The butler, upon hearing this, did not dare to delay and immediately went to retrieve the surveillance tape...
In the Blue Mountain Villa, there actually was a very complete surveillance system, but when it was first being installed, Ou Mucen, who lived in Orchid Garden, did not like his privacy being invaded and thus refused its installation.
What he didn't know, however, was that although he had refused, for many years now, the old man had still secretly installed a few hidden cameras around his garden, and what the butler was fetching now was the footage captured by those cameras.
The surveillance tape was quickly brought in, and the old man, upon seeing it, went to the study and asked the butler to insert the tape into the computer.
Indeed, once the tape was inserted, a blurry image soon appeared on the screen.
"Master, it seems quite unclear, it looks like we should replace this camera," the butler also realized and hurriedly fetched his master's reading glasses.
