My physics masters couldn't possibly be grand mages.

Tesla did not respond; he was still thinking, but this thinking time was short-lived. When he looked up again, light reappeared in the deep smoke.

Xia knew he had a solution.

"What if we use electricity?" Tesla asked. "What in this world is faster than electricity?"

He slowly raised his hand and continued the steps he had just taken, but this time he created a "container" filled with a thin layer of "magic".

"If we consider magic itself as a superconductor," Tesla murmured, "then it can be used both as a conductor and as an 'energy storage device.'"

His idea was simple: if magic energy storage couldn't meet the requirements, then he would convert magic energy into electricity and then store it.

He silently converted magic into electricity using the transformation rune and input it into the magic container.

Lightning crackled within the container. Char could almost hear the crackling sound, but it wasn't actually very loud.

Then, Tesla once again aligned the track with the tree not far away and issued the launch command.

Under the manipulation of the perception runes, the surging electricity poured into the two virtual tracks like a wild horse.

The metal ball that was placed there was instantly launched away by the terrifying force.

"Bang!"

The bullet pierced the air and embedded itself deeply in the tree.

The open space was quiet for a while, and Xia quickly stepped forward to examine the tree.

"It worked?"

Tesla turned to Einstein. "How's the data?"

He knew that Einstein had been using his mental energy to focus on the magic and would also roughly calculate the data.

"It should be supersonic, around Mach 1, how's the energy consumption?"

"Including track shaping and such, it's close to six hundred," Tesla said in a low voice. "But the track itself can actually be reused several times, so on average, it should be around five hundred each time."

He was clearly still somewhat dissatisfied, "The bullet velocity can't even compare to a rifle, so the cost-effectiveness isn't very high."

Tesla paced around the yard, and suddenly, as if struck by a thought, he murmured to himself.

"The larger the capacitor, the slower it discharges. What if we connect two capacitors in parallel?"

"Parallel connection?" Char repeated, his mind racing. "Two capacitors discharging together?"

"Yes." Tesla had already turned around. "The discharge speed of a single capacitor is limited by its own channel. Connecting two in parallel, triggering discharge simultaneously, doubles the instantaneous power output, but the discharge time remains the same."

Einstein silently watched Tesla without saying a word.

Tesla raised his hands.

Magic seeped from the fingertips of both his hands simultaneously, condensing into two fist-sized orbs of light in front of him.

Two virtual tracks unfolded before him once again.

This time, instead of connecting the capacitors and the track with a single loop, he drew a magic branch from the output of each capacitor, and the two branches met at the starting point of the track.

"Parallel connection complete," Tesla said softly, as if confirming to himself.

He raised his hand, took out an aluminum bullet from his pocket, and wrapped it with magic. It was very thin, but enough to isolate the bullet from the track, achieving "magnetic levitation"-style contactless acceleration.

He placed the bullet at the starting point between the two light bands.

"Charging".

Tesla continuously channeled the magic power from his sea of ​​consciousness into the two capacitors. Under the influence of the conversion runes, the magic power was transformed into electric current and injected into the sphere of light.

Occasionally, tiny electric arcs would jump across the surface of the sphere, emitting a slight hissing sound.

The whole process lasted about four or five seconds.

He raised his right hand, making a gun gesture, pointing his index finger at the old oak tree twenty meters away, and his thumb upward.

His mental energy touched the "Perception" rune connecting the two capacitors.

In that instant, Char saw the two orbs of light flash simultaneously.

Then--

"call out-"

It sounded like cloth being torn, clean and crisp.

Char's eyes didn't catch the trajectory of the bullet. He only saw a cloud of sawdust explode on the tree trunk.

Einstein walked toward the oak tree.

There is not one hole in the tree trunk.

It was a fist-sized, through hole. The bullet entered from the front and exited from the back.

Einstein located the direction from which the bullet was launched on the back of the tree trunk. He visually estimated the trajectory of the bullet.

He picked up a twisted and deformed piece of metal from the grass in the distance.

It was that aluminum bullet.

But it was flattened, and there were traces of melting on the surface.

Einstein held it up to his eyes and looked at it for two seconds, turning it over and over.

"Mach 3," Tesla said, walking up to Einstein, his tone as calm as if he were reporting a temperature. "The aerodynamic melting of the projectile's surface indicates a speed of at least Mach 2.5. Considering the penetration depth and trajectory straightness, Mach 3 is a fairly reliable estimate."

Xia opened his mouth, but couldn't say anything for a moment.

Mach 3. Three times the speed of sound. Over one thousand meters per second.

"What about the consumption?" Xia asked.

"Including the pre-charging of the two capacitors, orbit shaping, and this launch..." Tesla silently estimated, "The total magic consumption is about 620."

"Similar to a single capacitor?" Xia Ya continued to ask.

"Pretty much." Tesla took the aluminum bullet from Einstein's hand, weighed it in his hand, and said, "With two capacitors in parallel, the same power consumption increased the speed from Mach 1 to Mach 3."

He lowered his head, looked at the flattened aluminum bullet, and remained silent for two seconds.

"Slightly faster than a sniper rifle, and while not the most ideal electromagnetic cannon, it's passable for a Tier 3 'prototype'."

"Just add an aiming spell one last time," Tesla commented. "Mental power can detect the surroundings in a wide area. Adding a rune to perceive the outside world, combined with vision, should make creating a magical aiming device no problem."

"This kind of magic is also easy to upgrade later," Einstein commented.

Tesla nodded, clearly agreeing with Einstein's statement.

"Lengthen the track, make the supercapacitor bigger, increase the input of magic and the charging time, but I don't know how much it can increase."

He touched his chin.

"Many spells, such as [Burning Hand], only increase the attack range and duration when the magic power output is increased due to the limited magic power output of the second tier.

However, this electromagnetic cannon operates on a different logic; you can convert magic into electricity and store it, then release it in an instant.

It is one of the few charged spells that allows you to exchange time for damage output.

"So, it can be used as a final, deadly move?" Xia asked.

Upon hearing this, Tesla turned its attention to Char.

"That's right, but the biggest prerequisite right now is... for you to learn the runes needed for 'conditional judgment'."

Einstein's gaze shifted to Char, who swallowed hard.
