I believe that anyone who has studied physics knows the famous Newton's law of gravity, that is, the earth has an attraction, and any object has gravity, and the heavier the object, the greater the attraction to the earth's interior.

Just like the blue and white porcelain that is subjected to gravity, it retains a position for a long time, and the bottom of the cabinet silently records the traces of its existence.

"The blue and white porcelain has been touched."

Link immediately realized the meaning of Jiang Hao's words, and recalled that just now, Jiang Hao did take the blue and white porcelain from the door near the safe, and the traces of the blue and white porcelain were in the innermost part of the cabinet, and the answer was about to come out.

"It was touched by robbers."

Jiang Hao continued to play with the blue and white porcelain, and sniffed a few times on the blue and white porcelain without a trace, verifying the judgment of the odor investigation method.

"Li Mazi is a robber, the cabinets have been pried open, he naturally wants to take a look at the things in it, what's so strange about this."

Zhang Lang pursed his lips disapprenosantly, if this can also be regarded as a clue to solve the case, all kinds of items that were discarded indiscriminately on the ground are also clues to solve the case.

"Zhang Lang is right, open it and look at it, it is indeed *normal."

Fang Meng agrees with Zhang Lang's point of view, if the robbers don't rummage around, how can they know the value of the item? This is completely in line with common sense, it is indeed not a clue, but she has a strong hunch, Jiang Hao said that blue and white porcelain is a clue, it must be not so simple, because what Jiang Hao said seems to be very accurate, this is beyond doubt.

Link also nodded in agreement, the blue and white porcelain was moved, which could only prove that Li Mazi had touched the porcelain, and nothing else could prove it.

"Look at the porcelain on the ground"

Jiang Hao was not in a hurry to explain, but changed the topic, his eyes swept to the messy ground, there was indeed porcelain on the ground, but none of the porcelain was intact, and there was even a fine wine jug, which was smashed to pieces.

"It's all bad, what does that mean?"

Zhang Lang's questioning was supported by Fang Meng and Link Ke, which made his waist straighter, and picking thorns was what he was best at, and he immediately asked Jiang Hao.

"Do you think all this porcelain was originally broken?"

Jiang Hao glanced at Zhang Lang with disdain, shook the intact porcelain in his hand, and said in an emphatic tone: "This is the only piece of porcelain that is intact among all the open safes, and it is still completely placed in the safe." ”

Zhang Lang admired Jiang Hao's imagination very much, but he really couldn't understand the meaning of Jiang Hao's words, and said lazily: "This doesn't seem to be able to show anything, it can only show that Li Mazi used porcelain when he robbed the *robbery, and then put it back from the new one, that's all." ”

"That's all?" Jiang Hao was amused by Zhang Lang's words, and simply asked, "If you were a robber, would you take the things out and then put them back in their original places?" ”

"This?" Zhang Lang was speechless, judging from the messy environment of the scene, Li Mazi did still have the items on the ground, but why did he put the blue and white porcelain back in the safe? Shrugged helplessly: "How can the robber's thoughts be understood by normal people?" ”

"Isn't it true that the police are going to investigate every suspicious point, such a big suspicion, do you take it for granted?"

Jiang Hao did not hide the irony in his tone at all, he was too lazy to talk to Zhang Lang, and no matter how much he explained to Zhang Lang, it was a pure waste of words.

"It's really hard to judge based on the clues you have."

Link thought for a while, Jiang Hao's question was indeed a big suspicion, from the explosion to the robbery in the safe storage room, Li Mazi and his gang, who were in a hurry, would definitely not put the blue and white porcelain taken out of the safe into it, because they knew better than anyone the preciousness of time, but the behavior of the criminals was sometimes so inscrutable.

For example, some time ago, a thief broke into someone's house, did not steal a dime, but left a note to the owner of the house, strongly despised the owner of the house, what should be the explanation for this behavior?

"Only by observing the details can you find more clues, and what you will think about is still to come." Jiang Hao looked directly at Zhang Lang and said in a calm tone: "If I say that Li Mazi left something in this safe, do you believe it?" ”

"You're really kidding."

Zhang Lang glanced at the empty safe with confirmation, the cabinet was clean and there was not even a single hair, let alone any leftovers, Jiang Hao, I please, are your eyes blind?

"Nothing!"

Fang Meng flashed her beautiful eyes, Jiang Hao's words were completely groundless, could it be that Jiang Hao was talking angrily?

"Brother Jiang Hao, don't sell it."

Link smiled bitterly and patted Jiang Hao's shoulder, urging: "What the hell is it, you just say it directly." ”

"That's it!"

Jiang Hao really couldn't figure it out, he was holding such a big blue and white porcelain in his hand, why couldn't the three of them notice it, so he simply put the blue and white porcelain from the new into the cabinet.

"What?"

The three of them were thundered by Jiang Hao's actions, and they were so depressed that they almost vomited blood, and they had been doing it for a long time, and the blue and white porcelain was left by Li Mazi and his gang.

Robbed * robbed the safe, but left blue and white porcelain in the safe, does anyone believe this?

"The blue and white porcelain looks like a few million, isn't Li Mazi here to rob, but to deposit?"

Fang Meng was amused by Jiang Hao's cold joke, and giggled, Li Mazi had no reason or reason, he wanted to put a piece of blue and white porcelain in the safe, the behavior of the criminals was incomprehensible, but this was also unthinkable.

