Railgun

Looking down at the nine Silver Soul Coins in his hand, Xu Yuan suddenly had a bold idea.

How had Misaka Mikoto used the Railgun in A Certain Scientific Railgun in his previous life?

Xu Yuan quickly shut the door, sat on the floor, and sank into thought.

The so-called Railgun.

It was a launcher that used immensely powerful electromagnetism to fire projectiles made of conductive material, with many advantages.

Great power, long range, high accuracy, and low cost were merely the basics.

Although Misaka Mikoto's Railgun had no metal rails, she herself could generate extremely high voltage to replace them, making its principle equivalent to that of a railgun.

At that thought, Xu Yuan's heart suddenly surged with excitement.

Could he recreate it?

The Elemental Canon martial soul allowed him to control the powers of all kinds of elemental attributes, and lightning was one of them. Lightning and electricity were inseparable.

Furthermore, his First Spirit Ring skill could further enhance the elemental power under his control. In theory, it should be possible.

As for the principle, it was simple—basic high school science knowledge.

Simply put, he would first extend his right hand, then use elemental power to create a powerful magnetic field running from top to bottom in one direction and perpendicular to his right hand.

Then he would throw a conductor into the magnetic field.

Next, he would use lightning-element power to make an electric current pass through the conductor from left to right. Once the current and magnetic field were powerful enough—

The conductor could be accelerated beyond the speed of sound over a very short distance, unleashing extremely destructive force!

Of course.

The principle was one thing; putting it into practice was difficult.

And the hardest part was instantly unleashing a current like Misaka Mikoto's—one roughly equivalent to ten to the tenth power amperes!

Xu Yuan's idea was compression, using quantitative change to trigger qualitative change.

He would compress Thunder Curtain's ten-square-meter range to within roughly half a meter around his body.

No sooner thought than done.

Very soon, crackling lightning filled the entire hall.

When he was fully focused, time passed quickly.

Without even noticing time passing, five shichen went by.

During that time, Xu Yuan went to the cafeteria for dinner and extended his room rental until midnight before returning to continue his exploration.

The process was difficult.

Once lightning was unleashed, it was hard for Xu Yuan to control it again. Yet if he did not release it, its power would be greatly reduced.

It simply could not meet his requirements.

However, Xu Yuan soon solved this problem.

Through experimentation, he discovered that while using his First Spirit Ring skill, his control over elemental power increased dramatically.

Even attacks he had already released could be forcibly recalled.

If he recalled the attack at the instant it was released, condensed and compressed it together, then unleashed it again, he could meet the requirements for using the Railgun—and perhaps even exceed them.

Honestly.

Based on what Xu Yuan had learned in his previous life, this was somewhat fantastical. But this was a fantasy world, so it was perfectly normal.

Around eleven at night.

Xu Yuan stood in the room, turned sideways toward an iron humanoid target. He extended his clenched right fist, placed his thumb beneath his index finger, and rested a Silver Soul Coin quietly between the junction of his two fingers.

Ding~!

With a soft chime, the Silver Soul Coin flipped as it flew into the air.

The spirit ring circling his body suddenly flashed, and countless silver-white bolts of lightning immediately spread outward from Xu Yuan's body like clawing beasts.

The Silver Soul Coin fell.

Whoosh!

A silver-white beam abruptly shot from Xu Yuan's fingertips, instantly piercing through the iron humanoid target and passing through the Training Hall wall before vanishing from sight.

All that remained was a sizzling current and rings of circular sonic boom clouds.

The breeze it kicked up made Xu Yuan's clothes billow.

Railgun!

After a long while.

Staring at the hole that had pierced straight through the humanoid target, then through it at the wall behind it that had also been penetrated, Xu Yuan's gaze turned blank.

He had expected this move to be powerful, but he had not expected it to be this powerful!

Slowly exhaling a breath of stale air, Xu Yuan wore an excited expression as he prepared to try again, only for the tightly shut door to be violently flung open from outside.

A middle-aged teacher in his forties appeared in the doorway. He stared at Xu Yuan inside with shock in his eyes, his face full of disbelief.

"What did you just do?"

He had been yawning in boredom next door and was just about to use the restroom when a silver-white beam suddenly passed through the wall and shot right past him.

It then pierced through the wall on the other side and flew outside the Training Hall.

It even shot through the trunks of several trees in succession before finally lodging inside one of them and coming to a stop.

This was the Training Hall, not the Soul Fighting Arena. Hardly anyone came here normally, and Xu Yuan had been the only one using it today.

So the moment the incident occurred, he came to Xu Yuan's training room.

So close!

Just barely!

Given the destructive force displayed by that silver-white beam, if his urge to urinate had come just a little earlier, it might not have been only the walls and trees that were pierced.

He had never imagined that he could nearly lose his life inside Spirit Academy.

At this point, how could he still feel sleepy? He had already broken out in a cold sweat.

"Uh."

An awkward smile appeared on Xu Yuan's face. "If I said I hadn't expected this either, would you believe me?"

Seeing Xu Yuan's height of just over one meter, the teacher frowned slightly and looked around.

Common sense told him that someone else must have launched that attack.

But apart from Xu Yuan, there was not another person in sight. This...

"Was that silver-white beam just now released by you?" the teacher asked doubtfully after calming down.

"It was."

Xu Yuan nodded in confirmation.

The confusion in the teacher's eyes deepened. In his view, an attack with such destructive power was simply not something a little spirit master like Xu Yuan could unleash.

After thinking for a moment, he directly told Xu Yuan to return to his dormitory, then shut the Training Hall doors and headed straight for the dean of studies' office.

He needed to report this matter to his superiors.

As for that.

Xu Yuan was somewhat nervous as well. Before leaving, he looked at the holes in the wall and wondered whether that teacher intended to make him pay compensation.

He had no money!

He returned to the dormitory, filled with worry.

The moment he unlocked the door with his key, a snowy-white figure entered Xu Yuan's sight.

She was a girl with an absolutely stunning figure, around twelve or thirteen years old. But people on Douluo Continent generally matured early, so she was already considered a young woman.

Perhaps because she had just finished bathing and had always lived alone, she wore only two pieces of close-fitting clothing that covered the important parts.

Large stretches of her pale body were directly exposed to the air, leaving Xu Yuan frozen on the spot.

Wait, why was his roommate a girl? And she looked so much older than him?

Xu Yuan saw her, and naturally, she saw Xu Yuan as well.

She looked Xu Yuan up and down at his height of just over one meter, then lightly curled her lips.

"Just a little brat. What are you staring at?"
