To those of you who are scrolling in order to decide to read a story, here is a real review. Most of the bad reviews (especially the spammer of bad reviews "reign333" <-- posted multiple bad reviews on same story so a troll) don't really have any backing to them, such as the "He's too op" which can be negated by the fact that the MC is from the future thus having more powerful options. I'd like to see some of these people complain about a barbarian with a stick losing to someone with a gun because that is basically what these people are doing, of course the barbarian is gonna lose. The second reason for a bad review is the "All filler, no plot" point of view. If some of these people spent even half a second reading the synopsis, they would know that their argument is invalid. The MC traveling back in time is not going to automatically go after some enemy since the world ended of natural causes I.E sun dying. If you were a time traveler from a future where you died because there was no resources, would you automatically blame a random person you see on the street for all of that? Of course not. These reviewers think this is full of filler because the author did not pull a ultimate world ending villain out of his but and say the world ended because of him. The MC does not have a overarching goal other than to be stronger for the sake of being stronger.I would consider the story at this point in time to feel more like a slice of life hence some of the bad reviews.
