Quick Transmigration: Life Is a Breeze, So I Travel Everywhere

Yu Yuan, the heroine, can travel through time and space with the help of a System. She journeys between different eras and parallel worlds,

helping people fulfill their wishes (just because she feels like it; she doesn't have to help), and changing their lives (though she doesn't have to change anything). She might even take over the original person's identity. (Not sure if there'll be a male lead.) She eats, drinks, and enjoys herself, while sightseeing and learning. She's lazy, lives the good life, and takes a laid-back approach, occasionally doing a good deed. She's no self-sacrificing saint, and she doesn't necessarily assume the original person's identity. At first, she's a soul; later, she has a physical body.

The worlds might be from books (though they won't necessarily be exactly the same), movies, TV shows, or games, or they might be fictional primitive, prehistoric, cultivation, interstellar, modern, or ancient settings. Who knows what else? I'll think of it as I write.

Worlds I've thought of so far:

1. Saving the Jia family as Yuanchun from Dream of the Red Chamber.

2. Mary's a teacher in Pride and Prejudice.

3. Steve's underground entertainment city in Minecraft.

4. A lucky star descends in the 1960s.

5. Poppy, the great demon king of Bandle City.

6. A super-lucky, all-around lifestyle player in a full-dive game.

7. Love in the Courtyard.

8. A parent-child variety show.

9. A cultivation world.
