After Ren left, Kakashi still stood on the roof of the teaching building and did not leave immediately.
The wind passed by Konoha on the street, blowing his silver hair.
At that moment, he couldn't even capture the trajectory of Ren's departure.
Not Space-Time Ninjutsu.
There are no traces of Kamui being activated, nor are there any Chakra fluctuations caused by the Flying Thunder God mark.
Simply rely on speed.
Kakashi raised his hand and pressed Forehead Protector, who was covering his left eye, and remained silent for a long time.
Over the years, the outside world has said that Kakashi Hatake has become lazy, obsessed with the past, and is unwilling to move forward by guarding that Memorial Stone.
But few people really know him.
The day Obito gave him the Sharingan, Kakashi could no longer stop completely.
He wanted to find out why the crane tail who was always late and always shouted to be Hokage turned into the Obito Uchiha who was hiding in the darkness and promoting countless conspiracies.
He also wanted to ask Obito personally.
How far did Lin's death push all of them.
For this answer, Kakashi practiced hard.
Lightning Release, Swordsmanship, Taijutsu, Ninjutsu.
He took apart everything he had learned from Minato again and again and practiced it again.
Mangekyō Sharingan's Kamui allowed him to see the essence of space.
At first, he could only rely on Kamui to change the space around the target.
Later, he began to try to feel the spatial coordinates, the residue of Chakra, and the invisible connection between the two locations.
Later.
From Kamui, he understood part of the principles of Flying Thunder God Technique.
The Flying Thunder God notes left by Minato have been read countless times by Kakashi.
In the past, he could never understand it.
Why is it that a Kunai with Jutsu Formula attached to it can make Minato jump across distances and appear at any location in an instant?
It wasn't until Kamui continued to evolve and until he truly came into contact with the power of space that he understood.
Flying Thunder God is not just Body Flicker Technique.
That is a movement across space with Jutsu Formula as the coordinates.
Today's Kakashi has long faded away from the Konoha Jonin that only relied on Sharingan to copy Ninjutsu.
His speed, reaction, Swordsmanship and spatial abilities are enough to rival the former Minato Namikaze.
It's just different from Minato.
Kakashi's Flying Thunder God relies more on Kamui's perception of space.
He walked very slowly and very hard.
But every step forward brings you closer to the answer.
Kakashi releases Forehead Protector, revealing the scarlet Mangekyō Sharingan.
"Obito."
"I won't give up."
"One day, I will bring you back."
Uchiha District.
There is a steaming meal on the dining table.
Sasuke held the chopsticks, but his eyes frequently fell on Itachi.
Halfway through dinner, he finally couldn't help but speak.
"Weasel."
Itachi raised his head and asked:
"What's the matter?"
Sasuke frowned and asked:
"Kakashi's left eye, what's going on?"
"That's Mangekyō Sharingan from the Uchiha Clan."
"Why on a foreigner?"
It was quiet at the dinner table.
Fugaku Uchiha put down his chopsticks, and Uchiha Rong also looked at Sasuke.
Sasuke continued to ask:
"Isn't Sharingan the Kekkei Genkai of Uchiha?"
"Ordinary Sharingan are extremely precious, let alone Mangekyō Sharingan."
"Kakashi is neither a member of the Uchiha clan nor Uchiha Bloodline. Why did the family allow him to keep that eye?"
Itachi paused for a moment before responding.
"That eye originally belonged to Obito Uchiha."
Sasuke was slightly startled and asked:
"Obito?"
"Is he the one who belonged to the same team as Kakashi, Minato-sensei, and later betrayed the world of Rogue Ninja?"
"Not bad."
Itachi nodded and said:
"During Third Shinobi World War, Obito was seriously injured during the mission and thought he would not survive."
"At that time, he gave his left eye to Kakashi."
"At first, that eye was just Two-Tomoe Sharingan."
Sasuke's hand holding the chopsticks stopped in mid-air and asked:
"Obito gave it to Kakashi on his own initiative?"
"Yes."
Itachi's tone did not change and continued:
"Obito at that time still regarded Kakashi as a companion."
"He hopes that Kakashi will continue to fight with that eye, and he also hopes that Kakashi can protect Lin for him."
Sasuke said nothing.
It was difficult for him to connect the rumored man who created war, manipulated Akatsuki Organization, and tried to subvert Shinobi World with the boy Itachi said was willing to give his eyes to his companions.
Fugaku picked up the tea cup and said in a low voice:
"Back then, Fourth Hokage Minato Namikaze personally came to Uchiha District."
"He explained the situation to me and interceded for Kakashi."
"That eye was given by Obito, not taken away by Kakashi."
"So, I didn't take it back."
Sasuke looked at his father and asked:
"But later, Kakashi's eyes evolved into Mangekyō Sharingan."
Fugaku tapped his fingers lightly on the table and said:
"This incident is beyond everyone's expectations."
"Sharingan will change with your mood and spirit."
"After Obito's eyes stayed on Kakashi, he followed Kakashi through many battles and endured many stimulations."
"No one thought that it would eventually evolve into Mangekyō Sharingan."
Uchiha Rong sighed and said:
"At that time, there was a lot of opposition within the clan."
"Mangekyō Sharingan is too precious. Many tribesmen have suggested that the eyes should be regained."
Sasuke frowned and asked:
"Why didn't you take it later?"
Fugaku raised his head, his eyes fell on Sasuke, and said:
"Because Ren stopped this."
"Someone in the clan proposed to take back the Mangekyō Sharingan by force."
"Ren objected on the spot."
"He said, Uchiha should not take back what it has given away."
"If Obito hands over the eye to Kakashi, that eye belongs to Kakashi."
"If Uchiha turns around and robs her because her eyes have evolved into Mangekyo, it will only make Shinobi World look down upon. Uchiha doesn't even have the most basic integrity."
Uchiha Rong answered:
"Clan Leader also expressed his attitude later."
"Sharingan can be precious, Mangekyo can also be powerful."
"But the family's reputation and integrity cannot be measured with one eye."
"In the end, the family did not take back the eye, but added Sealing to Sharingan."
Sasuke asked:
"Is this the Sealing that Sakura said?"
"Yes."
Itachi nodded.
"If someone tries to take out that eye by force, Sealing will explode."
"This is the honor of protecting both Kakashi and Uchiha."
Sasuke nodded.
He was still a little concerned about Kakashi's eyes, but after hearing the story, his rejection was much less.
That is not the power Kakashi stole from Uchiha.
That is the relic left by Obito to his companions.
Fugaku looked at Sasuke, softened his tone, and said:
"Team 7's class placement has been determined?"
"OK."
Sasuke replied:
"Naruto, Sakura, and me."
"The teacher who leads the team daily is Kakashi Hatake."
