Since several tens of thousands of years ago, after the Berserk Mongrel Rodent Clan had perished together with the Golden Hellhound Clan, all that remained was just a branch in each clan.
The branch managed to survive until today.
However, in order to recuperate from the battle, they had learned to conceal themselves in front of others.
At that time, they had too many enemies. If it was made known that a branch had survived, many people would come and attack them in a flurry.
The Berserk Mongrel Rodent Clan managed to conceal their existence during their recuperation period.
Perhaps, the Golden Hellhound Clan was truly the mortal enemy of the Berserk Mongrel Rodent Clan. One branch survived in the latter, and the former was also left with one branch.
Ever since then, the two branches from both clans had always fought with each other.
They were well-matched in strength and fought for another 20,000 years.
