The messenger Zhou Huailing sent had already arrived, telling Gu Chaoyan that the Crown Prince was asking her to go into the court quickly.
The messenger did not tell her the real reason why she was asked to go into the court, other than that she was asked to go into the court soon. The messenger knew some of the details, but he just passed on what Zhou Huailing asked him to.
However, even though the messenger eunuch did not reveal anything, Gu Chaoyan more or less understood what she was called into the court for.
Zhao Dier had been poisoned for days.
Lingyun had never returned to Huaishi since she moved in, so they could obviously not get an antidote, but the pills from Piaomiao Pavilion were not drugs, and Piaomiao Pavilion would never be able to detoxify anyone. Piaomiao Pavilion did have some upper-grade pills, but none of them worked for this drug.
