The Exiled Sovereign: Relentless Grind

On Earth, he was a high-level Human Resources Minister who controlled corporate empires through talent optimization, labor audits, and tracking insider threats. But when he chose honesty over survival, the corrupt elite had him executed.

Reborn into a high-fantasy world where raw magical power dictates leadership, he is Karl—the "worthless" third prince. Born with a completely locked and atrophied mana core, his royal brothers deem him an invalid and exile him to Oakhaven, a starving, ruined frontier territory meant to be his grave.

But they forgot one thing: Karl isn't a naive politician anymore. He is a deeply cautious, calculating master of psychological profiling.

Lacking magic, Karl treats his own body like a failing corporation, using modern sports science, biomechanics, and brutal physical grinding to forge a hyper-efficient martial foundation in secret. Armed with [Talent Audit]—a system skill that lets him see the professional profiles and true loyalty metrics of everyone around him—he begins a cold, corporate-style restructuring of his exile.

He doesn't need an army to build a nation. He just needs to put the right people in the right places, out-scheme the local criminal syndicates, and turn his enemies' own spies into double agents.

The conspiracy runs deep, the winter is coming, and his family wants him dead. But a visible saint is just a target. To survive, the invalid prince will become the ultimate underground puppet master
