I am the best in the world with the crime solving system

Xie Xuan didn't know what she was thinking, so he found a comfortable position leaning against the pillow, and put his legs on the low stool.When Shi Shu and Wen Mo came forward to beat his legs and squeeze his shoulders, he asked with great interest: "What is the chain of evidence?"

Knowing that he was just asking casually, and maybe he didn't mean it at all, but with the idea that correcting his ideas must start from the small things, Chen Chaoyan still replied seriously: "The chain of evidence refers to the collected witnesses, physical evidence or evidence. Confessions and other evidence can corroborate each other and can completely prove the evidence system of his criminal process. Taking Ma Huai as an example, although the physical and personal evidence found so far proves that he is the murderer of Zhou Zhongcai, Shi Zhi and Li Er, but It is an objective fact that he does not know Li Er."

"Take Ma Huai as an example..." Xie Xuan read it in a low voice, and said calmly, "Ma Huai said he didn't know Li Er, but he said, but there is no evidence to prove that what he said is true. In other words Said that, except for not knowing Li Er, all the physical evidence and personal evidence found so far can be mutually confirmed."

Chen Chaoyan: ...

It was a fact, and she couldn't refute it.

Xie Xuan looked at the dumb look she wanted to say but couldn't say, and smiled silently with the corners of his lips curled up, "Miss Chen actually knows, too. Based on the current evidence, it is completely enough to convict Ma Huai."

That's true, but...Chen Chaoyan fought hard: "Yes, in terms of the evidence found, Ma Huai can indeed be convicted. But has the prince ever thought about why Wang Da and his like would cover up Ma Huai if it was really Ma Huai?" he?"

Xie Xuan slowly reminded: "Did Miss Chen forget again that Ma Huai committed a crime in Zhangwa Village two years ago. If his uncle and uncle hadn't confessed him to protect themselves in this case, Once Zhou Zhongcai died, it can be said that the clouds disappeared. Similarly, if he had committed a case similar to Zhou Zhongcai's before, because his own safety was not involved, it is normal for no one to come forward and confess."

After a pause, he said again: "There are two murderers, but it doesn't mean that these two must be in the Sheriff's Mansion."

This is indeed possible, after Chen Chaoyan nodded in agreement, he wanted to say how to deal with it.But at the moment when the words were about to come out, after meeting his teasing eyes, he suddenly understood the reason for his aggressiveness!

After closing her eyes slightly, and suppressing all the overwhelming emotions, Chen Chaoyan turned her head to look at the scenery outside.

Yuejian asked the waiter in bewilderment: "What's wrong with Ms. Chen?"

The servant took a look at Chen Chaoyan, and said in a low voice: "Miss Chen is so obsessed with the conclusion that Ma Huai is not the murderer, that she is confused."

Yes, she was upset.

The purpose of her continuing to investigate the case is to catch the real murderer, not to reverse the case for Ma Huai.Therefore, the correct approach should be to integrate all the evidence and sort out the clues like when we first investigated the case, and then clarify the direction of the investigation, and then conduct investigations.Instead of grabbing a guess and overturning the existing evidence like now.

It was precisely because Xie Xuan saw that she was going in the wrong direction that he would use her tricks to refute her guess and make her repent when she had nowhere to go.

"Are you depressed?" Seeing that she hadn't spoken for a long time, Xie Xuan teased.

"No." Chen Chaoyan turned her head, her gaze was calm and sincere, "I was just thinking about how to thank my lord."

"Have you thought about it?" Xie Xuan asked lazily.

Chen Chaoyan twitched the corners of her lips, "Wang Ye, help me refer?"

Xie Xuan chuckled, "Let's hear it."

After thinking for a moment, Chen Chaoyan said slowly: "All the eight people with fingerprints on the deed may be the murderers. There is no doubt about it. Among the eight people, Mr. Feng and Zhao Wuwei stayed in the county the night Zhou Zhongcai was killed. Guarding the mansion, there are yamen guards to testify, and Mr. Feng does not know martial arts, and Zhao Wuwei has been following Mr. Feng since he became an official. More importantly, they came to Luyang County only in the first half of the year. The sheriff and county magistrate of the Wei Dynasty are replaced every four years. The decision of where they will be replaced next time lies with the Ministry of Officials. That is to say, Feng The possibility that your lord and Zhao Wuwei are one of the masterminds behind Zhou Zhongcai's power-for-money is very slim."

"Since it's so insignificant, we can temporarily rule out their suspicion."

Xie Xuan nodded, "Continue."

"Uncle Sun has been in the Sheriff's Mansion for two years. Before entering the Sheriff's Mansion, he worked in the Jianing County Government. There is no way to lie about this, so his background is simple and clear. In addition, from his own conditions, family conditions and personnel flow Judging from the circumstances, the possibility of him being the murderer is also very slim." Chen Chaoyan said.

Xie Xuan nodded again.

"Ma Huai..." Chen Chaoyan was silent for a moment before saying, "The family runs a pharmacy, so it can be said that they are familiar with the human body. It is the judicial history of the county magistrate, Cao Xia, and it can also be called anti-reconnaissance ability. In addition, he has participated in the massacre of the Bao family and knows martial arts. Coupled with the various evidences that have been investigated, he is undoubtedly the most likely murderer."

"As for whether he has committed a case similar to Zhou Zhongcai's in the past, my suggestion is that after returning to Luyang County, we should focus on investigating the reason why he entered the county guard's mansion, such as power or money."

