When the mystery of Xu Taichu's life experience is revealed, the undead army invades the territory, his father is brutally murdered, ancient existences compete and devour each other, the struggle between aristocratic families and imperial power, and the madness and reason hidden in the depths of human nature will be completely intensified.
