fog city detective

Chapter 120: Beam Reasoning
Baker used to be a sniper, and he introduced and perfected Liang Xi's theoretical knowledge.For example, few snipers can hit medium and long-range targets with the first bullet after getting a new gun.Every sniper gets a new gun and will make fine-tuning on actual shooting.

Liang Xi asked the community police: "Is there a place nearby that is suitable for testing guns without being discovered?" It may not be accidental that things are hidden here.

The community policeman replied: "Yes, there is a small thermal power plant that was abandoned in the 60s three kilometers away from here. I often went there to play paintball games with my friends during my childhood holidays. However, due to the many cases of snake bites in the past few years The incident. The city hall placed warning signs on the road to prohibit vehicles and people from entering the thermal power plant. It is said that the Clement family intends to build a charity nursing home with [-] beds here."

Liang Xi said, "Let's go and have a look."

Liang Xi couldn't be sure if it was the hired killer that Baker said, but Liang Xi also believed that hiding things would not be a transaction. The hired killer fit the situation on the scene, and there was a certain possibility.I hid the sniper rifle at my grandma's house, maybe because there is a good place to test the gun.Assuming all speculations and guesses are correct, the target the killer wants to attack is by no means an ordinary target.

Not to mention the cost, etc., from the way of sniping, we can know that the killer has to face a target that is difficult to rely on traditional assassination methods.Residents can cause car accidents when they go out, and they can approach by asking for directions. No one can always maintain a very high level of vigilance.Residents driving can cause minor accidents such as rear-end collisions, and suddenly get shot when negotiating.Unless this person doesn't go out at all, he can only be dealt with by killing him.But otaku are usually kind people, who would use a sniper to kill an otaku?It is better to invite assassins from abroad than to pretend to be couriers or food delivery people to assassinate at home.

……

London is known as the city of smog, and the small thermal power has contributed a lot.Electricity is the foundation of industry. As an old empire at the beginning of the last century, Britain only began to pay attention to environmental protection in the 60s.They shut down many subway lines and subway stations, dismantled and abandoned many small thermal power plants.In the 80s, under tougher measures, London finally took off the hat of the fog city.

This thermal power station is a typical architectural style of the last century. A large chimney is clearly visible, and there are no more than two-story buildings next to the chimney.There are warehouses for hoarding coal, units for generating electricity, etc.The buildings are all made of concrete. Even though the thermal power plant is a hundred years old, no building collapsed in the wind and rain.

The building area of ​​the thermal power plant is not large, but the overall area of ​​the thermal power plant is not small, and there are concrete floors and small grasses that have broken through the cement everywhere.Some areas have been completely swallowed up by weeds.The community police told the two that snakes and insects appeared frequently in summer, so they should be careful.The police also explained that the hospital is equipped with basic serum, and under normal circumstances there will be no death.

The problem of viper serum is a social and commercial issue, as it is more expensive to produce and has fewer users.There are so many types of venomous snakes that lead to so many types of venomous snake serum that some countries need to airlift serum from other places, which delays the best treatment time for patients.But it is also unreasonable for hospitals to be fully equipped with venomous snake serum, because there are almost no users of many serums, and the serums can only be thrown away after they expire.Some people suggest that hospitals in a region prepare serum together, and when necessary, they can be deployed through the hospital. Due to the short distance between regions, this can shorten the time for serum injection.Since multiple hospitals share the cost of purchasing and storing serum, certain costs can also be reduced.

Liang Xi got out of the car, looked up at the [-]-meter-high chimney, and said, "Someone needs to climb up."

Baker asked: "Why?" Although he didn't like to think, he knew without thinking. If he chose one of the two, he must be the most suitable climbing candidate.

Liang Xi said: "Assuming it is a sniper rifle, the chimney is the only high point. Just check the dust accumulation on the ladder to know if anyone has climbed the chimney recently. If not, we are faced with countless possibilities. If so, We can not only confirm the existence of the sniper killer, but also infer the height difference between the killer and the target."

The old-fashioned chimney of this thermal power plant has ladders in both east and west directions.It is a very narrow zigzag ladder, and there are many inspection openings when walking upwards, which is convenient for the staff to inspect the smoke exhaust pipe and deal with the dust accumulation.

Liang Xi said: "Both stairs have to be climbed. If we are right, a shooting hole should be dug out." Assuming that the height difference between the assassination target and the sniper's position is 200 meters, then there is a killer at 200 meters Excavated firing holes.If you don't find it, let's wash up and sleep.

Liang Xi is quite confident. This set of speculation is one step after another. Each step is uncertain, but each step is the choice with the highest probability.

