Cataclysmic Era: I can unlock the tech tree

Before the men arrived, the cannons came first!

The precise metal storm caught the Proxima Centauri civilization off guard.

The Proxima Centauri flagship, which had been swaggering around the Golden Crow fleet with its superior range, no longer had the energy to launch another attack.

Countless lasers and electromagnetic guns were fired from its surface to intercept incoming electromagnetic projectiles.

However, due to "software issues," many projectiles still bypassed its defenses and struck its surface directly.

Explosions and flashes of light appeared one after another on its outer armor, demonstrating the full power of a close-range nuclear explosion!

In just one encounter, the lone Proxima Centauri flagship was plunged into crisis!

At this moment, Bai Yixuan also realized what was happening.

Following the fine tradition of striking while the iron is hot, Bai Yixuan immediately gave the order.

Change direction and launch a counterattack!

The A21 battleship, named 【Golden Crow】, traced a smooth arc in space and headed straight for the retreating Proxima Centauri flagship.

Of course, the Proxima Centauri fleet wouldn't just watch its flagship die in vain.

Almost simultaneously, countless shells and laser beams were fired toward the human fleet!

Whether it's accurate or not, I don't know, but it certainly has a huge impact!

In an instant, the war entered a white-hot phase!

On the battlefield, countless electromagnetic railgun projectiles flew in all directions, and high-energy laser beams swept towards enemy ships and electromagnetic railgun projectiles like rain.

In the midst of this chaotic battlefield, a [Golden Crow] battleship braved endless electromagnetic cannon shells and high-energy laser beams, sailing against the current and heading straight towards the Proxima Centauri flagship!

The terror of zero is fully revealed at this moment.

The 1500-meter-long battleship, like a swimming fish, constantly navigated through a hail of bullets.

With the help of electromagnetic cannons and high-energy laser beams, it continuously dealt with oncoming attacks, closing the distance between itself and the enemy flagship!

Bai Yixuan stared intently at the holographic projection in front of him, which was flashing red light continuously.

[60000 kilometers!]

[High-energy ion beam weapon, charging initiation...]

[55000 kilometers!]

[Charging complete!]

[50000 kilometers!]

"White Team, the range is sufficient!"

Hong Fan's information flashed on the holographic projection!

At that moment, the scene of his own starships exploding one after another flashed before his eyes!

"Fire!"

Bai Yixuan issued his command with a ferocious expression.

In the distance, on the exhausted Proxima Centauri flagship, a sudden burst of fire appeared!

boom!

A violent explosion erupted from inside the enemy flagship's armor, instantly tearing a huge gap in the tight armor!

From the gap, countless broken parts were sprayed out with the airflow.

But the enemy ships did not slow down their escape at all; on the contrary, they accelerated their escape.

"Damn it, isn't the fusion reactor here...?"

Bai Yixuan looked at the image in the holographic projection, a hint of disappointment showing between his brows.

Unfortunately, they were a bit unlucky.

How much longer until the second ion beam is ready?

Hong Fan's response came immediately: "Ten seconds!"

[50000 km]

The numbers displayed in the holographic projection kept changing.

The difference in starship maneuverability was immediately apparent, and the distance between the two widened again. In the blink of an eye, the enemy flagship escaped the firing range.

Bai Yixuan's expression changed slightly.

That's too late!

"White Team! The second ion beam is fully charged!" Hong Fan's message flashed before his eyes.

Watching the enemy flagship's trajectory gradually veer off course, and recalling the memories he shared with his old teammate Wu Ran, Bai Yixuan felt a surge of anger rising within him.

"Hong Fan, let's chase after them..."

Before the message was even sent, a highlighted notification popped up in front of him.

[Jinwu A21, your position is too far forward, move back immediately!]

It was an order from Zhao Zijie, commander of the First Fleet.

Bai Yixuan looked somewhat dazed as he glanced at the star map beside him.

As Zhao Zijie said, during the pursuit just now, he had unknowingly strayed from the main force and become a lone force deep in enemy territory.

He took a deep breath of the deep-sea liquid, forcibly suppressing the complex emotions in his heart.

"Golden Crow A21 received. Begin retreat."

……

The withdrawal of A21 from the Golden Crow battlefield was insignificant in the grand scheme of things.

Lu Yongchang, aboard the flagship Earth, watched the enemy flagship on the projection, which was teetering on the brink of collapse and heading towards Proxima Centauri b, and a ruthless glint appeared in his eyes.

"You killed so many of us, and you still want to go back alive?"

"Zero, prepare to deploy the nuclear torpedo."

As soon as he finished speaking, a prompt appeared in the holographic projection.

[Nuclear torpedo is ready. Launch?]

Nuclear torpedoes: a trump card for human civilization.

Academician Qian Zhengyang successfully realized Lü Yongchang's vision.

A simplified version of a plasma weapon.

By using a high-yield directed nuclear explosion, a beam of ultra-high temperature plasma can be generated over an extremely short distance!

The main body of the nuclear torpedo is an interstellar missile, equipped with a Hall thruster unit similar to that of the Golden Crow battleship.

The overall size is close to twenty meters.

Even so, its size and mass are still extremely small compared to a starship.

With its powerful thrust, it can accelerate to 5000 km/s in just a few seconds.

Such acceleration performance is terrifying!

Although the fleet's maximum cruising speed can reach 10% of the speed of light, or 3 kilometers per second, that speed can only be achieved through long-term acceleration.

In war, starships often have their speed significantly reduced in order to maintain their mobility.

Based on the data collected during this period, even the Proxima Centauri fleet, which is known for its mobility, has a maximum cruising speed of only 2000 km/s in wartime!

This is precisely why nuclear torpedoes have room to be used!

Thanks to Qian Lao's intensive use of materials, the performance of this interstellar missile far exceeded Lü Yongchang's initial design.

Of course, the consequence of this frantic use of materials is a shortage of production.

Even at zero, only a few dozen were produced before the mission began.

Looking at the flashing notification in front of him, Lü Yongchang cleared his mind of distractions and solemnly issued his command.

"emission!"

A faint blue flame instantly illuminated the side of the Earth!
