Casillas almost spat blood when he heard this.
He was an arch-magus. All the books he read were definitely high-level magic books.
The contents of the magic books.
They were all magic knowledge.
His magical knowledge far surpassed that of others, so of course, he could read and understand.
But it was totally different from understanding and knowing.
For example, if a person knew how to play table tennis, would he be able to compete with the champion?
That was not scientific!
Jack's words were clearly superficial.
Anyway,
He was the arch-magus.
How could he believe such a superficial statement?
However.
Seeing the indifferent look on Jack's face.
He didn't know how to refute it.
This guy was too weird.
Casillas had to take another look at Jack.
He fixed his eyes on the blade of space in Jack's hand.
Jack was still playing with the blade of space.
The aura had not diminished at all.
It was as if the blade of space was an extension of his life.
