Was thinking about this show and realized that the Time Goddess has to be the Primordial God that created HRY and BJS. Because she's the one watching over their love trial and at the end, she used HRY's power to create BJS again.
Based on the discussions I have read from cfans, the reason why Xi E is not included in the list of the most important…
She destroyed his lol. Then at the end she tried to give hers to him to save him, but he chose to give it back to her to fight the villain. So he died and she went on to beat the villain. Then, after maybe hundreds or thousands of years the Time Goddess somehow used her pearl to make his because they're born from the same place, so he was resurrected by that.

She destroyed his pearl when she was trying to kill him. He also took out her pearl that she gave him and then died. The time concept is hinted that she's been task with overseeing their tribulation.
Time Goddess = Primordial God I'm guessing? Or is she just the only one tasked with supervising Hua Ru Yue and Bai Jiusi's love tribulation. Because I remember Bai Jiusi asked the Time Goddess why she's not on the list of the most important Gods. She said it's because of something but never told him/us why.
It's not easy for her to open to him after what he said, while sealing her powers. He made he think that he only…
She thinks BJS is only using her to get past his love trial. Because that's what he asked her to help him with the first time they went to the mortal realm. She's not too sure that he's truly in love with her and cares for her. She also thinks he doesn't care about humans at all because he truly does not believe in meddling in the affairs of mortals.
so he was resurrected by that.
