Old Tang was momentarily stunned and quickly flipped backward through the pages; indeed, the content he had skimmed with his skill was thoroughly understood. He could describe it all in his own words after a single glance.
This skill was really not so simple after all!
No, he needed to stay calm. Old Tang quickly flipped forward again. He wanted to see what the content he had previously read was like.
Perhaps it was because he had deeply understood the latter content that by association, his understanding of the earlier content had also deepened significantly, though he didn't quite have the feeling of complete mastery yet.
If so, this skill was a bit overpowered since it implied that his learning of new knowledge would reach an unprecedented level.
Although there wasn't much time now—ten minutes wasn't enough to read much material—little by little, Old Tang had a premonition that gradually, he would be able to persist for even longer.
