- A Brief History of Mankind

......

......

After several long voyages and a faint signal, the Emma fleet finally discovered the edge of the solar system, just as the new year was about to begin.

"Sir, the sensors are not detecting any active signals in the star field."

Inside the flagship in the center of the fleet, Emma's crew, who was in charge of operating the sensors, reported methodically.

Through the portholes, directly in front of the fleet is a shattered planet of death, which is recorded to be the home of the human race, Earth.

Not far away, there is a dark red star called the Sun, which is about to go out.

Around it, several fortresses armed with large cannons are orbiting the stars, like cold tombstones.

These defensive platforms, armed to the teeth, did not react to the arrival of the invaders.

Staring at everything he could see, Karl, the commander of the Emma, understood.

If nothing else, like so many ancient civilizations, the race called humans has most likely disappeared into the long river of history.

What he broke into was just another cold tomb......

Humans, an ancient and mysterious and powerful civilization that exists in legends, are said to be the leaders of the battle for the heavens, the ones who play games with the gods, and the ones who are the unifiers......

In the records of past history, mankind once left countless glorious stories, but such a great civilization disappeared without a trace in almost a night at the most glorious moment.

Some say they hid themselves, others say they have all migrated to another dimension, and according to the teachings of the Emma, humans have been punished by the gods for their arrogance in their bones.

As for the real reason, Carl really has no interest in researching, after all, in the cruel cosmic ecological chain, the rise and fall of civilization is really unremarkable.

- Rise and fall are also the inescapable truths of all living beings.

After just a few moments of waiting, when the last ship sailed into the orbit of the star, Commander Karl gave new instructions to his fleet through the combat channel.

"We're ready to start the recovery operation, and we're going to see what these ghosts have left for us."

With the order given, the destroyers on the side of the fleet took the lead and began to approach the stellar fortresses.

This is a recovery fleet from across the galaxy that belongs to the Emma Empire, and its mission is to unearth the technological templates of lost civilizations.

In the eyes of the Emma, it is better to recycle these technologies to contribute to the cause of the Empire than to throw them into useless garbage in the cold space and become useless garbage.

Over the past thousands of years, it is thanks to the massive discovery of valuable technology from lost civilizations that Emma has been able to build a vast empire that spans half the galaxy in a short period of time.

......

......

As the minutes ticked by, everything seemed to be going more smoothly than expected, as the landing torpedo fired by the destroyer successfully drilled through the outer armor of the stellar fortress and transported the members of the Guardians inside safely.

If nothing else, it won't be long before those precious technical materials will be made into templates by the accompanying technical priests and returned to the fleet.

In order to successfully unearth the mythical technology left behind by humans, the Emma Empire did not hesitate to mobilize the most elite expeditionary fleet in history, and a total of 13 precious Calamity-class battleships were deployed to this recovery fleet.

At this moment, this fleet, which has gathered the top power of the Empire, has been assembled in the orbit of the star.

In the eyes of the veterans of those fleets, such a powerful force may not be easily countered by even the humans of the golden age.

"Captain Karl, when this mission is over, the Empress may be able to canonize a planet to you."

While he waited, a woman's voice came over the communicator Carl was wearing.

"Focus on the task at hand."

Hearing this, the woman on the other end of the communicator smiled.

"You're still as serious and boring as ever, and I don't think anything will happen on this mission."

Karl didn't say a word, looking at the mighty fleet around him, he didn't disagree with such an opinion.

......

......

I don't know how long it was, just when the recycling work was in full swing.

Suddenly, the observer in front of the sensor screamed violently.

"Sir! It's an attack reaction! The sensor shows that there is a build-up of energy nearby! ”

For a moment, everyone in the command room couldn't help but get nervous.

"Attack? Could it be that the fortress's automatic defense system has been activated? ”

Faced with the panic of the adjutants, Captain Karl, who was standing on the bridge, just gave the order unhurriedly.

"Notify the fleet to activate the electromagnetic shield and deploy the combat formation at the same time."

But as soon as his voice fell.

"Look over there!"

Looking in the direction of the voice, people noticed that there seemed to be a flickering light in the distant void, like faint fireflies in the night sky, gradually converging in the asteroid belt formed by the disintegration of the planets.

What is that......

Before Carl realized what was going on.

In the next second, in just half a heartbeat, a string of dark silver beams of light had silently passed through the huge fleet.

In the stunned gaze of everyone, the fused particles burst out with a dazzling light like stars, instantly illuminating this dark ancient cemetery.

Piercing sirens echoed through the cabins of each warship for a long time, and the unparalleled energy of the particles was far deadlier than the arcs of electricity ejected by the Empire's proud Inquisition.

It was only then that the haughty Emma soldiers realized that they were under attack.

The beam didn't last long, and as the light dissipated, the shocked Emma fleet began to quickly go on alert under the orders of their respective commanders.

"Prepare to fight back!"

Historically, when a preemptive attack has worked, the vast majority of enemies will take advantage of the chaos to launch a deadly surprise attack.

However, strangely, as the first round of attacks ended, everything fell silent again, and no enemy was found in the ship's sensors, as if there was a ghost in this space.

Not long after, as the assessment report of the fleet damage entered the command terminal, it was noticed that Captain Karl's face gradually showed such an ugly face.

The report presented by the smart terminal tells an unacceptable fact, and at this moment the right flank of the entire fleet has completely collapsed......

In particular, the Consul-class light aircraft carrier in charge of relay command suffered a catastrophic frontal blow, and after being torn in half by a silver spear of light, it completely lost contact with the fleet.

In the first wave of exploratory attacks alone, it was confirmed that 4 cruisers and 1 logistics aircraft carrier were killed in the sea of stars, and as for the losses of destroyers and the Guardian Army, the computer could not even give accurate statistics for a while.

Everyone was busy, trying to find the attacker in the void in front of them.

"Damn! I can't understand! What the hell is that! ”

Faced with such a huge loss, the technical priest in charge of combat analysis let out a cry of despair.

"Our electromagnetic shield and armor are a piece of paper in front of that thing!"

At about the same moment, in the communication radio filled with the noise of electricity, anxious calls for help were mixed with the continuous sound of gunfire.

Apparently, the Guardian forces inside the fortress were also locked in a bitter battle.

Strangely, according to the image data sent back by the soldiers of the Guardian Army, this elite army of many battles was actually engaged in the same humanoid creature.

Judging from her appearance alone, it was a girl with long gray hair, like a gray shadow walking through the ranks of the Guardian Army.

At the same time, the levitating turret that followed behind it spewed out particle beams with astonishing efficiency, reaping the lives of soldiers.

With her upright features, crimson eyes, and white and smooth skin, the girl had features so similar to those of the Emma, except for the absence of the Emma's signature pointed ears.

Who is she?

Could it be the survivors of human civilization?

But why does she look so similar to Emma?

Looking at the girl on the screen, everyone in the command room couldn't help but feel confused.

At this moment, a voice message from outside the fleet bypassed the fleet's firewall and was forcibly entered into the ship's command computer, playing it in front of everyone.

It was a young male voice who was speaking one of the native languages of the human race, and the meaning of the young human was quickly translated under the decipherment of the accompanying linguists.

......

"On behalf of all of humanity, I inform you that you are not welcome here, grave robbers."
