Akihara Kagura spoke quite accurately.
Once Uchiha Sasuke finds he cannot gain the power for revenge within Konoha, he will certainly look beyond. If someone beckons him and tells him he can obtain the power for revenge, he would immediately defect from Konoha and go there.
For example...
Now Uchiha Sasuke cannot get power from Kakashi Hatake, but from Akihara Kagura he can, and he is eager to leave Kakashi Hatake's side and join the Root.
When Kakashi Hatake and Akihara Kagura left the training ground, Uchiha Sasuke watched their backs with a firm look in his eyes: "I must join Akihara Kagura's Root. Uchiha Itachi became stronger when he was in the Root!"
"Sasuke-kun..."
Haruno Sakura looked at Uchiha Sasuke with some worry.
"Sakura, don't tell Kakashi-sensei."
Uchiha Sasuke glanced at Sakura, raised his hand and threw a shuriken, speaking in a deep voice: "Kakashi-sensei is always refusing my revenge... only by joining Akihara Kagura's Root, without Kakashi-sensei's obstruction, can I obtain stronger power!"
"Okay..."
Haruno Sakura could only nod and agree.
Night.
Ichiraku Ramen.
Kakashi Hatake and Akihara Kagura returned separately after having dinner.
As Akihara Kagura casually walked toward the Root base, a figure suddenly flashed out and knelt on one knee in front of Akihara Kagura, looking at Akihara Kagura with a determined expression: "I want to join the Root, to gain the power for revenge against Uchiha Itachi, please help me Kagura-sama..."
It was Uchiha Sasuke.
The little fellow couldn't resist jumping out.
Because Uchiha Sasuke thought Akihara Kagura was in favor of him joining the Root, only not agreeing due to the face of Kakashi Hatake, so he secretly came into contact with Akihara Kagura.
"..."
Akihara Kagura looked at Uchiha Sasuke.
Back then, Uchiha Itachi joined the Root for the so-called salvation of the Uchiha Clan, kneeling in front of the previous generation Root Leader Shimura Danzo.
Now, Uchiha Sasuke is kneeling in front of him, the current Root Leader, to kill Uchiha Itachi and avenge the Uchiha Clan.
"Fate is really interesting..."
Akihara Kagura sighed, his gaze resting on Uchiha Sasuke: "Unfortunately, Captain Kakashi does not agree with me doing this..."
"..."
Uchiha Sasuke's eyes suddenly dulled.
"Don't think of the Root as so glorious; the Root is more brutal than you imagine..."
Akihara Kagura watched Uchiha Sasuke and continued softly: "Once a member of the Root violates orders or reveals their identity on their own, they will immediately face death. Back then, Uchiha Itachi was honed in such a harsh environment and thus grew stronger..."
"I can do it too!"
Uchiha Sasuke's eyes immediately turned very cold!
Akihara Kagura nodded satisfactorily, continuing: "If you are determined to join the Root, you can only become a secret intelligence member and cannot reveal the identity of the Root to anyone, hidden in the dark with your secret..."
"As a member of the Root, the missions you will execute are all the most dangerous ones. I will randomly assign you some dangerous missions, even some like assassination missions against S-Class Traitorous Ninjas like Orochimaru. Do you really think you can do it?"
"..."
Uchiha Sasuke's forehead showed a drop of cold sweat.
Because during the Chunin exams, Uchiha Sasuke had indeed personally encountered Orochimaru, deeply aware of Orochimaru's terrifying nature. Does he really have the ability to complete the mission to kill him?
"Just a casual mention."
Akihara Kagura looked at Uchiha Sasuke and continued softly: "According to the intelligence I have, Orochimaru was once defeated by Uchiha Itachi. If you want to defeat Uchiha Itachi in the future, at the very least, you need to have the ability to kill Orochimaru..."
"I can!"
Uchiha Sasuke immediately felt a surge of fighting spirit!
Even though the fear Orochimaru brought to Uchiha Sasuke was profound, it could not compare to his hatred for Uchiha Itachi!
Moreover...
If he can't even kill Orochimaru, who is a defeated subordinate of Uchiha Itachi, how can he talk about killing Uchiha Itachi!
"Then go back first."
Akihara Kagura walked toward the direction of the Root base without turning back: "The Jutsu I taught you, practice well. From today onwards, you are a secret member of the Root."
