Cataclysmic Era: I can unlock the tech tree

Back in his office, Lü Yongchang picked up a pen from his desk, pulled out a brand new A4 sheet of paper, and began to write and draw.

It didn't take long for a standard sketch to appear on the paper.

The camera next to it rotated its angle, carefully "observing" the pattern on the paper.

"Professor, you want to use a superconducting magnetic energy storage device?"

The moment Lü Yongchang put down his pen, Zero's question rang out.

Upon hearing Zero's question, a look of surprise appeared in Lü Yongchang's eyes.

This should be the first time Zero has actively speculated about the content he drew on the blueprints.

"Zero, do you recognize this?"

As soon as he finished speaking, a self-deprecating smile appeared on Lü Yongchang's face.

That makes sense; how could Zero not recognize this thing?

"Yes, Professor, its information is in the database." Zero, unaware of Lü Yongchang's thoughts, answered truthfully.

The principle of superconducting magnetic energy storage devices is very simple: they are coils made of superconducting materials.

The power grid inputs current into it, creating a magnetic field in the coil, thereby storing energy.

Furthermore, due to the characteristics of superconducting coils, the current will always exist in the closed coil.

The current is released only when needed.

This cycle constitutes a simple energy storage device.

Compared to conventional energy storage devices, superconducting magnetic energy storage devices have many advantages.

Firstly, it can store energy for a long time without loss.

Secondly, it is what Lü Yongchang needs: fast response speed and extremely strong charging and discharging performance!

In summary, based on the above two points, it can be said that this is the perfect energy storage device for an electromagnetic gun!

The reason why previous electromagnetic railguns did not use this device is quite simple.

Without room-temperature superconducting materials, superconducting magnetic energy storage devices are expensive and consume a great deal of resources, making them a poor investment.

Lu Yongchang pulled himself out of his thoughts, relaxed slightly, leaned back in his office chair, and said softly.

"Since you have the data in your database, please help me simulate what scale of superconducting magnetic energy storage equipment would be needed to meet the requirements of an electromagnetic railgun."

"Understood, Professor!"

As Zero finished speaking, the holographic image flashed, illuminating the somewhat dim room.

……

half a month later.

Yevgeny, with dark circles under his eyes, knocked on the door of Lü Yongchang's office.

"professor……"

Yevgeny shouted in an extremely weak voice.

"Click".

A sound of a lock turning was heard, and the door opened automatically.

"Holy crap!" Upon seeing Yevgeny outside the door, Lü Yongchang let out a heart-stirring exclamation. "Professor Yevgeny, what happened to you?"

Upon hearing Lü Yongchang's question, Yevgeny weakly tugged at the corners of his mouth, revealing a forced smile: "No, nothing."

"It's just working overtime for half a month, it's nothing..."

"By the way, Professor, we have completed the basic structure of the electromagnetic railgun, the task you assigned us."

Looking at that exaggerated acting, Lü Yongchang's eye twitched.

Lu Yongchang sighed softly and stood up from his seat with a "concerned" look: "What a pity. I was planning to have you come with me to test the performance of the energy storage equipment, but it seems you need a vacation."

"That's settled then, Professor Yevgeny. You should go back and rest. I'll arrange for someone to continue the second half of the electromagnetic railgun development."

Yevgeny stood there, looking completely bewildered: "???"

this?!

The energy storage device is complete?!

He was completely dismissed in just one sentence?!

Are you kidding me!

He would die with regrets if he didn't see the electromagnetic cannon fire!

He quickly stretched out his large, calloused hand and vigorously rubbed his cheek: "Professor Lü! You've misunderstood me!"

"I feel great right now, I don't need any rest at all!"

Lu Yongchang's eyes were full of smiles.

Because the research and development progress was perfectly in line with expectations, Lü Yongchang, in a good mood, joked with Yevgeny, "Really?"

"Don't worry about my opinion. If you're tired..."

"No, no, no!" Yevgeny blurted out in his native language, "Professor, believe me, I'm absolutely not tired!"

Hearing the rapid trilled "r" sounds, Lü Yongchang laughed heartily and walked out of the office.

Yevgeny was left standing blankly at the doorway, watching Lü Yongchang's receding figure.

"What are you standing there for?" Lu Yongchang's voice came from ahead. "Come with me to the testing ground."

The confusion in Yevgeny's eyes vanished instantly. He responded and chased after Lü Yongchang.

……

"Professor, is this a superconducting magnetic energy storage device?"

Upon seeing the enormous device made of coils on the test site, Yevgeny looked somewhat surprised and asked in a low voice.

"That's right." Lü Yongchang patiently explained the reasons for choosing this device.

"……I see!"

Yevgeny suddenly realized: "In that case, with room-temperature superconducting technology, this thing is indeed the perfect energy storage device for electromagnetic guns."

Lu Yongchang nodded slightly, and without further ado, asked directly, "Zero, has the electromagnetic railgun simulation calculation been completed?"

"Calculation complete!"

A voice rang out from the speaker, and then the holographic image displayed the calculation results in front of the two people.

Looking at the requirements for energy and energy storage equipment, Yevgeny clicked his tongue slightly.

These staggering figures... he wouldn't have dared to even imagine them before!

but now……

Yevgeny looked at the device in the distance, a hint of anticipation in his eyes.

Perhaps he will be able to see the giant ships and cannons of his dreams!

"Zero, begin the first charge/discharge test!"

Upon seeing the data, Lü Yongchang raised an eyebrow and spoke directly.

The next moment, the lights in the arena dimmed for a split second.

Not only the lights in the test site, but the lights in the entire Mars City dimmed a bit for a moment!

That's the result of the superconducting magnetic energy storage device charging!

Clearly, the fusion reactor in Mars City is not powerful enough, otherwise this situation would not have occurred.

This is no way.

When it was originally designed, the power of the fusion reactor in Mars City was even less than that of the fusion reactor inside the Luan Bird Starship.

"Professor, charging is complete!" Zero said in a calm voice. "The energy storage target has been achieved!"

This is just the first step.

For electromagnetic railguns, the most challenging aspect for energy storage devices is actually the power of energy release!

"Zero, begin releasing energy!"

The moment the words were spoken, the curve in the holographic image shot up instantly, and then quickly fell back down.

On the smooth curve, a sharp peak appeared that pierced the sky!

"Professor, the energy release is complete."

"Instantaneous power has met the standard!"
