"What is that?"
Upon hearing Fox Fairy Nannan's words, Zhang Chen quickly turned his head and saw Fox Fairy Nannan standing before the Crystal Bone, shouting excitedly at Zhang Chen.
"Come and see! You'll understand after you look!" Fox Fairy Nannan said urgently, "This is the Supreme Celestial Book!"
Hearing this, Zhang Chen hurriedly approached to take a look, standing beside Fox Fairy Nannan, and followed her gaze to the bluestone in front of the Crystal Bone.
The Crystal Bone was sitting on the ground, with a book placed in front of it. However, because the color of the book was too similar to the bluestone, and due to the dim and unclear firelight in the stone chamber, the jade bone had attracted all of their attention, so they hadn't noticed the book placed on the ground.
Moreover, the book was very thin, less than 0.3 centimeters, currently laying open quietly in front of the jade bone.
