"It's possible. But I'll go to the physics lab to do an experiment before confirming it," Long Xi said.

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

Mo Kun asked Longxi, "Xixi, do you want to invite Mr. Xu to see your experiment?"

"Right. Mo Kun, you're a real mind reader. You always know what's on my mind," Long Xi said in surprise.

"We can reach a perfect mutual understanding while others can't! It has nothing to do with how long you have been known." Mo Kun glanced Xiaolu significantly.

Xiaolu was speechless.

Indeed, Xiaolu would never guess Long Xi's thoughts. He also confused that why Mo Kun knew Long Xi quite better than him. They just knew each other for several days, but he was Long Xi's over-two-year deskmate. It's strange!

No, he wouldn't give up! Although he didn't know Long Xi well, he sincerely loved her! He believed that sooner or later, Long Xi would understand his heart!

Though Xiaolu's logical reasoning ability was weak, his intuition was very sensitive.

He thought Mo Kun was dangerous!

He felt that Mo Kun was pretty familiar with Long Xi while Long Xi knew nothing about Mo Kun's real thoughts. Besides, Long Xi seemed utterly unaware that she was close to a dangerous man.

No, in any case, even if he were too weak to fight against Mo Kun, he would try his best to protect Long Xi!

After reading Xiaolu's ideas, Mo Kun sneered in mind and thought: "Looks like if I don't teach him a lesson, he won't give up pursuing Long Xi. The earth person's feeling is really complicated! The people in the BT planet don't have such problems."

He had to admit that Xiaolu was rather clever. At least his accurate intuition was right—Mo Kun was a dangerous man.

However, unfortunately, BT planet was at least five hundred years ahead of the earth in science and technology. Xiaolu himself was not interested in science. Thus he could never imagine Lord Mo Kun's subsidiary chip was hidden in his, Yan w.a.n.gchuan's and Long Xi's brains.

The subsidiary chip was unseen, even the scan of most sophisticated medical apparatuses on earth couldn't detect it.

Suddenly an evil idea flashed in Mo Kun's brain: "Why not make Fan Xiaolu the third human trial in succession to Cheng Yilun and Jiang Ba? Why not see if I can manipulate Fan Xiaolu's will after providing him a seven-day hallucination in one day."

"Should I let Fan Xiaolu know what it's like being manipulated by me?"

Well, forget it, he couldn't do harm to Fan Xiaolu—such an innocent and optimistic boy.

Long Xi didn't know Lord Mo Kun had such a hard struggling. Xiaolu also didn't aware that he just escaped from suffering because of Lord Mo Kun's kindness.

Long Xi called to invite Mr. Xu to come and see her physics experiment. Mr. Xu readily agreed.

Half an hour later, Long Xi stood in front of the laboratory bench of the physics lab and started a physical experiment in front of Mr. Xu, Xiaolu, Mo Kun, and Fu Xinjie.

She lifted a gla.s.s tube and said, "You see, one side of the tube is closed, there's a piston switch near the other side's head."

She sealed the opening of the gla.s.s tube with a thick rubber grommet and then turned on the piston switch.

She pa.s.sed the gla.s.s tube to Fu Xinjie and said, "Madame Fu, try and see if you can separate the gla.s.s tube from the rubber grommet."

Fu Xinjie smiled and said, "So easy!"

She was confident of her own strength. But after yanking hard with both hands, even exerted all her power, she was still unable to pull the rubber.

She wiped the sweat on her head, looked at Long Xi, and asked, "Why? Why as if there is a force holding the rubber grommet?"

Long Xi replied nothing but looked at Mr. Xu.

Mr. Xu said, "Long Xi, you do well in physics! I'm proud to be your physics teacher. Fu Xinjie, do you learn physics from a PE teacher? How don't you know such simple physical principles?"

Fu Xinjie blushed for shame.

Mo Kun replied, "It's vacuum suction! The suction of the vacuum is powerful! Unless you break the rubber grommet, it's impossible to pull it off completely by yourself."

Long Xi said, "I'll let you see for yourselves."

She took a steel needle from her bag and stuck it through the rubber into the gla.s.s tube.

Then, she retracted the steel needle.

A sharp sound that spread from the gla.s.s tube, like a gas leak.

About one minute later, Long Xi pulled slightly, the rubber grommet covering the opening of the gla.s.s tube was dropped.

Xiaolu was astonished. If Yan w.a.n.gchuan were standing here, he must understand the reason. Unluckily, there stood Yan w.a.n.gchuan's body, and Xiaolu himself didn't have enough physics knowledge.

Fu Xinjie didn't understand that, either.

Mr. Xu explained, "p.r.i.c.k the rubber and then let the air re-enter the gla.s.s tube, then, the vacuum suction is removed."

Xiaolu asked, "What all this has to do with the case?"

Mo Kun responded, "Isn't it obvious? Suppose you put a similar gla.s.s tube over the victim's lips and turn on the piston switch. The victim is unable to speak and struggle. Then, he will be paralyzed. Finally, the air of his lungs will be sucked off."

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

Long Xi said, "Then, the murderer could use the steel needle to drill a hole in the victim's face. When the vacuum suction is removed, he can remove the gla.s.s tube."

Xiaolu also understood, saying, "I see! In other words, the murderer mustn't be someone like me who lacks physics knowledge."

He looked at Mr. Xu involuntarily.

Mr. Xu was shocked and annoyed to say, "Are you suspecting me? Tell you what! Even if I do kill him, I will never do it with my physics knowledge. Do you know how divine physics means to me? I will never desecrate it! That's very shameful!"

He pointed at Xiaolu and said, "Yan w.a.n.gchuan, you are the subject representative of Physics. Although you are only in a senior one, your physics knowledge is no less than the college students, why you just deliberately pretended to be a physics idiot just now? Are you the murderer?"

Xiaolu said, "It's not me!"

Long Xi said, "I think the murder not only has such kind of knowledge but also can use it flexibly. Even people who have done this kind of physics experiment don't necessarily think of killing people in this way."

Fu Xinjie said, "But for Mr. Xu, it is a little difficult to carry out such murder on a living man unless the victim is unconscious."
