OK thank you. Well, first I defeat the boars guarding the entrance bridge. then I enter a store to get the items. then I enter another warehouse (I get more items), I face the wild boars that are there (I get more items), when I leave the warehouse there is no one nearby, I wait if a wild boar approaches but nothing happens. then I move to the right where I find a group of wild boars (there are 2 of them). I defeat them. but I don't get key...
