On this planet, the status of beastmen is very low.
It's not just in terms of social status. Even when it comes to combat, a beastman ranks very low. If it were to be compared to an RPG, a beastman would be equivalent to the beginner-level slimes or goblins players encounter at the start of their quest. Even Ratmen pose more of a threat.
Ratmen can manufacture their weapons, enabling them to hold their own against various races. But beastmen are different. They don't fabricate weapons and only rely on their bodies and claws in battle. The most they can do is pick up fallen weapons of their victims in the battlefield. That's their limit.
Of course, one can't be sure of the usefulness of such poorly maintained weapons.
At least for people like Duanmu Huai, even a surprise attack by beastmen presents little threat.
