The last human in the universe

Chapter 77 Landmines
This is a new type of weapon that no one has ever thought of before, and no one has used it.But Cheng Kaitian believes that, at least in terms of technology and resources, it is not difficult to manufacture such weapons.

The name of this weapon, Cheng Kaitian named it, Interstellar Mine.

To put it bluntly, this kind of weapon is just a spherical bomb with a charge of tens of grams, mixed with some aluminum powder and projectiles.With the performance of the explosives currently used, such a bomb can release about 300KJ of energy when it explodes.

The power of a single interstellar mine is not that great.But what if... there were 100 of these mines? 1000 million, [-] million, or even [-] million?

If it is possible to put a full [-] million interstellar landmines roughly around the space base of the deep space civilization, make them orbit the deep space star together with the space base of the deep space civilization, and then set up collision and explosion devices for these landmines, So, what will happen?
This kind of thing makes Zhao Changxing feel very interesting when he thinks about it.

There are too many interstellar mines, and it is unrealistic to destroy them one by one.Moreover, even if they are destroyed, their explosion will release a larger amount of "space junk", making the space environment more chaotic.

Their orbits are unstable, which means they don't behave properly.Some of them may be far away from the bases of deep space civilizations, and of course some of them will be close to these bases.And once you get close to the base, the crash-and-explode device will work, and there will be a bang.

The most wonderful thing is that once surrounded by interstellar mine clusters, all space bases of deep space civilization will lose all mobility.Because no matter whether they accelerate or decelerate, they will only hit more interstellar mines, detonate more interstellar mines, and make themselves perish faster.

And what people need to do is just to create a sufficient number of interstellar mines, then aim them in the general direction, and throw them all over.

Yes, it's that simple!
There is no need for remote control, no mutual coordination, no defensive means, and no high speed. It is enough to directly let them occupy the space near the space bases of all deep space civilizations!

Among the three requirements of power, speed, and accuracy, the two requirements of speed and accuracy can be ignored.Because Starmine doesn't need those two.And the power is completely enough.

From this point of view, in the overall strategic system formulated by Zhao Changxing and the members of the war committee, this weapon can completely replace the ecological niche of the combat spaceship in the system!

It should be pointed out that Zhao Changxing originally planned to create a sufficient number of interstellar mines to occupy all the near-earth surrounding space around the deep space star.In this way, there is no need for the previous aiming launch, just like dumping garbage, pouring it into the deep space star and it's over.

But after simple calculations, Zhao Changxing had to give up this plan, and instead adopted the mode of only dropping clusters of interstellar mines around the space base of the deep space civilization.

On the deep space star, the bases of the deep space civilization are probably all gathered within a range of 70-90 kilometers from the surface.The space in this range has a total volume of about 4000 million cubic kilometers.Based on the density of one interstellar mine per cubic meter, then a full 4 billion interstellar mines are needed.If the mass of an interstellar mine is 100 grams, it needs a full 4 trillion tons of materials.

The mass of the entire space carrier is only on the order of more than 1000 million tons.

There is no way but to adopt the second best solution.However, this plan must also be able to achieve results.

Under Zhao Changxing's call, everyone in the space carrier was put into front-line production.

The space dock and machinery factory roared endlessly all day long.Everyone in the space carrier is in a hurry.

The current life reminds Zhao Changxing of some assembly line factories long, long ago, when the earth was still a country.

Zhao Changxing feels that he has now become a piece-rate worker in an assembly line factory.

"How many did you make today?"

"Seven, how about you?"

"Hey, I'm still not familiar with the process, so I only made 56 of them."

"You are too slow, Xiao Li made more than 300 today!"

"More than 300! Is this still human?"

"Today's mobile red flag must belong to Xiao Li."

"I heard that if you get a mobile red flag once, you are eligible for third-class merit? If you have won more times, you will still be awarded second-class merit?"

"It seems to be, the leader seems to be discussing with the commanders."

"Then we have to work hard."

Discussions like this are everywhere in the space carrier.

When this war comes to an end and human beings win—if they can win, then everyone who participated in this war, no matter the front-line soldiers or logistics soldiers, can be sure to be real human heroes.After returning to Star Sedna, not only the supreme honor, but also a series of material rewards, such as contribution points, housing and so on.

