As a mountain god so poor she can hear the coins rattle, Shen Qing firmly believes that knowledge changes your fate.
Later, she called in favors, spent all her savings, and finally got into Nancheng No. 2 High School.
After that
She became an obstacle in the teaching careers of all her subject teachers.
To make a living, she carried her homework to the footbridge on weekends and set up a fortune-telling stall. She told fortunes so well that all her fellow fortune-tellers became her customers.
Everyone urged her to find another way to get rich. Telling more people's fortunes could change her own fate, too.
Short skits:
After the first quiz, the Chinese teacher called Shen Qing in for a talk and she made him say something that came straight from the soul: “Your brain must be worth a lot, because new things are expensive.”
After the second quiz, the math teacher asked her, “Did you give all the knowledge you learned back to your teachers? Then why haven't I received it?”
After the third quiz, the biology teacher asked in confusion, “Are you a cross-species relative of the paramecium?”
Through mutual torment between student and teachers, Shen Qing eventually becomes the top scorer in the college entrance exams and graduates without a hitch.
The setting is entirely fictional.
All supernatural lore in this story comes from the internet and things I made up.
