Return to 1983 and be a detective

Niu Yonggui naturally knew what Xu Shan meant.

He glanced at Lu Bufan and saw that Lu Bufan had no vision at all and was looking at Xu Shan with hostility, so he slapped him with his arm to make him look away.

After that, he said: "A task force has been set up and experts have been invited from above, but nothing has been achieved. Moreover, this case has had a great impact. So many people have died. It is difficult to complete the work of appeasing them. If we arrest Unless the real culprit is found, we don’t know how to deal with it.”

"So you want to ask me to take a look at it for you? I'm the one who said the dirty talk first. I'd be happy to take a look, but I'm far from the big guys in our department. I mean, if I'm lucky, I can meet a few of them. This case only brought a little fame. Don't bet your money on me."

This is not Xu Shan’s modesty.

As a person, you must know your position and how much you weigh.

Especially for this kind of case that does not exist in Xu Shan's memory, the possibility of Xu Shan overturning is still very high.

Niu Yonggui said quickly: "Of course. We asked Comrade Xu Shan to solve the case together. We also want to change our minds and see if your new ideas for solving the case can provide us with some new directions for solving the case."

Xu Shan got the promise and felt relieved. He picked up a piece of snow-coated bean paste and put it in his mouth to bite. The outer layer of snow-coated bean paste was juicy. The bean paste filling inside was very fragrant and soft, but not particularly sweet. It has a rose scent and is really delicious.

He narrowed his eyes in enjoyment, and then asked casually: "By the way, what happened to those animals in the end?"

"The circus encountered such a big incident. The animals were all sent to the zoo. It's just that after entering the zoo, the animals seemed to miss their trainers. They didn't even eat or drink. In the end, they went on a hunger strike and died."

"Oh? Is there such a thing? It seems that this animal is more emotional than humans."

Xu Shan seemed to just say it casually, but in fact, Xu Shan didn't think animals could be so loyal.If it is possible that animals like black bears are really very emotional, then isn't there also a tiger?

Tigers are big cats. Many studies on cat behavior in later generations have shown that cats and dogs actually treat their owners very differently. Dogs regard their owners as gods, but cats view their owners as slaves.

This is the difference between a cat slave and a shit shovel.

As for the animal trainers of this kind of circus, to put it bluntly, they just understand some of Pavlov's tricks. They seem to lack a lot to establish real relationships with these beasts.

Of course, these are just his guesses, and they are not particularly important to solving the case.

He asked again: "Have you checked the trapeze stand afterwards? Have you figured out why the actor's head suddenly disappeared?"

Niu Yonggui shook his head: "This is what's particularly weird about that performance. When performing a trapeze on a shelf, you have to circle around the center at high speed. Only when the centripetal force and centrifugal force are enough, the person will rise, so that The actor had been spinning around in circles before, but why did he suddenly stop spinning his head?"

"There's not a second person on the shelf, is there?"

"No, generally this kind of performance involves one person first, then the second person, and finally the third person. They perform one person's movements, two people's movements, and three people's movements from easy to difficult in the air. Everyone is on the shelf. Flying, jumping, somersaulting, etc..."

What came to Xu Shan's mind was the first episode of Detective Conan, the roller coaster murder case, the case of killing people with the string of a necklace.If a tough thin line is stretched on the frame in advance, and when the actor spins in a circle at high speed and the speed is sufficient, the neck touches the thin line, the thin line may cut off the person's neck due to inertia.

But this doesn't explain why the actor has been rotating at high speed without touching the line.

Bao Laohei grew up in a discussion environment like Criminal Investigation Xinba, and his thinking is relatively scattered: "Is it possible to hang a wire on this shelf, and then cut off the head when it touches it? It is a reasonable speculation."

Lu Bufan immediately shook his head when he heard this: "Impossible, do you think we can't think of this assumption of yours? In fact, the part that leads the actor in circles is movable and is an axle, and other places have no conditions for hanging wires. , even if the iron wire is hung, how can it be so accurate, not to cut off the scalp, but to cut the neck?"

For this reason, if the wire is stationary and the actor's height keeps rising, it is basically difficult to guarantee that the wire will not cut elsewhere.

Bao Laohei was not convinced: "As long as we make accurate calculations, this kind of thing can still be calculated."

"How highly educated do you think these acrobats are? They basically can't even write their own names. You ask them to calculate? What to calculate? Centrifugal force, centripetal force or something else?"

Lu Bufan stunned Bao Laohei until he was speechless, and Bao Laohei had no choice but to look at Xu Shan for help.

Xu Shan lowered his head to eat the noodles. The staple food he just ordered, the noodles were fragrant. This reminded Xu Shan of his experience in the school cafeteria. He suddenly became hungry again. He rolled up the noodles with chopsticks and rolled them into a ball. Then put it in your mouth.

This is because he is not good at chopsticks and is in a hurry to eat noodles, so he developed this habit.

One advantage of eating noodles like this is that you eat it quickly and won’t overturn it.

Bao Laohei felt very unhappy when he saw that Xu Shan kept eating noodles and ignored him. He gestured to Su Jing with his eyes, asking her to say something to help him out. However, Su Jing was staring at Xu Shan eating noodles, and suddenly her face changed. He showed an expression of realization and said: "I understand. I understand how that actor lost his head."

One sentence is like throwing a pebble into the calm lake.

Suddenly everyone looked up at her.

Su Jing subconsciously puffed up her chest: "Actually, we were wrong. We always thought that the actor was killed by himself. He hit some mechanism and lost his head. But what if the actor committed suicide?"

"What does this have to do with suicide or homicide?"

"It does matter. If it is a homicide, it is extremely difficult to separate the body and head in the air. But if it is a suicide, it is very easy. Just tie a thin wire around his neck, fix the other end to the rack, and then rotate the rack at high speed. The wire will become tighter and tighter, and eventually the entire head will be severed, and the person's body and head will be separated. This kind of behavior should be possible as long as there is a high initial velocity. Yes. Isn’t that the case, Master Xu?”

Only then did Xu Shan raise his head. He had just been concentrating on eating noodles. While eating noodles, he was thinking about what kind of method could separate the actor's body and head. Unexpectedly, Su Jing broke the trap.

And she finally asked herself, did she think...

Xu Shan was truly a master. He immediately understood that Su Jing was inspired by her own noodle-eating movements.

He raised his thumb and said, "As expected of you, you are one of the members of Shinpachi. Your analytical skills have made great progress. I am very pleased."

Everyone else looked stunned.

Bao Laohei asked Su Jing: "Is this what Master Xu told you?"

Su Jing said proudly: "Do you still need to tell me? Master Xu has made it so obvious, but you still have to guess by yourself?"

Bao Laohei: "..."

Niu Yonggui and the three others were also infected by Su Jing, and each of them looked at Xu Shan with eyes filled with admiration.

Especially that Lu Bufan.

He was very unconvinced before, but after Su Jing finished talking about the design of the mechanism for the trapeze artist to cut his own neck, he was immediately convinced. And when he heard Su Jing say that she had thought of it after being prompted by Xu Shan, he was immediately convinced. I was extremely convinced of Xu Shan and almost fell to the ground.

Xu Shan laughed: "Actually, it doesn't matter. Everything comes from life. After eliminating all impossible options, the remaining option, no matter how bizarre it is, can only be the only correct option."

His eloquent speech made several other people want to write it down in their notebooks. They all sighed in their hearts: "You are indeed a brilliant detective. He casually solved the mystery that no one has solved for a year."

The happiest person is Niu Yonggui. He now firmly believes that this circus case will most likely be solved in the near future because of the detective Xu Shan.
