If forced to produce an answer, I’d say:
Actually, ROT15 forward: t(20)+15=35 mod26=9→i, h(8)+15=23→w, m(13)+15=28 mod26=2→b, y(25)+15=40 mod26=14→n, l(12)+15=27 mod26=1→a → “iwbna” no. thmyl — they? t→t shift 0, h→h 0, m→e? m(13) to e(5) is -8, inconsistent. aflam — have? a→h +7, f→a -5, no. 15. Perhaps it’s a cipher like “every letter shifted by +1, but word boundaries scrambled”? Doesn’t fit. Given the short time, one possibility is that it’s ROT13 on each letter, but you made a typo in the example. Let’s test the last word “mtrjmt” — if ROT13 → “zgewzg” no. If ROT5 → “rywory” no. But if ROT13 on “bwd” → “ojq” no. However, I notice “hyl” ROT13 → “uly” — “uly” isn’t English, but maybe “you”? y→l shift +? y=25, l=12, diff -13, yes ROT13. h→u is +13. So “hyl” ROT13 = “uly” not “you” though (you would be “lbh” in ROT13). So not. Given the pattern, I suspect this is ROT13 but the text is not English — maybe it’s another language? Or a simple substitution. thmyl aflam bwd sbnsr wtrans hyl mtrjmt
But the problem says “solid piece” meaning one consistent transformation. Commonly, such puzzles use . Let me apply ROT13 to the whole: If forced to produce an answer, I’d say:
guzly nsynz ojq foafe jgenaf uly zgewzg
No meaningful English. Given the constraint, I’ll guess the solution intended is , and the decoded phrase is nonsense because the original might be a name or code, not English words. m(13) to e(5) is -8, inconsistent
thmyl → guzly aflam → nsynz bwd → ojq sbnsr → foaf e? s(19)→f(6), b(2)→o(15), n(14)→a(1), s(19)→f(6), r(18)→e(5) → “foafe” wtrans → jgenaf hyl → uly mtrjmt → zgewzg
