Naruto: Signing in from Kanna Kunqiao

Ryuun Uehara traveled through the world of Naruto and signed in from Kanna Kunqiao. The reward: the top immortal body, the ultimate chakra, and the ability to recover the body. From then on, a series of sign-in tasks started: Mizukage's office, the roots, the top of the Nine-Tails' head, the rain ninja Murakusa, in front of the Ten-Tails... What the system gave him were god-level rewards that shocked the ninja world! Ultimate Chakra, Wood Release, Flying Thunder God, Mangekyo Sharingan, Samsara Eye... Senju Hashirama: "There is no doubt that Ryuun Uehara has surpassed me and become the strongest Hokage in the ninja world!" Sarutobi Hiruzen: "He is the most talented ninja I have ever seen, surpassing Namikaze Minato, the Sannin, and even the First Lord!" Uchiha Madara: "You actually have stronger power than me, then let me see! What can you do?" This novel and its characters are purely fictitious.
