Mastering Lightning from Hogwarts

The Ministry of Magic's so-called security check was, in Anduin's eyes, as simple as child's play. He watched the old wizard in front of him use his wand to cast spells like 'Detect Poison' and 'Curse Revealing' on the alchemical tools in the box. The main problem was that the other party's spellcasting level was very average. Did he really need to cast spells on each item individually? Didn't he know area spells? This truly opened Anduin's eyes.

Anduin dawdled here for more than ten minutes before the other party stopped, panting.

"Everything alright, Perkins?" Arthur asked, looking at the sweating wizard in front of him, and thoughtfully handed him a handkerchief.

"It's fine, but why did you pack so much stuff? It really wore me out." Perkins, with his graying temples, complained a bit, and even gave Anduin a slightly unfriendly glare.

To this, Anduin could only roll his eyes speechlessly. He had been debating whether to develop a special alchemical tool for security checks, but after experiencing such inefficient service, he thought it was absolutely necessary. He planned to start working on it when he got back, to make sure this old man lost his job as soon as possible.

After finally finishing the security check, the two first went to see Vanessa, asking her to look after Ginny and Hogge for a while. The upcoming demonstration wouldn't be convenient with them around.

Afterward, the two finally arrived late at the practice hall, which looked like a large banquet hall. It was brightly lit, with a very high ceiling, and two rows of dummies lined up on both sides for Aurors to practice on.

At this time, there were already many people standing in the practice hall. In the very center of the hall was Minister Baudry, with Amelia Bones, the current Head of the Department of Magical Law Enforcement, and Cornelius Fudge, the Head of the Department of Magical Accidents and Catastrophes, standing in two rows, along with more than a dozen Hit Wizards led by Moody.

Cornelius Fudge, whom he had met once before, had a kind expression and nodded at Anduin with a smile.

There were also many Ministry of Magic employees standing around, who, judging by their clothes, belonged to different departments. There was also Aselia, whom he had just met, standing next to a middle-aged man, who should be an official from the Department for the Regulation and Control of Magical Creatures.

"Sorry, Minister, we're late. The routine inspection took up a lot of time," Arthur said as he entered, leading Anduin to Minister Baudry to report.

"It's alright, we've only just arrived ourselves." Minister Baudry still looked very dignified, then looked at Anduin beside him, "Long time no see. I heard from Moody that the equipment you have is very important for our upcoming operation. After so long, you can still bring us surprises."

What exactly did Moody tell you? It was so sensational. After hearing Minister Baudry's words, Anduin felt a little inexplicable.

Moody next to him looked at him with a smile, and winked at him rather smugly when their eyes met.

"Sorry, I didn't know you valued it so much before, and I can't guarantee whether it will completely satisfy you." Anduin felt that he had to leave himself a way out first, lest he be inexplicably set up by Moody.

"I told Moody not to be too clear in his letter to you." Minister Baudry shook his head nonchalantly. "Today's demonstration requires a certain degree of confidentiality, and please don't publicize today's events afterward."

So that's how it was. No wonder the letter Anduin received was vague. It seemed that everything had been arranged in advance. He didn't know what trouble the Ministry of Magic had encountered that required such secrecy.

"I understand, I will keep my mouth shut. Then, in order not to waste time, shall I start the product demonstration directly?" Anduin looked at Baudry with a questioning look.

"Hmm." Minister Baudry pondered for a moment, then looked at the surrounding crowd, "Amelia, Cornelius, Bianca, you should also take a good look at the equipment provided by Anduin, and see if it has enough value."

The three people next to him nodded with serious expressions, and the man called Bianca was the official from the Department for the Regulation and Control of Magical Creatures next to Aselia.

Then these dozens of people stared straight at Anduin.

Anduin looked around and saw that there wasn't even a table for him to display the equipment, but he didn't care too much. He directly threw out a large table from his space ring, then opened the leather suitcase in his hand and neatly placed the items inside one by one.

"Everyone, I am honored to be able to present the products of Silver Lightning Alchemy Company today." Anduin spread his hands towards the display table and said a very calm opening remark.

Seeing that Anduin remained calm and composed in the face of so many Ministry of Magic officials, the people watching him nodded silently.

"The alchemical products of our company are designed to provide sufficient convenience and guarantee for wizards on the front line. Next, I will demonstrate the functions of these products to everyone one by one."

After saying that, Anduin took out a metal amulet and explained to them, "This is a communication amulet, which can provide information transmission services for everyone. As long as magic power is input into one amulet, the corresponding amulet will flash and vibrate. The current working range can cover the entire British mainland."

"This amulet currently has two working modes, one-to-many communication and many-to-many communication."

"The one-to-many communication function is to set one of the amulets as the main amulet, and then set the remaining amulets as sub-amulets. A stable connection can be established between the main amulet and the sub-amulets, and simple information transmission can be carried out. Next, I will personally demonstrate it to everyone."

Anduin took out five amulets, took one for himself, and then handed the remaining four to Minister Baudry and the other three department heads.

"The one in my hand is the main amulet, and the ones in your hands are the sub-amulets. We can communicate in advance and set instruction codes, such as activating it once to represent safety, activating it twice to represent the discovery of the enemy, activating it three times to represent the smooth progress of the action, and so on."

"There is also an emergency communication module. If the amulet is damaged, or a large amount of magic power is input into the amulet at one time, it will immediately send an emergency signal to other amulets in the communication network. The performance is flashing red light, heating up, and producing a lot of vibration, and the sensing amulet can also point to the location where the emergency signal last appeared."

As Anduin spoke, he input magic power into the main amulet, and then the amulets in the hands of Minister Baudry and several department heads also showed corresponding feedback.

Finally, Anduin input a large amount of magic power at one time, and then the amulets in the hands of the others began to heat up, glow, and vibrate.
