A Ruin Master's Matrix had to be calibrated to the world they were in. Unless it was created in the True Martial World, even if it somehow held the same calculation prowess, it would still be useless.
When you faced hundreds to even thousands of Ruins in a short span like a Ruin Master, you couldn't possibly be expected to have an expertise on every Dao you came across. This was where a Matrix came in.
Using your own comprehension or computational prowess, you would fuel the Matrix with your own understanding to output the comprehension of a path you didn't comprehend. The Matrix would then output a likely outcome or a list of them, and it was a Ruin Master's job to interpret and act on these results.
A true Ruin Master would be able to clear a Ruin no matter how obscure the path the Sky God that formed it followed. This was the true might of a Ruin Master.
