The tractor drove to the highest mountain in the vicinity, and Lin Xuexi's hanging heart finally let go, if Lifus really wanted to pull her to the barren mountains and mountains to join her, he would not choose such a bare mountain bag, and there was a lot of wind.

Lin Xuexi felt hot on her face at this time, she was ashamed of her dirty thoughts just now, why didn't she believe him? He has always been a courteous and humble gentleman! He's the man I Lin Xuexi fancies!

Lifus pulled down the handbrake, then took out a screwdriver from the toolbox, removed the horn in front of the car, disassembled the horn, and took out a doughnut-shaped magnet inside, he sucked the magnet to the iron sheet above the cab, and then took off the monkey watch and sucked it on top of the magnet.

"Borrow your knife and use it." Lifus stretched out his hand to Lin Xuexi.

Lin Xuexi took out the folding dagger from his pocket and handed it to Li Fus, feeling very uncomfortable.

"This knife was just given to me by him, but now he uses the word 'borrow', is he trying to draw a line with me?" Lin Xuexi began to think wildly, she kept looking at Li Fusi quietly, she didn't know what he was going to do, she couldn't understand or guess, but she knew that Li Fusi must have a reason for doing this, and she didn't say anything to ask.

Lifus stood on the footrest of the cab, one hand pressed on the open door, and the other hand began to adjust the angle of the monkey watch, the dagger was opened and stuffed between the monkey watch and the magnet, the blade from thin to thick allowed him to adjust the side gap between the monkey watch and the magnet, Lifus's expression was extremely focused, as if a master sculptor was completing his peerless masterpiece, every movement was slightly meticulous to the top.

Finally, as if he had finally finished, he carefully got out of the car, wiped the sweat from his forehead, and began the countdown in his mouth: "20, 19, 18, 17......"

Lin Xuexi didn't know what he was doing, but when his countdown finally reached zero, he seemed to be relieved for him. She had expected something earth-shattering to happen at the end of the countdown, but everything was quiet, as if nothing had happened at all. But from what she knew about Lifus, Lifus was definitely not a trickster, so something must have happened.

"Alright, the target is determined to be destroyed, let's go home."

Lifus picked up the monkey watch, put it back on his wrist, returned the folding dagger to Lin Xuexi, and threw the magnet and the parts on the horn into the toolbox, the vehicles of this world no longer need the function of the horn.

"Wait a minute, aren't you really going to explain what just happened?" On the way home of the tractor, Lin Xuexi finally couldn't help but ask, she thought that Li Fusi would take the initiative to explain, who knew that this guy would act as if nothing had happened, and she was so angry.

"Haha, I thought you didn't care." Lifus smiled treacherously, looking like he was underwhelmed.

"Cut, just forget it." Lin Xuexi pursed her lips and turned her face to the side.

"Wow! You look so cute when you're angry! Looks like you're going to be angrier in the future. ”

If it was Li Xinran sitting in the passenger seat at this time, she might have pounced directly and pinched Lifus's neck and bit Lifus's arm, shouting Lifus, you bastard or Lifus, do you have humanity or anything like that, but Lin Xuexi sat there and didn't move, she didn't speak, she just kept a pretty face as cold as ice, and silently pursed her mouth a little longer.

Li Fusi was quickly defeated, even if he knew that Lin Xuexi's anger was fake, he couldn't stand it.

"Okay, okay, Miss, don't be angry, can't I do it all?" Lifus begged for mercy again and again.

"Phew, who doesn't hear it?" The corners of Lin Xuexi's mouth showed a victor's smile.

"Don't listen, I just finished the task, and I haven't asked you for any payment yet." Lifus always likes to use obscure expressions to grasp the initiative of the conversation step by step, use some psychological skills, and then slowly get better.

"Huh? You mean...... Have you completed your mission? ”

"Hmm." Lifus knew it was not appropriate to express it too much at this point.

"You mean...... You killed Ben Ryan? ”

"Hmm."

"Just now?"

"Hmm."

"Are you going to know nothing more than um?" Lin Xuexi was really angry, knowing that he had a lot of questions to ask now, but this guy seemed to suddenly lose his words.

"Hmm."

What to do? I really want to hit him, this guy who people love and hate!

Lin Xuexi slowly breathed a sigh of relief and told herself to calm down, my sister is a lady!

"So, what did you use to kill Ben Ryan? Could it be the watch? "Lifus used three things from beginning to end, the magnet, the dagger, and the watch, and the magnet and the dagger certainly couldn't kill people from a distance, so it was clear that the key was on that watch.

"Hmm."

Lin Xuexi felt that she was about to go berserk, she glared at Lifus with a vicious gaze, and stopped asking questions.

Li Fusi was stared at by her uncomfortable, there was a creepy feeling, which made him sincerely panic and fidget, he peeked at Lin Xuexi from time to time, and found that she was still staring at him intently, so he quickly withdrew his gaze, as if he was a thief.

"Well, I'm scared of you." Lifus finally collapsed under the tremendous pressure of Lin Xuexi's gaze, "It's actually a gamma-ray burst. ”

"Gamma-ray bursts?" Lin Xuexi almost instantly forgot the anger just now.

"Yes, gamma-ray bursts. Strictly speaking, it is a miniature high-energy gamma-ray free laser emitter, based on particle reactions, which instantly produces a large number of co-directional parallel gamma rays with extremely high energy density, just like a miniature gamma-ray burst. Lifus began to explain patiently.

