The four adults went to battle in person, and after an hour, they finally matched all the fingerprints.

Some people are happy and some are worried.

Wei Xiancheng knew that he had been severely humiliated by Li Fei this time, but he still felt unwilling to do so.

His jealous and angry eyes scanned all the objects, his eyes lit up, and he hurriedly attacked before the county magistrate announced the results, "Li Fei, why didn't you show the fingerprints on the stones and dead wood? Did the extraction fail?

?”

Chen Yuan had already prepared for this question and looked at Liu Yanchun.

Everyone knew that she wrote a piece of paper to Liu Yanchun with answers to many questions, so everyone looked at him one after another.

Liu Yanchun didn't seem to be able to stay up late. It took him a while to realize what he was doing and took out a piece of paper from his arms.

After searching for a long time, I finally found the answer. "Li Fei said that the reason why she used utensils of different materials for experiments was because she wanted to know what utensils can be extracted and what utensils cannot be extracted. According to her verification, utensils with smooth surfaces can be extracted.

Fingerprints cannot be extracted from objects with rough surfaces."

"No method can be perfect." In Ge Xianwei's view, the method of extracting fingerprints can already help solve the case. "This shortcoming is nothing at all."

However, Wei Xiancheng was an expert at exploiting loopholes. "I don't think so. From now on, everyone will know the flaws of this method. The murderers no longer use smooth weapons to kill people, but instead use rough stones picked up by the roadside to kill people.

Then wouldn’t the method of extracting fingerprints be useless?

Or the murderer used a weapon with a smooth surface to commit the crime. As long as the fingerprints on the weapon are wiped off, the fingerprints cannot be extracted using these methods, and everything is back to the original helpless situation. So this method is not a big deal, it is quite useless." Wei County.

The Prime Minister did not take it seriously and severely trampled on the method of extracting fingerprints, belittling it to nothing.

"This..." It sounds very reasonable. Guan Zhixian's eyes became misty after hearing this. He looked behind him at his confidant Master Wen Chongru, who had just come from the Yamen with the Yamen servants. In exchange, the other party shook his head gently, so that he would not be affected by this.

The words confused my mind.

Such strong words were so novel that Chen Yuan was amused.

Looking at the speed of information transfer in ancient times, it was impossible for people all over the country to know how to extract fingerprints.

Even in this era of information explosion, so many people know the importance of fingerprints, and relying on fingerprints to solve crimes is still the mainstream.

Chen Yuan would be a fool if he still couldn't tell that Wei Xian Cheng was targeting him.

Although she didn't know why Wei County Cheng disliked her so much.

She was just a little apprentice and had never disrespected him. How could she have offended him?

The clay figurine was also very angry. She took out the cardboard and wrote, "The Record of Purging Wrongs was written by Mr. Guo, the Minister of Punishment. The book records suicide, strangulation, fake hanging, and drowning. The imperial court distributed this book to all states.

The county provides many adults and widows with opportunities to study, and there are even manuscripts in the bookstores, which have lasted for more than ten years.

So did the murderer become smarter after reading the book? Did "The Clearing of Wrongs" teach the murderer how to hide the methods of committing murder? I remember that half a month ago, two cases of suicide disguised as suicide and suicide disguised as suicide were solved, so the county magistrate

Worry too much!

Even if the method of extracting fingerprints can only solve one case, the little girl will be satisfied."

Wei Xiancheng did not expect that she would be so bold as to bring out the Shangshu of the Ministry of Justice to refute him, and his face became ugly. If it involves Shangguan, if he speaks inappropriately and is sued by someone who wants to, his black gauze hat may not be protected.

Those who are barefoot are not afraid of those who wear shoes. Of course, Wei Xiancheng has more concerns than Chen Yuan, who is so poor that he has nothing. The reason for making things difficult is not at this moment, "It turns out that I think too much."

The confrontation between the two made the county magistrate on the side, with the help of Wen Chongru, confirm that the method of extracting fingerprints was definitely of great use.

Satisfied with his bet on life, Guan Zhi carefully collected all the papers and gave them to his confidant Master Wen Chongru for safekeeping.

"Li Fei, the fingerprint extraction method you came up with has been verified by me and three adults. It can indeed successfully extract and preserve the fingerprints on the objects, and it can also correspond to the handprints of the person who printed the fingerprints. This method can

It is of great use. Once the case can be solved, I will record a great achievement for you!"

With his staff at his side, Guan Zhixian wanted to understand why Wei Xiancheng said this method was worthless. Wasn't it because he wanted to deceive him into not paying attention to this method, so he robbed him and reported it to the newspaper.

So many people witnessed Li Fei's verification process, and they didn't know where Wei Xian Cheng had the courage to want to embezzle it for himself. They really regarded him as the county magistrate as a fool.

It is unrealistic for anyone to monopolize this merit. Guan Zhixian knows very well that he might as well take advantage of it, build a good relationship with Li Fei, keep such talents for his own use, and worry about losing the credit in the future?

Feeling the magistrate's fiery gaze, Chen Yuan felt that she was just a golden doll in his eyes. Fortunately, under the cover of the night, no one could see her momentary discomfort. She quietly lowered her eyes and bowed to the magistrate.

The grace of "knowledge".

Guan Zhixian, who was on the rise, couldn't sit still at all.

It just so happened that at this moment, the arrogance of Wei Xian Cheng, who had always suppressed him, was suppressed. He was now the legitimate number one person in Weiyu County, and he had the confidence to speak, "It just so happened that the method of extracting fingerprints was verified, and I feel that today is a good day."

, it’s better to choose the day than to hit it. Let’s solve the case in one go.

Originally, I planned to ask the yamen servant to bring the murder weapon from the yamen to extract fingerprints, but considering that the bumps on the road might damage the fingerprints on the murder weapon, I had to trouble Zeng Wuzuo tonight. Li Wuzuo and I went back to the yamen to collect the fingerprints.

The fingerprints on the murder weapon have been extracted, and the relevant suspects in prison will be interrogated, the case will be closed as soon as possible, the wrongdoers will be cleared of their grievances, and the real murderer will be caught, so that my heart will be at ease."

Of course, Chen Yuan would not refuse the order from the county magistrate to solve the case as soon as possible. She could also talk to Wang Qi, so she nodded and agreed.

And she was quite happy, just now the county magistrate admitted that she was a traitor.

She looked at Zeng Chi and Zeng Shuisheng. They were all happy for her, but Liu Yanchun didn't look happy... It's just that it was normal for him to feel unhappy since she changed her job so quickly.

After packing up the tools for extracting fingerprints and putting them into a special wooden box that could hold brushes and jars, Chen Yuan was worried about how to get back to the county government office when Liu Yanchun came to her with two people carrying a sedan.

Chen Yuan was about to thank Liu Yanchun for his attentiveness, when he saw him glance at her with disgust and said, "Tsk~, don't even think about me taking you riding, ugly woman."

"..."

Chen Yuan kicked him in the back, thank you! A dog can't spit out ivory.

He was so unhappy seeing her in the limelight tonight. He even went back to his old ways and called her an ugly woman. What a bastard.
