This skill wasn't discovered until after the New Year.
She was pretty panicked at the time and hadn't had a chance to tell Grandpa Jiang when Wei Jincheng said, "This place might be like its own world, and it could change with time."
Perhaps the changes here were more magical, somewhat like the martial arts novels he had read.
Xue Jianian didn't know anything about martial arts stories; to her, the space itself was a marvelous thing, so other functionalities wouldn't be surprising.
Of course, to her, it wasn't surprising, but if someone else knew, even Lu Jingqiu, whom she considered quite clever, would probably be shocked.
Xue Jianian didn't know that if Lu Jingqiu heard her thoughts, she would definitely laugh out loud; these kinds of spaces were very common in future novels.
She would have been surprised to encounter a local with such a space, as in the novels she read, people like her, travelers through time, were equipped with a golden finger.
