It was at this moment that a familiar voice rang out from a distance, "How is it? Marquis of Guanjun, have you figured anything out?"
Li Xuan turned his head and saw that it was indeed Zuo Daoxing, the Dudu Tongzhi from Xiuyiwei, who was hurriedly flying in from a distance.
Li Xuan was not surprised. The case of the Crown Prince's sudden illness was so significant that it would be strange if this man wasn't alarmed.
But at this moment, all Li Xuan could do was shake his head, "It's highly suspicious, but we lack definitive evidence. I've had people check whether the three deaths due to brain tumors are connected to the two foreign monks and these black datura flowers. We also need to check if there are any other cases of brain tumors in the vicinity. The black datura flowers should also be taken back for the Imperial Physicians to examine."
Li Xuan then asked, "Did your search yield any results?"
