The last human in the universe

Chapter 56 Cover
At this stage, the deep space civilization must have suffered extremely heavy losses.This kind of loss is not only reflected in the economy, population, and various industrial facilities, but also in the planetary defense system.

Not to mention space-based electromagnetic guns, laser cannons, etc., at least, the various anti-aircraft weapons equipped on the surface are almost destroyed, right?This means that before the speed of 29 kilometers per second was required, the probability of breaking through the defense could be more than 30%, but now it may only need a speed of 19 kilometers per second to achieve the same probability.

How could Zhao Changxing miss this good opportunity?

Just a little awkward.

The hydrogen bomb was built too slowly.

There is no technical difficulty in making atomic bombs, hydrogen bombs, or chemically fueled interstellar missiles.The difficulty lies in the lack of raw materials.

Here on Star Sedna, there is really too little fissile material that can make atomic bombs.The atomic bomb is the only way to detonate the hydrogen bomb at this stage.

Strictly speaking, new high-explosives such as total nitrogen anion salts, which belong to the category of chemical explosives, can also achieve the effect of detonating a hydrogen bomb.But such an advanced energetic material, to be honest, has a higher technological content than the manufacture of atomic bombs, and human civilization cannot manufacture it at this stage.

The five missiles launched before have consumed all the fissile materials accumulated over the years.If you want to make another atomic bomb, you have to accumulate bit by bit and refine bit by bit.

This is also the reason why Zhao Changxing did not launch subsequent hydrogen bombs immediately after the five interstellar missiles with hydrogen bombs in their warheads.

"Leader of the report, we have been working overtime to purify fissile materials during this period. It is estimated that in another two months, enough fissile materials to make an atomic bomb will be ready."

"Okay, then, let's launch another hydrogen bomb over there!"

With a wave of Zhao Changxing's hand, the matter was finalized.

"By the way, don't dismantle the 'cables' connected to the No. [-] space elevator. Let's build it into a fixed launch pad."

"Yes."

Through the rotation of the Sedna star, the method of "throwing" the things that need to be launched seems to have an irreplaceable advantage now.This method must of course be preserved.It is nothing more than that the construction of the No. [-] space elevator was delayed for a period of time, and the current human civilization can afford to wait.

Zhao Changxing even planned to build a longer space elevator in the future.

If the length of the space elevator cable can reach 5.32 kilometers, then the linear velocity at the end of the space elevator will be as high as 10 kilometers per second, which is almost comparable to the launch speed of the electromagnetic gun projectile.If the length is 18.32 kilometers, it will be even more remarkable, and the linear speed will be as high as [-] kilometers per second, which is equivalent to the speed that an interstellar missile has not yet been launched, which can only be obtained by burning all the fuel in the past.

However, it is clear that the longer the cable of the space elevator, the higher the requirements for material properties.This kind of thing should be done slowly, not in a hurry.

"Although the deep space civilization has suffered heavy losses, we can't take it lightly. We still have to go all out in all aspects of construction."

"Yes!"

The industrial facilities located in various parts of Sedna have once again entered into a state of full power operation.Up to 16 adults are also working day and night to produce all kinds of materials needed for construction.

Under such circumstances, the first "roller" base was constructed at the fastest speed.It, like the Spark spacecraft, is located in the orbit around Sedna.

After completing the interior decoration and the installation of various equipment, the first batch of residents moved in.And because space was vacated in the Tinder spacecraft, the birth ban on adults was lifted immediately.

Previously, due to the limited capacity of the Ignition spacecraft, there was only a fixed quota of 1000 newborns every six months. People had to control their desire to have children, and they could only give birth after obtaining approval.Otherwise, the Ignition spacecraft will face the pressure of too many people.

Now, with the roller base, this limitation can be lifted.Not only that, Zhao Changxing even started to encourage childbearing immediately.

The more you give birth, the better.There are enough places anyway.The more people are born, the faster the population will grow, and the greater the war potential will be.

After the first roller base was put into operation, the launch pad at the end of the No. [-] space elevator finally launched a new interstellar missile that Zhao Changxing had been looking forward to for a long time.

This time it is not so troublesome.Zhao Changxing didn't even use the method of adding an additional launch pad to launch, and the speed of the missile was completely dependent on the fuel it carried.

Its final speed will only reach more than 20 kilometers per second.But it doesn't matter, Zhao Changxing is sure that the deep space civilization can't even intercept missiles at this speed at this moment.

that's the truth.After more than two months of flying, Zhao Changxing clearly saw 20 gorgeous flowers burst out from the deep space star again.

