XIETIAN
So first we were going to Russia to get Evangeline's payback, then we fought the Mana Eater Tree, then we abandon Russia to go to the summit in Rome, then we go to the East Sea for Hero City, then we fight the pope and take his spear, then we almost kill the Demon of Corruption, THEN we get stuck in the center of Hero City with the Throne of Creation, THEN the assassination attempt by the Dragon lady, THEN BZ and Khristina (for some reason) are stranded in space, NOW A PARALLEL EARTH.... This story is going in too many different directions at once imo
Can this be considered the last piece of the puzzle? Anyways parallel Earths exist so Lilith's background is now obvious. The fusion needs to be confirmed though. It also seems that Lilith has the ability to travel through space with her second firmament fragment, so that's probably how she got to Bai Zemin's Earth. To be honest I remember author described that firmament fragment as giving off a blood smell. Then later on he said she has a high talent for space because of it. I still can't guess whether its focused on blood or space
