Therefore, Li Shan is very sensitive to the number 813, what it means, he knows very well in his heart, and this is seen in the police station, so it immediately aroused his vigilance.

He looked around, this office was relatively large, it belonged to the public office, and there were many partitions in it, and in each partition sat some other policemen. Everyone is busy with their own business, and no one seems to notice their side.

Li Shan sat back in his chair and moved it to the side, so that he had his back to the door. He held a pen in his right hand and pretended to write something on the paper, but his left hand reached forward, gently widening the drawer and leaning forward slightly until he could fully see the paper.

If someone appeared at the open door at this time, they could only see Li Shan writing something on the table, but they couldn't see the small movements under him at all.

The policeman should be back soon to pick up the printed papers, Li Shan listened intently to the movement at the door, and at the same time his eyes slanted down at the document in the drawer.

The first thing that catches your eye is the title of the document: "Notice on the Investigation of the "813" Case in Chang'an City", and the word "confidential ★" in the upper left corner of the document is clearly visible.

At this time, Li Shan's breathing was a little short, his heartbeat was also a lot faster, and the joint of the hand holding the pen in his right hand became a little white due to the force, but these did not affect the steady operation of his left hand, just like a veteran who had been doing it for many years.

Li Shan took a deep breath and quickly browsed down, the gist of this document is that at about 10:14 p.m. on August 13 this year, in the middle of Yanxiang Road in Chang'an City, a shooting occurred on the west side of the family courtyard of Xiguang Company, the suspect used a camouflaged pistol to commit murder on the spot, injured two people, destroyed a Land Rover off-road vehicle, and caused a No. 263 bus, including the car, and a small car, a total of three cars caught fire and burned, many people were injured, causing heavy losses of personnel and property.

ACCORDING TO THE ORAL ACCOUNTS OF EYEWITNESSES, THE PHYSICAL CHARACTERISTICS OF THE SUSPECT ARE ALSO DESCRIBED IN MORE DETAIL, AND THE SUSPECT SHOULD BE BETWEEN 20 AND 30 YEARS OLD, BETWEEN 175 CM AND 185 CM TALL, SPEAK MANDARIN, AND HAVE NO ACCENT.

Li Shan quickly browsed through these documents, but his ears listened to the movement outside, and he didn't care about the contents, and at the end of the documents were attached a hand-painted portrait of the suspect, as well as a color picture of the gun that appeared at the scene of the crime.

Li Shan had been watching for less than a minute, when he suddenly heard a rush of footsteps from far and near at the door. Li Shan guessed that the policeman should have returned, and immediately retracted the hand that reached into the drawer, and gently pushed the drawer in, but it was not completely closed, and still left a gap of about an inch.

The policeman came to the table with the printed materials in his hand, and did not seem to notice anything unusual.

He asked Li Shan to sign the papers he had just printed, and then pressed his fingerprints in the place he had specified.

When Li Shan walked out of the gate of the city bureau, he seemed calm on the surface, but his heart was extremely shocked.

Fortunately he saw the investigation report today, otherwise he would have thought that the police had relaxed their tracking of the incident, but he didn't expect the police to secretly strengthen the investigation.

How accurate the simulated portrait is in appearance, Li Shan, as the person concerned, is the most clear, although it is only a few strokes, but he completely outlines his own characteristics, but because the people in the portrait are wearing masks, it means that they have not mastered their true faces, so Li Shan is not too worried.

What shocked him the most was the picture of the toy gun, this picture is not a simulated picture, but a real photo, which is exactly the same as the one in his hand, why did the police have such accurate information about his gun?

Li Shan thought about it carefully, but guessed the reason for the incident. He speculated that the police might have drawn them by hand based on the descriptions of the injured people, and then took the pictures to the market, compared them with the real toy guns, and found the closest toy guns for witnesses to confirm, and after several iterations, finally confirmed the final shape of the gun.

At that time, those witnesses did see the gun in their hands, so it was not too difficult to find the same type of gun, but the color on the picture was blue, while his own one was green, only this point was different, and the others were basically the same. This may have been due to the light at night, which was mistaken for blue by those people.

