You go through into room five. There is a standard keyboard, and, of course, the paper:
Pidi ou nto seeob r thf ruusnei yeivboae f t .eoqo vrs rwlmdthuih rrlweyoei
You can just make out the carving into the wall.
Kwei sdoa c etfcbeqs zvcd, ukl ghcds'u lwkweivkxu hd. E uvhdcdf hkoza-kqwi ifsdt!
There are eight-million, four-hundred and ninety-six thousand, three-hundred and twenty-one pies.
What is the word that you should enter?
The wall carving is actually a hint to the paper. You don't necessarily need to solve the wall carving in order to know the puzzle. If you do want to, however, know that the bit about a large number of pies is only important to decrypting that unimportant cipher. So, spend most of your time on the paper, for decrypting that will give you a word.
HINT 2: This is what is written on the wall carving, don't read if you want to work it out yourself.
Much like a skipping rope, the paper's cipher be. I skipped fifty-four times!
The next door will be added when this door is solved!
