Chu Yi took the book from Fu Bo's hand, opened it, and his eyes immediately widened.
Was this even a book?
It was merely a book with a cover; beneath the cover lay a Spirit Stone.
This Spirit Stone appeared to be uncarved.
Yet, it was as if carved by a skilled craftsman, with all sides very smooth and flat, and the surface also quite sleek, shrouded with a very dense Spiritual Energy.
Both Chu Yi and Tang Wan involuntarily exchanged glances.
Chu Yi saw the corners of Tang Wan's lips curl up slightly.
It was obvious she was very pleased with the Spirit Stone.
Fu Bo explained to Chu Yi:
"From the first glance I took at you, I noticed that your Spiritual Energy was a little less than ours."
"To be honest, in our Bale Mountain, aside from the Monster Beasts which are considered hard currency, there are also these Spirit Stones."
Tang Wan couldn't help but take it from Fu Bo's hand and scrutinize it closely under her eyelid.
