Yan Lai transmigrated into a book.
It's a space opera with a spiritual qi revival, where everyone worships magic. The male and female leads have extraordinary magical talent and are beloved by the gods of magic. They're basically overpowered protagonists in a magic fantasy.
Yan Lai, on the other hand, is just a cannon-fodder supporting female character in the novel, born a "useless waste" with no talent for magic.
She transmigrated right at the end of the story, after framing the female lead. As punishment, she's sent to the most desolate garbage planet, where she's about to meet a bad ending: being humiliated to death.
Yan Lai: ...
She gazes at this unfamiliar world, with no nations and no old homeland. Step one after transmigrating: stay alive at all costs.
Then one day, while living on the garbage planet, Yan Lai finds a strange treasure:
Vermilion Bird before her, Black Tortoise behind; Azure Dragon to her left, White Tiger to her right.
Yan Lai recognizes it: the Four Symbols, the totems of Huaxia.
At the same time, an unfamiliar electronic voice sounds in her mind:
[System bound.
Quest One: Build a cultivation academy.
Quest reward: One specially invited professor, Great Sage Equal to Heaven.
Host, please complete the quest as soon as possible.]
Later...
In this age of magic, no one expects a group of people to burst onto the scene.
They have a cultivation system unlike anything seen before, one that requires neither complicated incantations nor the favor of the gods of magic.
They ride the clouds and mists, bathing in heavenly lightning.
With a single sword strike, they cleave mountains and rivers.
