Descendants Repay Their Ancestors: I Build the Supreme Immortal Clan

In a freezing cell at the edge of despair, he stands alone, with only his bloodline as the key to building a stairway to the heavens. From humble beginnings to the throne, he uses his family tree as a blueprint and his descendants as a foundation, carving out a sanctuary in this mortal world, beyond the reach of Heaven's laws. With no equal left among mortals, he turns his gaze beyond the nine heavens. The beings who once looked down upon all living things will eventually discover that the world they treated as a chessboard has long since changed hands. Tell me, can the starry seas of the heavens contain this... Emperor of the Mortal World?
