What I could understand is that seeing the future is something related to the soul.
1- the only thing different about Shui Meiyin and his Divine Soul Stainless
She could see in the future that the plan to seal the red slit was going wrong, preventing her father and siblings from going.
Xia Qingyue says she saw the future.
The moment he saw the future was when he was receiving the inheritance, and from what is explained in the story every time a cultivator rises, his body and soul also rise. At the time when Xia Qingyue was receiving the inheritance, it was the most sensitive moment of her soul, allowing her to see the future.
So why couldn’t Yun Che see the future?
Yin Che has - several divine souls in his body, he is a person who passed by Samsara (he used Samsara’s mirror), there were times when his cultivation level increased rapidly (when his soul must have been sensitive), he is in direct contact with a heavenly treasure that controls time (mirror of Samsara).
So why couldn’t he see the future once?
See the future?
It is easier for Xia Qingyue to have been deluded into a larger existence.
Xia Qingyue = no content.
