I'm a Super Cop

"Flaws?" Master Kang likes this word most, especially at this time when Zhu Ruiping is so aggressive that he can't breathe.

Gu Chen's words are undoubtedly timely rain.

Secretary Zhou also stared at Gu Chen with wide eyes and asked, "officer Gu, you said that Zhu Ruiping's mortgage is fake. What evidence do you have?"

"Yes, you What evidence do you have? How can I say this mortgage is fake? You are slander

Just now, after hearing the conversation between Secretary Zhou and Gu Chen, Zhu Ruiping also knew that Zhu Ruiping was standing in front of him and accused him of being a forger of the mortgage of the house deed. He was also a policeman of the criminal investigation team of Furong sub Bureau of Jiangnan City. He was a little nervous.

But the tension returned to tension. When the situation reached this point, Zhu Ruiping also could not retreat. He never wanted to give in.

"Don't pretend to be aggrieved." Gu Chen looked at Zhu Ruiping, then turned the yellow paper back and forth, and said with a smile: "as far as your handwriting is concerned, although it is the handwriting of Master Kang when he was alive, it is not necessarily written by Master Kang."

"Why What do you mean Zhu Ruiping looks at Gu Chen.

as like as two peas, "you can write a master's handwriting. You can copy a handwritten copy of the handwriting exactly like the old man's calligraphy and habits."

"Ah?"

"Can you copy it?"

"Why didn't we think of it before?"

"That's right. If you are a master of calligraphy, you can write this kind of handwriting. For example, Wang Xizhi's calligraphy in those years has been thoroughly understood by many people. If the forgery is put in the exhibition hall, it will be just like the real one."

After listening to Gu Chen, many people suddenly realize that it is entirely possible for this situation to happen.

Zhu Ruiping refused to accept this and said, "but But this is just your one-sided statement. It is just a hypothesis. There is no real evidence at all. Why do you say that this mortgage is forged by copying handwriting? "

"Yes." Standing behind Zhu Ruiping, an executive immediately stood up, pointed to Gu Chen's nose and said, "you're a police officer, you're ridiculous. Do you mean to copy? This is something dated. The paper is yellowing. It is obviously something written by Master Kang himself

"You don't say it's OK." Seeing the aggressive executives of the other side, Gu Chen just shrugged his shoulders and walked easily to him.

Short Gu Chen half of the head of Zhu's executives, and immediately quickly back up two steps, and Gu Chen to maintain a relatively safe distance, said: "it is."

"Have you ever considered why this paper turns yellow?" Gu Chen's soul torture, suddenly let the opposite Zhu family executives is also a Leng.

He only knew that the paper would turn yellow after a long time, but he didn't really think about why it turned yellow.

"I can tell you." Gu Chen chuckled and took two steps forward: "because the paper is made of acid bleach. Although it has been neutralized before leaving the factory, there will still be residual substances left on it. Over time, the paper will be oxidized and will turn yellow. In fact, the paper composition is oxidized."

"Originally So it is. " Zhu's senior management was stunned. The arrogance just now subsided.

Gu Chen then went to Zhurui plane and said, "lignin is one of the main components in plant fiber. It has aromatic characteristics. It is a compound containing carbon, hydrogen and oxygen. According to chemical analysis, lignin contains the following functional groups."

"Wait a minute." Zhu Ruiping suddenly interrupted Gu Chen and asked, "what is the" functional group "you are talking about

Gu Chen smiles: "functional groups are atoms or atomic groups that determine the chemical properties of organic compounds. Can you understand that?"

Zhu Ruiping didn't understand.

I was a student. Although I went to America to study abroad, I was just a pheasant university.

However, Zhu Ruiping still has some vague concepts about atoms and atomic clusters.

"You Say it Seeing Gu Chen staring at himself all the time, Zhu Ruiping had to shut up again.

In fact, I said that the carbonyl group in the eye contains hydroxyl groups

"Lignin is white or nearly white, insoluble in solvents, fragile in texture, soluble at high temperatures, and its solution is milky white or dark brown."

"Because lignin contains various functional groups, its chemical properties are relatively active, such as sulfonation reaction, lignin into soluble lignosulfonate, oxidation into soluble chlorinated lignin."

"But lignin is the easiest to oxidize, especially in the presence of light, high temperature and alkali."

"And modern paper contains more lignin, so newsprint is very easy to yellow and brittle, not easy to long-term preservation."

"That's right." Hearing this, Lu Weiwei couldn't help interrupting: "my family's old newspapers, the most easily yellowing, and it is yellow and crisp, you can easily crush the kind.""I have it at home, too." Nie Xiaoyu also can not help saying a few words: "this kind of old newspaper, my family is, really with Gu Chen brother said, originally this also includes so many chemical factors in it."

Zhuruiping was obviously confused by Gu Chen.

He saw that the young man standing in front of him was obviously a bully.

At least, he can blurt out this seemingly complex knowledge, which is enough to see how strong the knowledge reserve in his mind is.

