The next day, in the classroom with the sign "Front Lookout Club", Harry, Ron and Hermione placed cushions and wooden targets on the floor in order. These things might be used later.

The door was pushed open, and Fred and Weasley walked in swaggeringly, "Why are you here today?"

"Professor Happ is coming." Harry said.

The twins became interested and looked at Harry. Harry shrugged, "He probably wants to see my Patronus and guide us by the way."

"Cool!" said Fred.

They also joined in. When Ginny and Luna came in, there were already many people in the classroom. Ron and Neville were moving a large wooden box together. The box was full of various spell books and training props.

"I'll help." Ravenclaw student Anthony Goldstein shouted, he raised his wand and pointed at the wooden box. "Don't!" Neville was startled and shouted quickly, but the spell had already been recited, "Wingardium Leviosa!" The

wooden box swung violently, knocking Ron's hand away, and a corner of the box hit his foot, making him scream in pain. Then the wooden box slowly floated up, swaying left and right as if drunk, and rising higher and higher, soon hitting the ceiling more than ten feet high.

"You have to learn to control it." Harry ran over, looked up for a few seconds and said.

"Sorry! This is the first time I control such a big thing." Anthony said

with a sad face. "It doesn't matter the size," Harry shouted into his ear, "You have to learn to control your spell."

"Spell?" Anthony said confusedly.

"Yes, you have done it very well now, look! You successfully made the wooden box fly to the ceiling, now I need you to complete the next step and let it fall again." Harry said, the people around looked at him anxiously, and Hermione muttered something.

"What are you doing?" Ron asked, standing on one foot, and Neville supported him beside him.

"Prepare the shock absorption spell, just in case." Hermione said quickly, "Oh, but it seems that it won't be used."

The big wooden box fell back to the ground little by little, and Anthony collapsed on the ground, his face covered with sweat and panting. Harry pulled him up, "Well done." "Thank you." Anthony muttered, and the members around him applauded.

A voice appeared at the door. "Very wonderful teaching. If it was in class, I would consider giving you 20 extra points." Felix said with a smile.

The members of the front-line observation station gathered around. "Professor, what are you going to teach us?" Fred said.

"Why not talk about the ancient magic hidden behind the twelve amulets?" Lee Jordan suggested. "The last demonstration was too short."

Felix wanted to lock his memory in a small dark room, but now he could only follow the memory's prank and said: "Last time was equivalent to an introduction to mobilize your curiosity-I hope to give students more time to study on their own... As for teaching, it might be a suspense and put it at the end of the school year, just like the illumination. I just came here to take a look today. Potter, I am very interested in your mutant Patronus."

"Oh, okay." Harry said.

This was agreed upon long ago. The professor said that he would take time to come after the Christmas holiday, but he didn't expect it to be delayed until now. Harry brewed his emotions, "Expecto Patronus!" He whispered, and the silver stag ran out of his wand and circled around them.

Harry was very good at this magic. He saw Professor Happ nodded slightly, which made him excited. While he maintained the Patronus Charm, he stretched out his other hand. It was as if an invisible carving knife appeared in the air, outlining a bright magic pattern.

In the blink of an eye, the magic symbol turned into a ball of purple mist, with a faint golden light.

Harry raised his head and the silver stag hanging in the air kicked its hooves and ran towards him. He did not hide, but stretched out his hand. To others, it seemed that he was ready to touch the horns of the Patronus. Then - the purple mist and the Patronus merged, like ink dripping into a pool of clear water. The vague outline of the Patronus became clear, and its hooves fell to the ground, making a "clacking" sound.

Felix was amazed.

"Have you tested its power?" he asked.

Harry scratched his head in confusion. There were no Dementors at the moment. When he saw Professor Happ looking at the wooden target, he instantly understood. "Go ahead," Harry said. The stag nudged his hand with its huge horns, then turned and charged at the wooden target. "Bang!" The wooden target was knocked over.

The horns of the Patronus, which glowed purple, dimmed and seemed to have turned into a blurry light. Harry tried to control the spell, and the stag's body became stable again.

