The missing key elixir recipe information in "Apothecary Seven Chapters" in his hand made Lu Xuan feel a momentary vulnerability that he couldn't help but curse the Primordial Infant True Monarch behind it.
However, he also understood that this was very likely an effect of the light cluster rewards. He had had similar experiences before, where he needed to open several reward clusters to piece together cultivation techniques, puppets, and other items.
"I guess I'll have to wait until the Medicinal Pangolin advances to fifth rank before I can get the latter part of the 'Apothecary Seven Chapters' from the light cluster rewards."
Lu Xuan thought to himself.
However, even just the first three chapters are extremely useful for him.
They allow him to better understand alchemy knowledge, while also allowing him to infer the necessary spiritual plants based on elixir information and plant properties. This way, he can purposefully receive rewards from light clusters.
