Chapter 35 Section 6

After knocking on the door, a cold "please come in" came out.Kaoru said "Excuse me" and opened the door.But she didn't enter the room immediately because it was pitch dark. "Sorry, can I trouble you to close the door quickly? Once the light leaks, it will be difficult to observe." Tang Chuan's voice sounded from the back. "Ah, I'm sorry." Kaoru said as she closed the door, and walked slowly while looking at the road ahead. Yu Chuan was standing next to the workbench in a white coat, and a white object appeared on the workbench.These objects are not placed on the workbench, but actually floating in the air, and they also emit light.It's a bunch of white dots.

Yu Chuan seemed to operate the device, and then the objects floating in the air began to change shape.It wasn't long before they formed something Kaoru had known.Kaoru couldn't help but let out an "ah". "What do you look like?" Tang Chuan asked. Kaoru swallowed, and said, "The school badge is like the school badge of Imperial University." "Okay, since even you, who didn't know anything beforehand, feel like you, then there's no problem." Then Yu Chuan pressed the switch of the device a few more times, and the characters floating in the air turned into two circles, overlapping each other.

"What the hell is going on? How could this thing float in mid-air?" "Instead of floating in the air, it is more appropriate to say that graphics and text are arranged in space. Isn't air made of oxygen and nitrogen? I use laser light to charge these molecules, and then use high-performance pulses Lasers make them produce nearly a thousand light spots in one second, and then you just need to arrange them into the combination you want." Kaoru stared blankly at the figure in the sky with her mouth half open.Although she didn't understand Tang Chuan's explanation, she still understood the advanced nature of this technology.

"The previous impact technology required a display or fluorescent screen to carry the picture, but this method no longer needs those things. This technology can draw images in any space. Maybe it will be applied to stereoscopic TV in the future .” "What an amazing invention." "Unfortunately, this is not my invention. Our laboratory is just trying to reproduce this technology that is currently gradually taking shape." "Teacher, do you also imitate others?" "Don't underestimate imitation. First imitate, and then take your own step from imitation. This is the theory of research." Tang Chuan cut off the power of the device and pressed the switch on the wall, "Okay , let’s hear what you have to say next. I remember it’s related to prospecting, right?”

"Yes. Sorry to bother you in your busy schedule." "It's nothing. To be honest, I'm also a little interested in this matter. All in all, I'd better make some coffee first." Tang Chuan said as he took off his white coat and walked to the pool. After sitting on the chair and taking a sip of instant coffee, Yukawa let out a long sigh of relief.Then he shook his head left and right, as if to relieve the sore shoulder, and then adjusted his glasses with his free hand: "That is to say, the junior high school girl hopes to find a way to clear her mother of suspicion, So she thought of finding the missing dog. She thought that as long as she found the dog, she could find out who the real culprit was."

Xun nodded: "Because the disappearance of the dog is a big mystery in this case, so it is understandable for her to think this way, but I didn't expect that she actually found it..." "You said you used a pendant? How did you do it?" "Like I told you on the phone, it's a chain with a crystal on it. She picks up the chain with her fingers and asks the question. Where should I go to find the dog? Left or right Right, or south or north? That's it. The pendant will answer her yes or no." "You said you saw her do that too?" "I see. Every time I come to a fork in the road, she will squat down and do something, but I never even dreamed that she was asking Zhuizi for advice."

Yu Chuan put the mug on the workbench and said: "This is indeed prospecting. Usually, two metal rods bent into an L shape called 'prospecting rods' are used, but I have also heard of using a pendulum." method." Kaoru tilted his head in confusion and asked: "Then how can this be explained scientifically? I checked it online before, but I still don't quite understand it. It is really useful when digging a well, right? I think so too. The article called it 'pseudoscience', but then saw some reports that a water company used prospecting to find abandoned dilapidated water pipes."

Tang Chuan said with a wry smile: "Because prospecting is the same as other superpowers, and it is an irrefutable question." "What's the meaning?" "Scientists have never stopped conducting experiments on prospecting technology since ancient times. It is not surprising that after entering the 21st century, some people have also done experiments in this area. From the conclusion, it has never been confirmed I have given an example of the effect of prospecting. Although they are all simple experiments such as finding buried objects in the ground or finding one with something in several boxes, they have never left results other than chance. In short In short, the result is not much different from wild guessing without prospecting."

