Cataclysmic Era: I can unlock the tech tree

Accompanied by a tremor imperceptible to outsiders, a large amount of dark blue high-energy plasma gushed out from the internal pipes of the [Battle Ram]!

Simultaneously,

The drones that construct the gun barrel also change the magnetic field operation mode.

The dark blue high-energy plasma began to slowly accelerate within the void cannon barrel, while golden electric light flickered around this powerful plasma column and continued to extend towards the end of the cannon barrel, a hundred kilometers away!

Such scenes occurred in every corner of the battlefield!

Almost simultaneously, hundreds of giant, dark blue plasma pillars, their lengths constantly increasing, appeared in the battlefield that was originally filled with the sounds of gunfire!

The medium-sized Bosa warship that was the target had obviously also detected this threatening attack.

Its first reaction is to maneuver and evade.

But at some point, two Golden Crow battleships approached from the side, using a large number of shipborne drones to briefly block all its escape routes.

To carry out an evasion maneuver, it is necessary to deal with these surrounding "obstacles".

This will consume a lot of energy and time.

Left with no other option, the Bosa warship had to attack the ram in an attempt to eliminate this outlandish weapon at its source.

Seeing the impending attack warning flashing in the holographic projection, Andrew, who was crouching next to the battering ram, did not hesitate at all and immediately gave the order!

A large number of shipborne drones, carrying eerie blue plasma shields, swiftly flew to the vicinity of the [Battle Ram], using their own bodies to block wave after wave of attacks for it!

Finally, under the continuous acceleration of the magnetic field, the giant plasma column quickly reached the end of the cannon barrel!

boom!

A ghostly blue plasma gushed out from the void cannon barrel constructed by the drone!

Using its momentum, it rushed straight toward the distant target!

Faced with the impending attack, this medium-sized Bosa warship had lost all chance to resist and could only raise its composite shields, pinning its hopes on the extremely strong shields!

The antimatter engine at its tail dimmed slightly, but the intensity of the emitted gamma rays did not decrease in the slightest.

Clearly, in order to withstand the attack of the [Battle Ram], it diverted most of its energy to the shield system.

boom!!

Just as the medium-sized Bosa warship was ready, the dark blue plasma slammed straight into it!

Splash!

At that moment, a large amount of high-temperature plasma was sprayed outwards!

A magnificent flower, constructed from high-temperature plasma, blooms in the dark universe!

These high-temperature plasmas slowly outlined the shape of the Bosa warship's shield—an ellipsoid resembling an egg.

The plasma columns continuously bombarded the composite shield, increasing the load on the shield system.

at last.

A blinding flash of light followed, and a scene resembling a soap bubble bursting appeared before everyone's eyes!

The first layer of the composite shield, the magnetic field shield, was completely overloaded at this moment!

But the attack of the [Battering Ram] was not over yet; the nearly 1,000-kilometer-long, dark blue plasma column had become the most dazzling existence in this universe!

Without the assistance of the magnetic field shield, the gravity shield was naturally powerless and slowly dissipated after struggling to hold on for a few seconds.

next moment.

The dark blue plasma column shot straight in and slammed directly into the outer armor of the Bosa warship!

The three Golden Crow battleships around them naturally wouldn't let such a good opportunity pass them by.

With the orders of the three captains, endless artillery fire instantly engulfed the Bosa medium-sized warship!

The plasma column slowly dissipated.

The battering ram has a dark red surface, and thick smoke is billowing from some key parts.

For this attack, it consumed all its stored plasma and even sacrificed its "life"—it was rendered unusable.

Bang!

The flames from the explosion illuminated its wrecked body from afar.

That was the fire from the explosion of the Bosa medium-sized warship.

Without the protection of an outer armor, and with Zero's assistance, a high-energy laser precisely pierced its antimatter engine!

The antimatter leaked out and blasted it into pieces!

This was also the first core vessel of the Bosa fleet to be destroyed in this war!

Bang!Bang!Bang!

The flash of that explosion seemed to have flipped a switch, and as the dark blue plasma column slowly dissipated, bursts of explosions flickered across the battlefield.

Some of these explosions came from the Bosa fleet, while others came from the [Golden Crow] warship!

The scales of victory are once again slowly tipping in favor of the human fleet!

……

The good times didn't last long.

Although the Bosa fleet lost a large portion of its core strength in the attack just now.

However, correspondingly, the human fleet's battering rams were also being heavily depleted in a short period of time.

Although the factories located near Dawn Star are operating at full capacity, these battering rams are not easy to manufacture. Moreover, each attack requires a large amount of energy and high-energy plasma.

Although the advance of Bosa's fleet was briefly halted by the attack of the battering rams, it was not long before Bosa's fleet launched a counterattack as the number of battering rams decreased.

Faced with the increasingly fierce offensive of the Bosa fleet, the human fleet could only retreat continuously.

……

Earth

As the red area on the star map continued to expand, the expressions on everyone's faces turned rather grim.

"Zero, where is the antimatter transport ship?"

As Bosa's fleet drew ever closer, the third defensive zone was on the verge of falling, and Lü Yongchang could only place his hopes on the most powerful war fortress of human civilization.

However, this most powerful war fortress is currently mired in a quagmire of energy shortages.

"Professor, the antimatter transport ship has arrived on Gliese Planet 4."

Several bright spots lit up on the holographic star map directly in front of them.

Zhao Zijie pursed his lips tightly, a hint of anxiety flashing in his eyes: "The fourth planet... is almost there, but the enemy is about to break through the third defensive zone!"

"We must hold this position!" Lü Yongchang said in a deep voice. "At the very least, the third defensive zone cannot be lost until the Guangwei-1 planetary fortress has replenished its antimatter reserves!"

Zhao Zijie remained silent for a moment, then nodded with an extremely solemn expression: "Okay!"

"Attention all units"

"Hold the third line of defense at all costs."

"...Thirty minutes!" He paused for a moment, then added, "Hold out for thirty minutes, wait for the Titan planet fortress to replenish its antimatter reserves, then retreat!"

As he spoke, Zhao Zijie felt as if a huge hole had been ripped open in his heart.

As the military commander of the human fleet, he naturally knew what kind of consequences his order would cause—massive casualties!

"Professor, the Dimensional Strike Ship..."

After hesitating for a moment, Zhao Zijie finally decided to ask.

Upon hearing Zhao Zijie's question, Lü Yongchang fell silent.

After a moment, he sighed heavily and shook his head with difficulty.

"It's not the right time yet."

"We don't have many two-dimensional fragments left, so we have to use them sparingly."

"Besides the Bosa fleet, human civilization may face even more dangers in the future!"

"Two-dimensional fragments... it's best to avoid using them if possible."

Zhao Zijie naturally understood this principle as well.

He swallowed hard and turned his anxious gaze to the slowly moving point of light on the star map.

Just how much energy does the antimatter inside a Golden Crow battleship possess?

I imagine the Bosa fleet will find out soon.
