I am a super cop

Chapter 1779 Gold Leaf 【Two Chapters in One】

Inside the living room.

Zhao Ke's ambiguous answer made everyone hesitate.

You know, this incident was all caused by Zhao Ke's decoration.

If Zhao Ke had an agreement with the original owner, Sun Yunmei, not to renovate the house, then Zhao Ke is also responsible for this matter.

Because Zhao Ke did not follow the agreement when buying the house before.

But after thinking about it, how can there be such an agreement?It is indeed unbelievable.

"What else do you want to say? You might as well just say it straight." Feeling that Zhao Ke had something to say, Police Officer Wang also urged him to speak.

Zhao Ke frowned, and said truthfully: "The thing is like this. Although we had an agreement before, the old lady just asked that the overall decoration of the house not be changed."

"If I want to decorate my own room, she has no objection, but if I can bear the original decoration style and keep it, she is willing to sell it at a low price."

"Then what were you thinking at the time?" Gu Chen adjusted the body camera and asked again.

Zhao Ke also scratched the back of his head, and said with some regret: "It was quite strange at the time, after all, this kind of request seems too weird."

"But I thought that the old lady might say that because she has feelings for this old villa."

"As long as I don't make major changes to the overall decoration and structure of the house, I can save a lot of house purchase costs, which is quite a deal when I think about it."

"And I also like the original decoration style, so I agreed after thinking about it."

"That is to say, you violated the agreement first?" Lu Weiwei looked up at Zhao Ke and asked him.

Zhao Ke nodded embarrassingly: "Well, it's been a few years, I guess this old lady should have gone abroad to live with her relatives, friends and family."

"So, I thought I could use this time to renovate some structures a little bit, and when it's done, she can't do anything about me."

"But who knows? Although I didn't keep my promise, this old lady also lied to me. She even used a wall alone in the living room to seal up a secret room."

"Then you and this old lady, Sun Yunmei, are both responsible for this matter, so you still have the nerve to find her? You are not afraid..."

Thinking of this, Lu Weiwei suddenly hesitated to speak, and hurriedly asked Zhao Ke: "Eh? Zhao Ke, did the old lady say that if you violated the rules, you will be punished for the agreement you signed earlier? Is there such a clause? ?”

"Uh……"

Hearing Lu Weiwei's remarks, Zhao Ke seemed a little flustered.

Yuan Shasha got tricky at the first glance, and directly pointed out: "There are still some, right?"

After the voice fell, the air at the scene was suddenly quiet for a short time.
Zhao Ke scratched his head, and said in a bad mood: "Actually, there are penalty clauses. It is nothing more than a certain penalty. The proportion is quite high, almost the difference of the original house price."

"Then you're still looking for the old lady?" Police Officer Wang said with a dazed expression, "Get her back, and then you'll pay her a fine?"

"But I don't want this house anymore." Zhao Ke also said it very bluntly, bluntly:
"The problem now is not whether to pay the fine, but whether my wife or I want this house anymore."

"Even if we have to pay a penalty, we admit it, but we hope to return the house to the old lady, and she will return the purchase price to us."

"Hehe." Hearing such a request, Lu Weiwei couldn't help laughing twice, and said:
"Zhao Ke, do you think this is possible?"

"Impossible, but I have to fight for it." Zhao Ke is also a bit overwhelmed now, and keeps telling everyone:

"In the current situation, it is obvious that although the house price has risen a lot compared to three years ago, if this incident happened in my house, it must not be sold."

"If I don't hurry to get the money back now, won't I be taken advantage of?"

Zhao Ke's answer really made Police Officer Wang a little powerless to refute.

According to the normal logic, if Zhao Ke breached the contract for decoration, he would have to pay the old lady a certain fine.

But the old lady also concealed the fact that there was a secret room in the old villa.

This will inevitably lead everyone to think that this old house was a haunted house before.

Now everyone's attitude towards the haunted house is not very friendly.

Not only will it affect the housing prices in the surrounding areas, but it will also be difficult to sell your own house.

So this is Zhao Ke's true intention that he would rather pay money in multiple places than find a way to return this old villa to the old lady.

Lu Weiwei sighed faintly, and said angrily: "So you, Zhao Ke, still have so many thoughts hidden in your heart? You should have said otherwise."

