Chapter 1004 AF lacks fresh water

"He should have gotten it. Otherwise, they should have arrested Zhang Xiaoming and questioned him instead of just killing him."

Liu Jinghui used simple reasoning to solve a complex problem.

Qi Changye nodded unconsciously: "That makes sense. If we really can't find it, the worst that can be done is to light a fire and burn down the room."

At this time, Qi Changye felt the benefits of the King of Reasoning. It was very difficult to disprove a case that had been pending for 20 years with evidence, but an effective reasoning directly solved the problem.

There was no trace of pride on Liu Jinghui's face. This kind of reasoning was too easy for him. After talking about the case for a few more words, Liu Jinghui's expression became a little more serious and he said, "The key question now is, have you cracked the intelligence network? Have you made any relevant discoveries?"

Qi Changye hesitated for a moment and said, "I have actually sent people to investigate, but nothing has been found so far. Logically speaking... well, it should not have been solved. Otherwise, if it involves the Zhang family and Jianmenyuan case, there would always be some feedback."

"So, this spy network is still operating?"

"That... that may not be the case." Qi Changye paused, then continued: "We don't need to think too much of this spy network. There are very few spy networks that have been running for 20 years without being discovered. Of course, the ones we have heard of were all discovered. But under normal circumstances, if an intelligence team can survive for 20 years, it is most likely because it is in its dormant period and has not yet been activated."

"You mean, Zhang Xiaoming discovered a dormant spy group?"

"This possibility is actually very low, since it is in the incubation period... But who knows, maybe there is some coincidence." Qi Changye spread his hands: "Isn't it said that reality is more outrageous than fiction? This is even more true in the field of intelligence, because there are many unlucky bigwigs who have been caught."

Qi Changye usually doesn't talk so much, but today he was asked to provide information. Qi Changye paused for a moment and then said, "There is another possibility. What Zhang Xiaoming discovered might be a spy network that was in operation or had just begun to lurk. After the other party's intelligence officer discovered it, he dealt with the problem while switching the spy team from active to latent, or went back to latent, or simply withdrew it."

"If it is withdrawn, won't the case end here?" Huang Qiangmin couldn't help but say.

Qi Changye said helplessly: "There are indeed many unsolved cases. But on the bright side, most spy networks are mainly composed of local defectors, so there are very few cases of withdrawal. Most of them are re-entering the market."

"It's been 20 years, and you still haven't withdrawn it?"

"It's only possible. But it's not necessary. The defectors are valuable assets if they stay in the local area. If they are withdrawn, they can only be kept and become negative assets."

"So..." Liu Jinghui pondered.

Qi Changye continued, "Generally, in very advanced spy networks, there will only be one or two intelligence officers on the side, and more often than not, there will be none. These intelligence officers are mostly responsible for liaison work, and if they are not careful, they may have diplomatic identities... In this case, there is no possibility of high-value intelligence at present."

Sending intelligence officers to perform undercover missions in foreign countries is a very advanced spy network, just like sending police officers undercover in criminal organizations. Such huge risks must have corresponding benefits. Is an ordinary criminal organization worth the risk of a police officer? And can the police undercover get greater benefits?

Similarly, if we send out our well-trained intelligence officers, will they be able to gather more intelligence? Furthermore, if this intelligence officer is caught, will he leak more intelligence than he gains?

Therefore, even the intelligence network that Qi Changye came into contact with was mostly composed of local members who had been instigated to defect.

"In this case, we need to re-examine the work done by Zhang Xiaoming before his death. I remember someone seems to have done work in this area." Liu Jinghui said as he picked up the phone and asked someone to find the information.

After a while, Wang Chuanxing came in with something.

The previous task force had already determined Zhang Xiaoming's movements in the three days before his death based on testimonies from all parties and visits to the surrounding area.

Looking at the densely packed time in the notebook, it can be said that this set of trajectory charts is very solid.

It just doesn't work.

This is what criminal investigation is like. If you can’t solve the case, everything is in vain.

The bitterness of criminal investigation and the sweetness of working in the government correspond to each other.

Jiang Yuan took the trajectory map and slowly flipped through it.

Liu Jinghui and Qi Changye were still discussing the case and began to carry physical evidence over.

"Have you found the newspaper?" Jiang Yuan finished reading Zhang Xiaoming's movements and still had no idea. His solution was still to ask for more information.

