Roland didn't wait for long; after a few hours, he heard faint noises coming from inside the house. Considering the secret door was originally in the storage room, the fact that he could still hear faint noises after multiple barriers was a testament to his exceptional hearing.
However, he wasn't sure exactly who was inside the house, so he didn't knock immediately but waited a little longer.
After a while, when he was certain there was only one person in the house, he took out his revolver and knocked on the secret door above with the gun handle, creating some noise.
