"Potter, wake up! Potter..."

Harry slowly opened his eyes, the light of the torch was a little dazzling, making Professor Happ's shadow a little blurred.

For a moment, his expression was a little confused.

He got up from the ground and straightened his glasses, "What's wrong with me?"

"It's normal to get tired and lose strength." Felix looked at him, "Let's come here first today. Let's go up and eat something. I'll also make your special training plan."

Harry felt very uncomfortable, his limbs were weak and his whole body was fluttering.

He followed Felix staggeringly and climbed the stairs, his stomach tumbled.

It was not until he filled a large glass of juice and finished two pies that he felt that he had come back to life and was in the mood to think about some questions.

"Professor, you said this phenomenon is normal. Do you have a similar experience? Also, you told me that the period after the magic riot was very suitable for practicing magic spells, and this is your personal experience..."

Harry's speech slowed down, and he thought that Hermione had expressed sympathy for Professor Hepp very emotionally.

The background at that time was that the news of the duel club was released, and everyone discussed the topics around the word "duel". Professor Haypu's "glorious experience" was once again brought out to speak out, but the boys all wanted to replace him, while the little witches looked admiring or sympathized with his unfair treatment when he was in school.

And Hermione is one of them.

Harry couldn't understand her ideas at that time, but now, he suddenly understood a little.

Faced with his question, Felix said briefly: "It is indeed..."

What is it? Harry was still thinking about this question when he was lying in his own bed.

The next morning, Harry was woken up by Dobby's knock on the door. He opened the door in a daze. The elf respectfully handed over the toiletries, and Professor Happ stood next to him.

"Hurry up, Porter, we have a heavy task today."

Harry felt a novel experience, similar to his mood when he was a guest at the Burrow House and was woken up by Mrs. Weasley. Few adults intervened in his life to remind him to pay attention to the time of brushing his teeth - if it was not counted as the Dursleys roared at him.

All morning, they were huddled in the basement, and he kept casting the disarm curse, in the words of Professor Haypu, "We want to maximize our interests, and you will find that in the student stage, one trick will be eaten all over the world."

He felt like he was about to vomit, but Professor Heip kept pointing out his mistakes and spent a lot of time explaining the advanced skills of the mantra.

"You want to think of yourself as a duel, or a newcomer Auror. Your magic is very active, you can feel it, mobilize it, and control it, and let the magic come out in one go." Felix said, as he cast a super-sensory spell on Harry.

"At the same time, this is a good time to learn silent casting of the disarming spell."

"There is also the magic theory part. I will only explain what is most related to the disarming spell. It may not be of use to you in learning other spells, but we need to speed up the time. I want to see what level you will reach."

Harry found that when he was in the basement, Professor Hayp always seemed inhumane. He would wake up himself who was lying on the ground again and again without even delaying for a second. However, during the special training, he would take himself to the Florin cold drink shop, or stand with him outside the window of the Quidditch broom boutique store, staring at the latest samples of fire crossbows.

Of course, Harry guessed that Professor Happ had no broom in his mind, because once again, after two minutes of dazed, he asked himself when he used the disarm curse, "Does he feel a sense of pleasure? It's like you should have born to know this spell."

His answer was a bit sloppy at the time. He didn't remember whether it was "a bit similar" or "it was it" without any modesty.

They also met Neville Longbottom, his classmate, a round-faced boy who loved to forget things. He was with his grandmother, who looked scary, holding a big red handbag in one hand, and was scolding Neville sternly.

Harry wanted to escape because he had used Neville's name while riding the Knight bus, and he hoped Neville's grandmother would never find out.

But Neville saw Harry and waved at him excitedly: "Harry, Harry! It's great to meet you, I lost the list of books."

Harry hurriedly borrowed a piece of parchment from Professor Happ and wrote the name of the new textbook on it.

