Hua Zhang whispered, and then said: "There has been no change in the past hour. The wards in these three windows look suspicious to me. Counting from left to right, they are rooms three, five, and six."

Hearing this, Fan Keqin looked at his watch and said: "It's just seven o'clock now. Wait until eight o'clock. If there is no change, we will write it down first. The schematic diagram drawn by the heartthrob shows that there are wards on both sides.

.We will go to the other side and observe it when the time comes. Maybe the ward where Dubin is located is on the other side."

Some tasks are very boring and require hard work. They cannot be accomplished overnight. For example, waiting for letters, surveillance, investigating a person's life trajectory, etc. These must be accumulated bit by bit over time.

This was what Fan Keqin and Hua Zhang were doing at this time. After another hour or so, the lights in the ward that were originally dark came on, and there was a nurse, a doctor in a white coat, and two people in casual clothes.

, pushed a hospital bed and walked in. Then the nurse started giving intravenous infusion to the person lying on the hospital bed. In this way, this room can be completely eliminated. Then there are only two rooms with the curtains always drawn.

The two waited for a while. Fan Keqin looked at the watch and felt that it was almost done. He said, "No more waiting. In more than an hour, it will be time to turn off the lights in the hospital. Let's go to the other side to observe."

"Okay." Hua Zhang replied, put away the telescope, and left the edge of the roof with Fan Keqin.

Fan Keqin came to the patio, opened a small gap with a little force, and then listened. As a result, the sound of people walking came from the corridor this time. Fan Keqin had to signal to Hua Zhang, and the two of them waited until the sound came from the corridor below.

After there was a sound of opening and closing the door, I checked the movement again and then completely opened the ceiling cover.

Fan Keqin held Hua Zhang with one hand and tried his best to lean down. When Hua Zhang's feet were the shortest from the ground, he let go of his hand. As soon as Hua Zhang landed, he immediately bent his knees to relieve his strength and controlled the sound of landing.

To the smallest extent, he stepped aside to make room for Fan Keqin.

Fan Keqin was even simpler. He jumped down directly, held on to the iron railings on the wall, and re-covered the patio with one hand. Then he jumped down. The same procedure, tapping the toes, retracting the feet and bending over.

, bend your knees and control the volume.

Following the two people, they began to go downstairs as if nothing was wrong. After wandering out of the residential area, they deliberately took a detour. Then they arrived at the back of the hospital.

The back street of the hospital is not as good as the main road in front. It is just a two-way lane. The sidewalks on both sides are relatively narrow and there are fewer pedestrians. However, two people cannot just stand across from this back street and look behind the main building of the hospital.

Case.

So Hua Zhang put Fan Keqin's arm on his arm, and the two of them walked forward normally, observing as they walked. But at this time, they were not observing the hospital, but the residential building on the other side of the hospital.

Fan Keqin quickly locked several windows that might be unoccupied because they were completely dark. Of course, he did not rule out the possibility of people going to bed early at this point.

After walking for a while, the two people turned around and entered the residential area directly. After calculating their position, they entered the corridor where a window they had observed when they came over was located.

Spies are like this. The sense of space must be strong. If you position a window on the other side of the building and look at the back of the building, you can still estimate which corridor, which floor and which side the previously positioned window belongs to.

of the room.

The two people came to a door on the right side of the second floor. They looked at each other and Fan Keqin nodded. Hua Zhang immediately raised his hand and knocked on the door with a moderate voice. Then he stopped and put his ear to the door, quietly.

Listening to what's going on inside.

After a while, Hua Zhang knocked on the door again with greater strength, then leaned against the door and listened for a while. He shook his head towards Fan Keqin.

Fan Keqin understood that there was no movement inside. At this time, if the people inside had gone to bed early, they would have a higher chance of being in a light sleep state. Therefore, Hua Zhang had just knocked on the door twice, so it should be possible to let people inside

The person woke up.

Of course, everything has exceptions. It is possible that the people inside have been working for a day and fell asleep as soon as they touched the pillow. Therefore, we can only say that it is more likely that there is no one inside. But it cannot be said that there must be no one.

But now it's worth a try. Fan Keqin took out two iron bars, inserted them gently into the keyhole, pressed the circlip, and gently turned his wrist with the upper hook. The door lock was opened immediately.

Fan Keqin cautiously opened the door to a gap that allowed people to come in and out. Then he stopped. Hua Zhang first turned slightly sideways and walked in very lightly.

Fan Keqin did the same, raised his legs and landed lightly, entering the house. He turned back and gently closed the door again. He carefully checked the room. It was good, there was indeed no one.

So Fan Keqin whispered: "It's completely dark now, it's not like we had to wait for a while just now. Now we can observe for ten minutes, which is basically enough."

"Okay." Hua Zhang agreed, took out the telescope again, came to the window, and started to look at the back of the hospital.

This time it was clearer. After all, the back street of the hospital is very narrow, and the room the two of them are currently in is on the second floor, so there is no gap. They don't turn on the lights, so they don't worry about being able to see themselves from the outside. And the hospital's

room, but with the lights on, they can see more clearly.

Hua Zhang quickly looked through every room. Most of the wards on this side were occupied. One of the wards had dark lights. Another ward had its curtains drawn. In addition, the two wards on the front side had their curtains drawn.

Yes, there are four suspicious wards in total.

But now Hua Zhang found a more suspicious target at the back and said: "Brother, look at the back of the hospital. There are several wards here. They are different from the ones we saw in front. They are single rooms. This is

High-end wards. If Du Bin is in there, I think, given his status, he must be living in these high-end wards."

Having said this, Hua Zhang handed the telescope in his hand to Fan Keqin, and then said: "In addition, the wards with black lights... are less likely to be occupied. I think we can ignore the wards without lights for the time being. And in front of the hospital

The wards are, as I just said, basically all ordinary wards. The most suspicious thing is the ward behind this one with the curtains drawn. Look, the right side of this ward is darkly lit.
