The reasoning for this is actually that Chi Ying (This novel’s Main Character), has been secretly spreading supplies aka. Food to all the other camps which have her name printed on the inside of each food wrapper making all the receivers ever so grateful for her help.

It’s fine, but this is the main act she does to earn all of the points that she uses throughout the novel (seriously she goes from earning 1 point per act per person who sees her acting to receiving several 100.000 points in just a few days, from an act that took at most 1 chapter to do the first time she does it and is only mentioned in passing for the rest of the 30+ chapters of the book it’s mentioned 2 times in total, at most 3-5 sentences.

And that how she earns all her points that she uses to buy the Anti-Zombie Virus...

In the extra’s the ML gives her a cross as an anniversary present.

Why?

Because back in the first 10 or so chapters her way of acting as a ‘virg*n marry’ was by carving crosses out of wood and placing them on top of the dead zombies.

While not a bad idea it’s was such a small part of the novel that it felt very underwhelming.

The group finds her in the first chapter, ‘rescuing her’ from a few zombies. She hides her powers from them and then follows them for tens of chapters as baggage, basically.

She does help them find out that a later addition to their group is secretly a higher than average zombie with intelligence barely managing to pass for a human by claiming he’s caught a bad cold.

Both her and the ML then follows the zombie to a dark corner where he attempts to kill ML (ML knows but pretends he doesn’t ready to kill him at the first sign of him attacking, because... plot reasons. Chi Ying seeing this attempt to protect him and gets scratched but she’s immune so never mind that. ML thinking she’s going to turn feels bad and spends a few days with her seemingly wanting to accompany her ‘till the end’, but she doesn’t die, and instead claims that the scratch manifested a power instead of turning her into a zombie.

(Something initially presented as a 1 in a 1000 chance and later in the story as a one in a million chance.)

Then she asks to join the team but ML refuse saying she’s got to many secrets, so she spills about all of her powers (while not explaining the how she got them part, or about the system), so she’s accepted into the group but the others can’t know about her powers. Except for the one support power she’s already shared they spent a good 10-15 chapters hiding all her offensive powers until they don’t, and for no reason they just tell the others.

then they plow through zombie hordes until the end of the novel. She’s actually so powerful that the rest of the group become obsolete and are reduced to pick up zombie cores.

At the ending she no longer in the group but has been transferred into a solo team and becomes the government’s extermination tool.

The End.

Early chapters already showed hints of the true color of that Shi team member of theirs, an obvious example was of her getting held hostage my a Zombie Leader after secretly breaking away from the group. And yet in a blatantly dangerous and important mission where they already lost a lot of their Alliance's forces, with little to no information and unclear grasps of the area, they let said problematic healer wander around by herself still. On top of that, after she went missing, they split up individually, and of course the other female member gets caught by the enemy. Absolutely brain dead. The ML, supposed to be smart, careful, and caring totally Just didn't really think much if at all and risked everyone. Even with the of MLs betrayal and zombies rapid evolution, it suddenly was like the new MLs team's brain got stolen, they become worse than brain dead zombies, at least those have more survival instincts it seems.

A few chapters in, of It's revealed that Song Hi was let loose by her team mate cause though not pure they considered her as a friend still. Right, a friend that had recently almost screwed up a mission then screwed up the next big one. Such a good friend. Honestly made me wish for them to become zombies too since they are brain dead already pretty much.

Same with the new ML, saying most reliable and such, when he totally failed in properly disciplining his troublesome team members and pretty much just ran around blindly into danger in the big mission. Don't feel sorry for them anymore, they deserve more punishment even since it seems they haven't learned nor even realized their mistakes.
