"Practically impossible."
Shan Dongchuan led everyone to a large vase at the corner, tapped it lightly twice, then twisted the vase slightly and tapped it again twice. Immediately, there was a rumbling sound and the secret chamber's stone door closed.
The stone door blended seamlessly with the surrounding walls, making it difficult to notice unless one looked closely.
Shan Dongchuan said, "Jin Ao making his first visit to Mengyao Pavilion could not possibly be so familiar with the mechanisms of the secret chamber."
Ran Qingchen observed the mechanism carefully with a slight frown.
It was all too coincidental that the secret chamber door malfunctioned at a critical moment.
