My Wives Made Me Invincible

Leo Miller is a 49-year-old veteran stuck on the border, where castle lords keep throwing soldiers into battle. The Love-Oath System gives him a blunt status: one hundred seventy-six days left, combat power one, old wounds still killing him. He is broke, covered in liver spots, and the system feels less like a mission than a death sentence.

When Barnaby mentions the border cavalry selling demi-human slaves, Leo sees a loophole. The system says sacred oath, not pure human. He grabs Barnaby, borrows every coin he can, and his plan is blunt: “I'm marrying demi-humans, as many as I can.”

At the auction, three sisters cost nine gold. Leo pays. Centurion Cane wants the fox girl and warns that demi-humans are demons in human skin. Leo does not flinch. He walks out with all three—a wolf, a fox, and a bird, same mother, different fathers.

At home, the sisters brace for beatings and refuse to sit at the table. Leo pulls them up and makes them eat like family. He tells them they will be his wives. The fear does not disappear, but for the first time they sit at a table.

One of them stays with him that night. The system reacts: soul resonance detected, lifespan increased, first bloodline union complete. Combat power rises to five. Leo wakes younger and stronger, no longer just waiting to die.

But the frontier has more waiting. General Lila is still in danger, and the empire has a plot that will not stop for one resurrected old soldier. The sisters are only the beginning.
