Wu Fan was still in the office, and Ah Jun had already left, leaving him alone, doing it in the office, he didn't have any expression on his face, as if this could make him feel that he was still alive, he raised his head, and his eyes were very deep.

"If you're still here, I don't know if you'll be disappointed, I'm leaving." Wu Fan suddenly spoke, his eyes were blurred, it seemed like he was talking to himself, he was thinking about something, he couldn't think clearly, he could only meditate.

Wu Fan is leaving at this moment, and what he thinks about the most is the case of the old policeman.

The old policeman has spent a year in order to investigate this case, and in this year, he has been collecting information and working hard, but this case has not been solved, and he knows that four months ago, Wu Fan came to this county.

When Wu Fan arrived on the ground, he took over the case.

"The criminals are going to be dealt with in a few days, and I think now we have to deploy the police to arrest the criminals." Wu Fan made this decision in a conference room, but this decision was not supported by others.

"Criminals have always been cunning, and we are doing this to surprise the snake, and we don't have any information about where the criminals are going to do it, so it's too hasty to do so."

"In this case, the police force of our police station is limited, if it is dispersed again, I am afraid it will cause more incidents, I think we are not too pessimistic, always feel that the criminal will appear, this year, the time for the criminal to commit the crime is almost two months to commit the crime, but this is only an approximate data, no one can accurately say the time, you see, the first time the criminal committed the crime was in July a year ago, in Lao Zheng's house, and the second case was at the end of August, and there was no interval of two months, look at the interval between the next crime in January this year, which is two months and six days, if the criminal is separated by another half a month, then we will deploy the police force for half a month in a row? ”

Obviously, everyone was very dissatisfied with Wu Fan's decision, they thought that Wu Fan was too radical, and this sudden big move was to startle the snake.

"My purpose is to scare the snake." Wu Fan said calmly, he can always say some surprising words, and now Wu Fan also said incomprehensible words, as soon as these words came out, everyone raised their heads in surprise, and their eyes naturally followed Wu Fan.

"Captain Wu, what do you mean by this, we really don't understand."

"Captain Wu, just explain it to us, there are reasons for doing this, I really can't think about it clearly."

Wu Fan looked at everyone, he was not in a hurry, he just silently wrote down a line on the whiteboard.

Everyone was puzzled, he looked at each other, and at the same time couldn't help but poke his head out to observe what kind of reputation this Wu Fan was doing.

After Wu Fan swiped a few big words on the whiteboard, he slowly turned around, and he said unhurriedly. "You see, this is the sign of a five-pointed star, I don't know if you have found it, every time a criminal commits a crime, it has something to do with the five-pointed star."

Wu Fan drew a five-pointed star on the blackboard, and also wrote down a line of numbers.

So the people present naturally looked at the whiteboard in unison, on this whiteboard, there was a line of numbers written by Wu Fan, as well as the five-pointed star pattern, and now, Wu Fan was pointing to the five-pointed star pattern.

"yes? Every time this pentagram criminal commits a crime, he will appear on the ground, and even, all of us say, this is the sign of his crime, but what does this sign mean? A policeman asked puzzledly, at this time, Wu Fan suddenly mentioned the pattern, is this suddenly related to the pentagram?

"It seems that there is no connection, but in fact, there are secrets hidden in this pentagram." Wu Fan replied that he implied that the five-pointed star was not just a symbol, and that the criminal was also sending some signal through the five-pointed star.

"Captain Wu, did you find anything? Tell us about it. The old policeman also spoke, he saw the confidence on the corner of Wu Fan's mouth, but he found out that Wu Fan has always cared about the pentagram, and he is also holding a bunch of numbers to compare, often just a person writing numbers in a daze, so he thinks that this Wu Fan must have made a breakthrough in the case.

Wu Fan listened to the words of the old policeman, he put down his hand pointing to the five-pointed star, turned around, swept over everyone present, he stood next to the whiteboard, condescendingly, and began to talk about the five-pointed star.

"The pentagram was first discovered in Mesopotamian texts, dating back to about 3000 BC. The Sumerian word for pentagram is a hieroglyph used as UB, meaning corner, angle, concealment, small room, hollow, hole, trap. Wu Fan talked about the meaning of the pentagram as if he was chanting a scripture, but when he said this, the people present still didn't understand it.

"Captain Wu, according to what you said, what are you trying to explain, do you want to tell us that this criminal compares himself to a five-pointed star, he is hiding, and he has set a trap for us?" A policeman interrupted Wu Fan's tirade, believing that what Wu Fan said made no sense.

In the Sumerian hieroglyphic dictionary, it also represents numbers...... 306。 Wu Fan didn't answer his question, and raised his voice, pointing back to the number he had written down as he spoke, "3, 0, 6." ”

Everyone was a little surprised, this Wu Fan's remarks were indeed novel, and now they were staring at the blackboard in unison, waiting for Wu Fan to explain closely.

"Let's take a look at another set of data, with a two-month cycle, the first case occurred in August last year, three days apart from September, and the second case occurred on October 1 last year, exactly two months, that is, the interval was 0, and the third case occurred at the end of December last year, six days away from the next cycle." When Wu Fan said this, he changed the number of months and intervals as he spoke.

“7~8，3”

“9~10，0”

“11~12，6”

“1~2，3”

……

"306, they all have an order in their intervals." A policeman was dumbfounded, and he was the first to stand up and speak.

"That's right, the interval between them and the next crime cycle is to cycle according to the three numbers 3, 0, and 6." Wu Fan said that he deduced this article, and it was also based on the comparison of several cases that he discovered the law, "According to this law, you can speculate on the time when the criminal will commit the next crime." ”
