Every Heir Gets a Combat Skill, Mine Only Said YES or NO, So They Exiled the Son Who'd Destroy Them

They handed me a single silver coin and told me I was no longer family. My younger brother had just awakened "Sword Saint" — the kind of skill that gets you statues and songs. Me? At fifteen I'd awakened a skill that did exactly one thing. It answered yes, or no. Nothing else. My father called it a scam. He didn't care that for three years that "useless" skill had quietly raised our house's fortune by more than forty percent, kept our people fed, and seen storms before they hit. The day the sword arrived, none of that mattered. I was given one coin, forbidden the family name, and put on a road out of the country — with orders, I would soon learn, to make sure I never reached the end of it. What none of them understood — what my father will spend the rest of his life regretting — is that a skill that only answers yes or no, asked the right way, can see everything. Every price before it moves. Every blade before it falls. Every road, every trap, every lie. They threw away an oracle and called it garbage. So I built. A handful of coins became a fortune. A fortune became a name in a foreign empire. When a monster no sword could stop tore through a city, I didn't fight it — I out-thought it, and brought a cathedral bell down on its skull. That bought me a place no one else wanted: a death-fortress where nine in ten soldiers never last a year. I turned it into a fortress that never lost a man, and I gathered the people everyone else had discarded — a mage who believed he was worthless, a swordswoman who chose me when my own blood never would. Then the war came. And under the enemy banners, on the far hill, flew the crest of the family that had thrown me away. They never saw my face. They only felt the hand that took their armies apart — the ghost strategist who seemed to read fate itself — and they had no idea he was the son they'd exiled for a single coin. That was only the first installment of what I intended to collect. But the deadliest enemy I would ever face wasn't a monster, and it wasn't an army. It was a man. A duke who moved through shadows and decoys, who had learned the one way to blind someone who can see the future: never decide anything until the last possible second. Against him, for the first time in my life, my skill went dark. And as his knives closed in, the ruined remnants of my old family came crawling to the famous strategist's gate — begging for protection from the very shadow that was hunting me, still blind to who I truly was. This is the story of a thrown-away son with a "useless" skill, a family that learned far too late what they had given up, and the day they finally looked up… and saw the boy they had once handed a single coin. Yes, or no?
