"Than Liliang?" Lu Yan asked in disbelief, he suspected that he had misheard, Xu Te was a thin little old man, and the mastiff could knock Xu Te down with a little finger, what strength did the two of them compare.

Seeing that Lu Yan didn't believe it, the scientist smiled and pointed to a corner on the right.

Lu Yan looked in that direction, and sure enough, he saw a group of people around there, all of them were wearing white coats, obviously scientists here, and they seemed to be watching the excitement.

"These scientists, when have they been so idle?"

Lu Yan guessed puzzled, seeing that the scientists next to him were all smiling, Lu Yan estimated that Xu Te must be using some kind of ghost idea to embarrass the mastiff.

Lu Yan hurriedly walked over.

Before he could get to the place, Lu Yan heard Xu Te shouting loudly to the mastiff: "You said it, science is useless, if I defeat you with scientific methods, you will have to listen to me in the future, right?"

"Hmph, I'm so happy to scream with my strength, okay, I promise you, but if I defeat you, I'll play with whatever I want in this factory in the future, right?" The mastiff's thunderous voice was heard very clearly in the closed hall.

"As I said, this is a laboratory, not a factory!" Hütt shouted again.

"Okay, okay, whatever you say, this is it anyway!" the mastiff agreed impatiently.

"Humph!"

Xu Te snorted heavily before he began to get down to business again: "Haode, then we'll make a decision, now I'll talk about the rules of the competition, you pull this end of the rope, I pull the other end of the rope, which of the two of us pulls the other off the ground, whoever wins, do you hear clearly?"

“haode。 ”

After the mastiff agreed, he looked up at the thick rope above his head and the dozen large and small pulleys hanging overhead, and saw that the rope turned around those pulleys one after another, zuihou led to the other end of Xute, the mastiff was very strange, and said disdainfully: "Is this science, hum, isn't it just a rope, no matter how small the circle is, how many pulleys are passed, in the end it is not liliang, I can still pull you off the ground like a chicken." ”

As soon as the scientists around heard the mastiff agree, they let out a coaxing daxiao.

Liu Xing didn't go to school either, so he didn't know what the mystery was.

At this time, Lu Yan had already walked into the crowd, and immediately looked up at the pulley device on the head of the mastiff and Xu Te, and at this time he finally knew the reason why these scientists were laughing.

Because, this device is exactly what they just learned in high school, the problem of force transformation under levers, and this is the most typical case.

[A person, can you pull yourself off the ground?] Under normal circumstances, it is impossible, on the one hand, you don't have a fulcrum, and even if you have a fulcrum, very few people will have such a big liliang with one arm.

However, it is different after the continuous decomposition of the liliang by the pulley, after several times of the pulley's decomposition of human gravity, the pulley can turn the weight of your body into 1/8, 1/16, 1/32 or even 1/64, when your weight becomes only like a kitten's weight, you can of course easily pull yourself off the ground through the pulley.

However, I didn't expect Xu Te to use this device here.

Now, the end that Xu Te let the horse mastiff hold is the end of the decomposition force, and the end that Xu Te himself holds is the most trouble-free end, so the scientists below are laughing, this way of comparing liliang, the horse mastiff has no way to win.

"Here we go!"

Xu Tefeng said lightly and proudly.

"Okay, be careful that your bones don't fall apart!" the mastiff reminded Hut loudly, and then began to pull the rope with both hands that was enough for a man's wrist.

Xu Te disdained only to hold the rope with one hand, and beat the ground rhythmically with the toe of his right foot, looking like a villain.

"I'll pull!" the mastiff pulled hard, but after only a few pulls, he found that he could no longer pull the rope, because his liliang was broken down into 1/64, so he felt on Xut's side that the mastiff's liliang was like a kitten climbing on the rope.

However, the mastiff seemed to be pulling a mountain, his face turned red with the strength to feed, and he didn't see Xu Te move, on the contrary, Xu Te's leather shoes knocked on the ground more and more loudly.

"I don't believe it!"

The mastiff pulled the rope with both hands, and he completely hung his huge body, but he still saw that Xu Te did not move.

Depressed!

The mastiff yelled angrily: "It can't be that this rope is locked, how can I not pull it?"

"Hey, hey, hey"

Xu Te let out a shrill laugh, and then pretended to be as hideous as possible and yelled at the horse mastiff: "Let you see the liliang of science." ”

After saying that, Xu Te had already begun to pull up the rope quickly, and his end of the rope was quickly pulled down, and the whole rope also moved.

As soon as the mastiff saw that the whole rope was moving, the rope was naturally not locked, and he was busy pulling it hard.

But soon, a scene that shocked Ma Mastiff and Liu Xing appeared, Ma Mastiff's body like a machine god of war actually slowly left the ground, and he was easily pulled into the sky by Xu Te.

Yes, for the mastiff's end, it is equivalent to Xu Te's liliang is 64 times larger, so - the victory is immediate!

The mastiff's muscular face was completely petrified at the moment, and he was stunned for a long time before jumping off the rope, and he couldn't see anything strange after looking at the rope for a long time.

"Throw in the towel or not?"

Xu Te, a little old man, has a very heavy sense of victory and defeat, and he also shows off his power in front of the mastiff like a child.

It's like a little rooster proudly showing off in front of a big stupid bear.

