In its realization stage, Sun Jie is definitely better than Huadong when it comes to on-site investigations. After all, this is one of the duties of forensic medicine, and forensic medicine itself belongs to the on-site investigation department. It was just that Huadong took the initiative to invite Ying, and Sun Jie didn't say anything.

The four of them went up the mountain little by little with their footprints.

In some sections of the road, the footprints have been processed, but the level of processing is very poor. The four people watched back and forth, and arrived at the destination ten minutes later.

"The road here has been padded." Bai Song said with a heavy tone: "These scammers have a big picture. The road here can already allow professional off-road vehicles to pass."

"You mean, this road can lead directly to the crook's nest?" Sun Jie didn't understand, "On this road, how can the car run?"

"Yes," Bai Song said: "My friend Zhang Wei has been telling me about cars a few days ago. He told me that some heavily modified off-road vehicles have no difficulty passing through a bomb pit or a stone road. The road has been treated, If it were not for traffic, these trees would not need to be chopped down."

"Well, it makes sense," Sun Jie nodded, "If we want to carry out arrests, we must find a way to seal this road."

"Well, let's talk about it then." Bai Songyang raised the steel bar in Yang's hand: "Only this can't stop the off-road vehicle."

"Well, let's take a look at what these three people did." Sun Jie found a battery under a tree.

"Lithium battery", Sun Jie weighed the weight, only six or seven kilograms, "This thing is not cheap, this battery can store one or two kilowatts of electricity."

Many people don't understand the concept of electricity, they only know the milliampere hour of a mobile phone, but they don't know what the milliampere hour is.

Calculate with the electricity at home. A large mobile phone battery with a voltage of 3.7 volts and 5000 mAh can theoretically release 3.7 volts multiplied by 5 amperes and then multiplied by 3,600 seconds. This is expressed by the “degrees” of household electricity. That is 0.0185 degrees.

That is to say, regardless of energy loss, one degree of electric energy can fill more than 20 such batteries, which can fill almost 10 power banks.

One or two kilowatt-hours of electricity, this is already the storage capacity of the car battery, and it is enough for a hot pot meal.

A root wire was attached to the battery, all the way to the tree.

"Who will go up and see?" Wang Liang pointed to the five or six-meter-high tree.

"On the electronic equipment, someone claims to be an expert..." Wang Huadong was puzzled: "Huh? Who said that?"

"Cough, cough", Wang Liang touched his chin: "With my professional knowledge, electronic equipment, no matter what, I cut the wire and it's done once and for all..."

After finishing speaking, Wang Liang raised the pliers in his hand, wondering why he was so witty!

"..." Bai Song said with a black line: "If you want to cut it, you can say it, if you cut it, can they not know it? Besides, you dare to cut it without knowing it? What about the bomb? Or you can cut it. , Let's stay away."

Wang Liang looked at a few people eagerly, and everyone paid attention to him.

Climb...

Wang Liang is 1.78 meters tall and he is really not good at climbing trees, but he is always more flexible than Baisong's lattice. The three of them helped him and Wang Liang climbed up.

When he reached the middle section of the tree, Wang Liang saw a machine, clamped the tree with his legs, looked at it carefully, and slowly climbed down after ten minutes of fiddle.

After coming down, Wang Liang's legs were shaking so much that he couldn't stand still and sat down on the ground.

"What is it? I've been watching for so long." Wang Huadong asked.

"Remote control-on full-band jammer." Wang Liang took a breath and said word by word. After speaking, he slowly got up, holding the phone to observe the battery.

"You all know this?" Bai Song couldn't help being a little surprised: "Yes! But what is this thing for? Why did it take so long to come down?"

"I used my mobile phone to go online and read a few words..." Wang Liang scratched his face: "Hey, I haven't learned a lot of words..."

"Okay..." Bai Song nodded, "Why do you use this thing?"

"Interference signal." Wang Liang pointed to the battery: "This battery has been modified in series. It was originally a 12-volt battery. Now it has been converted into a 200-volt DC battery. The wire is also a copper wire for household AC.

The power of this device is as high as 3000 watts and is currently off. Once the remote control is turned on, a wide range of full-frequency interference can be achieved within half an hour. "

"In order to interfere with the cell phone signal?" Sun Jie looked at the surrounding barren mountains, "Why is it installed here? There is no signal around here, are you wrong?"

"Yes, yes," Wang Huadong vomited: "Maybe this is a signal gain amplifier. I guess the liar thinks the cell phone signal here is not good."

"Do you install this thing at three or four in the middle of the night? Are you so careful?" Wang Liang was a little speechless: "Just like you, you are still a policeman?"

Wang Huadong was too lazy to care about Wang Liang, and walked under the tree, "No matter what this is, he can't make it easy to use, and can't let these people know that we have done something, what's a good way?"

"This?" Wang Liang frowned, "It's definitely useless to install a wireless switch. Once this device is turned on, there is no difference. I install the wireless device, and the device loses its signal as soon as it is turned on."

"This is simple." Bai Song took the phone and took a close look at the power cord here. "This circuit looks complicated, but in fact it has three parts. The first part is the structure between the overall series battery and the machine; the second part is the current The signal structure is to test whether the entire system is malfunctioning; the third part is the remote control switch structure, which is actually connected to the second part and uses the original voltage of the 12V battery. It is actually very simple now. , The second and third system is always on, and the power consumption is very low. The first system is closed. The two main wires are now dead. Strip the shells of the two wires and expose them. Once the power is turned on It was short-circuited immediately."

"Okay, it makes sense. In this case, once it is activated, it will automatically burn." Zhang Jie looked around: "Will it cause a wildfire?"

"You have considered too comprehensively..." Bai Song thought for a while: "However, no, give me the pliers, and I will adjust the direction of the wires, so that if a short circuit occurs, it will automatically melt and contact the copper wire. , The power will be cut off automatically after fusing, there will be no fire hazard."

"You said, this is the only equipment here?" Wang Huadong asked.

"I don't know in the distance. There should be this one nearby. Don't underestimate the coverage of this one." Wang Liang thought for a while: "Generally, the power of the TV tower transmission tower across the city is only tens of kilowatts, and this jammer has three. Kilowatts, just compare it with you."

"Well, it's late, let's go back early." Bai Song pointed to the front: "One kilometer or so further, it is the scene where the life case happened tonight. Let's go back the same way."
