At that thought, the murderous intent in Uchiha Shin's heart was instantly ignited.
However, he did not rush out immediately to kill Uchiha Itachi.
He prepared to give himself a boost first.
As the saying goes, to do a good job, one must first sharpen one's tools.
It would only be easier to deal with Itachi after he had first raised his own strength.
"Permanent Amplification seems to be like the permanent Kotoamatsukami; after use, it requires a long time to recover. I wonder if my Rapid Regeneration can change this phenomenon," Uchiha Shin murmured to himself.
The information his Mangekyo Sharingan had just fed back to him let him understand that while Permanent Amplification was powerful, it was not without a cost. After being used, it required a long time before it could be used again.
Therefore, before he was certain whether Rapid Regeneration could help shorten the cooldown of the Permanent Amplification ability, he was very cautious about this first self-amplification.
"Which one should I amplify first?"
"Ninjutsu?"
"Genjutsu?"
"Taijutsu?"
"Comprehension?"
"Chakra?"
"Hmm, let's go with chakra!"
Because he was about to go to war with Itachi.
Therefore, his choice at this moment must be the one that would help him the most.
Although Ninjutsu, Genjutsu, and Taijutsu would be of considerable help in the upcoming battle.
But Itachi was no ordinary opponent.
Once he activated his Susanoo.
Ordinary techniques would not be of much use.
Even a tenfold amplification might not be effective.
Comprehension was a good choice.
Under normal circumstances, Uchiha Shin might have chosen it first.
But now, he was about to face a major battle.
The usefulness of comprehension was limited at this time.
After thinking it over.
Uchiha Shin felt that amplifying his chakra reserves would be the most helpful at this moment.
After all, when two people can both activate Susanoo, the one with more chakra will undoubtedly have a stronger, fiercer, and more durable Susanoo.
Thus.
Uchiha Shin no longer hesitated.
He directly used Permanent Amplification on his chakra.
As a crimson light flashed from the five-pointed star Kikyo pattern in Uchiha Shin's right eye.
BOOM!
A terrifying blue aura erupted from within Uchiha Shin's body.
It made Uchiha Shin look like a Super Saiyan powering up.
His aura overflowed!
"So strong!!"
Feeling the abundant chakra within his body.
He was amazed.
If.
The Uchiha Shin who had not awakened the Mangekyo Sharingan had chakra equivalent to two Kakashis.
Then, after awakening the Mangekyo Sharingan, he possessed about seven Kakashis worth of chakra.
Now, after the permanent amplification of his chakra.
At this moment, his chakra reserves were at least above seventy Kakashis.
A full tenfold increase.
This amount of chakra might not compare to the Nine-Tails Jinchuriki, Naruto.
But it far surpassed that of an ordinary Kage-level powerhouse.
Itachi simply could not compare.
However, he also knew.
The outcome of a ninja battle was never determined by chakra reserves alone.
"A tenfold amplification. According to the normal ratio, my Permanent Amplification Mangekyo should have a ten-year blank period where it cannot be used."
"But, I can feel that under the repair of Rapid Regeneration, the ocular power of my Permanent Amplification Mangekyo is recovering rapidly. At this rate, if nothing unexpected happens, it should be usable again by tomorrow..."
After using the Permanent Amplification Mangekyo.
The Rapid Regeneration ability actively surged into his right Mangekyo Sharingan.
It rapidly repaired the deficit of the Permanent Amplification Mangekyo.
After a quick assessment.
Uchiha Shin came to a delightful conclusion.
...
At this time, the Uchiha clan was in dire straits.
Uchiha Shin did not get lost in the joy of his skyrocketing strength.
He quickly came back to his senses.
"Thirty years the river flows east, thirty years the river flows west. Uchiha Itachi, you beast, since you couldn't kill me, then it's your turn to die."
With that, Uchiha Shin burst out of his house.
And charged swiftly towards Uchiha Itachi's location.
...
A hundred meters away from Uchiha Shin's house.
Another house.
Itachi had just finished killing a family of five.
A fifty-year-old mother.
A twenty-seven-year-old young man.
A twenty-five-year-old young woman.
A five-year-old child.
And an infant less than a month old.
Perhaps, in this world, killing an infant less than a month old might be seen as the greatest mercy.
But in truth, anyone who could do such a thing was an inhuman beast.
After Itachi cleanly wiped out the family of five.
He didn't even spare them a second glance and turned to leave.
Preparing to proceed to the next house.
However.
Just as he stepped out of the house's main gate.
A figure shot over at high speed.
"Uchiha Itachi, you motherfucker, die you beast!"
The person was Uchiha Shin. As he roared.
He quickly formed a hand seal.
"Fire Style: Great Dragon Fire Technique!"
Released with his abundant chakra.
A massive fire dragon, tens of meters long, manifested and surged mightily towards Uchiha Itachi.
"Uchiha Shin? You're not dead?"
A hint of surprise flashed in Itachi's eyes.
At the same time, his hands flew through seals!
"Fire Style: Great Dragon Fire Technique!"
As the technique was completed, a fire dragon, no weaker than the one Uchiha Shin had released, spewed from Itachi's mouth.
BOOM—!
The two fire dragons collided.
Directly producing a massive explosion.
Flames instantly engulfed a radius of several dozen meters.
Only after several seconds did the flames finally dissipate.
Leaving behind only a ten-meter-wide crater and the ruins of destroyed houses.
At the same time.
All the Uchiha clan members who had not yet been killed were startled by this huge noise.
Many people rushed out of their houses.
"What's going on?"
"It seems like someone is fighting within the clan grounds!"
"Could it be Sarutobi Hiruzen and the others have come to kill us?"
"Don't speak nonsense about things you're not sure of."
"Let's go, let's go check it out!!"
After the Uchiha clan members met up.
Following a brief discussion, they rushed towards the commotion.
After Itachi blocked Uchiha Shin's attack.
He also realized that things were not looking good.
His face darkened slightly.
"Not good, I've alerted everyone."
"This won't do, I have to end this quickly!"
With that, Itachi called out into the empty air:
"Madara, please hold off the others for me. I'll deal with Uchiha Shin first!"
At that moment, the space distorted.
Then, a man wearing a mask appeared out of thin air on a rooftop not far from Itachi.
"Next time, strike a heavier blow!" Obito glanced at Itachi and said indifferently.
"Although I don't know how he survived, this kind of thing will not happen a second time," Itachi said in a deep voice.
"Fine!!"
Obito replied.
Then he cast a playful glance at Uchiha Shin.
He was curious as to how Uchiha Shin could recover after having his heart and throat pierced without using Izanagi.
However, he also knew what was important.
He didn't waste his breath with Uchiha Shin.
He directly used Kamui and disappeared from the spot.
He went to intercept the gathering Uchiha clansmen.