Ma Mastiff's embarrassed face didn't know what to do, in fact, in front of a person of the same age as his father, there was nothing to be ashamed of admitting defeat, he just didn't know what the mystery was, so he lost so embarrassed: "Dr. Xu, this, what's going on?"

"This is the principle of leverage, and this is the liliang of science. ”

When Hütt said this, he was obviously proud of his identity as a scientist, and after a moment of pride, he asked the mastiff, "What did you promise me just now?"

Ma Mastiff is a cheerful person, and at the same time, he, who has never gone to school, still has some reverence in his heart for these knowledgeable people, and he immediately smiled at Xu Te and said, "Uncle Xu, I will listen to you in the future." ”

Xu Te saw that the mastiff was a cheerful person, and he also put away his smug expression at this time, but he didn't forget to carry out popular science education: "You must know that you lost to science, not to me." ”

"Yes, yes," the mastiff nodded vigorously.

Seeing that their competition was over, Lu Yan hurriedly walked towards Xu Te and Ma Mastiff.

Seeing Lu Yan coming, the mastiff's face immediately turned embarrassed, and he turned around and left, obviously he felt too embarrassed just now, this scene made Lu Yan see that he really couldn't raise his head, so he simply avoided it.

Lu Yan saw the mastiff walking away with a red face, he just shook his head and smiled helplessly, he had an urgent matter to find Dr. Xu, and walked directly to Dr. Xu.

"Dr. Xu, I don't know when my knife will be made, I want to enter the forest again tonight. Lu Yan asked directly, he knew that Dr. Xu liked this, because it didn't take time.

"Oh, by the way, I was looking for you. I've already made your knife, take a look. After saying that, Xu Te pulled Lu Yan towards the noisiest place in this laboratory.

"So fast!" Lu Yan's mood immediately became excited, this doesn't mean that he has to have a weapon in his hand, and this is the first one on the earth. Elemental weapons, this represents the highest level of earth material science and technology now, that is, high technology, Lu Yan forced his throbbing chest to follow.

In one corner, there are many machine tools roaring.

"This is the experimental finished product manufacturing area. Xu Te introduced as he walked, as if he was afraid that Lu Yan would think that this place was the workshop of the factory.

"Our first '?' What about elemental samples?" asked Hütter, looking to the people behind a few machines.

"Oh, here. ”

Immediately, two slightly younger old scientists ran out, and when they arrived at a machine tool, they struggled to carry out a strange thing that resembled the color of a cement slab, and it looked a bit like something made by Neolithic primitive people.

"This, what is this?" Lu Yan's eyes widened, and his heart rose to his throat.

"Knives!" Xu Te replied indifferently.

Lu Yan looked at Xu Te in horror, and confirmed in disbelief: "This is the knife made for me?"

"Hmm. Hutter nodded again.

Lu Yan almost collapsed, and he was worried about this first one produced on the earth. All kinds of beautiful fantasies that elemental weapons have, in an instant, were shattered by the so-called knife in front of them.

The gray color of rat's skin is not in any way able to make people think that it is a high-tech product. The strange shape makes it difficult for people to associate this thing with a 'knife', and if it has to be said to be a knife, it can only be associated with a 'wood knife' at most.

Xu Te saw that Lu Yan was delayed in taking the knife, and he also guessed the reason, and he hurriedly explained to Lu Yan: "Because it is the first knife, we don't think too much about the appearance of the weapon, and besides, it takes a lot of time to make a new knife model, so we mainly consider the performance of this weapon." In terms of length, weight, and stiffness, it definitely meets your requirements. ”

Hearing Dr. Xu explain so much, Lu Yan was embarrassed not to take the knife, so he had to take the 'firewood knife'.

"It's okay, there's a blade. Lu Yan looked at this knife painfully, looking at this knife, which made Lu Yan think of aliens, he was wondering, whether high-tech must be associated with ugliness in order to be called real high-tech.

"President Lu, what are you holding in your hand?"

At this time, the mastiff suddenly walked over, with a smile on his face, and called President Lu, obviously coming to Lu Yan to 'pick up laughter' and find balance.

Ma Mastiff and Liu Xing saw Lu Yan coming, in fact, they had been observing what Lu Yan was going to do on the side, of course they also heard the conversation between Lu Yan and Xu Te, when they heard Xu Te say that it was a knife made for Lu Yan, Ma Mastiff saw the appearance of the knife, and laughed so much that his stomach hurt.

Lu Yan glanced at the mastiff, and then deliberately angry at the mastiff and said, "This is a high-tech weapon. ”

"Go, who are you fooling?" the mastiff finally laughed.

Liu Xing also pursed his lips and smiled.

However, a pair of eyes stared at the mastiff who was smiling unscrupulously, Xu Te rolled his eyes and looked at someone coldly, he was very dissatisfied with the horse mastiff's laughter, which was tantamount to satirizing Xu Te's work, he immediately turned to the horse mastiff and said:

"Don't you believe it? Then bring me your own weapon, and I'll show you how powerful it is. ”

Scratching his head, the mastiff thought about it in embarrassment, but when he looked at the 'thing' in Lu Yan's hand again, he showed disdain, the mastiff didn't want anyone to say a word 'high-tech' to scare himself, he said unconvinced: "Hmph! Take it, I really don't believe it." ”
