I Have No Intention of Becoming an Immortal, I Just Want to Protect You from Worries

Who talks about eternity? In this era when the road to immortality is cut off, who dares to claim to be invincible? The involvement of cause and effect, the battles again and again, just to embark on the road to immortality, the reincarnation again and again, the protection again and again, I am tired of it, I don't want to become an immortal, I just want to stay in the mortal world forever to keep you worry-free!
