I am looking for good light/web novel with a good plot, preferred alternate or fantasy setting with technological advancement. I am sick of god level destructions in chinese novels where attacks are described as heaven and earth shattering tho I prefer their story style. something which are realistic, some people complain technological advancement to be too fast in some novels but i prefer in a good phase not too slow not too fast. Avoid level system, dungeons and labyrinths, little to no involvement of gods. romance should be not meaningless where a girl just falls in love without a plot behind. I enjoyed novels like Release that Witch, isekai tensei soudouki, kanna no kanna, common sense of a duke's daughter, Youjo Senki, manga like Dr. stone, gate, combatants will be sent, Manuke FPS(if labyrinths are skipped). I am sick of wimpy jap novels where killing a person for his own survival takes a toll on him, also avoid meaningless killing.
Tensei Shitara Slime Datta Ken (WN) is a good read and the anime is currently airing. If you have access to LN, go for it. Manga is good but it isn't the best choice to read due to where it is atm. Maybe after the big arc is finished, I'll recommend the manga.
Maouyuu Maou Yuusha Densetsu no Yuusha no Densetsu Toaru Majutsu no Index Tenkyou no Alderamin Heavy Object Yuusha Gojo Kumiai (manga)
Heavy Object Mahouka Koukou no Rettosei since u asked light novel with alternate reality and tech advancement....
Mahouka Koukou no Rettosei since you enjoyed combatants will be dispatched then try Kono Subarashii Sekai ni Shukufuku o! its from the same author.
