The last human in the universe

Chapter 49 Interception
Zhao Changxing hurried to the defense room and saw the target with his own eyes.

No matter which data you look at, it should be a missile.Its relative speed has reached almost 17.2 kilometers per second at the moment, and it is still improving.At this moment, it is less than 25 kilometers away from the surface of Sedna.

A chill came from Zhao Changxing's back.

Almost without thinking, Zhao Changxing knew that he had been fooled.

Since confirming that there is a high possibility of intelligent life on planet 221SN1, Xiao Xi has been monitoring this planet more closely.Under such circumstances, more information was monitored by Xiao Xi.

It is precisely because of the continuous information transmission that Zhao Changxing thinks that the intelligent life living on that planet should not be aware of its own existence.The reason is simple, if they are aware of their presence, how can they not enforce the maximum radio silence?
Just like myself, when I heard the first message, I decisively executed the maximum radio silence.

But now it seems that this is a strategy they are trying to paralyze themselves.It is very likely that they have discovered their own existence long ago, but in order not to let their own side know, they still let their own side monitor them, and then secretly launched a missile over, trying to achieve the effect of a sneak attack.

This missile may have been flying in space at a low speed for several months-after all, the distance between Sedna and 221SN1 is as high as more than 6000 million kilometers.After approaching the target, the missile immediately started the acceleration action with maximum power, trying to kill the enemy with a thunderous blow before it had time to react!
No, not one!
While thinking quickly in Zhao Changxing's mind, the deep space monitoring network composed of more than 800 ground-based and space-based deep-space radars once again observed the target!
There are five missiles in total!
If the warheads of these five missiles are all loaded with hydrogen bombs—the yield does not need to be too large, 1000 million tons of TNT equivalent is enough, if they hit the Sedna star and detonate successfully...

This is enough to cause earth-shaking changes on Sedna.It is certain that the strong crustal vibration caused by the explosion will destroy all man-made structures on Sedna.

If the design of the three-phase bomb is adopted, that is, the outer layer of the hydrogen bomb is wrapped with a layer of fissile material, then the explosion of the hydrogen bomb will also sprinkle radioactive pollutants on the entire planet.By that time, even if there are still survivors, they will probably be fatally affected by radiation sickness, and it will be impossible to rebuild civilization again!

Without the supplement from the ground, even if the Tinder spacecraft escaped the impact of the violent charged particle flow caused by the hydrogen bomb explosion in space, the tens of thousands of minors living in it would all starve to death.

This is an unquestionable disaster on the level of the end of civilization.

Several members of the War Council hurried over, looking pale and at a loss.

Zhao Changxing looked ashen, but still maintained his composure.

The long journey of life has allowed him to experience too much.This allows him to maintain his composure no matter what the situation.

"Leader, are you going to issue an emergency evacuation order?"

Zhao Changxing shook his head: "It doesn't make sense. There are so many people, there is no place to hide, and there is no time to hide. The only thing we can do is to destroy them. Order, all electromagnetic guns are activated immediately, trying to destroy the target!"

We have railguns!We also have electromagnetic guns, we can't do anything!
Several committee members left in a hurry.Zhao Changxing sits in the combat readiness and defense room, coordinating the overall situation.

Under a slightly flustered operation, it took a full hour for the electromagnetic guns installed in various places on Sedna to be ready.At the same time, because of the angle, only 106 missiles can be intercepted.

For a regular army, such procrastination is unforgivable.But now, Zhao Changxing can't criticize people too much.

"Report to the leader, the No. [-] electromagnetic gun has locked on the No. [-] target!"

"The No. 3 electromagnetic gun has locked on the No. [-] target!"

"We locked on the fifth target!"

During the period of pre-war preparations, the deep space surveillance radar did not discover any new missiles.Of course, this does not mean that there are really no more. It may also be that the performance of the deep space monitoring radar is insufficient, and the number is insufficient, and the fish that slipped through the net have not been found out.But that can't be helped.

"fire!"

Amidst the low humming sound, the tiny projectile with a mass of only 0.5 grams began to accelerate in the vacuum electromagnetic orbit. After 30 seconds, 106 projectiles rushed out of the gun barrel at the same time, and rushed towards the target in space, which was still more than 20 kilometers away from our side.

When aiming at the target, people of course need to consider the amount of advance.In addition, the communication delay caused by the upper limit of the speed of light propagation also needs to be considered.

At their speed, they would encounter the missile, which is seriously suspected to be from planet 221SN1, and hit them in about two hours.

