Of course, Shuangshuang didn't tell the other party about overly complex ways to eat it. It's not that Shuangshuang is keeping secrets; even if she told them, they might not learn it. So, Shuangshuang only shared two ways to eat it: one is to spread it on meat as a barbecue seasoning, and the other is to soak it in water to drink, which can prevent dryness and aid bowel movement.
Shuangshuang's straightforwardness instantly moved the other party. The ability to relieve dryness is truly great. Their tribe knows little about vegetarian foods; their main food every day is meat, and they often experience dryness and heat issues. If honey water can really help with this, it's a huge benefit.
The man was overly moved by Shuangshuang's sincerity at this moment, thinking this girl is too honest to tell him such things, without fearing they might never sell her this good stuff of honey again.
