Kakashi truly felt that this generation was absurdly strong.
Back in his day, someone like him had already been a genius among geniuses.
The most astounding pinnacle of that era he had witnessed was the Fourth Hokage.
Back then, he had thought the Fourth Hokage was invincible.
But in this era, the Fourth Hokage probably could no longer contend with Sasuke and Neji.

Most importantly, they were both incredibly fast.
They had all mastered space-time ninjutsu.
They could activate it in an instant, and their reaction speeds were ridiculously fast.
The reason the Flying Thunder God Technique was so difficult to learn was that, aside from grasping the core principles of space-time ninjutsu,
it also required exceptionally high reaction speed. After all, the Flying Thunder God Technique could only transport you from one point to another; activating the technique still depended on you.
But if someone subdued you in an instant before you activated the technique, or the moment you arrived at your destination without reacting in time,
then you were practically certain to die.
Because in that instant, you would be controlled before you could even react.
That was also why Tobirama Senju had been instantly subdued by Madara Uchiha during the Fourth Shinobi World War.

Kakashi could feel that clearly.
Even his Mangekyō Sharingan had been taught to him by Sasuke.
Before this, he had still been confident that he could teach Sasuke how to use the Sharingan.
After all, although Sasuke was
