Using Kamui for Kirin is consuming a lot of Kakashi's Chakra.
This is the case for Kamui. The faster it is used and the larger its scope, the more Chakra will be consumed.
"Kakashi! Your body is perfect! Hahaha, as expected of the Kekkei Genkai I left to the end."
Hiruko exclaimed excitedly. To him, victory is already within his grasp.
Kakashi took a deep breath and the Sharingan restored the shape of the three tomoe again.
Hiruko was slightly a little surprised when he saw this, and then mocked: "It seems that you can't use that Ninjutsu at will. You can't even maintain the shape of Mangekyō, right?"
Kakashi ignored Hiruko's mockery. The situation right now has developed into the direction he least wants to see.
Hiruko's strength seemed to be above his expectations.
The fusion of the four Kekkei Genkai not only allowed Hiruko to master the four Kekkei Genkai, but also greatly increased the power of these Kekkei Genkai.
The power exerted is more than four times stronger than the original one.
This is just four Kekkei Genkai.
If he let Hiruko get the fifth Kekkei Genkai, his power will probably be doubled or even multiplied by several times, achieving a perfect state.
It is no wonder that Hiruko has such confidence to challenge the Five Great Countries by himself.
If Hiruko really succeed in swallowing Kakashi, he indeed has such an ability.
At this moment, temporarily suppressed the side effects of using Kamui, and slightly shook his right hand. The Millennium Sword suddenly appeared, and was flashing with lightning.
"It seems that you still haven't given up. Let me guess what you are going to do next. Using the speed you are proud of? Swordsmanship? Or maybe Lightning Release?" Hiruko continued to mock.
Kakashi narrowed his eyes and used Shunpo!
In an instant, Kakashi turned into thousands of afterimages, as if attacking Hiruko from all directions.
"Too slow! Not enough!"
The Millennium Sword appeared on the left side Hiruko and cut from right to left.
Hiruko took a step back and dodge it.
'Sure enough, ordinary Shunpo can't keep up with his Swift Release.'
'Then, let's use this one.'
Lightning flashed from the soles of Kakashi's feet, and his speed suddenly doubled!
Like a fang, the Millennium Sword slashed towards Hiruko's right arm.
The sound of steel colliding rang!
The Millennium Sword, who can cut iron like tofu, was able to slash Hiruko's right arm, but there was no trace at all!
Kakashi's pupils shrank, and Hiruko smiled.
"Steel Release: Impervious Armour!"
Hiruko then bent his waist, and his left fist was thrown!
Hiruko's left fist hit Kakashi's chest!
Kakashi was directly blown away and fell to the ground, right next to Naruto and Sasuke.
Hiruko didn't take advantage of the situation to pursue Kakashi, but said triumphantly: "This Steel Release can make my body harder than steel. You can't pierce my skin with that sword or any other weapon!"
Kakashi spit out blood and grabbed his chest with his left hand.
Naruto and Sasuke rushed over.
"Kakashi-sensei, are you okay?" Naruto asked worriedly.
Sasuke also looked at Kakashi worriedly.
Kakashi shook his head and wiped the blood from the corners of his mouth.
"I'm fine, it's just a little injury."
Kakashi then stood up again, 'The punch just now was really too strong.'
'That feeling is like being hit by steel in the chest.'
'I couldn't react to that attack, so I took that punch solidly.'
At this moment, Kakashi looked at Hiruko more solemnly.
'I originally thought that Hiruko was powerful, but he shouldn't be this strong.'
'After all, he was the guy who was defeated by Naruto with a Rasenshuriken easily in the original work.'
'But now, it seems that this Hiruko is a bit too strong.'
'With the Swift Release, his speed is not inferior to mine.'
'With the Steel Release, his body endurance and strength are amazing, much stronger than Kakuzu's Earth Spear.'
'That punch, even if it wasn't as fierce as Tsunade-sama's punch, was not far off.'
'With the Dark Release, almost all ninjutsu was ineffective.'
'Storm Release is also a terrifying attack method.'
'At this time, the dark clouds in the sky still did not disperse yet.'
Kakashi couldn't help but being surprised when he thought of this.
'The Storm Release just now has not been released yet!'
Because of Kirin, the Storm Release used by Hiruko just now was interrupted, but it hasn't stopped yet.'
'Looking at the current situation, it is still continuing to condense.'
'If these thunderclouds are allowed to condense, power of the formed Storm Release will be even more terrifying than the Kirin!'
'Judging by the strength accumulated in the sky, the scale of this Storm Release would be even more terrifying than the Kirin.'
Seeing that Kakashi is looking at the sky, Hiruko sneered and said: "Have you found it out? Yes, my Ninjutsu is not over yet. When that Storm Release falls, it will be the time when your lives will end. You can't escape! The entire Mount Shumisen is within the scope of this Ninjutsu! Hahaha."
Hiruko shouted and laughed wildly, as if victory was in sight.
The three were shocked when they heard this.
Kakashi looked at Naruto and said, "Naruto, can you still use Chakra now?"
'If Naruto can use the Rasenshuriken, perhaps this battle will be much easier.'
After all, Hiruko is unable to absorb complicated Ninjutsu like the Rankshuriken.
Because of his lack of control!
After hearing this, Naruto tried to move the Chakra inside his body, and immediately felt a tingling pain.
"No, Kakashi-sensei. I was previously injured by that Hiruko's Ninjutsu, my body has not recovered yet, and I still can't use Chakra right now. Sasuke, what about you?"
Sasuke also shook his head, as his condition is the same as Naruto.
The numbness caused by the basic fusion of Rasengan and Chidori was so strong that they could not recover for a while.
Kakashi's expression became even more solemn when he heard their answers.
'It seems that I can only rely on myself.'
'It's just that it will be more risky.'
"Naruto, Sasuke, you should be careful now. I may not be able to take care of you two now." Kakashi whispered.
Naruto and Sasuke looked solemn, as it was the first time they saw Kakashi so serious.
No matter how powerful the enemies in the past were, Kakashi always seemed to be indifferent to them.
But this time, both of them felt that Kakashi was really serious.
"The time is almost up. Now, feel the power of this boundless Storm Release! Ranton Ōgi: Rankiryū!" (Storm Release Secret Technique: Demon Dragon Storm)
Hiruko shouted softly, and the thunderclouds in the sky become even more active.
At this moment, there are countless thunders rolling in the dark clouds!
Suddenly, a huge blue dragon head emerged from the black clouds!
The dragon's roar is shaking the sky!
At this time, Kakashi's eyes were fixed on the giant dragon.
The silver-white Cursed Seal hidden in his back suddenly started spinning.
And then, powerful strength poured into Kakashi's body!
"Sage Mode! Activate! "
(A/N: Maybe everyone thinks that Hiruko is very weak as he was defeated easily by Naruto's Rasenshuriken. But I think that an enemy that has fused four Kekkei Genkai and forced Konoha to sacrifice Kakashi is not weak. In the original work, the reason why Hiruko can't absorb Rasenshuriken is because of Main Character's Plot Armor.)
