Ayo, time for PHASE XII. The date is 21/9 and for some comparison and perhaps a bit more PHASE VII was back three months ago on 21/5. But apart from the usual hints I bring one concerning the solution, which is something we are all very familiar with in some way or another, but also many of us desire it very much, including me, and lastly it can also be found on this site in other forms.

Goodbye, and rest in peace longcat.
