first the MC sometimes adapt an ugly murderer mentality, like when he faced a difficult opponent, what's the words that he left for his closer women, "if I didn't return kill all the other companions, and keep the provisions for yourself", the women on the other hand didn't get surprised. Again the author make a bold ugly claim as universal truth he says "No man would not want to eliminate their competition in the name of love" as he and his current girlfriend killed the boyfriend of another girl that he has a one night stand at the beginning of the apocalypse, and then abducted her, well the author could easily make this event logical but he choose to make it crap.
As for the event I feel that author lost the compass, just as the MC and co took the highway exiting the city, a volcano erupt along with earthquake, fearing it, waves of monsters started dispersing, so the MC started killing those that runs their way, tons of them witch just a few day before he has serious problems facing just one, and those monsters have the intellect to run from volcano not to avoid a path full of death, so they keep pouring in the MC way, just to make a ridiculous scene of shonen level. Then just as they survived a volcano, a flood occurred, is this a contest of natural disaster!!! Not long after they found themselves inside a nuclear radiation zone?? And they immediately found a plant that heal the radiation problem.
And there is that thing that I overlooked before, the MC power came out of his willpower so as he continue training his willpower he came to realize that he can do anything at will, he wanted light, so light manifested itself, but it seems that the author understand how ridiculous this idea is, and never mention it again. Edit: coincidentally I read yet another chapter and he used his will to heal a women, he make up for it saying that it consume quickly his willpower, this unstable power make for bullsh*t story when the author make thing easier for himself, using it when he shouldn't and vise versa making bullsh*t excuse, yet this is my own forsee.
So the future looks dark for me, I lost hope that I found in this novel, I'm out. It's really better make a quality story of 100 chapters than to go for 1000 or more crap, the fandom culture isn't healthy I think. It encourage author hooking people with quality at first then feeding them anything next.
There is this one stupid thing that keeps annoying me throughout the story, the MC got a elf ears thing that bothered him to death, and may cause him serious problems, but the MC never asked the people who may has the ability to help him, actually his secret friend promised him to help him if he do him a favor, but the MC never asked him later, and the whole story he was hidden them with some stupid ear muffs, that no one pinpointed how strange is that. What's more annoying is that the problem is gonna be solved randomly later.
even now for example in the chapter 3 the MC started learning smiting but he spent 5 years just so that he could make sword that could be considered having an edge, even a caveman or a monkey would be able to do better with only a rock and a peace of metal, while the MC has the all the knowledge of modern humanity and all of it's resources, this is ridiculous, even if the MC does no matter what, say he split the moon, I can't perceive him op considering the amount of time he spent on learning things, the only commendable part about him is his persistence.
even making the gods witch could control time and space unable to trap a bunch of monsters in a dungeon, asking for the MC to help them do that instead. And while the MC keep whimpering over being alone, but the truth is he is the one that choose that, even set his goal on becoming a god (i don't know who told him that he could be one) so he could be in the same level of a woman angel that he like. Then find her
for the sake of a loner plot at the start the author didn't make any survivor out of the 8 floor building that MC lives in nor even the surrounding, he is the only survivor of the area. The only few that he saw, were ate by the zombies right away, well it's possible but find it boring and lame, 20 chapter about a negative MC alone is so monotonous, and suffocating for me
even when he goes to USA, after a year he decide to go back to Japan without saying goodbye to his supposed closest friends, his secretary and a shop owner, and when his secretary followed him to the airport crying that she loves him, what did he do!!! He kissed her and said goodbye without accepting her feeling and thought to himself "Its great to have a passionate kiss with a blonde beauty~! It was worth it to come to America" yeah it's greet but she's supposed to be a trustworthy friend of yours bastard
the MC starts to overly relay on the help of summons (he spent 100 years grinding only trying to gather orbs needed for summoning, he didn't try to improve himself during this time at all), and he start to be overpowered by enemies his level or lower considering that the MC is higher than his numerical level and with his top notch equipment. The MC personality also started to feel unstable, he started as a calculating man only to discover that his true personality is the inverse hotblooded, then now he is neither, he start to seems a like a stupid coward, though all of that is not extreme, and justifiable so the story is still good, but it started to get annoying.
The author is persistent on making harem for the MC by the same way, help a damsel in distress, then fell in love with her afterword just to find a reason to separate without starting a relationship so that he can keep his harem collecting.
again the MC for some reason keep collecting an invisible harem of goddess that grant him blessing for no reason witch isn't funny for me at least.
loopholes the MC is supposedly the strongest, the fastest, the most dexterous, but an S class beat him so bad because of skills, I can't understand this. A villain lord was able to send him flying and kidnapped a woman he liked. He helped a princess while she has a butler that seems as powerful as him, this butler was pretending to be captured to spy and said that he heard what he came for, but didn't deliver any information in the end. Anyway the author is a lot loose with the plot.
for example his monthly allowance as a young master is only a few silvers and his hole clan wealth is 1000 gold, yet when he demand a favor from his little sister she asks for a payment of 100 gold, then 200 gold when he accepted and even threaded him if he refuse, witch is supposedly a funny thing, hell no it's an angering ridiculous bullsh*t, I'm not sucking on my thumb
