"So what if it's revealed? How can I extract it onto paper and keep it for safekeeping? These things are slippery. The yamenmen take them here and there. If they are accidentally wiped off or broken, how can they be used to compare the suspects?

Fingerprints?" Wei Xiancheng found the problem professionally. "Or, call a painter to draw directly based on the fingerprints on the object?"

The powder revealing method was something he could think of. Wei Xian Cheng really didn’t realize how strange it was, “On these instruments of different shapes, the fingerprints are not necessarily flat, and the fingerprints on the flute even surround the cylinder.

, one misunderstanding can lead to a misunderstanding, and what will happen if the wrong person is arrested?"

"The iodine fumigation method is amazing because the two changes in color made everyone look at Li Feigao. This is also her little cleverness. What's more, the magic of this method is that the original fingerprints are hidden on the paper, and it just makes the fingerprints visible."

Wei Xian Cheng scolded his mouth dry, picked up the tea cup and moistened his throat, then blew his beard and pointed at Chen Yuan and scolded, "Actually, Li Fei, you didn't take the fingerprints as you said at the beginning. Let the fingerprints be taken."

Appearance is not considered a merit. Everyone can think of applying powder to make the fingerprints appear. It's just a matter of time. You are just seizing the opportunity to deceive the superior by exaggerating. Let us go all the way for you in the middle of the night in vain. You won't even get half a year's salary as a fine.

It’s too much.”

Under the cover of night, Liu Yanchun glanced at Wei Xian Cheng coldly. Hindsight was not uncommon, but this was the first time he had seen such a high-sounding and shameless hindsight.

Even just making the fingerprints visible was a great achievement. Wei Xian Cheng actually wanted to cover up all the little girl's achievements with exaggeration.

What is right and what is wrong? Even if it is just the current benefits of fingerprints, does Wei Xiancheng really not understand?

He understands so well.

He doesn't want others to understand.

He wanted to mislead the inexperienced county magistrate into thinking that this was a half-baked idea that was incomplete and not worthy of being presented to the emperor.

Liu Yanchun inadvertently turned his head and glanced at Guan Zhixian, and found that this time he did not show disappointment or panic after Wei Xian Cheng's provocation. Instead, he completely ignored Wei Xian Cheng's words and looked at him intently.

Ahead.

Narrowing his eyes to hide his myriad thoughts, Liu Yanchun also turned to look at the young senior sister Guan Zhixian was looking at, and slightly curled her lips. He knew that she never spoke nonsense.

Even if she is mute and unable to speak, she will still "walk the talk".

Just as Wei Xian Cheng finished criticizing Chen Yuan, everyone watched the little girl take out something as transparent as a cicada wing and as big as Pai Gow, and put it on the white fingerprint on the inkstone.

Everyone had speculations in their minds and did not dare to disturb her. They watched patiently as her skillful hands gently and slowly tore it apart. The white fingerprint glue on the black inkstone was completely removed by the transparent paper.

Surprise filled the face of Guan Zhixian, and he shouted, "The fingerprint extraction was successful! Bring it up quickly and let me see."

Lieutenant Ge Xian was also looking forward to it. This thing as transparent as cicada wings was soft and thin, and could stick to powder fingerprints. It immediately dispelled many worries in his heart. He originally thought that he would have to wait for a capable person in the long years to come.

When it comes to solving fingerprints on more complex objects, I didn't expect the little girl to think so thoughtfully.

Zeng Chi also touched his white beard with joy. This apprentice was even more powerful than him. How could he accept such a genius? I don’t know that her mind is always full of whimsical ideas. For those old cases, strange cases

Can you also think of a solution...

Chen Yuan was speechless and refused the magistrate's order. Liu Yanchun smiled and cupped his hands, "Please wait a moment, magistrate, while the second senior sister extracts all the fingerprints, marks them, and ensures they are accurate, and then submits them immediately."

"Okay, okay." Guan Zhixian also saw Chen Yuan pasting the fingerprints on the paper again and writing something on the side with a pen. He also knew that he was too anxious, "Take your time, don't be in a hurry.

"

Chen Yuan pressed the extracted fingerprints onto the various colored papers prepared early in the morning.

The white powder fingerprint is affixed to the black paper.

Black fingerprints, brown, red and other color powder fingerprints are affixed to the white paper.

And write clearly on the side which artifact it was extracted from, how many fingerprints there are on the artifact, the order of extraction, and the upper and lower directions.

After she successfully extracted and saved all the fingerprints, she handed the final product to the county magistrate.

Guan Zhixian carefully took the four pages of paper. He felt that he was holding his future in his hands and was worried that he would tear the papers if he exerted even the slightest force.

He scanned the paper with clear and distinct fingerprints, and the excitement was hard to explain to ordinary people.

For such an important verification step, the county magistrate had to go through it himself. How could he rest assured that he would only let others verify it? "Wei Xian Cheng, Ge Xian Lieutenant, Xiao Chief Secretary, come, let's verify it together."

"yes!"

Regardless of the county magistrate's orders, Ge County Lieutenant will verify them one by one.

At this moment, Wei Xiancheng already understood that it was useless to say anything else. The mute woman would never fight an uncertain battle. She was a thoughtful person, and these fingerprints could definitely be matched one by one. She didn't say anything, and she spoke with facts.

, but made his various fault-finding actions just now look like a clown.

He just wanted to be quiet at the moment, and it would be best if no one noticed him.

There is the enthusiastic Guan Zhixian, and the Gexian Lieutenant who is actively verifying the case just for the convenience of solving the case in the future. The dejected Wei Xiancheng and the careless Chief Xiao can only stay up late with the two of them.

During this period, Guan Zhixian quietly called the government officials and gave several instructions. Several government officials rode horses and went back again, not knowing what he planned to do.

"Junior sister, drink tea."

While the adults were verifying their fingerprints in person, Zeng Shuisheng poured a cup of strong tea and handed it to Chen Yuan who was packing her things.

Staying up late at this level is nothing to Chen Yuan, but she is happy to have strong tea to keep her alive.

In the past, she relied on coffee to stay up late. In ancient times, she didn't even have money to buy tea... It's sad to think about it.

Chen Yuan smiled and nodded to Zeng Shuisheng. This innocent and simple boy was very nice, just like the brother next door.

I took a sip of the tea. In fact, the tea is not that good, but it is naturally rich and strong. The overly astringent taste can also wake up the mind.

Liu Yanchun, who didn't know when he came over, took the tea cup from Chen Yuan's hand, put it under his nose and smelled it, frowning with disgust on his face, "Brother, why are you giving this tea to senior sister, female?"

Children don’t like drinking this kind of bitter and astringent inferior tea.”

Bad quality tea?

Zeng Shuisheng's face was puzzled and a little embarrassed. Is there any other tea in Yizhuang?

But this is already the best tea that can be produced in the Yi Zhuang. Then I thought about it, the junior sister and junior brother were all young ladies in the capital in the past. They never drank any good tea. No wonder they never asked grandpa for tea, they only drank it.

White water, they must not be used to drinking this tea.

He suppressed the grievance in his heart, but this was also his grandfather's heart. He saw that the junior sister had worked hard for so long before asking him to help bring it over, but Zeng Shuisheng didn't want to disgrace her grandfather, "Then I will buy some good tea tomorrow.

Invite junior sister to eat."

Liu Yanchun put the tea cup on the table and said nonchalantly, "What good tea can you buy with your little money?"

"..."

Liu Yanchun's words were too unpleasant tonight. Chen Yuan pushed him and asked him to pay more attention to what he said.
Chapter completed!
