The peace-loving Gloris Empire — whose power is widespread— made enemies with an unknown ancient beast specie called Shadow Prisoners, a bipedal sentient beast species whose growth is increasing in an exuberant manner. They lived away from humans. Their forms are still unknown and their powers remained unexplained. On the other hand, a young man named James — whose last name is not specified — died a tragic death and later on got transported into another dimension, like the usual cultivation novels, Isekai, and such.
