Cataclysmic Era: I can unlock the tech tree

Rewind to a dozen minutes earlier, to the moment when the war droid first set foot on Enrogett's flagship.

In order to break through the enemy's interception facilities, the war robots raised their cannons and launched extremely fierce attacks on the target.

Just as the attention of the Enroget command center was completely drawn, specially made projectiles were blasted into the decks and various devices of the warship amidst the artillery fire.

No one noticed that these silvery-white projectiles did not explode violently upon impact with their targets, but instead quickly "melted," like a pool of silvery-white liquid seeping into various crevices.

This is the latest research achievement of the Chinese Academy of Sciences—a nano-invasive device.

From the original design concept, they should have been mounted on warp missiles to launch intrusions into enemy computer systems through ultra-long-range attacks.

However, the situation in actual combat is far too complex.

On the one hand, with the help of various composite shields and interceptor weapons, warp missiles have a hard time getting close to enemy warships.

On the other hand, the enemy can physically cut off the communication links of the invaded warships at any time to intercept Zero's invasion. Premature attacks will not only fail to achieve the desired effect, but may even alert the enemy.

Therefore, it was ultimately used in interstellar boarding battles to seize control of the flagship.

These silvery-white projectiles are composed of a large number of specially modified nanobots—which have greater endurance and mobility.

In the salvo just now, each war robot fired an average of more than ten of these specially made projectiles.

A massive number of nanobots launched a saturation attack on the flagship from all angles and directions, from unknown corners.

Openly repair the plank road while secretly crossing the Chencang pass!

When some of the nanorobots successfully made contact with the tachyon communication device...

This war has now come to a complete end.

……

The expected image did not appear on the screen in front of it.

The massive flagship that should have crashed in the flames of the antimatter reactor explosion is still gliding safely through space.

At the same time, the red dots representing the invaders suddenly increased their speed several times over.

Those defensive structures were practically useless, failing to provide any real protection.

These war machines, like sharp swords, plunged straight into the core area of ​​the flagship!

The old scientist's eyes widened suddenly, and he subconsciously raised his hand to press the physical button in front of him again.

Click, click, click...

The familiar damping sensation was felt, but no unusual changes occurred.

Is the button broken?

The old scientist stared in disbelief at the dark blue button in front of him.

Are you kidding me?

How could a physical button that concerns the life and death of a Level 5 civilization just break down like that?!

Just as it was somewhat at a loss, a line of Enrogett text slowly appeared in the center of all the screens.

【Hello. 】

This is human civilization.

The noisy exchanges in the command center vanished instantly at that moment.

……

blank.

My mind went completely blank.

The old scientist stared blankly at the two lines of text on the screen.

After a long while, its stagnant thoughts finally began to function again.

Like an old starship that has been parked for thousands of years, its thinking organs took a considerable amount of time and effort to arrive at a conclusion from these two simple lines of text.

The central computer of the civilization has been hacked.

Then, like an erupting volcano, countless questions burst forth from its heart.

When did this happen?

Why was there no warning? Why was there no alert? Why...?

Suddenly, as if it had thought of something, it abruptly turned its head to look at a screen beside it.

Swish!

Its body went limp and it collapsed onto the seat behind it.

Synchronous orbit tachyon communication transmitter

The email sending task has been forcibly stopped.

Current loop count: 0

【…】

The message was not sent.

Its expression was somewhat distorted, as if it was enduring some kind of pain.

The elderly scientist struggled to his feet and glanced once more at the core, top-secret documents on the central computer.

It breathed a long sigh of relief.

It raised its hand, clutching its chest, its eyes filled with pain.

On the screen in front of the command center,

The more than two thousand warships acting as nodes have stopped their warp drives and are slowly sailing towards the Enrogette system in a neat formation.

At the very front of the fleet was the massive "flagship".

The once turbulent ocean of time and space gradually returned to calm.

The dense array of red dots indicates that they have entered the core area of ​​the flagship, the Enroget.

Beside the human fleet, one after another, Enrogate warships uncontrollably ceased their attacks, and then, amidst gasps of astonishment, "voluntarily" joined the human civilization's fleet...

It slowly closed its eyes.

A few seconds later, its pained expression suddenly relaxed, and the arm that had been clutching its chest fell down uncontrollably.

Inside the command center, chaos reigned.

No matter what orders the alliance leader gave, the commanders facing certain death ran around like headless flies.

Only the elderly scientist Enrogett, whose body was covered in wrinkles, remained quietly seated in his chair.

His droopy eyelids opened slightly, and his lifeless eyes seemed to be staring at the chaotic command center, or perhaps gazing at the setting sun of the Enroget civilization.

It's dead.

Nobody noticed.

……

Within the Kepler 452 galaxy.

In the deep blue holographic projection, lines of luminous white text appeared.

At the same time, the electronic synthesized sound of zero also rang out.

"Control of the central computer has been successfully seized."

The smile that had just appeared on Lü Yongchang's face vanished completely in the next second.

"warn!"

"An unknown Type I potential threat has been detected, and attempts are underway to intercept it..."

The originally azure blue holographic image instantly turned blood red.

Upon hearing this message, Lü Yongchang's expression changed drastically.

He completely changed his previous calm demeanor and stood up from the chair!

Type I potential threats, in the classification of the Sociology Department, are the highest level of potential threats to human civilization.

Normally, such alerts are only triggered by contact with unknown advanced civilizations.

That's why Lü Yongchang's heart was pounding in his throat.

Could there be an even higher level of civilization behind this Level 5 civilization?!

"The email sending process has been forcibly stopped."

"Current message sending count: 0."

Soon, Zero's synthesized voice rang out again.

Lü Yongchang let out a long sigh of relief.

This slightly stiff electronic synthesized voice actually brought him an unprecedented sense of security!

"Zero, what's going on?"

Lu Yongchang sat back in his chair and asked Zero in a deep voice, "What was the content of the message? And who was the target?"
