The medicinal herbs found on the winter mountain were not plentiful, but those that could be found were exactly what Doctor Du needed, and with each new discovery, Doctor Du was very happy.
Mo Yan didn't recognize every kind of herb, so Doctor Du would dig and simultaneously teach Mo Yan about the growing habits, medicinal effects, and properties of each plant in detail. For the herbs whose effects he did not fully understand, he encouraged Mo Yan to explore on her own.
Mo Yan learned with great diligence. As Doctor Du explained each herb, she carefully memorized it in her head, hence she followed Doctor Du closely along the way, completely ignoring the eager Xiao Ruiyuan who had followed them.
Being able to see Mo Yan, even if he couldn't talk much and even with a third person present, Xiao Ruiyuan was very content. He showed no sign of impatience and occasionally would ask Doctor Du a few questions about the herbs.
