A wisp of silver gas, spewing out from the end of Albert's wand, formed a silver ball of light in the void, reflecting the pale faces of the people in the dimly lit room.

With a creak, the door opened, and the red-haired girl pushed the door and walked in, her eyes falling on the ball of light floating in the air, and she said gently, "I found that the private library couldn't enter, so I guessed that you were probably practicing magic." By the way, was that the Patronus just now?"

"Hmm. Albert dispersed the Patronus, closed his eyes, and the walls of the room immediately lit up.

"It's said to be a hard magic to master. Isobel sat down in a chair next to him, looked at Albert with a smile and asked, "How are you learning?" ”

"Preliminary mastery. Albert walked across from Isobel, looked at the girl in front of him and asked, "What is your Patronus?"

"How do you know I have mastered the Patronus Charm?" Isobel took out his wand, waved it, conjured two teacups out of thin air, and then poured the milk tea from the thermos into the cups, pushing one of them to Albert.

"Guess!"

Albert took out a box from his leather pouch containing sweets bought by Duke Honey, and he looked up at Isobel's face with a shallow smile, "With your abilities and talents, it shouldn't be difficult to learn the Patronus Charm. ”

"It's Snow Fox. Isobel said. "What about yours?"

"The Sphinx. Albert said helplessly.

"I think this Patronus is a good fit for you, why don't you seem to be satisfied?" asked Isobel as she took a sip of milk tea.

Albert briefly addressed the Animagus concerns.

"There is indeed such a saying. However, when the Animagus is transformed, as long as someone is watching, it is basically not prone to problems. "Isobel admires Albert's ability, he is only in the third grade, and he has already begun to fight the idea of Animagus.

"Actually, I think Snow Fox is quite suitable for me. Albert looked Isobel in the eye and said, "At least, there's no trouble with that." ”

Isobel was just smiling and seemed to be happy.

"Professor McGonagall promised to help me, though. At the moment, I still don't have a clue about the Animagus. Albert thought for a moment and said, "This...... There's no rush yet, I'm ready to complete the transformation of Animagus before I graduate, and if I take the first step, I'm sure I'll succeed. ”

"I like your confidence, it's really fascinating. Isobel held his chin in one hand and cut some pastry with a fork in the other and put it in his mouth, "By the way, what were you trying just now?"

"Try the advanced use of the Patronus Charm. Albert thought for a moment and said, "Try to hide the Patronus's form, or...... As far as I know, Headmaster Dumbledore has created an advanced use of Patronus that can be used to transmit messages. ”

What were you trying to do with that?" Isobel became a little interested, "Tell me how it works!"

Albert gave Isobel the information he had obtained from Aberforth and the information he had gathered, as well as a diary he had kept during his training.

Seeing a notebook on how to practice the High Patronus Charm, Isobel suddenly understood where Albert's genius name came from.

It's not just talent, it's hard work!

She took five minutes to read the notes given by Albert, closed her eyes, thought about it carefully, and said: "I think it may not be as difficult as you think, you will fail, it is very likely that you were misled at the beginning, or that the younger brother of Headmaster Dumbledore did not understand the essence at all, what he taught you was only his understanding, and his thinking and yours are obviously two completely different things, which is also the reason why you went in the wrong direction at the beginning." ”

"Was it wrong in the first place?"

Albert raised an eyebrow, but patiently listened to Isobel continue.

"Yes, it's too hard to do two things. Isobel told Albert about his idea: "You can summon a Patronus, implant what you want to say into the Patronus, and then let the Patronus deliver the message." ”

"Divine Guard!"

Albert immediately made an attempt, concentrating on the "hello" into the Patronus, and with a slight wave, the Patronus landed on the table in front of the two, sending out Albert's version of "Hello".

It really worked!

Albert was shocked, so what did the old man of Aberforth teach him?

To this day, Albert still can't make his brain repeat what he wants to send in the process of accumulating energy?

"Perhaps, I should write him a letter, and if it really doesn't work, ask Professor McGonagall. Albert tapped his finger on his forehead, how could he have forgotten Professor McGonagall?

That one seems to be a member of the Order of the Phoenix, and should also use a high-level Patronus charm.

Even if Professor McGonagall doesn't want to teach, isn't there still Professor Flitwick?

Hum!

If Aberforth dared to fool himself with some fakes, Albert admitted it, he really didn't think about it at first, but he didn't mind making some trouble for the other party.

Taking his money for nothing, it will be very hot.

"It seems that you have succeeded. Isobel was also surprised, she just said her opinion, but she didn't expect Albert to succeed all at once.

"What a genius you are, dear Isobel, you know, I've been bothered about this for a long time. Albert happily stepped forward and gave each other a hug, and looking at her face, Albert leaned over and kissed her.

A few long minutes...... It could also be half an hour...... Or a few days, the two separated.

Albert's originally slightly accelerated heartbeat gradually calmed down, and he looked at Isobel and grinned,

"Sorry, I couldn't hold back. ”

Actually, Albert wanted to do this for a long time. The two are alone like this, or it is not the first time that they have dated.

This time, it's more like going with the flow.

"Are we officially dating?" asked Isobel, his index finger caressing his lips.

"I thought we had been dating for a long time. ”

"That's right. ”

The two looked at each other and smiled.

"By the way, thank you for your birthday present, this is for you. Albert took out a two-way mirror from his leather pouch and handed it to Isobel, "I was going to wait for your birthday." However, I would like to give you your birthday present in advance!"

"You succeeded?"

Isobel asked curiously as he took the brand-new two-way mirror. She knew that Albert was working on a two-way mirror, but she was surprised that the other party would make it so quickly.

"No, it's a finished product for me. Albert pulled another box out of his leather bag, "For now, I can only make this thing." ”

As he spoke, he opened the box, took out a silver metal card slightly larger than the wizard card and handed it to Isobel, with a relief of the Sphin's Harpy on it, and a line of words: Do not disturb the dragon's sleep.

"All you have to do is change the text on the back of the bookmark and it will show up on my side. Albert explained the use of newsletter bookmarks.

"Looks like you're working well on your advanced change spell, is this the prototype for the communication blueprint you came up with?" Isobel wiped the text from it with his wand, making the phrase appear on the back of the bookmark.

"Yes!" Albert said helplessly, "Unfortunately, I found that it is far less practical than I thought, and there is still a long way to go if it is to become popular." ”

Wizards can apparition, and can be contacted through the fireplace if necessary. However, Albert felt that after a few years of chaos in the wizarding world, this kind of thing should be popular.

"This thing, although not as practical as a double-way mirror, will love it for students in love. Isobel smiled and said, "I promise." ”

"I trust your judgment, actually, I think so. Albert laughs, "Of course, it feels better to go on a secret date together." ”
