A few hours earlier in a temple at Genbu Island,
"Yo-Yo Naruto! Just focus your chakra with a mix of blue and some red hue."
"Ugh… but that doesn't explain anything!"
Naruto scratches his head as he collects dense red and blue orbs of tailed-beast chakra in his Kurama Chakra cloak.
"Kurama, I already have you to fire a tailed-beast bomb whenever I need it. So, why must I learn to make one while in the chakra mode?"
The balance of blue and red dense chakra orbs in Naruto's hand disrupts and the unstable orb glows with a bright hue.
"AH! It's about to explode!"
Naruto hurriedly tosses it out towards the sky.
BOOM…
A powerful explosion goes off in the sky and the entire island shudders from the shockwaves.
ROAR…
A loud roar echoes in their ears. Naruto blocks his hands with his ear while Bee takes our earplugs and inserts them in his ear.
"What was that noise?" Naruto enquires.
"It's the turtle of this giant island. The explosions woke it up from its sleep." Bee informs him.
"Huh! You mean this entire island is on the back of a turtle?" Naruto enquires with wide eyes.
"That's exactly what I mean!" Bee nods his head.
"Look, you can even hear his heartbeat if you pull your ear closer to the ground." Bee lies down on the ground.
"Woah! Amazing!" Naruto copies Bee's movement and places his ears against the ground.
Lubdub…
A faint sound of a heartbeat reverberates throughout the entire island.
"I can hear it!" Naruto nods his head in fascination.
Ahem!
Kurama and Gyuki clear their throat to pull their attention.
"Naruto, any way you must learn this technique since that's what your Izuna-nii san expects from you. Before he left, he specifically instructed me to oversee your training. If you give up now, then your Nii-san will be disappointed in you." Kurama sighs and feigns helplessness.
"What? Really?! Naruto's eyes widen slightly.
"Yes, of course! I have no reason to lie to you." Kurama nods his head.
"Kurama, transfer some of your chakra, and let's continue to practice." Naruto pumps his fist.
"Yay! That's the way, Naruto." Bee fists bump with Naruto.
Naruto continues to experiment with the dense blue and red chakra.
He practices for another hour with three more explosions that annoy the Genbu turtle even further.
"Hehe… I will apologize to him later." Naruto scratches his head.
He extends his hand out and creates a Rasengan.
"Hmm… Kurama, Dad created Rasengan based on the tailed-beast bomb, right?"
"That's true! But his earlier iteration was quite unstable, similar to your attempts. I saw the entire process with my eyes." Kurama nods at him.
"However, it was your Izuna Nii-san who recommended Minato to add rotation to the chakra to stabilize it," Kurama adds.
"Hmm… Then what if I also add rotation to these positive black chakra and negative red chakra? I have got the right proportion down to Eight portions of Black chakra and two portions of red chakra. However, the jutsu is unstable. What if I decrease the proportion of black chakra by a little and increase the proportion of red chakra at the same time while adding rotation to the chakra?" Naruto inquires.
"That's worth a try!" Kurama ponders for a second and nods his head.
"Alright!"
Naruto takes a deep breath and extends both his hands. He gathers the black chakra in one hand and the red chakra in the other hand.
"Rotation!"
Naruto slowly gathers the black and red chakra and adds rotation to it. The black and red chakra slowly coalesces into a sphere.
"It's working!" Naruto yelps in surprise.
Soon, a stable orb of Black and Red chakra appears in Naruto's palm.
"It's heavy!" Naruto almost drops the orb, much to Bee and Gyuki's horror.
Naruto lifts it up in his palm and stares at the revolving chakra within the orb.
"What should I call it? It's a Rasengan but also a tailed-beast Bomb." Naruto ponders.
"Then what about 'Super Mini-Tailed beast Rasengan'?" Bee suggests a name.
Gyuki stares at him and sighs. He turns towards Kurama but is confused to see the latter with a similar expression. Soon enough,
"Wow! That's a super cool name, Octo Pops." Naruto gives a thumbs-up to Bee.
"What's with this idiotic Duo?" Gyuki sighs helplessly.
