Lin Qiang made a hushing gesture to him, and after examining the door, he realized it had been secured from the inside; it would probably take some effort to force it open.
If they were to jump into the courtyard from the doorway, they might make a noise and alert Lin Xia and the others.
Lin Qiang then moved to the window and noticed that there was a lock beneath the shutter.
"Brute!" Lin Qiang gestured to him in a low voice, "Open it!"
The two had come prepared with tools and, after a lot of careful effort, finally managed to pry open the lock.
Once the shutter was removed, dealing with the tightly closed window was much simpler.
The two divided the labor: Brute kept watch outside while Lin Qiang went in to search for anything valuable.
Wielding a flashlight, Lin Qiang searched around the room; aside from a stack of finished clothes and two bolts of fabric, there were just sewing machines and edging machines.
