Thmyl Wyb - Brw 9

If it's :

Third word brw → yid

Let me know what kind of "feature" you have in mind — encode, decode, validate, generate, or integrate into a specific system (Python, JavaScript, game, etc.) — and I’ll write the exact code or logic for you. thmyl wyb brw 9

So "guzly jlo oej 9" — also not clear.

thmyl → guzly wyb → jlo brw → oej

"thmyl wyb brw 9"

Second word wyb → dby

Could it be (each letter shifted to a neighbor key)?

So Atbash gives: "gsnbo dby yid 9" — not obviously meaningful. If it's : Third word brw → yid

Could you clarify what you mean by this?
