The sudden appearance of the system's voice caught Uchiha Sora off guard.
Come to think of it, it had been a while since he last heard its voice.
He wondered what it was coming out for at this time?
It didn't seem like he had been provoked or anything?
However, the system soon gave him the answer.
"Ding! Due to the host's intense battle with the Tailed Beast and sensing the vastness of the Tailed Beast's Chakra, your Chakra feels its own insignificance and is determined to work twice as hard! The automatic cultivation speed of your Chakra Concentration Technique has doubled!"
"Ding! Under the urging of your Chakra Concentration Technique, your physical training refuses to fall behind; its automatic cultivation speed has doubled!"
"Ding! Under the urging of your Chakra Concentration Technique, your spiritual energy refuses to slack off; its automatic cultivation speed has doubled!"
Hearing this series of prompts, Uchiha Sora couldn't help but be overjoyed!
Great! His Chakra was quite self-motivated!
He had been thinking that his current Chakra was still a bit low compared to a Tailed Beast and was worrying about having to use it more sparingly in future battles. He hadn't expected the system to be so considerate and provide a prompt immediately!
The acceleration of the Chakra Concentration Technique, physical training, and spiritual energy meant an increase in both the recovery rate and the upper limit of his Chakra reserves.
With the previous automatic cultivation speed, it would have taken Uchiha Sora at least two or three years to reach the level of a Tailed Beast. But now, with the acceleration, it would only take about a year!
This sensation of accelerated cultivation even allowed him to feel his spirit, body, and even Chakra recovery improving at a visible rate.
Although he had just consumed more than half of his Chakra, he now felt fully energized, without the slightest hint of fatigue.
While secretly rejoicing, Uchiha Sora didn't forget what he needed to do right now.
He crouched down, pulled open the Fourth Mizukage's eyelids, and aimed his Three-Tomoe Sharingan at the man's eyes. His Dōjutsu power surged, instantly entering the other's mind.
For those who didn't understand Genjutsu, dispelling the Fourth Mizukage's illusion would be very difficult. However, Uchiha Sora possessed the Sharingan and had learned many Genjutsu insights from Shisui. Furthermore, he was immune to Genjutsu himself, so his mastery of the art was beyond question.
It was one thing if the Fourth Mizukage's manipulation had gone unnoticed, but once the cause was clear, dispelling it was no problem at all for Uchiha Sora.
At this moment, within the Genjutsu space, Uchiha Sora intruded into the Fourth Mizukage's brain.
He clearly saw a faint fluctuation of Dōjutsu power on the Fourth Mizukage's brain, subtly altering the functioning of his cerebral organs.
This kind of change was something that even the victim themselves could not detect.
"Manipulation undetected even by oneself... this is exactly like Shisui's Kotoamatsukami!" Uchiha Sora murmured.
He tried to use the Dōjutsu power of his Three-Tomoe Sharingan to dispel that special energy, but found it quite laborious. It would likely take a significant amount of time.
"It seems I still have to use the Mangekyo's Dōjutsu power!" Frowning, Uchiha Sora activated his Hexagram Mangekyo. With the enhancement of the Mangekyo's Dōjutsu power, the potency instantly increased. Under the powerful Dōjutsu power and Uchiha Sora's Genjutsu expertise, the special Dōjutsu power entwined around the Fourth Mizukage's brain was utterly destroyed.
Manipulation dispelled!
Uchiha Sora breathed a slight sigh of relief and deactivated his Mangekyo.
His current Mangekyo was very precious; since it wasn't the Eternal Mangekyo, the more he used it, the more likely he was to go blind.
Therefore, he had to be cautious with every use, which was also why he hadn't activated the Mangekyo to deal with the Three-Tails.
Of course, there was another reason: to guard against the appearance of Uchiha Obito.
After all, the space-time ability of his Mangekyo was the ultimate counter to Obito.
He had to keep it rested and ready for when it was truly needed.
Meanwhile, somewhere in the Hidden Rain Village, Uchiha Obito, who was meeting with Nagato and Konan, suddenly sensed that the Genjutsu he had placed on the Fourth Mizukage had been dispelled.
His expression darkened.
He raised a hand to touch his left eye beneath the mask—the special Sharingan gifted to him by Uchiha Madara before his death.
"Who is it? Who could actually dispel the power of Uchiha Kagami's Dōjutsu?" Uchiha Obito's heart was filled with gloom.
"That's all for today. I have something to take care of!" He said to Nagato and Konan before activating his right eye's Kamui power, vanishing from their sight in an instant.
...
Within the Genjutsu space, after Uchiha Sora dispelled the Dōjutsu power, the Fourth Mizukage's consciousness awakened. He appeared before Sora and spoke slowly, "I never expected that I, a Perfect Jinchuriki, would be controlled by someone without even realizing it!"
