Consolidating the corporeity was a long process. It was unknown how long it would take for the herbs to take effect. So, treating Zhou Xiong's son was an opportunity for Wang Yao to test his knowledge and ability and observe the effect of his herbs. Of course, the child's health would always be his priority. Even if the child could not be cured completely, Wang Yao was determined to improve his health.
Wang Yao worked until the mid of the night without having dinner. He had written down everything he could think of.
I can put all the cases like this together and even write a book for other practitioners to read, thought Wang Yao.
The ancient Chinese herbal books were also classified summaries from ancient Chinese Traditional Medical Practitioners. But, Wang Yao had been using licorice roots, which were rare herbs and only could be obtained from Nanshan hill. Therefore, his classified summary might not be useful to other practitioners.
