The Oldest Veteran in the Ninja World: From the Sage of Six Paths to Boruto

"How many years have you been in the ninja world? I've existed since the Sage of Six Paths established the Ninja Sect!" I was there when they fought Kaguya, I was there when the Sage built the Ninja Sect, and I was still there during the battle between Indra and Ashura... Through the vicissitudes of time, I sit and watch the conflicts of the ninja world. Though I never act, my legend is everywhere in the ninja world. Time is a knife that cuts down the proud, but I dare to compete with time! I am the one who knows everything in the ninja world, the true immortal! ------ "Let me see your age in the ninja world." "Oh? Already a hundred years old? That really surprised me!" "Let me give you a reference number so you know how strong the veteran you're facing is..." "My age in the ninja world is... 5000 years!!!"
