"When the Celestial Court was first established, there was an Ancient Celestial Court. However, the Ancient Celestial Court was very cruel and only respected the strong. The weak only deserved to be exploited. Moreover, the Ancient Celestial Court had other secrets that caused public grievances to boil. Countless experts united and various major powers joined forces. The Monster Clan, Demonic sects, Hell, Buddhist sects, and so on. Under the leadership of a few young Emperors, they overthrew the Ancient Celestial Court."
"After that, on the ruins of the Ancient Celestial Court, a few Emperors declared the establishment of a new Celestial Court and built countless huge cities. In these cities, no one was allowed to attack or fly. Everyone in the city had to be treated equally. They also signed a peace treaty with the major powers to allow everyone to develop peacefully. That period of time was known as the Peaceful Era."
