After returning, Jun Yuyan rushed to tell the eager Murong Jiu what had happened in the palace.
From the Empress's reaction after waking up, their suspicion was correct; the Empress was aware of the Gu poisoning, indicating that Divine Doctor Miao was indeed working for the Second Prince.
The Empress was angry, but since she had already woken up and disrupted their plan, she took the opportunity to ask the Emperor, who was there by her side, to investigate who was trying to harm her by poisoning her.
The reason the Empress did not mention Gu, but rather poisoning, was to avoid making the Emperor suspect Divine Doctor Miao.
The Emperor's expression naturally wasn't very pleasant, and upon preliminary investigation, it was discovered that Aunt Bi Xiang had been acting suspiciously in the past few days, often sending other palace maids away and being alone, making her the prime suspect.
