There is a continent called Theo. The land here has nearly 5,000 years of history. Since the massacre of gods and demons five thousand years ago, this continent suddenly appeared for 5,000 years. People on this continent live a happy and prosperous life. All peace in the world is actually attributed to the events of the massacre of gods and demons. At that time, people with high magic power in the world signed a treaty with the demon world. The well water does not violate the rivers and waters, each of which has three powerful powers passed down from generation to generation, and each guards its own acre of three parts of land. This has created today's peace.
