Fang Zhengzhi suddenly had a feeling that perhaps, his journey in the Holy Region this time would be a little harder than he had imagined. Without thinking about it too much, Fang Zhengzhi continued browsing through the books.
After ploughing through all the books on the sixth floor, he proceeded to the five floor but did not flip through each book with the same amount of detail. He merely perused the synopsis and content page of each book briefly.
Time sped past, and when the moon rose slowly above the horizon and the stars began to shine, Fang Zhengzhi has reached the first floor. Within these four hours, he never actually completed any single book.
Instead, he was synthesizing everything that he browsed through. In his mind, he synthesized and categorized everything he read from the first floor to the sixth floor before sieving out the important bits.
