These are still the thinner books, but if it's a hand-copied, thicker one, they can sell for up to sixty silver coins each.

Xue Yan pocketed the fifty coins and tucked them into his chest.

Those fifty coins were, of course, pure profit. Since the bookstore provided the ink, brush, and paper, all he had to do was take them home and copy them.

Seeing Xue Yan planning to also take the ink and paper provided by the bookstore, apparently still intending to copy books to sell, Jiang Yue lowered her voice and said, "You better not copy any more, this thing is bad for your eyes, and we're not short on money anymore. If we need money, we can always make some other crafts to sell to Manager Qiao."

Xue Yan looked at her and saw that she truly did not want him to keep copying, so he gave up on the idea.

Indeed, they were no longer short on money.

"Then let's buy some earth paper, as you wanted to make a fire piston, right?" Xue Yan suggested. Earth paper was needed to make fire pistons.