Of the 20 sub-warheads, none of the deep space civilizations intercepted them.

Now, during this period of time, the facilities that the deep space civilization has painstakingly rebuilt have once again encountered a catastrophe.

"This kind of thing should become a routine." Zhao Changxing set the rules: "With our current production capacity, we can produce enough fissile material to make an atomic bomb a year on average. Then... just launch one missile a year. In any case, the deep space civilization cannot be allowed to enter the normal development path."

One hydrogen bomb a year is enough to turn all the hard work of the deep space civilization into running water during this year.They cannot be built, inhabited, obtained resources, and cannot develop with peace of mind, so they have never been able to become stronger.But our own side has been in the process of rapid development.When your own technology develops enough to build a combat spaceship with practical significance, it will be the end of the game.

At that time, I will send the fleet to visit the deep space star in person, and depending on the situation, either kill them all or capture them all.In short, the deep space civilization cannot be allowed to pose even the slightest threat to human civilization.

At this moment, a huge amount of materials are being transported into space non-stop, and the carbon nanotube production workshop is producing a large amount of high-performance materials that can be used as space elevator cables at all times.The major military factories are going all out to produce weapons of war such as electromagnetic guns, deep space radars, laser cannons, and Wu-1 combat spacecraft. Military industry experts are busy in laboratories and factories, desperately trying to improve the performance of weapons.

Among the many circles of the Tinder spacecraft, the children are slowly growing up.The number of roller bases is slowly increasing, from one at the beginning, to two, to three, to four, to six now.

The completion of each roller base means that the number of minors that can be accommodated has increased by 3000, which means that the average number of new adults produced each year has increased by about 170 compared to the past.

The second space elevator has been successfully completed.Compared with the No. [-] space elevator, it has higher performance. When it is fully loaded, it can transport up to [-] tons of materials into space every day on average.As a result, the construction was further accelerated.

At this moment, it has reached the 255th year of the new calendar.

In the past few years, every year, Zhao Changxing will launch an interstellar missile loaded with 20 sub-warheads to "greeting" to the deep space civilization.Every year, Zhao Changxing can see many newly born buildings turn into dust and return to the world.

One side's development process was abruptly interrupted, while the other side's development process went smoothly.

This is the meaning of that retaliatory action.

During this period of time, the "friendly" communication between the two parties has not been interrupted.Even on each other's major festivals, Zhao Changxing and the leader of the deep space civilization—transliterated, the name is "Nuoli Ruoxi", and the two sides will send greetings to each other.

At least, in the communication between the two sides, such things as war do not exist at all.

This kind of situation will probably not appear on the original earth.Zhao Changxing was also skeptical about this. At least, he couldn't see the point of maintaining the superficial friendship under the premise that the two sides were already at war.Anyway, neither side would trust the other even with a punctuation mark, so Zhao Changxing just played this kind of word game with the other at will.

After another regular launch of an interstellar missile and its successful detonation, some clues from the spy satellite network caught Zhao Changxing's attention.

After the planetary defense system of the deep space civilization has been greatly weakened, the spy satellites of one's own side can also get close to positions that could not be reached before.This has greatly improved the observation effect of one's own side.

It is in this context that spy satellites have photographed what appear to be very suspiciously large shadows on the surface of deep space stars.

After careful identification by relevant experts, mobilization of spy satellites, and risky close detection again, people finally came to a very shocking conclusion.

That is, those shadows are actually not shadows on the surface of the deep space star, but built in space, passing through a specially disguised space base!
Zhao Changxing realized with horror that he had been fooled again.

The deep space civilization should have been determined long ago, and the follow-up nuclear strikes will inevitably continue.The construction of related facilities on the surface of the deep space star is just doing useless work.Therefore, they shifted their focus of development to space early on, trying to complete the development and recovery of civilization in space!
From this point of view, the construction they have carried out on the surface of the deep space star day after day, year after year, seems to be trying to restore the relevant facilities, but in fact it is just paralyzing their own side and covering them in space. The real construction that takes place!

Maybe they really just built some empty shells on the ground, there may be no equipment and facilities inside, and no one lives at all!

Anyway, spy satellites in deep space can't tell the difference between the two.

Maybe when their accumulation reaches a certain level, the revenge action from the deep space civilization will come. At that time, maybe the whole situation will be completely reversed!

Zhao Changxing's expression turned serious like never before.
