John didn't explain any further. They would know everything soon enough in class.
After passing several buildings, Qin Guan and Cong Nianwei finally reached their favorite place: the library. The building was of a solemn, ancient style, unlike the rest of New York, which was very fancy. Human knowledge was stored there.
The library of the University of Columbia had the fifth largest collection of books in America. There were thousands of ancient books there. The floor and the chairs were made of brown wood, and there were also private, independent chambers. Students there had many choices.
Their class was a vocation course, yet half the seats were already taken. They made a quick visit to the library and then left.
"The library is open 23 hours a day. The staff arranges the returned books during that one hour. You can study here anytime."
