The living beings on their own territory, if they did not worship them, were naturally going to be eliminated.
They felt that they could completely control the lives of all the beings in their own territory.
Although Suiren was a Supreme Level strong, after all, he was just one person.
Just a Suiren, they were not afraid of him.
If someone truly dared to make a move against them, the Primordial Gods and Demons wouldn't mind joining forces to eliminate a Supreme Level strong first.
Out of disdain for the living beings of later generations, they simply did not believe that Suiren, a mere human of the Supreme Level, posed any threat.
Even though he had reached the Supreme Level, the Primordial Gods and Demons also believed he must be the weakest among the Supreme Level strong.
After all, the Human Race is inherently frail, a fact that cannot be changed by anyone.
Even as a Supreme Level strong, he would definitely be the weakest, without exception.
