As the high school entrance examination approaches, Xun Dan's classes are becoming more and more busy. Pen & Fun & Pavilion www.biquge.info

Fortunately, the family's current economic situation is good, and he has already been equipped with a high-end computer.

With a computer, Xun Dan can easily know all the exam questions, and hacking into the printer of the teaching department is just a piece of cake for him now.

"Xiao Dan, the chief is here." Mother said at the door.

"Auntie, just call me my little grandson." The person who came was Sun Yi.

"Little Sun, come into the house and talk." Xun Dan didn't lift his buttocks, and teased.

"How can this kid talk to the chief?" Mother blamed.

Sun Yi just smiled and came directly to Xun Dan's room.

After closing the door, the smiles of both of them faded and changed to a serious expression.

"The person you said, I've been following it recently, if nothing is wrong, there should be a problem." Sun Yi was the first to speak.

"Got the evidence?"

"No, but there is a problem with his movements, he closely watched the situation of the bus with the quarantined people after leaving, and also bought all the newspapers in the last few days, and heard from the staff at the newsstand near his house that he had never bought them before."

"My suspicions were correct, but the lack of actual evidence was a headache for me. I checked the emails he received recently, and many of them were from abroad, but at present, our news network is still relatively closed, and I can't find the real address of overseas mail. ”

"You mean, you suspect he got the potion from overseas?"

"Yes, because from our internal case, our X city is only one of the crime points, so it is unlikely that it is the place of production, but if we want to find the final mastermind from this clue, it is still possible."

Xun Dan calmly analyzed.

Listening to Xun Dan's analysis, Sun Yi couldn't help but secretly admire, he didn't expect that Xun Dan would be able to get so many inferences from this small amount of information, and in the application on the Internet, he couldn't help but feel ashamed.

"What do you think now?"

"I don't think Wang Jianbao will not practice with his superiors, or use communication equipment, or connect with informants, in short, he will not always do it step by step."

"You mean we keep a close eye on him?"

"Yes, I can monitor the communication equipment of the Internet and telephone at any time, but it depends on you whether the actual handover with the informant is up to you."

"Well, it's almost zero difficulty for me to track him."

……

As Xun Dan expected, a few days later, Sun Yi really intercepted some information.

This is a list of doctors, all of whom are some medical workers in X City, and coincidentally, Xun Dan actually found Wang Huan's name.

Thinking of the man who was abandoned by the society because of his appearance, Xun Dan couldn't help but feel a little embarrassed.

After all, in terms of education and medical skills, Wang Huan is not weak, but now that he has fallen into this field, it really makes people feel that the world is cold.

"Xun Dan, what do you say this list is for?"

"I don't know, what's more interesting is that these people are no longer under our national network surveillance."

"What did you say?" Sun Yi said incredulously.

"Three possibilities, one, they are hidden. Second, they were smuggled abroad. Three, they have been killed. At this time, Xun Dan had no expression and said coldly.

These days of work have made Sun Yi feel Xun Dan's ability to work, and these judgment directions are beyond his reach.

Now in the work distribution of the two, Xun Dan has faintly taken the lead, while Sun Yi is more about collecting clues and giving tasks, but there is no doubt about one thing, the cooperation between the two is very tacit.

"Although there are these three speculations, the common denominator of these people is related to medicine, what may be their purpose?"

"Say it's to weaken the level of medicine in our country? It seems unlikely that these people are basically unwilling doctors, and if they are killed, it is not very likely. ”

"Are you saying they might be hiding, or they've been smuggled abroad?"

"Well, I'm more inclined to the first two."

"As long as it's in our country, we can find them out, but if we want to flee abroad, we'll have some trouble."

"Well, we're going to find out as soon as possible."

"I heard that he has been correspondingly with foreign letters, but from the letters, I have not found any clues."

"You mean foreign letters?" Xun Dan stood up suddenly, and if the speculation was correct, these letters could be extremely important clues.

"Yes, but we can't find the sender."

"******, what an old fox." Do you have any information about the letter?

"Yes, I took some pictures, and I'll wash them out for you tomorrow."

There are 10,000 ways to obtain the contents of a letter without the recipient's knowledge, but it is not easy to read the information from these letters with a specific code of other people.

The content of these letters is some professional questions in chemistry, and Xun Dan has no interest in these professional knowledge, but he dares to guarantee that these letters convey professional knowledge.

What's more special is that the outside of these letters are envelopes with grids, and the covers of ordinary letters are strip-shaped or blank, which makes Xun Dan have a trace of suspicion.

"You mean that in terms of content, our relevant departments have analyzed it?"

"Yes, these contents have been analyzed by our professional decryption department, and they should not be special passwords."

"It's strange, I'm getting more and more interested in this letter."

After reading the content of the letters several times, Xun Dan didn't feel half a clue, but Wang Jianbao was familiar with him, and he was definitely not the kind of person who studied hard, so there must be information they wanted to get in these letters.

Xun Dan opened this more chic envelope again.

The writing in the lattice is not neat, and it looks a little strange.

"If you look at this degree of distortion, it's a bit like down and down, up, up and up, down and up and down. There is a certain interval between these ones, left and right, up and down, do you know the password? ”

Xun Dan said.

"Of course, Morse Code?" Sun Yi replied.

Xun Dan ignored him, and turned on his computer instead.

For the compilation and interpretation of the password, Xun Dan's first thought was not to let this muscular man interpret it, but to turn on the computer to find it, and this result was more real.

"Down, down, up, up, up, down, up, up."

“stop！ Stop it! "I understand how they get their message across.