If the intruder doesn't steal anything, there are other possibilities, and the possibility of hiding things is the greatest.Find a sofa through this assumption.The possibility of the transaction was denied based on the child's two eyewitness testimony two days apart, and Baker's killer theory is the one that most fits the situation at the scene among all possibilities.Based on this statement, a thermal power plant was found.

Inviting snipers from foreign countries shows that the security of the assassinated target is tight, and the snipers are likely to shoot at the target from a height.Snipers need to try and fine-tune their guns. The chimneys of thermal power plants are not the only choice, but they are the best choice.The gun is hidden near the thermal power plant, which should be related to the need for a test gun.

This is the deductive method, inferring the Pacific Ocean from a drop of water.However, Liang Xi's deductive method has an error rate, because Liang Xi believes that there are too many possibilities in this world.Assuming that Liang Xi needs to climb the chimney, he can find a hundred reasons to kill the deductive method.

……

"Hello Baker." Liang Xi answered the phone.

"Find a shooting hole." In front of Baker, there is a large hole with a diameter of 20 centimeters, facing the north direction.

Liang Xi said, "Baker, use your binoculars to see if you can find something like a target."

Baker said, "The binoculars are in the car."

Liang Xi said, "Then come down and get it."

Baker asked, "Can you bring it up?"

Liang Xi asked, "How tall?"

Baker replied: "About 100 meters."

Liang Xi: "Trust me, you get it down 10 times faster than I send it up."

……

Baker took a telescope to observe for a while: "A piece of wood fell on the ground." Such a clean and tidy piece of wood seemed out of place in the messy wasteland.

Liang Xi drove the car and arrived at the wooden strip under the guidance of Baker. Liang Xi got out of the car and saw a 40 cm wide wooden strip fracture mark: "We need measurement data."

Baker asked, "Would you?"

Will it or will it not?First measure the distance from yourself to the chimney, then measure the distance from the chimney to Baker, forming a right triangle.After obtaining the lengths of the two right-angled sides, the distance of the third side can be calculated.

Baker judged based on his own experience, and said: "I think this is a sniper kill where the shooting location and target location have been determined. The visual inspection is about 800 to [-] meters."

"You interrupted my train of thought." Knowing two sides, how do you calculate the length of the third side? 3.14?That's pi.How do you calculate it?Fuck!Liang Xi said: "We have to get the measurement data first, we need support." We must not reveal the fact that we don't know how to calculate the side length.Liang Xi said, "Can you test the gunpowder smoke reaction?"

Baker was silent for a moment: "The test paper and test fluid are in the car."

So Liang Xi drove back to the chimney. Baker took the test paper and test fluid and climbed the stairs again. The accompanying community police contacted the fire brigade and asked them to bring tools to help measure a set of data.

Baker called: "Smoke response detected. Your guess is right."

Liang Xi corrected: "It's our speculation. If you don't have a reminder, I won't think of weapons." I won't think of weapons so quickly.

……

The total station is a cow, skipping the calculation link directly, and concluded that the distance from the wooden bar to the shooting hole is 806 meters.Even then measure both sides.The distance from the batten to the chimney is 800 meters, and the height of the firing holes is 100 meters.

Then Liang Xi had no idea, which was far beyond his ability.Today was the first day Liu Zhen went to work in the anti-terrorism office. Liang Xi contacted Liu Zhen: "There is a sniper who wants to shoot a fixed target about 800 meters away. It is speculated that this target is difficult to assassinate with ordinary attack methods. The bad guys used A lot of thought has been paid to recruiting a sniper from abroad. The first one may be a prison, where there is a time of release and the defense is tight, and it may be a felon in solitary confinement."

Liang Xi said: "The second one may be political leaders. Their cars are bulletproof and their residences are tightly guarded. Baker told me that it takes about a second for a sniper bullet to hit a distance of 800 meters. Long-distance sniping is difficult to predict in advance." Judgment. The target comes out of the office building, unless you keep him still for more than a second." Close-range sniping basically does not need to consider the flight time of the bullet.It is very difficult to hit the lead time at a long distance.

Liang Xi said: "We don't think there are many chances of gunfire, maybe only one or two shots. I speculate that the third possible target is important witnesses or criminals in the safe house. These people are active indoors on a daily basis, surrounded by armed forces. I will definitely go out to let the wind out regularly every day. Judging from the clues we found, this goal should be very important."

Liang Xi said: "The above is the information we can provide. For the time being, the forensic personnel have not been notified to go to the thermal power plant to collect evidence. Now look at your opinion. If you have no ideas, Baker will contact the forensic and hand over the case and the scene to the police. Investigate."

