After the disguise was done, it wasn't long before Zhang San heard someone say, "Mr. Zhang San, we've come to bring you your meal."
Upon hearing this form of address, Zhang San knew that the other party was being very courteous to him.
From this, it must surely be a feast.
Thus, Zhang San hid behind the door, letting Hei, who was disguised as him, wait in the center of the room for the door to open.
Then...
One could see a food box being lowered down through the skylight by a rope.
"Mr. Zhang San, this is your lunch. If there's anything else you need, please feel free to let us know."
Seeing that the lunch was actually being lowered from above, Zhang San was completely baffled.
How lazy can you get?
Can't you even open the door to deliver a meal?
Lazy!
Too lazy!
But Zhang San was also helpless, after all, since the other side didn't open the door, he couldn't ask.
Otherwise, it would reveal his intention of wanting to escape.
