Imagine waking up to find your life reset, not to square one, but to a childhood you thought existed only within the confines of a virtual world. In Dig Up the Sun Emperor's Legacy: I Build an Invincible Undead Legion, Carlos Valois gets that jarring second chance. He's back in "The Dark Era," a land he once conquered as a gamer, now facing it for real, as the last scion of a doomed noble house. A grim prophecy hangs over his head: betrayal and death await him at the hands of someone he once considered a friend. But Carlos holds a trump card: his memories of the future. While other children play, he embarks on a daring quest, leveraging his future knowledge to seize divine legacies. He brazenly steals a Demigod Mark from the ancient Sacred Oak, a power that should have remained hidden for years. By fifteen, Carlos awakens as a Death Herald, but he's no ordinary necromancer. He's a force of nature, blending necromancy with his stolen divine powers to forge a unique path. Forget the frail, spell-casting wizards of old; Carlos is building an army of unstoppable undead warriors, each one meticulously crafted through secret evolution paths. These aren't mere cannon fodder; they are elite soldiers, ready to dominate the battlefield. Every encounter is a calculated risk, every "coincidence" a step closer to unimaginable power. As his sister marvels at his apparent good fortune, Carlos systematically loots the world's hidden treasures, techniques, and legacies. Will Carlos defy destiny and ascend to become the supreme Death Herald, or will the weight of prophecy crush him? Dive into this thrilling tale of second chances, strategic brilliance, and the rise of an invincible undead legion.
