I'd like recs for fantasy historical reincarnation novels where MC is born into less than ideal circumstances, a neglected, abandoned, orphaned, poverty etc who despite difficult conditions rises above it using past life knowledge, to escape their situation. If possible a business but happy for tech advancements orientated one would be great a non modern world, no smut, I don't care about romance pref so long as it isn't harem. Can be manga/webtoon/novel etc Examples Modern man in a murim world Release that Witch (minus harem) Running Away From The Hero Reborn Rich Dr stone Ascendance of the bookworm The greatest estate developer Isn’t Being A Wicked Woman Much Better?
Ascendance of a Bookworm, maybe? Spoiler reincarnated MC, poor family. MC's original person was born w/ excessive mana that if not regulated would make her sick & in a long run would definitely killed her (which also the probable why the original person died). Those w/ such condition aren't rare & the "cure" (if you could call it that) is to pour their excess mana into artifacts (not specified what those artifacts are, but in short they became "batteries" for it), unfortunately those who own such things are the rich & the church
It is not exactly what you described but have you tried https://www.novelupdates.com/series/cultural-invasion-in-different-world/ The closest I can think of to what you described is https://www.novelupdates.com/series/the-founder-of-the-great-financial-family/ but I must admit I gave it up quite quickly because I thought the MC was an idiot.
Lady Su's Revenge is a rollercoaster for sure. I have recommended this novel multiple times but each time I have to give a warning. The beginning might seem lackluster, but it picks up almost immediately after a tradegy happens. And you may feel the ending is a little.. meh. Still 4.5/5
