Police Detective

　　 "What can be 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 excavation of some details was several levels higher than that of him, so he could only ask humbly: "You old man have something to say, don't hide it, I didn't find it anyway."

　　 "Let's come from over there, here, there are a strong electric well and two weak electric wells. This hospital is not too big, why do we need two weak electric wells?" Bai Song asked in a puzzled manner in the corridor.

　　"..."

　　 "Why don't you talk? There is no monitoring in this corridor, you can talk to me." Bai Song felt that he couldn't figure it out.

　　 "Um..." Liu Shuyuan said: "What is a strong electric well? What is a weak electric well? Is it classified according to the 36-volt safety voltage?"

　　......

"No." After chatting, the two of them quickly reached the floor of the laboratory without any difference from the other side. Bai Song glanced at it and continued to walk up. "The strong electric well is mainly the power supply line. It is high voltage power of 220 volts, 380 volts and above, which is mainly used for building power supply. Weak current wells use optical fiber and telephone cables. The voltage of the telephone line is 110 volts, but it is also a weak current." 78 Chinese first published https:// https://

　　 "Weird knowledge has increased..." Liu Shuyuan had a headache listening to Bai Song on this occasion: "So because the hospital building needs a lot of cables, two weak current wells you mentioned are installed?"

"But the weak current well is very large, and there is no need to penetrate the thirteenth floor from the first floor. Generally speaking, a pipe with a diameter of more than ten centimeters is enough to accommodate all the 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." Liu Shuyuan heard this and seemed to understand something: "Maybe the hospital was built with "high-tech" as a propaganda? You haven't seen a whole floor that is still idle as the Tianhua Medical Department. Is it a university cooperative laboratory? I guess these are all gimmicks, and sometimes, gimmicks are more important than actual things.” ァ78中文ヤ~⑧~1~ωωω.7~8z~w.còм

　　 "Well, that's reasonable." Bai Song was persuaded again, and he had always followed kindness.

　　 When they reached the 13th floor, the two called the elevator. This time it was not the previous elevator. The elevator inside was a man. He didn't ask the floor at all, so he helped them press the first floor and reached the bottom.

　　 There is still no special vehicles such as ambulances at the door. Bai Song breathed a sigh of relief. After all, he just saw a doctor doing first aid to patients. He was really worried that he would occupy a special parking space.

　　 Looking around, a truck that transports medicine is regarded as a hospital car. There is no other car with a special sign. It is really deserted.

　　 There was nothing to miss. Bai Song and Liu Shuyuan got into the unit's car directly and drove out of the hospital.

　　 The car was halfway on the road, and Bai Song suddenly asked, "What time is it?"

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

　　 "What time 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, when you say it, it's true." Liu Shuyuan also just reacted: "Could it be that our time is less than an hour?"

"How is it possible? I spent a long time in the activity room and library. I remember that we should have entered the hospital around four o'clock. We left the unit at two o'clock and stayed in the community hospital and health management center. It took a little over an hour and a half."

　　 "After more than an hour, the charge will be 1 yuan per hour. It is estimated that people are too lazy to charge a dollar." Liu Shuyuan, who is from a very good family, never thinks about a dollar.

　　 "Maybe." Bai Song drove the car without any distraction, and went straight to the Economic Investigation Corps.

　　 Back at the get off work unit, it was time to get off work, Bai Song went to Qin Detachment as soon as possible, and talked about the clues he got from the health management center and hospital in the afternoon.

　　 Most of the questions about the hospital were Bai Song's conjecture, so when talking to Cao Detachment, Bai Song just said to go around and found no useful clues.

　　 "Healthy hospital?" After Qin Detachment listened to Bai Song's harvest in the afternoon, his brows furrowed, and Bai Song was a little nervous when he didn't say a word for a long time.

"Okay, I see, don't continue to investigate this matter. I will tell the matter to the Tianbei branch later." After Qin Detachment finished speaking, he continued to emphasize: "Tomorrow you will continue to interrogate those who have not finished inquiring. Suspect, Xiaoliu has to make up a supplementary file. I will arrange for someone to accompany you tomorrow."

　　 "But, over there from the hospital..."

"Nothing." Qin Detachment interrupted Bai Song's words: "I just said very clearly about the hospital. This is a confidential matter. From now on, you can't communicate with anyone about this afternoon. Including Koyanagi."

　　 "Understood." Bai Song wanted to ask a lot, but nodded.

"Well, also, the day after tomorrow will be a May Day holiday. Recently you have been very hard. Pay attention to rest." Cao Detachment said: "If you are going to travel or go home or something, the leave slip will be handed in early and I will approve it for you. "

　　 "Thank you Cao Detachment."

　　 "Okay~www.novelmtl.com~You can go out and call Koyanagi here by the way."

"Great."

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

　　 Liu Shuyuan was still a little bit confused. He wanted to ask Bai Song what was going on. Bai Song shook his head, without saying much, let Liu Shuyuan go directly.

　　 When the Cao Detachment just said these words, although it was not very harsh, Bai Song could see that the Cao Detachment's mood had been very restrained. If it was just that the Economic Investigation Corps did not have jurisdiction in this case, that would not be the case.

　　 Cao Detachment is the leader of the Detachment, and Liu Shuyuan is the policeman. According to common sense, Cao Detachment should not directly talk to Liu Shuyuan. Even if they have direct personal relationships, they should not let Bai Song call Liu Shuyuan.

　　 In this way, there is only one possibility, and that is that Cao Detachment will personally ask Liu Shuyuan to keep secret about this matter.

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

　　 During the four-day May Day holiday, Bai Song had really planned to go out for a walk, but when Cao Detachment said so, he was no longer in the mood to play.

　　 Thoughts flew in his mind, Bai Song opened the door and entered his dormitory.

Ok?

　　 Bai Song thought he had gone to the wrong house, and there were people in the house.

　　 did not go out to check the room number, Bai Song confirmed from the things on his shop that this was his house, and then greeted the senior in the house.
