Daqing Criminal Division

Early the next morning, the members of the temporary investigation team of Jiangning Mansion got together again.

Because yesterday's case had progressed to the point of how much the criminal had marked the stolen famous painting in advance, today they mainly gathered together to discuss how to find the specific location where the gang itself was hiding.

As we all know, Jiangning Mansion has a very large meter range.

The north-south runs through the Grand Canal, and the floating population of ships, carriages, and the city gates and ports every day is very dense. Even if people are sent to lock the gates now, it is impossible to fully guarantee that while arresting and dismantling suspicious explosives, they will not be caught. Start by beating the grass and scaring the snake.

But in fact, the opponent's group of "Southern Anhui people" whose faces are hidden in the dark.

To cooperate with each other to complete such a well-deployed bomb raid plan targeting the entire government office, it is necessary to choose the best hiding place.

One is a city-wide search, and the other is a city-wide hiding.

Therefore, in the case of the premeditated attack on Jiangning this time, it is difficult to say whether there will be a winner or loser in the game between the government and the criminals.

Right now, all the people related to this case are sitting together in different postures in the inner hall, waiting for Sima Zhun to come out and they will hold a small meeting.

Among them are the three people from the Songyang County Yamen who assisted them in handling the case this time.

There are also several local police officers from the Yamen of Jiangning Prefecture itself. It was also introduced by them and Zha Keshan just now. It is known that the three are named Sun, Chen and Wang respectively.

The three local police officers who were recruited by Sima Zhun to take charge of this case were extremely burly and capable.

Most of them used to be in charge of major and important cases, and each has more than ten years of experience in handling cases.

This time, the main duty is to lead the subordinates to dismantle all kinds of dangerous explosives scattered in Jiangning, and to search Jiangning.

Hanging in front of the hall is a huge map spanning Jiangning, with countless red circles connecting the ports, wharves, Hongqiao and inns that the suspects passed by, so that all suspicious locations can be clearly marked.

Early in the morning, Duan Xiao and Fuchaerzi were the first to come.

Both of them barely slept yesterday.

But one was holding his head, and the other was doing other things with his arms folded, but his spirit seemed to be better than usual, and he didn't seem to be affected in the slightest.

In comparison, the other officials working in the Jiangning Yamen who are used to their usual work and rest are in a more miserable situation. Not only are they tired until the middle of the night, but they have to get up early in the morning to continue arresting the suspects.

"morning."

When he saw Duan Xiao appearing, he seemed to be the same as usual, and Fuchaerzi, who was resting on his arm, also beckoned to him.

"morning."

He didn't say anything else about it, and usually he might not respond to this sentence, but today when Duan Xiao sat down next to him, he greeted him uncharacteristically.

Such a normal thing is a bit abnormal for these two people.

When Zakshan came over with them in the morning, he wondered why the relationship between these two guys suddenly seemed to improve a lot today, and there was an inexplicable atmosphere.

But it seems that they don't intend to explain the reason, so it's not easy for others to ask.

After a while, Sima Zhunren also came out.

Not only that, but last night he didn't sleep all night, and he brought the most detailed plan that the government can give today.

It is also to redistribute these documents to everyone in front of them.

Knowing that the current situation is urgent and there is no time to lose a second, the Chief of Police of the Jiangning Mansion sat in front of the table with his fingers crossed, frowning and said solemnly,

"Everyone must have slept poorly last night like me... To be honest, this case is of a special nature, not only involving Jiangning Mansion itself, but also colleagues from Songyang who cooperated with us in the investigation, so yesterday I reported to At the Riyue Sheng ticket office, I asked in detail about their ticket issuance time this time."

"According to the usual practice, the issue date of the bank note of the Sun Moon Sheng Bank is on the [-]th of this month. It is impossible for outsiders to know the place and time involved."

