"Okay, just kill him!"

Xiao Ruan said, and the two of them made the next plan.

Back in the room, sure enough, two people I didn't know were already there.

After seeing Lu Yu come back, he immediately rushed up and said, "Oh, my lord, you are back, where have you been for so long?"

Lu Yu blinked, and then said, "I didn't go anywhere, I just walked around here and walked around." ”

"Huh?" the two muttered, "That's not right, we've checked all the places with surveillance, but we haven't found them...... It's weird. ”

Lu Yu squinted his eyes and said, "That'...... What do you think I'm going to do, or do I have to report back to you if I'm going to do something?"

"No, no, of course you don't have to, that ...... Actually, there is nothing too big for us to come, it's just ...... I hope you can go to the front research room and help us solve some problems according to your ability......"

"Oh, yes. ”

"Young Master, you should take a break. ”

Lu Yu waved his hand and said, "It's okay, just take a walk, it doesn't matter." ”

With that, he followed the two men all the way to a large room, where there was something like a cannon, and about a hundred people gathered around it, discussing something.

Lu Yu blinked, looked the behemoth up and down, and then smiled: "Well, you finally have to work weapons? ”

As soon as the voice came out, everyone immediately turned their heads.

When everyone saw Lu Yu, although they didn't know him, they knew him.

Hurriedly turned his head and smiled, "My lord, are you here?"

Lu Yu nodded, feeling ...... Very comfortable.

You don't have to seize power or anything, everyone will respect you, and that's the difference between politicians and high technology.

Lu Yu is strong, even if he may not have any active ability, but it is too big to be able to resist his knowledge, that kind of high-level spaceships in other worlds have seen it, I am afraid that one or two points of guidance will be of great benefit to the people here.

So respect comes from the heart.

Lu Yu walked directly to the front, observed this thing that looked like a cannon up close, and then touched his chin and pointed a little above and said, "This...... When I first arrived, I shouldn't have been pointing fingers at your work, but ...... Will you allow me to say something?"

Everyone immediately said, "Of course, of course, of course! Is there something wrong with this part you are referring to?"

Lu Yu said: "Here, it looks like a cannon barrel, that is, no matter what is going to be launched here, it will rush out from here, right?"

"Yes, that's right. ”

"Hmm...... You've strengthened the barrel and added some formations to it, eh...... It seems that the material is also good. ”

"Yes, this is a cannon modified from an energy excitation device, and it is also the main gun of the ship, which must be much stronger than the light type that used to be, but this is only an idea, it has not been built yet, and an experiment has not been carried out. But...... I've already spent a lot of money, so I want to make it as perfect as possible, and then experiment or something, so as to save costs. ”

Lu Yu nodded and said: "That's right, this concept is correct, only when all parts of the construction have reached the expectations in my heart, and I can't change a little bit, I should carry out experiments, this is the best way." ”

"That's it, that's what we think. ”

Lu Yu said: "But...... Between the barrels, a material that you used before and after...... Seems a little inappropriate. ”

"This ...... We've hardened it several times...... Is it still a bit wrong? What is the reason for that?"

The person next to him hurriedly asked.

Lu Yu smiled, and then said, "If it's an energy ray, of course there won't be any problem with this design, but if you want to emit something else, especially ...... Probably...... Well, I just took a look, and I don't know your production philosophy yet, so ...... I'll speculate first, right or wrong, you can point it out. ”

"Okay, sir, please. ”

Lu Yu nodded, put his hands behind his back, circled around the huge machine, and then walked back, looking at those scientific researchers, his eyes were full of appreciation.

"Well, that's good, that's good, I didn't expect you to have already studied in this direction, it's really good! If I'm not mistaken, the means you want to use is a kind of microscopic matter excitation! In short, it is to use energy to stimulate the essence of something, which is not the energy of the atomic nucleus, but ...... The deeper energies, the deeper energies, although you may not know what these energies are, do not prevent them from discovering them, stimulating them, and using them...... Right?"

“......”

Everyone froze.

looked at Lu Yu like a monster, one by one in a daze, his mouth wide open and his eyes widened, full of incredulity.

The researcher next to him had been on the side for a while before he said, "Oh my God, we thought that you were only knowledgeable, and that you would only be able to get access to those cutting-edge things that we couldn't touch at all, but I really didn't expect that your Excellency would know so much about mechanical energy, and you could see the main concept and structure of this cannon just by looking at the surface of this cannon...... Oh my God, you've really opened our minds!"

