The last human in the universe

Chapter 124 Exchange Ratio

The so-called metallic hydrogen is actually a special state of existence of hydrogen.

At extremely high pressures—higher than that at the Earth's core—hydrogen turns into a solid that takes on the properties of a metal, as well as superconducting properties.

At the same time, because of its extremely high internal energy, the energy density of metal hydrogen is extremely high, even more than 30 times that of TNT explosives.

Generally speaking, although it can exist stably at room temperature, it is more easily affected and becomes metastable, and even explodes with a bang.

However, if some kind of technology that humans have not yet mastered is adopted to make its existence more stable and controlled, then some very interesting things will happen.

That is, it has the potential to become an explosive and electromagnetic dual reactive armor.

First of all, metal hydrogen has extremely high energy inside.Through some special designs, it may be designed to "explode in a small area in a controlled manner once it is attacked by an external force", and then, through its own explosion, it can explode the external projectile or weaken its kinetic energy.

This is explosive reactive armor.

Second, metallic hydrogen has superconducting properties.This feature can make it have an effect similar to an "electromagnetic coil", actively reducing the speed of foreign metal projectiles through its own electric field.

This is a new type of electromagnetic reactive armor.

In addition, through some special technology, its own form of existence is extremely stable and extremely tough—even far surpassing some special alloys. The superposition of the three makes it have a super high defense that human scientists can hardly imagine.

This is why they can remain unaffected in such a chaotic battlefield.

Li Dajiang looked at the military scientist.

"If it's metallic hydrogen, what do we have to do to break it?"

The scientist's voice trembled slightly: "It can only be consumed. Through its explosive reactive armor characteristics, every projectile that hits it will cause a small part of metal hydrogen to explode, which is equivalent to consuming Part of its armor. If enough projectiles hit it, any amount of metallic hydrogen will be consumed."

"How many pellets do you want?"

"I don't... I don't know. Or, or through high explosives, no, high explosives should not be enough, nuclear bombs, atomic bombs or hydrogen bombs."

At present, human beings simply do not have the ability to project nuclear bombs to accurately hit the enemy in such a chaotic battlefield.

Li Dajiang turned his head and stared at the radar screen, his expression became serious again.

It seems that it is impossible to quickly destroy these enemy spaceships.

But worse is clearly yet to come.

He noticed that the speed at which his spaceship was damaged in battle suddenly increased.

In the past few days, a total of less than 100 combat spaceships were damaged.And the reason for the battle damage is mostly because of bad luck, just happened to be hit by stray bullets.

But now, since the appearance of less than 200 enemy combat spaceships, more than a dozen spaceships have been destroyed in less than an hour!
A picture captured by a spaceship before it was destroyed caught Li Dajiang's attention.

In that picture, there is a small bright spot that is almost invisible.

After zooming in and repairing, Li Dajiang saw the true face of that small bright spot.

That's not a railgun projectile.

It is a missile.

A micro-missile not exceeding 3 centimeters in diameter and 13 centimeters in length.

This kind of missile can't even be called small, it can only be called miniature.

"How can there be such a small missile? Without enough propellant, how can they speed up? If the speed is too slow, how can our spacecraft fail to intercept it?"

But the next moment, Li Dajiang figured it out by himself.

It must be electromagnetic acceleration technology again.

Directly through the electromagnetic gun launcher, just like launching an electromagnetic gun projectile, this kind of miniature missile is launched directly, so that it has an extremely high speed as soon as it appears.

If the small missile launched by the big spacecraft before was actually intercepted because of its size and was destroyed by stray bullets, then this kind of miniature missile has almost no possibility of being intercepted.

As long as I am small enough and fast enough, no stray bullets can hit me.

"Judging from the type of explosion, the warhead of this miniature missile must be loaded with antimatter."

Even if only 0.01 gram of antimatter can be loaded in the warhead of a miniature missile, the energy released by it will be equivalent to the energy released by the simultaneous explosion of hundreds of tons of TNT explosives.

This, no doubt, is enough to destroy a spaceship.

"Not only micro-missiles." The scientist said hoarsely: "There are also ultra-high-speed electromagnetic guns, laser cannons, and electromagnetic pulse bombs..."

Fighting, one's own side can't break through the opponent's defense in a short time.

Can't, can't.Whether it is a micro-missile, an electromagnetic artillery projectile, or a laser cannon, it can easily destroy one's own side.

Run, can't run away.The maneuverability of the enemy's combat spaceship obviously exceeds that of one's own.