"However, while the criminal suspect Wang Tianxiao was pretending to be Zhang Santong, he had been pretending to be acquaintances at the Meixiang Inn to inquire about Xiaogong and other excuses, and had collected many ticketing dates of the Sun Moon Sheng Ticket Number from several old shopkeepers among the ticket numbers. These scattered information are very likely to be the main source of information for this group of criminals to sneak into Jiangning Mansion and formulate the plan to hijack the official bank."

"Previously, this group of gangsters used the name of the melon seller in southern Anhui to set up fire bombs in Jiangning Mansion one after another, probably for the purpose of this official money."

"Now, we still have a full fifteen hours to try to dismantle these dangerous items in the city, catch this group of criminals, and stop their actions before they cause greater commotion and danger. Everyone, join me in trying to protect Jiangning's safety, so for the time being, we will name this arrest plan, Suspect A, Arrest Plan."

"And I, Fucha and Duan Xiao will jointly command this operation."

After the last sentence, Fuchaerzi and Duan Xiao paused twice.

The two raised their heads to look at Sima Zhun in front of them with a little surprise, but saw that the chief of the Jiangning police did not back away and just looked at them calmly.

Suspect A arrest plan.

This seems to be Sima Zhun's preliminary plan for this big Jiangning Mansion case.

But when they heard the latter sentence, the other police officers of Jiangning Mansion obviously didn't expect that Sima Zhun would hand over the command power to these two outsiders so easily.

In this regard, Fucharzi, whose expression was obviously paused because of this sentence, seemed a little surprised, and only raised his hand to say something before others raised objections.

"Well, Sima, I think I have to say something, I am not an official at all, and I have never done this before. Why don't Duan Xiao directly—"

What Fucharzi meant was obviously to say that he, an outsider who had nothing to do with the government, was not suitable for this kind of thing.

After all, what he said was not lying, he had indeed not done 'this kind of thing' for a long, long time, but the refusal words he had already said were used by Sima Zhun who raised one hand The conversation was interrupted.

"No, Fucha, Duan Xiao, I understand the concerns of the two of you at the moment."

"But this time it's not just about the government and the policemen, but about the safety of the entire Jiangning Mansion. You two are very suitable, and I'm not an unreasonable person. If I'm in charge of everything, I'll order you later. You didn’t have enough space to do your best and missed the best time to save people, which is why I can’t absolve myself of the blame.”

"Besides, you are not outsiders, nor is it the first time you have done something like this. I think it would be perfect for the two of you to participate in this plan."

What Sima Zhun said was reasonable.

He knew in his heart that there is no one in the huge Jiangning mansion who is more capable of taking on this important task than the two in front of him.

Although the two of them are not official servants, there are many things that can't be seen through themselves, just like the current crisis, he needs the two of them to save the safety of Jiangning Mansion.

Since then, Fuchaerzi and Duan Xiao have not refused again.

So after that, Sima Zhunzhi divided the staff at hand into two groups in detail.

That is to say, some of them privately removed the nine known 'Watermelons' in the city without raising eyebrows, and the other part focused on searching for the hiding places of the remaining 'Suspect A 039' and the possible locations of the other three 'Watermelons'.

And as the two people who seem to be most responsible in this case so far.

Naturally, Fucha Erji and Duan Xiao had no choice but to do their part, which is why Sima Zhun also had a serious expression on his face when the two main command powers were handed over to them.

In this way, the deployment plan depends on two people.

So after that, Duan Xiao, as one of the commanders personally appointed by Sima Zhun, got up and explained to everyone his views on the investigation of the case.

Now, except for the three houses that have been demolished, the positions of the twelve modified "watermelons" in the most central "Qingyuan Riverside Scene at Qingming Festival" have been basically found out.

At first, everyone didn't understand the purpose of these symbols.

But Duan Ou, who went back last night and spent a whole night thinking about the usage of this symbol, also used the location ([-], [-]) as the origin, and locked the positions of these 'watermelons' with the same two-two number mark symbol, and held it in his hand He tapped his pen to everyone in front of him.

