"Fake."
Kyoya gave Tatsuki no room for imagination at all, stating directly: "Didn't you just come down from above with me?"
"This sky, these white clouds, they're all fake."
"It's a barrier set by that wooden sandal and hat guy just now."
"In terms of strength, it's somewhat inferior to the sky dome of Las Noches."
"Hueco Mundo? Sky dome?"
Hearing these things she hadn't known about before, a curious expression appeared on Tatsuki's face.
"Mhm, Orihime went with me to Hueco Mundo some time ago. You can ask her when she comes tomorrow."
"Of course, if you're really curious, once your training bears fruit, I can also take you for a trip around Hueco Mundo."
"Great, then I'll trouble you then, Master."
If it were someone else, they might act coy or reserved.
But not Tatsuki.
In her mind, if Orihime could go to Hueco Mundo with her Master for two weeks, then it was perfectly normal for her to go with her Master for a few days too.
"By the way, Master, what are you going to teach me?"
"What I'm going to teach you is a martial art called [Fish-Man Karate]!"
In the world of One Piece, the means of combat people use include Devil Fruit abilities, Haki, swordsmanship, and martial arts!
The strength of martial arts masters is in no way inferior to that of swordsmanship masters.
However, Kyoya hadn't been able to draw Garp's martial arts from the One Piece Achievement System.
But, he did have martial arts more suitable for Tatsuki.
Tatsuki herself had trained in karate since childhood. The most suitable thing Kyoya possessed for Tatsuki was naturally the Fish-Man Karate from Jinbei, the Shichibukai from Fish-Man Island.
"Fish-Man... Karate?"
"Is it karate created by fish-men?"
Hearing this, Tatsuki's furrowed brow relaxed slightly.
If it were other things, Tatsuki might feel she couldn't learn them.
But when it came to karate, she was very confident.
"Master, do 'fish-men' really exist in this world?"
If it were before, Tatsuki might have denied the existence of fish-men.
But now, having awakened spiritual pressure and seen certain things, especially after being brought by Kyoya to this place that didn't seem to exist in the real world, she felt that whether fish-men or mermaids, their existence was possible.
"In other worlds, there are definitely fish-men. But whether they exist in this world depends on whether there are Hollows with that form in Hueco Mundo."
Kyoya didn't outright deny Tatsuki's question.
Undoubtedly, the 'fish-man' race did not exist in this world.
However, the evolution of Hollows was bizarre and varied.
Especially the small and medium-sized Hollows that hadn't evolved to the Gillian level, and the Gillian that had gained self-awareness and begun evolving to a higher level… their bodies were like a hodgepodge.
Not to mention fish-men, Kyoya wouldn't be surprised even if there were Hollows with mermaid appearances.
"Alright, Tatsuki, let's begin!"
"Fish-Man Karate, its essence is a technique that attacks by controlling the surrounding water."
"Therefore, the first step in learning Fish-Man Karate is to 'perceive water'!"
"Perceive water?"
Tatsuki was dumbfounded.
She was a karate expert.
But she had never heard of needing to perceive water before practicing karate.
"That's right."
"Watch."
To help Tatsuki understand Fish-Man Karate better, Kyoya extended his hand. Then, under Tatsuki's astonished gaze, the moisture in the air condensed into a single water droplet, hovering in the palm of Kyoya's hand.
"This is [Water Gun]!"
Boom!
Kyoya thrust his palm forward. The water droplet instantly pierced through the rock ahead.
"This is 'Vagabond Drill'!"
Boom!
As Kyoya threw a punch, Tatsuki beside him felt herself being pushed away by a tremendous force.
The next moment, Tatsuki's hand was caught by Kyoya, who pulled her back to his side.
"See?"
"So-called [Fish-Man Karate] is the technique of controlling water and using karate to project the water outwards."
"The more water you can control, the stronger the power you can unleash."
Watching the power of Fish-Man Karate displayed by Kyoya, stars sparkled in Tatsuki's eyes.
