"Getting infected by bacteria is to fall sick, that's correct, that means developing a fever!" Liuliu suddenly had a burst of insight, thinking of the old doctor's comments about Xiaotian not being able to develop a fever, she decided to use it.
"Oh! So that's what happened! What did you do next?" The old doctor asked again.
"After that, I also first washed the dog using clean water, then I used strong liquor to clean the dog's wound."
"Wait, why would you use strong liquor to clean a wound?" The old doctor probed deeper.
Liuliu felt an extreme exertion. Damn! Earning 200 silver units wasn't so easy! How was she supposed to explain this? Should she say that alcohol can kill bacteria? And then he would ask about what exactly bacteria is? Should she explain again that bacteria are tiny specks invisible to the naked eye? Would anybody believe that? Especially since there's no microscope. Who would know that such tiny invisible specks even exist?
