"What did you say?!"
Gong Denghua suspected there was something wrong with her hearing.
Kai looked at Gong Denghua with a smile and said, "I said I have learned it."
"Impossible! Absolutely impossible!"
"Observation Haki is different from Armament Haki. It not only requires hard work to learn, but the most important thing is..."
Gong Denghua was a bit excited. Observation Haki was indeed different from Armament Haki; it was much more difficult to master.
Talent played a significant role in its mastery, and very few people in the Nine Snakes crew had successfully learned Observation Haki.
Even her sister Marigold had only a limited proficiency in it.
"Don't get too excited. I said I learned it, but I didn't say I mastered Observation Haki. I just developed a method similar to it."
"What do you mean?"
"I still don't fully understand what Observation Haki is, but I can enhance my five senses to an ultimate level, achieving effects similar to Observation Haki."
"..."
Everyone in the Nine Snakes crew was speechless. Wasn't this essentially Observation Haki?
"Brother Kai, we've learned it too."
Both Shisui and Itachi had practiced the breathing techniques to a high level of vigilance and had mastered their own bodies to an ultimate degree. Their talents were only slightly inferior to Kai's.
"Well, yes, Observation Haki is a valuable ability, but for us, it serves more as a support role; our eyes are the most important."
While Observation Haki was useful, it paled in comparison to the Sharingan.
His was the Mangekyō Sharingan. To possess such precise and powerful vision and to pursue the vague perception of Observation Haki would be to neglect the fundamentals.
"We all understand that."
Shisui and Itachi had just enhanced their five senses like Kai, but their senses felt significantly inferior to when they used the Sharingan, leaving them with a sense of discomfort.
However, Observation Haki had its advantages, especially in the world of Naruto, where it could easily detect ambushed enemies, making it more useful than the Byakugan in certain situations.
Without the Sharingan, they would take the practice of Observation Haki seriously, but the power of the Sharingan far surpassed that of Observation Haki.
With the Sharingan, Observation Haki could only serve as a supplementary skill.
Then Kai and the other two began various attempts.
The Nine Snakes crew stopped talking and quietly observed Kai and the others. For the first time, they felt the weight of a dimensionality reduction strike.
Was hard work truly worthless in the face of talent?
After an unknown amount of time, Hancock opened her eyes and clearly felt that her physical fitness had improved significantly.
As she returned to normal breathing, her physical condition began to stabilize, leaving her with a sudden emptiness in her heart.
In the past, she would never have imagined that simply breathing differently could make such a huge difference in her physical abilities.
At the same time, she realized that this breathing method required strong lung capacity. To fully replace ordinary breathing with this technique, one had to strengthen their lungs.
At that moment, she deeply appreciated the importance of this breathing method. If all members of Amazon Lily practiced it, their strength would see a tremendous boost.
That annoying guy is quite generous; maybe he likes me.
No, he definitely likes me. I am the 'most beautiful woman in the world,' after all. Who wouldn't be attracted to me?
"I wonder how that guy is doing with Observation Haki. It's not easy to learn."
As Hancock thought of Kai, she felt an urge to see what he was up to.
If he hadn't learned it, she wouldn't mind coaching that annoying guy.
Boom!
A sound like a cannon shell exploding startled Hancock. She thought the ship was under attack and immediately rushed out of the cabin.
"What happened?! Who's attacking?"
"No, no, sister Hancock, look over there."
Hancock followed Marigold's pointing finger, and her pupils widened in shock.
Kai, Shisui, and Itachi were standing on the sea, facing each other in a triangle formation.
"This is?!"
How is it possible for someone to stand on the sea without sinking? How can this be?
"What are they doing?"
Gong Denghua explained, "They have been studying and researching Haki, and now they want to see its effects in actual combat, which is how this scene came to be."
Uchiha Shisui smiled and said, "Brother Kai, we need to take this seriously. Don't be upset if we lose."
"You're the one who should be careful. Just don't cry when you lose. I still remember how you looked when you cried."
Uchiha Shisui couldn't help but get angry at Kai's words. "Those were just things that happened when I was young! Let's do this! Itachi!"
Boom!
Three spiral currents suddenly erupted on the calm sea around Kai, all aiming directly at him.
Kai seemed to have anticipated this and smiled as he said, "I knew you would do this, Itachi."
"Water Style: Water Barrier!"
Kai muttered lightly, and the seawater around him quickly rose to form a barrier, successfully blocking Itachi's water fang bullets.
"Fire Style: Great Fireball Technique!"
Uchiha Shisui quickly formed a series of seals and unleashed a massive burning Great Fireball, over three meters in diameter, from his mouth.
"This kind of attack is useless against me."
Kai raised his right palm and then slashed through the air toward the Great Fireball.
His slash cut through the fireball, splitting it in half mid-air.
Boom! Boom!
The two halves of the fireball fell onto the sea, creating a powerful steam explosion.
"Haki released!!"
The women of the Nine Snakes exclaimed. Although they had seen Kai use Haki on the ship before, how could he use it so skillfully and quickly? Moreover, the distance of the external release seemed to be incredibly far.
