I suddenly remembered that every time I met Professor Wang, I asked him where he had gone. Eight or nine times out of ten, all of them answered the library I went to. I didn't care about it at the time. Indeed, it is normal for a retired old professor, or an old professor in the history department, to go to the library to consult materials frequently. But, in my subconscious, I always felt that something was wrong. Where is it?

At this moment, my mobile phone rang, and when I saw it, it was the phone that Sun Xiaoping had opened. I was embarrassed to find that the silence in the conference room was broken by the ringing of the phone, and everyone was looking at me. I only had to explain to Zhang in embarrassment that I wanted to go out and answer the phone. Zhang Chu smiled and motioned for me to be casual. I hurried out.

In the corner of the hallway, I answered Sun Xiaoping's call.

"Hey, Brother Fei. I'm eating, what are you doing? Do you miss me? As soon as the phone was connected, Sun Xiaoping's voice came. Strange to say, she is a gentle and dignified person, but her voice is very playful when she speaks. The combination of "movement" and "stillness" is really perfect and balanced.

I quickly replied to her, "Oh, I'm working on it." I'm so busy that I don't have time to eat! "Because I was still thinking about what was abnormal in Professor Wang's words, I didn't want to talk to her more, so I didn't have a word to deal with her, and I was perfunctory.

"Humph! What's going on in your mind? You just decided on a relationship yesterday, and today you're so cold to me? On the phone, Sun Xiaoping was obviously displeased. Hey, women are really strange creatures. When I was just an ordinary friend of my childhood sweetheart before, she was still very polite when she talked to me. Now that the boyfriend and girlfriend relationship has been confirmed, it's starting to be a little rude. I almost wonder if someone from the mysterious organization used a voice changer to pretend to be Sun Xiaoping to trick me.

However, Sun Xiaoping's tone immediately became gentle again: "Brother Xiaofei, I know you're busy." But you also have to pay attention to your body. I was injured yesterday, so I need to eat more to make up for it today. "Hearing that her voice was back to normal again, I immediately understood that it was understandable that a girl with a spring was coquettish to her lover. In order to appease her, I also took the initiative to ask her, "Hey, have lunch?" How can you call me when you are available? How was the meal in the police academy cafeteria today? It's been a long time since I've been back to eat! ”

However, my shush cold and warm greetings aroused Sun Xiaoping's anger: "Let's just say that you don't care!" I'm a senior now, and I'm going to get an internship! Now I am interning at the Nanjing Road Police Station! Didn't I tell you before, how did you forget! I'm your girlfriend, please treat me with a snack! Thanks to me in the morning, I was reluctant to go far away, and Chef Bao, who took a detour to People's Square, bought you the pastries you like to eat! I'm angry! With that, he hung up my phone.

I immediately replied in a hurry: "Not like that, listen to my explanation, my dear. On the other end of the phone, Sun Xiaoping had already hung up the phone.

All that's left is the sound of beeping.

Love is such a strange thing. A little girl who was originally dignified and quiet has suddenly become unreasonable and unreasonable. It's really horrible! I shook my head helplessly. Forget it, she's angry, and she definitely won't listen to persuasion now. On the contrary, the more she explained, the more she was angry. When I get off work in the evening, go and coax her. Buying a small toy or something will definitely make her happy. Hehe, coaxing girls, it's that simple. However, I am quite happy to think that she deliberately went out of her way to buy me pastries!

Suddenly, I seemed to think of something! Seek the near and far, and seek the near and far。。。。。 That's right, there's a problem! I understand! I suddenly opened my mouth!

I rushed to the conference room and suddenly shouted excitedly, "I know!" I know! I've got a clue! ”

Everyone hurriedly gathered around me, looked at me, and looked at me with earnest eyes. Zhang Chu couldn't suppress the curiosity in his heart, and hurriedly said to me: "Xiaofei! I know you're right! Hurry up and talk about it! What a clue! ”

I casually picked up a copy of Professor Wang's letter on the table and said, "Every time I go to Professor Wang's house, Professor Wang continues to come back from the library. But, too coincidentally, right? A library every time? And.... ”

I was thirsty, so I picked up the teacup on the table and took a sip. immediately aroused Liu Xiahua's unhappiness: "And what? Don't be appetizing, hurry up! ”

I was embarrassed and said, "I'm not so excited that I'm thirsty!" Then, I continued: "And, please note that two blocks away from Professor Wang's house is the district library. However, every time, he went to the city library. The city library is not close to his house! By bus, you have to take nine stops away. If you take the subway, you will have to change the subway three times. For an elderly person, such a reluctant look must be abnormal! Ladies and gentlemen, I slowed down my tone and emphasized: "There must be a demon when things go wrong!" Leaving the district library only two streets away and not going, but going to the city library a little away, is this his hint to me? ”

Everyone immediately discussed it one after another, but immediately one of the team members asked: "This, it may also be because he is consulting very professional materials, after all, he is a professor in the history department, and the materials to be consulted must be very professional." Maybe the district library has a relatively small collection of materials, and it is definitely not as much as the city library's collection of materials, so in order to be able to find the professional information he wants, he deliberately went to the city library, which is also very reasonable. ”

At this moment, I am already confident. It's just because of Sun Xiaoping's words that I unintentionally woke me up. It seems that this girl is really still a lieutenant. No, it's still really Wangfu! Ha ha! Thinking of this, I blushed a little embarrassed myself.

However, with so many people present, I immediately recovered my demeanor and continued to explain to everyone: "First of all, every time Professor Wang chats with me, he always says that he has just returned home from the city library. That's what I say in every chat. If he didn't mean to remind him to say this, he just had to say, "The library is back." Why do you say that the city library is back? ”

When everyone was thinking, I picked up a copy of the letter and said to everyone, "Please read it carefully, what is the first sentence of the riddle in it?" ”

Zhang Chu picked up the copy, looked at it, he seemed to have found something, and asked me, "Do you say?" ”

I smiled and nodded: "That's right, the first sentence of the riddle is about being in the ocean of knowledge, and you are addicted to it." ”

I tapped my fingers lightly on the table a few times, and said calmly, "Everyone, the ocean of knowledge... This,Junior high school students know,What does it mean.。。。 That's right, it's books! And combined with the hints of Professor Wang in daily life, it shows that the place of the clue is in the city library! ”
