Cataclysmic Era: I can unlock the tech tree

The battering ram is not used to attack those scattered magnetic field shields.

From its inception, it was designed as a strategic weapon capable of delivering a decisive blow.

Therefore, facing the impending attack, Lü Yongchang did not hesitate and immediately gave the order.

"【Golden Crow】Activate Plasma Shield."

As soon as the words were spoken, the light from the Hall thrusters at the stern of the [Golden Crow] battleship dimmed slightly.

A large amount of energy was rapidly transferred to the magnetic field generating unit.

At the same time, the rear hatch opened rapidly, and high-temperature plasma, which was entirely blue, gushed out from it. Under the influence of the magnetic field, this plasma enveloped the entire [Golden Crow] warship like an eggshell.

This is the strongest defensive configuration of the [Golden Crow] battleship.

Before the appearance of the battering ram, even the human fleet itself needed to expend a lot of effort to break through this "turtle shell".

"Professor, the battering ram is ready and can be used to launch an attack at any time."

Zero's notification sounded in the office.

"Initiate the attack!"

"It was a deep voice," Lü Yongchang said.

……

As Lü Yongchang gave his order, a dazzling light shone in the dark and deep universe.

Inside the siege hammer, a large number of nuclear fusion reactors, enough to power three Golden Crow battleships, were operating at full power at this moment!

All the energy generated surged towards the front muzzle of the battering ram!

A faint blue light began to appear at the muzzle of the cannon.

next moment!

Before anyone could react, endless plasma gushed out from the cannon's muzzle!

Under the strong magnetic field channel created by the drone, these plasmas are constantly accelerating! Accelerating! Accelerating!!

The 100-kilometer-long acceleration pipe allowed these high-temperature plasmas to reach an unbelievable speed!

Like a bolt of dark blue lightning, this column of dark blue plasma, with a diameter of one hundred meters, spewed out from the invisible cannon barrel constructed by the magnetic field.

At the same time, the light from the Hall thruster at the rear of the siege ram gradually went out.

The hull near the gun muzzle even showed some deformation!

Some of the remaining dark blue plasma, carrying golden electric sparks, slowly seeped from the surface of the ship, damaging the already fragile hull.

It was scrapped.

Under such overload operation, it can only fire this one and only shot in its entire life!

But nobody cares about that.

All eyes were on that one "swan song" it unleashed!

In an instant, a dark blue "lightning" struck the pale blue plasma shield near the [Golden Crow] battleship!

Initially, due to the impact of a large amount of external plasma, the color of the plasma shield suddenly darkened considerably.

It changed from its original light blue to a deep blue due to overload.

Of course, this only happened in a fleeting moment.

In the next instant, the overloaded magnetic field shield generation units collectively went on strike—they were overloaded.

The plasma that initially orbited the Golden Crow was now freed from the constraints of the magnetic field and began to scatter outwards tangentially.

Against the backdrop of the deep, dark universe, these plasmas formed an incredibly brilliant picture.

At this moment, the [Golden Crow] battleship was like a hedgehog with its feathers bristling.

However, unlike normal hedgehogs, the sharp spines on the surface of this large "hedgehog" are all extremely powerful plasma.

This is far from over.

The powerful plasma column from the [Battle Ram] is still more than half intact!

After the magnetic field shield generation unit went out of service, the remaining plasma columns rushed straight toward the [Golden Crow] battleship!

Without a magnetic field shield, the Golden Crow could only pin its hopes on its thick armor.

Obviously.

For a plasma column with a diameter of 100 meters, this thick armor is no different from paper.

The dark blue plasma column plunged directly into the bow of the [Golden Crow] battleship without any hesitation!

After a brief wait, a small amount of plasma gushed out from the tail of the Golden Crow.

Penetrating wound!

A powerful burst of fire appeared in the dim universe.

Spike! !

Although the battering ram only launched one attack, the power of that attack deeply shocked the hearts of everyone in the laboratory.

……

"hiss……"

Tao Yuda, standing next to Lü Yongchang, took a deep breath.

"How was it? Pretty powerful, huh?" Lu Yongchang turned around and said with a smile.

"Yes, it's pretty good," Tao Yuda replied with a somewhat strained nod.

"Unfortunately, it can only launch one attack." Saying this, Tao Yuda glanced regretfully at the siege ram, now a large chunk of scrap metal. "If we had more powerful materials, perhaps we could..."

"There's no need."

"Lu Yongchang said softly."

"What?" Tao Yuda was stunned for a moment, not quite understanding.

"This will not change even with stronger and more durable materials."

"Why, why?" Tao Yuda found it hard to accept this explanation.

At first, he thought it was all for the sake of pursuing higher attack power.

But Lü Yongchang's statement completely refuted his speculation.

"Why?" Lü Yongchang chuckled. "Do you think, in a real interstellar war, the enemy would allow this thing to fire a second shot?"

"Even with the protection of the drone swarm, the charging time of several seconds is enough for the [Golden Crow] battleship to tear it to shreds."

Tao Yuda's face was filled with astonishment.

That seems...to make sense?

He gazed thoughtfully at the wreckage in the holographic projection, seemingly drawing some inspiration from the weapon's design.

"professor."

Do you know what ball lightning is?

Tao Yuda's eyes gleamed with excitement as he murmured to himself.

"Huh?" Lü Yongchang was taken aback. "Ball lightning? That strange physical phenomenon from Earth's time?"

A distant memory surfaced in his mind.

It was a thunderstorm.

An orange-red "fireball" travels against the wind in the air.

It traced a strange yet graceful curve and slipped into the research institute's room through a crack in the window.

"boom!"

After a loud bang.

The "fireball" exploded.

That accident caused considerable losses to the research institute.

"Of course I know," Lü Yongchang said with a touch of nostalgia. "I remember there were quite a few people studying this amazing natural phenomenon back then."

"Now it seems that it does resemble our plasma weapons somewhat."

"Yes, yes, yes!" Tao Yuda nodded repeatedly, "Like a ball of plasma enveloped in a strong magnetic field!"

"Since we can treat the battering ram as a disposable weapon, why can't we treat the drones it carries as disposable weapons as well?"

"No, it's not just the battering ram; it can be used on every warship."

Lü Yongchang's expression shifted slightly.

He seemed to understand the meaning behind Tao Yuda's words.

"You mean, designing drones as disposable... plasma projectiles?"

"No, it's not a shell." Tao Yuda's expression grew increasingly agitated. "To be precise, it should be a missile."

"Under zero-based control, these plasma-encased drones can achieve full-range guidance and carry out precision strikes against targets!"
