"No, I just came." I followed him into the house, which smelled of books. I looked at the books in the room, the room was not large, it was full of bookshelves, and in the middle of the bookshelf was a table, and the floor was full of books on the top of the table and behind the table all the way to the window. It's a little cluttered.

"As soon as the new surgical building is built, I should retire. In the past few years, the dean has seen that my old man is old, and he has arranged this idle position for me, which is no younger than you. That, Little Dream Doctor, what book are you looking for? ”

I'm reminded of the diagnostics page: 300.

I asked, "Master Zhou, do we have a numbered book?" ”

Master Zhou said: "It turned out that there was, but the conditions of the hospital were not very good before, and there was no complete library, but there was a library in the old internal medicine building. Most of the books here were moved from there, many of them were rotten, and some of them are still there. So a lot of the numbers are incomplete.

"Is the number 300 book still there?" I asked.

The master surnamed Zhou shook his body and stared back at me, "Several people have looked for this number." There is no such book here. His lips moved a few times, "Little Dream Doctor, this book is estimated to be no longer available." You better not look for it. Find another book to read. ”

I felt strange and asked, "Master Zhou, are there several people looking for this book?" ”

That week, the master looked at the sunlight outside the window and said, "I know five people who have looked for this book." It seems that you have the most internal medicine departments. But," he shut his mouth and didn't continue.

"What's wrong? What happened? I asked.

"These five are young doctors, about your age. But they all died. ”

Sizzle!

"What kind of book is this?" I asked again.

"I haven't seen it. I guess it will be possible to find it in the library of the old internal medicine building. Doctor Xiaomeng, don't look for it, things in this world can be said to be very coincidental, and it can be said to be very evil. Some things are better not to get to the bottom of things. ”

"Did we register the serial number of the books in the original library? I wonder what kind of book it is. I asked, shocked.

"There's a directory. I'll find you. ”

Master Zhou walked to the table, opened the drawer and rummaged through it, and after a while, handed me a blue bound book. It looks like it's a register from my parents' time.

I flipped through the register and searched for it by serial number. The font of the fountain pen has faded a lot because of the age, but I can still see it clearly, and I found the book with serial number 300 in a moment's shock, which is a common book: On Mass Hysteria.

Mass hysteria? Hysteria is just one type of psychosis, also known as hysteria, and is a more common type of psychosis that is often caused by mental factors or undesirable cues. There is no basis for organic damage to these symptoms, and they can arise by suggestion, change or disappear by suggestion.

I guess it's a very thin book. I think. Mass hysteria is only possible in rural groups or when children are concentrated, and I can't think of much to be said in this book.

The reason why I was terrified was that the font I was familiar with, the same font as the small pencil writing of my book Diagnostics!

I also looked up at the sunlight outside the door. The sun is shining and we have a good day today. I said to myself, it must have been a coincidence
