Comments of chapter undefined of Journey of the Fate Destroying Emperor

I mean how does he even remember it? Didn't the eternal emperor destroy the beginning/origin of Buddhism so that it never existed? So how does this guy still know about it and remain unaffected? If the beginning of it is gone how does he still know about it? Also, he was the one who almost bought an end to the whole world community and he did the same by giving hits to that other girl. Would the heavenly will rly allow this? or at least without side effects? Furthermore, how does he hide in the most dangerous forbidden land easily when he is nowhere near the strength of the eternal emperors? If it was so easy that they just had to hide their presence to enter then surely it would not have all died? Idk but this whole arc to me seems interesting but it is forced af. Does it seem that to make the story more interesting some parts that were mentioned before are ignored? Love this story anyway aha
