Ye Fei understood the intention of arranging him to be the captain of the Aquila, and he only knew a little about the Aquila itself, but as the captain of a ship, he must know the battleship well, so this understanding is naturally far from enough.

"Captain Ye, I still have something to do, let's go first." After explaining the above instructions, Secretary Xie completed his work, said goodbye to Ye Fei politely, and said hello to Liu Gong, Shi Shiran left the assembly workshop.

Liu Gong was obviously very familiar with Secretary Xie, and even if he had said hello with a wave of his hand, he asked expectantly, "Captain Ye......"

"Liu Gong, you just keep calling me Xiao Ye." Ye Fei said.

"Okay, then I'm not polite to you, where are we going?" Liu Gong turned to the side of the control room with Ye Fei in tow, sat on a half-meter-high box, and motioned for Ye Fei to sit down as well.

Ye Feixin said, I don't know where you said? But he couldn't say this directly, he simply talked about it left and right, and directly changed the topic: "Liu Gong, I heard you introduce a lot of weapons just now, but why are they still those things?" The Americans' warships are all using neutron cannons, maybe there are some proton cannons, plasma cannons and the like, so we don't have any new weapons? ”

The second expeditionary fleet of the United States and Russia has just been established, perhaps because the Chinese expeditionary force has put too much pressure on the American and Russian militaries, and the two countries have coincidentally vigorously promoted the strength of the new fleet.

In the past few days since he returned to Earth, Ye Fei's ears were almost full.

"Neutron cannon?" Liu Gong showed a very playful expression, "Xiao Ye." Do you think the neutron cannon is powerful? ”

Ye Feixin said Of course it was powerful, otherwise how could the Americans put that kind of trick on the battleship, but looking at Liu Gong's expression, it seemed that he had dug a pit and waited for him to jump down, and when it came to his mouth, he became hesitant again: "That, it should be." ”

Liu Gong sighed in disappointment: "Xiao Ye, you are a soldier, and it is normal to not know the way." Let's put it this way, you know all about directed energy weapons, right? ”

"A little bit of understanding." Ye Fei was a little overwhelmed, and he didn't understand what he had done wrong.

"So what are the directed energy weapons you know?" Liu Gong is a senior professor who is good at following the path. He regarded Ye Fei as an ignorant student - the Aquila was his brainchild. The old engineer didn't want to see such an excellent battleship fall into the hands of a guy who didn't know how to learn, if he thought that Ye Fei was not suitable for commanding the Aquila, he would definitely make a suggestion to the top of the Heavenly Army to remove him through his own channels.

Ye Fei replied without thinking: "Laser cannon, microwave cannon, neutron cannon, proton cannon, ion cannon, and electronic cannon." I don't know if the antimatter cannon and the plasma cannon count. He didn't care if these weapons really existed, and told all the sci-fi weapons he had ever heard of.

Liu Gong was amused by Ye Fei's answer: "Xiao Ye." You let me tell me what you want to do. Two words: naïve! ”

Ye Fei also knew that his answer was not very reliable. After a burst of laughter, he argued: "At least the neutron cannon has been put into practical use, right?" ”

"Practicality?" Liu Gong shook his head for a while, "It's still far away." You're misleading the news. ”

"Huh?" Ye Fei really didn't expect this stubble, and hurriedly asked, "How do you say it?" ”

Liu Gong didn't answer and asked: "What do you think the neutron cannon is?" ”

This question really stopped Ye Fei, and he thought about it cautiously before answering: "It should be a weapon that launches a high-density beam of neutrons out of the arc through an accelerator." ”

"It's a good idea, but it can't be realized in reality." Liu Gong commented unceremoniously.

"For what?" Ye Fei hurriedly asked.

There are not many opportunities to meet a national-level expert like Liu Gong, the Americans have already used neutron cannons, and Ye Fei feels that he needs to learn more about the characteristics of this weapon.

The two sides have been fighting openly and secretly for hundreds of years, and if it were not for the appearance of the Outer Bone Man, it would have been impossible to become allies. Once the external threat disappears, a break between the two sides is a matter of time.

