Chapter 169 Using the Enemy (Part [-])
Hearing that Yunxi spoke so convincingly, everyone couldn't help stepping forward curiously, wanting to see what the evidence was?
Only one person did not step forward, but moved two steps back, and stood silently behind Tang Qixing's bed, with one hand pressed on the saber at his waist pretending to be casual.

Yunxi had already caught this scene in his eyes from the corner of his eye.

That person was none other than Yin Sanyu, who was loose on the outside and tight on the inside, who was frivolous on the surface but never let his guard down for a moment.

The important evidence was in front of him, and without Yun Xi's orders to wink, he also knew that he had to be prepared for Tang Qixing's sudden outburst, and he would either rush forward to snatch the evidence, or flee through the door.

In short, with Yin Sanyu's close surveillance, Yunxi can rest assured to show the evidence one by one.

Yunxi picked up the first piece of evidence, but it turned out to be a wooden board covered with a piece of white paper, with several pieces of black paper ash sticking to it.Although it was carefully glued together, it was only scorched black, and nothing could be seen.

Yunxi lifted up the wooden board carefully, and said to Han Qianhu: "This is the letter Yao Guangbai left for Yang Li. The words in it are extremely tricky. Give the letter to Mr. Yang to expose Yao Guangbai's tricks."

Han Qianhu narrowed his eyes, looked left and right, but couldn't see anything.

He frowned and asked, "Why didn't that Yang Li dare to hand over the letter to Mr. Yang?"

"Because every sentence in it is Yang Li's hatred for the Yang family, and he also regards his father's life as big as heaven, so what should a man do.

He also said that even if Yang Li compromised on the surface at this time, he was always unwilling in his heart.

The words and sentences provoked the relationship between Yang Li and Mr. Yang many times.

If such a letter is handed over to Mr. Yang, although it will deepen the trust between the two of them for a while, it will be an invisible poisonous thorn, making Mr. Yang suspicious of Yang Li.

So even if Yang Li was not persuaded by Yao Guangbai, he would not have dared to hand in the letter. " Yunxi explained calmly.

Han Qianhu sneered, "But since it has been burned to ashes by him, what can be proved, and what can be explained? It is nothing more than a pile of waste."

"Master Qianhu, please look. Although this piece of paper has been burned to ashes, Yunxi has a way to bring back the lost handwriting!" Yunxi turned around and walked into the table case, and took out another wooden box A special crystal lamp illuminated by a crystal lampshade is held in the hand.

"Joke, if burnt paper can conjure characters, wouldn't dead people be able to speak?" Tang Qixing sneered and sneered, clutching his wound on his chest.

Han Qianhu also looked disdainful.

"Scribe Yun, you are not joking. The adults are all here, so you are not allowed to talk nonsense here." Hu Ke, the old county magistrate, pinched his goatee, looking at him with a black face and a relaxed face. The smiling Yunxi warned with worry.

Although Fu Shengliang on the side trusted Yunnan Yunxi very much, after hearing this whimsical and crazy words, Qingjun's face also showed a look of worry and suspicion.

Holding the lamp in one hand and the wooden plank in the other, Yunxi bowed slightly to Hu Ke, smiled politely and yet assertively: "Master Hu, don't worry, Yunxi will never dare to deceive your lords. There is a reason."

"What's the reason?" Fu Shengliang walked forward slowly, his eyes carefully sizing up the so-called evidence in Yunxi's hand.

"Adults, please come in and take a look." Yunxi said softly, while carefully casting the light of the crystal cup on the wooden board, and slowly tilting the angle of the wooden board, allowing the light to slide back and forth on the wooden board.

According to the words, Han Qianhu, Fu Shengliang, Yang Tuo, and Hu Ke who came forward moved up and down with the movement of the board.

"Come out!" Yang Tuo was the first to exclaim.

Everyone's eyes suddenly enlarged at the same time. It was hard for them to believe that a miracle happened at this moment!

As the light moved, row after row of black and bright writing actually jumped onto the gray ashes surface one by one, floating and flashing like sparkling waves, or lit up by ghosts and gods!
"How...how is this possible?" Han Qianhu murmured in disbelief.

Tang Qixing who was behind him didn't believe it at first, but seeing everyone's reaction, his heart felt as if he had fallen into an ice cellar, icy cold.

There is no way for ghosts and gods to show up, but they can do this. Where is this Yunxi and Yunnan?

"Could it be because of that crystal lamp? Clerk Yun, you specially asked me to bring in the brightest crystal lamp just to illuminate the handwriting?" Li Ru beside him didn't believe in ghosts and gods. There must be some special reason behind the strange sight.

The first reason he thought of was the crystal cup.

