On a planet where technology has lapsed and civilization has regressed to the ancient feudal form, Ling Su, an orphan from a starship who is regarded as a "magician", in order to revenge and survive, meets Ji Yuelan, a sinister princess who is being used as a political bargaining chip and is about to be sent for marriage. On the day of the wedding, Ling Su kidnapped Ji Yuelan, and the two fled from the royal capital. They unearth forgotten starship technology in the wasteland, fight against those in power who regard technology as heresy, uncover the truth about the world (crashed colony ship), and gradually unite all forces. In the end, they repaired the ancient "artifact" (interstellar spacecraft), and in the face of the doomsday crisis of planetary destruction, they led their people to escape from the planet, embark on an interstellar journey to find the origin of human civilization, and confirmed each other's feelings in the vast universe.
