"Yang Hang, let you be in front. Hide from you, let me die first. ”

"Yao Zhewei, don't play if you don't know how to move, professional pit teammates. ”

Chen Xiaoying shouted, the two brothers were commanded by her, and their performance was even worse.

Yang Fan saw his cousin playing games with a gloomy face, he should have endured to the limit, Yao Zhewei was easy to speak, and deliberately made mistakes again and again.

A bunch of troubled teenagers and boys.

Yang Fan is proud, my brother is out of the level of a child, look, the game is not interesting at all. Yang Hang's room is familiar to him, and he often slept together when he was young a few years ago.

He went to the printer and pulled out some blank sheets of paper, and took a pencil from the bedside table drawer. The three of them sat on the mat, and they glanced at this brother, what do you like, the mobile phone operator has no time to talk.

Back in the living room, opening the map on his mobile phone, Yang Fan said, "Brother Tian, how are the seats of the seven crime points distributed?"

"Yang Fan, are you really here?"

"What the hell, you still know how to solve cases?"

Yang Fan didn't speak, referring to the map of Beiqiao, drawing with a pencil on the paper, and with a few strokes, the main road of Beiqiao Town was drawn.

The hand does not stop, adding branch lines, side roads, assigning commercial areas, residential areas, first-class industrial areas. From scratch, the image gradually plumps up and is completed in less than three minutes.

"What a powerful memory?"

Several men gathered their heads in a heap and watched as he finished the map. Tian Jian has been studying this map for more than half a year, and he can't be more familiar.

If you let him draw it, it's probably no problem, but like Yang Fan, it will be perfectly displayed after a few glances, and it can't be done at all.

"It's a bit of a doorway, Yang Fan. ”

Chen Shifei saw the sense of beauty, and how the sense of beauty came about was precisely proportioned. From the beginning of the pen to the finish, the pencil has not been modified in the hand, and it is done in one go.

"The regulations are clear, the longitudinal and horizontal, it's just a sketch from above, and the real map is enlarged. Chen Shifei was amazed by this, just this ability to draw with his hands, he could eat outside.

Yang Fan was embarrassed by the praise, scratched his head, and said, "Fooling around." Brother Tian, please report the location of the crime, and I'll try to calculate his residence or the location of the crime next time. ”

Calculations? Can crimes still be calculated?

I just said random, didn't you understand?

Tian Jian thought about if he was a criminal, would he set and calculate in advance when he would commit the crime?

No, the single woman walks alone at night, the probability is very small, and after the wind is tighter, the police force has been ambushed many times late at night, and the suspect has not appeared, and he has committed the crime again after the limelight, which is extremely cunning.

Seeing that his cousin didn't seem to be joking, and his family didn't obviously object, Tian Jian remembered that he also had the title of a mathematician, talking about being born in nothing, and pointed to a certain point on the sketch: "At 13:12 a.m. on November 15 last year, the first crime was committed in Guangfei Road and Liujiaxiang......"

"At 15:21 a.m. on June 7 last month, in ......"

7 crime locations, replaced by circles with a radius of one millimeter. Three are in the southeast corner and four are in the northwest corner.

If the 7 dots are circular, the suspect is most likely to live in the middle zone.

Right now......

As a guessing game, several big men came to be interested.

"If you arrange the two levels and circle the location, will it be the middle of the straight line between the southeast and northwest?"

"It won't be that simple, Oda said that the suspect is cunning, this should be a deliberate inducement, he may be in the northeast blank, or he may live in the southwest. ”

Yang Tian saw his son Yang Fan bowing his head and muttering silently, afraid that the latter would not be able to get off the stage, so he said: "Don't be reckless, we ordinary people, what are you doing with this heart." With the government's action, it won't take long to catch people. ”

"Yes, tea, smoking. Tian Jian helped them add tea and gave out a circle of cigarettes.

"No, there is a pattern. Yang Fan's eyes were condensed, and after thinking, he started writing again.

"What?

