Bro is hunger of validity
First of buddy, Laws can be concepts, Concepts was established to structured said reality, so does the laws of Teyvat. There is no contradiction whatsoever between "laws" and "concept."
The Four Shades are described as:
That means they are not random rules, but foundational governing principles of reality in Teyvat. If they "anchor the world" so they must be ontologically prior to it, thats why Dottore said they have transcend its boundaries.
After all, the laws are literally four metaphysical aspects, which is Life, Death, Time and Space, those are literally Concepts.
