Traveling to Another World to Cultivate Immortality

[Travel to Another World] + [System] + [Cultivation Through the Fetus] + [Fantasy] [Mine Warning: Not a thrilling story, with a slowly developing protagonist, a strong female lead, and no CP.] Sujana was in a car accident, but because she was bound to the system, she traveled to another world and became an unborn fetus. While still in the fetal stage, she began practicing techniques to absorb innate energy. Just when she thought her special physique would give her a head start, she was born prematurely, which thwarted her efforts and significantly reduced her special physique. As she aged and gained more cultivation, she discovered that this other world was vastly different from what the system had described. It was a world rife with beasts, and the cultivation methods were crude, far inferior to those given by the system. Shortly after Sujana began her cultivation, the system went dormant for unknown reasons, leaving her alone in this other world. As her cultivation level increased, Sujana discovered that the entire world was a vast mystery, and she was at the very bottom of it. Only by reaching the highest point could she see the truth. Will she finally discover the truth about the world?
