The emergency doctor was very busy, and after prescribing to Bai Song, he had to receive the next person, and Bai Song was embarrassed to waste the doctor's time excessively, so he went to pay the fee first, and then went into the treatment room to debride the wound first.

"Why are you so careless?" The nurse looked at Bai Song's hand: "You have a deep injury, it will hurt a little." ”

"Excuse me, just clean it up as much as you can. "Lessons from the past, Bai Song didn't dare to be vague about this at all. After speaking, he asked the nurse, "I heard that there was a tetanus death in our hospital a few days ago, is it really fake?"

"It's true, that person didn't treat it in time after he got sick", the nurse looked at these things relatively lightly: "He is not a good person, and this disease is particularly harmful to sucking." Originally, the disease tetanus, if it is sick and not treated, the case fatality rate is almost 100%, this is a kind of clostridium, very powerful, his body immunity, can survive until yesterday is good. ”

"The mortality rate is so high?" Bai Song was stunned.

"That's how it is if you don't treat your symptoms", the nurse said in a flat tone: "But you're right, come in time, just get a TAT injection." ”

"Okay, thank you nurse", Bai Song endured the pain: "You help me clean up a little, you're welcome." ”

"You said it earlier. The nurse breathed a sigh of relief.

"Hiss~" Bai Song gritted his teeth: "It's okay, I don't hurt." ”

...

Serum, it has to be real... (Note 1)

...

After cleaning up, he returned to the unit and took a look at the matter.

No matter what this equipment is, since it is placed near the Economic Investigation Corps, even if it has nothing to do with the incident of the Corps, it must be cleaned up.

Naturally, electronic equipment also pays attention to the "basic law", and the greater the capacity, the greater the power will naturally be required. A device that can support regional signal reception and transmission tasks usually has a power of tens of kilowatts, and the jammer encountered in Nanjiang Province last time has a power of several kilowatts.

According to the appearance of this device, the maximum battery is 12 volts, three or five ampere-hours of power, if it can run for more than a week at a time, the power is not much greater than that of a mobile phone.

A device of this power is absolutely unable to achieve effective signal jamming and signal eavesdropping.

The Economic Investigation Corps is an organ involved in secrets, and the anti-eavesdropping work is the basic work, so what is this thing for? Could it be that some criminals want to inform this thing that they are eavesdropping on the Economic Investigation Corps?

This is somewhat taken for granted.

Of course, there is also the possibility that this is a camera, which can shoot in real time...

But according to the current season, there are four days of smog in five days, which...

I really couldn't figure it out, so Bai Song decided to tell the Cao detachment about the situation the next day.

On Monday, after the meeting, Bai Song went to the office of the Cao detachment with a copy of "Organic Chemistry".

"Cao detachment, this is a book for Cao Yu. Bai Song said: "You can tell him that I can't give him this book, if he likes it, he can find a place to make a copy." ”

"Okay, I'll tell him. The Cao detachment was in a good mood: "How is the case going recently?"

After speaking, the Cao detachment sat down on the chair and motioned for Bai Song to sit as well.

"I didn't take many transcripts last Thursday and Friday, and I can't see anything yet. Bai Song thought for a while: "I judge that it will take two more weeks to be busy." When the time comes, I can report back to you on the results of the phase. ”

"Okay, no hurry. The Cao detachment nodded: "I didn't tell other leaders about you, your heart is good, I also support it, I have read the few transcripts you took, and I still have a foundation, and strive to finish it as soon as possible, don't talk to the rest of the task force about this matter." ”

Bai Song nodded gratefully, he still had a little headache about the things that might offend people when he retrieved the transcript.

There is no need to say anything else, Bai Song said directly: "Detachment Cao, I have something else to report to you, it is about my use of drones." ”

"Well, you say. ”

Bai Song didn't dare to say too much, and directly said what he had done in the past few days and what he had discovered yesterday, "I think it is still necessary to take it down and study what it is." ”

"Do you suspect that this is a bugging or video recording device?" When it comes to the security of the headquarters, the Cao detachment attaches great importance to it and sits very straight.

"Not really, but you have to know what it is, right?" Bai Song said, "Yesterday I went to the hospital with a hand injury, and I heard that someone died of tetanus because of a broken hand from climbing the chimney. I think it's the same people I just said installed it, and I'm worried about something else. ”

Bai Song carefully talked about the possible connection between what happened to the hospital yesterday and this incident.

"yes, I see. The Cao detachment said a few words to Bai Song, signaling that Bai Song could go to work first, and then call Bai Song if he had something.

Bai Song had just gone out, and the Cao detachment then instructed: "Don't go to the interrogation for the time being today, and get this matter out first." ”

"Understood. ”

...

Bai Song is waiting, it's afternoon. After lunch, the Cao detachment called Bai Song again and went to the door together.

"At noon, the drone with a robotic arm seconded from the technical detective went over to take a look, and it was indeed what you said, but it was fixed very well, and there was a card slot, and the installation time of the card slot should not be short, and it could not be removed with the mechanical arm. Cao Detachment said: "Considering that it is more dangerous to climb up directly, I borrowed a 75-meter-high rescue vehicle from the fire department. ”

...

We're not playing a game...

...

Bai Song and the Cao detachment went out together, got into the car, and soon after leaving the compound, they saw a large fire truck at the gate of the courtyard of the factory.

Bai Song may not know about some things, but the Cao detachment attaches great importance to it. The Economic Investigation Corps has zero tolerance for leaking secrets, and even if there is no harm to this equipment, it is impossible to let it exist, and even if it is taken down, it will "startle the snake." It is absolutely intolerable.

The doors of the abandoned factory had been completely opened, and there were a few people standing at the door, not like policemen, not like firefighters.

"What is this?" Bai Song was a little puzzled.

"This land is owned by a company. The Cao detachment looked at the chimney, "Let's go in the team and talk to the company." ”

Forehead... Bai Song was a little embarrassed, the Cao detachment must have known about him coming in over the wall......

With professional equipment, this matter became very simple, and with the elevation of the fire truck, soon, this small piece of equipment was removed.

Note 1: Tetanus vaccine is based on toxoid immunization, which usually requires three injections.

However, if there is a possibility of Clostridium tetani infection, tetanus antivenom (TAT) is injected, and the dose is doubled if the injection time and invasion time are more than 12 hours.
