Book of Elfins

Math had always been Zhang Zian's worst subject. He felt a bit lost as Meng Li's question came from nowhere. "What do you mean?"

Meng Li looked at his watch, and said in a hurry, "If you want to look for a book about life, universe, and everything, maybe try to search in the reference book section. If that kind of book exists, it should be classified as a reference book. I need to go. See you soon!"　　

Before Zhang Zian could respond, Meng Li waved and hurried off with his books.　　

"Wait! Why reference books?"　　

By the time Zhang Zian finally processed the information, and hurried off to the second floor to ask for an explanation, Meng Li was already at the check-out counter, then disappeared in the blink of an eye, leaving Zhang Zian lost.　　

Meng Li spoke with a certainty. Although how life, the universe, and everything could be considered as a reference books, he didn't know, but he didn't have time for a random search. The reference section seemed to be his only option.
