There are two ways to defeat your opponent. First, make yourself stronger than your opponent. Second, make your opponent weaker than yourself.
Even if the deep space civilization has declined to the extreme at this moment, who can guarantee that there is no scientific and technological data from the past heyday left in their database? And relying on those scientific and technological data, as long as a powerful weapon that surpasses the times can be created, human civilization may never have any chance again.
They must, must, no matter what the cost, must be eliminated at this stage. If they cannot be eliminated, then weaken them and slow them down!
But before the meeting ended, the reminder from Xiao Xi was once again delivered to the Human Government Conference Room No. 1.
"Captain, I received another signal from the direction of Cygnus. This time the signal has a clear direction and is very clear, and it comes with a 'documentation' about this message. I have completed deciphering it."
The so-called "description document" is actually an information statement similar to a sample, or it can be called a "dictionary". The purpose is to provide enough samples for the recipient to decipher the language system.
People looked at each other and saw a hint of surprise.
A line of text was projected in front of people.
"Dear unknown civilization, hello. We are the 'deep space civilization' from the 'Seltoya' galaxy."
"Note: 'Seltoya' in their writing system probably means 'warm, comfortable, great' or something like that. At the same time, because we have named it 'Deep Space Civilization' Because of this, when translating the names of their civilizations, I did not use transliteration or literal translation, but directly replaced them with 'deep space civilization'."
"Based on the consistent rules of cosmic civilization, peace can only exist between civilizations of equal strength. Therefore, in order to prove your strength, we have made a small test. I hope you don't mind.
Now, you have proven your strength.
For the common interests of you and us, I propose on behalf of our civilization that we can abandon disputes, cooperate with each other, and establish good diplomatic relations. If you agree, please reply to us and attach your 'language dictionary' in accordance with the rules of universe civilization to facilitate further communication between us. "
One committee member slammed the table angrily.
"Despicable, shameless! They almost wiped us out, but now they are only pushing it lightly above the so-called code of cosmic civilization! If they are really sincere, why don't they compensate us?"
"They can't be trusted!"
Zhao Changxing looked at this line of words thoughtfully.
This information seems to contain some descriptions of the way of survival in this universe that Zhao Changxing has never come across before.
Although people have made many speculations about the existence of extraterrestrial civilizations as early as the earth's era, and believe that there is a high probability of intelligent life different from humans in the universe, but the speculations are only speculations and have never been actually found.
If there are many civilizations in the depths of the universe, then humans are completely confused as to how different civilizations can coexist.
Frankly speaking, Zhao Changxing believes that there is a certain rationality to the principle that "peace can only exist between civilizations of equal strength." Judging from this, it is not without the possibility of sincerity that the Deep Space Civilization proposed an agreement for peaceful coexistence after the exploratory attack failed.
Zhao Changxing smiled faintly and shook his head gently.
"Xiao Xi, reply to them, we are very happy to coexist peacefully with them. If possible, we hope that both parties can cooperate in technology, resources, industry, etc. It is mutually beneficial and win-win for everyone."
"Okay Captain."
"Leader, you..."
One of the committee members looked at Zhao Changxing, his eyes full of disbelief.
"Okay. Let's continue to discuss how to retaliate."
"Well……"
People living in a relatively simple social environment may not be able to react to Zhao Changxing's rapid change between the two attitudes. But after a while, they became more enlightened.
In the following discussion, with the help of Xiao Xi, people listed all the weapons they already have at this stage, as well as the weapons that can be manufactured at the current stage but have not yet been manufactured, or the weapons that can be manufactured in the future. Listed out one by one.
Interstellar missiles that can be loaded with nuclear bombs and conventional high-explosive ammunition can be propelled by chemical fuel propulsion or fusion plus ion propulsion. There are many types of land-based or space-based electromagnetic guns, electromagnetic pulse bombs, laser weapons, etc.
It has to be said that in the early Earth Age, humans still developed many types of weapons.
But after investigating one by one, people found that this variety of weapons seemed a little weak when facing a target that was more than 60 million kilometers away, and this target was definitely equipped with a considerable level of planetary defense system.
Interstellar missile - no matter what kind of bomb is loaded and which propulsion method is used, there is a problem, that is, the delivery speed is too slow, the target is too large, and it is easy to be discovered and intercepted and destroyed. Just like before on Sedna, the final interception was completed with only some relatively rudimentary planetary defense systems.
