Defect another world

Chapter 549 Magical Items

This tension has long been thought about.

"So special bullets must be used. Just like in some legends, bullets made of ice? It melted and disappeared afterwards."

For the ice bullet, the tension has only been seen in novels.He had never seen the real thing.

"But ice bullets can't exist. Because ice is too brittle, it's impossible to shoot that far."

Fan Bu has done some research on this.

"You can use the same material as the window glass for bullets. Glass bullets have been used historically.

"However, glass bullets cannot be made to be exactly the same material as car window glass, and theoretically they can still leave flaws.

"It's just that it's actually impossible for the investigation by the Criminal Investigation Bureau to carefully analyze the composition of each piece of broken glass, and at most to sample a little.

"So the probability of actually finding glass bullet fragments is still very low."

"Then use some kind of mineral that dissolves in water. Like salt, and make the warhead. The warhead fragments melt in the water and disappear."

After Suzaku finished the barbecue, he started to drink and interjected with a smile.

"It's a good idea to use salt as a bullet. This way Locar's law of matter exchange is useless!"

Fan Bu said in amazement.

The so-called Locar's law of material exchange, which he regards as a divine law, means that whenever two objects come into contact, there must be a material exchange.

For example, if a bullet hits glass, there must be metal residues from the bullet on the glass.Trace amounts of glass are also bound to remain on the bullet.

But if the warhead is replaced by salt crystals, it will be more pitiful.The molecule of table salt is sodium chloride.Dropped into a lake it will dissolve.

Even if it would dissolve theoretically, traces of table salt could still be found on the shards of glass if more detailed analysis was performed.

But whether it is sodium ions or chloride ions, they are widely present in natural water bodies. What use do you find for them?
So even if there is an exchange of material, there may not necessarily be clues to the crime.The law of material exchange is still there, but it is no longer helpful to the investigation.

"But the modus operandi of this sniping is still not perfect."

Meng Fei imagined the scene at that time.

"The bullet hit the front window of the car, the debris flew, and there must have been a small amount of glass shards left on the road near the point where the water fell.

"If it falls into the water by accident, the car glass will not shatter in advance. So there will be no glass shards left on the road.

"You can tell the difference between the two just by looking carefully at the side of the road for shards of window glass."

"And if you're going to hit a vehicle with a sniper rifle, it's going to be on a hill by the lake, or it's on the road, or it's in the lake."

Mo Sheng denied the possibility of the sniping method from another angle.

"But the shortest straight-line distance from the place where the incident happened is three kilometers from the shore of the lake. Shooting from the mountain, there is no sniper rifle with such a long range."

"The road is closed to outside vehicles. There are cameras every kilometer.

"They checked all the surveillance footage and found no suspicious people or vehicles, nor did they see any suspicious boats on the lake.

"In fact, there was no sign of anyone else within three kilometers of the car that day.

"So not only is it impossible to snipe, but it is also impossible to release all kinds of interference to make the vehicle fall into the lake."

"Then is the driving system of this car safe enough? Maybe it was cracked and operated by the network!"

Chen Han moved out of his old business.

Now pure electric vehicles have assisted automatic driving systems, and the security system is very weak.

It is also completely feasible to crack through the network and remotely control the accelerator, brake and direction of the vehicle through the network.

"If so, the EDR system will record the data."

Meng Fei shook his head and continued.

"In fact, as long as the driver's consciousness is confused, whether it is frightened or falling asleep, this accident can happen."

Although he likes to drink beer very much, his alcohol capacity is extremely poor.After drinking half a can of beer, I already feel top-heavy and the world starts to float.

If he drives now, the probability of falling into the lake is 90.00%.

"It's not difficult if the murderer is not on the scene. It doesn't need to be as complicated as a sniper rifle or a cyber attack.

"Doesn't the general driver bring a big cup with a lot of tea?

"As long as the medicine is put in the cup in advance, the driver faints after drinking water, which may lead to this accident."

Meng Fei supported his heavy head and leaned towards his wife.

"If you just add medicine, it will definitely leave traces in the teacup. It is impossible not to be tested."

"Hey, what if instead of drinking, we use poison gas or something?"

Chen Han was inspired by Meng Fei's reminder.

"I've seen a movie before, where the killer puts a mechanism in the seat belt buckle. As long as it doesn't move, you'll be fine.

"When driving, if someone pulls out the seat belt buckle, the mechanism will be triggered, the poison gas will be released, and everyone in the car will be poisoned and unconscious.

"Then it wouldn't be strange to drive into the lake in the car, right?"

"But that requires agency control."

Meng Fei scratched his head, and exhaled a mouthful of alcohol-smelling white air into the cold night sky.

"If such a clever mechanism is installed on the car, it will be easy for the criminal investigators to see the problem.

"And the people in the car were all suffocated, weren't they?
"If it was caused by poison gas poisoning, or inhalation of narcotic drugs, the autopsy should also find out?"

"Correct."

Mo Sheng nodded.

"Neither a full inspection of the vehicle nor an autopsy revealed any particular device or traces of drug use."

"Even if there is a device, it may not be able to detect it, right?"

Chen Han did not retreat easily this time.Although this guy is usually not good at words, he doesn't like to back down during disputes.

"Maybe it directly used some device in the car, such as the air conditioner in the car, or it used something that the passengers brought themselves."

What Chen Han said reminded Meng Fei.

The murderer was not at the scene, and he was using something to cause an accident in the car.Then the stuff is either in the car or in the passenger's own belongings.

If things are going to be in the passenger's own belongings, it will take a very long-term planning.

Passengers' belongings are generally prepared before travelling, and then put into luggage.

At that stage, the "murder mechanism" is ready, it is difficult to control where the "attack" occurs, right?Even if it is a ticking time bomb, it can be easily detected afterwards.

In order to accurately create accidents, Meng Fei is actually more inclined to place devices or items on the car in advance.

In theory, the murderer should be very familiar with the characteristics of the vehicle, the route, the departure time, etc., in order to accurately realize the perfect crime.

So the things that really cause accidents should be placed in the car.

But the amazing thing is that the criminal investigators must have carefully inspected the vehicle, and the damage to the vehicle was not too serious, so nothing was found out?

Even if some toxic substances are released in the air conditioner and soaked in water, it is impossible for all traces to disappear.

Could it be that this thing is hidden in the passenger's belongings unknowingly, can cause accidents to the driver, and can never leave any traces?
What the hell has such a magical effect?
