Chapter 4270 - Xue Ying

There were 18 Realms of Gods, and there were nine Realm Battlefields, which were created from the intersection of two Realms of Gods. However, every 100 years, the nine Realm Battlefields would intersect in three groups of threes, creating three chaotic regions respectively that would stay open for a decade. This meant that the intersection of six Realms of Gods would create a chaotic region.