Liu Gong patted his forehead in embarrassment: "How can I tell you?" Neutrons are uncharged and are neutral particles, which are not constrained and affected by magnetic fields, while particle accelerators can only accelerate charged particles, so it is impossible for accelerators to emit neutrons directly, understand? ”

Ye Fei was stunned for a moment and nodded: "I understand, but the Americans' neutron cannon ......"

Liu Gongyi waved his hand: "I was about to say this, judging from my personal experience, the so-called neutron cannon in the United States cannot exist at all." First, a neutron alone is an unstable particle with an average lifetime of 14 minutes and 42 seconds decaying into a proton, emitting both an electron and an anti-electron neutrino. Therefore, neutrons can only be prepared temporarily, and it is impossible to prepare and store them in advance and release them during battle. ”

"Huh?" Ye Fei's eyes widened, "Can neutrons still decay?" ”

"It's terrible to be uneducated!" Liu Gong glared at Ye Fei with hatred, and continued, "I think there are two possibilities for the Americans' neutron cannons, one is that they use radioisotope neutron sources to get neutrons and directly bombard targets without acceleration. But the lethality of this is too small to have actual combat significance; Another possibility is to accelerate the protons with an accelerator, neutralizing the positive electricity of the protons at the muzzle...... No, the proton that gets the electron is a hydrogen atom, and it doesn't match the neutron at all...... Oh, by the way, there is also a possibility, that is, the Americans did not make any neutron cannons at all, and they simply put smoke bombs to mislead us! ”

Ye Fei's brain was confused, how could this be such a result?

"Don't believe me?" Liu Gong laughed sarcastically, "You soldiers, you only know how to fight, can't you learn some scientific knowledge?" If you look at it, you will know that there are few people in the Celestial Army who know how to do it, and maybe the Celestial Army Command has been working overtime and staying up late after hearing that the Americans have neutron cannons. ”

Ye Fei was pitifully speechless, feeling that he was an illiterate person who didn't understand anything in front of Liu Gong!

He hadn't felt this way in years since he left school.

"What about the proton cannon? It can always be accelerated, right? Ye Fei said without giving up.

Liu Gong sighed: "I'm a good person to do it to the end, the proton can indeed accelerate, but the proton cannon has no meaning at all." The protons emitted from the accelerator have a low density and no lethality, but what if the density is high? The positively charged protons themselves will repel each other, and it won't take long after flying away from the accelerator to scatter like the light of a flashlight, and the charged particles will be affected by the magnetic field. The old engineer couldn't help but burst into foul language.

He didn't target Ye Fei, but felt that all the officers of the Heavenly Army had the need to return to the furnace and recast.

Knowledge is the strength of the force, this sentence has been said for hundreds of years, why do people always ignore the importance of knowing the Tao?

"Doesn't that mean the electric cannon is also a joke?" No matter how stupid Ye Fei is, he also knows how to draw inferences from Lu Dao at this time.

Liu Gong shrugged. pursed his lips and gave Ye Fei a helpless expression.

Ye Fei felt like an idiot.

"And what kind of positive electron cannon. It's a joke. Liu Gong said in a downhole.

"What is a positive electron?" Ye Fei really hadn't heard of this kind of weapon.

"It's a positively charged electron, or an antimatter electron." Liu Gong said, "Positive electrons, or antimatter weapons, do have great power. However, when antimatter meets positive matter, both sides will annihilate each other and cancel each other out. There was an explosion and a huge amount of energy was generated. Therefore, antimatter can only be stored in a magnetic field. It can't come into contact with any positive matter, such a dangerous thing, as long as the storage device is slightly malfunctioning, it can directly blow up the battleship into cosmic dust. Do you dare to ask for one if I install one for you? ”

Ye Fei hurriedly waved his hand and thanked Bumin: "Forget it, isn't this a time bomb around you?" ”

Liu Gong handed him a teachable look: "So, so far, the only practical directed energy weapon is the laser cannon, and the microwave cannon is also a directed energy weapon, but the power range cannot be compared with the laser." ”

"What about the ion cannon? Isn't it the same as the proton cannon? Ye Fei asked humbly.

"I don't really have much research on the ion cannon, theoretically it should have some power if it fires heavy nuclear ions, but the launch cost is definitely not low, and it is flashy, far from being as cheap as a laser." Liu Gong said while thinking about it, he suddenly thought of something, stared at Ye Fei's eyes and asked, "What is the Heavy Nuclear Ion Dao?" ”

Ye Fei shook his head stiffly, almost wanting to find a crack in the ground to get into.

