Review Detail of HeartRend in The Zombie System

Story is interesting and i will definitly continue to read it. However i have a few issues with the author. 1. He/she/it promised us 13/ch per week, now I'm not so stringent on that number, I know how hard it can be to right and how one can burn out by going too fast, but I was hoping for at least ONE chapter every day or every other day with the way they promised us. However, for the past few day's, no new chapter has been put up. 2. The MC and the "First Wife" fall in love/move waaaaayyyyyyyyy too fast. I understand the MC has feelings for the girl from the past life, but even then they were only friends and had close relations then, him caring about her is fine, but proposing to her on the first day? Kinda far fetched. 3. The "First wife" actually accepts a "marriage" proposal by the MC even though they have only interacted once in her life (i.e. that too only when he "saved" her or something). The MC never talked to her again, yet this girl not only falls in love with him (kinda understand the hero-worship she feels, but a little extreme), but she actually agree's to marry the guy. Like wtf, she knows very little about him, only that he "saved" her once, and is a super rich billionaire. Like wtf, talk about shallow. 4. MC just happens to be a multi-billion dollar company heir that throws around money like dirt. People should understand that those who get to those levels have more value for money than that. I understand the idea that since the apocolypse starts in 5 years, money is worthless after that, but that is still 5 years away. With the way he spends money, i won't be surprised if he goes bankrupt the next day (but since the author does not say how much money he has, they can keep the money flowing endlessly lol). For a take on it, he already spent nearly a billion dollars in a few days, with plans to spend nearly a billion more after his "projects" are done. 4. Unrealistic pricing. He spent $5-$10 million per "combat maid". Maids who can fight and have "undropping loyalty". Like wtf? And he buys a hundred of them too (nearly a $1 billion). I understand that these maids are probably trained excessively, but human life is cheap af, especially on the black market, and how much can training cost be for their prices to be soooooo high. Also, his building project around his mansion cost over $1billion as well. Like WTF? Take into perspective that the Burj Khalifa itself (the worlds tallest building and a luxury hotel) only cost $1.5 billion to build, and this guy is spending that much on merely his mansion. Like wtf? Anyways, I will still continue to follow and read this cuz I like the story, even with how unrealistic and crazy it is. Only wish author actually UPDATED.