Qi Changye stopped talking to Liu Jinghui, took a sip of water, and said, "They are looking through records in several newspapers. Now they are mainly trying to confirm the name of the person who posted the advertisement. There was no real-name system when posting advertisements back then. You could post them as long as you paid the money. There was no requirement for an ID card or anything like that. We don't know how many names the suspect used."

“Even if it is not a specified time, the advertisement should be placed on the specified page of the specified newspaper with a conspicuous sign, so that it can serve as a code.” Jiang Yuan casually reminded.

"Jiang Yuan is knowledgeable." Qi Changye sat up, looked at Jiang Yuan, and smiled, "We also searched in this way. We have found two newspapers now, but not all of them. Also, they are translating, but because the code book is incomplete, the content they translated is not comprehensive."

"Send what you found here first. I can help take a look." Jiang Yuan used his usual explanation, saying, "Since I worked on the case of that cryptographer last time, I've also been looking at some cryptography stuff."

Qi Changye looked at Jiang Yuan suspiciously, not surprisingly: "Have you studied cryptography?"

“It’s OK.”

"Well... okay, I'll have someone send the pictures over?" Qi Changye thought, no matter how good your cryptography skills are, can they be better than the cryptography experts in our company? However, this case obviously could not be solved simply by relying on cryptography, and Qi Changye would not hide the evidence.

After a while, Qi Changye brought a three-proof notebook and showed the pictures inside to Jiang Yuan, saying: "We have found that there are two newspapers that the suspect often publishes, "China Television News" and "Democracy and Legal System". The ads are in the middle of the newspapers, within 30 words, and the time is uncertain. The names of the people who advertised are all 'Liu, Guan, and Zhang'."

"The Three Kingdoms." Jiang Yuan said as he looked at the newspaper advertisement scanned from his rugged notebook.

There is only an advertisement in the center of the first page: There are two bulls, three years old, blue, bright fur, healthy, need to be sold due to production changes, if interested, please call BP number: 126***

Jiang Yuan pointed at the BP number and asked Qi Changye: "Is this BP number fake?"

"It should be fake. The numbers in each advertisement are different, and I haven't had time to check it carefully." Qi Changye had only taken over not long ago.

Jiang Yuan nodded, and continued to flip through the advertisements one by one, taking notes from time to time.

Qi Changye waited for a while, then gradually shifted his attention and continued talking with Liu Jinghui.

Soon, calls from all sides started coming in, and Qi Changye became even busier. He had to open a separate office and start working on-site.

This job was obviously not easy. Soon, Qi Changye began to feel overwhelmed and the sound of him shouting for help became louder and louder.

Jiang Yuan and Liu Jinghui were discussing in a low voice, and their voices began to get smaller and smaller.

Finally, when Qi Changye's voice began to rise, Jiang Yuan waved and called him over.

"I have some discoveries here." Jiang Yuan said.

"From where? The password?" Qi Changye was even more surprised. He hadn't seen Jiang Yuan go out, and the only new evidence was the password book.

"Yes." Jiang Yuan answered readily.

Qi Changye was puzzled and said, "You translated the code? The code book we confiscated was only part of it."

It's not that he doesn't believe it, he just thinks it's unreasonable. An incomplete code book would naturally make it difficult to fully translate the code. Moreover, if Jiang Yuan could handle these things, wouldn't his own experts be able to produce results earlier?

Jiang Yuan didn't need to explain so much, he just waved his hand and said, "It's true that the password extracted by the suspect is incomplete, but we should consider why he extracted the password."

"why?"

Jiang Yuan unfolded his notebook and said, "I think the suspect couldn't remember so many passwords. Li Dianzhong had a low level of education and probably had no interest in memorizing passwords, so he wrote down some of the passwords. From the excerpted passwords, we can see that he mostly wrote down some uncommon words and phrases, as well as some numbers and letters. It's probably for the convenience of searching."

Jiang Yuan said this and emphasized: "In other words, some of the codes that Li Dianzhong was already familiar with were not written down by him. In this regard, I sorted it out and found some high-frequency words that can be reasonably guessed."

"Midway Island?" Qi Changye quickly recalled this famous code story during World War II.

"That's right." Jiang Yuan drew a line in front of his face with his hand: "Three, represents the mimeograph factory."
