When Haichuan woke up at noon the next day, he first saw Chen Li and the class leader as the class representative, but what made him wonder why there were police officers here, and next to the policeman was wearing a long white coat, with a blue logo on the white coat, and inside the logo was a pattern like a five-petal flower, as a teacher who had published a paper in the journal "Cell", he would not recognize this sign, which was the logo of the Chinese Academy of Sciences.

Haichuan looked around at the crowd, and finally his eyes fell on the two policemen.

"You still know me, don't you?"

"Officer Nie?" This person Haichuan had naturally seen it, he was a police officer from the Xining City Police Station, but what surprised him was how he appeared here.

He greeted Haichuan with a smile, and stretched out his hand to introduce the police officer next to him: "This is Officer Zhang." ”

"The fire is so big, the doctor has seen your injuries, and it's okay, it's really lucky. Is it convenient for Mr. Haichuan? Officer Nie was dark-skinned and spoke Mandarin with a slight accent from the Qinghai dialect.

Haichuan nodded, Officer Nie motioned for the others to go out, Chen Li glanced at Haichuan worriedly, when he sent him to the hospital, the principal and some teachers came to visit him, including Yang and Xiang, it was already noon the next day, only Chen Li asked for leave to stay with him, the two usually fight and quarrel, and at the critical moment, they realized that she was such a person with heavy feelings, and I felt warm in my heart when I thought of this.

Haichuan nodded, smiled at her, and signaled that it was okay.

Everyone went out, only the people from the Chinese Academy of Sciences did not leave, although Haichuan couldn't figure it out, it was difficult to say anything.

"We're here to ask about the theft of the Tibetan Plateau Natural History Museum. As he spoke, Officer Zhang next to him took out a pen and paper and began to make a note.

"The last time we asked you about the fossil theft, you saw any suspicious people, and you said you didn't see anything. ”

"Yes. Haichuan nodded.

"Look at this picture. ”

Haichuan's result picture, the picture is very blurry, obviously magnified several times, and he looked carefully before he found that there was something like sand on the ground.

"This is to find sand in the museum, at first after many comparisons of the soil quality in various regions, we could not match what kind of soil quality it is, so we sent it to the Geological Bureau of the Chinese Academy of Sciences to make a major discovery. He paused when he said this, his face solemn and a little happy, "This soil contains basalt with strong magnetism, and it is frozen all year round, and it is geologically called 'frozen soil'. ”

"I don't quite understand what you mean by telling me. ”

"Don't you wonder where this soil comes from?" Officer Nie asked rhetorically.

"It can't come from me. ”

"This soil comes from the Nalengrad Gorge, which is also often referred to as the Kunlun Mountain Death Valley, and the soil of the Death Valley is composed of a large amount of basalt, and it is covered by thick ice all year round, and only there is such soil. A middle-aged man in his forties standing on the side said in a very flat tone, "Let me introduce myself, I am Wang Zhongheng from the Institute of the Chinese Academy of Sciences." ”

"You said that you went to ride three months ago on the 317 Qinghai-Tibet line, and Death Valley is not far from the 317 Qinghai-Tibet line. Officer Nie said, his eyes locked on Haichuan, as if he was interrogating a prisoner.

"But I haven't been to Death Valley, Death Valley is called Death Valley, and no one who enters it can come out alive, even the local hunters dare not enter it, how can I joke with my own life?"

"Who can prove it?" Officer Nie said aggressively.

"Who can prove that I went?" Haichuan asked rhetorically.

"There was a brief time when the lights went out and the camera was just you next to the fossil collection. At that moment, at most, 6 seconds, in addition to you, the closest visitor to the exhibit is also 5 meters, even if he has time to run over, it is impossible to escape the surveillance when he escapes, because there is no time to let him leave the monitoring range, so only you are the most suspicious. ”

Haichuan was also puzzled, how did he steal the fossils from the booth in such a short period of time, and also have to break the glass, and then leave silently? Even he, who is closest to the fossil collection, is very difficult to do.

"Okay, even if I stole it, then what kind of tools did I use to break the glass, could it be that I did it with my bare hands? You have to believe that when I went through the security check, it was scanned, and I didn't have any metal on me. On the other hand, where did I hide the fossil after I stole it? Didn't you say that I was still in the frame after the monitor was ready, and I was injured and fainted at the time, how did I hide it in such a short time?"

"Maybe it's always on you! The fossil isn't big, and the police didn't notice you at the time, so you can easily get the fossil out. ”

"Even if I can steal the fossil under such harsh conditions, but what about my motive?" Haichuan glanced at him, "You should have done a background check on me when you came, I have no motive to steal at all, what do I want it for?"

