Although Li Mi's drawings were only made casually, they were clear at a glance, and even those who had not been exposed to map analysis could understand Li Mi's intentions when they saw such a situation for the first time.

Because from this picture, they can completely see that although Zhang is not an assassin, but only an intelligence provider, they can still see her activity trajectory and scope from the map!

If you want to determine these widows and provide a list of the assassins of the Zhang family, the Zhang family must go out to investigate, and she is a family woman, it is impossible to leave early and return late, so time and even space are very tight.

In this way, from the chronological order and geographical location of the deceased's assassination, it can be seen that they are related to the Zhang family!

The intricate lines may seem confusing, but in general, they point to a wide range!

Li Mi's example is simple and straightforward, and Jian Dingyong and others finally understood.

If there is really a detailed map of Suzhou Prefecture, and then the location of the crimes committed by the Japanese invaders during this period is obtained from the Tuiguan Yamen, a large area can be demarcated like Li Mi.

And this area should be the range of activities of the Japanese Kou Meticulous Works, so the difficulty of the search is greatly reduced, and the workload is simply reduced by half!

To put it simply, this map analysis method takes the map as the research object, and studies the characteristics and related laws of spatial and temporal distribution through various quantitative and qualitative methods, which can be applied to all walks of life.

For example, if you are doing business, you can use map analysis to study the market, not to mention the use of maps in military and other aspects, and the study of maps in ancient military is even more important.

It's just that the knowledge of criminal investigation in ancient times was not too systematic, and it was also thanks to Song Ci, the originator of forensic medicine, who wrote a collection of grievances, that ancient criminal investigation was ahead of other countries and regions of the same era.

However, the map analysis method is applied to criminal investigation, even if someone has done it, but there has never been such a handy as Li Mi!

Li Mi is a criminal investigation professional, it can be said that he is standing on the shoulders of giants, what he says casually, what he paints and writes, in fact, is the essence of the criminal investigation industry for hundreds of thousands of years!

Some simple knowledge of criminal investigation in later generations, put in the context of ancient times, are all amazing innovations!

An official like Song Zhiwei, or a detective like Yuan Keli, may have also considered the relationship between geographical location and murder cases, and in the usual cases, they may unconsciously apply this aspect.

But they will never be like Li Mi, who is goal-oriented, organized, simple and powerful!

Jian Dingyong is the number one leader of the county government, and the cases are also handled by him, and he has also experienced a lot of crime investigations, but after all, his vision will be limited, and when he sees Li Mi's hand, how can he describe it with the word shock!

As for Master Qian and Dian Shi, they felt again and again that they had underestimated Li Mi's little catcher, but they were refreshed by Li Mi again and again, and at this time, they looked at Li Mi as if they had seen a monster descending from the sky!

"It's... That's what you came up with? Jian Dingyong took a long time before he spoke, and his face still couldn't hide his disbelief.

If you can learn this method, it will be much easier to search for suspects and other tasks in the future!

Of course, don't look at Li Mi's casual scribbles, but studying the rules is not a simple matter, in their opinion, it is full of all kinds of calculations and co-ordination, which is not something that ordinary people can learn!

Throughout ancient history, there is usually one sentence used to describe cattle people, that is, to know astronomy and geography.

In ancient times, science and technology were backward, the means and tools of observation were very low-level, and human beings could only observe the world with the naked eye, the sky and the earth, which were the greatest, most mysterious and most desirable places.

Their eyesight is limited, so they can't see the higher sky, and can only measure the earth with their feet, so anyone who has studied astronomy and geography is definitely an unborn cow!

And it's okay not to study astronomy and geography casually, because the stars in the sky correspond to the princes and generals on the earth, and only Qin Tianjian can study them.

This map analysis method seems simple, but it is only for Li Mi personally, in the eyes of Jian Dingyong and others, Li Mi, who can study geography, is no longer such a simple character as ordinary Xiaochai!

Li Mi listed this method as the next policy, and other methods did not work, or Jian Dingyong and others did not dare to do it, so they had no choice but to retreat, so they used the map analysis method.

But in the eyes of Jian Dingyong and others, this map analysis method is the really lofty thing, and it is the thing that really shocks their hearts!

Jian Dingyong looked at Li Mi at this time, thinking of Li Mi's performance during this time, but he became more and more incomprehensible.

It is said that a wise man like Li Mi should be arrogant and disdainful of stepping into officialdom, but Li Mi is willing to be a small catcher.

You must know that catching fast is not a serious background, after being a fast catcher, it is almost impossible to be an official, even if you become the chief catcher of the road, you are not an official after all, but anyone who has some ability, who is willing to do this?

At first, he didn't think about it, Li Mi may just use the act of catching fast as a springboard, the real purpose is to make a difference in the county government, and being willing to catch fast is just to get his Jian Dingyong's recognition and promotion.

