Beigong Yu left the Pangu Human Clan and headed straight for the territory of the Hongmeng Dragon Clan.
The Hongmeng Dragon Clan had once been the most loyal ally of the Pangu Human Clan. Later, because the Pangu spacetime was shattered, they also suffered heavy losses. Ultimately, they migrated to other spacetimes to eke out an existence, eventually growing into the overlord they were today.
According to Grandpa Huang, the Hongmeng Dragon Clan's achievements today were inseparable from the backing and support of the Pangu Human Clan.
