Well you could go read the WN translation to find out but if you don't feel like it the answer is once she realizes she's probably responsible for the undead she releases a purifying flower that eats rot(both the undead but also just general filth) into the river and around the edges of the forest to contain the spread.

I admit I am not much of a book reader that isn't Warhammer 40k or the Distortion Detective series. 😅
I tend to find the LN or WN of a lot of isekai boring and couldn't retain much attention. And this is also the person who skims two paragraph long Yu-Gi-Oh cards on the daily. 🤣