Li Mi is not a wild man in the mountain village, at this time it seems that he is even more extraordinary, his resourcefulness and character are excellent, even if he did not participate in the imperial examination, if he wants to make a difference in the officialdom, it is not difficult, such as a staff strategist like Master Qian, it is a good way.

In fact, it is no wonder that Jian Dingyong thinks like this, although catching fast is not on the table, but in Li Mi's opinion, catching fast is the easiest for him to get, and it is also the closest to his old job, as for the future, although he has some considerations, but this is a start.

People say that everything is difficult at the beginning, but after all, it must begin, if there is no beginning, what is the future?

Li Mi's performance finally completely impressed Jian Dingyong, but at the same time, it also attracted the suspicion of the other party, which was also expected.

However, the results achieved by Li Mi are too great, Jian Dingyong will not refuse Li Mi's proposal at all, if he can really dig out all the Japanese who are lurking in Suzhou Mansion through the map analysis method as Li Mi envisioned, then the merit and political achievements will be immeasurable!

Thinking of this, Jian Dingyong no longer hesitated, although it was not yet dawn, he was also sleepy, and instructed Master Qian.

"Master Lao told me to go down and prepare, I want to go with Li Mi to see the prefect."

When Master Qian heard this, he couldn't help frowning, and said to Jian Dingyong: "The county honor... This matter can be big or small, if it can really work, everyone will be happy, but if there is a mistake, the responsibility will fall on the head of the adult..."

What Master Qian said is not unreasonable, the city defense map is an extremely important thing, what is really going to happen, it involves the entire Suzhou Mansion, even if Li Mi is cut down, it will not help, but Jian Dingyong's career will be dusty and stained, and it will be difficult to say in the future.

As a staff member, it is understandable to weigh the pros and cons for Dong Weng, but it is a little inappropriate to put it here.

Li Mi is a county celebrity these days, although Jian Dingyong is knocking and beating on the surface, he actually accepts Li Mi's advice in many things, and in essence, he is obedient to Li Mi.

As a result, Master Qian has fallen out of favor, and now he is proposing this stubble, which is inevitably suspicious.

Jian Dingyong was really a little displeased after hearing this, and said to Master Qian: "Just care about the order, this kind of noise is so bad, the county will take care of it!" ”

Master Qian frowned, and he didn't dare to say much, but he never showed hostility towards Li Mi, nor did he look at Li Mi with cold eyes, so he obediently walked out of the study and arranged for himself.

Li Mi saw the back of Master Qian, and he also had some admiration in his heart, although he had no intention of officialdom and just wanted to solve the case, but a person like Master Qian had such a city government, and the position of Master Qian was really condescending.

Jian Dingyong obviously didn't take this to heart, Xingtou still stayed on the map analysis method, and asked Li Mi a lot of questions.

According to the geographical analysis, Li Mi pointed out several places where murders may occur, all of which have the same characteristics and are also within the scope of Zhang's intelligence.

Jian Dingyong immediately asked the canon to take the file, and after checking it, he found two unsolved cases, which were within the range of Li Mi's point, and he was even more convinced of this map analysis method.

When the group arrived at the mansion, it was still not dawn, so Jian Dingyong took Li Mi to the torture hall first.

Song Zhiwei is a magistrate of the four prefectures, in charge of prisons, praising the code, arresting robbers, and stabilizing the locality.

The Torture Hall is a place dedicated to dealing with prisons, which is more powerful than the county government, and the murderous atmosphere is very strong.

Although Song Zhiwei controls real power and is a prefecture-level official, after all, he is almost equal to Jian Dingyong in terms of official rank, so he doesn't dare to be too lazy.

Although Jian Dingyong also investigates cases, he is a county official in the end, and he grasps all kinds of chores, so in comparison, Song Zhiwei is more interested in Li Mi, who focuses on solving cases.

Especially after knowing that Li Mi had a relationship with Yuan Keli, he asked people to investigate Li Mi's details, and knew that Yuan Keli actually recommended Li Mi to Xiang Mu, and Xiang Mu was also very affectionate to Li Mi, which made Song Zhiwei dare not underestimate Li Mi!

This is one of the advantages of being a detective, through investigation, you can know the inside story better than others, and you can avoid many unnecessary misunderstandings and troubles.

As soon as Jian Dingyong saw Song Zhiwei's attitude, he knew that he was on the right path by bringing Li Mi, and after sitting for a while, he told him what he meant.

Song Zhiwei is a pusher, and he is much more professional than Jian Dingyong in criminal investigation, and he has also used methods such as geographical analysis, and he also has such a concept in his heart, so it is not difficult to understand.

What really surprised him was that Li Mi was able to organize these detective skills so systematically, and he could also tell the principle!

As a push official, it is also his duty to prevent the Japanese invaders, although the city defense map is indeed important, but the stakes are very important, and Song Zhiwei did not dare to delay, even if he led Jian Dingyong and Li Mi, to find the prefect of Suzhou.
