Inside Mars City One, Lü Yongchang frowned deeply in the laboratory.

The principle of an electromagnetic railgun is very simple; its basic principle is magnetic force.

In the simplest terms, a magnetic field exerts a force on charged objects.

At the microscopic level, this force is known as the Lorentz force; at the macroscopic level, it is the Ampere force.

In the 19th century, Faraday discovered electromagnetic induction, and in the early 20th century, some people proposed the idea of ​​launching projectiles using Ampere's force.

Although the principle is simple, developing an electromagnetic cannon suitable for interstellar warfare is not a simple task.

Human civilization has never stopped researching electromagnetic railguns, but they have never been able to replace gunpowder weapons.

To adapt to interstellar warfare, all Lü Yongchang needed to do was increase the power of the electromagnetic cannon.

The power of an electromagnetic railgun depends primarily on the mass of the projectile and its initial velocity after leaving the barrel.

Thinking of this, Lü Yongchang turned to Professor Yevgeny beside him and asked.

"Yevgeny, what's the power level of the most powerful electromagnetic railgun currently available?"

Upon hearing this question, Yevgeny answered without hesitation, "Professor, if I may be so bold, those electromagnetic guns are very weak."

"They might be able to replace some of the functions of artillery shells on Earth, but in outer space, their power is still too weak!"

"What do you mean?" Lu Yongchang raised his eyebrows slightly and asked again.

Yevgeny shrugged and gave some data: "The most powerful electromagnetic gun at present can only accelerate a projectile of about 10 kg to a speed of about Mach 10."

"Of course, this is also because the development of various weapons projects came to a standstill after the solar crisis."

"After all, there was no such thing as controlled nuclear fusion before."

Lü Yongchang nodded thoughtfully.

"Mach 10...that's definitely a bit slow."

A muzzle velocity of 3400 m/s... in outer space, it's practically like a snail.

It can't even match the speed of the Luan Bird Starship!

"Professor, what do you think we should aim for?" Yevgeny's voice interrupted Lü Yongchang's thoughts.

"The target...muscle velocity must be at least 5000 km/s."

"..."

The laboratory was quiet.

All the researchers, including Yevgeny, stared wide-eyed at Lü Yongchang.

"An initial velocity of 5000 km/s?!" Yevgeny gasped, his face slightly flushed as he looked at Lü Yongchang. "Professor Lü, do you think this is even possible?!"

Lü Yongchang remained silent for a while.

Instead of directly answering Yevgeny's question, he shouted at the camera next to him.

"Zero, simulating under ideal conditions, how high can the initial velocity of the electromagnetic gun be increased by the fusion reactor on the Luan Bird Starship?"

The holographic image unfolds instantly.

A string of data flashed across it.

Zero replied in a calm tone, "Professor, according to calculations, if we don't consider starship propulsion and other issues, it can accelerate a standard projectile to 20,000 kilometers per second."

“Look.” A faint smile appeared on Lü Yongchang’s lips. “5000 km/s is actually an understatement.”

Yevgeny watched the calculation process on the holographic image and swallowed slightly.

"Professor, you are even more... insane than I imagined!"

As he spoke, Yevgeny looked at Lü Yongchang with eyes full of admiration.

According to Zero's simulation, to achieve this effect, the entire Luan Bird Starship would essentially only have one function left.

fire!

As a staunch believer that "caliber is justice," Yevgeny swore that even he had never imagined such an outrageous thing!

Lü Yongchang happily accepted Yevgeny's 'praise': "Calm down, the Luan Bird Starship is still too small."

"If you enlarged the starship tenfold, you probably wouldn't find it so exaggerated."

Yevgeny looked at Lü Yongchang with a somewhat numb expression.

Is this even human language?

He rubbed his temples, looking troubled, and skipped the topic: "But even if the energy problem is solved, we don't have the energy storage equipment to support its launch."

This is the biggest problem limiting electromagnetic railguns.

Energy storage, needless to say, electromagnetic railguns require extremely rapid energy release and recharge technology.

The issue of energy release is related to the power of electromagnetic railguns.

Electromagnetic guns require instantaneous power, and energy storage devices need to release their stored electrical energy all at once in a very short time.

The charging issue is crucial to the electromagnetic railgun's sustained combat capability.

You can't expect to need several hours of buffer time after firing a shell, can you?

Of course, in addition to having the ability to charge and discharge energy quickly, energy storage devices also have another essential requirement.

The capacity of energy storage devices.

To meet all three requirements... Yevgeny is certain that humanity currently does not possess such an extraordinary energy storage technology.

Faced with Yevgeny's doubts, Lü Yongchang calmly nodded: "Don't worry, there's no need to worry about energy storage technology."

“I already have a solution.”

"What you need to do is complete the basic architecture of the electromagnetic railgun."

Yevgeny: "...???"

At that moment, his eyes were filled with self-doubt.

When did he take on such an easy R&D task?

Once the basic structure of the electromagnetic railgun is completed, is that all?

He took a deep breath and nodded silently.

"Professor, I'll listen to you."

Lu Yongchang smiled and patted the strong back of the Soviet man in front of him: "Keep it up."

"I hope to see results within half a month."

After saying that, he turned around and walked quickly toward his office.

He needs to bring to life the inspiration that flashes through his mind!

Yevgeny's face stiffened: "..."

Now, he decided to retract his earlier exclamation.

Is this even a task a human could accomplish?!

"Wait, wait a minute, Professor, half a month? Are you sure you didn't get the time wrong?!"

Yevgeny followed closely behind Lü Yongchang, asking the question with a hurried expression.

Lu Yongchang naturally did not stop walking; he simply waved his hand and left a message.

"Believe in yourselves, you can definitely do it."

Watching Lü Yongchang's departing figure, Yevgeny's eyes twitched violently twice.

"Calm down, Professor Yevgeny." A researcher from the former Xia Kingdom stepped forward and patted Yevgeny on the shoulder reassuringly. "You'll get used to it."

"Professor Lü's research tasks have always been like this."

"For the next two weeks, we can just sleep less."

Yevgeny turned his head and stared blankly at the smiling researchers.

Is this how you usually are?

Several researchers with yellow skin nodded with smiles on their faces and said in unison, "Of course!"

Yevgeny's face grew increasingly pale.