"It's... hard to say." Zhao Ke put his left hand on his forehead, also speechless.

You know, whoever this matter happens to is a burden.

Gu Chen interrupted the speech with a wave of his hand, and continued: "I don't care about these things now. In short, the whereabouts of the old lady Sun Yunmei are currently unknown, and we are actively looking for them."

"It would be the best if you can find her, but please prepare for the worst."

Why did Gu Chen say that?
Obviously, Sun Yunmei may not be alive anymore, Gu Chen knows this better than anyone else.

It's just that it's hard for Gu Chen to tell Zhao Keming about this matter.

But Zhao Ke is not stupid. Ever since Gu Chen gave him the whereabouts of Sun Yunmei, Zhao Ke went to North Ridge to search for Sun Yunmei's whereabouts, but to no avail.

Originally, they wanted the police to help find Sun Yunmei, but now the police have come to the old villa, which shows that the police have gained nothing.

"The worst plan is not to find Sun Yunmei, right?" Zhao Ke asked.

Gu Chen nodded silently.

"That is to say, my house may not be sold, right?" Zhao Ke asked again.

Gu Chen slowly replied: "It's not realistic for you to sell the house back to Sun Yunmei, but it may be possible to sell it to someone else."

"No." Zhao Ke shook his head directly and said depressedly:
"There is a problem with my house, and I can't explain it clearly. The rooms in several old houses next to me are affected."

"Especially now that the original owner can't be found, and I can't explain it clearly. Now there is no one to testify. There was no murder in this old villa. What do you ask me to do?"

"We will find a way to prove it to you," Yuan Shasha said.

Zhao Ke shook his head: "It's useless to say anything now. If your police's words are useful, then you can directly intervene in housing prices."

"I don't want to say anything? I just hope you can find Sun Yunmei as soon as possible. I'm almost being scolded by my wife. If the house can't be sold, the money will be lost."

"The house is not for speculation, it is for living. If you live by yourself, you don't have to worry about these things. Don't you buy a house just to live comfortably?"

It feels like Zhao Ke and his wife are deliberately looking for depression for themselves, and Lu Weiwei is telling the truth.

Zhao Ke nodded silently: "Although that's the case, but after this incident, I feel quite weird when I walk into the whole room again."

"I didn't feel very surprised before, but now every time I go to the living room, I can't help but think of the secret room that has been sealed by the wall for 3 years or longer."

"The hairs can't help but stand on end, don't worry about it, let me live here now, it's just suffering."

"Okay, I got it." Probably from Zhao Ke, I have a comprehensive understanding of the details of the communication between Sun Yunmei and him.

Gu Chen put away the notebook.

I feel like I can go to the secret room now.

So Gu Chen took off the strong flashlight from the equipment again, and walked to the door of the sealed room.

After tearing off the cordon, putting on gloves, foot covers, mask and headgear, Gu Chen walked in first.

"Junior Brother Gu." Lu Weiwei also stepped over the damaged wall and followed closely behind.

The two came to the depths of the secret room one after another.

Officer Wang and Yuan Shasha stood outside.

Gu Chen turned to look at Lu Weiwei, and said, "Senior Sister Lu, you go to the left side of the room to search, I'll go to the right side, this time you must be careful, don't miss any tiny clues."

"Understood." Knowing this room is the root of the problem.

Especially after everyone's discussion before, it was discovered that Sun Yumei's falling into the river seemed to be related to Master Wu of the North Ridge Temple.

It even has something to do with Xu Dewen, the contractor who built the wall.

Therefore, everyone focused their investigation on this secret room.

That's why Gu Chen asked for extra careful inspection, hoping to find some details that he hadn't noticed before.

Shining a bright flashlight on the desk, Gu Chen stood in front of him and looked down.

On the desk, all the items were still the same, except for the knives that were taken from the desk before, leaving a few marks, and nothing special was found.

Gu Chen came to the portrait of the deceased again, and was in a daze.

"The whole room, if it's really the room where Sun Yunmei's dead son lived, then this photo can best illustrate the problem."

"But at that time, the input of ID card information was not complete, and some people might not even have registered residence."

"It is indeed difficult to investigate Sun Yunmei's family situation like this, but does Sun Yunmei have no other relatives here? Why is there only her twin sister, Sun Haifang?"

