Bang… bang…
Naruto launches a flurry of attacks and smashes Satori into the mountain. He lands beside the giant crater on the ground and glances at the cloud of dust and smoke raised by his previous attacks.
HAHA… HAHA…
A peal of chaotic laughter greets them as Satori flies out of the crater with no apparent damage to its body.
"Embracing your emotions…"
He charges up a giant sphere of destructive negative chakra.
"Don't give me that bullshit!"
Satori spats the giant volatile sphere toward Naruto. Naruto stretches his right hand and creates a giant rasenshuriken t counter Satori's attack.
Fwoosh…
Bang… BOOM…
Both attacks collide in the air and create a powerful torrent of energy that sweeps everything in the surrounding. The powerful explosion blows away the top of the mountain and creates a maelstrom of turbulent energy that ravages everything in its vicinity.
Whoosh…
Satori charges out of the energy surge and attacks Naruto with a kick. Naruto crosses his arms to block the attack.
Bang…
The heavy impact sends him flying across the air. Naruto tumbles through and barely stops himself after flying for a short while.
"Naruto!"
Sasuke appears beside Naruto and provides himself a platform to stand with his Susanoo. The giant Susanoo flaps its wings and charges toward Satori.
The swords of the Susanoo shimmer with energy as Sasuke slashes out swift crescent blades of energy toward Satori.
Satori confronts the crescent blades head-on. It stretches out its left claw.
WHAM…
A crimson surge of negative chakra encases his left claw. Satori performs a vertical sweeping motion and destroys the incoming attack. While destroying Sasuke's attack, it flaps its wings and dodges sideways, avoiding Sasuke's stab.
BANG…
Naruto lands a heavy blow on Satori from his blind spot and sends him tumbling down to the ground.
"Cho-Ōdama Rasenshuriken,"
Naruto creates a giant rasenshuriken almost triple his size and throws it at the ground.
BOOM…
A hurricane of wind blades appears at the point of impact and generates a spherical tornado of destruction with countless wind blades that destroy the ground to reveal a smooth dome-shaped crater on the ground.
Spurt… spurt…
Multiple laceration spurt blood from Satori's body. However, soon a scarlet glow envelope Satori's body and rapidly heals his wounds.
"That's…"
An ugly expression appears on Naruto and Sasuke's faces as Satori charges toward them with replenished vigor.
Back at the prison grounds,
Sakura's and Ino's healing slightly stabilizes Mui's injury.
"I am feeling slightly better!"
Mui shakes his head and slowly stands up. He turns towards the Box of Ultimate Bliss.
"Satori won't stop unless we seal the box of Ultimate bliss. Back in ancient times, the members of my clan paid an astronomical price to seal this monster in the box. Even though Satori has regressed in strength throughout millennia, it's still impossible to kill him as long as this box exists."
"Then how do we deal with this monster if we can't even hit it, much less kill him for good? At this rate, this monster will escape to the rest of the world and create havoc everywhere it goes. The elders of the fruit faction will achieve their goal of the destruction of the other nations." Shikamaru questions him in an urgent tone.
"There is a method!"
Mui slowly drags his body toward the giant box.
"What method?"
The rest of the shinobi turns towards him.
"It's this seal!"
He points towards the sealing scroll in Ryūzetsu's hand.
"But didn't she try it earlier? This sealing formation is not strong enough to contain that monster." Choji argues.
"No, this seal is incomplete!" Mui shakes his head.
"We have to inscribe the complete seal and perform the secret sealing ritual of my clan to seal the box. The sealing scroll in the Flower faction's hand is a weaker version of the real seal. Also, it was because of this reason that the Fruit faction wanted to ally with my clan."
Mui stands in front of the box with the sealing scroll in his hand. He infuses his chakra in the sealing scroll and lays it on the ground. A framework of giant fuinjutsu formation appears on the ground.
Mui infuses some chakra in his finger and inscribes a rune on the ground to align it with the chakra circuit of the sealing scroll.
"I have some knowledge of Fuinjutsu. I will help with the inscription." Ayaka offers her help.
Mui turns towards her and is slightly surprised to hear a little girl claim proficiency in Fuinjutsu.
