as long as you've found the map chips you should be able to know which areas you need to look into. You could also use an external tool like the nine sols interactive map[ninesolsmap.com] to find them. If it's your first time collecting them all you'll know when it's done when the achievement pops. Chiyou also sells a good amount of poison you need to buy, but I've made the assumption you bought all those.