"To think I fought so fiercely with you just now; I've truly caused you a lot of trouble!"
Although the Fourth Mizukage had been conscious while fighting Uchiha Sora, once Sora dispelled the Genjutsu manipulation, he naturally understood everything.
"It was also my oversight; I didn't realize you were being controlled either." After the Fourth Mizukage appeared, the Three-Tails Isobu also manifested in the Genjutsu space, speaking in a heavy voice, "Thanks to this human for helping us, though his hits really hurt."
Seeing the Three-Tails Isobu's dejected look, the Fourth Mizukage shook his head. "You're just too slow! Your IQ needs some work!"
"We Tailed Beasts aren't that smart to begin with," Isobu replied.
"Sigh, but for someone to bypass both our senses and use Genjutsu on me... that is definitely no ordinary illusion!" the Fourth Mizukage lamented.
Uchiha Sora nodded. "The opponent is also from the Uchiha Clan. It's likely some special Mangekyo Dōjutsu. You should be careful in the future."
"Thank you for the warning," the Fourth Mizukage said gratefully.
Suddenly, Uchiha Sora frowned. "It seems someone is coming!"
He instantly left the Genjutsu space and returned to reality.
The Fourth Mizukage also opened his eyes at the same time. Though his body was still in a weakened state, he struggled to stand up. Before he could greet Mei Terumī and the others, he looked toward the space not far ahead.
At that moment, a swirling ripple appeared in space, and a masked figure emerged before everyone.
It was Uchiha Obito, who had rushed over after sensing the Genjutsu had been broken.
"It's you!" The Fourth Mizukage recognized him immediately.
During the period he was being controlled, he had quite a bit of contact with Uchiha Obito, so he naturally recognized him.
However, the Fourth Mizukage did not know his true identity.
Uchiha Obito ignored the Fourth Mizukage, his gaze flickering as he stared at Uchiha Sora, his face behind the mask unreadable.
"Uchiha Sora, this was your doing!" He gritted his teeth, speaking each word with a cold, venomous tone.
In Uchiha Sora's eyes, the Mangekyo Sharingan activated. He stared at Uchiha Obito and chuckled, "I told you I'd play with you slowly. This is just the beginning. I hope you don't lose your cool."
"Fine! Very well! Uchiha Sora! I will make you regret opposing me!" Uchiha Obito snorted in anger, activated Kamui, and vanished once again.
"He's disappeared again! There's no trace of his Chakra nearby!" Ao said, nervously scanning the surroundings.
"He's gone," Uchiha Sora said.
Uchiha Obito had no secrets left before him now, so he naturally wouldn't dare to act rashly.
"Who exactly is that guy? His mask actually has the effect of blocking the Byakugan's inspection; I can't see the face behind it at all!" Ao's expression was grave.
Uchiha Sora shook his head and smiled faintly. "Just a certain member of our Uchiha Clan who is obsessed with his own delusions."
Pausing, he beckoned to Zabuza. "Alright, it's time for us to leave. Everyone, farewell!"
Zabuza nodded and grinned at the Fourth Mizukage and the others. "Fellow villagers, we'll meet again."
The two turned and left.
The Fourth Mizukage called out from behind, "Sir, on behalf of the Hidden Mist Village, I thank you! If you ever need assistance, the Hidden Mist Village will always be at your service!"
...
Two days later.
In a snow-covered Village, Uchiha Sora found Haku on a bridge.
Haku looked very frail, appearing to be only six or seven years old. He was dressed very thinly, shivering in the heavy snow.
Normally, an average person would have frozen to death long ago, yet he had tenaciously survived.
Uchiha Sora walked forward and stood in front of Haku, watching him silently.
Haku seemed to sense someone stopping. He looked up and saw a handsome older brother, momentarily stunned. But he quickly lowered his head in self-deprecation, not daring to look again.
"Lift your head," Uchiha Sora said softly.
Haku was startled, hardly able to believe his ears. Was this older brother talking to him?
He hesitantly raised his head and looked at the older brother again.
At this moment, he felt as if he saw himself in the older brother's eyes.
"Big brother, your eyes are very similar to mine!" he couldn't help but say.
Uchiha Sora was slightly taken aback, then smiled. "How are they similar?"
"Big brother's eyes are just as lonely as mine!" Haku replied.
"Lonely?" Uchiha Sora was stunned again, then shook his head with a chuckle.
Perhaps. As a transmigrator coming to this Naruto World all alone, that in itself was a kind of loneliness.
But Uchiha Sora never felt lonely because he had his own goals and important people by his side.
He reached out and patted Haku's head, smiling. "Since we're the same kind of people, why don't you come with me from now on?"
"W-Why?" Haku asked, looking puzzled.
In this world full of danger, a little beggar like him probably didn't even have the value to be killed. Who would ever need him?
"Because I need you!"
Haku's body trembled, and tears began to flow from his eyes.
