Mortal Girl Cultivating Immortality: Going Against Destiny and Going to Immortality

[Mortal female cultivating immortality + growth of the heroine + no system + single male protagonist + unclear emotional line (beware of the surprise)] Su Yi, a body with minimal spiritual roots, was involved in a cultivation killing situation because of an immortal bone. She was stained with blood from the cold pool, stepped into the path of chaos and immortality, shattered the seals of the Three Emperors on her own, and reaffirmed her true heart. When the devouring world comes and all the souls are sacrificed, she stands side by side with the fire-bearer who has burned away reincarnation, ignites the light of the new sky with mortal bones, cuts the sky with her sword, and together proves the immortal return.
