The world is divided into five realms: the Human, Divine, Nether, Demon, and Monster realms. The protagonist is a princess of the Nether Clan, but she has been frail and sickly since childhood, weaker even than an ordinary mortal. For the sake of survival and other goals, elite members of several clans are brought together by a twist of fate to seek the Holy Sky Wings, a treasure left behind by the Creator God, and grow stronger along the way.
The story is primarily a mystery, with romance playing a smaller role.
