Mastering Lightning from Hogwarts

Taking back his glasses, Anduin didn't have time to waste with Vivian, as he had more important things to do. He quickly bid farewell to Vivian and hurried back to the Forbidden Forest cabin.

Today, he planned to complete his research and experiment on another spell, one based on the opposite principle of the Echo Charm: the infrasound spell.

The Echo Charm utilizes high-frequency ultrasound waves, which reflect back upon contact with an object, detecting objects along the way. Its primary application is for reconnaissance and exploration.

Infrasound, with its opposite principle, uses ultra-low-frequency sound waves. Because its frequency is similar to the vibration frequency of biological organs, it easily creates resonance and can directly affect the nervous system of living organisms. High-intensity infrasound has an exaggerated destructive power.

In his previous research, Anduin had already overcome the difficulty of adjusting sound wave frequencies. Since increasing the frequency was possible, decreasing it was naturally not a problem.

For the past few days, Anduin had been conducting related spell development and experiments.

"Next is the 33rd 'Infrasound Spell' test, the spell combination is triangular, test time is October 14th, 16:37," Anduin wrote in his notebook before taking the cage with the little mouse inside outside.

Since it was a test of a destructive spell, Anduin had prepared many mice as test subjects.

Drawing his wand, Anduin recalled the spell structure he needed to test, controlling the magic to form the spell at the tip of his wand. Then, he brought the wand close to the mouse cage, gently tapped it, and activated the spell.

"Buzz..."

An ear-piercing, sharp sound erupted from the tip of the wand. Caught off guard, Anduin was shaken, his whole body went numb, and his ears were filled with ringing. Then, an indescribable feeling of nausea surged up.

"I can't take it anymore..."

Anduin couldn't bear it any longer. He staggered and grabbed the wooden fence beside him, bending over to vomit violently, with tears and snot flowing freely. He felt terribly uncomfortable all over.

Anduin vomited for at least five or six minutes before gradually recovering, but his head was still dizzy. He had to stand there with his eyes closed for a while before he gradually regained consciousness.

He shook his head vigorously, feeling the dizziness gradually disappear. Then, Anduin hurried to the water basin inside the house to wash his face. After that, he went to the mirror and carefully observed himself.

"Fortunately, my eyes are only slightly red, my vision hasn't been affected, my hearing, um, is gradually recovering, my sense of taste is normal, and my senses and touch are returning to normal. Good thing, I almost sent myself away." Anduin checked his condition in the mirror, saying with lingering fear.

"The good news is that the magic rune combination for this spell has been found, and its effect is excellent, with extremely strong interference ability. The bad news is that this spell doesn't seem to distinguish between friend and foe, and the caster, being the closest, will be hurt first when harming the enemy. This is really a headache," Anduin summarized the spell experiment, talking to himself.

"Right, what about that mouse!" Anduin suddenly realized that he had an experimental subject that he hadn't observed yet, and he quickly ran outside.

He went to the cage, lowered his head, but only saw the little mouse, his test subject, already bleeding from all seven orifices, completely lifeless.

"The effect of this spell is a bit too outrageous." Looking at the mouse that had been vibrated to death by the spell, he couldn't help but feel a lingering fear in his heart.

If the effect of this spell were any stronger, he might have been finished too. Even if he wasn't directly killed, it might have caused irreversible damage.

"I'm still too reckless. No wonder Bones said that testing spells is a dangerous job," Anduin frowned and muttered.

What should he do next? The spell structure was basically determined, but he couldn't conduct any more experiments. This spell was simply a suicide spell, harming the enemy by a thousand while damaging himself by eight hundred. If he stopped researching it now, Anduin would be a little unwilling. It seemed he had to think of another way.

"If I use 'Ears Sealed Shut' to block my hearing, wouldn't I be unaffected by the infrasound? No, that's not right. Infrasound isn't just a simple sound; it's a sound wave that directly penetrates the body to cause damage." Anduin frowned, thinking about various possibilities.

"I wonder if 'Silencing Charm' or 'Quiet Charm' can have any effect. Do I need to conduct another test? I don't know if these spells have the function of eliminating sound waves. It's a headache that I have to create a counter-spell before developing a spell," Anduin struggled with whether to conduct another experiment.

Anduin hesitated for a long time, but a new spell was right in front of him, and it was too painful to only be able to look at it but not use it. In the end, he decided that he still had to try again.

"Just in case, I'll reduce the magic output by seventy percent during the test later."

After Anduin thought it through, he swallowed and then pointed his wand at himself, 'Ears Sealed Shut', 'Silencing Charm', 'Quiet Charm', he threw all kinds of spells he knew that could silence or reduce the volume on himself without holding back.

He didn't plan to test the spells one by one. If this worked, he could figure out which spell was effective later. If it didn't work, he could eliminate all these spells.

Anduin couldn't hear any sound for a while, then he took a deep breath, adjusted the magic output, and activated the spell firmly.

'Puke!' The figure beside the cabin leaned on the railing and vomited again.

"The reaction wasn't as strong as last time, but it's very likely because I adjusted the magic power. Does that mean that these spells are basically useless?" This time, Anduin recovered much faster, and after a little adjustment, he immediately summarized the previous experiment.

"It seems I have to develop a spell that completely isolates sound waves. What a trouble!" Anduin thought dejectedly. This experiment gave Anduin hope, but also presented him with a major problem, leaving him clueless for a while.

"Forget it, I'll ask Professor Bones if he has any good ideas tonight," Anduin thought gloomily.

At this time, Charles had also completed his training for the day and was walking over from a distance, covered in sweat. Previously, because Anduin had been doing spell experiments recently, he had sent Charles to train on his own a little further away from the cabin for the past few days.

Now, Charles, training and eating with Anduin every day, had become much stronger and more energetic.

"What's that smell, Anduin? What exactly were you doing here just now? It's all sour and stinky, and there's a dead mouse," Charles asked, puzzled.

"It's nothing. I just did a little experiment, and something went wrong. I'm just about to clean it up," Anduin said, waving his wand to expel all the air around him, then using a cleaning charm to clean up the dirt and dispose of the dead mouse.
