On the evening before Xiao'er and Shangguan Xuanyi's departure, the two of them took the children out from the Imperial City, then returned to Prince Rui's Mansion. After that, the children disappeared.
The next evening when they secretly departed, Shanggan Xuanyao, seeing only the two of them but not the children, couldn't help but ask curiously: "Where are the children?"
"They're not with us. I've entrusted them to a friend," Xiao'er casually replied.
Regardless of who asked, Xiao'er would always say that the children were entrusted to a friend!
For the sake of the children's safety, everyone wisely refrained from asking who exactly they were entrusted to.
Of course, this was just an excuse. The children were actually in a different space, under Bai Tian's care, though Bai Tian was also considered a friend.
