This is an entry to the Fortnightly Topic Challenge #27: treasure-hunt.
Last weekend was fun. We went on a trek to a nearby place located in the middle of a huge jungle. We decided to set up camp there. Though a couple of my friends argued with the idea, the rest of us were excited.
It was almost midnight when we decided to check out our surroundings. We had walked only a little way when we saw some carvings made on a tree. We were not sure what they were, but they seemed interesting. We lit up our torches and started examining the art more carefully.
We noted it down on a piece of paper and tried to solve it. It took us some time to figure out what was hidden there. But what we found out was - EXCITING!
We moved ahead with that note and came upon a similar tree right nearby, pointing to the tree we had just visited. This time we knew what we needed to do.
It was not exactly the same, but well, upon observing more, we got what we needed and why those trees were right next to each other.
We went ahead. There was a cave nearby. We went in and to our surprise, we found a locked locker with a note. The note had one readable line followed by some nonsense characters; it looked like this -
DO YOU HAVE THE TWELVE? GO AHEAD AND FETCH THE NEXT NINE(4,5)!

Once we had decoded the note, we found a riddle hidden inside it. We were sure the combination for the locker was hiding somewhere in this final riddle.
Can you help us break this final twist to find the treasure?
