Trigonotis peduncularis?
Pang Zihuang furrowed his brows. His eyes were full of suspicion. "What trigonotis peduncularis? We have never heard of such a thing!"
"Trigonotis peduncularis is a kind of poisonous herb. Generally, anyone who comes into contact with it will begin to experience its delayed poisonous effects. If my guess is correct, someone has recently presented Your Imperial Majesty with the plant as a gift. The plant had probably withered within three days, and Your Imperial Majesty has been experiencing acute headaches since then. Is this correct?"
Gu Ruoyun smiled gently, her eyes observing Pang Zihuang from the start. Upon hearing her words, Pang Zihuang’s face sank, and his eyes glazed over as if looking at a faraway landscape.
But he remained silent.
Because he would not speak, Gu Ruoyun did not press for a reply. All in all, even though Pang Zihuang was open-hearted, this matter was confidential and he would not expose any palatial matters to an outsider.
