I became a zombie and was picked up by the heroine

Gu Yao confusedly transmigrated into a novel she had read, and then became one of the short-lived schoolgirls who was bitten by zombies. The only label on her body was the former Bai Yueguang of the male protagonist.
When Gu Yao passed through, the original body had already been bitten by a zombie, so what she faced was the hell-level difficulty opening where she was about to become a zombie.
Broken, die in peace.
However, she never dreamed that...
The self who turned into a zombie was actually picked up by the heroine.
I didn't expect that the heroine in the novel turned out to be a crazy critic in private.
So the novel is also called——
"Zombie Breeding Manual"