"Besides, Sun Haifang is also a loner, which is very strange."

Seeing Gu Chen standing alone under the photo talking to himself, Lu Weiwei leaned over and asked, "What's wrong, Junior Brother Gu? Is there a problem?"

"Senior Sister Lu." Gu Chen turned to look at Lu Weiwei, and said, "How can we prove that the portrait hanging on the wall is Sun Yunmei's son?"

"Uh……"

Facing Gu Chen's question, Lu Weiwei hesitated for a moment, and said thoughtfully, "Maybe... his appearance? After all, looking at this photo, the man's appearance is indeed somewhat similar to the Sun Haifang we saw."

"A son usually looks like his mother, and Sun Haifang and Sun Yunmei are twins, so the man in the photo also looks similar to Sun Yunmei."

After a pause, Lu Weiwei said again: "Perhaps... this is one of the evidences?"

"Maybe." Gu Chen nodded silently, then found a wooden chair next to him, stood directly on the wooden chair, held the photo frame with both hands, and began to lift it up.

Gu Chen directly took off the photo frame hanging on the wall.

Bringing it in front of Lu Weiwei, Gu Chen blew the dust lightly, and said, "But just a photo can't explain anything."

"After all, does Sun Yunmei's son look like this? There is no way to talk about it now."

"Also, if this photo is real, then there must be a sense of age."

"Her Sun Yunmei is about the same age, so if her son lived to this day, he would be a middle-aged uncle, so there are at least a few decades of photos."

"So..." Lu Weiwei seemed to have guessed what Gu Chen meant.

Gu Chen nodded silently: "So, the authenticity of this photo needs to be verified."

Due to the light, Gu Chen couldn't tell the authenticity of the photo frame in the room, so he had to take it outside to verify.

So he temporarily handed over the photo frame to Yuan Shasha outside.

You know, when Gu Chen deduces that this series of things is related to the key people listed before, Gu Chen feels that it is necessary to verify Sun Haifang's words.

If everyone is hiding a certain truth, then if you conduct investigations based on lies, what you get will eventually be lies.

Therefore, Gu Chen is now doing the opposite, first denying the previous clues to investigate.

For example, is this room really the room where Sun Yunmei's son lived?This is still up for debate.

Another example, Sun Yunmei's son, does this character really exist?Gu Chen doesn't know yet, and needs to find out from multiple sources.

The most important thing is that Gu Chen is currently unable to determine Sun Yunmei's relatives.

It seems that it is difficult to be authoritative based on the words of a twin sister, Sun Haifang.

There seems to be an undercurrent surging behind this seemingly simple incident.

If Sun Yunmei hadn't disappeared from the video that night, maybe Gu Chen wouldn't have cared about it.

But now, the fact that Sun Yunmei might fall into the river made the whole thing weird.

If Sun Yunmei didn't hide some secrets, why did she commit suicide by jumping into the river?

Or, was there something else wrong with her death?These Gu Chen are still unknown for the time being.

After more than an hour of various searches, Gu Chen basically turned the room upside down, but still found nothing.

Looking up at Lu Weiwei who was still searching, Gu Chen asked, "Senior Sister Lu, how is your inspection going?"

"It has been checked several times, and there is no search value." Lu Weiwei felt that her waist could hardly straighten up.

In order to search for suspicious clues just now, Lu Weiwei bowed her waist and searched under the bed for a long time.

It would be okay if there was something to be discovered, but nothing was found.

Gu Chen nodded slightly, and reminded: "It's almost done, let's withdraw."

"Okay." Lu Weiwei waited for Gu Chen's words for a long time, and slapped her back directly, and then walked out of the weird room with Gu Chen's support.

Gu Chen then also jumped out.

Yuan Shasha, who was holding the photo frame, hurried forward and asked, "Senior Brother Gu, how is your inspection going?"

"Not found." Gu Chen said lightly.

Lu Weiwei was also dejected: "It's just a few places, no matter how much you search, it will be like this."

"Then what about this photo frame?" Police Officer Wang also pointed to the photo frame in Yuan Shasha's hand.

Gu Chen grinned: "It's nothing, take it to the technical department of the Municipal Bureau for an appraisal."

"Okay." Feeling that the room was almost searched, Police Officer Wang said helplessly, "So, should we evacuate?"