"So, in the final analysis, it is a kind of tricky thing." "—It is impossible to say for sure, which is the difficulty of this kind of problem. You can't completely deny the prospecting technique just because it can't show an effective difference in a specific experiment. Because it may be that the experimental method is wrong, and at the same time, the prospector's own ability is insufficient or simply The possibility of a liar. And this is the so-called irrefutable." "Judging from what you just said, Mr. Tang Chuan, you personally don't believe it, do you?"

Hearing Kaoru's words, the physicist frowned unhappily: "'I don't believe it' is quite surprising. Personally, as long as the experiment is done under fair conditions, As a result, no matter how unbelievable it is, I am ready to believe it. But since there is no such result at present, I cannot comment on it.” "Then what do you think of this case? Hazuki Mase did indeed discover the dog's body using prospecting techniques." Tang Chuan stared at Kaoru's face and said, "What do you think? Do you believe what the girl said?" "Well... I haven't figured it out yet, and I don't know whether I should believe it. After all, I saw it with my own eyes, so I really hope it is true, but at the same time I have some doubts: Is this really possible? ?”

"Has the discovery of the dog's body affected the investigation?" "Several... No, it should be said that it has brought a lot of influence." The dog's body was examined, and toxic substances were detected from its body.It's a pesticide that seems to be in dog food. "The poison was found in the body. If this is the case, it is inseparable from the murder case. A more reasonable idea should be that the poisoned dog and the person who disposed of the dog's corpse were the murderers of the old lady. How much does the dog weigh? ?” "About twelve kilograms." "I remember you said that the stolen gold weighed 10 kilograms, right? It adds up to a total of 22 kilograms. If you want an ordinary woman to carry it, you probably need a cart." "You're right. And even if you can hide ten kilograms of gold in a bag and take it away, a twenty-two-kilogram Kai dog won't fit in the bag. It's more reasonable to think that the murderer drove a car." "Does that insurance woman have a car?" "No. We also went to the car rental company to inquire, but we haven't found any record of her ever renting a car." "So that's it. It seems that you are really devastated by the discovery of the dog's corpse." Tang Chuan said with a smile, "Speaking of which, why did the murderer hide the dog's corpse?" "That's not clear. All I can think of right now is the possibility of detecting poison from the dog's carcass..." "You mean, the murderer is afraid of leaving physical evidence? If that's the case, wouldn't it be fine if he didn't use any poison from the beginning?" Tang Chuan muttered to himself, turned to look at Xun and asked , "Let me ask you, that girl found such important evidence, how do the police plan to treat her confession?" "The jury is still out and the bosses are worrying about it. The suspect's daughter found the dog's body with prospecting - they can't just put it in the report." Tang Chuan shook his body lightly, and said, "Among the bosses you mentioned, I'm afraid Kusanagi was included, right? That's why you came here to ask me for advice?" "Since you know it well, can I trouble you to help solve this mystery?" "Not all of your bosses are incompetent. Doesn't anyone plan to logically reason about why the girl was able to find the dog's corpse?" "Of course there is. For example, our section chief, he guessed that the girl probably knew where the dog's body was. That is to say, the girl herself has some form of connection with this case." "Yes, it is indeed logical." "But if that's the case, then she doesn't need to move out the prospecting. She just needs to write an anonymous letter to the police and tell us where the dog's body is. In fact, she herself said that if That's what she's going to do if she finds the dog. And I've said it many times, and I witnessed her discovering the dog the whole time." Kaoru's emphatic tone caused Yukawa to remain silent with a serious expression on his face.Kaoru looked directly at him and continued: "Let me add one more thing. Mase Hazuki's classmates also know that she can use prospecting. It is said that although she rarely uses it in front of others, several people have seen it with their own eyes, and Still very effective." Kaoru went to the junior high school where Mase Hazuki attended and asked a few students about it.Of course she didn't say that it was related to the investigation of the murder case, but she still told them the truth about her identity as a policeman, and every student answered her questions seriously. Tang Chuan, who crossed his arms and looked down at the ground, raised his head: "Can I meet that girl? If possible, I hope to meet her in this laboratory." "Okay, I'll make arrangements." Kaoru nodded.She was just waiting for Tang Chuan to say this.