Lu Yu waved his hand and said, "Don't say this kind of sycophancy, I don't like to hear it." ”

I don't like to listen to it, but Lu Yu's head is directly raised, and the corners of his eyes are constantly twitching, obviously happy.

The others immediately said: "My lord, this is not a sycophant, to be honest, your lord is really beyond our imagination, it is really amazing!"

Lu Yu snorted twice, and then said, "It is precisely because of such speculation that I said it...... There is a little problem with the manufacture of your cannon barrels. ”

"Oh, sir!"

Lu Yu nodded and said, "Just what you say, it doesn't seem to be very intuitive...... So be it. ”

As he spoke, Lu Yu stretched out his hand and shook it, and a pistol from his previous life appeared in his hand, and then he opened the safety and pulled the trigger, and with a bang, a bullet flew out directly.

Then he asked, "Have you ever seen this kind of firearm?"

Everyone looks at me, I look at you, but they all say that they have not seen it, and they don't even know anything about similar firearms, and they don't have them in books.

Everyone hurriedly shook their heads, and couldn't help but ask, "My lord...... Although this weapon doesn't feel powerful enough, it's powerful enough to have a special effect, right? Is it effective in inducing smoke? Hmm...... I'm afraid this is the weapon that the adults found from the spaceship of that high-level world, right?"

"Uh...... This ......"

The corners of Lu Yu's eyes twitched twice, in fact, he had already guessed that this world had never experienced the age of firearms.

To put it simply, this world is still a world of cultivation, and even if technology appears, it will come according to the energy of cultivation. Not only will there be less use of firearms, but there will also be no use of electricity.

In other words, this world has crossed the technological development route of Lu Yu's previous world.

Yes, there is such a convenient energy as cultivation energy, who the hell wants to study what black powder and what electricity?

All civilizations about 'fire' have been replaced by energy, so the steam engine, the internal combustion engine, these things that are pinned on flames, will not appear.

Coughing twice, Lu Yu said, "No, on the contrary, this thing...... It's a very low-level thing, low-level to ...... It's the kind of person who can't cultivate the entire planet, and he thinks of a way to survive in the natural world. ”

"Oh......" The crowd was stunned, and then a little disappointed.

Lu Yu said: "Take this thing and come out, just to give you an example...... Ahem, look at it. ”

As he spoke, Lu Yu fired a few more shots.

Yes, no one is afraid of this thing, in this room, even the weakest scientific researchers can easily block bullets with their own energy, and even the surrounding walls are full of ridicule for bullets, and the bullets with lead heads don't even have the ability to rebound, so they are directly smashed into flat ones one by one, and they fall to the ground helplessly.

The corners of Lu Yu's eyes twitched twice, then he turned his head and said to one of them, "Come, touch the barrel of this gun." ”

The other party walked over cautiously, not knowing what Lu Yu was going to do, but he still put his finger on the barrel of the pistol.

"Is it hot?"

"It's not hot. ”

"Hmm...... Then you touch the front. ”

The other party does so, and then ...... Ah screamed out, and hurriedly took his hand back.

Lu Yu asked again, "Is it hot?"

"Hot ......" The researcher was stunned for a moment, and then asked, "Why is this?!"

Lu Yu said: "The specific reason is very complicated, caused by many aspects, one is the flame of the explosion, the high temperature formed, only close to the muzzle part, there will be oxygen to make it burn, although the time is very short, but it will still produce a very strong high temperature." On the one hand, the barrel is not so straight, on the other hand, it is caused by gravity, or because of the convection of air formed by the combustion of the outside world, anyway, at the moment when the bullet is sprayed, it will produce the most serious friction, and the temperature produced is also the highest. ”

"Oh! I see. ”

Everyone suddenly realized, but at the same time, they still didn't know why Lu Yu wanted to do such an experiment.

Lu Yu smiled, and then said: " In addition to the previous kind of energy light, so something like this cannon, at the moment of shooting, the position of the front tip is always in the most vulnerable state, so the entire barrel is the same material, the same technology, or the part of the other barrel, does not play a good resonant acceleration function, there is a redundancy of resistance to loss, or the tip part of the barrel is unreliable, and it will be damaged soon, and even as long as it is a shot, it will be exploded directly. ”

"Huh?!"

When everyone heard this, they came to their senses at the same time, looked at the cannon blankly, and said with a wry smile for a while: "The previous technology is the foundation for us, and it is an existence that is enough to learn from and improve, but it is also an existence that restricts our progress......"