"Just because I don't know the way doesn't mean he doesn't exist, that's the way it is."

Jiang Hao knew that even he didn't believe it, but this was indeed the result of the judgment of the tracing technique, and his appreciation technique had never made a mistake, which was enough to prove the credibility of the tracing technique, and he also successfully found out the evidence that the blue and white porcelain was brought by Li Mazi.

"Is that the truth?" Zhang Lang squinted at Jiang Hao and asked directly, "What about the evidence?" ”

Fang Meng and Link also looked at Jiang Hao at the same time, facts are greater than words, evidence is the best explanation, and they all expect Jiang Hao to come up with strong evidence.

"It's too easy to get proof." Jiang Hao directly threw the porcelain to Link: "Smell it with your nose, and you will understand." ”

Lin Ke took the porcelain suspiciously, leaned on the porcelain and sniffed it fiercely, and handed it to Zhang Lang, who was eager to try, with a slight frown, and did not speak.

"It smells like gunpowder."

Zhang Lang sniffed casually a few times, frowned, exhaled fiercely, and handed it to Fang Meng in disgust.

"There is the smell of explosives, but it should be left over from Li Mazi when he took the porcelain, as for the other smells, it seems to be gone."

Fang Meng's little nose sniffed hard, and confirmed it several times before he carefully said the result of the sniffing, and looked at Jiang Hao for verification.

"Smell these again."

Jiang Hao casually bent down and picked up a few discarded objects on the ground and handed them directly to Fang Meng, he believed that as long as he made a simple comparison, everything would be naturally clear.

"This one has a peculiar smell of paint."

Fang Meng took the object that Jiang Hao picked up casually, sniffed it carefully, and found that each item had more or less the same smell of paint.

"How can there be the same smell of paint?"

Zhang Lang sniffed the objects he picked up on the spot in disbelief, although the smell of paint on the items was strong and faint, but there was no doubt that there was a smell on each piece.

"I know this."

Qian Guoxing, who was responsible for cooperating with the investigation, explained: "Our batch of safes are specially customized, and for the sake of the beauty of the safes, after the production is completed, they are painted inside and out, and it is normal for them to smell paint."

Especially for items that have been stored for a long time, the smell of paint is even stronger. ”

The reason why Qian Guoxing knows so much is because many people who handle storage business have complained about this problem, and he naturally remembers it very clearly.

Link also picked up a few items suspiciously, put them on his nose and sniffed them, and immediately understood Jiang Hao's true intentions, and said incredibly: "There is no smell of paint on the blue and white porcelain, could it be that the blue and white porcelain was put in later." ”

"Is it because the deposit time is too short?"

Fang Meng couldn't accept the statement that the robbers would put porcelain in the safe for a while, and raised the question in his heart.

"This has to be explained by President Qian."

Jiang Hao looked at Qian Guoxing with a smile, waiting for his reply.

"The safe of 1162 has not been opened for a long time." Qian Guoxing said affirmatively.

"How can you be sure of so many cabinets?"

Zhang Lang glanced at the neatly arranged, no less than hundreds of safes, if you really want to record it clearly, I'm afraid it's not a simple matter.

"To tell you the truth, the house number of my house is 1162, and I wanted to buy this safe to store items, but it was purchased in advance, maybe because of the same house number as my house, and I inadvertently paid special attention to 1162."

Qian Guoxing explained in detail: "I haven't seen it open for at least half a year. ”

"There are traces of porcelain in the cabinet, which proves that there is indeed a porcelain here, if you are not mistaken, maybe the two porcelain are exactly the same, because this porcelain is fake."

Jiang Hao told Link about the results of the appreciation.

After getting Qian Guoxing's confirmation and Jiang Hao's appreciation, Link Ke could conclude without thinking about it that the porcelain had been replaced, and he frowned very curiously: "This Li Mazi, what the hell do you want to do." ”

"The means of stealing beams and changing pillars and concealing the sky and the sea are very clever, as for his real purpose, it is unknown."

Jiang Hao sighed helplessly, the smell investigation method of the tracing technique, and the clue given to solve the case, is that the porcelain does not belong to the safe space, and there is nothing else.

"Robbing * robbers do not rob * robbery, but do the matter of exchanging porcelain, it is really incomprehensible."

Fang Meng exhaled in disbelief, if she hadn't seen it with her own eyes, she would have really found it difficult to accept that Li Mazi had made such a big move in order to exchange porcelain.

Inside the safe, there was silence.

Jingle bells

Link's mobile phone rang suddenly, breaking the pensing crowd, Link quickly picked up the mobile phone and pressed the answer button, listened to it for a while and hung up the phone, and said helplessly: "Li Mazi's car was found, but the person ran away." ”

"Can I go and see?"

Jiang Hao was reluctant to let go of such a good opportunity to improve his proficiency in tracing techniques, he keenly felt that the blue and white porcelain in the safe must be hiding some secrets, and as for what secrets they were, they had to solve them by themselves.

Revealing secrets is Jiang Hao's favorite thing to do.

"Okay."

Link appreciates Jiang Hao's judgment very much, he still needs to continue to investigate the situation of the cabinet, let Jiang Hao go to the scene to investigate, maybe he can find out what clues have been missed, after all, this Jiang Hao is really good at it.
