The obscure and difficult-to-understand beast race language became easily decipherable to Jacob.
As he delved deeper into the texts, his astonishment intensified.
Without realizing it, Jacob began to practice the technique with one hand while holding the ancient book with the other.
He waved his palm gently, and afterimages appeared instantaneously.
Immediately afterward, streaks of light began to flicker on the ancient book and flowed into Jacob's mind. Those streaks of light morphed into a human figure cultivating various palm techniques.
At that sight, Jacob began to flip through the pages more rapidly. As he did so, the figure in his mind moved faster and faster.
In the end, Jacob managed to use a very short period to finish reading the thick ancient book.