"Everyone can take a look, this is the way these 'Southern Anhui people' used to mark the map. It is called 'coordinates' in ancient books."

"As early as the Wei and Jin Dynasties, a boatman named Pei Xiu used the grid mapping method to determine the nautical orientation and gave birth to the prototype of this azimuth orientation."

"Divide the location of the area with 'coordinates', and then mark all the buildings in Jinling City with numbers according to the north-south direction, instead of deliberately remembering the specific location of any building, you only need to memorize the numbers."

"Right now, the markers on this map mainly include the entrances of the four city gates (200, [-]-[-]), the Sun Moon Sheng Ticket Number, and the point [-] meters away from the intersection of the street (Si Lu , Baiqi), two tea houses along the street (Qilu, Erwu) (Jiuwu, Shisan), Yushi adults Zuo Shen (Lu Ba, Baijiu), Jinling prefect Su Qizhan (Yi Er, Si Lu) , Assistant Superintendent Mingpeng (Bai Lu, Qi Wu).

"These nine points are most likely where nine of the twelve bombs are located."

"However, because three of the houses have been demolished, it is difficult to find the exact coordinates. Therefore, if we want to find out where the three 'watermelons' are, we may have to catch this group of people and interrogate them carefully."

"But now there is still a big problem. There may be other hostages in the hands of this group. This is what we need to discuss in detail."

What Duan Xiao said in his mouth is indeed a problem that the entire Jiangning government needs to deal with.

Before that, he was a person who had personally experienced a similar major case, namely the pig man case.

Therefore, I am afraid that there is no one present who understands better than him that the most severe test of this type of bombing is actually how to ensure the safety of the nearby people once there is a riot itself.

But in the past four or five years, the city defense of Jinling has changed.

They didn't know where the three 'watermelons' whose details had been lost for the time being, and whether there were any hostages in this group's hands were all issues they needed to consider.

The same is true, and the police officers who listened to these words were also pale.

But at this moment, Fucharzi, who had been staring up at the densely packed 'coordinates' on these maps, made a point of his own.

"Perhaps, we can use this map marked with building coordinates to reversely lock the location of this group of 'Southern Anhui people' themselves?"

"How do you want to reverse lock their position?"

Duan Xiao also took a look at this person when he heard the words.

"origin."

Rarely stood up very seriously, and continued what he said just now, knowing that he must understand what he meant, Fucharji only looked at Duan Ou, pointed to one of the points, and said.

"If this is really a map marked with coordinates, where is the central origin that should have existed on this altered map of Qingming Shanghe?"

"..."

When Fucharzi said this, others still didn't understand what it meant.

Duan Xiao already understood what he wanted to express.

"You mean the central origin?"

Following his train of thought, Duan Xiao, who was standing under the map with his arms folded, asked him aloud.

"Yes, that's what I meant."

Fucharzi, who was playing charades with him, also said something.

The two of them went back and forth, and the others didn't understand even more.

But in the eyes of the two, all the previous clues about this picture of Qingming Riverside are indeed connected in one go.

At the moment, the two looked at the city defense map next to them for comparison, but after seeing the various coordinate marks on it, the Qingming Shanghe map marked by "Wannan people" did not have the origin.

origin.

In layman's terms, it is where (zero, zero) is on the map.

According to the usual coordinate map, this place should exist. After all, it is precisely because of the origin that other coordinates can be divided. Therefore, Sima Zhun, who wanted to understand, suddenly followed up and said,

"So, so, what you two mean is that the 'origin' is likely to be the temporary hiding place of those 'Southern Anhui people'?"

"Correct."

The two turned their heads at the same time and said in unison.

Now other people also understand what this so-called 'origin' means.

It turns out that the only place on the marked "Qingming Shanghe Tu" is the origin. If there is no origin (zero, zero) on a map, then the locations of other bomb installation points are also different. existing.

And the group of criminals themselves wanted to set up the location for the explosion of dangerous goods, and the most likely origin they chose was their own hiding place.