Tian Jian subconsciously followed his finger to look, only to hear Yang Fan say as he wrote: "According to criminal psychology, when committing a crime, you must be familiar with the surrounding environment, and stay away from the house to prevent exposure. Then, the distance is between 500 meters and one kilometer. ”

7 dots spread, and according to the proportions, seven hollow circles are drawn. Three crossings cover 6, four crossings cover 5, and when the last circle is drawn, the most crucial place appears, there, there are five circles crossing.

"How can it be so round?" Chen Shifei gasped, the aesthetics were different, he saw the beauty of the circle, as if it was drawn with a compass, which reminded him of Leonardo da Vinci's painting of eggs, his arms were steady and powerful, and his painting was tempered.

How did he judge the ratio of 500 to 1 kilometer?

"Is it here?" Yang Tian pointed to the intersection at most.

"Hey, isn't that the middle section of the two places I just mentioned?" Yang Yuan was overjoyed, feeling good about himself and having an IQ online, "But it's still not as clever as his nephew Yang Fan, who has made the location more accurate." ”

Yang Yuan praised himself and his nephew again, and his face suddenly turned red, and he could still help my prospective son-in-law, killing three birds with one stone.

Tian Jian glanced at that location, slightly disappointed, too young to understand how powerful the police system is.

"Xiao Tian, has this piece been checked?" Yang Tian asked for his son.

Yang Fan's brows furrowed deeper and deeper, he still didn't feel right, something was missing?

"The police criminal psychology expert and behavioral expert came to a similar conclusion to Yang Fan, that it was a radius of 100 meters, just two company dormitory buildings, so it can be said that we dug three feet into the ground and did not gain anything. Tian Jian's face was expressionless.

In the fifth case, the crime site was from the southeast to the northwest of Beiqiao Town, and the criminal police squadron celebrated with a crown, thinking that it had caught the suspect's little tail.

Reality gave them a resounding slap in the face, and after checking it five times to no avail. In the dormitory building, after the employees went to work during the day, the criminal police blocked the scene, called a private locksmith, and checked the large and small boxes.

It's embarrassing, isn't it, mathematicians haven't made a name for themselves.

Yang Tian coughed, pretended to look at the electronic clock on the wall, and said, "It's past nine o'clock, or it's going to disperse." I went back to take a shower on a hot day. ”

He gently kicked his son's buttocks, who was thinking on his stomach, and pretended to be forced, so let's run.

"Dad, what are you doing?" Yang Fan was inexplicable.

"My family was sleepy and went home. ”

"Yes, we'll see you another day. ”

"That's right. Yang Fan hurriedly added two small black dots to the map, looked up at Tian Jian, and said, "Brother Tian, these two places will be the place where the crime will be committed next time, you can ask someone to ambush in advance." ”

Handing over the paper, Yang Fan stood up and ran to his grandmother's room.

When the light was turned on, the old man was already asleep, so he waved his hand and said nothing.

"My aunt is gone. ”

"Uncle is gone. ”

......

Tian Jian studied the remaining two targets, and the more he looked at it, the more confused he became, isn't this a fool, the two places where the crime was committed were added, and the difference between them seemed to be less than 100 meters from the sixth time or so.

The suspect is not mentally retarded.

A large group of people were greeting each other and preparing to leave, Tian Jian sat on the sofa, his face struggling violently.

"Wait. Tian Jian held on to the last glimmer of hope and stopped Yang Fan at the gate, "Little brother, it's not that I don't believe you, there must be a basis for arranging the police force, I can't convince the team members, what should I do as the team leader." ”

Don't say that he doesn't believe it, the family members hear it very clearly before and after, and they are also skeptical.

"If you are really famous, talk to your brother Tian. ”

"That's it, you little bastard, what do you mean by hiding half of your words?" Yang Xi pinched Yang Fan's ears, who is the boyfriend and his younger brother, this point in time must be a boyfriend.

"Okay. ”

Yang Fan took back the paper on which the map had been drawn from Tian Jian's hand, folded it back in half: "Brother Tian, look at it again." ”

The white paper, facing the light, the nine small dots, strangely familiar.

"It's ...... Beidou?" Tian Jian was shocked.
