It was a brisk morning and I was taking a walk along the pavement to the park. I had packed some stuff in a bag to take. On the way, I stepped on a red stone and the ground around me started sinking. I ended up in an underground tunnel. I followed the tunnel until I reached a ladder that continued downwards. The further I went the more it got darker. I found a torch in my bag then kept going. at the end of the corridor, I found a chest. It was filled with lots and lots of gold coins.
