Police Detective

In its implementation stage, simply speaking of on-site investigation, Sun Jie is definitely better than Huadong. After all, this is one of the duties of a forensic doctor, and the forensic doctor itself is affiliated with the on-site investigation department. It was just that Huadong took the initiative to ask for help, so Sun Jie didn't say anything.

The four of them followed the footprints and climbed up the mountain bit by bit.

On some sections of the road, the footprints had been treated, but the level of treatment was very poor. The four people were vigilant and arrived at the destination in ten minutes.

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

"You mean, this road can lead directly to the liar's lair?" Sun Jie didn't understand. "How can a car run on this road?"

"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 can pass through shell craters and stone roads without difficulty. The road surface has been treated. If it weren’t for traffic, there would be no need to cut down these trees.”

"Well, that 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 Song raised the steel bar in his hand: "This alone can't stop the off-road vehicle."

"Well, let's see what these three people did first." Sun Jie found a battery under a tree.

"Lithium battery", Sun Jie weighed it, only six or seven kilograms, "this thing is not cheap, this battery can store one or two kilowatt hours of electricity."

Many people don't understand the concept of power. They only know the milliamp-hour of a mobile phone, but they don't know what the concept of milliamp-hour is.

Let’s calculate using the electricity at home. A large mobile phone battery with 3.7 volts and 5000 mAh can theoretically release 3.7 volts times 5 amps times 3600 seconds of energy, expressed in “degrees” of household electricity. That's 0.0185 degrees.

In other words, regardless of energy loss, the electricity can fill more than 20 of these batteries at one time and can fill almost 10 power banks.

One or two kilowatt-hours of electricity, which is already the amount of electricity stored in the car battery, is enough for a hot pot meal.

There was a wire connected to the battery that went all the way to the tree.

"Who wants to go up and take a look?" Wang Liang pointed to the tree five or six meters high.

"Someone calls himself an expert in electronic equipment..." Wang Huadong looked confused: "Eh? Who said this?"

"Cough, cough", Wang Liang touched his chin: "With my professional knowledge, electronic equipment, no matter what, I will cut the wires, once and for all..."

After saying that, Wang Liang raised the pliers in his hand and wondered why he was so witty!

"..." Bai Song had a dark look on his face: "If I say it's cut, you don't have to tell me, can they know if you cut this thing? Besides, you dare to cut it when you don't know anything? What about the bomb? How about you cut it? , let’s stay away.”

Wang Liang looked at several people eagerly, but no one paid him any attention.

Climb...

Wang Liang is 1.78 meters tall and is really not good at climbing trees, but he is still more flexible than Bai Song. The three of them helped Wang Liang climb up.

When he reached the middle of the tree, Wang Liang saw a machine. He clamped the tree with his legs, looked at it carefully, and fiddled with it for more than ten minutes before slowly climbing down.

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

"What is it? You have been looking at it for so long." Wang Huadong asked.

"Remotely activated full-band jammer." Wang Liang took a breath and said word by word. After speaking, he slowly stood up and took his mobile phone to observe the battery.

"Do you know this?" Bai Song couldn't help but be a little surprised: "Okay! But what is this thing for? Why did it take so long to come down?"

"I took my mobile phone to browse the Internet and looked at a few words..." Wang Liang scratched his face: "Hey, I haven't learned a lot of words..."

"Okay..." Bai Song nodded: "What is this thing used for?"

"Interference signal." Wang Liang pointed to the battery: "This battery has been modified in series. It was originally a 12-volt battery, but now it has been modified into a 200-volt DC battery. The wires are also copper wires used for household AC power.

This device has a whopping 3000 watts of power and is currently off. Once turned on using the remote control, a wide range of full-band interference can be achieved within half an hour. "

"To interfere with mobile phone signals?" Sun Jie looked at the surrounding barren mountains, "Why install it here? There is no signal nearby. Did you read it wrong?"

"Yes, yes," Wang Huadong complained: "Maybe this is a signal gain amplifier. I guess the scammer thinks the mobile phone signal here is not good."

"Are you installing this thing at three or four o'clock in the middle of the night? Are you so careful?" Wang Liang was speechless: "You are the one who still wants to be a policeman?"

Wang Huadong was too lazy to pay attention to Wang Liang and walked under the tree, "No matter what this is, if we can't let him use it easily, and we can't let these people know that we have tampered with it, is there any good way?"

"This?" Wang Liang frowned, "It is definitely useless to install a wireless switch. Once this device is turned on, there is no difference. If I install a wireless device, the machine will have no signal as soon as it is turned on."

"This is simple." Bai Song took the phone and looked at the power cord carefully. "This circuit looks complicated, but it actually has three parts. The first part is the structure between the overall series connection of the battery and the machine; the second part is now The signal structure is to test whether the entire system is faulty; the third part is the remote control switch structure. This is actually connected to the second part and uses the original voltage of the 12V battery. Now it is actually very simple. The second and third systems are always on. It is on, and the power consumption is very low. The first system is turned off, and the two main wires are now out of power. If you peel off the shells of the two wires and expose them to contact, they will be short-circuited immediately once the power is supplied."

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

"You have considered it too comprehensively." Bai Song thought for a moment: "But no, give me the pliers and I will adjust the direction of the wires. This way, once there is a short circuit, the copper wires in contact with each other will automatically fuse and fuse. It will automatically cut off the power and there will be no fire hazard.”

"Do you think this is the only equipment here?" Wang Huadong asked.

"I don't know about the distance. This one should be the only one nearby. Don't underestimate the coverage of this one." Wang Liang thought for a while: "Generally, the power of the TV tower transmitting tower across urban areas is only tens of kilowatts. This jammer has three Kilowatts, you can just compare it."

"Well, it's getting late. Let's go back early." Bai Song pointed to the front: "About a kilometer further, we will see the scene of the murder tonight. Let's go back the same way."
