Duan Gujin found it peculiar because he had never heard Qing Lian mention her ability to perform Divination Skills.
After listening to Qing Lian's explanation, he thought perhaps she never told him before, and he remembered Miao Yu saying that for any Divination Skill to be successfully performed, many conditions had to be met.
But the two most important points were: first, the object being divined should not surpass the diviner in strength; otherwise, the diviner cannot divine something far stronger than themselves.
Second, the object being divined should not be too far in the future in terms of time; generally, divination aims to foresee future events.
The closer this future is to the present, the more likely it is to succeed.
Divination seeks the destined plan of the universe, and the closer to the present, the easier it is to approach the truth.
The more complex the divination, the more Spiritual Power and Primordial Power it consumes.
