Mastering Thunder from Hogwarts

Taking back his glasses, Anduin didn't have time to waste time here with Vivian. He had more important things to do. He then said goodbye to Vivian and quickly returned to the Forbidden Forest cabin.

Today he was going to complete the research and experiment on another of his spells, which was the infrasonic spell that had the opposite principle of the echo spell.

The Echo Spell emits high-frequency ultrasonic waves, which will be refracted and reflected along the original path after contacting an object to detect objects passing along the way. Its main application is for reconnaissance and exploration.

Infrasound waves, which have the opposite principle, are ultra-low-frequency sound waves. Because they vibrate at a similar frequency to the organs of a living body, they easily form resonance and can directly affect the nervous system of the living body. High-intensity infrasound waves are very lethal.

exaggerated.

In his previous research, Anduin had already overcome the difficulty of adjusting the frequency of sound waves. Since increasing the frequency was okay, lowering the frequency was also no problem.

In recent days, Anduin has been developing and experimenting with related spells.

"Next is the 33rd 'Infrasonic Spell' test. The spell combination is a triangle. The test time is October 14th at 16:37 pm." After Anduin wrote this in his notebook, he carried a small

The mouse's cage came outside the house.

Since he was testing a killing spell, Anduin prepared a lot of rats as test subjects.

Pulling out the wand, Anduin recalled the structure of the talisman that needed to be tested, controlled the magic power to shape the talisman at the front of the wand, then brought the wand to the mouse cage and tapped it gently to activate the talisman.

"Buzz..."

I heard a piercing and sharp sound erupting from the tip of the wand. Anduin was caught off guard, and his whole body was numb from the shock. He could only hear tinnitus in his ears, and then there was an extremely indescribable feeling of nausea.

Come up.

"I can't help it..."

Anduin couldn't bear it anymore. He held on to the wooden fence next to him unsteadily, bent down and vomited. Tears and snot flowed from his nose, and he felt extremely uncomfortable all over his body.

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

He shook his head vigorously and felt that the dizziness gradually disappeared. At this time, Anduin quickly ran to the basin in the house to wash his face, then walked to the mirror and observed himself carefully.

"Fortunately, my eyes are slightly red, my vision has not been affected, my hearing, um, has gradually recovered, my sense of taste is normal, and my perception and touch have become normal. This good guy almost gave me away." Anduin checked in the mirror.

Thinking of his own situation, he said with lingering fear.

"The good news is that the magic text combination of this spell has been found, and its effect is outstanding and its interference ability is extremely strong. The bad news is that this spell does not seem to distinguish between friends and foes, and the caster of the spell is the closest, so it will kill the enemy first.

It's really a headache to hurt yourself." Anduin summed up the spell experiment and said to himself.

"By the way, where's the mouse!" Anduin suddenly realized that he still had an experimental subject that he had not observed, and hurriedly ran outside the room.

Walking to the cage, Anduin lowered his head, only to see that the little mouse that was the test subject was bleeding from seven holes and had completely lost its life breath.

"The effect of this spell is a bit ridiculous." Looking at the mouse that was shocked to death by this spell, he couldn't help but feel a little scared.

If the effect of this spell had been stronger, he might have been killed. Even if he wasn't killed directly, it might have caused irreparable damage.

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

What should we do next? The structure of the spell has basically been determined, but we can no longer test it. This spell is simply a self-destruction spell, damaging the enemy by one thousand and damaging itself by eight hundred. If we stop here and stop studying, Anduin will be a little uncomfortable.

I'm willing, it seems I have to find another way.

"If you use 'ear plugs' to block your hearing, will you not be affected by infrasound waves? That's not true. Infrasound waves are not just sounds, they are sound waves that directly penetrate into the living body and cause damage." An

Du Yin frowned and thought about various possibilities.

"I don't know if using 'Silent' or 'Whispering Curse' will 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 really a headache. Before developing the spell, I don't know.

Come up with the counterspell first." Anduin debated whether to try it again.

Anduin hesitated for a long time, but the new talisman was right in front of him. It was too uncomfortable to just look at it but not use it. In the end, he decided to try it again.

"Just in case, the magic output during the test will be reduced by 70%."

After Anduin thought clearly, he swallowed, then pointed the wand at himself, 'Close the earplugs and listen', 'Silent', 'Quiet spell', all kinds of spells he knew that could silence or reduce the volume for free.

Throw it on your body.

He doesn't plan to try the spells one by one. If it works, he can then identify which spell is effective. If it doesn't work, he can eliminate all the spells.

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

‘Ouch!’ The figure next to the hut once again held on to the railing and vomited.

"The reaction is not as strong as last time, but it is most likely due to the adjustment of magic power. In other words, these magic spells are basically useless?" Anduin recovered much faster this time, and he concluded immediately after a slight adjustment.

Let’s start with the experiment just now.

"It seems that we have to develop another talisman that completely isolates sound waves. It's really troublesome!" Anduin thought a little frustrated. This experiment gave Anduin hope and gave him a big problem. For a while,

He had no idea at all.

"Forget it, let's ask Professor Bones later tonight if he has any good ideas." Anduin thought depressedly.

At this time, Charles had also completed the day's training and was walking over from a distance covered in sweat. Previously, because Anduin had been doing spell experiments recently, he had sent Charles to a place far away from the hut in the past few days.

train.

Now, Charles trains and eats with Anduin every day. He is much stronger and his energy is much better.

"What does it smell like, Anduin, what did you do here just now? It smells sour and there is a dead rat." Charles asked without knowing why.

"It's nothing. I just did a little experiment and something went wrong. I'm just about to clean it up." After that, Anduin waved his wand to expel all the air around him, then used a cleaning spell to clean up the dirt, and then dealt with it.

Drop that time mouse.
