Even with a third of its power canceled out, Tsukuyomi still left Kakashi in almost unbearable agony.
In the Genjutsu world where Uchiha Itachi completely controlled time, space, and mass, Kakashi was stabbed repeatedly with a tachi by Uchiha Itachi for two days!
In other words, if Lin Guang had not canceled out that portion of Tsukuyomi's power, Kakashi would have been stabbed for three days.
Because Uchiha Itachi controlled the Tsukuyomi Space, Kakashi's pain was also amplified infinitely.
Even Ibiki Morino could not inflict torture like this. He could not stab someone continuously for two or three days while ensuring they stayed alive.
When Kakashi finally endured the duration of Tsukuyomi and his consciousness returned to reality, only an instant had passed!
The pain Kakashi suffered in the Tsukuyomi Space was the same as in reality, and it nearly caused his mind to collapse!
This was one of the abilities of Uchiha Itachi's Mangekyō Sharingan, Genjutsu: Tsukuyomi!
The moment he returned to reality, Kakashi dropped to his knees on the water.
"So there really is someone..."
In fact, Uchiha Itachi had already noticed something different when he looked around earlier.
He simply had not activated his Mangekyō Sharingan's abilities, so he could not see it.
Now, although Uchiha Itachi's Sharingan still appeared normal, its abilities were already those of the Mangekyō.
Through his Sharingan, Uchiha Itachi roughly determined Lin Guang's location.
But Uchiha Itachi did not dare act rashly for the moment. Activating Tsukuyomi just now had consumed a great deal of his dōjutsu power.
The person hiding in the Small Grove clearly also possessed the Sharingan, and not an ordinary Sharingan, but a Mangekyō Sharingan like his.
*Was it Sasuke... no, it couldn't be Sasuke. Or were there other Uchiha in this world besides that man and us