Ordinary people, even if they can see it in the library occasionally, they don't have to remember such a prison.

But the young man in front of him can, which is a little scary.

Seeing zhuruiping no longer spoke, Gu Chen smiled and said, "so, it can be seen that the paper raw materials contain plant fibers, especially lignin, pectin, fat, pigment and other ingredients, which buried potential factors for the paper harm, so these problems will occur, but you yellow paper..."

Gu Chen deliberately in this yellow mortgage corner, with a finger gently scraped.

But to everyone's surprise, the paper was intact, Gu Chen continued to push a button, which began to be buckled in the next corner.

"Tut, the paper of 20 years or so, the crispness is not like 20 years ah." Gu Chen's eyes looked at zhureeping again.

Zhuruiping is a little yellow, even a little bit of a retreat, then, another tall and thin, with black frame glasses, a fine-looking middle-aged executive, appeared next time around zhureeping.

He was like a general of staff, showing a slight disdain to Gu Chen's question.

"I said, boy, oh no, it should be called Comrade police, right?" The tall and thin glasses made men disdain.

Gu Chen shrugged: "whatever, do you want to say anything?"

"Hum." The man with high thin glasses snorted and said, "you are right, but you should know that if I can do these three points, the paper will turn yellow or reduce the embrittlement, which can be realized completely."

See each other confident, Gu morning nodded, reached out and said: "I wish to hear it in detail."

"This is the first." The man, learning the way he was just looking at the morale of Gu Chen, raised his head and carried his hands back, went to Master Kang and said:

"the first point is to reduce contact with the air, the second is to reduce the contact with water, and the third point is to reduce the contact with the sun."

Gu Chen holds his chest in his hands, and after thinking for a few seconds, he nodded: "yes, you are right."

Seeing Gu Chen's approval, the tall thin glasses man who seems to be a bully looks like, he is quite proud at once, and says:

the contact with the air can not be avoided by ordinary people, but it can avoid contact with water and sunshine as much as possible. "

"If you don't use some books, you can try to put them in plastic bags and seal them out when they are used."

Gu Chen nodded: "please continue."

The man with high thin glasses smiled and walked to Secretary Zhou: "the storage period of paper usually should not exceed one year or more. Even if the conditions for keeping paper are better, the paper will change color and deteriorate if the paper is stored for too long."

"If the paper is stored for two years, the paper will turn yellow and de powdered, the newsprint will turn yellow and brittle, the packaging paper will change color, the strength will be reduced, and the yellow paper and the box board paper will become moldy and deteriorated."

See scene all of a sudden silence, as if this is his own stage, high thin glasses men immediately proud not to do not want, mouth corner raised a confidence arc.

"So in general, the white paper we use is made of the fiber pulp that the paper mill processes the tree fibers and then spreads it on the flat plate to dry it," he continued laughing at Gu Chen

"But you can imagine the color of the cross-section of the trunk, the wood fiber is slightly yellow, so in industry, the paper is bleached with sulfur dioxide."

"But the bleaching of sulfur dioxide is not as stable as chlorine, it is easy to lose the bleaching effect by oxidation of oxygen to sulfuric acid, so that the color of wood fiber itself is violent. It is revealed, which is what police officers have said before."

Gu Chen continued to nod, but did not speak.

"Sulfuric acid can destroy the fibers in the paper." The thin glasses man raised his right index finger, just like a tall man teaching with a group of learning slag. He said confidently in his words:

"therefore, the paper will become brittle, in addition, the paper will become brittle due to the paper being too dry and the oxidation of lignin in the paper will also cause the fiber to break and make the paper brittle."

"So, if I can do the three points I said before, what about the yellow paper? The paper embrittlement, theoretically, can appear you just experimental requirements. "

"OK." Zhu Ruiping saw his senior management can PK Gu Chen, the whole people suddenly excited.

He almost didn't shock the man's black glasses when he hit him on the shoulder of a tall thin glasses man.

The man of high thin glasses immediately helped the glasses, and was proud to arrange his coat, and he raised his chest and breathed up. He looked at Gu Chen all the time like a defeated cock.Ludwig froze.

Nie Xiaoyu also froze.

Including police officer Wang, Master Kang, as well as Bai Xiaolan and Wu Jun of the TV station, as well as Secretary Zhou and the foreign businessmen, they were all shocked by the words of the tall and thin glasses man just now.

He directly denied Gu Chen's experiment with direct theory and made a reverse proof.

It is proved that there are special circumstances in the cases mentioned by Gu Chen.

High salary is not for nothing. You have to stand up at the critical moment to share the worries and solve the difficulties for the boss. This is the experience of the man with high and thin glasses. Don't want to feel cool.

He even wanted to clap hands with Zhu Ruiping, but because of the scene environment, he restrained.

Gu Chen suddenly covers his mouth and laughs secretly, which makes Lu Weiwei and Nie Xiaoyu not understand.

Just now that tall and thin eyed man, so aggressive to Gu Chen, Gu Chen can even laugh?

It doesn't look like Gu Chen's style?

