And also...
In their hearts, there was still a sliver of hope.
Their dragon tribe, that Dragon Ancestor, was also a Supreme Divine Monarch of the Nine Layer Heavens Perfection. Perhaps in the ultimate calamity, there might be a slim chance for him to stand out and achieve the sovereign status.
If that Dragon Ancestor were to achieve the status of sovereign, then a sovereign's existence transcends reincarnation, their body unites with the Great Dao. Perhaps he would have the means to pull them out of the River of Time, allowing them to be reborn. At this moment, by sacrificing themselves to prevent Chen Mu from angering the dragon tribe and interfering with the Dragon Ancestor's final struggle, this was the only thing they could do.
"Causality, causality."
