Naruto: Waiting for Death at the Beginning, Rejuvenating Each Other?

Kaimon, who died suddenly, traveled through the world of Naruto. He did not become a genius boy and had no bloodline limit. Instead, he became a seventy-two-year-old useless old man of the Uzumaki clan - a ten thousand-year-old genin with depleted chakra and a remaining life span of seventy-two hours. He thought this was God's last malicious joke. Until the red-haired girl cried and threw herself into his arms: "Grandpa Haimen, I don't want to become a monster..." [Ding! The sunset red system is activated! High concentration of emotional intimacy detected - youth value +50! Biological age goes back 7 years! He looked down at Kushina in his arms, then at his fading wrinkles, and fell into deep thought. So... Can wearing stickers make you younger? The closer you are, the younger you are? Can you also unlock the hidden bloodline of the Uzumaki clan? Wait a minute—— Danzo wants to do something in the sealing ceremony? Minato is still a young boy? Is the country of whirlpool about to perish? Sorry, this "dying good-for-nothing old man" doesn't plan to die today. "Sandaime-sama, I have a merciless request - can those girls come and chat with the old man again? Just chat, for the peace of the village."
