Chapter 160 Genius

◎Complex dynamic mathematical model◎

Zhao Xiangwan asked Gou Changan: "Is this your first action?"

Gou Changan nodded: "Yes."

Zhao Xiangwan asked: "Where's the intercom?"

Gou Changan replied: "After driving out of the alley, the man instructed me on the walkie-talkie to drive the motorcycle to a trash can on the corner of the street. There was a black plastic bag in the trash can with the remaining 5,000 yuan. Then, I threw the walkie-talkie into the trash can as instructed, picked up the plastic bag and left the scene."

Zhao Xiangwan asked: "Is the money new? Are the numbers consecutive?"

Gou Changan shook his head: "No, they are all old banknotes."

"Are there any characteristics of the bag or envelope containing the money?"

"No, just the ordinary envelopes and black plastic bags you see in stationery stores."

One action, one walkie-talkie, and no one showed their face.

Fingerprints are unlikely to be left on the banknotes.

The other party acted very cautiously.

Zhao Xiangwan asked: "The robbery that happened in front of the city's children's hospital in August had nothing to do with you?"

Gou Changan shook his head hurriedly: "No, no, it has nothing to do with me."

It seems that Gou Changan has only participated in two operations so far, and the Peng Qianze case was the first time he followed the orders of the mysterious man.

In the deep alley, Gou Changan was a little nervous and acted nervously and cautiously. After finishing the job, he left quickly without even looking back. After getting the money, Gou Changan kept lying to himself: I was just joking, the little leader with a briefcase under his arm just fell down, it's nothing.

Zhao Xiangwan heard what Gou Changan was thinking and knew that he had always been feeling lucky. He raised his eyes and looked at him with a cold voice.

"That man, Peng Qianze, is not a leader, but an ordinary technician in the Inspection Department of the Food and Drug Administration. He has a wife and a son. His company is building a collective housing unit, and the family has been saving money to buy a house. He now lives in the dormitory assigned by his wife's company. If he takes the bus after get off work, he has to go three stops. Peng Qianze is reluctant to spend the bus fare, so he insists on walking home every day."

Gou Changan's heart sank.

Is he so poor?

[He is not a leader, he is not even willing to take the bus. ]

[It’s worse than my life! ]

Feeling guilty, Gou Changan looked at Zhao Xiangwan and asked cautiously, "Then... is he okay?"

Zhao Xiangwan shook his head: "Because of your action, Peng Qianze fell to the ground and was crushed to death by the truck driver who drove into the alley from behind."

Gou Changan clenched his hands tightly together, his knuckles turning a little white, and it was obvious that his emotions were very turbulent.

[Dead! ]

【Just like that, he died. 】

[Another life! ]

The scene of Qi Wanjuan and her daughter being hit flashed through Gou Changan's mind.

If Chang'an could bury his head in the sand like a camel and pretend not to see anything when carrying out the mission for the first time, he could no longer pretend to be ignorant when carrying out the mission for the second time.

He watched the BMW hit the guardrail and left excitedly. The motorcycle was speeding on the road. Thinking of the BMW driver's ferocious look, he was extremely happy and shouted in his heart: Done, job done!

However, that night, Gou Changan saw a news report on TV.

The scene was in a mess and covered in blood.

The mother watched from the side and wiped away tears: "Damn the driver, he hit someone to death! The mother died on the spot, and the child was still being rescued, so pitiful."

The scenes on TV made Gou Changan's excitement disappear, and the joy of easily earning 10,000 yuan was soon replaced by fear.

Zhao Xiangwan's eyes were deep as he continued to ask about the follow-up.

If Changan continues to speak.

Half a month later, the other party knocked on his door again, with the same routine, the same 5,000 yuan deposit, and the same intercom. The only difference was that no words were left.

The other party seemed to have reached some kind of tacit understanding with Gou Chang'an.

——I give you the money and you do the work.

