Cataclysmic Era: I can unlock the tech tree

Observatory.

Augustus stared at the monitor in front of him, his three pairs of eyes filled with disbelief.

The display shows real-time images from the Proxima Centauri optical probe.

The flagship and supply ships, which had been clustered together, had now dispersed.

Behind that enormous flagship, a 5000-meter-long building rests silently in the quiet of space.

Judging from the supply ships docked next to the building, Lyle was right.

That damned solar system civilization actually built a huge factory in space!

And all of this was accomplished in just one month!

Augustus took a few steps back, muttering to himself, "This, this is impossible!"

"How did they do that...?"

As he watched the supply ships leave the space factory and head straight for the warships on the other side, a sense of crisis welled up in his heart!

"Quick! Prepare for defense..."

Before he could finish speaking, another piercing alarm sounded!

"Lord Augustus! The invaders' warships are heading our way!"

The observer's shrill shouts echoed throughout the observation room.

……

[30000 km].

The sterns of 120 Golden Crow battleships shone with a deep blue light!

In the dark universe, it looked as if 120 small suns had risen!

The immense thrust propelled the Golden Crow battleship toward Proxima Centauri B!

At the same time, a steel torrent composed of countless electromagnetic cannon projectiles reappeared.

Unlike the previous ones, this electromagnetic railgun projectile does not contain a miniature nuclear bomb.

Even so, these projectiles possess extremely high destructive power due to their extremely high speed!

Without the interference of those small starships from Proxima Centauri, explosions and flashes continued to appear within the planetary defense network.

The Proxima Centauri civilization's planetary defense network is crumbling at a visible rate!

……

Proxima Centauri b.

The underground city of the Central Academy of Sciences.

Augustus's breathing holes opened slightly, and his rapid breathing revealed his inner panic.

"Damn it! Damn it!"

He paced back and forth in the observation room, occasionally glancing at the battle situation on the monitor beside him.

Each time he turned his head, his mood worsened.

"Lord Augustus..."

The observer's voice was filled with terror: "The planetary defense network... is gone."

Augustus abruptly stopped and turned to look at the screen again.

The mesh-like structure that originally enveloped Proxima Centauri b is gone, replaced by a huge gap!

The gap is shrinking at an extremely slow rate.

That was the railguns in the other areas urgently changing their tracks.

However, faced with the relentless onslaught of human fleets, such measures were undoubtedly a case of locking the barn door after the horse had bolted!

A glint of madness flashed in Augustus's eyes: "Wait a little longer!"

"Wait until they're within 20000 kilometers before using our land-based laser weapons!"

"This time, I'm going to destroy all their warships within 20000 kilometers!"

……

[25000 km]

The Golden Crow battleship had only advanced 5000 kilometers when a huge hole was torn in the originally impenetrable planetary defense network!

[Attention all personnel, prepare to fire smoke grenades!]

The order from Lü Yongchang was presented to all the captains.

The Golden Crow's speed of movement gradually slowed down.

At least, they will never cross that life-or-death threshold of 20000 kilometers before the smoke grenades take effect.

After they stopped advancing, a crack simultaneously appeared on the top of each of these Golden Crow battleships.

Temporarily installed cannon barrels slowly emerged from them.

Unlike the barrel of an electromagnetic railgun.

It's not even a pipe.

Instead, there are two guide rails that are over ten meters long.

Under electromagnetic influence, the massive interstellar smoke bomb will accelerate along the guide rail to a speed of 1000 km/s.

As the launch order was given, the Plus version of the projectile slowly accelerated along the guide rail and rushed straight towards the front of the fleet!

First volley.

120 enormous smoke bombs wobbled toward Proxima Centauri b.

A few seconds later, the smoke grenades entered the range of the Proxima Centauri ground-based laser weapon—20000 kilometers.

The Proxima Centauri civilization, prioritizing stability, did not allow these smokescreens to continue.

When they discovered that the planetary defense network was no longer effective, they directly deployed ground-based laser weapons!

The beam of light flickered several times, and the flames of the explosion appeared in interstellar space.

Each smoke grenade explosion releases countless carefully crafted asteroid dust particles into the surrounding area!

In an instant, a yellowish smoke barrier appeared between the Golden Crow battleship and Proxima Centauri B!

To make it easier to identify, Lü Yongchang specially added a small amount of dye to the asteroid dust.

This is why the dust appears yellowish-brown.

[All Golden Crow battleships, continue forward!]

The moment the smoke barrier appeared, Lü Yongchang gave the order to advance once again.

The second salvo was launched simultaneously!

Perhaps what just happened was somewhat unexpected for the Proxima Centauri, because this time, these projectiles were not blocked.

But this does not affect the final outcome.

When the smoke bombs arrived at their designated location, the miniature nuclear bombs inside were remotely detonated!

In a mere instant, the high temperature and pressure generated by the nuclear explosion triggered a deuterium-tritium fusion in the outer layer!

A second layer of yellowish-brown dust barrier appeared!

The 120 [Golden Crow] battleship calmly entered within 20000 kilometers.

The land-based laser cannon flashed again, piercing through the dust and shining directly on the lead [Golden Crow] battleship!

The original scenario of it exploding at the slightest touch did not occur.

laugh……

A slight burning sensation appeared at the laser beam's irradiation point.

But such power is like a tickle to the thick armor of the Golden Crow battleship!

A third volley!

Fourth round of volleys!

Each salvo creates a yellowish smoke barrier directly in front of the fleet.

As the number of barriers increases, the power of the high-energy laser beams weakens.

The Golden Crow battleships slowly advanced their battle lines along these barriers, occasionally firing a few electromagnetic cannons to deal with the planetary defense facilities that had changed their orbits.

The moment they realized that the land-based laser cannons were ineffective, the Proxima Centauri civilization, which had been sitting on its laurels, began to panic.

For a moment, high-energy laser beams flickered wildly in interstellar space.

However, faced with an unprecedented onslaught of smog, the offensive of these high-energy laser beams appeared incredibly weak.

As the number of smoke grenades launched increased, a 20000-kilometer-long, layered, yellowish-brown smoke trail gradually appeared outside Proxima Centauri b.

As the Golden Crow battleship approached Proxima Centauri b, smoke grenades rained down into the atmosphere of Proxima Centauri b like dumplings being dropped into a pot!
