"I've been having Ye Yi investigate that person, but we haven't found any leads yet." Of course, he had thought of this too, and not only that, he had also investigated Prince Le's businesses.
"No, even if we investigate, we won't find anything. Who knows how deeply he's hidden?" Yang Chuxia pondered for a moment and then said, "Why don't we fight fire with fire? He likes to poison others, so we can also poison him. I don't believe that if the master is poisoned, the one who knows poison won't come out to save him. Let Mu Shaoling concoct some potent poison, and if it kills him, all the better; it'll be a clean finish."
Ye Zi'an chuckled lightly at her words, "Killing him with poison might be impossible, as someone who's been dealing with poison for a long time probably has some defenses against it. We can't target him directly, but we can target those around him. Using that opportunity, we should be able to find the one who knows poison."
