Cultivation: Starting with Sterilizing My Own Father

The main character is a female protagonist who transmigrates into a male body! ... I'm saying it three times because it's important!!!
A woman who died due to a medical dispute is reincarnated. What?! She'll be a woman in ancient times? No way! Her family background and her parents' opinions are too much! She'll accumulate merit to be reborn as a man; in ancient times, men had a much higher survival rate than women.
What? The original body is ready and can't be withdrawn? Oh well, I'll just consider it as having another little sister.
What? The other person is the older sister? It's okay, it's okay.
The only cheat codes are an attribute panel and a personal storage space? Fortunately, Wei Zhiying has a Heavenly Spiritual Root, and her sister's homemade ones are not bad either.
"Mother hasn't been home for a long time, but she doesn't remember exactly where the house is."
Wei Zhiying looked at her mother, who was proficient in all the arts, including music, chess, calligraphy, and painting: "Even if I don't remember, I have to find her. Mother must be from a respectable family. If I work hard in my cultivation, I will definitely be able to help Mother find her home! But before that..."
Wei Zhiying sharpened her knife at her father, saying, "Dad, since you're not a man anyway, just cut it off. Once you're a father-in-law, you won't have any more worries."
"Little brother, we don't have a mother anymore... even though our mother just came home."
Wei Zhiying originally stayed with her sister, but gradually another person joined the siblings.
"Hello, I am Bai Zhaoye, pure and innocent, only the autumn moon shines on the wild man's garden."
Wei Lanyin looked at her younger brother, who was intently making a phoenix crown for her, and said, "I'm getting married."
Wei Zhiying took the phoenix crown to give to her sister, but froze when she saw the dagger plunged into her abdomen: "Brother-in-law..."
Seeing her sister crying in pain, Wei Zhiying collapsed straight down.
