I was lost in thought, but the fat man looked at me in a daze, so he pulled the paper away, and as soon as he looked at it, he shouted: "Professor Wang, can't you?" After saying that, he looked at the old man doubtfully.

I woke up from my daze and looked at the old man with suspicion.

"Yes, he is your professor. If he doesn't know it, I really can't think of anyone else who knows it. He is a true expert in this field." The old man said seriously.

"Why haven't I heard you say that you know our professor before?" I was about to ask, but the fat man had already asked first.

"Haha, we know each other? We have been old friends for decades. Who among the older generation in the antique world doesn't know him? I have been friends with him for decades." The old man said with a smile.

The fat man and I opened our mouths in astonishment. Neither of us expected that the old man was actually friends with our professor and had been friends for decades.

"Haha, you don't know that there are a lot of things. Go and ask him. I have other things to do these two days. I'll leave right away. You can just go by yourself." After saying that, the old man got up and walked out of the counter and walked to the next door.

I walked to another store, that store also belonged to Fatty.

I didn't expect that the old man would ask me to ask Professor Wang. I really didn't want to go, I didn't want to face him again, I had let him down...

The fat man turned on the copier next to him and prepared to make a copy of the book. He couldn't take out the original book every time he read it, right? If that were the case, this valuable ancient book would have been destroyed long ago.

"Ask?" The fat man closed the cover of the copier and prepared to start copying.

I gritted my teeth and said, "If you ask... you have to figure it out." It seemed that curiosity prevailed. I really didn't know what to say when I met the professor, but in order to figure it out, there was no other way.

I have been very interested in these things since I was a child. Ever since I was a child, I have tried to do my best in anything that interests me.

"Huh? The copy machine is broken?" The fat man shouted strangely while holding a copy of the ancient book that had just come out of the copy machine.

"No way, this is an imported copier that I just bought. Why did it break down so quickly?" I stepped forward to take a look.

The fat man was holding the three pieces of paper that had just come out. I took them and looked at them: "Huh? Yes, why is there a blank space?" I also felt strange.

What was copied on the paper was the main text of the ancient book, but within a large pile of words there was a square blank area, the size of two fingernails, covering exactly three lines, and each line covered three words.

, the top, middle and bottom are nine characters in total.

"No way? This is a copier I just bought. Even if it breaks, it won't be broken in such a neat way." I asked myself doubtfully.

I continued to scroll down, and this time it was even more strange: the same was true on another piece of paper. If the copy machine was broken, it would not be strange to have such blank spaces on other papers. What was strange was that the other piece of paper had such blank spaces.
