Magicians who had experienced wars against the demon beasts would knew one thing; the humans were usually the ones being invaded by the demon beasts, who outnumbered them by hundreds, or even thousands of times.
The ratio of talented Magicians among humans was not extremely high to begin with, and the strength of a Magician usually could not match the strength of a demon beast.
The reason why humans were able to fight against the demon beasts for many years was not only because of their intelligence when fighting against wild creatures, but most importantly because humans knew how to utilize natural resources to construct various formations that were a lot stronger than themselves!
