You had just made it to a Japanese building called the "pagoda", home of a Japanese goddess named "amaterasu" she was known for giving a choice of either making a offering (Can be anything), or challenging her, both will result in her gifting you something if you do it correctly, you go inside and around the 7th story and see her in the doorway

amaterasu: hello mortal... are you here to make a offering? Or are you here to challenge me...
