I want to read a story about the mc transmigrating into a member of nobility or royalty's body. Like, Trash of the Count's Family, Little Tyrant Doesn't Want to Meet a Bad End, Solo Bug Player, How to Live as the Enemy Prince or Trash of a Fantasy Novel. I also read that one with Death Flags in the title btw, so this is just an idea of what I'm looking for. I prefer male protagonists, and no BL or harems. Xianxia/Wuxia is fine, and so are mangas.
you already listed everything that i read oh well how about : Isekai Tensei Soudouki I’m the Evil Lord of an Intergalactic Empire! never die extra ( i dont like this one but maybe you will)
MC is transmigrate to body of dead ancestor duke of kingdom 800 years dead. Kinda interesting seeing how people react to ancestor coming out of grave. Kingdom building. https://www.novelupdates.com/series/sword-of-daybreaker/
