BOC AU: Elder, But Younger Sister

One upon a time, Shen Bu destroyed everything his father had ever worked for. He burned Shen Yu's new home to ashes, consumed his mother's cultivation, and slew the unborn daughter within her. In another time, Shen Yu's daughter was born fourteen years before that event... but Shen Bu's nature did not change. For three hundred years Shen Yu has been searching for something, anything, to save his daughter's life. Crippled by her Elder Brother and stuck in a hidden realm, where time is slowed down to preserve her life. No progress has been made. For three hundred years, Shen Yu has failed to find an answer. One day, feeling the weight of his quest, he returns to the city of his birth to try and drown his sorrows.... and meets a boy that finally gives him hope. ================================= Waking up in the body of an eight year old kid dying of a plague in a Xianxia setting was not my idea of a good time. Where was my cheat?! Where was my system, damn it? My only lucky break was meeting that middle aged old man, whose teaching me how to cultivate. I'm not getting any pills, or some super powerful style or anything, so hes probably nobody important. He does like talking about medical stuff, though. I'm no doctor, but giving him ideas on stuff like organ cloning is probably fine.
