Hey

I think so... I still remember the explanation a certain fallen angel gave to Jihu about the reason why the angels are there in Lost Paradise.

While NU mentioned that both works happened in the same universe, it didn't really mention that both story happened in the exact same world-plane, because the unclear hierarchical structure of the worlds...
well, you know what I mean... in those CN martial arts works where many worlds are connected, there's a clear stratagem of world (lower, middle, high, or something like that)

Yes it is, as the Parasite Queen fled when the mc from MEMORIZE established his reign. You can say the very reason all the shit happening in SCoG due to PQ fleeing to Paradise is due to that.
