She wondered what determined what came with a person and what didn't. Her own sword had showed up, the same as Zidian had for him. Which meant that it was possible for Sandu to show up, as well. Though, she wasn't overly worried. So, the question has her giving a soft smile.

"No, A-Cheng, not worried. My sword showed up and I was going to have you and A-Xian help me train. So that I have a way to protect myself if need be." Not that she thinks she'll need it, but it would probably put the mind of her brothers at ease, especially if she learns how to properly use her sword.
