Review Detail of Eramel_ in Doomsday: I Obtained A Fallen Angel Pet At The Start Of The Game

There are many loopholes in the novel or the MC is just an idiot. The MC do not use his pet efficiently. He should just order his pet to kill zombie to earn crystals. He also said the problem in food or water but the apocalypse had not been a month so there should be many of those in every household or malls. He can just put the foid in his space bracelet so that he don't need to guard the mall. There is also a problem in the grammar probably because it was translated. It is confusing because some numbers are being mixed up.
