[Genshin] I Woke up at Night and Became My Younger Sister in One Second.

Hello everyone, my name is A Qing. Yes, you read it right. I was originally a dying person. One second I was rescuing me in the operating room. The next second I opened my eyes, I saw a handsome and burly guy with well-developed chest muscles in front of me. I thought it was a wonderful introduction to love, Then he said he was my dad. I was thrown into the village as unqualified and adopted by a family leader with the surname Niwa, and then I lived a life of hammering with iron every day. Everyday I make iron, eat, and scold my dad, which is simple and happy. It wasn't until the dark tide hit later that I opened my eyes again, and there was a boy who looked exactly like me sitting in front of me. Just when I was wondering if my father had given birth to another child, the boy told the strange man next to me that he was my brother. I:. Just woke up a second late, and this brat is on top of me? ! When I was born, you were still a bud in the tree! No, I have to be the sister! I can't let this brat who looks like me crush me! 1.
