Contract of Races: I Get Stronger Through Bonding

Ethan Cole died at his desk at 2 AM. His last thought was about a load-bearing calculation. His first thought in the new world was about the tensile strength of the chains on his wrists. Thrown into the Abyss as a human sacrifice, he activated the Myriad Bonds System — a power that makes him stronger every time he forms an intimate Bond with a woman of a different race. His first Bond? A Dark Elf princess chained in the darkness for three years. His first kill? A shadow monster taken down by collapsing a ceiling on it. His first thought after both? "I need to build a city." Armed with shadow powers, a brain full of civil engineering, and 3,000 hours of Civilization VI experience, Ethan doesn't just survive — he BUILDS. A camp becomes a village. A village becomes a walled city with aqueducts, forges, and the only cross-racial marketplace on the continent. Every new Bond brings a new skill tree, a new race to his kingdom, and a new faction that wants him dead. The Human Empire calls him a traitor. The Elven Council calls him dangerous. The Dragon Court calls him irrelevant. They're all wrong. Ten races. Ten women. Ten skill trees. One kingdom that shouldn't exist. And enemies everywhere who want to make sure it doesn't.
