Naruto: The Strongest Kakashi

Boom!

The terrifying red light beam rose to the sky!

Sasuke and Naruto, who were supporting each other, just walked through the gate, and saw the red light beam soaring into the sky.

"What is going on?" Naruto asked in surprise.

Sasuke also saw the red light beam and froze in place.

The two looked at the gate again and there was a constant red light.

"Not good! It's going to explode!" Sasuke's scarlet eyes moved and he made a surprising conclusion.

"What! Kakashi-sensei is still inside!" Naruto said worriedly.

As soon as Naruto's voice fell, the door slammed open, and a figure that they all knew very well came out from inside.

"Kakashi-sensei!" Naruto said in surprise.

Kakashi looked at the two with a smile, and then, the two ran towards Kakashi one after another.

Boom!

The castle behind them exploded and turned into ashes, forming a terrifying air wave.

Lightning flashed under Kakashi's feet and they quickly left the place.

If he is late, he would get caught in the aftermath.

Kakashi will be fine, as with his excellent physique, even if he gets caught by it, it doesn't matter.

But Naruto and Sasuke are different. The two are now injured. If they got caught by that, they will be in trouble.

Kakashi landed and put the two down.

"Are you okay?"

Both Naruto and Sasuke shook their heads.

"We're fine."

"That's good." Kakashi smiled and his eye turned crescent.

"Kakashi-sensei, are you okay? What happened in the end?" Naruto asked.

"Ah, let's talk about this later, for now, let's take care of that guy first."

Kakashi's gaze looked at Hiruko in the distance. At this time, he was standing on the wreckage of the old castle.

The originally old castle has been razed to the ground by him.

Hearing this, Naruto and Sasuke also looked at Hiruko.

Originally, he looked a bit handsome, but now, he was like a monster.

There is also a gap in his chest.

"Kakashi, be one with me obediently. You are not my opponent at all."

"How do you know if we don't try!"

"I will make you regret it!"

Hiruko said. And then he bit his right thumb and formed hand seals with both of his hands!

"Kuchiyose no Jutsu!" (Summoning Technique)

With a bang, a huge summoned beast appeared in front of everyone.

With wings on his back, it looks like a dog, but there are also snake heads entangled in his body.

"That..." Sasuke was stunned. He felt that the summoned beast in front of him right now seemed to be a combination of the summoned beasts used by the three people before.

At the same time, the three psychic beasts, that were fighting Jūgo, Karin, and Sakura, also disappeared.

Before that, the three Shinobi had already merged with their summoned beasts.

"What happened? Why did it suddenly disappear?" Jūgo wondered.

'This way of disappearing is caused by being summoned. There was such a big disturbance on the mountain just now. Is it because Naruto and the others have gone to fight the leader? I have to go quickly.'

Thinking about it, Jūgo quickly ran towards the top of the mountain.

Karin and Sakura reached the same conclusion and ran towards the top of the mountain.

"Kakashi-sensei, what kind of monster is that?" Naruto asked in surprise.

Kakashi frowned slightly without answering.

'The strength of this big guy does not seem to be weak, and Naruto and Sasuke are also still injured and may not be able to hold it.'

'I have to deal with Hiruko, and I won't be able to deal with this big guy.'

'In that case, I should just call out that guy.'

'Having said that, that guy hasn't fought alongside me for a long time.'

After thinking about it, Kakashi quickly bit his right thumb.

At the same time, he also quickly formed hand seals!

"Kuchiyose no Jutsu!" (Summoning Technique)

Bang!

A huge smoke scattered, and a huge black three-headed dog appeared below Kakashi.

"Kakashi, long time no see. Why did you call me this time?" Nanairo asked.

"Nanairo, can you take care of that guy for me?" Kakashi pointed to the big dog with the wings in the distance.

Nanairo moved his gazes, and then, there was a hint of excitement in their eyes. He then said. "Haha, he looks very resistant. He is a good opponent. It seems that I can finally move my muscles and bones after such a long time."

