The central theme of this book is "holding fast amid betrayal, growing through revenge." The protagonist, Haotian, survives the calamity that destroys his clan and endures the darkest depths of human life. Yet on his path of revenge, he constantly questions his own heart: when he holds the blade of slaughter in his hands, how is he any different from the enemies who massacred the human race back then? In the end, whether in the mortal world or the immortal realm, he must find his own "Way of the Human Emperor" between power and conviction, ruthlessness and tenderness.
