Blue Core

“A reincarnated soul awakens as a sapient sapphire Dungeon Core, rejecting brutal slaughter to engineer an enlightened subterranean sanctuary.”

Reincarnated into a strange fantasy world not as a human hero or demonic beast, but as an immobile sentient crystalline Dungeon Core. Unlike the brutal Red Cores that enslave and torture mortals for despotic mage-kings, or the monstrous Great Dungeons lurking beneath ancient mountain roots, this newly awakened Core refuses the bloodthirsty cycle. Guided by modern logic, engineering principles, and a deep desire for peaceful coexistence, the Blue Core crafts ingenious defensive labyrinths, magical waterworks, and protective sanctuaries. An epic 256-chapter adventure with over 21 million views on Royal Road.
