"It's possible. I'm going to go to the physics lab and do an experiment before I can be sure. Long Xi said.

Fan Xiaolu said, "I'll go with you." ”

Mo Kun asked, "Xixi, do you want to call Teacher Xu over and let him watch you do the experiment?"

"yes. Mokun, you are really a roundworm in my stomach, I think you know everything. Long Xi exclaimed.

"This is called having a clear mind, others can't do it, it has nothing to do with how long you've known each other. Mokun glanced at the fawn meaningfully.

The fawn was speechless.

Indeed, Xiaolu couldn't guess Long Xi's thoughts, and he didn't understand why Mo Kun and Long Xi had only known each other for a few days, and why did Mo Kun seem to know much more about Long Xi than he had been at the same table with Long Xi for more than two years?

No, he won't admit defeat! Although he doesn't know Long Xi well enough, he is sincere to Long Xi! He believes that Long Xi will understand his mind sooner or later!

Although Xiaolu's logical reasoning ability is relatively weak, his intuition is very sensitive.

He smelled danger in Mokun's body!

He could feel that Mokun knew Long Xi very well, but Long Xi didn't know anything about the real Mokun. Moreover, she seemed completely unaware that she was next to a dangerous person.

No, no matter what, even if it is an egg hitting a stone, he has to do his best to protect Long Xi!

Mo Kun, who obtained Xiaolu's idea, sneered in his heart: It seems that if Xiaolu doesn't suffer a little, he won't give up Longxi. The emotional world of the earthlings is really complicated! The people of BT don't have this kind of trouble!

He felt that Xiaolu was actually quite smart, at least his intuition was very accurate, and he could intuitively feel that he was a dangerous person.

But it's a pity that the technology of BT planet is at least five hundred years ahead of the earth's technology, and Xiaolu himself has no interest in science, he can't imagine that he and Yan Lichuan and Long Xi have the auxiliary chip of Lord Mokun in their heads.

The accessory chip is invisible, and even the most detailed brain scans of the brain with the most advanced medical equipment on Earth cannot detect it.

An evil thought suddenly flashed in Mo Kun's heart: Why don't you take this eye-catching Fan Xiaolu as the third human test subject after Cheng Yilun and Jiang Ba? Try to make him hallucinate seven days a day to see if you can manipulate his will?

Do you want Fan Xiaolu to try the taste of being manipulated by someone's will?

Alas, forget it, he still can't do such a poisonous hand to a kind and innocent sunny man like Fan Xiaolu.

Long Xi didn't know that Lord Mokun had such a tortuous mental journey, and Xiaolu didn't know that he had just escaped a catastrophe because of Lord Mokun's kindness.

Long Xi made a phone call to Mr. Xu and invited him to come and see him do physics experiments, and Mr. Xu readily agreed.

Half an hour later, Long Xi stood in front of the experimental workbench in the physics laboratory and began to do a physics experiment in front of Mr. Xu, Xiaolu, Mo Kun, and Fu Xinjie.

She held up a glass tube and said, "Look, this tube is closed at one end, and there's a piston switch at the other end near the opening. ”

She sealed the opening of the glass tube with a thick rubber sleeve and turned on the piston switch.

She handed the glass tube to Fu Xinjie and said, "Fu Jinghua, you can try it and see if you can separate the glass tube from the rubber case." ”

Fu Xinjie smiled and said, "It's not simple?"

She was so confident in her strength that she pulled hard with both hands, and even tried to feed, but she was never able to pull the rubber away.

She wiped the sweat from her head, looked at Long Xi in confusion, and asked, "Why is this? Why does there seem to be a force pulling the rubber case?"

Long Xi didn't answer, and looked at Teacher Xu.

Teacher Xu said: "Long Xi, it seems that your physics has not been studied in vain! As your physics teacher, I feel very gratified. Fu Xinjie, your physics teacher taught you, right? I don't know such a simple physics principle?"

Fu Xinjie was so ashamed that his face was red.

Mo Kun said: "It's vacuum suction! The suction power of the vacuum is very strong! Unless you break the rubber case, it is absolutely impossible to pull the rubber case completely by your own strength." ”

Long Xi said: "Let you see it with your own eyes!"

She took a steel needle out of her bag, pierced through the eraser, and stabbed it into the glass tube.

Then, she withdrew the steel needle.

There was a high-pitched, gas-leaking sound from inside the glass tube.

After about a minute, Long Xi pulled lightly and pulled the rubber sleeve covering the opening of the glass tube away.

The fawn was dumbfounded. If it was the real Yan Lichuan standing here at this time, he would definitely understand. It's a pity that standing here is only the shell of Yan Lichuan, and Xiaolu's own physical knowledge is not very rich.

Fu Xinjie didn't understand either.

Teacher Xu said: "Puncture the eraser and let the air re-enter the glass tube, and the vacuum suction will be eliminated." ”

The fawn asked, "Then what does this experiment have to do with the murder?"

"Isn't that obvious? Suppose you put a similar glass tube over the lips of the deceased and turn on the piston switch. Then, the deceased will be unable to speak, unable to struggle, paralyzed, and the air in the lungs will be sucked out by it. ”

Fu Xinjie suddenly realized and said, "In this way, the deceased will die within two minutes." ”

Long Xi said: "Then, the murderer used a steel needle to drill a hole in the deceased's face, and the vacuum suction was eliminated, and the glass tube could be removed." ”

Xiaolu also understood, and said, "I see! In this case, the murderer must not be a person like me who is poor in physical knowledge." ”

He couldn't help but look at Teacher Xu.

Teacher Xu was stunned for a moment, and then said angrily: "Are you suspicious of me? I tell you, even if I really killed him, I would never use physical methods to kill him." Do you know how sacred the temple of physics is to me? I will never desecrate it! That is a very shameful act!"

He pointed to Xiaolu again and said: "Yan Lichuan, you are the representative of the physics class, although you are only a freshman in high school, but your physics level is not inferior to that of a physics college student, why did you deliberately pretend to be a physics idiot just now?

The fawn said, "I was wronged!"

Long Xi said: "I think the murderer not only has this knowledge, but also can learn and apply this knowledge. Even people who have done this kind of physical experiment will not necessarily think of killing people in this way. ”

Fu Xinjie said: "With Teacher Xu's physique, unless the other party is in an unconscious state, it is still a little difficult to carry out this level of murder on that living man. ”