Officer Nie was silent, this was something he had never figured out, not to mention anything else, just stealing fossils in such a short period of time was almost incomplete. Haichuan was suspicious, but through his background investigation, it was found that his father was a national first-class calligrapher, his family background was clean, he had excellent grades since he was a child, and he did not have any bad records, and besides, why did he go to steal a fossil? You must know how far Qinghai City is from Jianghai City, and he went to Qinghai to steal a fossil for no reason? There was no motive at all.

But even if someone else stole the fossils, then what motive did he have for committing the crime? Fossils have a high value in archaeology, but what was stolen is the fossil of the climbing perch, and many fossils of the climbing perch have been found in northern Tibet, and the fossils themselves are difficult to sell, the transaction value is not high, and the fossils of the climbing perch have been found more, so why not choose the cultural relics with higher value in the museum?

The strangest thing is to check the reason for the short-term power outage of the circuit on the day, and the result is that nothing can be found, it is not a short circuit, and it is not artificially closed the electric switch, because there is a surveillance camera at the main electric gate of the museum, and there is no such possibility as artificial.

So Haichuan is a certain suspicion, but it is not enough to detain and interrogate, so there is an interrogation of Officer Nie here, to see if you can see some flaws in Haichuan's answer and expression, unfortunately, Haichuan's expression does not seem to be deliberately pretended, and from his answer, he feels that his answer is not only no problem, but his strict answer and rhetorical questions are like reasoning guidance on the case, it is a pity that this kid does not go to be a policeman, but if this person is a criminal, it is so frightening.

"Well, I can't find any evidence from the conversation with you, but...... Just because you're not suspicious doesn't mean you're not suspicious. ”

"So Officer Nie came all the way here to test me? ”

Officer Nie pretended to be angry, with an expression of "no national people's police".

In fact, Haichuan was also very puzzled, logically speaking, even if Officer Nie wanted to find any flaws and clues from his records, there was no need to invite someone from the Chinese Academy of Sciences to come, presumably for something else.

Seeing Haichuan's eyes locked on him, he was also surprised, thinking that it was possible that he knew what I was going to ask him, this young man was really peculiar, and his mature psychological quality and observation ability were really higher than ordinary people.

"Do you know about a few explosions on Haidian Island recently?" he looked at Haichuan, as if expecting his reaction.

"Could it be that these explosions have anything to do with the theft of fossils from the Qinghai-Tibet Museum?"

"I don't know if it has anything to do with it, but we found a substance at the site of the explosion, and that is the permafrost soil of Death Valley. In the 90s of the 20th century, the scientific expedition team of the Xinjiang Geological Bureau entered the canyon to investigate in order to unravel the secrets of Death Valley. ”

He paused for a while, looked at Officer Nie and them, and seemed to hesitate: "The 'frozen soil' brought out from it is only one of us studying, it is different from other 'frozen soil', the atomic structure in it is beyond our understanding, as if there is a new chemical element in it!"

"You are appearing in the Qinghai Museum, and it happens that there is also 'frozen soil' in it, and you come back to Jianghai City, but it appears again, don't you think it's strange?"

Even he felt that he was very suspicious of this, but after careful analysis, there were many things that did not make sense.

"I don't think you forgot or omitted any details that you didn't tell us?"

Haichuan recalled that he rode on the Sichuan-Tibet line, and then went to the Qinghai Museum, thinking about the more headaches he had.

"If you find any problems, please contact me as soon as possible, this is my number. Officer Nie wrote down the phone, "Then we won't disturb your rest for now." ”

After saying that, he and Professor Wang Zhongheng left.

Not long after they left, Chen Li walked in, cut the peeled apple into pieces, first put a piece in his mouth, and then sent a piece to Haichuan.

"What are they looking for from you? She asked casually.

"I came here for the previous fossil theft case at the Qinghai-Tibet Plateau Museum. ”

"Oh, what useful clues did they get from you?"

"No, and I'm sorry about that. ”

"Then can you feel better eating an apple?" Chen Li looked at Haichuan and smiled brightly.

Haichuan nodded, "Of course."

Chen Li accompanied Haichuan for a while, and the doctor said that he was fine, and he would go back to school first if there was still class in the afternoon.

Haichuan looked at Chen Li's back, his expression became deep, from the chat with Chen Li, he always felt that Chen Li was a little strange, as if for her, the police and the people from the Chinese Academy of Sciences looking for him did not arouse her curiosity at all.

Haichuan looked at his body carefully, he remembered that his arms and shoulders were burned by fire, but now he didn't see the slightest scar, although he didn't feel that pain at the moment, he always felt as if there was something hidden in his body, and this strange thought lingered in his mind like obsessive-compulsive disorder.

All the changes came from what happened three months ago after he came back from riding the Sichuan-Tibet line, which made his body change like this?
