Harry woke up early from bed.

The wind was blowing so hard that he was awakened. He glanced at the window, and it was pitch black outside.

Harry closed his eyes again, but felt a chill on the back of his neck, "Is it a leak in the window?" This thought turned a few times in his mind before he turned around and saw Pipi Ghost's annoying face.

"Why are you blowing like this?" Harry said angrily.

Pipi Ghost bulged his cheeks and blew hard twice again. Harry was so angry that he got up and sat up, and took out his wand from the pillow. Pipi Ghost then flew away like an angry ball.

The farce left Harry completely sleepy. He glanced at the others, who were still asleep. Harry opened the door and a ginger figure passed by his feet low, and he subconsciously caught it in his hand.

"Crook Mountain?" Harry looked at the cat in his hand. Its face looked like it had been slapped, and there was always an inexplicable ferocity. "Ron is right to be careful." He closed the door and threw it on the edge of the spiral stairs. "Go, don't make any mistakes. Hermione mixed with Ron a few times for you."

Crook Mountain glanced at him disdainfully, turned around and slipped away.

Harry was in a daze in the dim public lounge for a long time, and there were still a few hours before dawn, so he always had to find something to do. He found his essay on the duel system from his schoolbag and wondered how to finish it.

"——Follow the disarm curse as the core, well—at least, silently, without a staff, casting spells... concealment," Harry bit his pen, thought for a long time, and wrote: "Defense is also very important, and strive to practice the armor curse to the same level as the disarm curse."

After thinking about it, he crossed out the last sentence and changed it to "be able to use it proficiently and reach the level of the third level spell."

"As other spells as supplements, when facing long-distance enemies, use - use the imprisonment spell to get the first shot, so the silent spell is necessary." Harry once again dipped ink, "Concentrate the advantage spell to attack quickly - but if it is blocked, it means, what does it mean?"

Harry scratched his head and flipped over the notes next to him. This was the words of Professor Hepp, who was recorded in the summer special training. After turning a few pages, his eyes lit up and he quickly wrote, "—It means that the enemy is not a mediocre person. You must adjust your mindset and fight steadily. This reflects the advantage of mastering enough spells to find the enemy's weaknesses!"

Harry stopped and began to figure out what the sentence meant.

Professor Haypu said that his current level is far less than that of the senior Auror. Although his disarming curse is not much different in power, the gap in experience is very different.

He may confuse the enemy with a young face and let out a master, but if the opponent is prepared, the battle can be resolved in one or two minutes - he is the one who was solved.

Harry thought about it, what should he do if he encountered an enemy that he could not deal with, such as Sirius Black, or Snape?

After thinking for a long time, there was nothing we could do. If the disarming curse was useless, the coma, imprisonment, and freezing curse he mastered were even more impossible to be effective.

Thinking of this, he suddenly felt a little discouraged.

"Blake was a genius when he was in school. After graduation, he experienced war. His only weakness may be that he was imprisoned by Azkaban for twelve years and tortured by dementors so much that he was brainless..."

Harry heard from Hermione that Dementors are quite disgusting dark creatures. Anyone who approaches them will feel cold and rigid thinking. Then happiness is absorbed, and his emotions are depressed. Even the consciousness of resistance begins to weaken. Finally, it becomes a meal on the plate of the Dementors and his soul is sucked away.

He proved the credibility of Hermione's information with his own experience.

Harry shivered, and he remembered the name Hermione mentioned - the Dementor Kiss, "It's so evil."

It took two or three hours to finish Harry finally finished his paper by using the faint light in the lounge. "This is the most serious paper I have written so far." He said with emotion.

Harry packed up his things and looked at the sky. During the time he was writing his paper, the storm not only did not weaken, but became even more violent, but a faint light appeared in the sky.

He pinched the meal and walked towards the auditorium.

The auditorium was empty, and Harry was about to choose a middle position. His eyes passed outside and he saw a familiar figure.

It's Professor Haypu!

He was wearing a dark robe and was standing in the rainstorm. If it weren't for a flash of lightning, Harry wouldn't have seen it clearly.

"Does the professor have any worries? He wouldn't torture himself in order to experience extreme environments like Wood did?" Harry covered his hood over his head and walked out of the auditorium.

When he approached Professor Haipu, he was about to say hello, but he found that he had hit something and was led by a force to fall into the mud and water.

"Ouch! Pooh!"

Harry's mouth and glasses were splashed with mud, but he was curious now that he hadn't met the professor.

Felix looked down at him, "Harry, what are you doing?"

"Uh..." Harry got up from the ground and said hesitantly, "I saw you standing outside and wanted to say hello, but he didn't stand firm for a while."

Felix laughed, "It's not that you didn't stand firm... it's me. I'm just thinking about how to prevent rain and wind."

Harry was interested, "Is there any suitable spell?" He felt that he should use it.

"Waterproof and moisture-proof and inviolable from water and fire, the former has a better effect on isolating water and fog." Felix introduced that he looked at Harry's embarrassing appearance, took out his wand and pointed it on him with his backhand.

A large amount of water mist was steamed from Harry, and his whole body was warm. Then, he saw the water flowing down from his body and his clothes, as if he had a layer of oil on his body, and even half a drop of rain could not touch him.

Harry asked Felix for the two spells, and in fact, they were very similar and could even be regarded as a spell.

He pulled out his wand and knocked on his glasses, "Waterproof and moisture-proof!" The water flow automatically avoided the lenses, and his gaze became clear.

"The rain will never be an obstacle again!" Harry thanked Felix excitedly, feeling that he was more confident of winning today.

Felix said: "No need to thank me. It was Granger who asked me two days ago that there was a waterproof spell. I told her, but I might have encountered you in advance."

Harry was about to look back and thank Hermione for her, but a question arose in his mind: "Professor Hepp, have you mastered this spell? But you just said you were thinking about rain protection-" He paused for a moment and said uncertainly: "Windproof?"

"Yes," Felix said, "it can be expected that the wind will be very strong on Quidditch today."

"So have you come up with any solution?"

Felix smiled, "Didn't you just experience it?"

"Have you experienced it?" Harry tried his best to think about it, and his stomach began to roar, "Is it the Iron Armor Curse? I just hit the Iron Armor Curse?" He could only think of this.

"Yes," Felix glanced at him with approval. "The iron armor spell is invisible and intangible, but it can defend against attacks in both magic and physics. Although it is not powerful... but it is obviously windproof."

This sounds a bit incredible. Harry never thought that the Iron Armor Curse had such a purpose. Will normal people think of this?

"Harry, I said that when you are proficient enough with a spell, you can adjust the effect of the spell according to your own ideas." Felix said, a transparent spherical barrier suddenly expanded open with him as the center, almost sticking to the tip of Harry's nose.

Harry looked at the so-called "Iron Armor Curse" in surprise. He could even see the surface of the sphere emitted light, and the rain hit it, splashing out ripples.

He reached out and poked, the spherical barrier was slightly sunk, and immediately bounced his fingers away.

"So--you're successful now?" Harry asked. In his opinion, it was obvious that it was successful that the armor spell that had been transformed into a large colorless and transparent ball.

Felix tilted his head and signaled him to continue looking. The colorless and transparent spherical magic barrier began to sink toward the inside, closer and closer to him, and closer to a human form.

At the end, it was like he had a human-shaped air cover outside.