But during this time, people will not choose to wait.

Hitting such a small target at such a long distance is as difficult as reaching the sky.This requires the launch angle of the electromagnetic gun to be accurate to an incredible degree.Now, the electromagnetic guns manufactured by people obviously cannot achieve such accuracy.

Even if the accuracy is sufficient, the trajectory of the electromagnetic gun projectile flying in space also has a certain degree of randomness.Because in space, interstellar dust, planetary gravity, various high-energy radiation, and even high-energy charged particles from the sun will have a slight impact on their trajectories.And once the distance is long enough, the initial small gap will always be magnified to the point where it cannot be ignored.

The interstellar missiles flying towards Star Sedna were no more than 4 meters in diameter and 20 meters in length.A slight deviation, and the target will be missed.

Even Zhao Changxing had to admit that luck was the most important determinant of whether his projectiles could intercept those missiles.

Luck cannot be controlled, so...the key to increasing the success rate lies in quantity.

As long as the number is large enough, no matter how low the probability is, they can always be encountered.

"Lock again, launch again!"

"Continuous launch!"

All 106 electromagnetic guns have entered full power operation mode.In auto lock mode, each time a projectile is fired, the console will immediately initiate a second lock and launch the projectile towards the calculated encounter location.

An electromagnetic gun can fire two projectiles in one minute. 1 units is 106 rounds.And now, the continuous launch has lasted for more than two hours.

A total of nearly [-] projectiles have been shot out.

At this moment, except for a small number of people, people on the entire Sedna planet, including the Pyro spacecraft, are still continuing their previous life trajectories.They are either working, resting, playing, eating or sleeping...

No one can perceive that civilization has fallen into the brink of life and death.

At this moment, the projectile fired for the first time was about to meet those missiles.

But in the radar monitoring network, those missiles still exist.

Obviously, the projectile did not hit the target.

"Don't worry, we still have a chance."

Zhao Changxing comforted the people with a deep voice.

Time passed slowly amid anxiety and heaviness.Suddenly, a "sun" appeared in the dark night sky above Sedna.

The light it released was so bright that it even illuminated the entire land in an instant.People in the wild raised their heads in astonishment, and felt a little stinging in their eyes.

"Target No. [-] is destroyed!"

It exploded tens of thousands of kilometers away from Sedna.At this distance, it will basically have no impact on Sedna.

In the uninterrupted attempts, finally a target was destroyed.But Zhao Changxing's heart became heavier and heavier.

"Judging from the results of the explosion, the warheads of these missiles are indeed loaded with hydrogen bombs! The equivalent is at least 1200 million tons of TNT! There is even a mechanism for destroying when damaged!"

"All missiles must be intercepted, none of them can be hit!"

106 electromagnetic guns are still firing projectiles at full power.And at this moment, there was less than an hour left before they hit Star Sedna.

"Target No. [-] is destroyed!"

The second missile failed to explode.This may be because the damage is too fast and too large, and the damage and destruction mechanism has failed before it can take effect.

"Target No. [-] is destroyed!"

"Target No. [-] is destroyed!"

The destruction of the No. [-] missile and the No. [-] missile once again activated the damaged and destructible device, briefly illuminating the land of Sedna star.

At this moment, all the people who are still awake are aware of something.A feeling of uneasiness is quietly spreading.

At this moment, Zhao Changxing's broadcast reached everyone's ears.

"We have been attacked by enemy missiles. But don't worry, we have the ability to intercept them. Now, everyone stay calm and don't panic."

Zhao Changxing's voice was always so steady, and there was always a reassuring force in it.

In the combat readiness and defense room, a committee member was almost crying at the moment.

"Leader, target No. 20 has not been destroyed yet! In another [-] minutes at most, it will hit us!"

"It has accelerated to the top speed, 25 kilometers per second!"

"The performance of deep-space radar is limited, and there will be errors in searching for such a high-speed target!"

The electromagnetic gun projectile hits the target by luck.Now, the deep-space radar has errors, and the probability of hitting the target is even lower.

Zhao Changxing took a deep breath.

"I order, all flame-type spaceships, all lift off!"

After decades of accumulation, human civilization now has a total of about 200 flame-type space transport ships.Now, they all took off with maximum power, frantically flying toward the trajectory of the missile that was calculated.

At this speed they will quickly run out of fuel.Even if they survived, there is no possibility of people taking them back.

They will rush into deep space without looking back, never to return.
