"Is that ......," Su Ping replied, and then tried to lift the safe.

"Huh?"

The safe was particularly heavy, and it took him a lot of effort. But when he lifted it, he was a little surprised to find that several keys were pressed under the safe.

Removing the key, he frowned slightly, and tried to insert it into the lock hole of the safe.

With a slight twist, it turned on.

He was even more surprised, and then immediately took out the safe and took several pictures in quick succession.

The contents were fine, all cash, gold bars and the like, and there didn't seem to be any contraband.

But......

A full thirty one-kilogram gold bars is a problem in itself.

According to the recent gold price in the bank account, each gram of gold fluctuated between 295 yuan and 300 yuan during this time, and even if the lowest price is taken, the gold here is worth a full 8.85 million.

It would be even more exaggerated if the price given by the gold deferred delivery business of the gold exchange was above 360 yuan per gram. Of course, it is basically impossible to achieve this price goal for physical gold recycling.

"This Xiang Haichuan, where did you get so much gold?" Su Ping was a little puzzled.

The landlord standing on the side had a sudden look in his eyes, although Su Ping did not take out the gold, he could still see a corner of it from his angle, and his eyes were straight.

The landlord owns such a whole residential building, and there are still tens of millions of real estate. It's just that it's a completely different concept, dozens of gold bars, or a large stack of banknotes, the visual impact is quite strong, because it is difficult for the human brain to accurately estimate its value in a short period of time, either over-under-estimated or over-valued.

The landlord apparently overestimated the value of the thirty gold bars.

Qi Yuan came out of the kitchen, saw the situation in the safe, and was almost blinded.

But soon, Su Ping sighed, reached out and took out a gold bar from the cabinet, and found that although the gold bar was printed with the words AU pure gold 999 and 1000g, its gold was relatively dull, and the volume seemed to be much larger.

He squinted, compared the length, width and height of the gold bar, shook his head and said, "It's not gold, it's copper, but compared to ordinary brass, it may have added some other elements, and it looks closer to gold." ”

"Huh?" Qi Yuan hurriedly walked over, looked at it a few times, and then asked thoughtfully, "Is it because the density is too different?" ”

"Hmm." Su Ping bowed his head lightly and said: "The density of gold reaches more than nineteen grams per cubic centimeter, and the brass does not remember very clearly, because the alloy fluctuates, but it should not exceed nine grams per cubic decimeter, and the difference between the two is too much."

If it is made into gold jewelry and the weight is not marked, it is not possible to guess that these metal bars are not gold bars based on this speculation.

After all, the volume of jewelry is not accurate, the gold density is too high, the unit price is too high, and the ductility itself is excellent, so many manufacturers will make the jewelry hollow to a certain extent in order to look more comfortable visually.

But it turned into gold bars...... Hehe. Gold bars are basically investment gold, unless it is a one-gram five-gram gold bar, there is no need to make it hollow.

I've seen a kilogram of gold bars, much smaller than it, and I've just roughly calculated its volume and density...... Hawkers,In order to facilitate the calculation, I basically take the whole number.,Calculate that its density does not exceed ten grams per cubic centimeter.,Obviously, it won't be gold.,18K gold isn't.,The density doesn't match.。 ”

Qi Yuan walked over and squatted down, looked at it a few times, and then asked, "Then, what is he hoarding so much fake gold for?" Are you planning to deceive others, or have you been deceived? ”

"I'm afraid I was deceived." Su Ping said softly: "If you plan to deceive others, there is no need to lock this thing in the safe, because he knows very well that copper is not worth much in these years, thirty kilograms, it won't cost much." ”

The landlord had been listening with his ears pricked up, and when he heard this, he couldn't help but pat his chest lightly, let out two long breaths, and his heartbeat slowly calmed down.

Su Ping glanced at him.

The landlord felt Su Ping's gaze, coughed dryly, and asked, "That's ...... Is there anything else you'd like to ask, comrade policeman? ”

"How much do you know about this household?"

"Uh, didn't you just say this, don't you know too much......"

"That's fine." Su Ping shook his head slightly.

The landlord opened his mouth, coughed twice, and said, "Ah, by the way, my family is still making soup, so I'll go back first." If anything, feel free to call me. ”

"Okay, I'm sorry for you, leave a contact information, I'll call you." Su Ping said, and then continued: "My number is troublesome for you to save it, and if you think of or find any clues, you can also tell us at any time." ”

"Okay." The landlord nodded, and felt that it was unlikely that Su Ping and them were fighting in such a big battle just to check the deck or something, so he couldn't help but ask: "That, comrade policeman, this person, can't he be killed and escaped?" ”

Su Ping smiled and shook his head.

The landlord hesitated for a while, and saw that there was really no excuse to stay, so he exchanged phone numbers with Su Ping and turned to leave.

Seeing him leave, Su Ping retracted his gaze, squinted and said, "Xiao Qi, search it, search it inside and out, don't let go of any corner." ”

"Okay." Qi Yuan bowed his head and ran to the kitchen again.

Su Ping raised his eyebrows: "No, what are you doing in the kitchen when you are old?" Hungry and want something to eat? ”

"Uh......" Qi Yuan paused slightly, and explained: "I wondered if the murder weapon could be a kitchen knife or something, after all, this kind of murder weapon is the most common......"

"You ghost knife!" Su Ping rolled his eyes: "You didn't watch the murder video?" Cutting off Cao Mingyang's hand refers to the gardening scissors, aiming at the joints, clicking on it, and the fingers come down.

What cut off Chu Xunliang's head was a thick-backed machete, thirty centimeters long, and his back was half a centimeter wide.

The video was shot clearly, and the murderer had no intention of concealing it, so you can tell me now that the murder weapon could be a kitchen knife? ”

Qi Yuan was stunned, quickly came back to his senses, and said, "I'm sorry, I remembered wrong...... Then I'll go to the toilet and see if there's any blood......"

"The blood stains have also been washed off, and you don't have the luminol reagent on you, what do you see?" Su Ping stretched out his hand and pointed to the bedroom, and said, "Don't mess with me to do anything about it, go to the bedroom and take a look......"

Before Su Ping finished speaking, Qi Yuan silently took out a bottle of watering can in a sealed bag from his pocket and whispered, "I think it may be useful, so Director Guan Wei asked for a bottle......

The lighting conditions in the bathroom are quite poor, and it is not early at this time, if there is blood, you should be able to see the fluorescence reaction more clearly......"

This time it was Su Ping's turn to stay stunned......
