Gu Mian was still observing when he heard noises coming from the bookshelves behind him.
He turned around and saw a face that he was sorry to look at peeking out from the bookshelves.
Gu Mian had just wanted to wonder how there could be such an ugly ghost when he saw another big face appear closely next to the ghostly one.
Oh, it turns out the first one is Xiao Hong.
"How did you guys get up here?" Gu Mian originally wanted to confirm the area was safe before calling them over, but he didn't expect that after being up there for just a couple of minutes, he'd see these two familiar faces.
Fatty was helping Xiao Hong put back her fallen face cover while saying, "Doctor, after you came up, Xiao Hong was crying and insisting on coming up too, and seeing her come up, I followed. Doctor, what is this place? Have you figured it out?"
