The Four Great Ancient Clans of Xuanyuan Nation are existences beyond the mundane, and even the Nine Great Sects of Ancient Martial Arts dare not provoke them. On ordinary days, the Ancient Martial Sects might dare to slightly provoke that small village in the northwest, but when it comes to the Four Great Ancient Clans, they don't even dare to cause trouble, or even know where the clan's young members are.
Fortunately, for over two thousand years, the Four Great Ancient Clans have rarely shown themselves, mostly remaining hidden from the world. Had it not been for the last century when Xuanyuan Nation almost faced the crisis of extinction, the Four Great Ancient Clans would never have made an appearance, let alone meddle in the nation's affairs.