"Ah, you're Harry Potter, Neville mentioned you to me, a good kid, very talented. You guided him with his disarming spell, and he said you learned very quickly, unlike him..." Neville's grandmother held her handbag tightly and her eyebrows were twisted together, "This kid did not inherit the talent of his parents. I was worried until he received the notice,"

Neville looked at Harry with a bitter face and didn't dare to speak. The old woman was really scary, but what he didn't expect was that Professor Hepp, who was silent on the side, said: "Navi Longbottom, I saw you on the list of course selections. I'm very happy that you will choose my course."

"Are you a professor at Hogwarts?" Neville's grandmother asked.

"Felix Happ, I teach ancient magical writings, my wife."

"I have heard of your name, Mr. Hepp, I admire your courage very much. Not everyone dares to face a despicable pure blood family," she pointed proudly at Neville, "just like his parents, in the war years, they have always stood on the front line of resistance to Voldemort's rule, even if they were tortured by some scum..."

She wiped the corners of her eyes and left with Neville.

Neville spoke to Harry: See you on the train. Then he was dragged away.

"What's wrong with Neville's parents?" Harry asked, looking at his back.

Felix replied: "I don't know very well, I must have died in the battle with the Death Eaters."

...

In a blink of an eye, Professor Haypu showed him a thick stack of forms.

"All these are the data for me to practice the disarming spell?" Harry said in surprise, pointing at the thick parchment.

"There is no need to make a fuss, tell you a secret. I'm doing well in the Muggle world, and that's all!" Felix joked.

Harry looked at the curve above, and his progress was not obvious in ten casts as a unit, but if he was in hundreds of casts as a unit, his progress speed was a bit incredible.

"It's interesting, isn't it? No one has ever studied this." Felix said in a brisk tone.

"Professor Happ, has my disarm curse reached level 4?" Harry looked at the annotations on the parchment and couldn't help but widen his eyes. It seemed that the Aurors had been working for a few years.

"Ah, do you remember its division?" Felix said. "To some extent, it does meet this requirement. You can flexibly control the power of the disarming spell and make more detailed operations, such as drawing an arc, silent casting, etc...."

Harry was so happy that he ate ten strawberry ice cream in a row, and there was a refreshing pleasure from head to toe. But Professor Happ quickly poured a bucket of cold water-

"There is only this spell, Potter, if you want to go deeper in the duel field, you should consider establishing your own fighting style at the right time."

“Fighting style?”

"For example, which kind of spell is used as the core-"

"Disarming curse!" Harry said without hesitation.

"...Don't make a decision easily. In addition, there are supporting spell systems, such as: what spells do you use to defend, what spells do attack, which spells are used to restrain opponents, and which ones are used to deal with difficult problems. You must think clearly about these."

"Not to mention the pace of the battle, on-site judgment, plan rehearsal, etc."

"Of course, there is also targeted knowledge. Well, maybe I have too high requirements for you, which has surpassed the average Auror."

Harry excitedly wrote down the notebook: "It's okay, you can speak as comprehensively as possible." He had a sudden inspiration and imitated Hermione's tone and said, "Professor, I actually want to write a related paper!"

“… Very good, I will watch it.”

In the days before school started, Professor Happ did not allow him to continue to release the disarming spell—which gave him a sigh of relief, and he finally came into contact with the second spell.

"Potter--"

"Professor, you can call me Harry." Harry said with some trepidation. He practiced several times in the morning just to say this.

After a moment of silence on the other side, just as he was a little upset about his recklessness, Felix said: "Okay, Harry, I'll call you that privately."

"It's hard for your disarming spell to make progress in a short period of time. Even if I have all the help of you, it won't be possible-"

"Professor, I'm very satisfied." Harry said contentedly. He had changed drastically. At least he thought it was not a problem to beat Malfoy and his two followers.

He saw Professor Heip smile at him, "I also got the test data I wanted, and your magical activity is gradually returning to normal. I have tried my best to extend this process, but unfortunately, I can't violate objective laws."

"In the next day or two, we will suddenly learn some spells, and the effect will be three to five times faster than you usually do."