Gou Changan followed the mysterious man's arrangements and waited at a certain street corner at a certain time, waiting for the other party's instructions.

On the first day, he arrived at the intersection of Jiefang Road, and what he was waiting for was a cold reply: "Call it home, and go home."

The next day, he waited at the street corner again, and what he got was still the same: "Call it a day, go home."

It wasn't until the third day, the day of the car accident, that he finally waited for the mysterious man to say "1, 2, 3, go!"

So, Gou Changan started the car and drove straight forward.

"Get close to that precious carriage and push it towards the guardrail!"

"Very good, call it a day."

"Speed ​​up, get out of here, don't look back!"

"Stop, there's a blue trash can on the side of the road."

Just like that, Gou Changan threw down the walkie-talkie and got another ten thousand yuan.

After he finished explaining everything, Zhao Xiangwan stared into his eyes with a cold look: "Ten thousand yuan for a life. Is human life so worthless?"

After hearing what Zhao Xiangwan said, Gou Changan's face turned pale and he didn't dare to respond.

【Ten thousand dollars, one life! 】

[I was just riding a motorcycle and following that man's orders, and I killed two people.]

[Does this count as murder? I won't be shot, right?]

Gou Changan also realized the seriousness of the problem at this time. He raised his eyes and looked at Zhao Xiangwan steadily: "Comrade police, I... I didn't mean to do it. I didn't know that this would kill someone. I thought it was just a prank."

Zhao Xiangwan raised his lips slightly and said sarcastically, "You think it's just a prank to give money to your door for no reason? How long will it take you to earn 10,000 yuan? You can earn 10,000 yuan just by riding a motorcycle on the road. Can you feel at ease with it?"

Gu Chang'an was speechless for a moment and could not respond to Zhao Xiangwan's words.

To be honest, he actually had some thoughts in mind.

Of course he knows how hard it is to make money in this world.

Suddenly, he got a fortune, but he couldn't sleep or eat well, as he always felt that something was wrong.

Gou Changan tried to make amends: "Comrade police officer, I didn't touch the money. The manila envelope has been kept at home. I spent more than 2,000 yuan of the first 10,000 yuan I earned to take my mother to the hospital for treatment, and I saved the rest. I will pay it back, all of it! I will find a way to make up for the money I spent. Don't worry, I will definitely make it up."

Gou Changan dropped out of school early and had no special skills. He supported his family by doing some private work on the street on a motorcycle. Because he had been struggling on the poverty line, he hated the rich very much.

In his opinion, rich people driving luxury cars and officials carrying purses are not good people. Therefore, he had no objection to the mysterious man's order. However, he felt guilty for killing an honest man who was reluctant to take the bus to save money and a good reporter who was helping ordinary people.

Gou Changan tried to save the situation: "Oh, right! The man sounded young, and he spoke standard Mandarin."

Zhao Xiangwan: "How standard is it? Is it the same as for TV announcers?"

Gou Changan shook his head: "Not really, not as standard as a broadcaster, but better than most people. Although there is often a crackling sound from the electric current in the intercom, you can still tell that it is a man, not an old man, and speaks good Mandarin."

People from Hunan Province speak with a heavy accent and cannot distinguish between Hu and Fu.

The fact that the man could make Gou Chang'an feel that he spoke standard Mandarin might be a clue.

Ji Zhao was listening at the side, when suddenly his eyes lit up, he stood up, spread out the map of Xing City, and marked two crime scenes.

[Xiang Wan, ask him, during the entire process of the accident, when was the sound in the intercom clearest and the noise the least?]

Zhao Xiangwan stood up, holding a pencil, and compared the location on the map, asking Gou Changan in detail where the sound came from and what the sound quality was.

"Which street corner are you waiting at? Is the voice quality clear when the other person speaks?"

"When did the other person start talking? What did he say? Was there any noise?"

"Which road were you on when you got close to the BMW? Was there any noise?"

