Sorrest
You know, she could buy a poison resistance skill, and she would evolve this skill so much, that in the future she would be immune to the zombie virus, that is, even if she is bitten, she will not be turned into a zombie, and then leak the information about her being immune to the zombie virus, and then the military, scientists, clans/gangs and the old government will go after her to study her and find a cure, but consequently she needs to die, and she doesn't want to die, and so a hunt begins to capture her.
