Actually, by now, Duanmu Huai has almost guessed what the cause of the incidents in this place is.
If he is not mistaken, there should be a Blasphemous Artifact here!
The so-called Blasphemous Artifact isn't an artifact corrupted and twisted by the Evil God. Strictly speaking, its origin is more like... a relic.
As mentioned before, in the aftermath of the Black Hole Project, to weaken the potential followers of the Evil Gods, surviving humans carried out the second phase of the God Creation Movement. This led to the emergence of many different deities across the universe. Admittedly, these deities were not as strong as the Four Great Evil Gods, but objectively, as long as they existed, they would compete with the Four Great Evil Gods, who were trying to regain their power, for believers and souls. They were, in effect, obstacles in the way of the Four Great Evil Gods.
