The first time I wrote a serial case, I was stuck in my dreams at night solving cases! Lasagna tears......

I'm stuck! TAT

------Off topic------

This is crazy!

The more Zheng Guangqi listened, the more frightened he became, "This, this ......"

Twilight beckons to him, asking him to come over and whisper in his ear.

"Huh?" Zheng Guangqi opened his mouth, thinking that he had misheard.

"All you want is for your people to be stunned!" Twilight was shocked.

Zheng Guangqi was only worried that he would startle the snake, but when he heard this, he suddenly became even more excited, "Yes, the murderer has medicinal powder on his body, and if the people who are in charge are also stunned by him, won't they be able to catch him?" ”

Sure enough, she was still calm at the last moment, and at this moment she explained: "This is impossible. This murderer is a pleasure-type killer, with a collector's habit, that is, he is addicted to committing crimes, and he kills people to experience pleasure, so even if he knows that there is danger, he can't help but commit crimes again. And what he collected was the blood of Shougong Sand and Virgin, so he just wanted to change the type of people to kill, and there were no conditions for committing crimes, and most of the people who went out at night were Qinglou women. And he is a master of art and bold, he has a dizzying medicine powder on his body, even if he knows that there is an ambush from the government, he is not afraid. If he commits a crime in the net laid by the government, I think he will be even more excited! ”

"If the lower officials strictly ordered the young children sold by the four green houses in the future to report to the government, would the murderer know about it? If he hides and doesn't dare to commit another crime after learning about it, or kills someone else, wouldn't it be ......" Zheng Guangqi looked at Twilight Qing, he had followed Twilight Qing to investigate a few cases, and had already figured out how to get along with her, that is-no matter how poisonous she is, I am cheeky! As long as you don't put on official authority, you don't care about face, and if you don't understand something, you can ask for advice bluntly, and you will definitely be able to gain something.

"What?"

"Yes, yes, the lower officials are taught." Zheng Guangqi bowed his mistake and raised his sleeve to wipe the sweat on his forehead, this spring season, he was sweating all over, "However, there is one thing...... Xia Guan was a little worried. ”

She returned to the city for two days, and if the murderer could be found and arrested by the conventional method of investigation, she would not have to use this method. However, when she took over the serial case, it was already the fourth, and the scene of the first case with the most clues had been destroyed, and the two-day investigation time was too short after all, so she had to use this method.

"Wrong! The point in this law is 'next crime'! The next crime represents the next victim, the next person who may be brutally murdered by the murderer. This law is a game between the government and the murderer who uses one person's life as bait, and if the government loses, the result will be that one life will be killed. As a parent official, Lord Zheng should not only value the method of arresting the murderer, but also the lives of the people under your rule. If Shengjing Mansion encounters difficult and major cases in the future, if this method is used, it must be regarded as the best policy when it is forced to do so! ”

Zheng Guangqi's heart jumped when he saw Twilight's face, knowing that he had touched the mold of this living Hades again, but he didn't know what was wrong for a while, so he could only bite the bullet and say: "Naturally, it is the way to catch the murderer." ”

Hearing this, Twilight's face suddenly sank, and she asked, "Let me ask you, correlate the location of the crime, analyze the crime map, and narrow down and estimate the location of the next crime according to the suspect's behavior patterns, what do you see in this law?" ”

Zheng Guangqi nodded hurriedly, originally thinking that the investigation had been frustrated, but at this moment he became excited again, "The governor has this method of arresting the murderer, why didn't he say it earlier?" ”

"This is a series of murders, the murderer has a motive of indulgence, a typical erotic killer, addicted to abuse, flesh and blood or necrophilia, and the target is a virgin Qinglou woman. Therefore, the next thing to be done by Shengjing Mansion is to strictly order Chu Xiang Building, Lianchun Pavilion, Yihua Pavilion and Yuchun Building, and the sold chicks must be reported to the government. And what the government has to do is to know where people are going to be sent, and then compare these two maps to see if they will pass through the southeast alley on the way, and which one they will pass through, and then I don't need to say it, right? ”

Zheng Guangqi's eyes were straight, and Wu Jin's eyes were faintly shining, in addition to medical Taoism, he could even be very interested in other things.

After the drawing, Twilight spread out the two maps, and saw that the red alleys were clear at a glance, and there were really not a few left!

Just when he couldn't bear to look at it, Twilight Qing moved the map of the outer city to the side, dragged it over the map of the inner city, and circled and scribbled the forks in the same way, and the forks were bigger, "The east of the inner city is the imperial palace and the official residence, and it is impossible for the Qinglou woman to be sent here - excluded!" Most of the courtiers' mansions are in the north of the city, and most of the lewd pleasures are in the outer houses - exclude! In the south and east of the city, except for the outer houses, there are markets, while the streets in the inner city are different from the outer cities, most of them are streets, and there are not many alleys - excluding the streets, excluding the alleys in the southeast direction, and there are only a few left! ”

Zheng Guangqi was so happy to see her painting, as if there was blood flowing in his heart, and he couldn't bear to look at it again.

"The murderer committed the crime at the place where the murder and the body was dumped, and the process of committing the crime takes time, and it is impossible to choose the main street patrolled by the city guard. As a result, streets can be excluded and only alleys remain. Twilight dipped her pen in Danqing as she spoke, and drew a big blue cross on the main road and market in the painted red alley.