"Good, then I will leave it to you."

After Kakashi finished speaking, he jumped off the head of the three-headed dog and landed in front of Naruto and Sasuke.

Naruto looked surprised and asked, "Kakashi-sensei, is that your summoned beast? Aren't your summoned beasts only Pakkun and Tetsuya?"

Sasuke on the side was also curious.

"Tetsuya and Pakkun are support-type dogs, and Nanairo is combat-type dog. Just like your toad race, they have a clear division of labor."

"So it's like that. Amazing!" Naruto said excitedly.

Sasuke also looked at the huge three-headed dog longingly.

His intuition tells him that this summoned beast is very strong.

Sasuke also wants a powerful summoned beast like this.

But unfortunately, the Uchiha Clan does not have such a summoned beast.

Even if it is Itachi, he only uses crow as his summoned beast.

Kakashi naturally couldn't care about Sasuke's small emotions at this time as he still had more important things to do.

Nanairo rushed up forward and fought against the big dog with wings on its back.

It seems that the winner won't be determined for a while.

Kakashi now focused his attention on Hiruko.

"Hiruko has already absorbed four Shinobi with different Kekkei Genkai. His perfect body has gradually formed, but because he still hasn't fuse with my body, his body still has flaws. I just discovered that the flaw in Hiruko's body is on its chest, so our attack target is there!"

"Yes, Kakashi-sensei!" Naruto and Sasuke answered in unison.

Kakashi nodded, and used Shunpo to directly rushed towards Hiruko!

A kunai suddenly appeared on his right hand, and then Kakashi appeared on the side of Hiruko, and stabbed him with his kunai!

A sneer appeared at the corner of Hiruko's mouth, and at the next moment, his figure disappeared from that place!

'He's fast!'

Kakashi's pupils shrank, and Hiruko suddenly appeared behind him, kicking him on the back.

Kakashi was blown away under such force and hit a rock.

"What? Kakashi-sensei's speed was actually defeated by that person!" Sasuke said in surprise.

"Kakashi, for me who has Swift Release, your speed is too slow. You should just give up obediently! Ranton: Raiunkūha (Storm Release: Thunder Cloud Inner Wave)!"

Hiruko said as he finished forming hand seals. And in an instant, countless thunderclouds was formed and rushed into the sky.

In the sky, the thunderclouds are constantly flashing, and thunder may fall at any time.

"This is not an ordinary thundercloud but a cumulonimbus cloud that can grow through Chakra. The place covered by this cumulonimbus cloud has become my territory!"

Kakashi got up from the rock and coughed twice.

The kick just now is not light, so Kakashi's body was a little injured.

"I didn't expect the speed of the Swift Release would be so fast. Or maybe, after Hiruko swallowed the Swift Release Shinobi, the ability of the Swift Release has become even better. It's amazing." Kakashi murmured.

At this time, Hiruko has four Kekkei Genkai, and he can use all of them proficiently, and he may be even better than the original user.

This is why Kakashi can't react before.

After all, the original Swift Release shouldn't be able to keep up with his speed.

"It seems that I need to be faster."

Kakashi looked at the thunderclouds in the sky and a slight smile appeared on his face.

"Hiruko sure is kind. I haven't used this technique for a long time now."

Kakashi jumped up and stood on the side of the stone, condescendingly.

Seeing this, Hiruko said: "Kakashi, you still haven't given up yet? You can't beat me!"

"It's still too early to say that. Since you have created those thunderclouds, I will use it without reservation!"

After Kakashi said that, Chidori appeared on his right hand!

"What are you going to do!" Hiruko exclaimed in surprise.

Sasuke was stunned when he saw this, 'Is Kakashi-sensei going to...'

His right hand was raised high, and his scarlet left eye looked at the thunderclouds in the sky.

"Lightning Release: Kirin!"

With Kakashi's soft shout, a blue behemoth with a terrifying look appeared in the sky!
