Naruto: My Ninjutsu Is Powerful by Billions of Points

Ninjutsu is randomly selected! Chakra burns for life! The time traveler Nong Yu comes to the world of Naruto with the "All-In-One Ninjutsu System". Every time he draws a ninjutsu, it is a life and death game - the Nine-Tailed Rasengan may explode, and the powerful fireball technique may backfire! When the Konoha crane held the upgradeable S-level forbidden technique scroll, the Uchiha genius glimpsed the truth of chakra boiling in the eyes of the blood chakra. From Genin to Kage level, he must break through the system's 50% failure rate curse before the Nine-Tails goes berserk and the Akatsuki organization arrives. Extraction failed? Chakra depletion? The medical ninja Liang Yue's Palm Immortal Technique was pressing against his broken meridians. This time, can he rewrite the bloody script of the Naruto world?
