Liu Qiaoqiao was taken by a phone call to the interrogation room of the Furong police station, a separate room where she is now a victim turned suspect.

"Are you sure you put the diamond in the safe, Ms. Liu?" Officer Wang cupped his forehead, and lost his previous politeness.

For now, if Liu Qiaoqiao is lying, it is suspected of fraud, which is as serious as the driver's attempted theft.

"Why do you ask such a question, comrade policeman?" Liu Qiaoqiao was stunned: "I swear, I really put the diamond in the safe, this is absolute." ”

"But the driver said that no diamonds were found, and some of you must be lying, but I hope it's not you, Ms. Liu. ”

Officer Wang pressed the fire in his heart and said with a wry smile.

A case of 100 million yuan can suddenly become a fraud case.

Although the driver did participate in the theft, if it was true, as the driver said, he used an oxygen cutter to cut open the safe and found no diamonds, then the case becomes a bit complicated.

Either the 60-carat diamond does not exist, or Liu Qiaoqiao himself hid the diamond in an unknown place.

In either case, what is in front of Officer Wang has become a difficult problem, and if you want to continue to solve it, it will inevitably take more energy.

I thought I had eaten chicken, but it turned out that the chicken ran away, leaving only a piece of chicken feathers.

"You don't believe me?" Liu Qiaoqiao changed her face as if she was flipping through a book: "You don't believe me, so what should I call the police? You policemen are not capable of solving the case themselves, and now they suspect me as a victim, do you still have a little conscience?"

Officer Wang slapped the table: "How do you speak? Aren't we investigating now?"

"Then what did you investigate? In the end, you can't find anything, poor my husband left me a relic that is just gone, you say that we, the taxpayers, pay so much money every year to support you policemen, what's the use?"

Liu Qiaoqiao now began to make a noise, making Officer Wang, who was sitting opposite, feel like he was on pins and needles.

I thought I could pick up a cheap one and think that I could easily solve this case, but it turned out to be the opposite.

Officer Wang gritted his back teeth, but found that Gu Chen next to him was actually playing with his mobile phone? He was really playing with his mobile phone, and he was chatting with people in a group called "Rookie Trainee Police Home"?

Suddenly, I felt a second wave of damage, and my heart said that this guy was too unrigorous.

"Gu Chen, why don't you come?"

The guy who was blown up by Lu Weiwei in the office, then give him a difficult case, Officer Wang just wants to be quiet at the moment, and he is about to be killed by the woman in front of him.

Gu Chen put away his phone and showed a standard handsome smile.

For probationary police officers, every opportunity to handle cases should not be missed, especially when Senior Brother Wang relented himself, then there would be no such thing as taking the lead by himself.

"Actually, you're not lying. Gu Chen habitually turned his pen: "That sixty-carat diamond is indeed placed in the safe." ”

Hearing this, Officer Wang, who originally thought he was relieved, suddenly spewed out the wolfberry tea that had just been drunk in his mouth: "Gu Chen, what are you talking about?"

"I didn't ...... That's right. Liu Qiaoqiao was also stunned, slowed down for two seconds, and said: "But if you can't find the diamond, then I won't leave, I will stay at your police station until the diamond is found." ”

Liu Qiaoqiao was still talking, but Gu Chen threw a transparent forensic bag containing powder on the table and said, "Now, this is your diamond." ”

Liu Qiaoqiao was dumbfounded, and she couldn't keep up with Gu Chen's brain circuit at all.

The heart said that he really took the old lady as a nervous disorder?

The old lady is at least a fierce woman who has beaten the junior and hammered the female secretary, okay?

You can do whatever you want, right?

Liu Qiaoqiao was really angry at this time, squinted her eyes, and slapped the table heavily: "The old lady is not crazy yet, there is no need to have this kind of black humor with the old lady." ”

Officer Wang was also frightened, and said that this was still a recording.

This has to be known by a group of two people, and he has a brain-dead probationary policeman, so where will this face go?

When we meet again, do you have to bury your head in the crotch?

"Gu Chen, are you crazy? Officer Wang glared at Gu Chen frantically, then leaned closer, and said softly: "Didn't you see that Liu Qiaoqiao was going crazy?

The heart said that this joke is not funny at all, okay?

Gu Chen also ignored Officer Wang, and asked Liu Qiaoqiao directly: "Ms. Liu, I want to ask you, how much do you know about diamonds?"

"More than you anyway. Liu Qiaoqiao tilted her head, clasped her hands to her chest, and put on a fiery posture.

"Because of their rarity and high value, diamonds are often sought after by the world and coveted by thieves. ”

Gu Chen continued to hang the pen in his hand and turned it, and said:

"In addition to the color, purity and carat, there is another important point that affects the value of a diamond, and that is its turning, or cutting. ”

"At present, the world's largest gem-quality diamonds are the so-called 'Star of Africa' and 'Cullinan' diamonds, weighing 3,106 carats, which were later cut into more than 100 precious diamonds of various sizes, and I think this one in your house is one of them, right?"

Hearing this, Liu Qiaoqiao's mouth opened wider and wider, and she was stunned for a few seconds before she said: "That's right, the diamond left by my husband is indeed one of them, but what does this have to do with the bag of powder in your hand?"

"A stupid thief, who does not know the nature of diamonds, is simply a tyrannical thing. Gu Chen shook his head helplessly, stood up and brought the packet of powder to Liu Qiaoqiao.

"Do you know the nature of diamonds?" Gu Chen asked again.

"I don't know. Liu Qiaoqiao's head shook like a rattle.

"Diamond is the hardest material known in nature. Gu Chen clasped his hands on his chest and sat back in his position: "Diamonds are often used to make diamond drill bits to cut other materials, diamonds are extremely brittle, and they are easy to break when they are impacted. ”

Liu Qiaoqiao continued to nod, as if she understood: "But you said so much, I still don't understand, why do you say that this bag of powder is my diamond?"

"Yes, Gu Chen, since you know so much about diamonds, then you can talk about it. Officer Wang suddenly had a new opinion on Gu Chen.

Seeing that he was all in the chest, it seemed that he knew something, but he said that the powder was a diamond, which gave Officer Wang a little headache, and he didn't know what this kid was doing.

"Because the main ingredient of diamonds is carbon. Gu Chen smiled, and Nunu said: "In the air, the temperature it adapts to is 850~1000 °C, and above this temperature, the diamond will burn and turn into gas." ”

Hearing this, Liu Qiaoqiao was stunned: "You mean...... My sixty-carat diamond was burned to ashes? How is this possible, hehe, this must not be. ”

Liu Qiaoqiao was almost frightened and fainted, this was the first time she had heard such a statement.

Officer Wang asked pragmatically, "Gu Chen, you said that the dust in that bag is a diamond, so what's going on?"

Gu Chen smiled: "These are carbon elements That's right, the mysterious disappearance of diamonds is actually related to the oxygen cutting machine, under high-temperature operation, the diamonds in the safe, when they reach the ignition point, turn into a pile of ashes, so this driver will say that he didn't find diamonds, in fact, diamonds have been almost given by this idiot...... Eh, Ms. Liu, are you okay?"

Gu Chen wanted to continue, but Liu Qiaoqiao was like a statue, his eyes rolled upward, and he fainted directly.

"Kombat 120. ”

The interrogation room suddenly became a pot of porridge.

......
