Cataclysmic Era: I can unlock the tech tree

【warn! 】

All shipborne drones are now offline!

The Zero Point Furnace is now operating at overcapacity!

The dark matter stable field generator has entered an overload state!

【…】

In the holographic projection, lines of blood-red warning messages flashed incessantly.

With the energy supply from a large number of dimensional beings, the assimilation power of the two-dimensional giant star painting gradually exceeded the output power of the dark matter stable field!

The two-dimensional starry sky is gradually moving towards the center.

The outermost swarm of shipborne drones has long since become twisted lines.

At this very moment, the dimensional reduction attack has reached the conventional warships of the outermost layer!

Firepower support from the rear of the human fleet was unlikely to have much effect on this colossal scene spanning a hundred light-years in space; it could only slightly slow its spread.

……

On the other side, the Tenth Empire and the Neutral Front war zone.

"Human civilization's flagship is facing a crisis!!!"

Intense electromagnetic waves echoed within the Tenth Empire's massive flagship: "Support! We must support human civilization!"

The emperor's expression darkened slightly, and he quickly made a decision: "...There's no time to worry about that! Suppress the enemy with firepower, attempt to disengage from the battlefield, and support human civilization!"

The moment the order was given, the Imperial fleet unleashed several salvos in an attempt to suppress the relentless onslaught of dimensional creatures.

The effect was not significant.

These pastoral reinforcements clearly saw through the Tenth Empire's intentions. Braving the firepower of the Imperial fleet, they risked their lives to hinder the Empire's return reinforcements!

The chaotic battle situation made the emperor increasingly anxious.

Faced with such a massive dimensional reduction attack, no one knows how long human civilization can hold out!

He turned his gaze to the edge of the void in the constellation Boötes.

The neutral reinforcements will take quite some time to arrive.

In the present-day void of Boötes, it seems that only one force remains that can help human civilization!

"The cleaners..."

The emperor murmured to himself, turning his gaze toward the Sweeper fleet.

The Sweeper fleet seemed to be shocked by the scene and was still slowly retreating—in their memory, the Pastoral Faction had never fought so desperately!

Suddenly, as if struck by a sudden realization, the Emperor unleashed a powerful electromagnetic wave: "The Cleaners! The Cleaners!"

"Quickly! Send a radio broadcast to the sanitation workers!"

"Tell them the true identity and purpose of the pastoralists!"

The emperor believed that no civilization wanted its universe to perish!

To stand by and watch?

The fire has already reached his own doorstep; he doesn't believe the cleaner can remain calm!

A powerful tachyon signal roared toward the Sweeper fleet.

It adopts a universal frequency band and a universal resolution method, and also comes with a self-decoding system.

There is no doubt that pastoral civilizations can also receive this message.

But at this moment, the Tenth Empire could not care about so much. Only by dragging the Cleaners civilization into the battlefield could there be a chance to turn the tide of the war!

……

The bottom region of the cosmic bubble.

[Membrane] Gazing at the emptiness of Boötes and the flagship of human civilization mired in the quagmire, He breathed a slight sigh of relief.

A dimensional reduction attack spanning a hundred light-years...

As far as I can remember, this was the first time the pastoral faction had used a dimensional reduction attack of this scale.

That flagship is doomed.

He thought to himself silently, while turning his attention back to the tough hyperspace membrane.

Soon, we'll be able to break down this barrier!

Annihilation Plan...

A powerful radio broadcast suddenly came, interrupting His thoughts.

【…】

After a brief silence, the five-dimensional space around Him began to tremble violently!

Damn it! Damn it!!

How could the Annihilation Project have been exposed?! How did the Tenth Empire know our identities?!

[A four-dimensional void? Could it be that the remnants of a mother civilization still exist within a four-dimensional void?!]

Damn it!!

Stop the Tenth Empire immediately!!

……

Soon, the cleaners' civilized response came rushing in on the same frequency.

I need evidence.

The response was simple: the Sweeper fleet did not stop its retreat.

Clearly, they did not believe the message from the Tenth Empire.

[Zero-point vacuum energy! The massive extraction of zero-point vacuum energy would deprive the universe of its energy for expansion, leading to its collapse!]

The Pastoral Faction's annihilation plan involves causing an annihilation reaction between the positive and negative universes to obtain the energy to replenish the deficit and reshape the universe!

The Tenth Empire quickly sent out a message, even attaching a diagram of the anti-cosmic microwave background radiation drawn by Lü Yongchang.

But the Sweeper fleet did not stop retreating.

The hidden dangers of vacuum zero-point energy are something that civilization has long been clearly aware of.

The reason we built the Cosmic Accelerator was to escape this inevitable catastrophe.

[Your anti-universe theory... is indeed a novel theory, and our Academy of Sciences will establish it as a new research project.]

However, none of this is sufficient to prove that the Pastoral Faction comes from another universe, much less to prove their annihilation plan.

The emperor looked at the information before him and couldn't help but feel a little tired.

As the Cleaner Civilization said, this is also the fundamental reason why the fifth Supreme Conference of the Pastoral Faction has not yet yielded any results!

The dimensional creatures of the pastoral faction launched an even more ferocious offensive, displaying a desperate ferocity reminiscent of their attacks on human fleets.

A large number of dimensional creatures gathered and attacked the Tenth Empire's fleet—clearly, they did not want the Tenth Empire to continue speaking!

This scene, ironically, caused the Sweeper fleet to stop its retreat.

At that moment, a tachyon signal came from the human war zone.

[Civilized cleaning is the essence of human civilization.]

Our flagship contains evidence that proves everything.

As you all probably know, the leader of the pastoral faction has never appeared so far.

Its predecessor was the Trojan civilization from another universe.

According to the interpretation of the Academy of Human Civilization, we believe it has reached the threshold of a Level 9 civilization.

Currently, it should be a five-dimensional being.

I'll never rest until I say something shocking!

The tachyon message emitted by human civilization shocked the entire battlefield!

Do not!

It's the entire universe!

Needless to say, the reaction of the pastoral faction was that a large number of dimensional creatures abandoned their attacks on the neutral faction and the Tenth Empire's fleet, and turned to rush towards the flagship of human civilization!

This scene was like the last straw that broke the camel's back, directly dispelling the last bit of doubt in the cleaner's mind.

hum!

The fluctuations of the four-dimensional leap instantly appeared on the battlefield, and the Quark Fortress and Black Hole Fortress of the Sweeper Civilization disappeared into the visible universe in one fell swoop!

When they reappeared, they were already near the human war zone!

Human civilization!

I hope you can provide sufficiently convincing evidence!

P.S.: Thanks to Little Moss for the expert certification!

Thank you sir!!

Regarding the updates over the past few days.

The ending is indeed difficult to write. I've been working on the plot for the past few days, so updates may be less frequent.

Once the final plot points are sorted out (and I've figured out how to fill in the plot holes), I'll be able to update more frequently.

Think about it from another perspective, you wouldn't want to experience writer's block during the finale, would you?
