Chapter 1003 The Third Question
Qi Changye shook hands with Jiang Yuan with a smile on his face and said seriously: "Captain Jiang, we meet again."

"It's not a good thing." Jiang Yuan also shook hands with Qi Changye, and then shook hands with Qi Changye's colleagues who came with him: "I'm sorry to trouble you all."

"I wish I could come more often for your trouble." Qi Changye said at this point in the greetings, and whispered, "I heard that you found a code book?"

"You guys have to check it out." Jiang Yuan was being modest, but also trying to distance himself from the matter. He was a descendant of Level 5 cryptography, but the technology in this area was still relatively sensitive, and espionage personnel were even more sensitive, so it was better not to worry them.

Qi Changye would naturally check it. The code book was not easy to send through the public network, and they had not seen it before they came, so they would find a room and take out the code book to look through it.

The code book that Miao Liyuan brought back was a notebook with some words written in pen in it. It looked like an excerpt from a song, but in fact, they all corresponded to some words, especially numbers and English letters.

The handwriting in the notebook looked a bit sloppy, and the notebook was just an ordinary hard-cover notebook, a common item at the time.

The few people brought by Qi Changye looked at it very seriously. They first flipped through it, then started taking pictures, and after a while, they started to communicate on the phone.

After a long struggle, Qi Changye finally invited Jiang Yuan, Tao Lu and Director You into the room. He looked at the three of them and said, "The leaders are more familiar with confidentiality than I am, so I won't say much. I will first state the conclusion. It is indeed a code book, but it is an excerpt."

"Can we still copy excerpts from the code book?" Jiang Yuan knew that since Qi Changye said so, he would still have to use his. Anyway, it was not the first time he cooperated with them in solving a case, so he asked without hesitation.

Qi Changye nodded and said, "The role of this suspect should be a semi-peripheral and semi-core position similar to a courier, so he needs to know some codes. From our analysis, his code book is mainly used for advertising."

"Put an advertisement in the newspaper and communicate with the other party using secret language?" Jiang Yuan asked.

Qi Changye nodded and said, "Yes. The main thing should be to communicate the time and place to obtain the intelligence, as well as some questions about the amount of money..."

"Um..." Director You suddenly interrupted the conversation between the two and said, "I will not participate in this case. You guys can talk about it."

After saying that, Director You nodded to Jiang Yuan, turned around and went out.

Qi Changye naturally did not stop him. He just smiled at Jiang Yuan and said, "Captain Jiang, you can't just walk away. We still hope that you can preside over this case."

Jiang Yuan hesitated for a moment and said, "It's not appropriate for me to organize it. Besides, this case obviously involves something like an espionage network..."

"You will be in charge of the investigation. If you need any information, we will provide it to you." Qi Changye said immediately, "You have been following the case all along. You may not feel at ease if you let us handle it now."

The last sentence really touched Jiang Yuan's heart.

It’s not that Qi Changye and his colleagues’ criminal investigation capabilities are not strong, but a case like this one that happened 20 years ago would be fraught with difficulties even with strong criminal investigation capabilities.

"Then let's take a look at the case first. What can I know?" Jiang Yuan simply sat down, took out his cell phone and sent a message to Huang Qiangmin.

Qi Changye pretended not to see it and said, "We can use the information in the code book to check the data from that year to see if it is a spy network that has been uncovered. If not, it depends on the specific situation, but honestly speaking, if there is no record, then the clues to the code are basically gone."

"You said the suspect is a courier. He often goes to newspapers to place advertisements, right? Can you find the information of these advertisers?" Jiang Yuan asked.

Qi Changye shook his head: "It's basically impossible. It's been too long, but we can try to look for it."

"Then we still have to do it from the perspective of a homicide." Jiang Yuan now understood why Qi Changye was holding on to him.

Ultimately, it is more appropriate to approach this case from a criminal investigation perspective.

Come to think of it, espionage cases are handled by professionals, and current cases are difficult to solve. How can we solve espionage cases from 20 years ago? It’s a headache just thinking about it.

