A feared assassin from the 1950s known only as Arthur dies during a mission beneath the frozen rivers of Siberia—only to awaken in the frail body of Han Lei, a starving orphan boy in the distant past of a mystical empire. Han Lei perished after consuming a forbidden pill of immense power, but something went wrong—and through his death, Arthur''''s soul was pulled into a world of cultivation, martial sects, immortality, and divine warfare.