"It is the nucleus of an atom that has lost its electrons outside the nucleus, such as iron and copper. When a supernova explodes, it produces large numbers of heavy nuclear ions that travel across the universe at nearly the speed of light, shattering the helix of DNA as it penetrates the human body. If the protective layer of the spacecraft is not up to standard, the people in the spacecraft are in danger of being hit by heavy nuclear ions. Speaking of this, Liu Gong patted Ye Fei's shoulder seriously, "Xiao Ye, there is no end to learning, people have to live to learn all the time, and knowledge is not enough no matter when it comes." ”

"Yes, you're always right, if I had met you decades earlier, maybe I wouldn't have been in the army and would have been admitted to college directly." Ye Fei said flatteringly.

"You're a good kid, at least better than those stupid people who hold a shelf and don't listen to any opinions." Liu Gong rarely praised Ye Fei twice, and he didn't know if Lu Dao was sincere.

Ye Fei struck while the iron was hot: "Old Liu, you see that you have said so much, can you tell me more about that plasma cannon......

"This, plasma, also known as plasma, is a mass of matter produced by the ionization of atoms and atomic clusters after some electrons are deprived, which is mainly an ionized gaseous substance composed of positive and negative electrons, which is the fourth state in addition to solid, liquid and gaseous states......"

"Old Liu, just spare me, say something I can understand." Ye Fei interrupted Liu Gong's statement in disappointment.

Liu Gong was stunned for a moment, and scratched his head embarrassedly: "To put it simply, plasma is a mass of gas at high temperature and high pressure, think about it, what is the effect of such a mass of things from the muzzle?" ”

Ye Fei realized: "Water will quickly vaporize if thrown into a vacuum, and if the plasma is thrown out, it will definitely explode immediately." ”

"That's right, it's like setting off a big firework." Liu Gong said with satisfaction, "Xiao Ye, don't let science fiction mislead, not everything can be a weapon, and not anything that can be used as a weapon must be practical, I don't know how many seemingly powerful weapons in this world are just an illusory concept, and there is no possibility of success at all." Don't look at Uncle Sam's loud shouting, but whether it succeeds or not, you have to see it on the battlefield. Our weapons are indeed a bit conservative, but which ones have not been tested in actual combat? ”

"Old Liu, I'm too abrupt." Ye Fei humbly admitted his mistake. "Actually, I don't think the neutron cannon is so powerful, don't we have a neutron cannon and haven't hit the bullet? I just didn't want to. ”

"Unwilling to what?" Liu Gong asked curiously.

People like him who are engaged in scientific research are surprisingly curious.

Ye Fei sighed: "I am unwilling that they have new weapons......

"Ha Lu Ha ......" Liu Gong laughed heartily, "Who said we don't have new weapons?" Xiao Ye, how many tough battles our expeditionary force has fought, and how many exoskeletons have been killed, you know better than my old man, is it necessary for us to play that gimmick? Isn't it because the Americans and Russians are doing this because their fleets are not at a disadvantage? ”

Hearing this, Ye Fei smiled embarrassedly, but he quickly caught the loophole in Liu Gong's words: "Old Liu, the new weapon you said ......"

"If you don't ask, I'll have to talk to you." Liu Gong laughed again. "You soldiers are fighting the front lines. When we are engaged in scientific research, do we eat dry food? ”

"No, I didn't mean that. Isn't such a large warship the result of research? Ye Fei hurriedly denied it, on the one hand, he really couldn't afford to offend, and on the other hand, he respected this old expert from the bottom of his heart.

Liu Gong is a national treasure-level technical expert. It's not the ones who don't know what to say. The brick family who only knows how to sell fame and reputation is called a beast.

"You have a point." Liu Gong said.

"That new weapon......" Ye Fei quietly rubbed the sweat on his palm. The heart said how this old man was moody, it was really difficult to deal with.

