The formation of the class advancement book indeed surprised Zhang Xuan.
It was indeed unexpected for Zhang Xuan. Only when one reached their peak strength could a class advancement book appear.
Moreover, it still required defeat!
After understanding this, Zhang Xuan was a little puzzled and curious.
"Dean, will class advancement players also be like this?"
Zhang Xuan asked. If the Abyss Leader was already like this, the class advancement players shouldn't be bad either.
After all, when he changed his profession, Zhang Xuan clearly saw that the Abyss Necromancer, Elix, was a proper human.
In other words, there were more than just monsters in the abyss.
There were also humans, but they had the abyss label on their bodies, or perhaps their bloodlines came from the abyss.
In the face of Zhang Xuan's question, Chen Yin was clearly stunned.
