Death: a Pair of Kaleidoscopes at the Beginning

God Itachi, who traveled through time and became the world of Naruto, originally thought he could change the plot and unify the ninja world. However, I still died in the battle with Uchiha Obito. But when I opened my eyes, what appeared in front of me was Rukongai in Soul Society. "Ding! The host awakens the Zanpakutō, and the system is officially activated..." "Ding! The spiritual pressure conversion is completed and the Eternal Kaleidoscope begins to be activated..." At this moment, I finally knew that my system was activated. Moreover, after coming to Soul Society, I discovered that spiritual pressure can actually replace chakra and eye power, and the effect is better than the original. "I, Uchiha Itachi! In this life, I will completely control my own destiny!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
