The study was extremely quiet, with a thick Persian carpet laid out on the floor. Lin Baici stepped on it without making a sound.
He dug his fingers into the crack.
"Could this be where you insert the coins?"
Lin Baici slowly turned the dial, and after three rotations, a polite voice suddenly came through the phone.
"Please insert coins to use!"
"What coins? Money?"
Lin Baici immediately asked.
"Please insert coins to use!"
The other party did not answer. After repeating this sentence three times, the phone hung up.
Lin Baici immediately began searching the room, rummaging through everything to find coins from this era.
He didn't even know how many would be needed?
After searching around, he turned over all the cabinets but didn't see a single copper plate. There was no choice but to move to the next room.
There was no one visible in this ancient castle; otherwise, he could have just taken it directly.
