It seems to me that the reason ‘Bai Zemin’ went crazy was because the real Bai Zemin’s existence was found out on this parallel Earth. So if Lilith is truly Bing Xue but from a parallel universe, then the reason she’s hiding her true name is because she doesn’t want Bing Xue to go crazy. So, maybe these parallel universes are like holograms, or something like fake universes because when the Bai Zemin from the main universe interferes with these “holograms” he messes with the original data the Soul Record set for that specific universe. It’s like the Soul Record is a programmer. I don’t know tho, this is just my theory
