Review Detail of Not_SkeleBlade in Immortality: My Spell Upgrades Infinitely

TLDR; Boring, some grips of plot, bad-harem, sudden love, MC does a terrible job at utilizing his cheat and getting stronger in favor of saving the damsel Read up to chapter 38, got bored of the story and could at least read up to the latest 40 chapters. The story premise is interesting, but aside from the intial couple of chapters, the premise was thrown to the side for the harem route. There is harem in this story, and by 38, there are about 4 women who are in the harem, while 2 are possible. This isn't even a good harem as the women kind of just fall in love with the MC out of nowhere. The biggest issue I have is that the author introduces the little sister character to be cute, the MC kind of just likes her in the first meeting, but, and this is a spoiler, kills the girl, turning her into a ghost where the MC marries her to keep her life? (Undead Life?) The MC spends more time chasing skirts than getting stronger, although I wouldn't consider him a pervert like harem-seeker, more of a guy who likes women and due to plot armor they like him back. I would say this story is only good for those who lack other better reads.