If you choose the best from the best, there are four levels: third-class work, second-class work, first-class work, and special work.On the basis of the previous honorary title of "Human Hero", more honors and rewards will be obtained.Especially the special merits, which are destined to be written into the history books for future generations to pass on.

I dare not think about special merit, but if the piecework production in the assembly line is done well, and there is hope to get third-class and second-class merit, then the temptation is too great.

Nothing to say, it's over.

In the midst of being busy all day long, even Zhao Changxing was fighting on the front line and got a mobile red flag, everyone's enthusiasm for production was mobilized.The data of the highest single-person output in a single day has also been repeatedly refreshed.When the production finally ended, this number was even refreshed to more than 1.5.

Of course, there are various factors such as process optimization, greatly improved automation, and familiarity with production, but the figure of 1.5 still surprised most people, and was regarded as a god-man for a while.

During the production period of more than 400 days, excluding those soldiers who had already sacrificed, the remaining more than [-] people produced a total of about [-] million space mines.At this moment, they are all stored in the warehouse.

At this point, all one needs to do is the last step.That is, drop these interstellar mines near the target.

In the delivery method, Zhao Changxing and the committee members conducted a detailed and thorough demonstration again, and finally decided to adopt the plan of moving the space carrier forward again, and then relying on the combat spacecraft to complete the final step of delivery.

This scheme is basically the only feasible scheme that can be adopted at this stage.

When launching, the combat spaceship will accelerate itself to a suitable speed and direction, then immediately brake to slow down, and at the same time open the door of the ammunition compartment, so, under the action of inertia, the interstellar landmines will move on their own Get out, and finally enter the orbit around the deep space star.

A combat spacecraft can carry about 50 tons of mass at a time, which is about 50 interstellar mines.At this moment, there are still 12 combat spaceships left, each of which needs to fly about 30 times in total to complete the entire launch.

After finalizing the launch plan, the space carrier began to maneuver again.

Its main engine and attitude adjustment engine once again entered the full-power operation mode, propelling the huge and cumbersome space carrier, although it has been greatly reduced in size, to start moving towards the predetermined location.

Just when the maneuver had been going on for several days and was about to complete halfway, Zhao Changxing once again felt the vibration he had felt before.This made his brow wrinkle again.

A support staff from the engineering team rushed in.

"Leader, the main axis of the Helicarrier has suffered unexpected damage again! If you continue to accelerate, the support shaft of the circle layer may break!"

Ok? !

Everyone became tense.Everyone's eyes once again focused on Zhao Changxing.

People understand very well that if the acceleration of the space carrier is stopped now, although it is also possible to use combat spacecraft to deliver interstellar mines, this will greatly prolong the time interval between different batches of delivery, and this may cause affect the overall combat effectiveness.

But continue to accelerate, what if the supporting shaft of the spaceship's circle is really broken?
Zhao Changxing thought quickly, weighing the pros and cons quickly.

"Keep accelerating!" Zhao Changxing jumped up, "Everyone put on space suits, and prepare for the rupture of the support shaft of the ring layer and subsequent disasters! The emergency repair team will come to me immediately!"

Between ensuring combat effectiveness and ensuring the safety of the space carrier, Zhao Changxing chose the former.

The significance of this war is too great, Zhao Changxing does not allow anything to delay him.

It is necessary to ensure that the release time interval is within the range, even if the space carrier is damaged.Anyway, if the war fails, people like myself will not be able to escape!
The only thing that needs to be prayed now is that the main axis and support shaft of the space carrier can be supported and not broken before maneuvering to the predetermined location.When the maneuver reaches the target, love can be as bad as it is!
People put on spacesuits as quickly as possible, prepared to withstand the follow-up disaster, and began to pray in silence that the space carrier could survive this time.

Time passed slowly in the heavy.During this period of time, at regular intervals, people could hear the sound of thumping and breaking that seemed to indicate an ominous sign.It wasn't until several days later that the maneuver was over that people were relieved.

The scheduled location has been reached, and follow-up delivery can be carried out.

At this time, the engineering team found Zhao Changxing again.

"Leader, the cause of the main shaft problem has been found out! This is a quality problem! Several properties of the special steel that make up the main shaft are three thousandths worse than the requirements in the planning drawings! This is a man-made disaster!"

The engineering team member gritted his teeth, full of anger.

"boom!"

Zhao Changxing stood up against the table, his expression was as cold as ice.

　Today is also the fourth update!
