"Are you serious? Someone is coming to attack Explorer Island?"

Li Huan, who was preparing to participate in the rocket launch ceremony, was full of incredulity after hearing the news. This can't be blamed on him, after all, this is the most brain-dead decision he has ever heard, there are people in this world who dare to sneak attack the explorer island? If the explorer island seems to have just arrived, and the construction has not been in contact with anyone, then Li Huan can completely understand that those bold outlaws can do anything for profit. But now it's different. The explorer island has long been famous, and has even attracted the attention of the territorial center, and now it is in conflict with the explorer island, is this brain-dead?

Especially now that the Multinational Force has arrived, the explorers on Explorer Island have just made plans, and it's time for the troops to be strong.

Doing things at this time, Li Huan wanted to know who they were.

"Is it someone from the territorial center?" Shangguan Qing is an old thinker after all, and likes to guess everything in a political way: "Is it that our actions have affected the territorial center, so they are sending people to spy on us, and our operation this time seems to be a bit big...... Is that a warning to us? If that's the case, then we need to send someone to talk to them. ”

"Do you need to ask? Surely, we're launching rockets here with a lot of fanfare, and although they don't know what this rocket is, they know we're ready to open up the world. Han Dong said with a grin: "At the beginning, they personally promised us to let us explore in this world, and don't the laws of this world also stipulate? Whoever opens up the dark world, the territory belongs to whom." If that's the case, then I think it's very necessary to give them a taste of the fruits of the third scientific and technological revolution. ”

The fruits of the third scientific and technological revolution have so far only been tried by Hiroshima and Nagasaki, and there is no doubt that this is what Han Dong is talking about.

Han Dong and Shangguan Qing guessed according to common sense, but they were very embarrassed, they guessed wrong this time.

"It's not a territorial hub, if it's a territorial hub, this matter is easy to handle. If the Territorial Center sends someone to ask for trouble, we just need to get Hannibal to submit a protest directly to the Territorial Center, so that we will be clear about a lot of trouble, but this time it is really not their trouble to find us. Li Huan rubbed his temples: "It's my enemy...... Well, I've always thought I'm pretty good at dealing with people, why am I suddenly full of enemies all over the world?"

"Enemy, Brother Huan, do you still have enemies here?" Han Dong's eyes lit up: "Tell me." ”

"There's nothing to say......" Li Huan sighed.

"There's nothing to say, don't interrupt my curiosity!" Han Dong's gossip heart burned.

"What's there to be curious about, isn't it some conflict that occurred when I came to this world, the information I just got was a sneak attack by a group of pirates, I have dealt with pirates only once, that is, I just now

When I came into this world. Li Huan pouted: "When I first came to this world, I met a group of pirates who were robbing and trafficking in human beings, so I stopped him and killed the pirate leader after taking it down." It's as simple as that, there's nothing else to say, I guess it's a friend or relative of the pirate who is coming to take revenge, right?"

"Pirates, don't all pirates should be caught and killed, this is a common convention in the world, I think it is like this in any world, that guy is not human. Han Dong nodded, and then became excited: "Alas, but both of you have encountered pirates. Brother Huan, don't talk about it, when Shangguan Qing was on a peacekeeping mission in the Gulf of Aden, he must have encountered a lot of pirates...... I've been watching Pirates of the Caribbean for so long, and I really haven't met a real pirate!

Li Huan and Shangguan Qing glanced at each other and shook their heads helplessly.

The two of them had not only seen pirates, but also said with their conscience that Li Huan was now the biggest pirate leader in the Gulf of Aden.

After Li Huan cleaned up several pirate organizations in the Gulf of Aden, especially because of the appearance of Xiao Maruko, now the pirates in the Gulf of Aden feel that Li Huan is the master of that ocean. So far, Li Huan's order not to harm Huaxia merchant ships is still carried out as a ban. Therefore, all Chinese ships in the Gulf of Aden can now pass unimpeded. Although the Gulf of Aden is still a very, very dangerous water area for other ships, and it will be abducted by pirates if you are not careful, but for the Chinese ships alone, with Li Huan, the biggest pirate leader, behind the scenes, all the Chinese ships can pass safely.

