Director Dai said: "The line should be followed from this window. Then, that person should be around here."

Zhou Yun nodded: "The bureau is wise!"

After saying that, Zhou Yun was stunned.

Tan Weixian and Director Dai saw Zhou Yun’s situation.

Tan Weixian: "What did you find?"

Zhou Yun said: "I just thought that the external wiring is not only traced inside the house, but also traced outside the house. However, we just couldn't find any trace outside the house, so it was strange. Now, I don't doubt it."

Director Dai asked: "You make it clear."

Zhou Yun pointed to a seal and said, "What is that?"

Tan Wei looked at it first and then said: "From the traces, it should be a bamboo pole."

"Not bad! It should be Arrow Bamboo." said Director Dai.

Zhou Yun said: "Arrow bamboo is the longest bamboo among all bamboos. Most people like to use it as a cool clothes rod. Judging from the length of this bamboo, it should be five meters long. Its length just rests on the wall."

Director Dai didn't understand: "Tell me more specifically."

"Staff, if someone opens the hollow of the bamboo pole and passes the external phone out of the bamboo pole, then we can't find any traces outside."

Everyone understands Zhou Yun’s statement.

Tan Wei ran out quickly, went outside the wall and looked, stretched out his thumb, and stood up to Zhou Yun in the window. That means that Zhou Yun’s guess was correct.

Zhou Yun came to the wall and saw a trace. It was the trace of the bamboo pole pressing against the wall.

Zhou Yun looked around again and found that outside the wall was blocked by three families.

The two families are residents, and their houses account for more than 20%. The remaining 80% were occupied by a unit of buildings.

Zhou Yun said: "Let's check those two companies first. If there is no problem with those two companies, the external line should be going to the building of that unit."

Immediately, the Military Control Commission people started working in that empty house.

Director Dai sat on the clean sofa, drinking tea and waiting for news.

Soon, Tan Weixian came in to report. "The two families, one of whom made steamed buns on the street, worked for ten years. The other family worked as workers in a food factory. Both of them were in the same factory, entering and leaving the same."

Director Dai asked: "Is there any situation in their home?"

"There are no traces of pulling the wire. Both rooms are dirty. If there are pulling the wire, we can find it."

Zhou Yun said: "It shouldn't be those two families. First, the one who bought steamed buns will not be sold until eleven o'clock as soon as possible before they can sell them home. They both went out and there was no one at home. They couldn't get the call from the colonel at all. And the two workers even said that they went to work in the morning and went home in the evening. How do they answer the call from the colonel?"

Director Dai said: "I think so too, the rest is that unit! What unit is that?"

Tan Weixian said: "The house of Changsha Institute of Disease Prevention and Control."

As soon as Tan Wei finished speaking, Zhou Yun stood up immediately.

Director Dai felt it and looked at Zhou Yun.

Zhou Yun said: "If the people who are most suitable for bacteria are not from the Disease Control and Prevention Institute, they can go to all places as soon as they get their ID. No one doubts him, let alone stop him."

Zhou Yun's words made Director Dai jump up: "Go to the epidemic prevention center right away."

Ten minutes later, the army surrounded the epidemic prevention center. A group of soldiers came, covering the surrounding area of ​​the epidemic prevention center.

Director Dai took over the epidemic prevention center with his military commanders.

A small conference room in the epidemic prevention center became Director Dai's temporary office.

Tan Weixianhui reported: "We investigated the residents around us. They said that there was no bamboo pole in the empty house. But after the family moved out, a bamboo pole appeared. Everyone thought it was made by the two families, so they didn't care. Until a day ago, the bamboo pole disappeared."

Zhou Yun has already gone back, it’s almost dark, and he is going back to the rented place.

Director Dai said: "When it's evening, someone will ask the two families if they know the situation of the bamboo pole. At the same time, I will investigate how many houses and offices are there next to the wall."

Zhou Yun returned to the rented house, had supper with everyone, and at seven o'clock, he locked the door and went to rest.

In this era, when it gets dark, there is nothing to do. Therefore, the number of games in bed has increased and the number of people has increased rapidly.

The members of the Secret Service also went to bed and rested.

They didn't know that Zhou Yun came out quietly and came to the epidemic prevention center.

Zhou Yun also visited the two families, and after that, he ruled out the people from the two families.

After arriving at the epidemic prevention center, Zhou Yun went directly to the office building.

If anyone can connect external cables, they can answer them. However, if a telephone line suddenly appears outside the wall, it will definitely be suspicious. Therefore, if this line is not noticed, it will not go very far.

Zhou Yun's goal was to the office close to the building with a walled wall with bamboo poles. The building only has three floors. The third floor was impossible. Because it was too conspicuous to cross the wall and the building's third floor.

The possibility of the second floor is not high, and it also needs to be crossed. There are five or six meters between the wall and the building, and it is impossible to cross the second floor without crossing it.

Only one layer is possible because Zhou Yun found a line on the first layer.

There is a lot of dust on this line, and it is an abandoned line. It should be the previous phone line, but later the line was changed, so no one uses this line.

Zhou Yun came to the middle of the waste line and saw a cutting hole. He immediately understood.

The telephone line in the empty room was sent to the top fifty centimeters of the waste line through a bamboo pole. Someone connected the wire sent by the bamboo pole to the waste phone line. So, the waste phone line was used.

After confirming these, Zhou Yun looked at the waste line from both ends. There was a waste wall on the left of the waste line, and when he got there, he did not extend forward.

There are no new traces on that waste wall, and it is not a wiring head here.

Looking back, Zhou Yun looked to the right. This check made him find a hole in the wall. There was a hole in the wall. The hole was very small and no one would pay attention to it. However, a telephone line could be extended.

There should be a telephone line behind the wall that stretched out and connected to the scrap line. So the phone number entered from the empty house was connected to a certain place on the first floor of the building.

When Zhou Yun arrived here, he couldn't check it anymore. He was an outsider and was not sure about the situation inside the epidemic prevention institute.

So, Zhou Yun went to the small conference room.

Following the breath, Zhou Yun came to the small conference room.

Director Dai and Tan Weixian were discussing the case, but suddenly the door opened quietly. While they were stunned, Zhou Yun walked in.

"Minister, I have discovered a new situation and report it to you!"
Chapter completed!