Thinking about it this way, the temporary arrest plan this time is also clear at a glance.

At the moment, the Jiangning mansion hastily sent people to spread out the two maps on the wall, and gave Fucha Erji and Duan Xiao enough time to use the existing 'coordinates' to determine the map hidden in Jiangning mansion. The center of the origin is located.

But just for a moment, under the gaze of everyone who was so nervous that no one in the inner hall dared to speak.

The two, who had been entangled in this case for a long time by various clues, only divided the work and marked several original coordinates on the map, and re-drawn the coordinate axes.

One of them draws the horizontal axis and the other draws the vertical axis.

Because the two intersecting coordinates are destined to meet eventually, you only need to draw all the vertical lines with the same abscissa and ordinate, and then translate to draw a definite conclusion.

Waiting to see the two new coordinate axes pass through the inns, wharves, rivers, and other buildings distributed on the portrait, Fucharzi who is gathering from both ends of the table to this end. Draw the most central point at the same time as Duan Owl.

It was also at this moment that the location of the origin, which was found by the two together, was suddenly exposed.

Everyone gathered together and looked at the map that had been drawn with all kinds of coordinates, but saw that the most central location unexpectedly matched a place in Jiangning Mansion that they had never thought of before.

"This place...could it be the Wengcheng Village under the Jubao Gate!"

The exclamation in the mouth of a policeman next to him made Sima Zhun and the others instantly refreshed.

Because the only urn in Jiangning Mansion is located under the Jubao Gate of Jiangning Mansion, it is one of the thirteen gates and walls of the Ming City Wall.

It has been one of the important trading ports since ancient times.

It is backed by the main city and the port, and is very close to the most important ticket exit of the Riyue Sheng Ticket Company. In addition, there have been a large number of migrants in the past two years, and most of them live here. There are inns, small stalls, large and small houses, and the large Wengcheng. The village has the largest and densest urban village buildings in Jiangningfu.

Once a group of outsiders gathered here and hid there secretly under the surveillance of the government, checking the news in the city every day, no one could easily find out where they were.

After thinking about it that way, the people in the yamen didn't waste any time.

After realizing it, Sima Zhun shilled one of the three most effective arresters under his command. After putting on a disguise, he hurriedly took someone to the Wengcheng to find some people to ask quietly, and asked if there were any group of Wannan prostitutes in the past two days. Melon people have been here.

At the same time, Fucha Erji and Duan Xiao also combined the previous autopsy results on Wang Tianxiao and gave some other key points to search for this group of people.

First, it is likely that this group of people did not stay at the inn during this period, but rented a private house near Wengcheng by themselves.

Because Liu Cen is still being kidnapped by them, and using fire nitrate to make side-mounted slow guns requires a sufficient experimental area, and there is a certain possibility of small self-detonation, so the inn where people come and go is not the best place for them to hide. Place.

Second, it is very likely that this group of people will often come out by different people in turn to buy some meals nearby and go back to eat at one time.

Because they are a gang to commit crimes, it is impossible for a group of people to be exposed to the light all the time and attract the attention of most people, so every day they must have different people who buy several meals at once to take home.

But because they had one more hostage, Liu Cen.

Then every time this group of people must buy an extra copy, so based on this, it can be checked whether there is such a group of people in the nearby stalls or restaurants.

The third is that when Wang Tianxiao killed his accomplice earlier, the group used a lot of frozen watermelons to freeze the body to avoid being discovered by others.

Making ice with fire nitrate is certainly a good way to quickly freeze, but at the same time, it also requires a lot of water to complete this process.

It is impossible for a group of people to temporarily go to another place to fetch water and make ice to kill someone just because they want to kill an accomplice, so the place they rented temporarily is either close to the Qinhuai River, or has a well, so that they can kill Wang Tianxiao and freeze him that night of this process.

In this way, the scope of where the "Southern Anhui people" committed crimes is located in Wengcheng is also suddenly narrowed.

seventeenth.

