How could tetanus be so severe? The emergency doctor was very busy. After writing the prescription for Bai Song, he had to see the next patient. Bai Song was embarrassed to waste the doctor's time excessively, so he paid the fee first and then went into the treatment room to clean the wound.

"Why are you so careless?" The nurse looked at Bai Song's hand and said, "Your wound is very deep. It will hurt a little."

"Thank you, just clean it as thoroughly as possible." Bai Song was very clear about this after learning from the past. After that, he asked the nurse, "I heard that someone died of tetanus in our hospital a few days ago. Is it true?"

"It's true. The man didn't receive prompt treatment after he became ill." The nurse took these things lightly. "He's not a good person either. This disease is particularly harmful to drug addicts. Tetanus has a mortality rate of almost 100% if you get it and don't get treatment. It's a Clostridium, which is very powerful. With his immune system, he was lucky to have lasted until yesterday."

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

"That's what happens when you don't treat your symptoms," the nurse said calmly, "but you're right. You came in time. Just give it a shot of TAT."

"Okay, thank you, nurse." Bai Song endured the pain and said, "Please help me clean it up. Don't be shy."

"You should have told me earlier." The nurse breathed a sigh of relief.

"Hiss~" Bai Song gritted his teeth: "It's okay, I don't feel any pain."

…

The serum must be genuine... (Note 1)

…

After packing up and returning to the unit, Bai Song sorted out the matter.

He definitely couldn't handle the issue of this equipment by himself. No matter what this equipment was, since it was placed near the Economic Investigation Corps, it had to be cleared away even if it had nothing to do with the Corps' incident.

Electronic equipment naturally also pays attention to the "Basic Law". The greater the capacity, the greater the power required. A device that can support regional signal reception and transmission tasks usually has a power of tens of kilowatts. The jammer encountered in southern Xinjiang last time had a power of several kilowatts.

Judging from the appearance of this device, the maximum battery capacity is 12 volts and 35 ampere hours. If it can run for more than a week at a time, the power consumption will not be much greater than that of a mobile phone.

Devices of this power are absolutely incapable of effective signal interference or eavesdropping.

The Economic Investigation Corps is a confidential agency, and anti-eavesdropping work is basic work. What exactly is this thing for? Could it be that some criminals want to use this thing to eavesdrop on the Economic Investigation Corps?

This is somewhat taken for granted.

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

But according to the season now, there is smog four out of five days, this...

Unable to figure it out, Bai Song decided to tell Captain Cao about the situation the next day.

On Monday, after the meeting, Bai Song went to Cao's office with a book on "Organic Chemistry".

"Captain Cao, 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." Captain Cao was in a good mood: "How's the case going recently?"

After saying that, Captain Cao sat down on the chair and motioned Bai Song to sit down as well.

"We didn't take many notes last Thursday and Friday, so we can't tell anything now." Bai Song thought for a moment and said, "I think it will take another two weeks. Then I can report the interim results to you."

"Okay, don't worry." Captain Cao nodded. "I haven't told other leaders about your matter. You have good intentions and I support you. I've read the transcripts you took and they have a solid foundation. Let's finish it as soon as possible. Don't tell the other members of the task force about this matter."

Bai Song nodded gratefully. He still had a headache about the possibility of offending others by retrieving the transcript.

There was no need to say anything else, Bai Song said directly: "Captain Cao, I have something else to report to you, it's about my use of the drone."

"Well, go ahead."

Bai Song didn't dare to say too much, so he just told him what he had done in the past few days and what he found yesterday: "I think it's necessary to take it down and study what it is."

"Do you suspect this is an eavesdropping or recording device?" As it involves the safety of the headquarters, Captain Cao takes it very seriously and sits up straight.

"That's not the case, but we have to know what it is, right?" Bai Song said, "I went to the hospital yesterday with an injured hand, and I heard that someone died of tetanus after injuring his hand while climbing a chimney. I think it was installed by the people I just mentioned, and I'm worried about other problems."

Bai Song carefully explained what happened when he went to the hospital yesterday and the possible connection between this matter.

"Okay, I understand." Captain Cao said a few words to Bai Song, indicating that Bai Song could go and do his work first and he would call Bai Song when there was something else.

As Bai Song was about to leave, Captain Cao said, "Don't interrogate him today. Let's get this matter sorted out first."

"clear."

…

Bai Song waited until the afternoon. After lunch, Cao's team called Bai Song again and they went to the gate together.

"At noon, we borrowed a drone with a robotic arm from the technical investigation department to take a look. It was indeed there, but it was fixed very well. There was a slot that must have been installed for quite some time, so it couldn't be removed by the robotic arm." Captain Cao said, "Considering that it would be dangerous to climb up directly, I borrowed a 75-meter-high rescue vehicle from the fire department."

…

We are not playing a game...

…

Bai Song and Captain Cao went out together and got in the car. Shortly after leaving the compound, they saw a large fire truck at the gate of the factory yard.

Bai Song may not understand some things, but Cao's detachment takes them very seriously. The Economic Investigation Corps has zero tolerance for leaks. Even if the equipment does not pose any danger, it will not be allowed to exist. Even if removing it will "alert the enemy", it will never be tolerated.

The gate of the abandoned factory had been completely opened, and there were several people standing at the door. They didn't look like policemen or firefighters.

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

"This piece of land belongs to a company." Captain Cao looked at the chimney, "Since our team is coming here, we still have to talk to the company."

Uh... Bai Song felt a little embarrassed. Captain Cao must have known that he had climbed over the wall to get in...

With professional equipment, this matter became very simple. As the fire truck rose, the small equipment was quickly taken down.

Note 1: Tetanus vaccine is based on toxoid-based immunization and usually requires three injections.

If there is a possibility of infection with Clostridium tetani, tetanus antitoxin serum (TAT) needs to be injected. If the injection time and wound time exceed 12 hours, the dose should be doubled.
