Police Detective

"What's wrong with this floor?" Liu Shuyuan realized that he and Bai Song were not on the same line of thinking at all. When Bai Song came out to handle the case, his level of digging into some details was several levels higher than his. He could only ask humbly: "Don't hide it if you have something to say. I didn't find it anyway."

"Let's go from there to here. There is one strong current well and two weak current wells. This hospital is not too big, so why are there two weak current wells?" Bai Song asked in the corridor with some confusion.

"."

"Why don't you speak? There are no surveillance cameras in this corridor. You and I can talk." Bai Song felt that he couldn't figure it out.

"Um," Liu Shuyuan said: "What is a strong current well? What is a weak current well? Are they classified according to the 36-volt safety voltage?"

"No." While chatting, the two of them quickly reached the floor of the laboratory. It was no different from the other side. Bai Song glanced at it and continued walking up. "The strong current well is mainly the power supply line. Generally, it is It is high-voltage electricity of 220 volts, 380 volts and above, which is mainly used to power the building. The weak current well is used for optical fiber and telephone cables. The voltage of the telephone line is 110 volts, but it is also considered weak electricity."

"The strange knowledge has increased." Liu Shuyuan felt a little headache after hearing what Bai Song said on this occasion: "So it is because the hospital building requires a lot of cables that the two weak current wells you mentioned were installed?"

"But the weak current well is very large, and there is no need to run from the first floor to the thirteenth floor. Generally speaking, a pipe with a diameter of more than ten centimeters is enough to accommodate all weak current lines." Bai Song said: "This hospital is not a high-tech hospital. , do you need so many lines?”

"It's hard to say." When Liu Shuyuan heard this, he seemed to understand something: "Maybe when the hospital was first built, it was promoted as 'high technology'? Didn't you see that there is an entire floor idle as Tianhua Medical Department?" A university collaborative laboratory? I guess this is all a gimmick, and sometimes the gimmick is more important than the actual thing.”

"Well, that makes sense." Bai Song was convinced again. He always followed the good advice.

When they reached the thirteenth floor, they called the elevator. This time, the elevator that came up was not the previous one. The elevator attendant inside was a man. He didn't even ask about the floor. He just pressed the button for the first floor and reached the bottom of the building.

There were still no special vehicles such as ambulances at the door. Bai Song breathed a sigh of relief. After all, he had just seen a doctor giving first aid to a patient. He was really worried that he had occupied a special parking space.

Looking around, there was only one truck transporting medicine that was considered a hospital vehicle. There were no other vehicles with special signs. It was really deserted.

There was nothing to miss, Bai Song and Liu Shuyuan got into the work car directly and drove away from the hospital.

Halfway through the car on the road, Bai Song suddenly asked: "What time is it?"

"5:40", Liu Shuyuan was very happy and didn't have to work overtime.

"When did we go to the hospital?" Bai Song was a little confused: "Why didn't you ask us for money when you came out?"

"Hey, it's true when you say it." Liu Shuyuan just reacted: "Is it possible that we have less than an hour?"

"How is that possible? We spent a long time in the activity room and library alone. I remember that we entered the hospital around four o'clock. We came out of the unit at two o'clock, and we only stayed in the community hospital and health management center. A little over an hour and a half.”

"After one hour, the fee is 1 yuan per hour. I guess people won't bother to collect a dollar." Liu Shuyuan, who comes from a well-off family, never thinks much about a dollar.

"Maybe." Bai Song drove straight to the Economic Investigation Corps without any distractions.

When he returned to the unit, it was already time to get off work. Bai Song went to the Cao detachment immediately and gave a general summary of the clues he got from the health management center and hospital in the afternoon.

As for the problems in the hospital, most of them were just Bai Song's conjectures, so when he told the Cao detachment, Bai Song just said that he had gone around and found no useful clues.

"Is it a healthy hospital?" After hearing what Bai Song had learned in the afternoon, detachment Cao frowned and remained silent for a long time. Bai Song looked a little nervous.

"Okay, I understand. Don't continue to investigate this matter. I will tell the Tianbei Branch about the matter later." After detachment Cao finished speaking, he continued to emphasize: "Tomorrow, you can continue to interrogate those who have not finished questioning. The suspect, Xiao Liu, needs to complete the case file, and I will arrange for someone else to accompany you tomorrow."

"But, over there at the hospital"

"It's nothing." Detachment Cao interrupted Bai Song: "I just made it very clear about the hospital. This matter is considered a confidential matter. From now on, you are not allowed to communicate with anyone about what happened this afternoon. Including Xiaoliu.”

"Understood." Bai Song had a lot of things to ask, but he still nodded.

"Well, also, there is a May Day holiday the day after tomorrow. You have been working very hard recently, so pay attention to rest." Detachment Cao said: "If you are going to travel somewhere or go home or something, please hand over your leave slip as soon as possible and I will approve it for you. "

"Thank you, Detachment Cao."

"Okay, go out and call Xiao Liu over."

"good."

Bai Song left the house with a heavy heart, found Liu Shuyuan, informed him, and walked to his house.

Liu Shuyuan was still a little confused and wanted to ask Bai Song what was going on. Bai Song shook his head and didn't say much, letting Liu Shuyuan go directly.

When Detachment Cao just said these words, although they were not very harsh, Bai Song could see that Detachment Cao's emotions had already calmed down. If the Economic Investigation Corps does not have jurisdiction over this case, that would not be the case.

Detachment Cao is the leader of the detachment, and Liu Shuyuan is the policeman. According to common sense, detachment Cao should not directly ask Liu Shuyuan to say anything. Even if there is any personal relationship between them, Bai Song should not be allowed to call Liu Shuyuan.

In this case, there is only one possibility, and that is that detachment Cao personally asked Liu Shuyuan to keep the matter confidential.

Today is Friday, April 26th. Tomorrow is the 27th, go to work as usual. Because next Wednesday is May Day, the holiday time will be Sunday to Wednesday. Of course, I will go to work as usual next Saturday.

During the four-day May Day holiday, Bai Song had really planned to go out for a walk, but after being told by detachment Cao, he was no longer in the mood to play.

With thoughts racing in his mind, Bai Song opened the door and entered his dormitory.

Um?

Bai Song thought he had gone to the wrong house and there was someone in the house.

Without going out to check the room number, Bai Song determined that this was his own room from the things he laid on the floor, and then greeted the senior in the room.
