Cataclysmic Era: I can unlock the tech tree

In deep space, 10,000 kilometers from Proxima Centauri b8, 120 Golden Crow battleships slowly raised the muzzles of their electromagnetic cannons.

With Zero's assistance, the electromagnetic cannon's muzzle was pointed directly at Proxima Centauri b.

"Fire!"

The moment the order was given, countless flames flickered once again in the depths of space!

Fire a barrage of artillery fire!

An electromagnetic railgun projectile can cross a distance of 80000 kilometers in just 13.3 seconds.

Inside the Earth, a countdown timer appeared before everyone's eyes.

【13】

【…】

【10】

[Alert! Alert!]

A flashing red light filled everyone's vision!

[Numerous enemy ship signals detected!]

The active detection device issued an alarm.

As if appearing out of thin air, countless signal sources appeared directly in front of the fleet!

Zhao Zijie's pupils suddenly contracted!

(At the reader's request, Zhao Zijie's pupils are now constricted.JPG)

He stared intently at the holographic image in front of him, his lips trembling slightly without his noticing!

What a big deal!

In the actively detected image, the vicinity of Proxima Centauri b is covered with countless, densely packed red dots!

Each red dot symbolizes a starship equipped with active detection equipment!

……

Near Proxima Centauri b.

Countless disc-shaped spaceships lay silently in deep space, waiting for invaders from the front to walk right into their trap.

"Liwai, they're here!" Augustus's voice came through the communication device.

"receive."

"This time, I'm going to teach these invaders a lesson they won't forget!"

Thinking of the 50 crashed spaceships, Levi's breath immediately spewed out bursts of hot air.

"Liwai, are you sure they only have 240 ships?" Augustus asked again.

Without any hesitation, Levi replied, "Of course! I saw it clearly!"

"Alright, they've sent half their forces. Active detection equipment shows 120 ships heading towards us," Augustus said calmly. "Maintain concealment. Wait until they're within range of all our weapons before attacking!"

He was silent for a moment, then spoke again: "Note that we are currently 12 kilometers away!"

Levi narrowed his six eyes slightly, staring intently at the deep space in front of him.

I can't see anything.

A bad feeling rose in his heart.

But thinking of the large army behind him, he shook his mind and banished the distracting thoughts.

In order to teach the invaders a painful lesson, the Proxima Centauri civilization dispatched all its combat-capable spaceships!

Abbreviation: All in.

"Wait, the enemy has slowed down!"

Augustus's voice, filled with surprise and uncertainty, rang out again: "What's going on? Have they discovered something?"

Levi's unease intensified once again.

"Impossible, right?"

"We remained silent the whole time, and from this distance, there was no way they could have detected us."

Augustus did not speak.

Clearly, he was observing the enemy fleet's movements from his position on the surface.

A few seconds later, a scream shattered the silence!

"Electromagnetic cannon! They've fired another electromagnetic cannon!!"

"Defense! Defend now!!!"

Augustus's desperate shouts rang out through the communication equipment!

……

Inside the human flagship, the Earth, located at the rear.

Enemy ship signals detected: 381 ships

[Update: Enemy ship signals detected: 870 ships]

【…】

The numbers in the holographic projection kept jumping.

Ultimately, it stopped at a chilling number.

[Enemy ship signal: 5181 ships]

The moment Zhao Zijie saw this number, his eyes widened in shock!

It's over, Barbie Q.

5181 VS 120

Anyone with a normal mind knows what the outcome would be!

"Retreat! Retreat immediately!"

Second Fleet Commander Brad has issued the order to retreat.

But the Second Fleet, thousands of miles away, made no move.

"Calm down, Brad!"

Lü Yongchang directly intercepted the order issued by Brad.

"Zero, fire the giant flare!"

In this urgent situation, Lü Yongchang directly handed over command of the fleet to Zero.

……

With the launch of the electromagnetic cannon, the Proxima Centauri fleet broke its previous state of silence.

Faced with the overwhelming electromagnetic cannon projectiles, the planetary defense network and the Proxima Centauri fleet worked together to intercept them all with the help of high-energy laser cannons and electromagnetic cannons!

In an instant, countless explosions and flashes of light appeared between the two fleets!

Just as Levi was preparing to launch an attack, 120 dim points of light appeared directly in front of them.

What is that?

Livay was stunned for a moment.

Before he could react, an incredibly intense light was released from those 120 dim points of light!

……

In the center of the battlefield, it looked as if a small star had appeared!

Illuminated by the giant flares, the Proxima Centauri fleet revealed its true form!

The optical telescope swept across at an extremely fast speed!

Zero! Analyze the enemy fleet composition!

Lü Yongchang quickly issued his orders.

In less than a second, the statistics appeared before everyone's eyes.

Enemy ships with a diameter of over 1000 meters: 1

Enemy ships with diameters of 500-1000 meters: 2

Enemy ships with diameters of 100-500 meters: 1070

Enemy ships with diameters of 50-100 meters: 2008

Enemy ships with a diameter of less than 50 meters: 2100

How can there be spaceships with a diameter of less than 50 meters?!

What is this?

A combination of the elderly, weak, sick, and disabled?

"Gentlemen, you have all seen the enemy ship configuration."

"If nothing unexpected happens, these should be all the starships of the Proxima Centauri civilization."

"Retreat? That's not my style!"

"I hereby declare the fleet to set sail! Prepare for the general offensive!"

The order was given, and the Earth and the other starships changed course and headed towards Proxima Centauri b!

At the same time, a message appeared before everyone in the First and Second Fleets.

[Attention all units, free attack! I repeat, free attack!]

Hold on! Reinforcements are on their way!

……

Illumination flares have a two-way effect.

When humanity observed the true form of the Proxima Centauri fleet, Proxima Centauri also observed the appearance of the human fleet.

only……

The sight of 120 neatly arranged starships, each 1500 meters long, clearly had a significant psychological impact on them.

An eerie silence fell over the battlefield.

But soon, this long-awaited tranquility was shattered by Livay.

With the help of the onboard computer, he fired a series of electromagnetic cannon shots at a Golden Crow battleship within his sights!

Livay's action was like a signal.

Within seconds, 5181 Proxima Centauri ships and the planetary defense network simultaneously sounded the charge for attack!

Countless electromagnetic cannon projectiles charged toward the 120 Golden Crow battleships ahead!
