Fighting Demon Continent: My Wife Is an Angel

This is a world called the Demon Fighting Continent because people in this world can practice two professions, namely knights who practice fighting spirit and magicians who practice magic. Some people say it is because of the battle between humans and monsters. There are tens of thousands of races on this continent. We call those other than humans Warcraft. Warcraft include dragons, unicorns, giant apes, lions... And countless others. The human race is dominated by humans who think they are the leader of all things, followed by the dwarves, giants, elves, and orcs. We classify them as humanoids. Of course, our special way of life is called human race by humanoids and warcraft, and is considered alien by them. Five hundred years ago, human worker Watt (I solemnly declare that this is not the earth, any similarity is purely coincidental.) Invented the steam engine, and mankind entered the industrial revolution. Three hundred years ago, human scientists Edison and Tesla invented electrical appliances, and mankind entered the electrical age.
