After ensuring their attitudes were proper, Ma Lin walked into the room, first taking a prepared cloth to blindfold the little girl, then instructed the two people outside, saying, "I'm going to close the door now, no matter what happens inside, you must not peek. If you peek, it'll render it ineffective."
The man said, "You won't harm my daughter, will you?"
"Absolutely not."
"Don't try to do anything strange. If you can't do it, then don't try at all."
Ma Lin began to smile, saying, "Remember, you are the ones who invited me here."
The woman said, "Young man, sorry for making you come all this way. I can pay you five hundred yuan, and you can go back. We've decided not to proceed with the treatment."
Ma Lin said, "That's not necessary. I can just return like this, as long as you keep the painting on the wall and this Array on the ground untouched for a full day, you can erase it tomorrow at this time. I'm sorry for the inconvenience."
