Had they ever watched a zombie movie in that world? It is said that when they first appeared, people did not know what kind of monsters they were, only after a long time that they named it based on a reference to an old movie about zombies,

about their weakness in early chapter, are they didn't have observant people? Are they just blindly cut the zombie without observed their state? Why when only MC said their weakness like it never slightly passed their mind before when they named it after old movie?

oh and about Daehan Guild, MC seems not recognize their face even though they were famous guild,

about government, they seem incapable to manage their country, even they lost to Daehan Guild

MC seems s*upid and closed minded, when they form team she ask why she is not in tank or healer position, did she forgot she is just got class switch to tank just recently without experience and about healer didn't her skills only apply to herself

too many ask why each conversation

the red haired guy, MC seems already said she had zombie regeneration skill but he like didn't know it and arguing with MC about being reckless and make unnecessarily move

reading this like reading C-novel

the change scenes, I don't even realize when they suddenly change scenes, example : when they still in meeting room for discussion plans suddenly the next conversation they already in different place and different subject and people. The transition between scenes is confusing

it seems not only MC who didn't know the famous guild members face, even other guild too (how ironic/the plot holes is glaring)
