Chen Yuan did not expect that he would get a system. It's also a 'humanized' system that sells books and uses intelligence to deal with them if they can't sell. However, he never thought that books could also lead to enlightenment. The book has its own golden house, the book has its own beauty like jade, three hundred and sixty lines of music, chess, calligraphy, painting, poetry, wine and tea, and all kinds of books are in hand. Who in the world does not recognize me?
