The wall opened. Cyrus and T.E.D. got out of the room. Suddenly, the passageway started collapsing! Cyrus was terrified. T.E.D. grabbed Cyrus and quickly rolled out of the passageway. They got into another small room. Cyrus was relieved, as he thought he was going to die. "Thank you," he said as he hugged the robot. However, the robot seemed to be a bit confused.

They walked out of the room, and went into a long, hollow tunnel. It was very dark, so the robot turned on its lighting device. Surprisingly, the tunnel wasn't that long as they expected. They walked out of the tunnel and walked into a damp passageway. There were three little lines of words on the wall:

The first one:

TAP ME!

The second one:

TAP ME!

The third one:

TAP ME!

Cyrus was confused. He asked T.E.D. which one he should press. T.E.D. answered:

Thcoaeonp·ne·sd·te··5

What should Cyrus do?

Hint:

• It is actually a scytale cipher. 5 indicates that you should turn 5 times of the band. Commented Apr 11, 2019 at 23:56

• Sorry for late answering. Scytale is used by ancient roman generals to convey messages, especially Spartan people. Commented Apr 29, 2019 at 15:33

Cyrus should:

Tap·the·second·one··

Method:

Skip 4... not sure what the hint implies, or what the 5 was for.

• Sorry I don't understand your method. Could you expand on it please? Commented Apr 11, 2019 at 15:54
• Since both of you are correct, I'll give it to LeppyR64, who answered first. Commented Apr 11, 2019 at 23:55

I guessed the "5" is the clue to tell us that we have to put the letters in the right order.
So if we take each 5 letters Thcoaeonp·ne·sd·te·· become Tap·the·second·one··
So Cyrus have to tap the second line.
I don't get the hint.
