"First, the first thing... Sarah, if I say I want to try to establish contact with bill through alchemy next, do you have any feasible way?"

On this issue, Hermione wanted to ask Sarah about it, which she had mentioned before when discussing with Neville and them.

In view of the fundamental difference between alchemy and conventional magic, if we only use the former to try to establish long-distance communication, we may be able to build a secret communication mode that can't be found by corpses, demons and halbo.

Yes, at least Hermione seems to think so.

However, after hearing her thoughts and expectations, Sarah soon shook her head.

"Making an alchemical prop that can maintain long-distance communication and even mutual dialogue should be a big problem. But if I have to hide it from halbo, I can't guarantee it... Hermione, I think you may have some misunderstandings about alchemy."

Hermione was stunned when she heard the speech.

"Well, what misunderstanding?"

"That is to say," Sarah said with a gesture of her hands, "Although there are great differences between alchemy and conventional magic in the system, and even the research on the approach to the essence of 'the way to use magic' is completely different. In the final analysis, they actually come to the same goal by different ways - for example, 'rules'. In alchemy, their name is' material soul'."

"Material... Soul?" Hermione repeated the phrase, which could be seen, and her expression was full of doubt.

"That's right!" Sarah nodded. "Of course, the 'soul' in alchemy is not the same as the 'soul' in conventional magic. In ancient times, some alchemists also called it 'Reiki'. In fact, you can roughly interpret this name as... 'form of matter'."

At this point, she simply waved her hand and said:

"In a word, I hope you can understand that the difference between alchemy and magic is not as big as it was at the beginning. Remember what I mentioned before? Mr. McLean helped me solve the great hidden danger in me by using his achievements in the study of soul rules. And you already know... I'm one The product of total alchemy. "

"So," Sarah said last, "Let's not talk about the devil. At least halbo is undoubtedly a powerful wizard who has an extremely in-depth study of magic. If I use Alchemy to establish a stable long-distance communication channel, such a big move may not be long before halbo finds out. Once he intercepts it halfway... How dangerous will such information leakage bring us, You should know better than I do. "

With these words, Hermione couldn't help falling into a deep thought for a while.

However, in fact, as long as we want to understand the root of the problem of long-distance communication, it is the most clear thing. The most fundamental problem is the gap of strength.

Whether it's conventional magic or alchemy, Hermione always feels tied up. In the final analysis, it's because Haier Bo is still too powerful for them.

Even now, everyone has grown up a lot, but at most, they have just stepped into the threshold of regular magic.

Even if Harry and Safina can barely use the branch runes of the soul rule to fight, I'm afraid they will only be like clumsy children holding heavy swords trying to cut. It's good not to hurt themselves!

Not to mention the more detail oriented research application such as "magic communication", if it is forced to do so, it may end up harming itself.

Having figured this out, Hermione finally had to look down a little depressed.

"I see... So now it seems that one-time information transmission through the patron saint curse may really be the safest and most effective way of communication we can do at present."

"Yes!" Sarah nodded slightly. "It's said that Professor Dumbledore invented this method? Well, it's really admirable."

"Who said no?"

Hermione sighed. To tell the truth, she missed the great old headmaster again. But before long, she waved her hand again and said:

"Forget it, let's pretend I haven't asked this question! In fact, I have another question. I need you to think about it for me."

As she was saying this, she gave a little meal, and then suddenly turned her head:

"There's something I have to tell you first. In fact, just now, Delphi has left - she said she was going to London."

"Really?"

Sarah didn't seem to be surprised at the news. After thinking about it, she raised her eyebrows slightly and asked:

"Mr. McLean has gone to London? Is that accurate?"

"Well... I can only say, I don't know."

Hermione was surprised to see that Sarah was calm, but she didn't tangle more about it. After all, the focus of the problem was not Sarah's reaction.

"Before Delphi left, I talked to her a few times. And she seems to think that it is likely that Maka's emergence... Or more likely, another battle between Maka and halbo took place in London that led the three demons to London one after another?"

"I really can't deny this possibility," Sarah said with a blink.

"Yes!" said Hermione, "But isn't it more likely that halber will be the one who shows up in London? Delphi is undoubtedly a very clever witch, which I don't think she won't understand. Therefore, if she has to give a reason for her strange persistence, it may be that... She doesn't want to let go of any possibility of finding Maka."

After a while, Hermione and Sarah both stopped talking temporarily. They seemed to be thinking about something. After a while, it was obvious that the latter finally spoke again.

"Maybe there's another reason," Sarah whispered. "I think she may have found other clues about Mr. McLean in London. It's just that for some unknown reason, she doesn't want to tell you."

As soon as Sarah finished, Hermione was stunned and a picture flashed in her mind - she remembered that there seemed to be a short but somewhat strange pause when she talked with Delphi.

After that, Delphi directly interrupted the discussion on whether Marca would be in London.
