My Iron Cloth Became Indestructible

He woke up in a mass grave, poisoned and dying, just another corpse in the infamous Five Poisons Cult. His predecessor was murdered, used as a human sacrifice for vile experiments. This wasn't the heroic transmigration he dreamed of; it was a death sentence. But just as despair set in, a game-like System materialized! His first mission: Survive. His only power: a seemingly useless 'Iron Cloth' skill. Yet, with every terrifying day endured, EXP poured in, transforming his frail body. Iron Cloth wasn't just a basic skill; it was a path to an unbreakable physique! Now, with muscles bulging and skin tougher than steel, Chen Xuan is no longer the cult's prey. The arrogant Senior Brother who condemned him? The monstrous 'Azure Baby' haunting the shadows? Let them all come. Survival was just the beginning. His system demands blood.