"Oh, yes. New weapons. Liu Gong pointed to the Skyhawk, "Needless to say, the 50MM near-defense artillery system is two parallel six-barreled Gatling rapid-fire guns plus four short-range anti-aircraft missiles, which is not a new thing." Do you know about light-speed torpedoes? ”

Ye Fei nodded: "Very familiar, I am the captain of the assault ship." ”

"The new torpedo is reduced in size and power, which is a good thing, but unfortunately it is only small compared to the old model, in fact, it is still too large." Speaking of this, Liu Gong pointed to the belly of the Aquila, lowered his voice and said, "The secret weapon I am talking about is the large-caliber heavy cannon in the middle of the belly of the ship!" ”

"Huh? What kind of secret weapon is the reconnection gun? Ye Fei couldn't cry or laugh for a while, this old man wasn't playing with people, right?

Liu Gong glared at Ye Fei dissatisfiedly: "Don't you scold me in your heart?" It's true that the heavy cannon is not a secret weapon, the secret weapon is the shell of the heavy artillery! ”

"How?" Ye Fei suddenly became interested.

Liu Gong smiled proudly: "Not long ago, we successfully realized the miniaturization of artificial gravity devices. ”

"What do you mean?" Ye Fei was confused for a while, what does the miniaturization of artificial gravity equipment have to do with secret weapons? This answer is simply that the donkey's lips are not the horse's mouth.

"You're stupid!" Liu Gong glared angrily, "We have created a small gravity cannonball, and use the heavy cannon to launch it, and the charging structure in the cannonball can use the energy of high-speed flight to charge the gravity device in the cannonball, and according to the difference in flight distance, it can produce a gravitational force of up to about sixty times the standard gravity after hitting the target, and the gravity can last for about five to seven seconds......

Ye Fei's buttocks slid underneath, and his eyes slammed into the ground: "Heavy, gravity cannonballs?" ”

"Shhhhh Liu Gong hurriedly pulled Ye Fei and looked at the other people's positions with a thief's head, "If you weren't the captain of the Aquila, I wouldn't tell you." ”

Ye Fei immediately lowered his voice like the thief who stole the wallet: "How many cannonballs?" ”

"The shell bay can hold a hundred, but this thing is a new thing, and mass production has not yet begun, and now there are only sixty or seventy on the ship." Liu Gong bit Ye Fei's ear and said.

Ye Fei's eyes lit up, and he couldn't wait to get on the ship now to see what the gravity shell looked like.

"Xiaoye, Xiaoye!" Liu Gonglian shouted a few times before calling back Ye Fei's soul, "Hear clearly, the farther the distance, the more fully charged the cannonball, and the higher the gravity generated, the lowest can only produce more than ten times the gravity, and the gravitational radius is about fifty to seventy kilometers, don't be too close to the target when launching." ”

Ye Fei grabbed Liu Gong's dry hand and shook it vigorously, "Old Liu, I don't know what to say, how did you come up with such a strong weapon?" ”

It's against the sky, it's definitely against the sky.

Imagine, if a person weighs 50 kilograms, once the gravity bomb explodes, it will instantly become three tons, and it will not be immediately pressed into a meatloaf?

Even if a bio-warship can resist a high level of gravity, it would be great if a gravity projectile was fired and then a normal cannonball was fired, and the strong gravity would definitely greatly enhance the power of the normal cannonball...... Ye Fei could no longer stop himself from dreaming of victory.

"And ......"

"And?" Ye Fei was taken aback, "What other weapons?" ”

"It's not a weapon, it's a power." Liu Gong said, "The fusion reactor on the Aquila has been miniaturized to a certain extent without affecting the power, and after the whole ship is docked, there are 248 reactors on all the warships, and the explosive high-speed flight in a short period of time can exceed the theoretical speed limit, but I can't say how fast it is." However, the faster-than-light engine has a limited endurance, and the overrun energy supply may damage the engine, so it is not recommended that you do this, and the flight speed of more than seventy times is enough. ”

"Then why don't you install more faster-than-light speed and increase the speed a little more?" Ye Fei asked puzzledly, "Seventy times the speed is fast enough, but it is still too slow for the expeditionary force." ”

"Don't you want to be with us? There is also a limit to the stacking of power of the faster-than-light engine, theoretically no more than a hundred times the speed of light, and in that case, there will be no room for anything else on the entire Aquila except for the faster-than-light engine and the reactor. ”

"I see." (To be continued......)

PS: Cough, the setting of gravity cannonballs should be reasonable, right? Reasonable right!
