C237 Posterior mountain soporific sound

Little Boss told me to go to that box to get something, but didn't tell me what it was in secret, and even said that there was only one thing in the box. He also said that if I didn't find anything when I went to the box to get something, then I wouldn't have to come back to see him.

By the time I reached the top of the mountain, I was completely exhausted. It was almost three o'clock
