After multiple experiments conducted by Tang Wanwan, it was confirmed that there were four general herbs in the poison, with only one very important component called Crimson Grass. This grass has a significant characteristic: it prefers soil with acidic growth conditions. Tang Wanwan remembered that red soil is acidic, but whether this grass is present or not needs to be confirmed through medical texts.
Tang Xiao Yi and Han'er, being children, found nothing more entertaining after the bones were steamed to kill the ants. Brother Lu and her sister were both in the room studying medical texts, and the two little ones were also yawning. Hearing their yawns, Tang Wanwan realized the two little guys were tired.
They surprisingly were not afraid, watching with great interest. Tang Wanwan explained to Tang Xiao Yi that to find the specific source of the poison, one must keep experimenting and then verify each result. Tang Xiao Yi nodded earnestly, remembering everything.
