Cataclysmic Era: I can unlock the tech tree

【Earth】.

The self-splitting detectors of the Cosmic Listening Project sounded an alarm, and the Cleaners dispatched a large fleet from the Peacock-Indian Supercluster to the battlefield.

Thanks to this.

The already busy command center became even busier at this moment.

Orders were issued from the commanding officers and sent towards the main battlefield of the Shapley Supercluster in the distance.

Under these orders, the neutral faction and the fleet of over a hundred billion people from human civilization slowly advanced toward the designated area.

The objective is clear—to cut off the Cleaners' support fleet!

"Beep! Beep! Beep!"

A crisp notification sound rang out, and at the same time, a bright red icon automatically popped up in the upper right corner of the holographic projection.

"Nus?" Zhao Zijie frowned slightly.

The current [Nus] and its subordinate Zerg are a trump card in the hands of human civilization.

Anyone can get into trouble, but these things can't!

Therefore, Zhao Zijie quickly put down his work and reached out to open the warning information.

"This is……"

Looking at the image in the holographic projection, Zhao Zijie's eyes widened in disbelief.

Although he didn't know the specific purpose and working principle of the giant structures in the picture, the spectacular scene of their internal structures unfolding still gave rise to a terrible thought in his mind.

problem occurs!

What kind of trouble is the sanitation workers causing now?!

"Quickly! Notify Professor Lü!"

Zhao Zijie suddenly stood up from his seat and shouted urgently.

……

More than ten seconds later.

Countless fluorescent green dots of light pierced through the tightly closed doors of the command center, and then coalesced into a human figure under everyone's accustomed gaze.

"Professor..." Upon seeing the person who arrived, Zhao Zijie subconsciously breathed a sigh of relief. "Nus has sent a warning message: the Cleaners..."

"The Cleaners are preparing to launch the Universe Acceleration Project!"

Before the quantum-state figure had fully solidified, Lü Yongchang's voice rang out in the command center.

"The Ring Universe Acceleration Project..." Zhao Zijie paused slightly, "Weren't many of the accelerator nodes in the Laniakea Supercluster destroyed by the 'Pastoral Faction'?"

Lu Yongchang's figure had completely solidified, and he said in a heavy tone, "This is the problem."

"The Cleaners must have learned some information, otherwise they would never have activated the ring-space acceleration device so hastily!"

Every particle acceleration experiment requires a great deal of preparation.

Let alone cosmic particle accelerator experiments, even planetary and stellar particle accelerator experiments cannot be started on a whim!

Could it be that the five-dimensional beings of the pastoral school are making some kind of move?

The thought had barely crossed Lü Yongchang's mind when a piercing alarm blared in the command center.

A deep blue holographic projection automatically unfolded in front of him, rapidly updating countless complex parameters.

Although he couldn't understand the complex data, Zhao Zijie still identified the source of the holographic projection—the All-Weather Local Bubble Monitoring Unit.

To put it bluntly, it's an ultra-long-distance monitoring device for the five-dimensional creatures of the pastoral region.

Looking at the image projected on the screen, Lü Yongchang's face instantly darkened.

"professor?"

A rare hint of panic flashed in Lü Yongchang's eyes: "The five-dimensional beings of the Pastoral School have disappeared!"

"Disappeared? How could such a large five-dimensional being simply vanish into thin air?"

"The 24/7 Local Bubble Monitoring Unit, as the name suggests, can only monitor the local bubble."

"Now, there's no trace of it on the monitoring equipment."

"There's only one possibility," Lü Yongchang concluded, emphasizing each word: "It has already left this cosmic bubble!!"

Zhao Zijie was stunned and stood there.

Leaving this universe...

Lu Yongchang paced back and forth in the command center, somewhat agitated.

He could guess the five-dimensional being's intentions without even having to think!

A high-dimensional attack was launched against the combined fleet of humans and neutral factions from the fifth-dimensional space outside the cosmic bubble!

This is a true high-dimensional attack!

"Damn it, I should have known! How could five-dimensional beings not have mastered five-dimensional travel technology!"

He muttered to himself, "This is bad. We haven't yet mastered the means to observe the five-dimensional space outside this universe..."

Zhao Zijie silently watched the flashing warning signs in the holographic projection, then hesitantly asked Lü Yongchang, "Professor, what about the Cleaner's Ring Universe Acceleration Project...?"

"Should we interfere with it?"

What time is it? The five-dimensional beings of the pastoral faction are already preparing to make their move, why are you still bothering with the cleaners?!

Just as Lü Yongchang was about to ask Zhao Zijie a question, a sudden inspiration flashed through his mind.

No.

still have a chance!

The cleaner! Still the cleaner!

"No! We must not interfere with the Cleaners' Cosmic Acceleration Project!"

Lu Yongchang whirled around, staring intently at the holographic projection in front of him: "Currently, only the Cleaners' Ring Universe Acceleration Project can attract the attention of that five-dimensional being!"

Before the words had even finished,

Another warning popped up in the holographic projection.

"warn!"

Zero's synthesized electronic voice rang in everyone's ears: "Abnormal fluctuations in spacetime curvature have been detected in the Boötes Void region and the Shapley Supercluster region."

Lu Yongchang's expression changed completely after just one glance at the data on the projector.

If the original spacetime was a flat sea surface, then the current spacetime ocean has become an upward-convex curved surface!

A massive object is approaching the cosmic bubble!

A pastoral five-dimensional being!

He has come!

"zero!"

With eyes wide with rage, Lü Yongchang stared at the increasingly violent fluctuations in spacetime curvature on the holographic projection, and shouted at the top of his lungs, "Forcefully seize control of all friendly warships!"

"Cease all existing attack plans!"

"Upgrade to a higher dimension! Upgrade to a higher dimension immediately!"

"Running the dark matter stable field at full power!!!"

……

Outside the bubble of this universe.

Within the bizarre and fantastical five-dimensional space, the membrane slowly swayed its body.

After all, He was not a native five-dimensional being, so navigating in five-dimensional space was not an easy task.

Especially after billions of years of "house arrest," His already not-so-skilled five-dimensional navigation technology became even more rudimentary.

He painstakingly adjusted his movements to ensure that he was on the right course.

The consequences of a calculation error are very serious—it may unknowingly drift away from this cosmic bubble, and may never be able to find its way home!

His gaze swept quickly across the cosmic bubble beneath him, and each galaxy appeared as insignificant as grains of sand in his eyes.

found it.

He gazed at the vast, empty area where the spatial and temporal fluctuations were exceptionally intense, a faint smile appearing in his eyes.

The Boötes Void, the base of human civilization.

And the Shapley Supercluster, the main battlefield.

The combined fleet, composed of the Cleaners and the Pastoralists, has begun to gradually withdraw, but with such a large-scale attack, friendly fire is inevitable.

Sometimes, necessary sacrifices are unavoidable in order to achieve victory.

This applies to war, and it also applies to the continuation of civilization.

With that thought in mind, He aimed at His target and launched a spatial weapon from the fifth dimension.
