Those who cannot handle the mortal tribulation effect, fade away- it was mentioned when that white haired former heavenly sky emperor returned. Su Su was suffering from severe depression and PTSD( she couldn't tolerate Ye Hua's touch and became very afraid of him after he took the eyes). Her memory was also impaired a bit when she jumped through the portal leaving her confused. Only thing she remembered very acutely was very deep sorrow and pain. So Bai Qian might not have made it. If she didn't take the potion, Ye Hua would never have gotten a second chance with her. Frankly Ye Hua was not much better to her than his uncle till he learned she was Su Su. He too neglected her. Bai Qian already had become a joke after his uncle's stunt. She was also disappointed that her father accepted marriage with next heir who was not even born at the time- she immediately understood that it meant she couldn't find any other suitor either. Because technically she would remain engaged for eternity even if no heir showed up. She had stopped attending any event and reclusive and wouldn't go out of her Fox Tribe domain to avoid the drama. ( novel explains) On top of it her mortal tribulation turned out to be abusive in laws and husband and scheming concubine in the same house, she was engaged to as an Immortal. Nope. If she didn't take potion, Ye Hua would never be able to get close to her when she became Bai Qian again.
