Hogwarts: My name is the Unforgivable Curse

As Baron spoke, he opened the suitcase that he had kept at his feet: "Let me show you the device I made myself - don't worry, it's an ordinary spider inside, not an Acromantula."

Inside the box was a glass jar the size of a Quaffle. Inside was a common black spider, which was lying sickly at the bottom of the jar. There were also a bunch of small flying insects that were probably food rations next to it.

"In order to ensure the spider's emotional stability under normal circumstances, I applied some albizia flower juice on the inside of the cover - that is the main ingredient in the joy potion, which helps to maintain calmness."

Balon explained as he placed the jar on the table.

"Nothing else but that?"

"It's gone for now."

"let me see……"

The device in front of her is likely to be a life-saving straw for Muggle-born students for quite some time in the future, and the key to exposing the conspiracy of the school board. Faced with such an important thing, Avada must devote herself to thinking carefully - according to the standards He should also take a sip of intelligence-enhancing potion, but unfortunately he is currently in the cultivation stage and cannot come.

He put down the knife and fork in his hand, took out the wand and pointed it at the poor spider. He closed his eyes, frowned slightly, and carefully sensed the spider's spiritual power and vitality. After a while, he finally regained consciousness. He looked up at Baron.

"This kind of spider has a strong ability to sense the basilisk, with a radius of about fifty meters. If the basilisk happens to be active, the range will be even larger. In that case, it will basically cover most of the castle. Personally it doesn’t mean much…”

Avada tapped the glass jar with her wand: "I suggest adding a magic that suppresses the dispersion of mental power to the jar to limit the range of the spider-sensing basilisk... A radius of twenty or thirty meters is enough."

"And the spider's other stress behaviors must also be restricted, and its earthquake resistance must also be added..."

"Oh, by the way, students wearing this device may not always be able to pay attention to the spider's movements. They also need to arrange a magic to detect the spider's status. Once the spider is found to be in panic, an alarm will be issued immediately..."

"And it has to be as portable and less conspicuous as possible. The jar is a bit too big now, but it still has to leave the spiders with the necessary living space. This aspect may be solved by choosing the species of spider..."

"Well, a very valuable proposal..."

At some point, a note appeared in Barron's hand. He held a pen in one hand and wrote down the suggestions provided by Avada: "But in this way, will it be a little difficult to make a single device? This thing requires a lot of effort." Let every Muggle-born student have one."

"not tall."

Avada shook her head: "Give me half an hour, I can develop the matching magic, and the difficulty of casting the spell should be controlled at the level of a third or fourth grader. It would be enough to ask a few more people to make it."

"So fast?" Baron looked at Avada in surprise: "Isn't your mental power still recovering? Don't use intelligence enhancers and the like..."

"The development of this small spell does not require intelligence enhancers."

Avada smiled and then analyzed: "If you want to choose spider species, you can go to Professor Kettleburn or Hagrid and ask them to provide some reference opinions, and then directly contact the store in Diagon Alley for bulk supply... click here In terms of speed, one Christmas vacation is enough time to make all the devices that all Muggle-born students in the school will use."

He finished the food on the plate in front of him in three mouthfuls, and then stood up directly: "Without further ado, I will develop the relevant spells now. Lend me this jar first."

"Um."

When talking about such an important thing, Baron suddenly lost his appetite: "Then I'll go find Professor Kettleburn and ask about the spider."

"good."

Avada nodded: "We have to do it as soon as possible - try to build the devices for all the Muggle-born students who are staying in the school before Christmas, and save one more if possible."

"Now the basilisk's eyes should be equipped with a transparent layer similar to glasses, so that its glare will not kill, but only petrify. And if the guys on the school board see that their threats are not effective , if there are still a large number of Muggle-born students staying in the school, maybe they will really take off the blindfold of the Basilisk and let it go on a killing spree. Anyway, the so-called Will of the Castle is responsible... We must seize the time."

"They should be less extreme for a while."

Balon said comforting words, but his expression did not slow down at all: "After all, Dumbledore cannot sit back and watch these things happen. They lack a backer who can confront Dumbledore head-on..."

"It'll be there soon."

Avada looked around to make sure no one was paying attention to their conversation before whispering to Balon: "Snape has confirmed with me that the man behind the whole thing is Voldemort himself - don't be too surprised yet. Did you also see the scene where he split his soul? He had done the same thing before, which led to the existence of more than one Voldemort in the world. And each Voldemort's soul may have the possibility of independent resurrection. Just like Professor Baker.”

"If they really resurrected Voldemort quietly during the occupation of Hogwarts, things would be really troublesome."

"Does Dumbledore know?"

"I know. This is what he asked Professor Snape to convey to me."

"That's good."

Baron breathed a sigh of relief: "At least the situation is still under control... Wait, didn't you say before that Professor Snape made an unbreakable oath to the school board? How did he pass on so much information to you?"

"To be honest, I don't know. He doesn't seem to care about that oath at all..."

Avada also had a slightly puzzled look in her eyes: "If I had to guess, either he was ambiguous when he swore the oath, which caused a loophole to be exploited, or it was the magical Dumbledore who took action."

"……All right."

Baron also stood up: "Then I won't go back this Christmas. I'll stay in school and make spider devices with you."

"good."

Avada didn't refuse - after all, there were hundreds of Muggle-born students in the school, so it would be too busy for him alone, and besides, Baron's magic level was trustworthy.

"It's Christmas vacation in three days. If we develop the supporting magic today and place an order for Diagon Alley, we can start work tomorrow. That means we have to make about twenty or thirty devices in two days... … It’s a little stressful, but not a lot.”

"And don't forget about distribution - most people now believe that what petrified the students was really the so-called Castle Will. We still have to convince those students that the murderer is indeed a basilisk. Fortunately, the school management We took the initiative to post the list of Muggle-born students, otherwise our workload would have doubled several times... I won't say anything anymore, I'm going to find Professor Kettleburn, you should hurry up."

"good."

Avada nodded and stopped talking. She quickly left the busy common room with the glass jar containing the spider, then found a quiet empty classroom and sat in it.

'If this device can be effectively promoted and completely eliminated, or at least significantly reduced, petrification incidents, it will be almost irrefutable evidence of the existence of the basilisk. At that time, we can force the school board to come forward to explain, and even alarm the entire magical society...'

‘In this way, I don’t even need to come forward to crack the secret room. The people who come to investigate will turn the old pipes upside down, drag out the basilisk and kill it. In this way, the school board's conspiracy will be self-defeating, and Dumbledore can return and cripple the stubborn pure-blood faction... And I can also spare time to study the confession effect and put the Horcrux Diary in the Horcrux Diary as soon as possible. Pull out the soul fragments! ’
