Traveled Through the World of Immortality, but Was Rescued by a Doctor

A car accident caused Gu Fei to accidentally travel to the Tianxuan Immortal Realm. As soon as you open your eyes, it's a story about a hero saving a beauty. Did I save senior sister? Can this still lead to immortality? Do I still have a system? But before he could be happy, he felt his soul being torn apart and heard the voice from the distant blue star: "The patient is dying, but I think he can still be saved." "The right leg is severely squeezed and is ready to be amputated!" Who to rescue? Amputation? Before Gu Fei could react, he saw his senior sister disappear in front of his eyes, and when he opened his eyes again, he found that he was back on Blue Star. Am I back again? Also had his leg amputated? Gu Fei's mood suddenly hit rock bottom, and then a mechanical voice came from his mind: [Ding! The binding of the immortal cultivation auxiliary system is completed. Etc! Has the system followed you? However, if my body is mutilated and Blue Star's spiritual energy is exhausted, how can I use this system to resume my path to immortality and regenerate my broken limbs?
