Loyal family annihilated overnight! Acheron Cross, former genius of the First General's Manor, had powers sealed for five years, playing the fool to preserve his family. At the funeral, his seven fiancées broke off engagements. Family destroyed, home gone. Became a Terrestrial Immortal! No system, decisive slaughter without a saintly heart. Enemies will kneel! “Annihilate my entire clan? Then it's only fair I annihilate your royal family, isn't it?” God of slaughter returned, reckoning begins!
