My Years as a Ghost in the Cultivation World

After Tan Xin dies suddenly in the 21st century, she transmigrates into the cultivation world, only to be killed immediately. A thousand years later, in the form of a disembodied soul, she takes Su Lingfeng, a girl destined by fate, as her disciple. From there begins the pair's daily life in the cultivation world. After years spent making her way through the cultivation world, Tan Xin rebuilds her body. She and Su Lingfeng ascend together to the Immortal Realm, where they embark on another epic life... Two female leads, with a normal teacher-disciple bond! No romance for either!
