Naruto: Kakashi's Infinite Chakra

[Hokage fan fiction + unlimited chakra + dual Kamui + ruthless + rewriting tragedies + invincible protagonist] Chen Zhe had just become Kakashi when he faced the most deadly choice: Obito was about to “die,” Rin was surrounded by Stone ninjas, and Madara Uchiha’s pawn was already hiding in the shadows. Knowing the future, he understood all too well that if he took only the left eye, Madara would rescue Obito, Rin would die, Minato would die, and the Nine-Tails’ rampage and the Fourth Shinobi World War would follow one after another. So Chen Zhe reached out a second time. With both eyes in hand, his perfect Sage Body activated! Vast amounts of chakra nourished his Mangekyo Sharingan. Kamui intangibility was no longer limited by time, and he no longer had to carefully ration his space-time warps. Others were exhausted after using a forbidden technique once. He could spread Kamui across the entire battlefield. Others risked death transplanting Hashirama Cells. He could use them to awaken Wood Release. From Kannabi Bridge to Madara Uchiha’s underground base, from Orochimaru’s lab to the Five Kage Summit, the Kakashi who had to calculate his chakra in battle was gone. In his place stood a spatial god of slaughter with a chakra bar that seemed to have no end!
