The origin of the goddess of creation was somewhat unexpected to Hao Ren, but it was not too shocking.
After he learned about the incredible existence of the "true God", Hao Ren had ample mental preparedness concerning the background of the goddess of creation. There was already a deep-rooted mindset in him. Regardless of how she was born and what her relationships with the higher-order gods, who were part of the Xi Ling Celestials, or the Galacticus Lords were, they would all be acceptable to him because the true God was unreasonable.
They did not even care about Physics.
Everything that humans understood was a byproduct of these supernatural forces, even the incomprehensible parts of this realm. Hao Ren had long understood that truth, and for the same reason, what Raven 12345 said was not a surprise to him. He only wanted to know what the plan of his boss and the boss of his boss was after he learned of the secret.
