Due to the bookshelves blocking, the light in the secret room became even dimmer,
Li Ang discovered an arc-shaped track on the ground behind the left side of the bookshelf,
When the mechanism is activated, the left side of the bookshelf with pulleys installed would slide backward along the track, making the secret room appear—the bookshelf must move backward,
If it moves forward,
it will leave sliding marks on the study floor, exposing it easily.
"Watch my back."
Li Ang instructed Wang Congshan to stand at the secret room entrance with a gun,
while he turned his body sideways, held onto the edge of the bookshelf, and entered the secret room,
and used the Heart Monkey Staff to jam the mechanism, preventing the secret room from suddenly closing.
He turned around and saw on the wall of the secret room, a rectangular net woven with wire was nailed.
