After a long time, Lin Feng slowly closed the book and took a deep breath.
Perhaps because the middle-aged man in yellow clothes was only of silver rank, he didn't have a thorough understanding of this realm.
However, through some clues, Lin Feng confirmed Eldest Dou's words and found them to be mostly true.
Lin Feng looked into the storage bag and found a crystal slightly larger than the others.
"This is a second-rank beast crystal," Lin Feng muttered.
In this world, magical beasts were classified from the first to the ninth rank, corresponding to bronze to god rank. Beasts of the third rank, equivalent to golden rank, could already transform into human forms.
"In magical beasts, with each rank increase, the elemental energy contained in the crystal exceeds tenfold."
Lin Feng looked at the crystal in his hand, pondered for a moment, and began to absorb the energy to recover.