"Let's go." Without hesitation, Gu Chen led everyone to stick the seal again, and then walked out of the villa together, and pulled up the cordon of the villa gate again.

Afterwards, Gu Chen drove and took everyone to the technical department of the Municipal Bureau.

……

……

2:30pm.

There is still no news from the Blue Sky Rescue Team, but at this time, Gu Chen still brought the photo frame to the testing room of the technical department.

Liu Fayi and Gao Chuanfeng looked at the photo frame in Gu Chen's hand in bewilderment, not knowing whether to laugh or cry.

Liu Fayi also asked with a faint smile, "Gu Chen, what's the situation with this photo frame?"

"Can you help me identify the exact year?" Gu Chen said.

Liu Fayi pursed his lips and said with a smile: "We are not experts in antique appraisal, but..."

After thinking for a while, Liu Fayi said again: "However, let's do our best and leave this matter to Gao Chuanfeng."

"Leave it to me?" Hearing Liu's forensic doctor's remarks, Gao Chuanfeng suddenly said bitterly: "Master, you are not an expert in identifying antiques, and neither am I. Is it reliable to leave this matter to me?"

"Why is it unreliable? There are so many instruments and equipment in our testing room, you can try it." Liu Forensic Doctor was also not polite.

After all, this kind of blame has to be carried by the apprentice.

Gao Chuanfeng looked depressed, but he could only reluctantly accept it: "That's fine, I can only say, try it."

"After all, I'm pretty good at detecting dead bodies, but it's really difficult for me to determine the year of this photo frame."

"Stop complaining, I don't blame you if you can't detect it." Lu Weiwei also said with a smile.

Originally brought this old photo frame here, everyone didn't have much hope, but it is difficult to identify the exact year of this old object with the naked eye, so I want to rely on the technical department of the Municipal Bureau to think about whether there is anything special about this group of people way?

But now it seems that it is completely embarrassing others.

In fact, the result Gu Chen asked for was also very simple, that is, the photo frame and the characters in the photo should match Sun Yunmei's son.

It is specifically manifested in the year, as long as it can be matched, it means that this person really exists.

In addition, the photos also showed some signs of damage, so Gu Chen wanted Liu Forensic and Gao Chuanfeng to scan the photos without serious damage.

It is best to hand over this kind of dirty work to the technical department of the Municipal Bureau, so as to save yourself all kinds of troubles.

But when Gao Chuanfeng put on white gloves and was about to take over the dirty work, as soon as the clip on the back of the photo album was opened, a thin object fell directly to the ground.

"What?" Gu Chen frowned, and quickly squatted down to examine it carefully.

"It's... a leaf?" Lu Weiwei wore gloves to pick it up, but found that she couldn't pick it up anyway, and immediately complained: "Isn't this leaf too thin? Why is it as thin as a piece of paper?"

"Maybe it's made of copper?" Gu Chen also felt that this leaf was too weird. Its shape was almost the same as that of a maple leaf, but it was so thin that it fell on the ground and couldn't be picked up by hand.

"Let me do it." Doctor Liu fetched two long tweezers from the tool table.

Then the left and right hands opened the bow at the same time, and only then managed to hold the thin leaf, stood up and showed it in front of everyone.

With the help of the lights in the testing room, everyone immediately gathered around and observed carefully.

Lu Weiwei couldn't help feeling: "This should be the same as what Junior Brother Gu said, right? Maybe it's made of copper sheet? But the copper sheet can be made so thin? Isn't this craftsmanship too good?"

"No, it's not a copper sheet." Yuan Shasha stared at the leaf on Forensic Liu's tweezers, and couldn't help but sigh: "This may... be a gold leaf."

"Gold...golden leaves?" Hearing Yuan Shasha's words, Police Officer Wang moved his head closer and looked left and right, asking Forensic Doctor Liu to adjust the angle.
"But it's hard to judge, right? Judging by the color, it does look like it's made of copper, but it also looks like it's made of gold."

"Senior Brother Wang, believe me, it is definitely gold. The luster of this gold leaf is completely different from that of copper leaf. My family has..."

In the middle of speaking, Yuan Shasha suddenly paused for a moment, and then said: "My family has seen it when traveling outside, and it is definitely not wrong."

