The notebook was brand new, but now Xiaoxu had written a few pages in it.
After a while, Xiaoxu finished writing, flipped the notebook over, and showed it to Su Xingyue.
...
—I went out for a while, but no one noticed me.
...
Looking at the words on the notebook, Su Xingyue couldn't help but feel puzzled.
"Where did you go?"
Xiaoxu put down the notebook and pen, walked to the bed, and took a metallic object from under the bed's headboard, handing it to Su Xingyue.
Su Xingyue took the item and, upon closer inspection, realized it was a small harmonica.
Did she go out just to get this?
"Is this yours?" Su Xingyue asked Xiaoxu, unable to resist her curiosity.
Xiaoxu nodded.
"Then... are you familiar with this place?" Seeing this, Su Xingyue couldn't help but ask curiously again.
Xiaoxu seemed quite familiar with this ancient castle.
Moreover, she always felt that Xiaoxu must have some connection with the owner of the castle.
