The Yuanming Sect has a Spirit Mountain specifically for outsiders to rest, and Li Zhirui and his group have been staying there these days.
Compared to the other three who had already started alchemy, Li Zhirui was still deducing the Pill Recipe of the Water Refinement Pest Extermination Powder, with his progress unknown for how much slower it was.
Fortunately, because Li Zhirui hadn't applied for Spiritual Medicine for practice but was just holed up in his room, the people of the Yuanming Sect did not have much to say about it, although they did not have much hope for him either.
However, an alchemist with the surname Zhu from Yuanming Sect had already successfully refined the Insect-Extinguishing Powder. Although there wasn't enough to completely exterminate the black bugs, it effectively curbed the speed at which the black bugs devoured the Spiritual Objects.