"Oh my God! Is the earth technology so advanced now? Wouldn't we be able to destroy a planet so easily? Lin Xuexi said excitedly.

"Not really." Lifus had to pour a basin of cold water, "The artificial gamma-ray bursts we can create now are not comparable to the gamma-ray bursts produced by the collapse and destruction of giant stars in the universe, or they are not a kind of energy at all, and the difference in power is more than a trillion times." ”

"Oh, okay." Lin Xuexi was a little disappointed, "Then what is the maximum power emitted by this watch of yours?" You don't have to tell me the exact number, I don't have an idea, you just tell me how destructive it can be. ”

"Hmm...... This is difficult to determine, the gamma-ray burst emitted by the monkey watch can only cause damage to organic lifeforms, unlike nuclear bombs, particle bombs, etc., which can have shock waves and light radiation, and the killing range and power are very intuitive. If you have to make a comparison, it can kill an immigrant on Europa hundreds of millions of kilometers away with a single blow when it first leaves the factory, but it must be guaranteed that the immigrant will not move for at least forty minutes, because assuming Europa is 750 million kilometers away from Earth at this time, it will take 40 minutes for a gamma-ray burst to reach Europa. ”

"Artificial gamma-ray bursts are extremely powerful weapons, they can penetrate almost any matter and are not reflected, and because they are the speed of light, they cannot be prevented, and if the power is infinite, it can theoretically attack infinite distances without taking into account the frequency reduction caused by redshifts. But the gamma-ray bursts we can produce are still in their infancy. ”

"Gamma-ray bursts are the most energy-compressed radiation source in the universe known, and if you want to kill a person, even if he hides deep underground, it won't help."

"However, the gamma-ray burst power emitted by the monkey watch is very small, and the obstacles must be reduced as much as possible to ensure that the power is not too much attenuation on the way, so I drove the car to the top of the mountain, where there is no mountain block, it happened that Ben Ryan seemed to be taking a nap, and the barrier between him and my monkey watch was only a wall of tens of centimeters, so the gamma-ray burst easily passed through the wall and silently performed a long-distance brain operation on him, and the cause of death was basically not found."

"But how did you locate Ben Ryan? Even if the altitude is high, there is a lot of dust in the air, and the resolution of the images sent back by satellites is not enough, so it is impossible to track them, right? As a tech fan, Lin always knows what questions to ask and when.

"You remember when I left a nanobot on Ben Ryan, right? In fact, I have two nanobots on my body, each of which carries a particle that has been quantum-entangled at the same time, so that as long as I always have a nanobot on my body, I can know the location of the other two nanobots by using the ultra-distant effect of quantum entanglement, even if they run out of the galaxy. ”

"All I need to do is get the nanobots to run into the nerve center of Ben Ryan's brain and release the rays there."

"And how did you adjust the launch angle of the monkey watch? Even if you knew where Ben Ryan's head was, it would be hard to hit, right? That's more than 100 kilometers! ”

Lin Xuexi became Zou Dufeng's student because of Fermi, although she had little opportunity to contact advanced technology, but Zou Dufeng's attitude towards the root of science was inherited by Lin Xuexi.

"That's because my retina is transplanted with an advanced photon localization scanning template, and if I want, I can cut the image I see in front of me into countless small equilateral squares, no more than a micron diagonal, and even accurately locate an area of one square decimeter on the moon, of course, without nanobot-assisted positioning, I can only lock on to objects within my sight."

"Well, I do believe my eyes can be cured now." Lin Xuexi used to be dissatisfied and scoffed at the development of science and technology more than 500 years later, but now she is beginning to admire it again, but in fact, she herself has lowered the standard.

"I'm sorry, Xiaoxi, you should know that the cloning technology is all in the hands of the Alliance, and your eyes may not be treated in a short time." Li Fusi said a little sadly, if possible, he really wanted to bear this pain instead of Lin Xuexi.

"It's okay, I'm starting to get used to it, my life is all picked up by you, no matter how you live, it's all earned, the only regret is that Ben Ryan died too easily, and he should be allowed to die in pain."

The injuries on Lin Xuexi's face and body have healed, which she scratched with her own fingernails, all of them are very shallow, and there is no scar left after healing, and the scratches on her legs have already scabbed, it is estimated that it will heal in another week, and now only the injury on her right eye is a problem.

"I know that you want to kill Ben Ryan at all costs to avenge your good friend, you told your story, you feel indebted to them, but in fact, you don't need to blame their death on yourself, you just made a suggestion, they are all adults with independent consciousness and ability to act, since they chose to go with you, it is equivalent to acquiescing to your suggestion, then of course it is your own destiny, didn't you yourself almost die?" Li Fusi felt that he had to help Lin Xuexi untie this knot.

"But I still can't forgive myself, Horod once raised objections, I ignored them, I was too self-righteous, too self-serving, I was a bad spirit."

Lin Xuexi said and spoke, tears flowed, she was too easily swayed by emotions.

Li Fusi really couldn't do anything about her, he stopped the car, hugged Lin Xuexi over, and then kissed her cheek.

"Don't think that pretending to cry can play tricks, what about my reward?"

Lin Xuexi was in no mood to cry all of a sudden, she hugged her chest with both hands, looked at Li Fusi in horror, and thought to herself that Li Fusi wouldn't really treat her in the car, right?
