After a long silence, Kakashi said softly, "There is no need to make Yeyu your goal. He is different from everyone else."
Sakura nodded. "I know. His strength is so inhuman that I think it would be difficult to even use him as a benchmark."
Kakashi gave a wry smile. "Actually, his power today shocked me as well. It was the first time I realized he possessed such immense strength."
"He had never shown himself to be that strong before."
"In that regard, I am the same as you. I only learned of his true power today."
Sakura smiled. "No wonder he was promoted to Chunin right after graduation and even became the Hokage Assistant."
"I couldn't quite understand it before, but now I fully grasp it. Yeyu becoming a Chunin was only temporary; it won't be long before he is promoted to Jonin."
Kakashi looked up at the ceiling and sighed. "I suspect that once he completes this mission, he will be promoted to Jonin upon his return. There has never been anyone who was promoted to Jonin after just a single mission."
"Perhaps Yeyu will be that person. He is always so different."
"He always does things that are beyond expectation."
Sakura looked at Sasuke, who was lying nearby in a coma, and said with a pained heart, "Kakashi-sensei, Sasuke has made Yeyu his goal. Can he really catch up to him?"
Sasuke had fallen unconscious before Yeyu appeared.
He did not know the extent of Yeyu's strength.
He did not know he was chasing a goal he could never reach; it was too desperate.
Kakashi fell silent again.
Previously, although he felt it was unlikely for Sasuke to catch up to Yeyu, he believed that as long as he worked hard enough—
With the bloodline of the Uchiha Clan and his natural talent, it might not be impossible to get close to Yeyu.
Just as the Third Hokage had planned, Sasuke and Naruto were meant to be Yeyu's right and left hands in the future.
But now, it seemed that Sasuke catching up to Yeyu was a long shot.
Even getting close to him would be difficult.
Yeyu was only twelve years old and already this strong—strong to the point of being a monster.
One could only imagine how terrifying he would be at his peak.
Twelve was definitely not the stage where a ninja was at their strongest.
The peak age for a ninja was between twenty and fifty.
Kakashi didn't say it aloud, but he thought to himself, "I fear that even if Sasuke awakens those legendary eyes, it will be hard to catch up to Yeyu."
He could blast away a Tailed Beast Bomb with physical strength alone.
Even a Susanoo could likely be shattered by his raw physical power.
Kakashi had actually already awakened the Mangekyou Sharingan, but with his current strength, he was unable to use it.
However, Kakashi knew that the Sharingan could manifest the Susanoo.
He had learned this while researching records of the First Hokage.
Given Yeyu's display of physical prowess just now, shattering a Susanoo didn't seem like much of a problem.
Although Kakashi had never seen a Susanoo, his estimation was likely accurate.
Tsunade could shatter the skeletal form of a Susanoo using her super strength.
Yeyu's power was far beyond Tsunade's, so shattering the skeletal form of a Susanoo would be effortless.
It was just unclear whether his power could shatter a complete-body Susanoo.
Yeyu had not had the chance to try.
After all, although Yeyu had inherited all of Akainu's power, due to his unique nature and the fact that he was in the ninja world, his performance was actually several times stronger than Akainu's original power.
The physical strength of Akainu in the Pirate World was not as absurd as Yeyu's, where a single punch could cause thousands of meters of destruction.
Without relying on Devil Fruit abilities, the area of destruction from a single punch was only a few dozen meters; only by using his fruit abilities could he reach several kilometers.
But Yeyu, using only his fists combined with Armament Haki, destroyed an area of several kilometers.
The power had increased by more than tenfold.
Perhaps it was because the worlds were different, perhaps because Yeyu's constitution was special, or perhaps because Akainu's power mutated when it merged with his own.
Yeyu's power was indeed several times stronger than Akainu's.
Before inheriting Akainu's power, his talent had been very poor.
Even with great effort, he could only reach the level of an average ninja.
Yet after obtaining Akainu's power, he was able to unleash it to a degree far exceeding his own limits.
Sakura looked at Sasuke and said softly, "I don't know if it's a good thing or a bad thing that Sasuke is unconscious and didn't see the battle between Yeyu and Naruto."
"It's not just Yeyu; even Naruto hides such immense power within him."
Although Yeyu had completely dominated Naruto during their fight earlier—
Naruto's power was also incredibly terrifying; even Kakashi, a Jonin, would not be a match for him in a single exchange.
Can Sasuke really catch up to that power inside Naruto?
With two peers so far ahead of him in strength, what kind of state of mind must Sasuke be in?
Sakura grew increasingly worried. "Kakashi, can we avoid telling Sasuke about Naruto? I'm afraid he won't be able to handle it."
Kakashi looked at Sakura and sighed, "It seems you really do love Sasuke, considering things to this extent for him."
"But he will find out sooner or later. When that time comes, he will be even more devastated. After working so hard for so long, to suddenly be told that Naruto's strength is so much greater than his..."
"He won't be able to take it."
Sakura fell silent.
"Kakashi, doesn't Sasuke have any power within him that can compare to Yeyu and Naruto?"
"He is from the Uchiha clan; surely he must have some extraordinary Kekkei Genkai, right?"
Sakura didn't hope for Sasuke to be powerful just because she liked him; she was worried that if the gap between Sasuke and the likes of Naruto and Yeyu became too wide, his mentality would collapse.
She truly loved Sasuke from the bottom of her heart.
She had liked him ever since the first time she saw him.
Unlike Ino, who was purely attracted to Sasuke's looks, Sakura loved Sasuke for who he was.
Kakashi looked at Sasuke, unsure whether he should disclose information about him to Sakura.
He raised his head, met Sakura's earnest gaze, and sighed. "You're right, Sasuke is of the Uchiha clan."
"The Uchiha clan can awaken a Kekkei Genkai known as the Sharingan."
Of course, Sakura knew this.
"The highest level of a standard Sharingan is the Three-Tomoe Sharingan; this Sharingan of mine is a Three-Tomoe Sharingan."
"It was transplanted to me by a friend from the Uchiha clan."
"And above the Three-Tomoe Sharingan, there exists a legendary eye."
"It is called the Mangekyou Sharingan."
"It is a pair of powerful eyes capable of controlling even a mighty beast like the Nine-Tails."
"However, the difficulty of awakening these eyes is immense; even within the Uchiha clan, it is extremely rare."
"Furthermore, if these eyes are overused, there is a risk of going blind."
Kakashi knew that excessive use of the Mangekyou Sharingan would lead to a decline in vision, and eventually, blindness.
He knew this from when he later encountered Itachi Uchiha and heard him mention the extent to which his own vision had deteriorated.
Moreover, using the abilities of the Mangekyou Sharingan requires an immense amount of chakra.
If one's chakra is insufficient and they force its use, it will excessively drain the body's chakra, which can be fatal in severe cases.
Itachi Uchiha was someone whose chakra reserves were limited; because he overused the Mangekyou Sharingan, he was constantly draining his body's chakra.
His reserves were only at the level of an average Jonin; his strength lay in his combat intelligence and the techniques of his Sharingan, not in his chakra volume.
Frequent use of the Mangekyou Sharingan led to constant physical depletion, until eventually, both his eyes and his body could no longer hold out.
Unless one is like Obito Uchiha, who transplanted the cells of Hashirama Senju to provide the massive chakra support needed to ensure the Mangekyou Sharingan's vision does not decline and the body remains unaffected.
