The main character of the Cultivation novel " My Dantian Has Taotie " was Chen Fan. He had the ability to devour and could get the help of the Divine Beast Taotie to open the path of invincibility. Although there wasn't a woman named Ghost Empress, in the cultivation novel " Dao Cultivation ", the protagonist started off as a robot. Later on, he could devour the tiger demon soul, refine the dragon body, and finally become a human with super immortal cultivation abilities. In addition, in the urban novel " Carry a Spiritual Field with You ", the main character also had a younger sister. I hope you like my recommendation.
