This puzzle is based on a planar linkage that draws perfectly straight lines.
You can see a demonstration here.
Rules
Place the digits 1-9 in every row, column and box.
Digits in cells directly connected by a green line must differ by at least 5.
Digits along purple lines must form a non-repeating consecutive set, in any order. (for example 3-6-5-4)
The line in box 5 is one 9-cell line.

Interesting concept. After clarification of the rules the beginning was elegant and surprising. The rest was a brainteaser. Thanks!

Added Renban clarification and added link to the animation of the linkage.

Nur zum Verständnis: r5c7 r6c7 und r7c7 sind nur auf einer Renbanlinie, oder? r5c7 mit r4c7 sowie r7c6 mit r7c7 dagegen auch auf einer German Whisper Line? Danke

Nein, es ist eine 9-zellige linie. Werde es in die Regeln geben.

The process was very difficult, sorting out their relationships bit by bit, and finally I got the answer. That's a good puzzle. Thank you for setting it up