It's scary to think about it now, if you don't know this, if you still have that modified toy gun to show around, in that case, it's only a matter of time before your whereabouts are exposed, nothing else, just how do you explain the problem about lasers when the time comes?

Thinking of this, the sweat on Li Shan's back came down.

What surprised Li Shan even more was that at the end of the investigation report, there was a special note, that is, the crime scene did not rule out the possibility of using too high-energy weapons, but no conclusive evidence had been found, and so far it was just some inferences.

After returning home, the first thing Li Shan did was to take out the laser gun, looking at the faint green light emitted from the gun, his hand caressed it, and he didn't feel the steely coldness, but there was a kind of warmth transmitted to his hand.

The scope and laser sight on the gun have been adjusted, and I don't know how much effort I have spent on this, although it is a pity, but now these can no longer be left, it is the only piece of physical evidence that can expose itself, and one more minute is dangerous!

So, Li Shan no longer hesitated, first took off the auxiliary equipment installed on it, and then disassembled the laser gun and took out the laser inside, everything else can be retained, but this toy gun can no longer appear.

This toy gun can't just be thrown away, it has to be destroyed first.

When I first bought this gun, I picked the best quality and the most expensive one, but now I want to smash it, and I can only endure the pain.

Li Shan smashed the toy gun into pieces with a hammer, then divided it into several parts, and threw them into several garbage cans in different locations along with ordinary garbage.

To be on the safe side, he took out the battery from the laser, and the laser became an ordinary laser pointer, thus avoiding unnecessary things from happening due to misoperation.

At this point, the last bit of evidence that could expose Li Shan also came to naught, and he breathed a sigh of relief.

Next, Li Shan had a feeling of emptiness in his heart, and he himself knew that the reason for this feeling was the laser gun that no longer existed.

The existence of that laser gun, Li Shan's heart has somewhat relied on it, and it is also where his confidence lies, and he has done some things that he can't usually do, so the top priority is to find a way to reuse this laser.

Transforming into a laser gun is obviously no longer feasible, and there is too much risk in it, so you have to find another way.

In the future, the transformed laser must not only hide its whereabouts well, but also exert the power of the laser. If you want to take care of both at the same time, the best way is to be able to integrate the laser into the drone, which is the best way Li Shan has thought of at present, and it is also the original intention of him to practice drone operation skills all the time.

Control the drone to strike at the target, but the operator can stay away from the scene, so as to maximize the protection of the operator, and the distance of the attack depends entirely on the performance of the drone, even if the drone is found at the scene, but it is not easy to find the controller behind it.

Based on the above advantages, Li Shan's determination to transform the drone has been strengthened, and now that the laser gun can no longer be used, it also makes his action of integrating the drone must also be accelerated.

At the beginning, when Lao Gu transformed the drone for himself, he had reserved a port, and the cable on it was the kind that could be easily plugged and unplugged.

Li Shan purchased some plugs from the electronic market, as well as crimping pliers, electric soldering irons and other related tools, and then drew two cables from the laser, and after installing the plugs, they could be directly connected to the socket on the drone.

The drone itself has an infrared emitter for practice, which is purely used to familiarize itself with and master shooting skills, and does not have the function of attacking.

In order to distinguish between them, Li Shan called the modified lasers capable of carrying out attacks attackers.

Next, you need to install this attack device on the drone, this attack machine is a little different from the original laser used for practice above, Li Shan has made some changes on the drone, and the attack machine can be installed on the drone.

The changes are relatively simple, and the operation remains the same as before, without being affected at all.

The next step is to adjust the camera, laser sight and attack vehicle on the drone so that the three can be completely consistent.

There are a few debugging skills that need to be mastered. Li Shan didn't bother to think about it anymore. So, he had no choice but to consult Lao Gu.

Although Lao Gu is a bit of a philistine, his craftsmanship is indeed good, and at the cost of paying two good cigarettes, Li Shan finally got the skill of debugging, and thinks that this time it is indeed worth the money.

Lao Gu's method is not complicated, but this debugging method focuses on its thinking, giving Li Shan a feeling of sudden enlightenment, if this method is used when debugging the laser gun before, it can achieve twice the result with half the effort, and it also provides a good reference and reference for similar debugging in the future.