Appreciation flashed across Xie Xuan's eyes, and the composed and calm Chen Chaoyan returned.

"In addition," Xie Xuan restrained his emotions when she looked over, and added slightly, "you can also start to investigate whether there is a possibility of stealing people's fingerprints without their knowledge."

Chen Chaoyan's eyes lit up for a moment, but then he shook his head and said, "It's not difficult to steal his fingerprints, but what is the reason for stealing his fingerprints? I have never told anyone about the fact that I know how to use fingerprints to solve crimes."

Even if Ma Huai was apprehended, it would be based on those secret letters as evidence, not the fingerprints on the secret letters.

"Muyuantang and Zhaixing Pavilion have the murderer's eyeliner?" Yuejian asked.

"Impossible." The servant said, "Lingquan has secretly checked the identities of the maidservants serving in Muyuan Hall and Jiexing Pavilion. In addition, their daily words and deeds are also under surveillance."

Yue Jian said: "Then what's going on?"

Chen Chaoyan frowned and looked at Xie Xuan.

Xie Xuandao: "Whether the murderer of Zhou Zhongcai is an individual or an organization, it is not easy to see that there are not many other clues except fingerprints. And we have been collecting fingerprints, even if the murderer doesn't know what there is. However, there are precedents for solving crimes in the form of bloodstains, which does not prevent him from making correct guesses."

The servant glanced at Chen Chaoyan calmly, "According to the young master's analysis, those few secret letters are the murderer's probing work?"

Xie Xuan didn't answer, but looked at Chen Chaoyan, and motioned her to tell her how to collect Ma Huai's fingerprints without alarming him.

Chen Chaoyan said: "After excluding Master Feng, Zhao Wuwei, and Uncle Sun, the remaining five suspects, Qian Wen, Wang Da, Song Yanzhong, and Shen Jimin, are all Ma Huai's superiors. If you want to extract his fingerprints, feel free to If you find a reason, you can easily achieve your goal.”

At this point, Chen Chaoyan suddenly said after a pause: "Those three pieces of paper for the secret letter..."

At the same moment, Xie Xuan also said this sentence.

The two looked at each other and saw smiles in each other's eyes.

Obviously, at the same moment, they all thought of the case of the middle-aged man who lost money in Beilu County.The key to solving the case was the middle-aged man's cloth.In the same way, the Great Wei corresponds roughly to the part of the Tang Dynasty in the historical torrent that Chen Chaoyan knows.The paper in this part is still a luxury.Therefore, as long as we start with paper, we can further lock in the murderer.

The moment the two mentioned paper, Shi Shu and Wen Mo also thought of the case of the middle-aged man who lost money at the same time.There are few words in words, and the one who speaks is still Shi Shu, "Those three secret letters are made of jute paper that Shu County paid tribute to."

Knowing that Chen Chaoyan didn't understand the affairs of the court, the secretary explained to her specifically: "The major yamen in the Great Wei Dynasty all used white and jute paper that was tributed by the Shu County. The white hemp paper is used for the preservation or It is the official paper issued by the ministries, and the jute paper is the daily paper used by the yamen. But whether it is white linen paper or jute paper, there is a quota. After returning to Luyang County, let Sicang Cao check it out. Check the quota of each cao, and then check the public figures in each cao, then it will be clear at a glance where the white hemp paper used for the secret letter comes from."

Chen Chaoyan quickly took down the notes and said, "Qian Wen, Wang Da, Song Yanzhong, and Shen Jimin happen to belong to one Cao!"

The waiter gave an 'hmm'.

Lingyou said excitedly: "Would it be possible to prove who the murderer is if we find out which one is missing the white linen paper?"

Chen Chaoyan shook her head, "No."

Lingyou asked, "Why?"

Chen Chaoyan said: "Because there is no evidence."

Lingyou scratched his head, "Miss Chen, are you confused, isn't the white linen paper the evidence?"

Yuejian said contemptuously: "Stupid, the white hemp paper is the evidence, but there are no fingerprints on it. They just need to say that they don't know, and they can push it all away!"

"You're stupid!" Ling You scolded.He asked like that, but he wanted to set off Chen Chaoyan's cleverness, who cares about her speaking up!

Yuejian snorted coldly, "Miss Chen's ability to solve cases and conduct autopsies is real, and you didn't boast about it!"

"I just like to brag, what does it have to do with you?" Ling You said.

"I just can't get used to you, how?" Yuejian replied.

It's not once or twice for the two of them to confront Maimang with needlepoints. Chen Chaoyan has long been used to it. Seeing that Xie Xuan didn't care, he continued what he said just now: "Ma Huai's reason for entering the county guard's mansion and the three secret letters Start to re-investigate, I wonder if the prince has anything to add?"

Xie Xuan knocked on the table, "No."

"Qian Wen doesn't know martial arts, and Zhou Zhongcai didn't go to Yunliang Pavilion on the night of Zhou Zhongcai's accident. Although he had business dealings with Yingou Cabinet, according to the preliminary investigation results, his life is relatively simple. He is almost a county guard. The two points and one line between the government and the family, and Zhou Zhongcai, the Zuo, Shi, and Yamen servants, do not have much private contact. My opinion is that we can temporarily rule out his suspicion first.” After Chen Chaoyan finished speaking, he watched To Xie Xuan, "What does the prince think?"

Xie Xuanqian hooked the corners of his mouth imperceptibly, "Yes."