Jiangning Mansion

A number of officials disguised in disguise went to the Jubaomen area, knocked on the door one by one and questioned several people who had rented their houses to outsiders for nearly a month.

Among them, [-] households provided information about foreign businessmen staying in Jiangning for a short period of time.

Sima Zhun and Duan Xiao based on the information of these migrants and ruled out normal businessmen who lived with their families and rented out alone, and those who did not have the possibility of committing crimes, leaving three suspicious targets in the end.

These three are distributed in the core area of ​​Jubaomen Urn City.

They all directly rented an entire private house from a local family in Jiangning with money.

It is said that they are all under the banner of foreign business, there are several men accompanying them, and all of them are young and strong, and they came here with a lot of luggage.

The government secretly sent people to monitor the three suspects within their range of activities.

And according to what I said before, I inquired about the daily activities of these three groups in major restaurants and the like, and finally got it from a restaurant called Huaiyang Xiaoguan near one of them a day later. Such an important clue.

This crucial clue was originally provided by a waiter in this small restaurant.

The shop waiter is a local.

Every day, under their small restaurant, they receive some diners and pack some meals for the shopkeeper.

Because their shop is the only one in the vicinity and opened a small window early in the morning to make soy milk fritters, buns and pot stickers for the nearby porters, and the taste of the mosque is still made, so diners who come and go come here every day to pack a few copies take away.

When it comes to who is there every day, his eyes will definitely not mistake people, and it is the same. When asked, the waiter in the shop immediately reacted and said another sentence.

"Then a group of outsiders who live in the south and rent the courtyard of Old Cui's house have really come to your place to buy sesame seed cakes every day for a month."

The Jiangning mansion secretly dressed up as an official asked quietly behind the small window of the restaurant.

"Yes, yes, it's absolutely true! In fact, I also thought it was very strange before. In the past half a month, I have seen four people take turns to buy our store's potstickers and sesame seeds."

"Each of these four people doesn't like to talk to people, they just leave after shopping, and the meals they buy are similar every time."

"But every time this group of people want five servings of soy milk, I thought at the time that the number of buns and sesame cakes can vary, but this soy milk will definitely not be bought. I am afraid that there is another person in the family hiding it all the time. never came out..."

"..."

As soon as these words came out, it became clear at a glance which of the three suspects in the government was the real hiding place of the "Southern Anhui people".

nineteenth.

Under the command of Sima Zhun once again according to the deployment on the ground, a plan to round up this group of criminal suspects in Jiangning Mansion was launched.

That day, Fucha Erji, Zha Keshan, and Duan Xiao also followed.

When approaching this Wengcheng residential village.

A black dog owned by one of the officials in the yamen had already followed the scent, walked all the way into the alley, and then turned around and barked at them.

Bending down to touch the dog, Fucha Erji waved silently to the little yamen servant who came over to take the dog away, not to startle the snake, and then he and Duan Xiao scattered on the left and right by the door and slowly approached the place located in the alley. The entrance of the small house in the depths.

I saw a few watermelon rinds that had rotted for several days discarded at the door, and a few particularly eye-catching watermelon seeds scattered on the steps.

There are also some flies flying above.

It was instantly clear in my heart that I was afraid that the two people who had found the right place were next to the door, and looked at each other expressionlessly.

Duan Xiao, who looked coldly through the crack of the door, raised his hand and knocked on the door tentatively with a 'dong dong'.

There was an odd silence at first.

Then, under the watchful eyes of all the policemen with knives who had surrounded the place at the door, they only heard the sound of footsteps coming from the door, and then a man with a Huaiyang accent was very vigilant answered aloud,

"...Who is it, who are you looking for?"

The author has something to say: Alright, let’s start catching people~

Today shouldn’t be too late, haha, thanks to the little angels who voted for me or irrigated the nutrient solution for me~

Thanks to the little angel who irrigated [nutrient solution]:
