Just as everyone was wondering about what's happening with the servant lady, the painting separated from the real world and shrank back into the hands of the old man.
With a wide smile, the old man muttered a spell and released the servant lady who was stuck inside the painting.
"I hope, you all understand the use of this 'ethereal canvas of entrapment.' It can trap any organism under the Grand Master Magus stage permanently. As per mortal sovereigns, it can hold them inside for seven days. In the case of Supreme Magus, it can mostly last for an hour.
But this artifact loses its effect with usage. You need the help of a person who can do space engravings for regular maintenance. I hope I explained everything about this precious painting. Let's move onto the bidding process."
The old man walked back, letting Jia handle the rest of the bidding process.
