Konoha: My Ninjutsu Has No Upper Limit

[Konoha's strongest cannon fodder + D-level ninjutsu to kill the god + proficiency panel + unlimited growth + combination skills] "Who said D-level ninjutsu is rubbish? I, the border cannon fodder, awakened [Proficiency Panel] at the beginning, and there is no upper limit for ninjutsu!" "When [Clone Technique] is practiced to MAX, it becomes an entity comparable to a shadow clone, and it can also self-destruct! Substitute TechniquePractice to MAX, it is an instant magical skill that ignores locks! High FireballPractice to MAX and become Amaterasu who burns mountains and cooks seas! A few years later, when Uchiha Madara watched me destroy his complete Susanoo with the basic three-kaya technique, he began to doubt life. Don't talk to me about the limits of blood inheritance. In the face of absolute proficiency, all geniuses are paper tigers! "
