After Avery pressed his hand down on the mural, a light sound came from the bedroom wall.
There was no doubt that there was a secret chamber behind the wall. This light sound was the sound of the secret door on the wall opening.
Gustave, who was sitting in front of the French window, stood up and his expression suddenly changed. He walked a few steps over to stop Avery.
"Mr. Gallard, you're also a businessman. You should know that the secret chamber in a businessman's house is a bottom line that cannot be touched. There are confidential documents placed there.
"Before you press this switch, you have to think clearly. Once you break into the secret chamber, the Walpole family and the Gallard family will no longer be friends."
Avery's hand was still on the mural, but he did not press the switch immediately. "Don't worry, I won't look at any documents. I will go in and confirm that there is no one inside. I will leave immediately."