Yunxi raised her head with a smile, looked at Han Qianhu, and said with a meaningful smile: "Before answering this question, Yunxi would like to ask Mr. Han, can you read the handwriting on it?"

Han Qianhu was still in a state of shock and couldn't recover. When he heard Yunxi's question, he unconsciously moved his head a little closer.

But just when his eyes really fell on every stroke and every stroke of those sparkling black characters, his shoulders trembled suddenly.Then he slowly straightened up, with a face full of horror, and slowly turned to Tang Qixing who was lying on the imperial concubine's couch.

Even if he didn't say a word, everyone in the room understood Han Qianhu's expression.

Those handwritings were written by Tang Qixing!
At this time, Tang Qixing seemed to be a different person, quietly looking at the complicated eyes of everyone, no longer pretending to be delicate, and no longer insisting on refuting.

He just looked at Yunxi silently, expressionless, without saying a word.

"Although the handwriting is scribbled, it is indeed written by Qixing. In the past, when our grandfather was catching thieves, we, Nanzhen Fusi, had no time to find an ink brush, so we would use the charcoal pen to scribble. I don't know if I have seen handwriting like Qixing. How many times, flying dragons and phoenixes, but the words are clear and powerful, and the hook at the end is even trembling." Han Qianhu recalled with a pale face.

Yunxi nodded, "Thank you Master Han, it turns out that it is the habit of exposing the Jinyiwei to the outside world, and that is solid evidence."

"But how could there be writing on the ashes? Is it really because of the crystal cup that Li Gongfang said?" Yang Tuo asked incredulously.

Yunxi knew that the time for playing tricks was over.For the rest, you have to say some reasonable and well-founded truths to convince everyone.

But she can't explain it with the words of carbon elements and chemical reactions in later generations, right?

She then put the wooden board and crystal cup back on the table to gather her thoughts.

In just a moment, she had an idea.

After turning around, she smiled calmly and said calmly: "If it is a letter written in ink, if it is burned by fire, there will be nothing left. Yao Guangbai wanted to leave a letter for Yang Li on the spur of the moment. Not to mention that Yao Guangbai came out alone to visit the site, and it was impossible for him to carry a brush and ink with him. The brush and the tip of the brush will also be frozen, making it impossible to write at all.

Moreover, Yang Li, who is highly skilled in martial arts, and his friend Bian Boss have been searching for the source of suspicious movements inside and out. The door of the room is wide open, and Yao Guangbai can't sneak into the room to study ink and write letters.So he would choose the charcoal pen and paper that he carried with him, and write down this letter in a dark place, and then when Yang Li and others looked away from the roof and went to another courtyard to check, he opened the letter. A piece of tile hung the letter into Yang Li's room. "

"You mean, ink characters will be burned, but charcoal characters won't?" Han Qianhu asked hesitantly.

Yunxi shook her head with a smile, and corrected: "It's not that it won't be burned, but the handwriting can still be seen clearly after burning."

"How come the more you say this, the more confused you become?" Han Qianhu said with a calm face.

"Because the ink is attached to the paper, it becomes one with the paper, but charcoal writes by leaving black powder. As we all know, even if charcoal is burned, the shape is still there. Although the powder is small, the shape is still there. , as long as the paper ashes are not crushed and still maintain the overall shape, the toner left on the black paper ashes will reflect black and bright light when illuminated by light at different positions, so that people can see those writings .”

"That's right, the words written with charcoal pens, the white paper was burnt to nothing, and the handwriting can still be seen. Before the cloud clerk did it in front of me, I really saw the reflection. Words!" Standing at the farthest corner, the boss with a big beard full of chin, guaranteed Yunxi's ticket.

Hearing this, all the people in the room were shocked except for Bian Boss and Yunnan. They had never heard of it before, and the handwriting could be read on the burnt paper.

But what Yunxi said was so reasonable that they had to believe it.

"Besides this ironclad evidence, the next piece of evidence is even more ironclad!" Yunxi carefully picked up another object on the table.

"Is there any more convincing evidence?" Han Qianhu asked in surprise.

Yunxi held the edge of the utensil with both hands and displayed it in front of everyone.

"What is this? A tile?" Han Qianhu's face was even more puzzled.

"That's right, it's not only a tile, but also a glazed tile tile with a smooth surface," Yunxi explained with a smile, "What's more, it was taken from the roof of Yang Li's house, and there was a claw next to it. The hook, the rope tied to the claw hook, was stretched into Yang Li's room, and the other end of the rope was hanging Yao Guangbai's letter to Yang Li."

"But even if this tile was indeed touched by Yao Guangbai at that time, how can it be proved that it has something to do with Tang Tiqi?" Han Qianhu questioned.

