Quick Transmigration: The White Moonlight Is a Delicate Beauty

[Peerless heartthrob + love polygon + Mary Sue + love at first sight]

No language, painting, or memory in this world can capture her beauty. She is beauty itself, the tribulation of all living beings. (So beautiful she outshines heaven and earth, so beautiful everyone falls in love with her.)

[World One] A transmigrated-into-a-book supporting character in A Beloved Beauty

[World Two] A universally despised supporting character in a cultivation novel

It's recommended to start with the second world. The first one may not be as well written.