Liu Zhendao: "I will contact you later."

In front of Liu Zhen was a short-haired, one-eyed man in a suit, about 50 years old, with a fierce face.Cyclops pondered Liang Xi's analysis repeatedly in his mind, and said, "I'll make a few calls."

Liu Zhen nodded and left the office.

After 10 minutes, Liu Zhen was called to the office. Cyclops quietly watched Liu Zhen take his seat, and said, "I found it, Luke." Arrested, and Blade later took over the case.

Cyclops said: "Sir Luke is willing to cooperate with the prosecution and become a tainted witness. He is willing to testify against a big man and a certain chaebol in a scandal in exchange for his own freedom. I don't know who the big man is, and the blade doesn't know They told me that they dispatched two groups of red and blue Shuanghe special police directly under the blade to the safe house. There are three high points of about 750 meters in the safe house where Luke is 850 meters to [-] meters. I told them that I am not sure Whether Luke was the target or not. They wanted me to give the sources and let them judge for themselves."

Cyclops said: "Do you think you should tell Blade who provided the information?"

Liu Zhendao: "I must seek his consent."

Cyclops signaled, Liu Zhen called Liang Xi, and Liang Xi said, "Hello, beauty."

Liu Zhendao: "Liang Xi, Dao Feng wants to contact the information provider."

Liang Xi said, "It's best not to."

Liu Zhen asked: "Why?"

Liang Xi said: "The money they give is too little. You can handle it yourself, so I will find out here. Anyway, it must be a big shot, and I don't feel sorry for whoever dies." There is a shortage of blue-collar workers, doctors, and medical staff these days. There is no shortage of teachers...but no shortage of great men.

Liu Zhen asked: "Will they give money?"

Liang Xi said: "I'm not very short of money at the moment. You said that the supreme parking lot, I didn't take a dime from them. Besides, Monica and Luke, I still didn't take a dime from him. After so many cooperations, only Once, I asked for it on my own initiative, and I came to the door to collect it, and they only gave it for three hours. The money is too embarrassing. Besides, I also accepted the commission here."

Liu Zhen asked: "Consignment? How much?"

Liang Xi: "It's not a matter of money. He is my regular customer, so I have to accept it when I come to my door."

Liu Zhen: "Okay, let me handle this matter."

Liang Xi replied, "Okay."

Liu Zhen hung up the phone, and Cyclops contacted Yisha: "Isha, I think you'd better change places. Goodbye."

After hanging up the phone, Liang Xi called Liu Zhen, who said, "Hello."

Liang Xi said, "Captain Liu, are you in charge?"

Liu Zhen: "Well..."

Liang Xi said: "If you are in charge, I will just talk a little more nonsense."

Liu Zhendao: "It has something to do with me."

Liang Xi said: "Thresh met with me before leaving London, and pointed out that a violent criminal gang is about to do things in London. I guess Thresh may have a certain relationship with this gang. Based on what I know about Thresh's style, you also I know, Thresh is best at sniping and killing people with knives. The Mi5 warehouse can’t find it, so they beat the grass to scare the snake. If the fans can’t do it, they kill people with knives. Could it be... I don’t know who the target is, so it’s hard to guess.”

Cyclops nodded to Liu Zhen, and Liu Zhen said, "It may be a witness detained in a safe house."

Liang Xi said: "Then you have to be careful, because the safe house is tightly guarded and cannot be breached, and you deliberately set off an alarm to force the relevant departments to transfer the witness out of the safe house. Besides, if it is a safe house, your trouble It’s big. Obviously the killer knows the location of the safe house. According to my understanding, not many people know the safe house, and there may be ghosts among these people.”

Liang Xidao: "A safe house of this level can still reveal ghosts, isn't the witness particularly good?"

Liu Zhen reminded: "Monica."

"Fuck, it can't be Luke, right? This is a big dragon! He must be a fairy-level person to expose." Liang Xi said: "I can only wish you good luck. Quietly, stay away from Luke This kind of big guy may not be able to force others to directly launch a fighter. The sniper is just a small test, and if he can't kill Luke, the big guy will definitely jump over the wall. Once a person jumps over the wall, he will use any means."

It seems that Luke is not a smart person, but he is willing to expose others.Or Luke is smart: If you don't get me out, I'll kill you.The other party thought, I want to see if I can kill you first.This may be full of political games, and it should be very exciting.It's a pity for Luke, but no matter how good a character is, he will overturn on a woman. From ancient times to modern times, the same examples abound.
