Shin Uchiha naturally knew how difficult it was to reach the third stage of Lightning Release Armor. In all of Kumogakure, only the Third and Fourth Raikages had managed it.
If Shin Uchiha had not possessed a practically cheating Mangekyō dōjutsu that let him copy it directly from the Raikage, there was no telling how long it would have taken him to master it.
Tsunade, for example, had only trained her Lightning Release Armor to the second stage. Although having a child had played a part in that, it still showed how difficult the training was.
Shin Uchiha waved a hand, signaling for him to put away his Lightning Release Armor, then continued:
"After what happened, your Sharingan should have reached the third tomoe, right?"
As soon as Shin finished speaking, Sasuke activated his Sharingan. But once he did, his eyes filled with pain and inner turmoil, and even his expression became full of malice and hatred. Clearly, activating his Sharingan had brought back painful memories.
Before Shin Uchiha could speak, Sasuke spoke first, his voice hoarse and self-mocking:
"That man was right. The power of our Uchiha Clan represents bloodshed and ill fortune. The more pain and turmoil we experience, the stronger it becomes."
Shin Uchiha shook his head helplessly at Sasuke's words, then casually rapped him on the head. The sudden pain snapped Sasuke out of his negative emotions, and he looked at his master in confusion.
After bringing Sasuke back to his senses, Shin continued:
"Actually, Itachi wasn't entirely wrong. The Uchiha Clan's Sharingan does evolve through its owner's intense emotional ups and downs.
"But he got the cause wrong. The Sharingan can only evolve as your spiritual power increases, and intense emotional ups and downs are merely one way to increase that power."
