"Why can Xue'er visit though?" Yang Wanqing asked.
Yang Zhenshan stretched his hand and gently tousled her hair bun, smiling, "Although you call her sister, you must not really treat her as one. She might even be older than your mother!"
Yang Wanqing stared blankly at Yang Zhenshan, somewhat doubting whether he was talking nonsense.
"She is the Palace Master of Snow Spirit Palace! Her cultivation technique is quite special. Though she appears young, she is actually much older than you," Yang Zhenshan explained.
The first time he met Xue Qiaoer, he really thought she was a sixteen or seventeen-year-old girl, but now having met her again, he understood that Xue Qiaoer was not a sixteen or seventeen-year-old girl at all.
Yang Zhenshan guessed that Xue Qiaoer might be in her twenties or thirties, and the possibility of her being any older was not very likely.
Even if the cultivation techniques of Snow Spirit Palace were special, they wouldn't make one eternally young.
