Hi. I was just wondering if I could get some help? I forgot the title of a manhua I once read. It's about a girl who died of an illness and reincarnated into another world. There, she has to live and pretend to be a boy for various reasons. The manhua involves some martial arts, sci-fi, fantasy, and some technological advancements. her hair is short and born with a single braid on the side. She attends school and is frequently sent to different artificial worlds to train. Her dad died when she was born because of an ambush in one of his missions. There are mecha robots in the manhua. Please tell me if you have anything in mind or ask away for an additional description. I'd really appreciate your help guys. Ofhand this one is a Chinese manhua.