"Xiao Yuan still has a strong understanding of gold." Gu Chen also grinned, nodded and said:

"It might really be gold leaf, not copper leaf as I thought it would be."

"Really?" Lu Weiwei looked blankly, and looked at Gu Chen: "Then how do you tell the difference?"

"Because the gold color is bright and golden yellow, and the surface particle density is fine."

"Where copper is darker, reddish, with a rough finish."

Gu Chen took the tweezers from Liu Fayi's hand, held the leaf in front of him, observed it repeatedly, and then said:

"Also, the mass difference of the same volume, the density of gold is higher than that of copper, so the volume of gold of the same weight is smaller than that of copper."

"If you put it into a cup full of water, the quality of the displaced water is small, it is gold, otherwise it is copper."

"En." After hearing Gu Chen's remarks, Liu Fayi nodded slightly, agreeing:
"In terms of color, the color of gold is indeed bright and golden yellow. In fact, there are many ways to distinguish gold from fake. Just like what Gu Chen said just now, look at the color."

"The higher the purity of gold jewelry, the darker the color."

"And another way is to weigh the weight. Gold jewelry should feel like sinking in the hand, while fake gold jewelry feels light."

"There is also listening to the sound." Gu Chen also continued to add: "Real gold with a fineness of more than 99% will make a rattling sound when thrown on a hard ground. There is no sound and no elasticity."

"Fake or low-quality gold has a crisp sound without dullness. It usually makes a 'Dangdang' sound, and the sound has a lingering sound, and it beats violently after landing."

"I know another one." Seeing that Liu Fayi and Gu Chen both expressed their views on Jin Zi, Yuan Shasha also hurriedly said:
"What's more, if it's ordinary domestic gold jewelry, it's all refined and prepared according to international standards, and it will be stamped."

"For example, '24K' is marked with 'pure red' or 'pure gold', and 18K gold is marked with the words '18K'."

"That's right." Officer Wang nodded silently after hearing the words: "The gold jewelry I bought for my wife usually has these marks on it."

"If this leaf is made of gold, it should be there too?"

After the words fell, Gu Chen directly held the tweezers and turned the leaves front and back.

Except for some strange lines on it, there is no logo.

Police Officer Wang was a little embarrassed, and complained, "So, is there anything on it?"

"No, it doesn't mean it's not gold. There are other ways to prove it." Gu Chen paused, and after thinking about it for a few seconds, he said again:

"I remember, bend it with your hand, if it is soft, it is gold, put it in dilute acid, if there are bubbles, it is fake gold, and there are other methods such as burning it on fire."

"Because the color of copper and gold is almost the same, it is actually difficult to distinguish copper and gold with the naked eye."

"But pure gold is soft and has low hardness. It can make shallow marks with fingernails, and it can leave teeth marks with teeth."

"Gold ornaments with high fineness are softer than those with low fineness. The more copper they contain, the harder they are. The bending method can also test the hardness. Pure gold is soft and easy to bend. The lower the purity, the harder it is to bend."

"That's right." Forensic Doctor Liu took a deep breath and continued, "If you put it in dilute acid and bubbles come out, it's a fake, because the fakes are mostly mixed with zinc, which will react with the acid."

"It can also be burned on the fire. The so-called...real gold is not afraid of fire. Because fake gold contains copper, it will be oxidized into black copper oxide when it is baked by fire."

"After heating and putting it in the acetaldehyde solution, what turns red is brass, which is fake gold."

"Haha, there are so many ways?" Listening to Gu Chen and Liu Forensic's explanation here, Lu Weiwei also smiled lightly, and said:
"But the problem we have to solve now doesn't seem to be this leaf. Is it gold or copper?"

"Rather, is this photo real or fake?"

"Okay, leave this to me." Gao Chuanfeng felt the same way.

It's just that such a gold leaf suddenly fell out of the photo frame, which is really puzzling.

In order to find out if there is anything else in this photo frame?Gao Chuanfeng continued to fall down several times, and checked several times.

After confirming that there is no abnormality, the detection work on the photos in the photo frame began.

Gao Chuanfeng first placed the photo under strong light, scanned it into the computer with a scanning instrument, and then began to use a carving knife to cut off a small piece of the photo, and put it into the instrument for testing.