She grabbed Kyoya's hand and exclaimed loudly: "Master, I want to learn this! Teach me quickly!"
"Alright, alright, alright. Since I've accepted you as my disciple, I naturally intend to teach you."
"Mhm mhm mhm."
"Urahara, please help create a lake here. For Tatsuki to train by the lakeside, her perception of moisture will be stronger, which can increase her training speed."
"Sure, no problem!"
Kisuke nodded.
The techniques Kyoya used just now were something he had never seen before.
Using a human body to perceive and control moisture, condensing it and striking it out.
Such ability was already not weaker than some Zanpakuto abilities.
If humans could master such an ability, then the small and medium-sized Hollows in the Living World could be easily eliminated by humans themselves, without Shinigami needing to intervene.
However, Kisuke still didn't know whether Hollows killed by this ability would be obliterated like those killed by Quincies, or if their souls would enter the Soul Society like those killed by Shinigami.
"Hado #57, Daichi Ten'yo!"
Boom boom boom-
As Kisuke half-squatted and slapped the ground, the floor of the underground training ground violently shattered. Rocks and soil flew out, destroyed by powerful Reiatsu, turning into a large pit dozens of meters in diameter.
Splash splash splash-
Kisuke's move directly breached an underground river, causing the river water to gush out and quickly fill the large pit, creating a small lake within the underground training ground.
Kyoya took a few steps forward, came to the edge of the lake, and extended his hand towards the lake-
"Hado #31, Shakkaho!"
Powerful Reiatsu condensed into a red fireball in Kyoya's palm, which he then launched.
Boom!
The fireball fell into the lake, causing a violent explosion. The intense heat evaporated a large portion of the lake water, creating thick mist all around the lake.
"That should do it."
Seeing this, Kyoya nodded slightly.
Since the goal was to perceive the moisture in the surrounding air, naturally the more moisture there was around, the faster Tatsuki could perceive it.
"Tatsuki, come over, it's time to start training."
"Yes, Master."
…
"Fish-Man Karate, Water Gun!"
In the underground training ground, Tatsuki thrust her palm forward. Moisture condensed into water droplets shot out like bullets.
In front of her, Chad's expression turned serious. He activated his Fullbring, causing his right hand to instantly transform into the black-and-red patterned Right Arm of the Giant.
Boom!
Chad threw a punch, shattering the water droplets Tatsuki launched.
On the other side, Tatsuki didn't stop moving, circling around Chad while carefully concentrating to perceive the moisture around her, gathering it into her hands with her spiritual pressure.
"Fish-Man Karate, Water Shot!"
Water Shot was the upgraded version of Water Gun.
If Water Gun was a bullet, then Water Shot was a cannonball ten times more powerful!
Boom!
This stream of water shot out from Tatsuki's hand, creating faint ripples in the surrounding air.
Seeing this, Kisuke narrowed his eyes.
He could confirm that Tatsuki right now was not in a Gigai state, but in a human body composed of Material Particles.
Yet, she could unleash attacks of this intensity, which is truly astonishing.
Keep in mind, from the time Tatsuki started training with Kyoya until now, it had only been two weeks.
Two weeks ago, Tatsuki was just an ordinary person, and her attacks couldn't even break the skin of a small Hollow.
But two weeks later now, Tatsuki's casually launched [Water Gun], if it hit a vital spot, could kill a small Hollow without problem.
Her current [Water Shot] could directly pierce through even a medium-sized Hollow.
Such progress was undeniably fast.
Even Chad now had to take Tatsuki's attack seriously.
Chad's expression turned solemn. Reiatsu erupted, and under its surge, his Fullbring condensed a black-and-red shield on his right shoulder.
Boom!
Tatsuki's Water Shot slammed into the shield on Chad's right hand, exploding with force and shaking Chad a few times.
"Tatsuki-san, so strong!"
Although Chad's face showed no expression, in his heart, he was astonished by Tatsuki's strength.
