Asking for Immortality

When the protagonist no longer has the opportunity to change his destiny, how should he move forward in the cruel world of immortality? When he is no longer an invincible genius, he can only face the cruel truth on the road to immortality - can he still be called the "protagonist"? When he went through many difficulties and dangers and struggled all his life, but still could not reach the top of the world, where should he go? There is no aura of the destiny-destined protagonist here. He is not a loser, nor does he have any heaven-defying qualifications - he just has three spiritual roots. But on this road of cultivating immortality, he blazed his own path. Ordinary and extraordinary. He will become the ancestor of the line. He is "I" in another world. ——The entire text is narrated in the first person.
