After Nie Qianyu finished speaking, she led Zhang Xiaohua to the place where Huang Jing was planted. In the medicine field of one and two-year-old plants, she helped Zhang Xiaohua dig out a few Huang Jing plants and handed them to him, asking, "Brother Ren, these Huang Jing plants are not easy to wash. You hold onto them, and when we reach a place with water, I'll help you wash them."
Zhang Xiaohua was puzzled and blurted out, "Why do we need to wash them?"
However, he soon understood. Of course, Huichun Valley specializes in "decocting pills." If the Huang Jing plants were not cleaned thoroughly, an extra ingredient would end up in the Hunger Dispelling Pills. If someone discovered this, it would become a "mud pill," similar to the "injected water chicken" mentioned by Young Master Li Jinfeng.
