Become a True Immortal from Paramecium

I am a grasshopper, and I have no intention of becoming a fairy—— The world is vast, and all races are vying for supremacy. The human race refines their energy, builds their internal organs, and focuses on ancient magic and immortal cultivation; the demon race's flesh and blood mutates and evolves, and uses their bodies to shake magic to achieve all kinds of physical ways; the secret race patrols the sky, and its form and spirit are transcendent and will never be eradicated... And me! A paramecium cannot survive more than three breaths. It seems to have nothing to do with this, right? Even if it involves wisdom development, evolution, species selection, practice, cultivation... Etc.: "There has never been a paramecium in immortality who has become a true immortal of all kinds. Maybe I can fill this gap."