"Alright, inscribe a Tenki node on the west side of the sealing scroll. After that, inscribe a Tsuchi node on the east side. As for the remaining directions, inscribe Godai nodes at them except for the north and south side, since their inscription is already on the scroll. I will inscribe the Jinrui gate in the center and connect all nodes with inscriptions." Mui issues a series of commands to Ayaka.
"All right!"
Ayaka nods in affirmation and inscribes the sealing runes according to Mui's command. Mui also quickly inscribes the runes in the fuinjutsu formation. Surprisingly enough he is a grandmaster in Fuinjutsu.
Mui raises his head once to glance at Ayaka's progress. His eyes widen in surprise at the rate of Ayaka's progress.
'This little girl is a prodigy. She is already a Fuinjutsu grandmaster at such a young age and her attainment in Fuinjutsu is even greater than mine. If not for the specific nature of this seal, I am afraid she would inscribe it much faster than me.' Mui also increases his pace.
While inscribing the seal, Ayaka frowns slightly as she infers the fuinjutsu formula in her mind.
'This seal is slightly unusual. The positions of nodes are reversed. Normally, the heaven node should be in the center, but in this seal, the Jinrui node is in the central gate position. Although the circuits of this seal are unique, they require a huge amount of chakra to activate. I wonder if even have enough chakra to activate this seal.'
Ayaka ponders as she completes the seal.
'Ayaka, how long will it take?' Sasuke's desperate voice rings in her head.
'I am almost out of chakra fighting this monster.' He adds.
'Nii-san, we are almost done with the seal. Lure that monster to this seal. We will seal it in the box.'
'Alright!'
Mui also completes the final inscription.
"Everyone, occupy a node to supply chakra to activate the seal. I will take the central node to control the formation." Mui instructs.
"Alright!"
Sakura, Hinata, Ayaka, Choji, Shino, Neji, Ino, Kiba, and Ryūzetsu occupy a node according to Mui's instructions. Only Tenten, Lee, and Shikamaru are without any nodes since they have the lowest chakra reserves among the group.
They infuse chakra into the seal and the sealing circuit of the seal lights up.
"Nii-san, we are ready!" Ayaka sends a signal to Naruto and Sasuke.
Naruto and Sasuke glance at each other and nod. Both of them increase their pace of attack and slowly lead the battle back toward the prison grounds.
Hmm…
Soon, Satori notices something amiss. He turns around and notices the giant sealing formation.
"You want to seal me back into that box?" Satori's countenance changes.
"I was freed after so many centuries, and you want to reseal me into that box?"
SHOOM…
Satori releases a burst of negative chakra from its body and pushes them away. It charges up a giant sphere of negative chakra and throws it toward Naruto since Naruto is the only person who can land a blow on him and hinder his movement.
Swish…
Sasuke flies in front of the giant explosive chakra and blocks it with Susanoo.
BOOM…
The sphere explodes and engulfs Sasuke in a violent surge of energy.
"SASUKE!" Sakura screams in shock.
Satori uses this opportunity to escape in the other direction.
However,
"Storm Release: Four Direction Tempest Prison,"
A giant cage of lighting encases Satori and seals his escape route. Satori turns around and notices Ayaka completing her hand seal.
Anger surges in Satori's eyes. It infuses negative chakra in its hand and shatters the prison with a swipe of its hand.
"Do you think this can stop me?" He mocks.
"I didn't mean to stop you. I just wanted to buy some time." Ayaka grins as Mui claps his hand and infuses his chakra into the Fuinjutsu formation to activate it.
WHAMM…
A gigantic pillar of blue energy rises from the center of the seal and slowly encases the area around the group. Satori flaps his wings and attempts to escape from the seal.
"I won't let you!"
Naruto jumps out of the dust and smoke while supporting Sasuke with one of his shoulders.
"Adamantine Sealing Chains,"
Multiple giant chakra chains escape from Naruto's body and bind Satori's body and pull it toward the center of the seal. The sealing properties of the seal restrict the negative chakra of Satori to some extent.
"Old Man Mui, do it now!"
Naruto yells at Mui as the latter slices his palm and drips his blood on the center of the seal.
