Humming a tune, Ling Ping'an walked among the bookshelves.
He walked straight to the end of the row of bookshelves that leaned against the wall.
Ling Ping'an brought a small stool and stepped on it. He stood on Tiptoe and found a large book that was sealed with hardcover paper at the top of the bookshelf.
"Hmm..." He took the thick book down from the bookshelf, blew on the dust, and praised, "The quality of old books is so good!"
This book had been in this bookstore since Ling Ping'an's grandfather's time.
There was a reason why it hadn't been sold for so many years.
The first reason was that this book was extremely unfriendly to most people!
It was written in Classical Chinese.
Secondly, the things in this book were too obscure and difficult to understand for most people.
Anyway, Ling Ping'an chose to give up after reading it twice.
