"Where are you, Professor McGonagall?"

Seeing that he had been discovered, Professor McGonagall stopped hiding.

I saw the black cat with sharp eyes emerging from the shadow under the bookcase. The black cat's hiding method just now is somewhat similar to Xingke's method of operating shadows. After all, the technique comes from the same source.

If the black cat hadn't had the urge to rush up and stop Xingke when he sent the three teenagers away, Xingke would have almost ignored her.

"Hey! Long time no see, Professor McGonagall."

Xingke raised his hand and waved, taking it as a greeting.

"Long time no see, ma'am."

But Illya held up her skirt and bent down in a decent manner, looking more like a noble than Xingke.

As the black cat moved forward, it was wrapped in a black shadow and transformed into an elderly lady wearing a green robe.

Her expression first lingered on Illya's face for a moment, then she took a serious look at Xingke's face, frowned, and wanted to say something, but finally decided to say hello first:

"Long time no see, Ms. Einzbern, welcome back, and... this one, is you and Professor Cavendish's... daughter?"

"At least you must misunderstand me as your son!~"

"Ah, is it a boy? Sherlock would be happy if he heard the news. He thought the Cavendish family was going to end in his hands."

As he spoke, Professor McGonagall used her wand to adjust her glasses, looked down at the stars with a majestic gaze:

"However, whether you are a lady or a gentleman, you must at least understand the correct greeting etiquette when meeting your elders. Don't look like your father."

"Uh... I'm sorry, ma'am, but let's sit down and explain slowly! I have some tea here that I brought back from another world, right?"

I don’t know why, but I always feel a little guilty in front of Professor McGonagall. No wonder Illya has been an obedient lady from the beginning. She has long expected Professor McGonagall’s [Aura of a Disciplined Teacher]!~

After regrouping, Professor McGonagall went out to inform the professors who were waiting outside. During the disbandment, Xingke and Illya tidied up the office and heated up tea.

"So it turns out that after just over twenty years, the magic power of the access control circle has deteriorated by more than one level. It was really inconvenient to have no gem magic to renew the magic."

Xingke checked the magic on the door and discovered the problem.

"Is that why you let those three naughty children sneak in? Jis, you had your days when you were young."

Illya placed three sets of tea sets on the coffee table.

"Everyone has their youth, but I know that Professor McGonagall was a beautiful lady when she was young, right?"

"Don't think that you can gain anything by promoting me...Professor Cavendish."

Professor McGonagall pushed open the door and heard Xing Ke flattering her.

"The advantage is that it can prove that I am the real Gisforgo Cavendish! Don't you already believe it?"

"Yeah, it's true..."

Professor McGonagall kept the photos and portraits of her youth very well, but when Xingqi went to the old house, he rummaged through them... That was her negligence.

"Then you just said that your name is [Little Gisfalgo Einzbern Cavendish]..."

"Of course I'm using those children to make a little joke with their parents. It will be very interesting."

Although this is not 100% a joke, Xingke's current body is indeed the product of the fusion of his and Illya's bloodlines.

"Okay, these details are not important anymore. I just couldn't accept that you changed your body for a moment..." Professor McGonagall raised the cup, her eyes lit up when she smelled the aroma of tea in the cup, and she took a sip: "

There are many magic and rituals for changing bodies, but most of them are not perfect and have strong side effects. The soul will be corroded and the lifespan will not be increased, just like..."

"Like Black Tom?"

"...Yes, although you are very willful, you are also a kind and good boy at heart." Professor McGonagall put down the tea cup, looked at the stars seriously, and said slowly: "I was worried that you would accidentally enter [Eternal Life].

The wrong path."

"..."

Xing was stunned for a moment and wanted to laugh, but couldn't.

In other words, it would be really rude if Xingke still looked playful and smiling in this situation.

"Don't worry, Professor McGonagall. I'm keeping an eye on him so that he won't go astray!"

At this time, Illya smiled and helped Xingke out of trouble:

"Moreover, he didn't do anything outrageous like taking away his own descendants, right?"

Illya still knows what Professor McGonagall is worried about. The current image of Xingji is a combination of [Gith] and [Illya] when they were children. Anyone who is familiar with the two people can see it.

come out.

"Einzbern in Germany, what is the most famous magic inheritance? You should have heard about it, right?"

"...[Homunculus]? Shouldn't that thing have been classified as a [taboo] by the Christian Church three hundred years ago, and was abandoned to the point where only dolls can be made?"

"Maybe that's the case? I don't know for sure. Our family has severed ties with the main family since my mother's generation. But, Professor McGonagall, what if it's magic from another world?"

"Magic is more prosperous and there is no timeline for its decline? If it is Cavendish's magical power, maybe it can..."

Professor McGonagall frowned and made an acceptable answer within the scope of her own understanding. The time converter will split the world line, and she was considered an expert in this area of ​​research in her early years:

"In other words, you two have been missing for more than 20 years and have been in other worlds, so everything makes sense."

It seemed that Irija didn't need any explanation, Professor McGonagall gave herself a reasonable answer.

"Well, although it's not completely correct, the principles are similar." Ilia thought for a while and decided to give up the detailed explanation.

Xingke also drank tea and nodded.

They understood that Professor McGonagall did not actually think that her conjecture was completely correct in her heart, and that it was even possible that it was completely different. However, she still did not ask Xingke and the others.

Because she knew that her relationship with Xingke and Ilia was just that of a former teacher and student. It was very disrespectful to inquire too much about other people's secrets, especially the secrets of magicians.

"Since Professor Cavendish's physical problems are beyond my cognitive scope, it would be arrogant of me to use my values ​​to evaluate and interfere in this matter."

"Where can I get inspiration and a way to travel through the world? It's because you lent me those research materials in the first place."

This is a fact without any exaggeration, it is the reason for everything.

"Oh? If that's the case, that's really a happy thing." Professor McGonagall's wrinkled mouth couldn't help but curve.

The magic materials that were abandoned and gathering dust in the attic due to the changes of the times can be carried forward by his own students, and go further... Just knowing this makes Professor McGonagall very happy.

As a professor or a principal, can there be anything more gratifying than being grateful to my students many years after they graduate?

Then, Professor McGonagall took a sip of tea, relaxed and sighed:

"But, as expected, in the study of time and space magic, the amount of magic power is a critical issue...