Li Dajiang knew very well that at this moment, the big spaceship was still in an extremely weak stage.But, but, even with the enemy in such a weak state, even a little bit of counterattack was unbearable.

Between different levels of civilization, the crushing of strength is so obvious, is it so serious?

If it was the opponent's heyday, how high would the opponent's combat power be?
The situation on the battlefield reversed in such a short period of time.

Li Dajiang looked serious, and slowly issued the latest order.

"From now on, get as close to the opponent as possible, and launch missiles at a shorter distance to attack the opponent."

If the distance is shorter, the possibility of destroying one's own interstellar missiles by stray bullets will be reduced.Although this will also cause the interstellar missiles to be unable to have a higher speed-after all, one's own side does not have electromagnetic acceleration technology, which makes the missiles very easy to be intercepted by the opponent, but let's fight.

Let's fight, this is the last chance of human civilization.

"What kind of spaceship is this?"

At this moment, Li Wenying felt a little hopeless in her heart.

Li Wenying, who was on the front line, had already noticed the unusualness of these spaceships when they first entered the battlefield.

They have too much firepower, too much defense, and ridiculous mobility.

Up to now, only one of this kind of spaceship has been destroyed by a large number of fire from one's own side, but during this period of time, more than 30 spaceships of one's own side have been destroyed by enemy spaceships!
An exchange ratio of more than 30 to [-]!

How is this fight going?
In particular, our own side must continue to maintain pressure on that big spaceship.Once the pressure there is reduced, the enemy is very likely to launch the extremely destructive and extremely high-speed interstellar missiles again, and the laser cannon will also be able to attack freely.

At this time, Li Wenying received an order for close combat.

Close combat, when translated, means taking your life to fill it.

"If there is really no other way, I can only take my life to fill it!"

Li Wenying has no fear of death.He even knows that every soldier has the determination and will to die generously for civilization at any time.

Because human civilization cannot retreat.

"Then fill it with your life!"

At this moment, the combat spacecraft on the side of human civilization showed a more fearless and crazier attitude.

The enemy's spaceship doesn't seem to be well adapted to this fighting rhythm.After changing his style of play, Li Wenying saw through the real-time battle report that three enemy spaceships were destroyed in a short period of time.

This is undoubtedly an extremely high efficiency.

However, he also saw that in the same short period of time, more than 50 spaceships were damaged in battle.

In the spaceship No. 32, looking at the fearless enemy, Yi Luoben felt a little frightened in his heart.

This is different from what is taught in the book...

Everyone is a subhuman, and everyone is carrying out the orders of their superiors. What the superiors say, just do what they want. Why do you have to work so hard?

Just like the commander of the Moyun Litar civilization, he would never issue such desperate orders.Because they know very well that the second person does not have the courage.Even if it is forced to do it, the tactical actions will definitely be deformed.

But now, no matter where it looks from, the enemy is actively implementing this tactic...

It's as if they don't care about their own lives at all, and they are completely willing to die.

Iroben looked at his teacher with some doubts, and saw that Werzben was also full of doubts.

At this moment, the main control room of the Okaro spacecraft.Viragash received a piece of good news.

"Report to the captain! We found that there is something wrong with the vacuum cannon. There is no need to replace spare parts, and it can be restored to normal with simple repairs! It is estimated that in another 3 hours, the vacuum cannon will be repaired!"

This time was several days earlier than expected.

Such good luck made Viragash almost jump up with excitement.

Vacuum Cannon!That is a super weapon developed by countless scientists of our own civilization with great painstaking efforts!

Although the Okaro spaceship is an armed mining ship, not a warship, so the vacuum cannon equipped on it is only a third-line small-equivalent vacuum cannon, but even so, it must be completely enough to deal with these damn local civilizations !
Based on the characteristics of its range attack, one's side doesn't even need to know the coordinates of the enemy's space carrier too accurately to destroy it with one shot!And without the space carrier, how can you fight?
At this moment, Li Wenying's spaceship is still attacking the enemy bravely.However, this impact does not seem to be able to completely reverse the situation.

Although our side has gained a lot of battle results, but our own casualties are too great.

This level of offensive, I am afraid it will not last long, and will be forced to stop.

Until then, until then...

A trace of despair slowly rose in Li Wenying's heart.

He even turned on the radio communication system a little irrationally, and started to shout hoarsely: "You are just subhumans, why are you so loyal to Moyun Litar? Is it fun to be subhumans!"

　The third watch is over. . . .Please count the votes. . .It's getting farther and farther away from the top ten, crying...
