After I Transmigrated into a Book, the System Told Me I Could Change the Original Plot However I Wanted

After I died, I learned that I had been the cannon-fodder villainess in a campus novel.

The heroine deliberately targeted me until everyone around me despised me. In the end, one of her followers shoved me under a car, killing me on the spot.

When I opened my eyes again, it was the day before the heroine first targeted me.

Ding! The Positive Energy System has been bound! Host, you can change plot points through good deeds.

Do one good deed, and you can change one character in the original text!

Do a good deed that twenty people notice, and you can change one sentence in the original text!

Do good deeds that make you famous across the land, and the heroine's halo will be stripped away!

That very night, I helped an old woman cross the road twice and earned the right to change a character.

Original: Bai Lian suddenly fell to the ground.

The next day: Bai Lian suddenly fell to the ground and took flight.

My classmates were all stunned.