Fighting alongside Ichigo, Chad had encountered quite a few strong opponents.
During the Seireitei battle, Chad faced Kyoraku. Although he was instantly defeated, the feeling of powerlessness greatly stimulated him, leading to an evolution of his ability.
Perhaps wanting to withstand enemy attacks better in the next battle, Chad's ability gained the shield.
The strength of this shield was such that even a Gillian-class Menos couldn't break it.
The last one to break Chad's shield was the Diez Espada, Yammy.
Boom-
After stabilizing himself, Chad threw another punch. Powerful Reiatsu transformed into a shockwave, rushing towards Tatsuki.
"Shark Skin Sole!"
Boom!
Instantly, Tatsuki's speed surged drastically, allowing her to evade Chad's attack.
Shark Skin Sole was a technique in Fish-Man Karate for rapid advancement, similar in effect to the Marine's Soru or the Shinigami's Shunpo.
Training this technique to a high level allowed one to walk in the air like Moon Walk.
After using this move, Tatsuki's movement speed exceeded Chad's visual tracking ability.
Fortunately, Chad was no novice either. Having experienced numerous battles, Chad was also an elite who could adapt to Reikaku combat.
Boom!
Another punch. This time, Chad predicted Tatsuki's landing point. The powerful shockwave transformed into a white beam of light, rushing towards Tatsuki.
Fighting Tatsuki, Chad wasn't worried about injuring her.
He had a strong awareness of his own strength.
All around, Ichigo, Kyoya, and Urahara were watching. If Tatsuki was in danger, with their abilities, they could completely block his attack before she got hurt.
Even if they didn't intervene, with Orihime present, as long as Tatsuki still had a breath left, she could be fully healed.
While running earlier, Tatsuki had been continuously controlling and gathering the surrounding moisture. Now, facing Chad's attack, she immediately projected the moisture she had gathered using the secret art of karate!
"Fish-Man Karate, Vagabond Drill!"
Boom!
The white shockwave collided with the blue water ball, erupting in a huge roar.
Both Tatsuki and Chad were pushed back by the aftershock of the collision.
Chad's spiritual pressure was much stronger after all, and his physical strength was far beyond Tatsuki's. He only retreated two or three steps.
Tatsuki fared worse, being blown back and only stabilizing herself after retreating seven or eight meters.
"Alright, that's enough!"
Seeing Tatsuki start to pant, Kyoya made a stopping gesture, halting their spar.
"Huff..."
Tatsuki let out a light sigh and wiped the sweat from her forehead.
"Wow, Tatsuki was so cool just now!"
Orihime came to Tatsuki's side, her big eyes fixed on Tatsuki like a little fan.
"Not at all, I'm still far behind compared to Sado."
Although the fight with Chad just now seemed intense, Tatsuki knew that during their battle, Chad had held back a lot.
The only attack of hers that posed a threat to Chad was the Fish-Man Karate's Secret Art, Vagabond Drill.
But for her current self, this move wasn't easy to execute.
Just the moisture required for Vagabond Drill took her a long time to gather.
"We're different."
Chad's right hand returned to its normal arm shape. In his deep voice, he said, "As Kyoya-sama put it, Orihime and I are lucky, possessing certain special traits, which is why we have our current power."
"But Tatsuki, you're different."
"You truly trained your power yourself."
"That's right."
Kyoya nodded. "Tatsuki, Sado and Inoue had their own opportunities, but you have your own hard work."
"Fish-Man Karate is related to the amount of moisture you can control."
"Right now, you can only instantly condense water droplets. When you train to the point where you can condense water balls at will, your Water Gun will possess the power of your current Vagabond Drill."
"By then, your Vagabond Drill could even kill a Menos."
"And that's just you gathering moisture from your surroundings."
"Have you ever thought, what if you didn't need to gather moisture, but directly used water?"
"If you carried a bottle of water with you and used the water inside during battle, you could easily unleash Vagabond Drill, which currently requires you to gather moisture for a period of time."