"Today we are preparing to launch rockets, and the security on the island is also the strictest, I really feel sorry for them, as a pirate, shouldn't you avoid a head-on conflict?" Han Dong sighed.

"That's not what you say...... Thanks to this intelligence warning, you don't know, when launching a rocket, we are actually like standing next to a nuclear bomb. Shangguan Qing frowned and thought for a while: "In this case, let's withdraw the fuel first after this launch, otherwise if there is really any trouble, it will be really a big trouble." Not to mention the rest, if this rocket fuel explodes, the entire Explorer Island will be destroyed in one fell swoop. ”

The fuels commonly used in rockets, metamethylhydrazine and nitrogen tetroxide, are highly toxic, volatile, soluble in water and can penetrate from the skin. Therefore, anyone who does not wear a chemical protective suit near the rocket wreckage can be poisoned.

The main components of rocket fuel are liquid hydrogen and liquid oxygen.

Hydrogen is the most reactive of all elements, and it is extremely difficult to control the combustion of liquid hydrogen. Therefore, liquid hydrogen is generally not used as fuel for the first and second stage rockets to avoid accidents that explode during low-altitude launches. It is mostly used as a propellant for high-energy last-stage rockets in high-altitude navigation. Once a high concentration of liquid oxygen and liquid hydrogen explodes, the power is not much less than that of explosives of the same weight.

The most important thing is that "hydrazine" is commonly used in rocket liquid inclamenants.

Hydrazine is a class of nitrogen-containing compounds that are toxic, corrosive, oily liquids. Most of the fuel used in the first and second stages of launch vehicles is used

"Binary propellant" of metadimethylhydrazine and nitrogen tetroxide. However, metamethylhydrazine is more toxic and damages the human liver. In particular, the combustion products of nitrous tetroxide or metamethylhydrazine are more damaging to the human body and seriously pollute the environment, which is very dangerous in perfusion operations. In addition, metamethylhydrazine is corrosive, and once the "meteorological time window" of the rocket launch is missed for a period of time, the rocket body must be replaced.

"That's not necessary. I don't think they can beat it, and it's good that they can rely on the outermost defense of the explorer island. Li Huan shook his head and said: "On Earth, if we miss the rocket launch time, then it's better to replace the rocket elevator again, but it's too troublesome here, so let's go out and intercept that guy." ”

"Then make sure it's safe. Shangguan Qing was still a little worried.

"Look at the defensive arrangement on our island, not to mention a few pirates using wooden sailboats, even if a modern warship breaks in, it must be a silent fate, there can be no accidents at all, Shangguan, you are too worried. Han Dong said with a grin: "Brother Huan doesn't need you, you two can watch the rocket launch here, I have never fought with pirates when those children came to me, this is still a very new experience." After defeating a bunch of pirates, I went back and had a lot to brag about. ”

"Are you really alone? Let me tell you, the pirates of this world are not like you think, they only use knives and guns, they can drive monsters. An careless word...... "Li Huan let Shangguan Qing say that he was also a little worried.

"So what? Our warships are all made. I know that the islands of this world can drive demon beasts, and those demon beasts are also a bit evil, but they can't pass through the blockade of warships. Han Dong said grinningly: "If anyone can pass through the blockade circle of the warship, then I will admit it, and I will not brag in the future." ”

"Do you think those pirates happen to have some information and know that we are going to launch rockets today, so they will rush towards the rocket launch position desperately......? Desperately rushing to the rocket to destroy it, then our island is really dangerous, after all, there is no big difference between us and a nuclear bomb in front of us. Shangguan Qing groaned.

"They know it's a rocket, I don't think they even know what it is, maybe when the rocket is launched, they will be curious to look under the vent......" Han Dong waved his hand: "You can sit here with peace of mind, just let me do these things." You always think things are complicated, but you don't need to think about things so complicated, just these two guys, you just invite him to the side of the rocket, and he doesn't know where to attack, is there still people in modern society who can serve as advisers to them? Even if there are modern people who cross over to them as advisers, then there are still a few defensive circles of warships!"

"Well, what you said makes sense, in short, just be careful of them, if you see anything unusual about their magical beasts, you must seal them outside the defensive circle, after all, once this explorer island explodes, then our hard work will be ruined. Li Huan said: "Then this task will be handed over to you." ”