"Which street corner is the trash can? Can you hear the voice coming from the intercom clearly?"

Gou Changan recalled it seriously.

Ji Zhao closed his eyes, and his mind quickly flashed through everything he saw when he and Zhao Xiangwan rushed to the intersection of Jiefang Road Primary School.

Jiefang Road intersects with Tongren Road.

There are many high-rise buildings along Tongren Road, including Lutong Bank, Jiefang Bank, Jinsui Bank and many other banks, as well as a large supermarket and dozens of six-story brick-concrete residential buildings.

Jiefang Road is dominated by parks, schools, and residential communities, including the scenic Jiefang Park, Jiefang Road Primary School, Jiefang Road Middle School, two high-end residential communities, and a chain hotel.

The people who command Chang'an are in this area.

He was able to monitor Gou Chang'an's actions at any time, and at the same time pay attention to the BMW owner and Qi Wanjuan's every move, give instructions in time, calculate the direction and speed of everyone, and use an unexpected factor "motorcycle" to push the incident towards an unexpected development.

This is like a game of chess. Everyone's actions are both accidental and inevitable.

Qi Wanjuan picks up her daughter from school every night; it's a must.

Her speed and direction are roughly fixed.

Countless cars drive on the road every day, at unknown speeds, and their reactions to unexpected situations vary.

However, this person was able to rehearse the trajectories of countless people in his mind, and build a huge mathematical model in this originally normally operating system. Then he added a disturbing factor and, through the sudden addition of a chess piece, he finally created a perfect murder plan.

【This person is a mathematical genius. 】

【Quantitatively describe the laws of matter and motion through mathematical modeling. 】

Ji Zhao's words shocked Zhao Xiangwan.

Math genius?

Mathematics is the science that studies the spatial forms and quantitative relationships of the real world.

A mathematical genius can unlock countless mysteries of the universe.

In any country and at any time, the existence of mathematical geniuses will promote the development of science and technology. Such talents are extremely precious.

Zhao Xiangwan's heart was filled with confusion and anger.

Use the power of mathematical modeling to carry out inhumane murders!

Why do people with such a rare talent not create wealth for their country and the world, but instead lead murders?

Ji Zhao opened his eyes, took a piece of white paper and started painting.

Ji Zhao is also a genius.

He drew a realistic perspective map of all the areas within his sight, with the intersection as the center.

Based on Gou Changan's description of the intercom commands, sound quality, and noise, three positions were eventually locked.

A residential building;

an office building;

Qijia Hotel.

【The mastermind is standing right here.】

【The mastermind must remain still and cannot move. 】

【If he moves, all factors will change, so he must remain still.】

Jiefang Road is the main traffic artery in the central urban area of ​​Xingcheng. At dusk that day, there were not many cars, but there were quite a few pedestrians.

Everyone does their own thing.

Children were crossing the street chattering and laughing.

The parent walked out of the school gate holding his child's hand.

Crowds of people are rushing home after get off work.

There were hundreds and thousands of people appearing in front of the eyes at the same time.

The movement trajectory of every person and every car is a line, with time as the axis, forming a complex dynamic mathematical model in the entire space.

How much calculation is required to connect all of this together, and to cause the BMW to lose control and hit Qi Wanjuan accurately with just the provocation of a motorcycle?

Even if the largest computer in the world were used, it would still be impossible to complete the calculation in just a few minutes.

Unless, this person is a genius.

His brain works faster than a computer, so fast that it's terrifying!

However, there is also a prerequisite here.

This person must maintain a stable observation point.

If he moves, all mathematical models will have to be corrected, and the final calculation results will be biased, which means the action has failed.

Based on the clues, Ji Zhao circled these three points on the map.

Zhao Xiangwan's eyes sparkled with excitement, and he immediately reported to Xu Songling: "Director Xu, send people to these three places to interview the people around them. Did they see a man talking on a walkie-talkie at the time of the incident?"
