"This world has five Major Continents, and we are currently in the Eastern Continent."
"I am aware of that, but how could there be five continents when I've been told that there are only four— one in each direction?"
"The fifth continent is the Holy Central Continent, and it is located in the middle of the other four Major Continents. Each continent is separated by a vast sea called the Jade Sea, and it is not something easily traversable by the people of this world, as only those at the Heavenly Spirit Realm can fly without the assistance of flying swords, so I wouldn't be surprised if not many knew of its existence."
