Chen Fan had decided to stay a few more days in Lin City not only because he wanted to spend more time with Lu Yanxue, but also to wait for his assistance from Medicine God Valley Sect and Tong Shan. Previously, in order to get to Lu Yanxue and save her, he had left the others behind, allowing them to arrive in the city at their own pace.
Although Chen Fan had already mastered the Yi Wood Spirit Qi which he used to substitute the Essence Enhancing Pill, the Yi Wood Spirit Qi's function was limited. In addition to curing mortal's ailments, the Yi Wood Spirit Qi could also be used to increase the growth of Spirit Medicine.
Even a small blade of grass could grow into an astonishing divine medicine, much less those thousand-year-old rare herbs inside the vault of the Medicine God Vally Sect. The vault kept numerous ingredients for Spirit Medicine such as the Spirit Beast Fruit.
