After leaving the palace, Lu Hetian did not return to the Grand Duke Mansion directly and instead took a detour to Cathay Medicinal Shop.
There were currently a few patients in the shop, and Ling Lihua was treating them.
Wu Hongming was assisting her from the side.
Although he did not possess any medical skills, after spending so many years by her side, he had come to memorize the uses of several medicinal materials by heart.
Therefore, he could at least fill prescriptions for the patients.
During the same period, the old beggar and Youyou had also learned to identify medicinal materials, so there were now three people in the medicinal shop who could fill prescriptions. With the three of them working together for that, they could even handle large numbers of patients.
Just then, Wu Hongming noticed Lu Hetian standing outside the door.
