In Konoha, One Can Learn All Ninjutsu in One Second

I'm in Konoha, and I'm starting the graduation exam. Fortunately, I can learn ninjutsu in a second. "Hinata, don't roll your eyes. The teacher will test your clone and substitute skills..." Hinata was shy: "Old, teacher, this, this is my true body." "Ahem~ The teacher knows, can the teacher not know?" "Ding, congratulations on learning the clone and substitute techniques!" Read the sealed book: "Ding, congratulations on learning how to fly the Thunder God, multiple shadow clones, reincarnation in the dirty earth, and mutually multiply the detonating talisman..." "Ding ding ding..." Gradually, Li Ran discovered that ninjutsu was not enough, so: "Eight Gate Dunjia + Bai Hao + Creation Regeneration + Thunder Escape + Immortal Mode + Six Paths + Psychic!" "Grandma Li knock on the door!" "Liu Dehua!" Madara and Kaguya: "I say! This kid is not a human being!" This novel and its characters are purely fictitious.
