Learning the medicinal book (1)

Time passed day by day, and in the blink of an eye, a month had passed. In this month, little crane grass had learned quite well. He had already learned the entire book of the Liu family's rules, and was now studying other books. The Liu family School had quite a large collection of books. These books were all carved and printed by the Liu family with their own money, and it would be extremely expensive to sell these books outside.

Because little crane grass's learning speed was extremely fast, Yu Shu and Yu Feng had already started to teach little crane grass individually. Because even the people in the large class weren't as fast as little crane grass in learning, they could only teach little crane grass individually.

Today, when school was over, it was still the old man who came to pick up little crane grass. However, unlike before, the old man was smiling more than usual.
