Sign in as Hokage and Marry Tsunade at the Beginning

Traveling through Naruto, you sign in at the Hokage's office at the beginning, get a fairy body directly, and get Tsunade's favorability level. Tsunade was besieged by debt collectors, and her public proposal shocked the whole village. Konoha's senior officials questioned her strength and arranged an assessment to slap her in the face. I accidentally got a golden finger. The more critical the sign-in location, the more outrageous the reward - I got all the Kage-level Chakra Technique, Susanoo, and Flying Thunder God. Others have been practicing hard for ten years, but he can sign in in one day, crush the Uchiha geniuses, and kill the root assassination team in an instant. Even Danzo can't hold it down. Curing Tsunade's phobia, saving Gaara, and the plan to control spots, all major events in the ninja world were rewritten by him. The five major powers formed an alliance in advance, the Akatsuki organization suffered repeated defeats, and Otsutsuki's invasion was stopped in advance. From Konoha to the ninja world, and then to the cross-universe guardian, he is destined to be the strongest ninja forever.
