After Vincent bought the book, The Compendium of Beast: Third Edition, he was already quite familiar with the Savage Beasts and Magic Beasts that are existing in this world.
As a matter of fact, the compendium even includes the materials that can be looted from the bodies of these beasts. This made him aware of the value of the beasts that they were encountering from time to time.
However, there are Magic Beasts that are very difficult to find so compiling information about them is a hard task.
The White Tiger in front of him is one of them.
The information in the Compendium only states that this magic beast has an affinity to Lightning Element and is very difficult to tame unless you managed to train it when it is still a cub!
"Elder Han… I didn't know that your sect is also transporting this Magic Beast." Vincent commented after seeing the cub safely protected inside a white steel cage.