The same goes for electromagnetic pulse bombs. Laser weapons are not practical because they are too far away.
The only ones that can complete the strike are unguided weapons that rely on small size, low quality, fast speed, and large quantity to complete the killing, such as electromagnetic guns.
Even if the planet's defense system were hundreds of times better, it would be impossible to intercept millions of electromagnetic gun projectiles with a mass of only 0.5 grams and traveling at speeds of several kilometers per second.
From this perspective, it is very suitable for launching this revenge. But there is a very serious problem with this attack method, that is, the planet is too far away, and the electromagnetic guns that humans can make at the moment simply do not have this accuracy, and cannot be aimed accurately at all.
Even if the accuracy is sufficient and the target is accurately aimed, once the electromagnetic gun projectile leaves the barrel and enters the complex cosmic environment, its trajectory will be affected by many factors, such as planetary gravity, interstellar dust, cosmic radiation, etc. And its trajectory is uncontrolled. This means that even if you aim, you may not be able to hit the target.
At the end of the day, even if it hits its target, who knows, will it hit an open field or a man-made structure?
Want a full coverage strike, covering the entire planet's surface? Let's first increase the number of existing electromagnetic guns by ten thousand times and increase their performance by ten thousand times.
To sum up, electromagnetic gun weapons will not work either.
And... what about front-end and middle-stage guidance, such as using a rocket to transport an electromagnetic gun to a place not far from the deep space star, where it can launch an attack?
This still doesn't work. The target is too large and easily destroyed.
Or... blooming bombs? The missile warhead is loaded with 100,000 projectiles or more, and it is actively detonated before entering the opponent's planetary defense system, and the projectiles are dispersed to attack the opponent?
Nope either. One is that the offensive efficiency is too low, and the other is still the same problem, how do people control whether it hits open space or man-made buildings?
What Zhao Changxing hopes to achieve is to directly destroy the enemy once and for all. At worst, it will slow down the opponent's development progress, regardless of the gains and losses of one city or one place. Calculated this way, unless the electromagnetic gun can achieve the effect of cleaning the ground, the electromagnetic gun can only be eliminated.
Taken together, the only weapon that can achieve the goal is the hydrogen bomb.
At this moment, human civilization has not actually created a hydrogen bomb. But there is complete data in Xiaoxi's database. Combined with the current industrial capabilities, although it is difficult to actually create a hydrogen bomb, it is not impossible.
The difficult thing is, how to break through the planet's defense system and deliver the hydrogen bomb there?
"The key point is speed. If the speed of the missile is fast enough, it can escape the detection of deep space radar. At the worst, it can greatly increase the error of deep space radar, causing interception failure."
Faced with this problem, military industry experts are speechless.
Just like the high-power ion thruster used by the Spark spacecraft, it is impossible for people to build it now. It's too technical. Low-power ion thrusters have too little thrust to be used on missiles.
The only thing that can be used is still chemical fuel propulsion. Such as methane and liquid oxygen.
However, although the thrust of chemical fuel is large, the efficiency is too low. An interstellar missile whose fuel accounts for up to 70% of its total mass may not even reach a speed of 20 kilometers per second, and even the planetary defense system of Sedna cannot break through.
The combination of all kinds of contradictions makes the revenge operation face the danger of dystocia before it even begins.
"Or... at least use the electromagnetic gun and explosive shells to carry out a retaliatory action first to boost morale."
"No." Zhao Changxing refused directly: "This will completely fail to achieve the purpose of annihilating the opponent. It will also expose our war methods, which will easily cause Deep Sky Star to make targeted defense arrangements. It will be more difficult to attack next time."
Either don't do it, or do it to the extreme and get the maximum effect. Because there may only be one opportunity at this stage.
"At this stage, let's launch some spy satellites first, so that we can at least have a certain understanding of the enemy."
People looked at each other helplessly, and finally had no choice but to pass the resolution first.
At this moment, after experiencing this incident, all the loose atmosphere in the entire human society has disappeared. In major cities and bases, even the laughter and laughter are much less.
For the first time, people realized how precious the days of peace and carefree development are. For the first time, I felt the pressure that seemed to be everywhere.
Originally, Zhao Changxing thought that the social production order had been squeezed to the limit and that production efficiency was unlikely to be improved. But now, various statistics tell him that the overall production efficiency of society has increased by as much as 16.3%, which is an unexpected gain.