Yunxi's starry eyes slightly curved, and she smiled sweetly, "Because there is a fingerprint left on it, whether Tang Ti rode it or not, you will know once you check the fingerprint."

Under Yunxi's guidance, Han Qianhu moved forward, and sure enough, he saw a small fingerprint-like trace on the smooth and shiny tile.

"Even if there are fingerprints, they are so blurry that no one can distinguish and compare..." Han Qianhu just wanted to say that the traces of the tiles are so blurred that it is impossible to make a clear comparison. Using fingerprints as evidence is simply nonsense talk.

But he suddenly remembered the miracle of distinguishing characters from paper and dust just now, and he was afraid that the other party really had a strange trick, and the second half of the sentence slipped to his lips, and he swallowed it again.

Yunxi knew Han Qianhu's doubts.

Indeed, with a fuzzy fingerprint on the tile, there is no way to distinguish the contrast with only the naked eye.

Even at the beginning of the [-]th century, hundreds of years later, fingerprinting has not been widely used in criminal evidence collection.What's more, in this Ming Dynasty, there was no microscope, no photographic imaging, no fingerprint snapshots, and then superimposed pictures with various advanced technologies.

However, Yunxi, who traveled here without any golden fingers or any high-end skills, has at least a little advantage over the ancient people with underdeveloped science and technology.

It's just seeing a lot.

For ancient people, fingerprints or paper ashes cannot be regarded as effective evidence at all.

On the other hand, Yunxi is better. On the contrary, as long as she finds a convincing method to solve the condition that the fingerprints are blurred and cannot be seen clearly, and can extract the fingerprints, then it is one of the best evidences!

"Master Qianhu, you don't have to worry. Although our Teng County is small, it is known as the thoroughfare of nine provinces. Not only have there been many scholars, but also skilled craftsmen. It can be said that there are talents everywhere, and dragons and crouching tigers are hidden everywhere." Yun As Xi said, he turned his gaze to Li Ru and smiled at him.

Hearing Yunxi's praise, two blushes immediately appeared on Li Ruqing's face.

He nodded to her knowingly, turned around and walked to the table, picked up another evidence.

Yunxi continued: "The reason why the fingerprints cannot be used as evidence is because there is no way to distinguish them. But if the fingerprints can be completely extracted, placed on another clean white paper, and then taken by the suspect The ten fingerprints, compared one by one, the truth can be revealed."

At this time, Li Ru had already walked back to Yunxi, and Yunxi put the tile next to the evidence in Li Ru's hand, and said seriously: "It just so happens that our Teng County workshop official, Li Ru, is a talented man. Officials are not only very proficient in building bridges and fortifications, but also have ideas about some gadgets. The almost impossible task of extracting fingerprints was successfully overcome by Li Gongfang!"

Following Yunxi's guidance, everyone's eyes turned to Li Ru's face.

Among them, Yang Tuo's gaze was the hottest, and he felt even more honored than being complimented and praised himself.

The corner of Yunnan's mouth twitched unconsciously.

He clearly entrusted Yunxi himself with the task of conquering technology before, but he did not expect that this living ancestor would make the best use of everything and people, and assign it to more suitable people.

Well, friends and enemies change with the change of positions and interests.

Not sticking to the rules, not sticking to the old law, and not going into dead ends are the basic qualities of a prison inference official. This time, she can barely pass the test.

"Scribe Yun has won the prize, and his subordinates came up with the idea of ​​using the hard yellow method to extract fingerprints entirely under the inspiration of Scribe Yun."

"Hard yellow method?" Fu Shengliang's eyes lit up, and he asked, "Is it the kind of light-transmitting paper specially used for copying by literati?"

Li Ru nodded, "That's right, it is this kind of copying paper made by the hard yellow method. The so-called hard yellow method refers to applying a layer of yellow wax on the extremely thin and transparent rice paper, and then testing it with an iron specially designed for ironing the paper." Evenly, change the paper properties of the paper, and harden it. The paper becomes transparent.”

"Even if it becomes transparent, how can fingerprints be obtained?" Hu Ke squeezed his goatee, and the wrinkles on his face deepened one by one.

"Extremely fine charcoal powder!" Li Ru replied emphatically.

"Fine charcoal powder?" Everyone was even more puzzled.

Li Ru carefully and patiently explained the reasons to everyone one by one.

At this time, Yunxi had already put his hips on his hips and laughed countless times.

Hahaha!
Refined charcoal powder, if translated into modern words, is pencil dust!
At that time, she racked her brains and struggled to design how to reproduce fingerprints.

Helpless, after the college entrance examination, she was replaced by someone, so she abandoned herself and went to the society. She didn't persevere in continuing her studies, and her poor knowledge of physics and chemistry in high school had long been thrown to the claws.

