I am from the earth, but I traveled to the Cangyan Continent and became a young master of the Lin family. My father is the head of the family. My mother is not at home now. She is in the Frost Palace in the extremely cold world. She is her palace master. My uncle is my mother's brother and the current emperor of the Liu Dynasty. My grandfather is a general of the Liu Dynasty and holds military power. However, because of my originally weak body, I got a serious illness and died. But, I traveled through time.
