I, Yu Uchiha, am devoted to cultivating immortality

The world of Naruto is a hopeless world. Even the protagonist is a chess piece that has nothing to do with victory or defeat, let alone ordinary time travellers.
Uchiha Yuu just wanted to eat something good, drink something good, and watch the sunset and moonrise with the kitten.
By the way, become an immortal and beat the chess players to death.
I'm not bothering you, so why are you having trouble with me?

Uchiha Yuu does not practice magic, he practices Taoism and nature.
What is Tao following nature?
Yuu's answer is simple: suck in the natural energy, it will hurt and it will feel good.
