It's still the same room, similar to the one I had when I first went in more than an hour ago. It's just five more colleagues from the intelligence analysis team of the ten divisions. Oh, and by the way, my identity has changed. At this moment, my status has changed: I am now a member of the Ten Temporary Transfers. Therefore, I should be more concerned about this case. Because I am not only a key witness in this case, but now I am also a participant in the investigation of this case.

Everyone was sitting, but the atmosphere was very strange: no one spoke, everyone was looking at a copy of the letter Professor Wang had given me. That's right, everyone has a copy in their hand, and they are carefully figuring it out. However, no one has put forward their own opinions.

"So, who can tell us what they think first?" Zhang broke the silence and spoke first. He continued: "Everyone speaks freely, makes bold assumptions, and carefully verifies. After all, Professor Wang's letter to Xiaofei is a key breakthrough point. After all, that's the only clue. "And," Zhang's tone was also serious: "Attack Xiaofei and take the book away." explained the mysterious organization, and also knew that Professor Wang might have left a clue. Zhang Chu paused, thought for a while, and then said: "The mysterious organization, maybe because the clues are in the book, I didn't expect Professor Wang to design it so cleverly, the book is just a cover-up, the key is this letter." Now, the mysterious organization may still be working that letter. That's a good thing for us! ”

A member of the group immediately asked him: "Zhang, why do you say that?" Zhang Chu smiled: "They must be just desperately studying that book now, and they don't know that the real clues are in our hands at the moment." We can just take advantage of this time difference, study the mystery first, and then we can get the hidden treasure of Professor Wang before they do! "Oh! So that's it! There was a conversation in the room, and everyone seemed to agree with Zhang's idea.

"But ah, we're running out of time! In case the mysterious organization learns this clue through other means. This possibility is not ruled out. Then maybe you can get the treasure before us. In that case, we are very passive! Zhang's words made us break out in a cold sweat behind us. Zhang Chu is right, the treasures that belong to the country, if they are taken away by that mysterious organization, it will be a huge loss for the country!

Seeing that our spirits were lifted, Zhang Chu nodded with great satisfaction, and continued: "At present, the direction of the investigation is divided into two parts. The first part investigates what the mysterious organization really is. The second part is to investigate the letter. I'm sorry that you're still investigating the mysterious organization this morning, so I'm going to call you over to investigate the letter. There's no way, there's no time to wait. The mystery is directly related to the whereabouts of the treasure, so this is the most important thing. ”

After exchanging views with each other, one of the members said, "Zhang, we have studied until now. But no matter what method we use, the number arrangement, the code decipherment, it is all used, but it is useless. I really don't know where to start. After saying that, the atmosphere in the room suddenly fell again.

A team member suddenly put forward an idea: "That, Cheng Fei, in fact, the most critical person in the whole case is actually you." Now it seems that Professor Wang started with the layout. And you, are part of his layout! You are like, like ... He was embarrassed and didn't know how to continue.

I understood what he meant, and I didn't mind and said, "I understand what you mean." Professor Wang, in fact, treated me as a pawn in the whole game. After saying this, I felt so embarrassed myself, and I only smiled self-deprecatingly.

Zhang Chu walked over and patted me on the shoulder. He said to me, "Don't worry too much. I'm sure that's not what Professor Wang meant. From his letter, it can be seen that the only person he trusts is you. It can be seen that he entrusted the whole thing to you. Don't be pressured, think about it, and see if there are any clues. One of the team members immediately said to me, "Yes, think about it." What did Professor Wang say to you before his death, especially what he repeatedly mentioned to you? These words may be the hint he gave you. Maybe when he says it, even if he hints at you repeatedly, you won't care. However, with this letter, maybe it is a hint to you, and it is possible. So, Cheng Fei, think about it. Don't miss a single detail. Every detail counts! ”

Zhang Chu also continued to encourage me: "Yes! Now, this fierce medicine lacks a medicine lead. You are the medicine lead. So don't be in a hurry and think slowly. When Professor Wang communicates with you in daily life, think about every word he says. ”

With everyone's encouragement, I slowly closed my eyes and began to reminisce.

In my mind, I recalled the bits and pieces with Professor Wang. Since Professor Wang is an elderly lonely, I go to visit Professor Wang's house almost every week, sometimes with the cadres of the neighborhood committee, and sometimes by myself.

Professor Wang is still very hospitable, whether I go with the cadres of the neighborhood committee or I go alone, I am very enthusiastic every time. Serve tea and water, especially on hot days, and even prepare watermelon. At first, I was embarrassed and refused to eat his watermelon. But it only drew his bearded glare, and every time he said to me, "You are old enough to be my grandson." Grandpa gave his grandson watermelon, how could he not eat it? If you don't eat it, you will make the old man unhappy! Not filial! Come! Hurry up and eat! "Every time, I can't debate him, and in the end I can only obediently eat his watermelon.

When I think of this, I can't accept the reality that Professor Wang has left this world! How could such a good old man, such a kind old man, be poisoned by bad people! Thinking about this, my nose is a little sore. It strengthened my belief in solving the case. I tried harder to recall what Professor Wang had said to me in a way that hinted at me. However, the team member and Professor Wang analyzed just now, and the hint he gave me may have been pretending to be inadvertent, and I won't pay attention to it at once. But in conjunction with this letter, it may have taken my attention. So, what is the implication? At the very least, it must be words disguised as everyday language, but what is it?

Suddenly! A voice seems to come out of my head! That's right! I remember! There is a sentence that Professor Wang has often said to me!
