Glenn Hughes had spent most of his life confined to a hospital bed. Brilliant yet shackled by a cruel fate, he endured ten long years under the relentless weight of an unforgiving disease. Between medications, surgeries, and agonizing treatments, death had begun to seem less like an end and more like a mercy.But when he finally closed his eyes for the last time… rest did not come.The stench of sweat, dust, and blood was the first thing to greet him. Shackled, filthy, and drained of strength, his body was no longer his own. He was no longer in a hospital but in a cell. No longer a patient, but a prisoner.“What the… what the hell is this?”Glenn had been thrust into a world of steel and prana, reborn in the body of a condemned slave. Once a noble, now nothing more than a number among the damned.Yet, something was different. There was a reason he was still alive.Witness Glenn’s transformation as he is dragged through agony and ecstasy, suffering and desire, boundless pleasure and unrelenting torment—all while shouldering a burden so crushing that any other man would break.------------------------------------------------------------------------No netorare (NTR), no system, no incest, no consanguineous relationships.