"Let's call Director Liu in to help investigate the case." Jiang Yuan dragged Liu Jinghui into the case without hesitation.

Qi Changye agreed.

Soon, Liu Jinghui and Huang Qiangmin came in together.

Liu Jinghui smiled bitterly and said, "I was planning to go home in a week or two."

"It may not be longer." Jiang Yuan smiled.

"What? Do you have any new discoveries?" Liu Jinghui was slightly surprised.

"No, but if the case cannot be solved in a week or two, there will be no hope." Jiang Yuan smiled.

"You..." Liu Jinghui was helpless. If it were another young criminal policeman, he would have scolded him for talking nonsense, but since it was Jiang Yuan, then it would be fine.

The information provided by Qi Changye and others was very little, but very crucial. Liu Jinghui finished reading it in a short while and then began to think about it.

Jiang Yuan took the code book back and started flipping through it.

"Now, the case has returned to the idea of ​​murder. It can be regarded as returning to the right track." Liu Jinghui sighed first, and then said: "If it is murder, what benefits can the other party get by killing Zhang Xiaoming?"

Liu Jinghui looked at Qi Changye.

"Are you asking me?" Qi Changye pointed at his nose.

"Yes. From your perspective, what's the point of killing Zhang Xiaoming?" Liu Jinghui paused and explained, "The previous task force has discussed the normal ideas of murdering someone, including the layoffs and Zhang Xiaoming's personality. They also discussed emotional murders, or previous feuds, that is, the Zhang family, but they didn't discuss it fully."

"Killing him will have no impact on the Zhang family. At least as far as I know, it should have no impact." Qi Changye gave this answer in his first sentence. It was not easy. It was also because he trusted Jiang Yuan very much that Qi Changye gave this answer.

Qi Changye also knew that this answer would directly affect the investigation direction of the task force. If he didn't want to take responsibility, he wouldn't have said it. However, from an efficiency point of view, eliminating this false option is very effective.

Huang Qiangmin understood as soon as he heard it and whispered something in Jiang Yuan's ear.

Liu Jinghui continued, "Now if we exclude these reasons, do we have reason to believe that Zhang Xiaoming's death was related to spies?"

"What do you think?" Qi Changye asked back.

"I think it is related." Seeing Qi Changye's efficiency, Liu Jinghui also answered efficiently, saying, "There are two reasons. First, the murderer Li Dianzhong had no other reason to kill Zhang Xiaoming, and no other motive for murder. Second, judging from his actions, he should want to find something from Zhang Xiaoming. What could Zhang Xiaoming have that was worth a spy like him to look for?"

"Intelligence? Zhang Xiaoming doesn't have access to any intelligence." Qi Changye shook his head slightly.

"If it's not for intelligence..." Liu Jinghui just paused for a moment, without thinking too much, and said: "Could it be to protect himself?"

"What do you mean?"

"Zhang Xiaoming may have discovered something, or got something in his hand, forcing them to take it back." Liu Jinghui said here, spreading his hands and said, "I don't know much about spies, but we have actually discussed this topic before. If you want to kill Zhang Xiaoming directly, there is no need to kill him at his home, and there is no need to do it at this time and in this way. So, there must be something in Zhang Xiaoming's home that the other party wants to take away."

Qi Changye didn't disagree with Liu Jinghui's words, he just said: "You just said it was a murder case."

"The person must be killed and the things must be taken away. Now it seems to me that this is more reasonable." Liu Jinghui went on to talk about the injured parts of Zhang Xiaoming, and then said: "Li Dianzhong is a professional. If he doesn't want to kill, he should have other means to deal with Zhang Xiaoming. Including wearing a mask, which can also avoid direct conflict. Ordinary thieves can't think of this kind of thing, and professionals must have some means to deal with it."

"What you said makes sense... Then, what do they want?" Qi Changye paused and said to himself: "Did they get it?"