If she knew that there was today, she would definitely swear that no matter how big the setbacks were, she would not give up on herself, nor would she give up on her further study and cultivation.Never punish yourself for the injustice of this society and the mistakes of others.

After thinking about professional knowledge for a long time, she finally gave up this path sadly and helplessly, and instead recalled all kinds of news that left an impression in her mind in her previous life. Modern society is so advanced, it is difficult to protect that little common sense that has not been noticed That would do her a favor.

Just when she turned around, a familiar scene appeared in front of her eyes!
It was a pencil game she played with a group of children when she was young.

At that time, she rubbed a finger on the notebook full of pencil words, and that finger would be stained black by the pencil dust. She did not wipe off the pencil dust, but pressed her fingerprints on the transparent tape On the viscose side, an exceptionally clear black fingerprint appeared perfectly.

To this day, she still remembers how happy she was when she pressed cute and small fingerprints on those clean and transparent tapes.

Thinking of this, she slapped her head violently, and remembered a scene she had seen while watching TV.

The criminal investigators evenly sprinkled extremely fine charcoal lead powder on the fingerprints left by the evidence, and then covered a piece of paper, or something, with a fine-bristled brush to sweep over the paper over and over again.When the piece of paper is uncovered, the complete fingerprint is engraved on the paper, and finally the camera is used to capture the picture to form a picture, and the fingerprint extraction work is complete.

But thinking of this, the problem arises again.

Use scotch tape method, there is no tape at all in ancient times.

Let's use the paper reproduction method. First, she doesn't know what kind of paper appeared in the flashing picture on the TV at that time?It is estimated that ordinary white paper will definitely not work, and what is more terrible is that the fingerprints engraved with pencil dust are not easy to preserve. When the paper is shaken, the ashes fingerprints will be broken and scattered. Without an instant camera, this method is basically useless.

However, adhering to the scientific research spirit that a living person cannot be suffocated by urine, Yunxi tried to find a way to combine these two methods and find a substitute in ancient times.

First, keep the method of painting fingerprints with pencil dust, and second, replace the unknown paper with sticky scotch tape, directly engrave and stick the fingerprint gray print.

In this way, not only the clarity of the fingerprint is ensured, but also the persistence of the fingerprint is ensured, and the fingerprint extraction method is perfectly born!
With this plan in mind, she immediately approached Li Ru, who is a skilled craftsman, and first asked him if there is any transparent and sticky paper in the world today.

Li Ru immediately thought of the hard yellow method, because the copying paper made by the hard yellow method is not only transparent, but also contains yellow wax. Once it is slightly heated and covered with fine charcoal powder on the fingerprints, it can stick to it. The whole fingerprint.

Under the guidance of Yunxi, Li Ru did a lot of experiments on other tiles.After trying different fineness of the powder, the degree of heating of the hard yellow paper, the type of thin paper on the surface, and the uniformity of the force of different fine-bristled brushes, Li Ru finally found a tried and tested one. the right way.

Li Ru on the other side had already explained all the methods, and everyone suddenly realized.

It turns out that there is such a simple and effective extraction method.

Although this method was successfully experimented by Li Ru, in people's hearts, everyone is impressed by Yunxi's astounding whimsy.A series of loud laughter suddenly resounded in the whole hall.

People looked sideways, but they saw Tang Qixing behind him holding on to the armrest of the imperial concubine's couch and laughing nonstop.

"Oh, my Tang has lived so long, today is really an eye-opener! He really deserves to be a genius boy with a family background of 600 years. He is really exciting and powerful!" He laughed until tears flowed out of the corner of the eye.

Looking at Tang Qixing, Yunxi suppressed his smile, his eyes were deep, and he said seriously: "Although it is wonderful, I just wonder if Tang Tiqi has the guts to present ten fingerprints one by one?"

　O(∩_∩)O haha~, I am a small footnote
　　Today I'm going to talk about hard yellow paper

　　Hard yellow paper, the more expensive artistic processed paper created by the working people in the Tang Dynasty.It is used to write scriptures and copy ancient posts.On the basis of dyed yellow paper in the previous generation, people in Tang Dynasty evenly coated wax on the paper to make the paper shiny and beautiful, and it was called hard yellow paper.Paper translucency can be used to make copies of calligraphy and painting works.In Northern Song Dynasty Dong You's "Guangchuan Book Postscript, Volume [-]", "People today do not examine it, but actually get hard yellow paper, which is called the ink left by the ancients."

　　It can be said that the hard yellow paper is the crystallization of the wisdom of the working people in our country. It can be said that the transparent paper is made of transparent paper by hand, O(∩_∩)O haha~
