"This should be the place." Jiang Yue pointed at the wooden board.
Xue Yan nodded. He also felt that there should be something under this wooden board.
This wooden board could only be discovered when the shelf was moved away. Moving the shelf would make a noise. The shelf was adjacent to this wall, so the next door could hear it.
Since it was confirmed that it was under this piece of wood, then this piece of wood had to be moved. Jiang Yue and Xue Yan casually lifted it and moved it to the side.
Then, about ten centimeters inside, an iron plate was revealed. The iron plate had a lock on it. Only by opening the lock could the iron plate be pushed in.
"It should be one of these three keys." As Jiang Yue spoke, she pressed the size of the lock and tried one of the two big keys first. If it didn't open, she tried the other big key and it opened with a click.
