's laughter and the sound of Yoriichi slamming his fist on the floor frequently echoed on the deck.
Garp enjoyed this feeling of beating up a child to cultivate the next generation, and he was all smiles while training Yoriichi. Aokiji, having watched for a while, couldn't bear it any longer. He shook his head, went to the cabin, and found the ship's doctor, asking him to prepare some medicine.
Bogart, after watching for a while, also silently went to the engine room, taking on the role of commander, allowing Garp to focus on "instructing" the young man.
Under the intimidating force of Garp's iron fist, by the afternoon, Yoriichi was finally able to dodge some of Garp's attacks. At the same time, he vaguely sensed the presence of Armament Haki.
Although the Haki was weak, it was still palpable, and Yoriichi tried to use it defensively.
As for attacking? Yoriichi could only take the hits blindfolded, temporarily lacking the ability to retaliate against Garp.
Garp clearly sensed the changes in Yoriichi, his smile becoming increasingly rough and radiant.
"Terrifying talent! Truly terrifying talent!"
"Hahahaha!"
