she's physically weak as a zombie, but she has an ability that could suppress other zombies regardless of how strong they are, though she didn't realise it herself.

how the government worked so hard to protect its people and tried their best to help zombies regain their humanity. While it described how other countries kept trying to dominate the world through the zombies, as if China is the only country that tried to help the world. Obviously that's BS. We've seen how China handled Covid 19, they didn't try to stop the virus from spreading to the rest of the world, and in fact they even used this virus to gain more control over their people's lives.

the reason why the goverment in the novel was so organised was because there was a reborn person, this person was someone in a high position so it was easier for him to do certain things. According to this reborn person, the MC buried herself in summer in the 2nd year of the apocalypse, so yeah... she died quite early, so that reborn person basically changed many things. There were also other people with systems from different worlds but was never explored, maybe because author was too lazy and because they weren't an important part of the story.

MC's way of thinking started to change and became much happier after she met her dog named tyrannosaurus rex, but she still handed over the dog to someone else because she decided to hand herself over to the gorlverment to participate in the experiment. Of course the experimentwere not harsh and they treated her very well because the protagonists were in charge of the goverment.
