El herrero mudo es el Señor Dragón

Once a supreme Dragon Emperor, Lion reincarnated as a mute, powerless blacksmith to escape war. But when a traitor sells out his family and an enemy armada surrounds them, brutalizing his loved ones, the mute finally speaks. With a single word in the Dragon Tongue, ten thousand dragons bow. Summoning a mythical beast that vaporizes armies, he must take up his blade to tear the sky apart and protect his world.
