Cataclysmic Era: I can unlock the tech tree

"The second batch of electromagnetic railgun projectiles is about to hit the enemy ship's shields!"

"Projectile survival rate: 9.13%!"

"The third batch of electromagnetic railgun projectiles..."

Survival rate: 15.76%!

"The fourth batch..."

Inside the command center of the Earth, reports rang out one after another.

The ever-increasing rate of bullet surviving demonstrates that the balance of this war of attrition is steadily tilting in favor of human civilization.

But the atmosphere inside the command center remained extremely heavy.

Everyone stared intently at the holographic image in front of them.

On one hand, Zero is working hard to analyze the magnetic shield of the other civilization.

On the other hand, even though the Bosa fleet was powerless to intercept the increasing number of electromagnetic cannon projectiles, the combined shields rendered even antimatter projectiles far too weak.

Therefore, although human civilization had a slight advantage in the initial electromagnetic railgun duels, Bosa's fleet was still rapidly approaching the human fleet at a considerable pace.

At this moment, the Bosa fleet had already arrived at the edge of the Gliese 555 system!

"Enemy ship's magnetic field shield successfully analyzed!"

Just as Lü Yongchang and Zhao Zijie were pondering their next war plan, Zero brought them some good news!

"Great!" Lu Yongchang's eyes lit up and a look of joy flashed across his face.

Only 40% of the Bosa civilization's starships had composite shields; the remaining 60% used magnetic shields.

As a result, the defensive capabilities of most of the Bosa civilization's starships will be greatly reduced in the face of the human fleet!

"Has it been verified?"

Lu Yongchang quickly inquired.

"Preliminary verification has been completed, and the current accuracy rate is 100%."

The slightly stiff synthesized voice gave everyone in the command center a renewed sense of confidence!

"Activate the electromagnetic railgun intrusion procedure?"

"Not now!" Before Lü Yongchang could speak, Zhao Zijie hurriedly interjected, "We are too far away from the Bosa fleet. If we start the intrusion program now, the effect will probably not be very good, and it will easily arouse their vigilance."

"I suggest we wait until they get closer, and then initiate the intrusion at the most crucial moment!"

Lü Yongchang nodded: "Zero, I'll follow Zhao's orders."

An electronic synthesized voice then sounded.

"receive."

After a moment of contemplation, Zhao Zijie issued another order.

"Zero, mobilize all probes equipped with plasma bombs within the Gliese 555 system to deplete the enemy as much as possible."

"Also, speed up the production of detectors and drones."

……

Bosa Fleet.

"Commander, the fleet has successfully entered the target Heng system!"

The scratching sound, like fingernails scraping a blackboard, echoed in the command room of the Bosa flagship.

Commander Bosa stood with his back ramrod straight, staring at the screen in front of him with obvious impatience.

"What exactly is going on with this human civilization?!"

Why?

"Why are so many probes deployed near star systems?!"

As it spoke, it slammed its long, slender forelimbs onto the control panel in front of it: "Damn it, we've destroyed at least a million detectors since then!"

It took a deep breath, forcibly suppressing its inner rage, and said through gritted teeth, "And... can anyone tell me why they would install magnetic field shields and plasma bombs on these small detectors?!"

"How much more ammunition do we need to waste on these deadly detectors?!"

Obviously.

No one could tell him the answer.

Commander Bosa looked out the porthole at the scene, his forelimbs twitching slightly, a deep sense of powerlessness welling up from the depths of his heart.

It swore,

This is the most bizarre scene it has ever seen in all the interstellar wars it has commanded!

Outside the portholes of the Bosa fleet, detectors of all sizes were swarming in from all directions like locusts.

High-energy lasers were launched from the Bosa civilization's warships, rapidly destroying the probes that were trying to approach the fleet.

For some reason, the flight trajectories of these probes are extremely tricky and unpredictable!

This is why laser defense arrays are not particularly effective.

Just like...

It's as if an intelligent being is controlling each detector in real time!

The moment the thought crossed his mind, Commander Bosa shuddered.

Impossible, absolutely impossible!

How many intelligent beings must this civilization have to remotely control so many probes?

It shook its head vigorously, shaking off the absurd thoughts in its mind, and turned its gaze back to the porthole beside it.

Outside the porthole.

These detectors, relying on incredibly unpredictable maneuvers, broke through layers of high-energy lasers to launch suicide attacks on small warships on the outskirts of the fleet.

"commander!"

"Some warships' magnetic shields are about to overload!"

Commander Bosa's heart sank.

The worst-case scenario has indeed occurred.

Before even seeing the enemy fleet, the magnetic shields of the small warships couldn't withstand the attack!

"Switch fleet formation!"

It issued the order with extreme frustration: "Have all warships take turns defending against the attack, buying time for the magnetic field shield generator to cool down!"

……

Looking at the Bosa fleet constantly changing formation in the holographic projection, Zhao Zijie revealed a faint smile.

Finally, it's time to let other civilizations witness the saturation attack unique to human civilization!

He pressed the fleet-wide communication button and issued an order.

"Attention all units"

"Enemy ships have arrived at the designated area."

"Prepare to unleash [Ball Lightning]."

【Ball Lightning】, an unmanned plasma missile for which Tao Yuda proposed the design and completed the design.

Using the magnetic field generation unit inside the drone, it encases itself in high-temperature plasma and launches an attack on the enemy at extremely high speed.

With zero-control capabilities, these unmanned aerial vehicles (UAVs) are more flexible than detectors!

In terms of power, the offensive-focused [Ball Lightning] far surpasses those half-baked detectors!

The moment Zhao Zijie finished speaking, the gates of several spaceports suddenly opened!

An endless stream of drones poured out of these port gates!

The moment they leave the spaceport, the magnetic field generation unit inside automatically starts operating, and at the same time, the side hatches of the drones open rapidly.

A jet of scorching high-temperature plasma shot out from it!

Under the influence of the strong magnetic field, the pale blue plasma with golden arcs quickly enveloped the drone.

With this, the unmanned plasma missile was officially completed!

In just a few seconds, a pale blue "light curtain" suddenly appeared in the dark starry sky outside the porthole!

This light curtain is made up of countless drone-type plasma missiles!

"Covering up the sky and blotting out the sun..."

Zhao Zijie gazed at the scenery outside the porthole and murmured softly.
