Chapter 370: Unknown Difficulty

"Subtraction?"

Wade was silent for a moment, lost in thought.

Then he took a piece of paper from the desk and began to write and draw.

Professor Murray looked at it for a while, then showed a relieved and complicated smile.

Applying magic to an alchemical work is not simply a matter of adding spells one after another. The spells will also conflict, weaken, and cancel each other out.

Therefore, most alchemists can only cast one or two spells. For example, ordinary invisibility cloaks only have the illusion spell, which will gradually lose its effect over time, and can also be destroyed by spells or sharp weapons.

Vader has a very rare talent in superimposing multiple spells. Professor Murray was amazed at this time and time again, wondering how he could put together so many spells so exquisitely.

He did not express his shock, just as he had never told Vader how difficult it was for others to add spells.

It was a cold and humid October night. Professor Murray took out his wand and pointed it at the fireplace, and a ball of fire lit up the birches placed in the hearth.

The flames danced wildly, the wood made a crackling sound, and a faint fragrance filled the air.

Professor Murray looked at the wand in his hand, smiled, folded his hands on his abdomen, and stared at the dancing flames in a daze. His shadow was projected onto the opposite wall, like a giant.

It wasn't until Wade put down his pen that Professor Murray reached out to pick up the pieces of paper he had just written on, looked at them carefully for a while, and nodded slightly.

"Vade, your communication broad bean design is very innovative, but when it comes to alchemy, you should remember one thing -"

Wade raised his head and listened carefully.

“Being the best in one aspect is more meaningful than general perfection.”

Professor Murray said: "What you want to make is a communication tool. It is more convenient and simpler than the Book of Friends, but the most important thing is that it is stable and reliable and can exchange information across long distances. Otherwise, it is just a toy. That’s all.”

Vader nodded thoughtfully.

"And -" Professor Murray added: "Waterproof, moisture-proof, and defense, these three spells can actually be integrated into one. I once learned a spell when I was traveling in Egypt..."

Recently, when Wade was taking classes with Professor Murray, he always read a book on alchemy in advance, and then asked Professor Murray about the parts he didn't understand.

Ancient alchemists always gave all kinds of weird names to alchemy materials. The alchemy process was also accompanied by some obscure rituals, such as dancing and bathing in the moonlight before alchemy.

Professor Murray is very knowledgeable. He can always eliminate the redundant and erroneous parts and make the obscure knowledge easy to understand. Even if he just sits and chats for a while, Wade feels that he has benefited a lot.

In fact, such simple teaching has been absent for a long time.

"The last disappearing spell was used very well, but the spell can be modified like this -"

Professor Murray changed the positions of two magic words on Vader's magic array.

Wade asked doubtfully: "What effect does this have?"

"You can expand the scope of the disappearing spell... Vader, you just want to make the key parts inside the broad bean disappear to prevent others from cracking it. This is too gentle."

Professor Murray smiled and said: "How can it be enough to just make the broad beans disappear? After experiencing the first failure, the cracker will definitely find a way to lift the disappearing spell first - it is like a castle that only defends but does not attack, regardless of No matter how strong it is, it will be broken by the enemy sooner or later.”

"This modified part can make the burst of the disappearing spell more intense and unstable. So the guy who tries to crack it will have to pay the price with a part of his body."

"It could be a finger, it could be a whole person - I can't say for sure how much damage it can cause."

Wade looked at Professor Murray who spoke calmly and was speechless.

I always feel like the professor has revealed something terrible.

He paused and silently added the revised magic text to his design.

…

The end of October is the first Hogsmeade weekend at Hogwarts, and all third-year students have submitted their application forms.

So on the morning before Halloween, the students all got up early, had dinner, put on scarves and gloves, and went to Hogsmeade to play.

However, for the SSC group, Hogsmeade is not that attractive - they have been to this wizarding village many times before, and naturally they are not as excited as others at this time.

When Wade and Michael arrived at the auditorium, most of the students had already eaten and left, and the long table was in a mess.

Fortunately, the house elves in the kitchen had been paying attention to the students eating breakfast. When Wade sat down, he saw that the remaining baked potatoes on the plate in front of him disappeared and were replaced by a plate of sandwiches with a side of them. There is grilled sausage.

"I'm going to Honeydukes to buy some more candies. I heard there are some new items in the Spice and Joke Shop, and then I'm going to the Three Broomsticks for a couple of drinks - Vader, what are your plans?" Michael asked.

Wade picked up the sandwich and said, "I want to go to Remus' house first, and then I made an appointment with Marchionne."

"Oh... the one from Aslan's Magic Workshop..." Michael suddenly realized, and then said: "Then we'll split up then. When you're done, see you at the Three Broomsticks?"

"Okay." Wade nodded.

The two of them had breakfast and came to the school gate. Filch was checking the people who came in and out of the school with a list, to be wary of those lower-grade students taking the opportunity to sneak out.

Several girls were queuing up to pass through the gate. One of them saw Michael and Wade coming and suddenly raised her voice:

"To be honest, Parvati, there is nothing to look forward to at tonight's feast. Do you remember the dance at Sam's house last time? I thought it was great!"

"I remember that boy named Charlie invited you to dance!" Parvati giggled: "He was so nervous that he almost tripped over himself!"

"Yeah, don't you think he's cute?" Padma said, glancing at Michael behind her with the corner of her eye.

Wade looked to the side, and Michael looked straight at Filch, as if he didn't hear it at all.

"Pass."

Filch said with a gloomy expression, and Padma snorted and pulled her sister Parvati to the carriage next to them.

Several girls left in the same carriage, and some turned around and waved to them.

"What's going on between you and Padma?" Wade asked at this time.

Michael sighed: "Do you know Eric from the seventh grade? He published a paper in "Transfiguration Today" and was very happy. He held a small dance in the common room two days ago. Many people attended."

"Then what?"

"Lydia from the fourth grade invited me to dance--"