Master Kang was also anxious: "Gu Chen, how can you still laugh at this time? That glasses guy said that, that is to confirm that their mortgage is true? "

"Master Kang, don't worry." Gu Chen also laughed and said, "they are in such a hurry to confirm that they have dug a pit and buried themselves."

"What? Dig your own hole? Bury yourself Master Kang was a little confused by Gu Chen. He said, "Gu What do you mean by that, Gu Chen? "

"Yes, Mr. Gu." Lu Weiwei, who seems to know Gu Chen very well, is now more and more difficult to understand Gu Chen's mind.

OS doesn't work?

Telepathy gone?

Why can't Gu Chen understand this wave?

Nie Xiaoyu also quickly asked Gu Chen: "brother Gu Chen, why do you say that? Are they themselves exposed?"

"Almost." Gu Chen's chest in both hands is already ready.

As if the other side in front of their jump in front of the fierce, is undoubtedly digging a hole for themselves.

Opposite Zhu Ruiping and tall thin glasses man, immediately also by Gu Chen strange calm is stunned.

Two people have never seen each other, when the opponent is speechless, the other side even snicker?

What's the operation?

Zhu Ruiping stepped forward and said, "young man, what are you laughing at? So happy? "

"I laugh that you help me to explain all the things that I want to add before, just to save me from telling you."

"What?" Tall thin glasses man a Leng, momentarily stupefied: "you mean..."

"I mean, you help me explain why more than 20 years of paper yellowing, but it can be so hard, which is another reason I want to say." Gu Chen answered directly.

Later, Gu Chen took the yellowing paper back to the public: "as the gentleman with glasses said just now, if I can reduce the contact with the air, the water and the sun, the hardness of the paper can be maintained, and it will not be fragile because it turns yellow."

"But Sir, have you ever thought that this is a piece of paper that is obviously folded and preserved."

"If it's 20 years ago, and it's folded, it should be yellow on the outside and white on the inside."

"But the inside and outside of this document." Speaking of this, Gu Chen also specially turned the two sides back and forth to the public to watch, and said casually, "however, the inside and outside of this note are all yellow, and the yellow is so uniform."

"Ah?"

"Shit, it's true."

"This mortgage is really yellow. If it is folded, it must be yellow on the outside and white on the inside?"

"This young man is right. How can this piece of paper be yellow after more than 20 years? And the color is so even? "

For a while, leaders, foreign businessmen and enthusiastic people all began to agree with Gu Chen's remarks.

On the contrary, Zhu Ruiping and the man with high and thin glasses are flustered.

The tall and thin glasses man, with his own set of high forced words, tells Gu Chen and everyone how to keep the paper yellow and crisp as before.

But he did not tell you that when the paper is folded and stored, the outer part in contact with the air will obviously turn yellow.

Moreover, there will be a color difference with the internal paper, but this is not the case on the mortgage letter Gu Chen held in his hand.

Tall thin glasses man panic, he used his own set of high forced grid words, successfully to Zhu Ruiping dug a big hole.

Zhu Ruiping's face is green now

The excitement just now was less than ten seconds, but now he felt deep despair.

At this moment, Secretary Zhou looked directly at Gu Chen and asked him, "officer Gu, that How was the yellow color of the mortgage settled? "

"I think the corner here is also damaged, and the color difference of the whole white rice paper is very similar to some years ago. If it is forged, it has to be prepared several years ago.""It's not that complicated." Gu Chen waved his hand and dismissed the encouragement of Secretary Zhou. He said faintly, "this color is obviously dyed with some kind of solution. What is it?"

Gu Chen then took it to the tip of his nose and sniffed it. Then he said, "Oh! By the way, it's tea juice. It's Mr. Zhu Ruiping who dyed the handwriting with tea juice, making the paper yellow. "

As soon as Mrs. Kang heard this, she quickly went to Gu Chen's side, took the mortgage from Gu Chen's hand, and quickly put it on the tip of her nose and sniffed it. Then she said:

"Gu Chen is right. I have been making tea for so many years. I can tell if the tea juice is as soon as I smell it. Although the taste is very weak, obviously it has been for some time, but this is definitely the taste of tea juice."

"Let me see." Another foreign representative, seeing this situation, quickly went forward to take the paper and sniffed like sister Kang: "well, yes, it's the tea juice, or the most popular tea this year."

"Show me."

"I'll see it, too."

……

All of a sudden, many tea industry senior personage, also volunteered to come to check.

Sure enough, you can not only smell the tea juice, but also guess the tea industry.

And the paper even yellow problem, also in Gu Chen's reasoning, the truth.

Zhu Ruiping was completely flustered.

He had planned out this fabricated fact carefully, but unexpectedly, he was exposed by the young man in front of him.

This young man is absolutely terrible.

In the face of many people's verbal criticism, Zhu Ruiping was afraid that he would be torn apart by the masses at the scene. After a light turn, Zhu Ruiping ran away.

"Look, Zhu ran away." Lu Weiwei, a sharp eye, found the situation.
