Li Fan had no intention of deriding.
The original "Mountain-Seating Secret", indeed, was not created by a cultivator.
Where it came from specifically can no longer be known.
But according to the records in the technique, if the initial version of the "Mountain-Seating Secret" wanted to elevate cultivation level, one could only rely on "seating mountain".
Depending on the chosen mountain peak to continuously elevate its height to obtain corresponding cultivation feedback.
This process was overly long.
During ancient times, the mountains and rivers didn't change as easily as they do today.
A mountain peak often took thousands of years just to increase a little in height.
If the "Mountain-Seating Secret" wasn't a joke, it might have been meant for trees and rocks on the mountain, rather than human cultivators.
