Answer:
If I found a buried treasure chest, I would probably discover pictures from the past and childhood videos. Everyone always like collecting things when they are little! I would also most likely find a key to Middle Earth. (I just love LOTR) Another thing I would find is something that can make you travel very fast.(like apparition in Harry Potter) So I do not have to buy air plane tickets and ride on cars for 4 hours. The last thing I would find would be to reverse, stop and speed up time. Everyone would be thrilled to to go back to the past and pause time, then see what is going to happen in the future.
I'm sorry, cause I don't really understand the topic and I hoped this helped!
