Mastering Thunder from Hogwarts

In the next few days, Anduin began to modify and optimize the new talisman right after class. With the development process of the first two talismans, Anduin did not encounter any difficulties. Soon he was working on the basis of the original talisman.

On, 4 rune combinations were transformed.

At the end of October, he began intensive experiments.

The test method is also very simple. It is mainly divided into two steps. The first step is to test whether the spell is harmful to the living body. At this time, the mouse gentleman will appear. First, cast the spell on the mouse several times, and then observe whether there is any abnormality.

, if there are no problems, go to the next step. This is mainly because he was almost killed by his reckless experiment last time, so for the sake of safety, he is going to add this link to all future experiments.

The second step was to start the actual test. He named the talisman he modified as the 'Sound Wave Expelling Curse', cast the spell on himself, and then listened to the natural sounds around him. If he couldn't hear it, he started to increase the power to let Hagrid.

I yelled a few times for help, and after it was also effective, I started to test the 'Echo Spell'. The frequency of ultrasonic waves is very high, so in theory if it can block ultrasonic waves, it should be able to block all sound waves. Finally, I just need to test it again.'

Infrasonic spell'.

"The four newly combined talismans can all block natural sounds." Anduin thought after testing, "But only the 3rd talisman can completely shield ultrasonic waves, so let's use this talisman as the main body for optimization."

Anduin did not rush to try the 'Infrasonic Wave Curse' experiment. He was not prepared to try the feeling of being attacked by his own talisman again, so he carried out secondary optimization based on the best-performing set of talisman combinations. He decided

After preparation is complete, conduct the final test.

After several days of adjusting the spell and repeatedly testing ultrasonic waves, Anduin finally made up his mind to start testing the infrasonic spell.

"On October 31st, at 19:38 pm, the recording of the second test of the infrasonic curse begins." Today is Halloween, and Hogwarts has prepared a sumptuous Christmas dinner for the students, as well as ghost performances and other such things, but Andu

Since he was not interested in any of these, he decided to try the infrasonic spell again.

This time he was prepared for everything, and even prepared two bottles of healing potion for himself. At the same time, he asked Hagrid to help keep an eye on him from a distance. If anything unexpected happened, he could come over immediately to help.

"Huh!" Anduin exhaled slightly, adjusted his breathing and thoughts, and calmed himself down completely.

Pulling out his wand and pointing it at himself, Anduin steadily and accurately cast the 'silencing spell' that had been tested many times.

"Ah ah ah." Anduin shouted several times to confirm that he heard nothing, and then began to experiment with the infrasonic spell.

He waved the wand lightly, and the lines of the spell condensed on the tip of the wand. He flicked his wrist slightly, and then a wave of magic spread from the tip of the wand. But at this time, Anduin heard no sound, and there was no reaction on his body.

It even made Anduin doubt whether the spell was successfully cast.

With another wave of the wand, Anduin extinguished the spell. To confirm, he looked at the rat in the cage next to him. Sure enough, he was bleeding to death from all his orifices.

"It seems to have been successful. The effect of the Silencing Curse is also very good." Anduin muttered to himself excitedly, but found that he did not make any sound. Only then did he realize that the effect of the Silencing Curse was not over yet.

After seeing the condition of the test subject and confirming that the infrasonic curse had indeed worked, Anduin became bolder and decided to continue testing the effect of the 'infrasonic curse'.

But at this time, Hagrid ran towards him and tried to say something to him. Anduin couldn't hear anything at the moment, so he had to quickly remove the sonic banishing spell on his body.

"What's wrong Hagrid? I just put a spell on my body and I can't hear you." Anduin could finally hear his own voice at this time.

"I want to say that I have to leave for a while. Dumbledore just suddenly notified me and asked me to find him quickly." Seeing that Anduin finally reacted, Hagrid finished his words quickly, and then picked up his

Little Red Umbrella ran towards the castle in a hurry.

Anduin saw Hagrid's hurried look and didn't know what was going on. He shook his head and decided not to worry about it. After testing, the sonic expulsion spell was very effective, so he decided to continue the experiment.

What he didn't know was that just tonight, a major event happened that changed the entire British wizarding world.

At this time, Anduin was still happily testing his spell.

"It seems that the effect of the infrasonic spell will attenuate with distance. It will cause a strong interference effect within ten meters. After more than ten meters, the mouse will not die. If it is further away, it will only receive some interference?" An

Du Yin excitedly recorded the experimental data in his notebook.

After testing, the infrasonic spell will cause strong damage within 5 meters and has the strongest interference ability. The killing effect will be weaker around 5 to 10 meters, but the interference effect is still good. The further the distance is, the worse the effect will be. Anduin watched

The little mouse 30 meters away, now under the influence of the infrasonic spell, was just squeaking and spinning nervously in the cage.

"Human beings have stronger resistance to sound waves. It seems that after it exceeds 10 meters, the interference to humans will decrease even more?" Anduin continued to summarize.

After completing the experiment that he had been thinking about, Anduin stretched out in high spirits. It was almost late at night, and Hagrid had been gone for a while. He didn't know what the guy was busy with.

Without thinking too much, he was very satisfied with tonight's experiment, just as satisfied as he had solved the Mathematical Olympiad problem that the whole class could not solve. He lay on the bed in a happy mood and fell into a deep sleep.

And the shocking news came the next day.

The next morning was a weekend. Anduin and Charles came to the castle auditorium in high spirits after finishing their morning exercises. At this time, they found that the atmosphere in the auditorium was different from usual. Almost all the little wizards were not eating.

, everyone was discussing something heatedly, and the sky was filled with owls, which kept dropping letters and newspapers to the little wizards.

"Anduin, Anduin, come on!" Vivian spotted Anduin and shouted at him.

"What happened? Why are everyone so excited?" Anduin asked confused.

"Oh my God, haven't you heard yet?" Vivian said with a shocked face at this time, "The mysterious man fell. It is said that he was killed by a Boy Who Lived! Early this morning, the Daily Prophet reported

The news was announced and I received a letter from home confirming it.”

"What?" Anduin was shocked and snatched the newspaper from Vivian's hand.
