Yipin County Magistrate: Start with invincibility

Chapter 282 Extracting Fingerprints as Evidence　
Two yamen servants brought a book case to the center of the courtroom. Qin Feng carefully put the treasured knife away, and then lightly sprinkled toner on it, covering the entire blade of the precious knife with a thin layer.

Then, he lowered his head and blew off the top layer of toner, and ordered someone to take a stack of cut, palm-sized silk as thin as a cicada's wing, and put those silks next to each other carefully. Covered on the treasure knife.

The common people and the servants all frowned, watching Qin Feng operate, not knowing what Qin Feng was doing.

"Master Qin, what are you doing?"

"I don't know, do you want to burn this treasured knife with fire, so that you can verify whether it has been used recently?"

"Ah? Burning with fire, does it still have this effect?"

"I guessed randomly, because the box in Mr. Qin's hand is obviously toner..."

"Toner?"

"That's right, Mr. Qin bought it at a charcoal seller with a lot of money that day. The charcoal seller ground it fresh and sifted it carefully through a flour sieve."

"So that's how it is. Master Qin has a lot of tricks. But why hasn't he lit the fire yet?"

On Qin Feng's side, the silk has been gently removed, the treasured knife is turned over, and it is operated again according to the order just now.

After finishing the operation, five or six pieces of silk had already been laid out on the table.

On the silk, many lines have been printed, some are clear, some are blurred, circle by circle, like annual rings.

Qin Feng's move is exactly to extract fingerprints.

"Old Wan! Take Ji Bugang's fingerprints as I ordered yesterday."

"Yes!"

Wan Kunming responded, and immediately ordered two yamen servants to detain Ji Bugang, rubbed all his ten fingerprints, and sent them to Qin Feng.

"grown ups……"

"Well. Come on, let's compare it together, as long as we find one, it will be enough to convict him."

The two of them buried their heads in the comparison, worked for a while, and soon got the result, and there were more than one fingerprints that matched.

There are three fingerprints, which are extremely clear, which can correspond to Ji Bugang's right thumb, index finger and ring finger.

Qin Feng suddenly showed a comfortable smile.

He has read some materials and knows the basic methods of extracting fingerprints, but the materials used in the materials are all special fluorescent powders, or powders with very strong adsorption properties.

This ancient man definitely couldn't find that kind of powder, so he could only use finely ground carbon powder as a substitute.

He tried it himself last night, but the effect was not ideal, it was barely usable.

Unexpectedly, in the court today, the fingerprints extracted were much clearer than when they tested them by themselves last night.

Qin Feng picked up the three fingerprint patterns and flashed them in front of Ji Bugang: "This is the evidence that you have used this knife!"

Ji Bugang frowned tightly, looking at the thing in Qin Feng's hand, wondering how it could be used as evidence.

Not only Ji Bugang, but even the surrounding people were very puzzled.

"Master Qin, what is the meaning of this? How can a few pieces of silk become evidence?"

"Yeah, it's not on fire either..."

"Shhh, don't talk. I don't think Mr. Qin will be aimless. There should be an explanation."

Of course there will be an explanation.

If you don't explain to the people what the fingerprint is, this evidence is really useless in ancient times.

"My folks, please look, the pattern on this silk is nothing but the fingerprints that each of us will have on our hands."

"Everyone may not know that it is not uncommon for people to look alike, or even exactly the same, but the fingerprints are basically unique. If you don't believe it, you can come forward Come on, print your own fingerprints on paper, put them together with other people's fingerprints under the sun, and see if they can overlap."

"I can leave my words here. No two people's fingerprints can completely overlap!"

"Using some techniques, the officer extracted the appearance of the fingerprints, rubbed them on paper, and compared them with Ji Bugang's own fingerprints. If they match, it will prove that he has indeed used this knife!"

Qin Feng said a few words to express his meaning.

This is the first time the common people have heard of such a thing, and quickly compared it with those around them. Some fingerprints are concentric circles, and the naked eye can't tell the difference, so many people among the common people are skeptical.

Qin Feng directly picked a few people who felt that they had the same fingerprints as others, and asked them to print their fingerprints on the silk, cover them with toner, and then blow them away to leave their fingerprint patterns.

Qin Feng asked them to put them under the sun, and stacked two pieces of silk that were as thin as cicada's wings for comparison.

Those people worked hard for a long time, but they couldn't find two identical fingerprints, so they couldn't help being amazed.

"Master Qin's words are indeed true! Wang Er's and mine's fingers looked like they were carved out of the same mold, and the fingerprints couldn't overlap!"

"Yeah, not only can't overlap, it's still far away!"

Qin Feng looked at them with a smile and asked, "Do you believe it now?"

"I believe it, hehe, I believe it!"

The commoner immediately retreated into the crowd and shared it with everyone, and the surrounding people became chaotic for a while.

Qin Feng waited patiently for a while.Because he knew that the evidence in his hand could truly become evidence only if everyone had the recognition that their fingerprints were unique.

The people discussed for a long time before gradually quieting down.

Then Qin Feng put the three pieces of silk that he picked out together with Ji Bugang's fingerprints on the paper and put them under the sun, walked around in front of the people in the front row, and showed them.

"Oh, it really overlaps!"

"Second Brother Ji, didn't you say that you haven't touched that knife for half a year? Didn't you say that you wiped it carefully? How could it still leave such fingerprints?"

"Second Brother Ji lied!"

"It seems that Lin Cuiling was really killed by him. He was so insane that he even killed his first wife! It's cruel!"

The people accepted the fingerprints as evidence, and immediately believed Qin Feng's accusation against Ji Bugang.

Because Ji Bu said just now that he had never used the saber, and that he had carefully wiped the saber before hanging it up, but now the facts have proved that those are all lies!

Who would tell a lie?Naturally, the criminal who wanted to cover up the truth!
After walking around, Qin Feng came to Ji Bugang with the evidence, sent him to him, and asked, "Ji Bugang, what do you have to say now?"

"Why on earth did you kill Gongyang Lian, Lin Cuiling? The cause and effect of the incident, what is it, and it's not true!"

The evidence was conclusive, Ji Bugang finally lost his toughness just now, drooped his head, and said nothing.

Qin Feng chuckled: "Okay...you don't say it. Then let me say it!"
