The topographic map of Luyang County is twice as large as the world map of the wall calendar, but even so, it is still densely marked with the homes of nearly 400 people.

There are still six or seven hundred people in the county guard who have not been compared with their fingerprints.

If the comparison is finished, the information of more than 1,000 people is piled together, and it is not like a pile of ants?

Thankfully, she doesn't have a phobia of intensity.

The emotions of complaining were only fleeting, and Chen Chaoyan's mind was soon immersed in the topographic map.

Taking a pen and drawing a triangular symbol on the house in Zhou's Qiwan Lane, and then looking at the houses of the twenty-seven households working in the Silver Hook Cabinet Workshop within a radius of five miles with it as the center, Chen Chaoyan asked Xie Xuan, "Wuli Road, how long does it take to use light work?" ”

Xie Xuan took the pen in her hand, put aside the white jade fish dragon pen, and said, "Don't worry about this, Miss Chen, let's talk about your views first." ”

Chen Chaoyan asked inexplicably, "What do you think?" ”

Xie Xuan said: "Miss Chen went to Changliu Street and Jishanfang today, and compared so many fingerprints, what new views do you have on Zhou Zhongcai's case?" ”

"New opinion......" Chen Chaoyan glanced at the fingerprints of the county guard that had not yet been compared, and after sorting out his thoughts again, he said, "My brain is a little messy, I don't know where to start." ”

Xie Xuan said: "Then think of what to say." ”

"Let's sort out the progress of the investigation and fill in the gaps at the same time. I have already said that the basic classification of murder cases is for wealth, revenge or love, plus the power you add, there are four in total. Chen Chaoyan picked up the pen again, took out a piece of paper again, and wrote down 'wealth', 'hatred', 'love', and 'power' in turn, and then continued, "Today, we will talk about the direction of the investigation. ”

"The direction of the investigation of the case is divided into four steps: first, investigate the victim's situation; the second is to study the process of committing crimes; the third is to determine the motive for the killing; The fourth is to study the geographical environment of the crime scene. ”

After writing down the four steps on paper in turn, Chen Chaoyan said one by one: "We are currently investigating the victim's situation, and there is no result yet. ”

She drew a cross in the back.

"Studying the process of committing the crime, through on-site investigation and autopsy, it has been clear that there are two murderers, and the two of them assisted each other by striking the victim's ear root and concussing the medulla oblongata, and the other stabbing the victim's heart with a dagger at the moment when the medulla oblonga was shocked, and forged a suicide scene. But how the killer entered the scene needs to be further clarified. ”

She drew a half-tick.

"Determine the motive for the killing...... Although the prince said that it was for power and wealth, the investigation of the case paid attention to evidence, not unfounded words. So at present, this article is not yet implemented. ”

I also drew a half-tick.

"Studying the Geography of Crime Scenes......"

Chen Chaoyan nodded a little topographic map of Luyang County under his chin, "It's ongoing, but there is no half-point result yet." ”

So naturally draw a fork.

"The next thing is that if the relationship is implemented in Zhou Zhongcai's case, to put it simply, although Zhou Zhongcai's death method seems to be a procedure that has been set up a long time ago, why did this procedure not fall on other people, but on him? The power and wealth reflected in the motive for killing are what power and wealth are they for? ”

Chen Chaoyan looked at Xie Xuan.

Xie Xuan looked at the words she wrote.

Her words are more powerful than the poem "Yongxue", which penetrates the back of the paper.

It's like...... Compete with him.

Raising his eyes to look at her, looking at the hidden provocation in her eyes, Xie Xuan imperceptibly hooked the corners of his mouth and said, "I started practicing the words when I was four years old. ”

Seeing that she instantly turned into a relaxed look that she had already known, Xie Xuan suppressed his smile, tapped the bookcase twice, and motioned to her: "Go on." ”

"After grasping the relationship, you can determine the suspect according to the conditions ......of the crime" Halfway through the words, Chen Chaoyan suddenly paused, she raised her eyes to look at Xie Xuan, with annoyance, "You calculate me!" ”

Xie Xuan smiled and said gently, "How can I calculate you?" ”

Take advantage of the practice time and skip the question of what if! And she was fooled! Chen Chaoyan said embarrassedly: "After clarifying the direction of the investigation and grasping the relationship, you can screen the suspects according to the conditions of the crime." ”

"Through the IOU, we already know that the suspect has eight ......"

Yuejian looked at her annoyed appearance, and after smiling, she said happily: "Miss Chen always cheats me, and Gongzi has finally avenged me." ”

Chen Chaoyan was even more embarrassed, and after looking at her threateningly, he continued with a dull head: "But we don't know much about the information about the eight people at present, and this problem is back to the investigation plan mentioned earlier, so I won't talk about it for the time being." ”

"However," Chen Chaoyan picked up the IOU, looked at the fingerprints that had not yet corresponded to anyone, and said, "Shi Zhi's fingerprints cannot be extracted, but he still has to go to the Silver Hook Cabinet to take two copies of his handwriting for comparison, so as to rule out the possibility that it was imitated by others." ”

As soon as the words fell, Ling You staggered into the house, raised the two account books and a few IOUs in his hand and said, "Shi Zhi's handwriting is here!" ”

Chen Chaoyan took it, looked at it carefully, and put it together with the deed. Then, with the help of the light screen, the details are compared. The results of the comparison are determined to be the same. In other words, the deed of deed is indeed from Shi Zhi's hand.

