"A rare sight, the Captain-Commander's Bankai."
A long-lost battle intent appeared on Tenya's face, and he took out Zangetsu from the system space.
"Getsuga Jujisho!"
"Zanka no Tachi East - Kyokujitsujin!"
Concentrating all of Ryūjin Jakka's flame heat at the tip of the blade, it neither burns nor releases explosive flames, but simply eradicates anything it touches without a trace.
Yamamoto swung his sword forward, and the super-high temperature slash, close to the sun's core, erased the cross-shaped Getsuga.
Amenotejikara.
Tenya's Rinnegan locked onto a stone behind Yamamoto, performing spatial displacement.
"Zanka no Tachi West - Zanjitsu Gokui!"
Yamamoto knew he couldn't compete with Tenya in speed. He transformed his Reiatsu into flames of 15 million degrees, covering his body and blade as if wrapped in the scorching sun.
If one were to approach him without any defense, they would instantly turn to ash.
Tenya's Eternal Mangekyo Sharingan saw through the latter's movements and immediately summoned the Nine-Tails'Chakra.
Sizzle, sizzle, sizzle!
The golden Nine-Tails Chakra cloak blocked most of the high-temperature flames, emitting bursts of white steam. The terrifying super-high temperature forced Tenya to retreat as well.
"To be able to touch this old man who is wearing Zanjitsu Gokui, you are truly an incredible fellow."
Wherever Yamamoto stepped, it turned into scorching lava.
"To be recognized by the Captain-Commander, I am honored."
Tenya actively removed a part of the Nine-Tails Chakra cloak on his body that was entangled with flames.
"Zanka no Tachi South - Kaka Jūmanokushi Daisōjin!"
By inserting Zanka no Tachi's blade into the ground, the Zanpakuto's high temperature awakens the ashes of those who died by Yamamoto's sword in the past, transforming them into countless charred skeleton legions.
"Mere specters, dare to oppose me?"
Tenya stomped his foot on the ground, integrating Conqueror's Haki into the Tremor-Tremor Fruit ability. This caused a massive earthquake that affected the entire Seireitei.
Rumble!!!
Large areas of houses collapsed, and the ground cracked, shattering countless skeleton legions.
"This, this power.... Is it too exaggerated?"
The Shinigami present showed expressions of horror.
Rukia and Zaraki's fight was also forced to stop.
"Tsk. I really want to go up and take a couple of swings, but I guess I'd be the one to die, right?"
Zaraki found that his sword-holding hand was trembling, both fearful and excited.
Seeing the skeleton legions he summoned completely annihilated, Yamamoto had no choice but to personally enter the fray.
Boom!
A simple and unadorned slash.
"As expected, I can't resist with just Shikai?" Tenya's Zangetsu was roasted red-hot.
"Chaotic Reiatsu, mixed with the power of Shinigami, Hollows, and Quincy..."
"Tenya, who exactly are you?"
Yamamoto stared at Tenya with sharp eyes.
"Just an ordinary human."
Tenya stacked the two swords in his hands together.
"Bankai, Tensa Zangetsu!"
The two swords merged into one, revealing a Zanpakuto that was black on the inside and white on the outside, without a tsuba, with a chain connecting the back and the end of the blade.
Black and white patterns appeared on Tenya's body surface, and half of a Hollow mask appeared on his forehead.
This was the true Tensa Zangetsu!
The ultimate chaotic form that combined Shinigami, Hollow, and Quincy.
Boom!
It was also a simple and unadorned slash.
Yamamoto was sent flying back, blood splattering from his body. If it weren't for the layer of Zanjitsu Gokui covering his body, which offset a portion of the damage, Tenya's slash would have been enough to cut him in half.
"Old Man Yama!"
"Captain-Commander!!"
Everyone couldn't help but gasp when they saw this.
Yamamoto, in his strongest Bankai state, was injured.
"Don't come over!"
"This old man isn't dead yet!"
Yamamoto stopped everyone from helping.
"Ukitake, can your Sōgyo no Kotowari absorb and reflect that slash?" Shunsui said in a deep voice.
"No, I can't do it..."
"Shinigami battles are battles of Reiatsu, and the difference in power is too great." Ukitake smiled bitterly and shook his head.
His Zanpakuto, Sōgyo no Kotowari, could absorb the enemy's physical attacks and then convert 100% of them to strike back. But the premise was that his Sōgyo no Kotowari could withstand the opponent's Reiatsu attack, otherwise, let alone striking back, his Zanpakuto would be ruptured.
"It's truly shameful, in a battle of this level, there is absolutely no room for us to intervene." Sajin shook his head helplessly.
"As expected of my man, his power has become much stronger than before." Unohana smiled and murmured to herself.
"Eh? Captain Unohana, what are you saying?" Soi Fon, who was beside her, looked confused.
Boom!
The battle between Tenya and Yamamoto was earth-shattering.
Fortunately, there were other Captains of the Gotei 13 present, who jointly cast Kidō defensive barriers. Otherwise, the residual shockwaves from the two fighting would have been enough to level the entire Seireitei.
"To be able to fight old man Yama using Bankai to a standstill, this boy is simply a monster." Shunsui exclaimed in amazement.
"Captain-Commander..."
"His stamina is giving out."
As the Captain of the medical squad, Unohana could instantly assess Yamamoto's physical condition. Yamamoto was over a thousand years old. Although Shinigami have long lifespans, this was already reaching the limit of a soul. His stamina and various aspects had declined.
As the high-intensity battle continued, Yamamoto gradually became breathless, and his Reiatsu dropped sharply.
Conversely, on the other side, although Tenya also had many injuries, he possessed astonishing recovery ability, and his Reiatsu was quite abundant, showing no signs of weakening at all.
"The sparring ends here. I don't want to bully an old man."
After repelling Yamamoto with a single strike, Tenya stopped further attacks.
"Huff huff huff..."
"This old man still has the strength to fight."
Yamamoto was incredibly stubborn. Even though he was exhausted, he refused to admit defeat.
"Wait a minute..."
"Old man, if you keep fighting, our barrier won't hold up."
Ukitake's eyes rolled. Familiar with the latter's temperament, he knew how to persuade the other party.
"What?"
"You younglings, can't even handle maintaining the field?"
Yamamoto glared at everyone angrily. Having no other choice, he reluctantly released his Bankai.
"Captain-Commander, actually, we can still..."
Sajin was an honest person, no, he should be called an honest dog. Although his strength wasn't great, his Reiatsu was quite thick, and the Kidō barrier could hold on for a while longer.
"Shut up! Can't you read the room?" Soi Fon snapped at him from the side.
She thought, if these two continued fighting, the entire Seireitei would turn into ruins.
"Um, Tenya. We could say we've become friends through fighting. How about coming over for a drink?" Shunsui extended an invitation with a friendly expression.
This was the respect brought by strength. What intruder, what rules, all could be ignored.
"Hmph!"
Seeing this, Yamamoto only let out a heavy cold snort, then flicked his sleeve and left. His skills were inferior, so there was nothing more to say.
"Since Captain Kyōraku is so warmly inviting, I will naturally accompany you to the end. Oh right, Captain Unohana and Captain Soi Fon, you should come too."
Tenya smiled and nodded, then looked towards the two female Shinigami.
"You..."
"Are you back to your old habits?" Rukia's lips twitched as she watched.
"Heh heh." Unohana smiled brightly, accepting his invitation.
"Interesting." Soi Fon respected those with strength and also did not refuse.
Just like that, the tense atmosphere between the two sides suddenly eased.
