Do you guys know any stories where a modern MC is summoned all around a fantasy world(s).

I remember a webnovel I once read where the main character, a teenage girl, started to get summoned to fantasy worlds to help her summoner or summoners with various things. It ranged from asking her about arcane knowledge (knowledge of physics and chemistry helped with those), to something as simple as cleaning a room.

I'm sure that she was summoned once by an elven king who asked her how to make their forest healthier, and she told him to cut down and burn parts of it because the trees were too close together and didn't allow sunlight to reach the forest floor where the samplings were.

So, yeah. If anyone knows how it was called I'd be grateful if you could share the name, or another story with a similar plot.

I couldn't care less if it's a book, light novel, or webnovel. If I can read it, then it's perfect.