"Alright, Naruto! Let's test the power of this new jutsu?" An octopus tentacle pops out of Bee's back and pulls a lever on the walls of the temple.
The liver activates a contraption that reveals a hidden chamber.
"Alright, you can throw your jutsu inside that room!" Bee signals to Naruto.
"Umm… will it be alright if throw this in there? I mean… won't be…"
Naruto makes the gesture of an explosion.
"It's fine! There are several powerful barrier formations inside that room. Bee also used to train his tailed beast transformation within that room." Gyuki assures him.
"Alright!" Naruto tosses the Super mini-tailed beast Rasengan into the room.
A few seconds later,
BOOM…
A flash of bright light and the sound of a dull explosion echoes within the walls of the temple. A few seconds later, smoke escapes from the confinement of the room.
A fuinjutsu formation appears on the outer walls of the room.
"Huh! This fuinjutsu formation…"
"Hmm… that's a pretty nifty technique!" Bee nods his head and pens down something in his small notebook.
"I even got the inspiration for my song from this."
"Bee, you idiot! Naruto's attack broke the isolation formation of this temple."
Suddenly, an influx of chakra from various senses overwhelms Naruto's heightened sense of perception.
"This chakra…"
Naruto closes his eyes as he senses several chakra signatures engaged in a battle.
"What… what's going on?" Naruto's expression changes as he closes his eyes and analyses the sudden influx of information.
"Sigh… it's too late. The cat is out of the bag!" Kurama shakes his head as he also sensed what Naruto sensed earlier.
Naruto sits down with his legs crossed and soon enters into Senjutsu mode.
A few minutes later, he opens his eyes and a bright glow flashes past his eyes.
"My friends… my families…. They are fighting for their lives out there, while here I am…" Naruto clenches his fist.
He walks towards the exit of the temple.
"Yo, Naruto! Where are you going?" Bee questions him.
"Of course, it's obvious. I am going to help them with the war." Naruto speaks with a resolute expression.
"I can't let you go to battle or else I will get the Iron Maiden Grip of my brother!" B crosses his arm.
"Then try to stop me if you can!"
Shoom…
Swoosh…
Naruto's figure flashes with a bright yellow, orange glow. At the same time, Bee also shapes his fist into a hammer and smashes it at Naruto's position.
Fwoosh…
In the next second, Naruto reappears at the entrance of the temple.
"This speed!"
Bee's eyes widen in surprise as a memory flash past his mind.
"Fool Ya Fool! That was really cool!"
Bee shakes his head and chases after Naruto.
Sigh…
Gyuki sighs and shakes his head.
"You are going to get scolded by A again."
"Everything will be Daijoubu! I will somehow convince him." Bee gives a thumbs up.
Outside the Temple,
"Naruto, Stop!"
A group of shinobis from Konoha attempts to stop Naruto outside the temple.
"So, those peeping eyes… it was you guys!" Naruto glares at the group.
"Huh! Iruka-sensei! What are you doing here?" Naruto recognizes Iruka within the group.
"Naruto, please return inside! I can't allow you to walk out of this room." Iruka shakes his head.
"Sensei, but my friends…"
Sigh…
Iruka sighs and speaks.
"Naruto, Akatsuki wants to capture you and Lord Bee. It's for this reason they have waged a war on the shinobi world. The rest of the villagers and shinobi are fighting to protect you both. So, please don't let their sacrifice go to waste." Iruka attempts to convince Naruto.
"Iruka, why did you?"
"It's fine! He has already sensed the situation in the war." Iruka shakes his head.
"Iruka-sensei! What if I tell you, you can't stop me?"
"Then I will at least give it a try?"
Iruka takes a step forward and activates the restrictive fuinjutsu formation on the floor of the temple. The sealing jutsu binds Naruto in a place.
Naruto glances at the sealing formation and shakes his head.
"It's not enough to stop me."
"At least we can try!" Iruka smiles dryly as the very next moment Naruto shatters the seal with his overwhelming chakra.
Shoom…
His figure disappears from their vision.
"Damn it! I have to inform the rest." One of the shinobi takes out a communicator and informs the barrier division outside the temple.
