Chapter 14: A star-destroying cannon with a power of 17.5 billion

Darkness.

This is the background color of the universe.

Empty.

This is the theme song of the universe.

The birth and destruction of anything are just embellishments on this black cloth.

After what happened more than 700 years ago, the entire geothermal civilization began to tighten its defenses. They have been waiting for the enemy to attack.

But after waiting for so long, the enemy still did not come, which made their defense change from the original full-out to twos and threes.

From space, there are only dozens of spaceships patrolling around the entire planet.

There are still a few ships farther away from the planet as advance defense.

This is the inertia of living things.

It comes from the most basic logic of energy consumption.

As long as living things tend to save body energy, inertia will exist.

The entire planet is much brighter than it was nearly a thousand years ago, and more buildings have sprung up on the planet, and they are even no longer dependent on volcanoes.

This is also thanks to the absolute zero missile.

This civilization passively got rid of its dependence on geothermal energy in a few hundred years and switched to nuclear power generation.

External threats are the best ladder for the progress of civilization.

This statement is indeed true.

The reason why humans can develop so fast is also because of the characteristics of human civilization - endless wars.

The history of human civilization is also the history of human wars!

Just when all creatures on the planet were slack because of hundreds of years of stability.

A beam of light lit up from a distance and hit a giant crystal ball on the ground.

After the crystal ball was hit by the beam, the internal structure immediately dispersed the light evenly, turning the entire crystal ball into a huge light bulb.

The light emitted by the crystal ball can be seen within hundreds of kilometers around.

Suddenly.

Chaos arose.

Countless warships began to prepare for takeoff.

The light shot out from the surface of the planet into space.

The civilization determined the enemy's position and distance in almost half an hour through the light.

Tens of thousands of turrets on the ground began to turn.

The planet itself has no atmosphere, so their weapons can be fired directly on the ground.

And because it is a laser weapon, there is no need to consider the influence of gravity, which allows them to use the entire planet as a fortress.

They adjusted their positions and then began to attack in almost ten minutes.

Beams of light rose into the sky, each with a diameter of more than 20 meters and a length of 700 meters, like huge lightsabers, making it difficult to tell whether it was technology or magic.

…

In the starry sky.

The spacecraft, like a cruising beast, spread out in a fan-shaped manner.

In the front were the cruisers and destroyers.

Laser weapons themselves are light, and light is the fastest speed in the universe to reach the physical limit. Perfect optical weapons can only be discovered after they arrive, just like gamma rays.

So from the front, Yan Xia could not find the opponent's laser.

Only when the opponent's laser hits him can he sense that the opponent has launched an attack, and thus avoid it by predicting his own position.

This is the bug of the laser weapon.

Fortunately, the distance between the two sides is far enough at this time.

When the first laser passed 40,000 kilometers from the side of a destroyer, the photons emitted were captured by Ella.

"The enemy has launched an attack."

"And the scale will not be small."

Yan Xia nodded, because in just two sentences, hundreds of lasers had already flown past them.

At the same time, their two warships were hit.

"Fully deploy the electromagnetic shield."

Many things in light, electricity, magnetism and chemistry belong to the category of electromagnetics.

Laser weapons can be blocked by magnetic fields.

The destroyers began to approach.

When the distance between each destroyer was less than 100 kilometers, the electromagnetic shield was deployed.

Magnetic force itself has the characteristic of mutual attraction. Ella took advantage of this characteristic. The electromagnetic shields deployed by the destroyers can be connected to each other at this distance, like iron chains connecting boats.

Yan Xia looked outside from the main ship and felt that the destroyers were just a little closer.

The electromagnetic shield does not flash with electric light like in the movie. This special shield can only be seen on the instrument.

About ten seconds after the electromagnetic shield was deployed, a beam of laser hit the electromagnetic shield.

According to common sense, light is not affected by magnetic fields, but what Yan Xia observed was that the electromagnetic shield lit up and turned into a visible electric grid.

"What's going on?"

Ella explained: "The electromagnetic shield does not block lasers with the magnetic field itself, but with the photoelectric effect and Delbrück scattering."

"Many electrons and special atomic nuclei are released in the electromagnetic shield. Electrons can be evenly distributed on the electromagnetic shield under the influence of magnetic force. Although magnetic force cannot block photons, electrons can. The electric field generated by atomic nuclei can also interfere with the operation of photons."

The entire electromagnetic shield, which is hundreds of kilometers long, lit up.

The fleet moved forward with such a light shield.

They are now only 3 astronomical units away from the enemy planet. At the speed of the first fleet, it only takes 5 days to approach the enemy planet.

"Since the enemy has welcomed us, we should also give them a gift."

Yan Xia issued an order, ordering the battleships and cruisers to launch absolute zero missiles.

In space, they are not affected by gravity and air resistance, and high-speed shells can be superimposed with the speed of the spacecraft itself.

The missile successfully reached the outer space of the enemy planet three days after launch.

The triggering method of the small absolute zero missile is different from the previous one. When the ambient temperature rises to -100 degrees Celsius or hits an object, it will automatically detonate.

A huge number of laser weapons are aimed at the incoming missiles.

A silent explosion bloomed in the starry sky.

The terrifying coldness instantly spread in the outer space of the planet, and everything within 260 kilometers of the explosion.

Several alien warships were covered by the coldness, and the entire spacecraft lost power and fell towards the surface of the planet.

But it was pulled up instantly when it was still 10 kilometers from the ground.

As Ella said, this civilization has done research and prevention against absolute zero weapons.

However, these weapons themselves are just to buy enough time for the fleet.

The fleet has arrived within the range that the instrument can detect.

The distance between the two sides is less than 1.4 astronomical units.

"This distance should be appropriate." Yan Xia asked in the spacecraft.

Ella nodded.

"That's right."

"Then charge and fire..."

The huge antimatter star destroyer was placed in front of the Hope, with a total length of 1,152 meters, which is close to half the length of the Hope.

The huge sphere behind the cannon is an antimatter manufacturing machine.

The machine uses lasers to hit gold to generate 6 billion degrees of high temperature to produce positive and negative electrons, and stores positrons in a magnetic field.

During the charging process, the electromagnetic thrusters stopped firing, and all controlled nuclear fusion devices powered the antimatter star destroyer.

After about 10 hours of charging.

"Antimatter charging is complete, the charging amount is 408kg."

"Fire!"

The 408kg of antimatter was gathered and ejected by the huge cannon barrel, without shape or color.

It was like a ball of gas.

Civilizations that have not mastered antimatter technology cannot even observe its existence.

These substances hit the surface of the target planet 7.5 hours later at 1/40 of the speed of light.

The alien civilization annihilated the antimatter and the matter on the surface of the planet without any reaction.

"BOOM!!!!"

The horrific explosion reached 17.5 billion tons equivalent, which is 350 times the energy released by the largest hydrogen bomb "Tsar" ever detonated in human history.

The core radius of the explosion reached 100 kilometers.

In an instant.

The entire hemisphere of the planet was swallowed by light, and the heat could be felt 2,000 kilometers away.

Without air resistance, the shock wave composed of dust and gravel spread to the entire surface of the planet at 10 times the speed of sound within an hour and a half, destroying countless buildings.

Seeing this scene.

The alien spacecraft still in outer space even stopped moving, silently watching the surface of their home planet being destroyed without any warning.
