If a great clan couldn't even protect those species that relied on them, then there was only one outcome: all the smaller tribes affiliated with this great clan would lose faith in them and then depart from their alliance.
This was precisely why the Primeval Qilin was so furious.
If this continued and they remained inactive,
The species that depended on them, the Qilin, would become disheartened.
Thus, they would choose to leave and ally themselves with others.
And if the Qilin lost these smaller tribes, they might very well become much weaker than the Dragon Clan and the Phoenix Clan.
Under such a dynamic of loss and gain, this could very well determine the survival or extinction of a great clan.
That's why the Primeval Qilin was so anxious,
Even if it meant starting a war with the Ancestral Dragon, he was determined to kill Sun Wukong.
