My Brother Is a Sister-In-Law

Xia Yu: My name is Xia Yu, and I am the number one hero in S-class. But I have no interest in the profession of hero, nor do I have any dreams. The reason why I chose to be a hero was purely for the sake of my sister. Xia Xue: My name is Xia Xue. My dream is to be a hero. I have an older brother who is good for nothing except having money. He only knows how to eat, drink and have fun all day long. If his uncle and aunt hadn't spoiled him every day and gave him a million dollars a month, he would definitely be picking up rags now. Xia Yu: I didn't tell anyone that I was the number one hero, including my sister, because I kept a low profile. Xia Xue: It would be great if my brother was a powerful hero. Look at other people's brothers. . . Alas, forget it, stop talking, it's another bitter tear. This is a story about a careless rich brother carrying his sister on his back and wearing a red mecha to secretly save the world. It is similar to Iron Man, a man who spends money to become stronger, but much more powerful~ At the same time, this novel revolves around the beloved sister... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
