There were many countries on the Magic Continent, and most of them cultivated magical power. There were also countries that comprised purely ordinary people. They were basically in places where magical energy was scarce.
In the magical world, the people in power were basically the most powerful magical family clans in the countries, which were the royal families. Then, there were the various senate members. Most of them had cultivated magical power, especially the generals who needed to go to the battlefield. There were very few ordinary people among them.
There were also many Magi in the army of a country. As the huge army could not be completely made up of Magi, many of the soldiers inside were actually ordinary people.
A single ordinary person was indeed unable to deal with a Mage, but when the number of people amassed to a certain extent, the power was also extremely powerful!
