Okay!

Since the time Shui Xian learned about Raelle's siblings' professions, he had been in deep thought. It was in human nature to be curious. He was also itching to know more for some reason. 

He had jokingly said to her, "It seems your siblings are working hard to protect the country."

And she had replied him with, "We are also working hard for the country. Just because our battlefields are different doesn't mean we aren't fighting. They are trying to protect the country, we're working for its economy. How is it different?"

Shui Xian had nothing to say. He already knew that his wife took pride in her work. Or at least he'd define it as pride. But he also knew that she respected her ancestors a lot. And that is why army officers were actually not so displeasing to her eyes. 

It was also this fact that she had interacted with Zhai Yanjun normally even though he had offended her.
