Synopsis：Hidden as a humble servant, he turned out to be the supreme Beast Lord who could command all the beasts! In a world dominated by humans, where nobles reign supreme and filled with the dangers of monsters, the protagonist Eric (Eric) initially appeared as a lowly servant with no background, suffering bullying and contempt in the nobleman's mansion. In a society that reveres power, he was often ruthlessly trampled and ridiculed by arrogant nobles and knights. However, no one knew his true hidden identity - he was the "Beast Lord" with the supreme bloodline, capable of forging a pact with ancient beasts and commanding all the beasts in the world. He chose to hide his sharpness and was willing to be a servant in order to secretly investigate certain unknown secrets (such as the cause of his parents' death or the revival of ancient powers). The turning point occurred during a sudden catastrophic event or a life-or-death duel among the nobles (such as the Blood Moon's arrival, the siege by the beasts, or the relentless pressure from arrogant nobles on his life and death). When the villains thought they could eliminate Eric as easily as crushing ants, he finally stopped hiding! With his call, divine retribution descended from the sky, and the originally fierce and violent ancient beasts and the army of monsters, who could not even be tamed by high-ranking knights, all knelt obediently before Eric, respecting him as their lord. Those who had once laughed at him and bullied him, the nobles and hypocrites, were terrified out of their wits and knelt down begging in the face of the terrifying roar of the beasts. Eric, in his absolute strength, overthrew the arrogant noble alliance and wrote his own myth of commanding beasts.
