It's a BG romance. The FL with special abilities was reborn in another girl's body. I think one of the special abilities is seeing through walls and stuff (not sure). The ML is from the military with a high-ranking position. And I remember the early parts of the novel is the ML trying to track the identity of the female lead. I think the FL did some massacre in some village or something? That's why the ML is trying to track her down. That's the only thing I can remember, I've read it years ago, and I dropped it since there are no further updates of translation.
I don’t know but I just read a post apocalyptic novel it’s okay it’s called Post-apocalyptic Cannon Fodder Pampered Everyday
