Chapter 986: The Third Sub-question

Qi Changye shook hands with Jiang Yuan with a smile and said earnestly, "Team Jiang, we meet again."

"It's not necessarily a good thing, is it?" Jiang Yuan also shook hands with Qi Changye and then with the colleagues who came with him: "I've caused trouble for everyone."

"I wish for more trouble like yours." Qi Changye exchanged pleasantries to this point and whispered, "I heard you found a codebook?"

"You still have to check it." Jiang Yuan was both humble and distancing himself. He had received the legacy of LV5 Cryptography, but this kind of technology was ultimately quite sensitive, and those involved in espionage were even more sensitive. It was better not to let them worry.

Qi Changye naturally had to check it. Codebooks couldn't be delivered through the public network, and none of them had seen what it looked like before coming. At this moment, they found a room and took out the codebook to flip through.

The codebook Miao Liyuan brought back was a notebook in which some words and sentences were written with a fountain pen. They looked like excerpts from songs, but in reality, they all corresponded to some vocabulary, especially numbers and English letters.

The handwriting in the notebook looked a bit sloppy, and the notebook itself was an ordinary hard-shell notebook, belonging to the common goods of that year.

However, the few people Qi Changye brought looked at it very seriously. First, they flipped through it once, then started taking photos, and after a while, started making phone calls to communicate.

After tossing and turning for a while, Qi Changye invited Jiang Yuan, Tao Lu, and Director You into the room, looked at the three of them, and said, "You leaders are more familiar with confidentiality discipline than I am, so I won't say much. Let me state the conclusion first: it is indeed a codebook, but it's an excerpt."

"Can a codebook be excerpted?" Jiang Yuan knew that since Qi Changye said so now, he still had to use him. Anyway, it wasn't the first time they had cooperated on a case, so he asked without any scruples.

Qi Changye nodded and said, "The role of this suspect should be a semi-marginal, semi-core position similar to a courier, so he needs to master some codes. From our research and judgment, this codebook of his is mainly used for placing advertisements."

"Placing advertisements in newspapers and using code words to communicate with the other party?" Jiang Yuan asked.

Qi Changye nodded and said, "Yes. It should mainly be to communicate the time and place for picking up intelligence, as well as some issues about the amount of money..."

"That..." Director You suddenly interrupted the exchange between the two and said, "I won't participate in this case; you guys talk."

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

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

Jiang Yuan pulled back: "It's not appropriate for me to organize it. Besides, this case clearly involves things like espionage networks..."

"The case is directed and solved by your side; if you need any information, we will provide it to you," Qi Changye said immediately. "You have been following the case all along; now that you're handing it over to us, you wouldn't be at ease either."

This last sentence really hit Jiang Yuan's heart.

It's not that Qi Changye and the others' criminal investigation ability isn't strong, but for this kind of case from 20 years ago, even general strong criminal investigation ability is full of difficulties.

"Then let's look at the case first; what can I understand on my side?" Jiang Yuan simply sat down and took out his phone to send a message to Huang Qiangmin.

Qi Changye pretended not to see it and said, "We can check the information from that year based on the information in the codebook to see if it is an espionage network that has already been broken. If not, it depends on the specific situation. But honestly, if there is no record, then the clue in the code part is basically broken."

"You said the suspect's role is a courier; he often goes to the newspaper to place advertisements, right? Can you find the information of these advertising clients?" Jiang Yuan asked.

Qi Changye shook his head: "Basically impossible; it's been too long, but we can try to find it."

"Then it's still necessary to do it from the perspective of the homicide case." Jiang Yuan now understood a little why Qi Changye wouldn't let him go.

In the final analysis, it is more appropriate to do this case from the perspective of criminal investigation.

Thinking about it, espionage cases are all professionals, and current cases are very difficult to solve. How to solve an espionage case from 20 years ago? Just thinking about it makes people feel a headache.

"Call Liu Chu in to sort out the case together." Jiang Yuan dragged Liu Jinghui into the water without hesitation.

Qi Changye agreed.

Soon, Liu Jinghui and Huang Qiangmin entered the room together.

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

"It won't necessarily take longer." Jiang Yuan smiled.

"Why, do you have a new discovery?" Liu Jinghui was slightly surprised.

"No, but if the case can't be solved in a week or two, there shouldn't be any hope." Jiang Yuan smiled.

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

The information provided by Qi Changye and the others was little, but it was critical. Liu Jinghui finished reading it in a while and then started to think.

Jiang Yuan took the codebook back and flipped through it on his own.

"Now, the case has returned to the idea of plotting against a person. It can be considered a return to the right path." Liu Jinghui first sighed and then said: "If it's plotting against a person, what benefits can the other party get by killing Zhang Xiaoming?"

Liu Jinghui looked at Qi Changye.

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

"Yes. From your side. What's the use of killing Zhang Xiaoming?" Liu Jinghui paused slightly and explained: "The normal reasoning for plotting against a person has been discussed by the previous task force, including because of the layoffs, because of Zhang Xiaoming's personality, and also discussed love-related murder, or previous grudges, that is, the Zhang family factor, which has not been fully discussed."

"Killing him has no impact on the Zhang family. At least as far as I know, there should be no impact." Qi Changye's first sentence gave this answer, which 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 had to say it like this. However, from an efficient perspective, removing this false option was very effective.

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

Liu Jinghui continued: "Then, excluding these reasons, is there any reason to believe that Zhang Xiaoming's death is related to espionage?"

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

"I think it's related." Liu Jinghui answered very efficiently, seeing that Qi Changye was so efficient: "There are two reasons. First, the suspect Li Dianzhong has no other reason to kill Zhang Xiaoming; there is no other motive for murder. Second, looking at his actions, he should be trying to find something from Zhang Xiaoming. What could Zhang Xiaoming have that is worth an intelligence officer to search for?"

"Intelligence? Zhang Xiaoming can't come into contact with any intelligence." Qi Changye shook his head slightly.

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

"What do you mean?"

"Zhang Xiaoming might have discovered something, or got something in his hand, forcing them to have to take it back." Liu Jinghui spread his hands here and said: "I don't know much about espionage, but we have actually discussed this topic before. To kill Zhang Xiaoming directly, there is no need to be in his house, and there is no need to be at such a time and way. Therefore, there should be something in Zhang Xiaoming's house that the other party wants to take away."

Qi Changye didn't disagree with Liu Jinghui's words, just said: "You just said it was a case of plotting against a person."

"The person must be killed, and the things must be taken away. Now it seems that I think this is more reasonable." Liu Jinghui then talked about Zhang Xiaoming's injury site and added: "Li Dianzhong is a professional. If he didn't want to kill, he should have other means to deal with Zhang Xiaoming. Things like wearing a mask can also avoid direct conflict. For this kind of thing, ordinary thieves can't think of it, but professionals always have some means to deal with it."

"You say so, it makes sense... Then, what do they want?" Qi Changye paused and muttered to himself again: "Did they get it?" ===== CHAPTER 987 =====
