Kaoru's sudden appearance surprised everyone.
"It's okay if I join now, right?"
However, the response that emerged was just an amazed laughter from Madara.
"HAHAHA, amazing! With chakra like that, how could I not have noticed from the beginning? Kid, tell me how you hide your chakra. Even my eyes didn't detect anything. I only realized it after that attack!"
If it were an ordinary person, they would never reveal their powers to their enemies. However, Kaoru, knowing that his plan had succeeded and that, regardless of Madara's actions, he would be the winner in the end, didn't mind sharing his tricks.
"It's easy; I just use a camouflage cloak that can hide chakra or anything that allows someone to detect my presence! If you're interested, I don't mind selling it. I'll sell it for 10 billion ryo each, a bargain, right?"
"Look, this cloak has fire-resistant features and an automatic temperature regulator. Besides, the material is strong enough to withstand attacks from weapons as powerful as the Mist Village's seven-sword style!"
Kaoru then tirelessly promoted his product like an experienced salesperson until they forgot they were on a battlefield. Madara had to interrupt and bring them back to reality.
"I didn't expect such a thing in this era. But with the fact that the current Kage are just a bunch of trash, that means you are an anomaly. Your chakra always changes, sometimes like a genin, but sometimes reaching levels even beyond me and Hashirama!"
"Kid, let's dance! I want to see how strong you are!"
Madara, still using Susanoo, suddenly created a sword from chakra and soared towards Kaoru, mercilessly slashing him.
*BOOM
Although Madara's attack was a slash, its effect was like a bomb, and Kaoru, who directly received the attack, surprisingly suffered no injuries. He could even withstand Susanoo's slash from Madara with his own sword.
While Madara's Susanoo was much larger than Kaoru's sword, it didn't mean Kaoru's weapon was a cheap one that could be picked up on the roadside.
Kaoru's sword was named 'Song of Broken Pines' from the game Genshin Impact, but with some modifications and spending some extra guild points, Kaoru managed to obtain an elemental weapon.
Initially, Kaoru wanted to buy 'Musou no Isshin' owned by Raiden Shogun, but due to the divine factor used in making the weapon, its price became very high, even exceeding some abilities that Kaoru considered very strong. Therefore, Kaoru chose that claymore because he felt it was more suitable, and it was also much cheaper.
----
Madara, whose attack was successfully blocked by Kaoru, didn't feel surprised at all. Instead, he felt pleased because this time, he found a suitable opponent, even without Hashirama in the current era.
Seeing that Kaoru received no scratches, Madara launched another attack with his Susanoo, which Kaoru still easily parried.
On the other hand, Kaoru, who received the attack, also didn't want to lose and began launching counter-attacks.
Kaoru's ice-element-covered attacks and Madara's Susanoo attacks capable of crushing mountains clashed, creating destruction around them.
Initially, everyone could still observe their battle, but gradually, the pace of the battle became faster, reaching a point where even the Kage had difficulty keeping up.
All they could see were flashes of blue light that destroyed the surrounding area or froze it.
"I didn't expect that the kid is so strong. The Hokage seems to be very lucky to have a shinobi as strong as him. If only Iwa had talent like that." Oonoki lamented the fate of his village, lacking such excellent talent.
"Grrr!" Meanwhile, the Raikage could only growl, realizing that he wasn't strong enough to retaliate against Kaoru's actions on his village.
Tsunade, Mei, and Gaara could only stay silent because they also didn't expect Kaoru to be so powerful, especially Tsunade, who initially knew that Kaoru was strong but didn't think he had reached the same level as Madara and her grandfather.
----
"Hahahaha, amazing, this is what I've been looking for. Keep dancing, kid!" Madara continued to attack and defend while laughing maniacally.
Meanwhile, Kaoru just smiled without saying a word. At this point, he was only waiting for Naruto and the other Jinchuriki to arrive to become sacrifices for the Gedo Mazo.
Moreover, with the effect of his sword, Kaoru gradually froze Madara's Susanoo. Madara, realizing this, wouldn't just stand by.
Madara, who now had one of his eyes, released an enormous amount of chakra. Along with that, his Susanoo also grew larger.
The significant change was also visible in the shape of his Susanoo, which had now reached a size of over 100 meters. It resembled a samurai with a Tengu mask and wings at the ends shaped like hands, each holding a sword.
"Kid, I'll show you the Uchiha Clan's greatest power!" Even though he was in the head part of Susanoo, Madara's voice could still be heard clearly, as if the Susanoo itself was speaking.
Madara then drew his Susanoo's sword and made a massive slash towards Kaoru.
Kaoru, realizing that the attack was dangerous, immediately avoided as far as possible, and of course, the location where Kaoru was previously split.
Not only that, the attack created a massive, deep, and long rift, effectively splitting the continent into two.
With Madara now taking the battle seriously, Kaoru had no choice but to fight seriously as well.
Kaoru created wings of ice and flew to avoid Madara destroying the entire continent.
After stealing and modifying ryumyaku chakra, Kaoru had reached the super-Kage level in terms of chakra quantity. Now he would showcase his power to Madara, who had shown off first.
Suddenly, a chakra with a beautiful sky-blue color burst out from Kaoru's body, and in an instant, the sky darkened, and snow began to fall, covering and transforming the battlefield from a desert into a cold snowy landscape.
With full control of the entire field, Kaoru created ice blocks with various sharp weapon shapes and threw them towards Madara.
Madara himself didn't stay idle; he destroyed all the attacks launched by Kaoru. However, with only four hands in his Susanoo, Madara couldn't block all the attacks directed at him.
Slowly, Madara was pushed back by Kaoru's barrage of attacks, and this time, Madara had to admit that Kaoru was very strong. Still, Madara was confident that defeating Kaoru would be easy once he became the Jinchuriki of the Ten-Tails.
While they were engrossed in their battle, a humanoid-shaped statue suddenly appeared, diverting their attention.
Seeing Gedo Mazo appear made Madara and Kaoru happy; it meant the war would be over soon.
Kaoru, not wanting to waste the opportunity, immediately tried to temporarily seal Madara.
"Ice Age!" With that command, a wave of chakra attacked from all directions. When it touched Madara's Susanoo, the Susanoo instantly turned into a giant ice statue.
Even though Susanoo was made of condensed chakra forming a giant armor, Kaoru's technique could freeze anything except entities or formless objects and beings that had reached the transcendence level.
Since Susanoo was chakra condensed and forming a giant armor, it could be frozen by Kaoru.
"It seems I went overboard, tehee!" Kaoru tried to find excuses after seeing the area around him filled with ice blocks.
"I knew it! Madara is indeed very strong. He even managed to escape and avoid that attack!" Realizing that the statue in front of him was just an empty shell, Kaoru headed towards where Gedo Mazo appeared.
Now he just had to wait for Madara to absorb the tailed beasts' chakra and become the Ten-Tails Jinchuriki and enter the Six Paths mode. At that point, it could be said that Kaoru's plan would be 100% successful, and they could return to their respective worlds.
