Obviously the leaders of these powerful races would never allow such a tragedy to happen, so despite their peaceful nature, they decided to annihilate the human races and prevent their rise.
Now, given that the human races survived and the Primordial Gods and Innate Demons are nowhere to be found in the Myriad Emperor World except for a few remains or the Blood Earth Forbidden Land, obviously they did not succeed in their endeavor.
As for what truly occurred, that is something that Wang Wei will discover for himself one day in the distant future.
Back to the present:
The reason that Innate Treasures were mentioned was because they are treasures born from Heaven and Earth back in the Primordial Era through the baptisement of Chaos Qi and Innate Qi. Only a few of them remained in the world, and only a few of the very ancient sects that existed back in the Ancient Emperor Era still have some of them available in their reserves.
