This Flesh Sac Secret Chamber was strange.
The surrounding flesh walls were filled with mouths and the mouths were open, revealing tightly clenched white teeth.
Not only this, these mouths were even letting out strange laughters, making one shiver all over.
Fang Yuan patted Bai Ning Bing's shoulder: "This is the effect of flesh laughter Gu, it is just like Earth Treasury flower, and is used to store Gu worms. No need to worry too much."
He had just finished saying this, when suddenly the teeth completely fell off from an open mouth and a scarlet tongue extended from the mouth.
The tongue was very long, about over a meter, and the front part was curled up.
When the tongue fully extended, the tip of the tongue started straightening and revealed a book on it.
This was a bone book too, except it was many times smaller than the Grey-Bone Huge Book; pocket-sized, about half of an adult's palm.
