Cataclysmic Era: I can unlock the tech tree

The information, after zero processing, quickly appeared on the holographic projection.

"Remember our name, the Bosa civilization!"

"We are the Lord's most faithful believers!"

"Human civilization, you have incurred the Lord's displeasure!"

"You will pay a heavy price for this!"

"For a mere fourth-level civilization like yours, surrendering is the only wise choice!"

"Humans, disarm yourselves and relinquish control of the central computer, and perhaps the Lord will spare your lives!"

Inside the command center, all was quiet except for a few sharp noises, like scratching at the darkness, coming from the loudspeakers.

Lu Yongchang raised his hand and gently rubbed his eyes, seemingly unable to believe the information he had seen.

"host?"

"Zero, are you sure there are no errors in the translation?"

Lü Yongchang asked Ling in surprise.

The next second, a brand new holographic projection appeared in front of everyone.

The contents include detailed dictionary information, even specific pronunciation information.

"Professor, for better understanding, this part of the title uses a free translation." Zero's unique electronic voice echoed in the command center.

"The title literally translates to 'the deity who gave it life and technology.'"

Lu Yongchang's expression shifted slightly.

He raised his hand and gently stroked his chin, gazing thoughtfully at the "giant stick insect" waving its forelimbs in the holographic projection, and murmured softly, "There's quite a lot of information contained in that name!"

"The deity who bestowed life and technology upon them..."

"interesting!"

Lu Yongchang raised his head, looked directly at the large stick insects with "straight" figures in the holographic projection, and said in a very calm tone.

"Is the 'master' you speak of the Cleaner Civilization?"

As he spoke, a holographic image appeared beside Lü Yongchang.

The image projected was none other than the spherical detector whose outer shell of the strong interaction material had been shattered by the torrent of antimatter!

The crackling sound from the communication speaker suddenly increased significantly.

Moreover, the large stick insects in the video call were now absolutely furious!

Don't ask how you could tell the emotions of a large stick insect.

Just from their forelimbs waving like windmills in front of their thoraxes, Lü Yongchang could tell how much his words had stimulated these large stick insects!

"Damn it!"

"You lowly ants!"

"How dare you address the Lord by His name!"

"You are guilty!"

"You have no chance to surrender!"

The video call was cut off the next second.

Lü Yongchang shrugged and turned to look at Zhao Zijie beside him: "What are you standing there for?"

"Fire!"

The war officially began with a metallic storm of antimatter electromagnetic cannons.

……

As a subordinate civilization of the Cleaners civilization, the Bosa civilization was naturally well aware of the common tactics of interstellar warfare.

Therefore, after failing to persuade them to surrender, the Bosa civilization also chose to use electromagnetic cannons as the first weapon in the war.

Although electromagnetic railguns have many limitations, as the most basic kinetic energy weapon, while balancing kill range and lethality, they have one major advantage—cheapness.

At least for a level four, or even a level five civilization, electromagnetic cannon projectiles are the cheapest weapon.

A metal storm composed of millions, tens of millions, or even hundreds of millions of shells can not only be used to test the strength of enemy ships, but also to take the opportunity to damage some of the weakly defended enemy ships.

"Commander, an attack by human civilization has been detected!" a large stick insect reported in a shrill voice. "Weapon type: electromagnetic cannon!"

Looking at the data transmitted back by the detection device, Commander Bosa's eyes revealed a contemptuous smile.

A Level 4 civilization is just a Level 4 civilization; they can't even bear to use basic weapons like electromagnetic railguns.

Look at the ratio of ammunition fired by both sides; the number of shells fired by human civilization was only half of theirs!

Such a huge difference in numbers immediately made Commander Bosa relax his vigilance considerably.

He even ordered the orientation of the optical telescopes in the probes to be adjusted, in preparation for the flashes of explosions from the human fleet!

After a relatively short waiting period, the electromagnetic cannon projectiles fired by both sides finally met in the vast expanse of space.

Commander Bosa squinted his already small eyes and looked at the scene in front of him.

He had seen this kind of scene many times before.

It's nothing more than a small number of projectiles colliding with each other, sparking some fire.

It's nothing serious.

Suddenly, he widened his eyes slightly.

"The flash of an explosion?"

"Why was there a flash of light from the explosion?!"

Looking at the images transmitted back by the probe, Commander Bosa suddenly had a bad feeling.

After a short wait.

"High-energy gamma rays!"

A Bosa man, his face showing a hint of horror, shouted, "Commander, the detectors have detected a large dose of high-energy gamma rays!"

"It's antimatter! Their projectiles contain a large amount of antimatter!"

Commander Bosa's expression darkened, and his initial desire to watch the show vanished instantly.

"Antimatter?" He waved his two pairs of slender forelimbs rapidly in front of his chest, seemingly venting his inner rage. "Are they insane?!"

"Adding antimatter to electromagnetic railgun shells would increase the cost of a single shell by at least a hundred times!"

The detector shows that the number of electromagnetic projectiles fired by our side is rapidly dissipating.

"Quickly!" Commander Bossa abruptly stood up from his seat, roaring through gritted teeth, "Continue firing the electromagnetic cannon!"

"Stop them all!"

……

In the dark space of space.

With Zhao Zijie's command, the electromagnetic railgun projectiles that were fired first and positioned at the front all initiated their self-destruct sequence.

A large amount of antimatter was released.

The annihilation reaction generates immense energy the moment it contacts the inner wall of the shell!

This energy instantly tore the thick outer shell of the shell apart completely!

The specially designed cartridge case ensures that the shrapnel generated by the explosion scatters forward.

The electromagnetic cannon projectiles fired by the Bosa civilization were instantly disrupted from their original trajectories by the impact of these extremely high-speed shrapnel fragments.

Meanwhile, the antimatter projectiles located at the rear took this opportunity to rush forward!

They bypassed the intense gamma rays and the aftershocks of the explosion, heading straight for Bosa's fleet!

……

"Another electromagnetic cannon shot detected!"

Urgent reports rang out in the command center.

Zhao Zijie quickly reviewed the various data transmitted back by the detector, and after a moment's thought, he issued the order in a deep voice.

"Continue firing the electromagnetic railgun."

"Execute the same strategy."

"Since they want to wage a war of attrition, we'll play along to the bitter end!"

As he spoke, Zhao Zijie turned his head to look at the porthole next to him.

Outside the porthole, various space factories, under Zero's control, were working at full capacity to produce all kinds of weapons and ammunition.

Meanwhile, the [Taotie] supply depot and the Dawn Star space elevator are continuously transporting various supplies.

In the far distance, near the main star Gliese 555, the Dyson Cloud is working at full speed to produce antimatter...

This is the advantage of playing a defensive game.

With a star system at our backs, as long as the production speed keeps up, ammunition and supplies are no problem at all!
