The two fought, but it certainly didn't happen at the Wisteria House.
In the original work, the Sound Hashira, together with Tanjiro and others, fought against Upper Rank Six and tore apart a section of Entertainment District courtyard. They went all out in the courtyard and would have destroyed it in just a few moves.
The location chosen by Uzui Tengen was a secluded wilderness outside the city.
Even if you're exhausted from fighting, as long as you get back before dark, you don't have to worry about ghosts taking advantage of you.
As for the injury...
Uzui Tengen didn't think he would get hurt, and was confident that with his control over his wrist strength, he wouldn't be able to injure Uchiha Meikyō.
He even demanded that Meikyō go all out.
However, after only a few moves, he completely changed his mind.
We're both ninjas, so why are your Ninjutsu and Ninjutsu completely different?
Uzui Tengen's Fire Style cleverly utilizes the explosion of a bomb containing gunpowder to force back and shock the opponent, and uses smoke to confuse the enemy.
Uchiha Meikyō's Fire Style -
"Fire Style: Great Dragon Fire Technique!"
A dragon-shaped flame roared across the Uzui Tengen and exploded on the ground.
After quickly dodging Meikyō's Fire Style attack, Uzui Tengen no longer has any intention of taking on a successor.
The opponent's strength is already comparable to that of a Pillar of the same level!
"Although your Ninjutsu is very flashy, if I were to be defeated by a newcomer like you, it wouldn't be flashy at all for me!"
Uzui Tengen couldn't help but complain, then continued the battle with greater composure, focusing on defense while constantly familiarizing himself with the battle rhythm of the Meikyō.
"Sound Breathing - First Form - Boom!"
Taking advantage of his height, Uzui Tengen swung his Black-Gold Nichirin Blade downwards, accompanied by a deafening explosion as the two blades collided.
With his height of 1.98 meters, this move was indeed a perfect fit.
Meikyō stepped back, not taking the powerful blow head-on. Then, she flipped her wakizashi and swiftly drew a fiery semicircle from bottom to top.
"Uchiha Style: Instant Fire Blade!"
Although Meikyō can now use Breathing Technique and Chakra to refine Senjutsu Chakra, he is not yet proficient in Flame Breathing, and the refining process still has a certain amount of pre-cast delay.
Uzui Tengen was born a ninja, and his footwork and swordsmanship were exceptionally fast. It wouldn't be easy for him to find an opportunity, so it would be better to use his most proficient fighting style.
After a series of exchanges, Meikyō even gained the upper hand in the battle by relying on the special nature of Ninjutsu.
However, Uzui Tengen had seen all sorts of strange and bizarre Blood Demon Art when he fought demons before, so he dealt with them quite well and even became more and more excited as the fight went on.
Because only now is he at his strongest.
Because his Musical Score is finished!
That was a unique combat calculation formula mastered by Tengen Uzui, which calculated combat data such as the enemy's moves. Although it took a certain amount of time to complete the analysis, it was possible to understand the rhythm of the enemy's attack movements by studying and judging them, converting them into musical notes, thereby understanding the opponent's attack habits and blind spots.
It's a bit troublesome, but it allows him to see through all the enemy's attacks and find the optimal opportunity.
"Now that the shop is finished, it's time for me to claim victory in style!"
Uzui Tengen swiftly swung his twin swords, deflecting Meikyō's blades and launching a continuous barrage of attacks. At the same time, as if he had a premonition, he dodged every single one of Meikyō's attacks.
"Three, seven, five, six, four, for, towel... Your attacks, all of them, I've brilliantly seen through!"
Numbers one through ten, plus "dou", "wei", and "jin", represent thirteen different timbres for the zither.
For Uzui Tengen, this battle had become a rhythm game.
"It is indeed very flashy, but I have even more flashy abilities! Your movements have already been seen through by my eyes!"
A touch of crimson appeared silently in Uchiha Meikyō's eyes.
With his Three-Tomoe Sharingan eyes constantly moving, his powerful perception and dynamic vision allowed him to see through every attack from Uzui Tengen!
Blades clashed, the sound of metal clanging echoed continuously, and explosions caused by gunpowder and Ninjutsu resounded throughout the wilderness.
"Are you... are you kidding me?! Is this... this is the strength of a Pillar?!"
Not far from the wilderness where the two were fighting, on a small hillside, two hidden figures who had followed them out out of concern stared in disbelief at the intense battle between the two below.
"No, that's not all! I never expected that guy named Gunbai something to be so powerful, actually fighting on par with Lord Sound Hashira!"
"Are they evenly matched?"
At the Demon Slayer Corps Headquarters, Ubuyashiki Kagaya was surprised to hear Uzui Tengen's words, but then he was delighted.
"In fact, although they are evenly matched, I feel that Uchiha Meikyō still has some strength left. At least he has other methods that he has not used. If it were a life-or-death battle, I would definitely be the one who dies. As for all the Pillars, I think that except for Himejima, the other Pillars would probably have the same result, because his special Ninjutsu is definitely more troublesome than the Blood Demon Art of the Demon King!"
"Uzui Tengen said with a solemn expression."
To deal with Meikyō, he even brought out his most treasured Musical Score.
In fact, Meikyō did have Genjutsu techniques that he hadn't used yet.
"Is it really that strong?" Ubuyashiki Kagaya looked astonished, then a peaceful smile appeared on his face. He had not yet been disfigured by his ancestral illness, but a patch on his forehead had turned purple.
"It's wonderful that such an outstanding person is willing to join us."
"Furthermore, since he has gained the approval of you, Uzui, and Kyōjurō, this child named Meikyō must also be trustworthy. In this way, as the Demon Slayer Corps continues to grow stronger, we will have a better chance of eliminating the Demon King."
Uzui Tengen nodded in agreement, then recalled Meikyō's technique, which was completely different from his own but significantly more powerful, along with the various Ninjutsu and skills used in its execution.
"I can confirm that he does indeed bear the marks of rigorous ninja training from a young age. He must have been trained by a highly sophisticated ninja organization, so his background should be fine. Moreover, he possesses Ninjutsu that is even more dazzling than mine. This must be a unique technique passed down by the Konoha Style ninja school, because it is completely different from the Ninjutsu of other ninja schools!"
"The scariest thing is that guy learns things very quickly."
Ubuyashiki Kagaya didn't understand the meaning of Uzui Tengen's last sentence, but he still stood there quietly and listened to Uzui Tengen finish speaking.
"After watching my demonstration just once, he learned all the moves of the five forms of Sound Breathing. After asking me about some of the secrets needed to cultivate Breathing Technique to a high level, he directly demonstrated the complete Sound Breathing set in front of me!"
