Xiao Changyi also thought the same and, upon hearing An Jing say this, he lightly responded, "Mm."
Since Miss Yan Yao wouldn't say who her enemy was, they could try to investigate it themselves.

After inquiring in various places, Meng Zhuqing came back with some news two days later.
Then, Meng Zhuqing came to report to An Jing and Xiao Changyi.
Upon seeing Meng Zhuqing, An Jing smiled and said, "It seems you've found some leads."
Meng Zhuqing replied truthfully, "That night, besides the Fifth Prince's Mansion, Duke Tao's family also had quite a stir, which just happened to be witnessed by a night watchman. The watchman said, as he was passing by Minister Tao's residence on his rounds, he saw a person dressed in black rushing out from Tao Shangran's home. Immediately after, he saw several Protectors from Tao Shangran's family giving chase, heading south of the city after the person in black."
