Leng Pan didn't want to imagine a world where the zombies evolved too fast for the humans to catch up and fight.
She realized that, probably because of her transmigration, the plot of the book had changed a lot.
Something like this didn't happen in the book. Even though zombies evolved and grew stronger, they were controlled to a certain level and couldn't surpass some humans.
However, now some uncertain factors have been introduced. Some people had changed. Others who died at the beginning were still alive.
It had become some organized chaos. The plot was no longer useful as a reference. Even though some things still matched, many had changed and she would have to play it by ear.
But unlike Leng Pan who was a character created by the author and following a scripted life to become cannon fodder, she was different. She had sentience and could choose her own destiny.