Xie Xuan was no longer surprised that she had compared the results so quickly. Pushing aside the deed of deed and account book, he took out the paper she wrote, and after reading it carefully a few times, he lifted his eyes and looked at her carefully, "Did you follow the steps above to investigate?" ”

"If you have a direction, follow your direction." Chen Chaoyan said. She is engaged in technology, and she is not good at investigation, so she is not authoritarian.

Xie Xuanding looked at her a few times, then looked back at the content on the paper, and after a while, said, "Check according to the steps you wrote first, and then talk if you can't find the result." ”

Chen Chaoyan nodded, "It's okay." ”

Give the paper to Ling You and ask him to put it away. Then he took the topographic map of Luyang County and spread it in front of the two of them. Looking at the dense annotations on it, Xie Xuan turned back to the question she asked earlier: "Light skills are also divided into high and low, five miles of road, different light skills, and the time required is naturally different." ”

Chen Chaoyan asked casually: "How long does it take for the best light work?" ”

Xie Xuan replied: "The best light skill, when you run away, it is only between three or five breaths." ”

One breath is equal to about three seconds.

Three or five breaths is equal to about nine to fifteen seconds.

Between nine and fifteen seconds, five miles away......

Chen Chaoyan glanced at him incredulously, and then asked, "What about ordinary light skills?" ”

Xie Xuan replied calmly: "Ordinary light skills, when you run away, it is probably between sixty and eighty breaths." ”

One hundred and eighty seconds to two hundred and forty seconds, although it is also very fast, it does not seem unacceptable compared to the best light work. Chen Chaoyan continued to ask: "What about the poor light work?" ”

Xie Xuan's gaze withdrew from the topographic map and fell on her, "Then it depends on how bad it is." ”

Chen Chaoyan said: "It's generally bad." ”

Xie Xuan knocked his hand and tapped the book case twice, "Generally, when the light skill is poor, when you are escaping, it is almost a hundred breaths up." ”

Chen Chaoyan thought for a moment, pressed his eyebrows, and asked quietly: "The prince thinks that in this place in Luyang County, if killing Zhou Zhong was planned in advance, then what kind of people would the people or organizations behind it let kill him?" ”

"The lion elephant and the rabbit also use all their strength." Xie Xuan didn't think much about it, so he said, "Although Zhou Zhongcai is only an indecent Sicang in the county guard's mansion, he may be an extremely important person in the eyes of the people or organizations behind him. Although the world is big, there are no more than five people who have the best light skills. So, let's just count it as ordinary. ”

"Ordinary light work, that's between sixty and eighty breaths." Chen Chaoyan chattered while taking Zhou Zhongcai's house as the center and framing a radius of five miles, "After comparing the fingerprints of the county guard's mansion, I will first take five miles as the boundary to investigate and visit this piece of house." If there is no gain, expand the scope one by one. ”

Xie Xuan should be fine.

"In addition, the people who have close contacts between the county guard and the Silver Hook Cabinet Workshop must be investigated as soon as possible."

"And then there's ......"

Chen Chaoyan asked Xie Xuan, "When will the people who have close contacts with Zhou Zhongcai be found out?" ”

"Zhou Zhongcai is greedy for life and afraid of death, and he gets along well with the people in the county guard's mansion, and his contacts are almost the same." Xie Xuan said, "Almost all the people in the county have been to his house, but because of the crampedness of his family, not many of them have been there. ”

It's the same as Wang Da said.

Chen Chaoyan looked at the topographic map, and there were only twenty-seven people living within a five-mile radius centered on Zhou Zhongcai's house.

After roughly scanning the locations of the twenty-seven people, Chen Chaoyan took the fingerprints of all the people in the county guard's mansion, looked at Feng Shoudao's information on the previous page, and asked, "The sources of the hundreds of acres of fertile land that Zhou Zhongcai bought at the beginning of the year are all official fields?" ”

Xie Xuan nodded.

Chen Chaoyan looked up at him: "I've checked the accounts of the county guard's mansion, and it's confirmed?" ”

Xie Xuan said: "It's being investigated." ”

Chen Chaoyan nodded, tilting his head to look out.

It's already dark.

Another day passed.

And Zhou Zhongcai's case still has no eyebrows at all.

"There's no need to rush." Xie Xuan seemed to know what she was thinking, "Since the founding of the Great Wei Dynasty, although the record of solving the fastest case is also one day, the longest record is thirteen years. Zhou Zhongcai's case, judging from the clues obtained so far, is obviously not a small case. It's not surprising that it lasts for three or five months. ”

"I'm not in a hurry." Chen Chaoyan said.

Even in modern times with the rapid development of criminal investigation technology, it is not said that it must be broken in one or two days or two or three days.

She was just wondering if there would be another case tonight?

Retracting his gaze, Chen Chaoyan looked at the fingerprints of everyone in the county guard's mansion, and was about to pick up the last one for comparison, when Xie Xuan's folding fan pressed over, "I said that there is no need to worry." ”

Signaling Yuejian to pass the meal, Xie Xuan sat down in the pear wood chair on the side, looking at Chen Chaoyan, who stopped to drink tea, but his eyes still did not leave the fingerprints of everyone in the county guard's mansion, he asked intentionally: "Who is the old friend who wrote you poems?" ”

Chen Chaoyan raised his eyes, glanced at the servant, and then looked at him.

Xie Xuan leaned back in his chair leisurely and asked again, "Who is the old friend who wrote you the poem "Yongxue"?" ”