After all, testing the year is not my strong point, and I feel that Gu Chen has found the wrong person, and he should go to a treasure appraisal expert.

But after a series of tests, Gao Chuanfeng suddenly hesitated and froze on the spot.

"What's wrong?" Gu Chen, who was waiting for the result, hurried over to ask after seeing this.

"Gu Chen, the photo you brought may be fake." Gao Chuanfeng suddenly turned to look at Gu Chen and said.

"Forged? What's the reason?" Gu Chen was puzzled.

"There is a problem with the coloring of the photo." Gao Chuanfeng frowned, and said slowly:

"Generally, this kind of old photos are developed after filming."

"The coloring is divided into two types: watercolor and oil paint. They are all painted on the photos after they are developed and printed."

After a pause, Gao Chuanfeng said again: "Coloring is similar to painting. Oil paint is to use sweater needles of different thicknesses to wrap absorbent cotton, then dip in various colors of paint, and slowly knead the colors on the photo."

"Watercolor is to use a brush to color on the photo, and the clothing and skin color of the characters are all realistic."

"Because it is painted in the later stage, the color of the clothes can be selected by the customer. When taking pictures, I wear red clothes. If you don't like it, you can ask the coloring master to dye it yellow."

"After that, there was a faceting method of raising oil paint according to the light. The coloring technology became more and more sophisticated, and the images produced were richer and the colors were more vivid."

"So?" Gu Chen asked.

Gao Chuanfeng hesitated for a moment, and said slowly: "So, the watercolor looks transparent and smooth, the oil color is solid and has particles on the surface, and the color preservation time of the oil paint is longer than that of the watercolor."

"Watercolours need to be painted first, and then the blemishes are repaired, while oil paints, the photos are first repaired and then colored."

"Anyway, I remember that I had some contact with my master Liu Forensic Medicine in the past, and I also learned some professional things from some old masters in photo studios."

"That's right." After hearing Gao Chuanfeng's remarks, Liu Fayi also said lightly:
"This kind of oil paint is packed in a tube, which is the size of eye ointment now, and it is divided into 12 and 24 colors."

"Watercolor is the cost of binding, divided into 12 and 18 colors. At that time, the price of an oil-colored photo of the same size was 3 to 4 times that of a watercolor-colored photo, and the price of a watercolor-colored photo was 1.5 to 2 times that of a black-and-white photo."

"We have indeed studied these things before."

"So it's like this?" After learning about the situation, Gu Chen looked at the photo in front of him again, and couldn't help but wonder, "So this photo?"

"It was printed with a modern ink printer, but it has undergone some old-fashioned treatments, and may have used some techniques tried by some counterfeiting institutions."

"In short, this kind of craftsmanship would never have appeared in that era. This photo seems to be full of age, but it was actually made in recent years." Gao Chuanfeng also based on the current situation he has. Explain the situation to Gu Chen.

Hearing Gao Chuanfeng's remarks, everyone couldn't help being taken aback.

Do you think this photo is fake?
"But why did this Sun Yunmei fake this photo? Could it be that she wanted to hide something? So that everyone can believe that this is indeed a photo of her son back then?"

"Could it be that Sun Yunmei wants to restore the original picture of her son?" Yuan Shasha said.

Gu Chen shook his head: "It's not necessary, with the current photo restoration technology, even if the photos of her son, Sun Yunmei, were damaged back then, she can find some retouchers to restore the original photos with a computer."

"However, this photo uses some modern craftsmanship, but still makes it look like a heavy age, which feels completely unnecessary."

"What exactly does this Sun Yunmei want to do?" Lu Weiwei said not calmly now:
"Before I discovered the secret room of my old villa. After being discovered by the current owner, I immediately rushed to the Beiling Mountain to pay homage to my son, and even went to the Beiling Monastery to seek enlightenment from Master Wu."

"As a result, she left Beiling Monastery and went directly to her missing husband's old house. Then she fell into the river and disappeared. There has been no news of her until now."

After a pause, Lu Weiwei said again: "But now, we found this strange photo in the secret room. The key point is that there is a gold leaf hidden in the photo. Even the photo is a fake. What on earth is she trying to do?" ?”

After the voice fell, the scene suddenly fell silent for a few seconds.

Officer Wang thought thoughtfully, "Could it be that this person is not Sun Yunmei's son at all?"