"To solve a murder case, it is necessary to know five locations - the place where the victim was last seen, the place of initial contact, the place of initial assault, the place of murder and the place where the body was found. In this series of cases, these five locations are concentrated in green buildings and alleys. The green building is a first-class green building, and the streets and alleys are southeast. There are only three first-class green buildings in the outer city, and there are this, this, and this ...... in the streets and alleys in the southeast."

Zheng Guangqi felt that he was going to commit a heart disease, and he couldn't regret it. This inner and outer city map is the Bing Cao Zhi Fang Shilang Chinese boss drawn, the old man has a long talent in drawing the map, once Feng aimed at the state and county patrol to draw the map of Daxing Kyushu, the map on the mountain peaks, rivers, city walls, garrison residences, towers and passes can be detailed, and the map in Shengjing City is drawn in three copies, one in the palace, one in the Bingcao, one in the Shengjing Mansion. Now that the old man is deceased, these maps are no longer difficult to redraw! He knew that the governor must have thought of the method of investigating the case when he wanted the map, so he found this one, but if he knew that he would scribble on the map, he must have found an ordinary one!

"Oh." Twilight Qing glanced at Zheng Guangqi, lowered his head, and put down his pen, "Those three Qinglou are here, here, and here......"

"This is painted by my own hand with the old staff of the soldier Cao, it is very rare!" Zheng Guangqi looked at the map of the ancient city that had been circled three times, and his face was distressed.

"Huh?" Twilight looked up.

"Governor!" Zheng Guangqi's voice rose suddenly.

Twilight doesn't expect the accuracy of these two maps, as long as she has the names of the streets and alleys, she can see where they are going. Immediately, she took the pen and painted, "Of these four cases, the first three were in the outer city, and the alley where the crime occurred was this, this, and this ......."

The two maps were spread out on the court table, and Twilight sat in the chair of Shengjing Mansion Yin, Wu Jin and Zheng Guang stood to her left and right, looking down at the map with her. Both maps are flat, showing that the inner and outer city gates are standing, and the streets and alleys are crisscrossed, and only the names of the four urban districts and streets and alleys in the south, east, and west are drawn on the map, and nothing else is seen, let alone the distance between the rulers and streets.

Although Zheng Guangqi didn't know what the map was for, he still hurriedly went to find it.

"Is there a map of the city in the palace?" Twilight suddenly asked, "Map of the inner and outer city markets." ”

“…… Yes? Zheng Guangqi was dumbfounded, feeling that these words really didn't seem to come from Twilight's mouth.

"You're right."

"Well, how is that good? You can't watch the murderer kill again, right? ”

"But I don't have time." Twilight spread her hands, she will return to the camp in the evening, and the training must not be delayed.

"How can this official be done?" Zheng Guangqi glared, this is too difficult for strong people, he tried to reason with Du Qing, "The pharmacy and the dart bureau are both places where people come and go, and the people who come and go are mixed, and it is very difficult to investigate, plus the Weiwei Mansion and the Yuan Judgment Mansion, the fast catch in the palace is that everyone is born with four legs, and it can't be checked in half a day!" Governor, it takes time for the lower officials! ”

"Possibly." Twilight nodded, but asked, "Can Master Zheng ensure that the ways through which these murderers obtained the powder will be investigated one by one within half a day?" ”

It's all possible!

"Governor, the Weiwei Mansion obviously has nothing to do with this case, and the lower officials think ...... Can I check Wo An Tong again? The murderer must be the one who can get the medicine powder, and Antang said that this medicine is only for the dart game, who knows if the shopkeeper is lying? Or maybe someone in the two dart games secretly sold the medicine? Or is there a medicine stolen from He'an Hall, the two dart bureaus, and the Weiwei Mansion? Or, is this medicine leaking from the Zhou court? ”

The only ones left are the housekeeper and the nurse, the housekeeper doesn't know martial arts, and the people in the nursing home who are good at light work are married, and they can all rule out suspicion.

The murderer is quite feather, and the old Weiwei only has one son, Liang Jun, and only one of the relatives of the Liang family is a military general.

The murderer did not raise it, and Liang Jun had a son under his knees, which obviously did not match the suspicion of the Weiwei Mansion.

Even putting aside his personal opinion and only extrapolating from the clues, Zheng Guangqi also felt that the Weiwei Mansion had nothing to do with the case.

With such a family style, it shouldn't be the Weiwei Mansion.

Zheng Guangqi served as the Yin of Shengjing Mansion for ten years, and he knew a lot about the character of the disciples in Beijing. Liang Jun has a good character, there are two preferences in his life, one is good martial arts, two is a good cook, Mrs. Liang's marriage has a restaurant, Liang Jun will invite three or five acquaintances to taste dishes and dance swords in his spare time, and there has never been a rumor that he lingered in Flower Street and Willow Lane. The old guard was injured in the palace change that year, and he resigned as soon as Liang Jun came out, and Liang Jun was very strict after he was appointed as the guard lieutenant, and it was strictly forbidden for the children of the clan to visit the Qinglou to raise plays.

Zheng Guangqi was not surprised by this result.

Zheng Guangqi came back before noon, and he checked the list of the children of Jingzhong who often went to the outer mansion of King Heng's mansion, and the result was that there were no people from the Weiwei Mansion, and there were no relatives of the Weiwei Mansion.
