Professor of Pharmacy at Hogwarts

Alexis sent Hermione and Ron away and called Harry over.

Harry walked into Alexis' office, looking very uneasy.The relationship he had cultivated over the past few months seemed to have suddenly disappeared, and Harry turned into a little boy huddled in the cupboard again.

He lowered his head slightly, peeking at Alexis's expression from above the frame of his glasses, holding a corner of his robe nervously with his fingers, and stood across the table without saying a word.

His whole person exudes the aura of "I'm a doormat, come and bully me", like a frightened little sheep.

Alexis looked at the face that was similar to her friend's and the green eyes, which shone with fear and bewilderment.

This made him angry and funny.

"Harry, sit down, sit down and talk."

Alexis pointed to the chair and softened her tone.

This is not okay, how can you be so weak when you are standing in James' face.

"I heard that because I had something to do at Christmas, you were very upset to cancel our agreement——"

As soon as Alexis said this, Harry jumped up from his chair like a frightened rabbit.

"Easy, Harry, don't be nervous-"

Alexis quickly waved her hand, telling him to relax.

"I don't mean to blame you." Alexis tried to slow down her tone. "I just wanted to talk to you. Now I have a new idea."

"Would you like to come with me?"

"Where to go?"

"Azkaban."

Harry, who had just sat down, stood up again, and now Alexis had to stand up as well.

"Don't react so much."

Alexis explains

"We got news that someone is going to attack Azkaban on Christmas night. Most people don't know about this yet. I'm going to stop the enemy. Do you want to go with me?"

Harry's eyes widened and he looked at Alexis in disbelief. At this time, all other messages in his mind disappeared, leaving only "Azkaban", "Azkaban" and "I'm going to Azkaban". class"……

"Hey!"

Alexis waved her palm in front of Harry's face, wondering if the boy had been shocked by the news.

"Is it really possible?"

Harry asked.

The uneasiness in his eyes dissipated in an instant, replaced by excitement and anticipation.

"But, I - I've just been exposed to - I mean, I haven't learned enough spells in Defense Against the Dark Arts class, and I'm afraid I'll be a drag on you."

After the excitement, Harry said worriedly.

"It doesn't matter." Alexis said with a smile. "I think if I really need your help by then, even if you have passed NEWTS, it will not help."

"Harry, there are risks for you when I propose this choice." Alexis said slowly, seeing that Harry had already digested the news.

"You may not be able to do anything to help. If too many people come, I may not even have time to take care of you."

"But at least we can spend Christmas together."

"It's just that maybe the food for Christmas dinner isn't that good."

Harry nodded vigorously and mustered up the courage to look Alexis in the eye.

Well, the familiar Mr. Harry Potter is back.

"That's fine with me, Mr. Alexis."

"I'll try not to cause you any trouble."

Alexis nodded with satisfaction and told Harry some more precautions. Harry took note of them all carefully. Finally, Alexis took a deep breath and said solemnly

"There's one last thing left."

"Harry, when we go to Azkaban, we will not only face possible enemies, but also the guards of Azkaban -"

"Dementors."

"Dementors?"

"That's right." Alexis frowned slightly. He couldn't think of any good explanation for "creatures" like dementors, so he could only say

"That's a unique kind of creature - let's call them creatures. They suck people's happiness. In order to deal with them, you have to learn a spell."

"Call God to guard."

"Unfortunately, Harry, I need to find someone else to teach you this spell."

"Why?" Harry looked confused. "You can teach me, if you have time."

If I could, I would have taught you a long time ago, but I have been trying for more than twenty years and I can't learn this curse! ! !

Thinking of this, Alexis became a little angry. Why couldn't he do a spell that Lily could do, James could do, Black could do, Lupine could do, and even Snape could do it? ? ? ! ! !

Alexis shook his arm and coughed dryly, "Let's go find Lupine. Lupine is your Defense Against the Dark Arts teacher. He should be responsible for this."

He simply didn't answer Harry's question.

After saying that, Alexis put on her windbreaker and hurried out the door without giving Harry time to continue asking questions.

Harry fell behind, looking at Alexis's back with a trace of doubt in his eyes.

Why did he feel like Alexis was running away?

……

Alexis made a good calculation and passed on the task of teaching Harry to call the God Guard to Lupine, and asked Lupine to be responsible for teaching Harry within a week or two.

The curse of Calling God Guard is different from other spells. It has unique requirements for the user. Alexis remembered that Dumbledore said when teaching him that he should think of something happy when using it. "Heart toward the light" or something like that.

Invoking the God Guard requires that after chanting the spell, in addition to the standard hand gestures, the caster also needs to focus on recalling a particularly pleasant moment for a year, and use the most positive emotions to summon a embodied magical creature.

It may also be non-embodied.

According to Dumbledore, "This spell is very simple, Alex, and I'm sure you'll learn it in no time - perhaps in just an afternoon -"

Then thousands of afternoons passed, and he still didn't learn...

No matter how Dumbledore taught him or how he described it, Alexis just couldn't do it. He desperately thought about the sea breeze in Nurmengard, the pumpkin patch, and the horror set props and toys made by Grindelwald. , thinking about stealing wine with James and the others, and then shouted

"Call God to Guard"

Then, nothing happened.

Dumbledore only had to wave his wand lightly and say "Calling the Guardians" slowly and slowly, and a translucent phoenix emerged from the top of his wand and circled around them.

Looking at Alexis's flushed face, I have to say, this thing is very frustrating.

In Alexis's career of learning magic spells, it only took him a short time to master almost all the magic spells. Some of them even only needed to be read once before he could use them calmly. Only two magic spells made him master it. He suffered a lot——

One is the God-calling Guardian, and the other is the Animagus transformation.