"Professor, it has another form," Harry said. He pointed his wand at the stag, and the purple mist on the Patronus faded. Then the stag's body expanded rapidly, two or three times taller than before. "Well, it just got bigger, but I don't know what it's for." He said embarrassedly.

"It will always be useful," Felix said, "Have you tried other runes?"

"I tried 'Calm' and 'Enthusiasm', but the effect was not very good. It conflicted with the Patronus Charm." Harry said honestly.

"Strange." Felix was a little surprised. "I tried it myself and there was no problem."

"Professor, have you tried it too? And it worked?" Harry couldn't help asking.

"Yes," Felix opened his hands, and a silver swift emerged from the air and landed on his shoulder. He pinched out two magic runes and handed them to the swift's mouth. It opened its mouth and swallowed one of the cyan symbols. The silver light gradually turned light cyan.

A faint halo spread out, and the people around immediately felt very calm and peaceful. They were lazy, but their consciousness was very clear. Then the swift patronus swallowed another fiery red magic rune. Its body seemed to be covered with a thin layer of flames. It cried loudly, and a halo spread out.

The calm mood was immediately broken. Fred and George, who were close, clenched their fists and looked excited. "Fred, I have a good idea. How about getting Peeves to join our club?" George said excitedly.

"I can't wait!" Fred responded enthusiastically, and the two of them took steps to walk out.

Harry also felt something was wrong. His passion for Quidditch was back. He just wanted to ride his broom in the sky. Maybe taking Ginny with him would be a good choice? He had crazy thoughts in his mind, and then the brain block technique started to work spontaneously. His mind felt cool. He subconsciously grabbed the twins who had the biggest reaction.

"Professor?" he shouted anxiously.

"I know."

Felix canceled the magic and looked around. Most people seemed to have been hit on the head and gradually came to their senses, but their expressions were still confused.

"Sorry, I didn't expect such a big reaction. You guys continue to practice. Don't worry about me. I'll study it myself." Felix sat on the big box in the corner, secretly wondering what was going on.

Harry shook his head, his brain blocking out the adverse reactions. He looked at the others, who were obviously in a state of vain enthusiasm and confusion.

He clapped his hands to attract everyone's attention. Harry said with a stiff face: "Today we continue to practice the Patronus Charm. I know it's been a long time, and you may be a little rusty-"

"Nonsense! I'm in great shape now!" Ernie Macmillan said loudly.

Before Harry could continue, Ernie began to wave his wand, his expression focused and fanatical. Harry suddenly realized that these people were not affected by the "Enthusiasm" rune? Using the power of the Patronus to amplify emotions... But how did the professor do it?

The effect of today's training was surprisingly good.

It took Ernie only half an hour to condense a vague shape. Harry was shocked when he saw it. Why did Ernie's Patronus feel like his cousin Dudley? He stared at it for a long time before he recognized that it was a boar, and for this reason he almost missed the wonderful performance of the Weasley brothers-they gathered the vague silver mist together to form a vivid magpie.

"Look, Harry!" Fred shouted, but when he changed the direction of his wand, the magpie turned into mist again.

"You are very close, try a few more times!" Although Harry didn't know what was going on, he encouraged.

"Got it, got it." Fred said impatiently, and continued to study the weird magpie Patronus with George.

Fred's attitude was not an exception, Harry found that most members became more focused, but also hated to be disturbed, as if immersed in their own world. This may be the influence of the professor's magic, Harry thought.

He approached Felix in a sullen manner. The professor held a swift in his hand and kept feeding it with magic runes of various shapes. The swift was dyed colorfully.

"What's wrong?" Felix asked with his eyes closed.

He was experiencing the structure of the swift's Patronus - his Patronus was much more stable than others, even beyond the definition of the 'Patronus Charm' itself, because he inherited the memory nodes of Ms. Rowena Ravenclaw and used these nodes to almost reconstruct his own Patronus.

"At least they don't need my guidance today." Harry said.

"Oh, I'm so sorry, I seem to have messed up your activities today." Felix said.

"It looks like they have gained a lot," Harry shook his head, then looked at the others in the classroom with some concern, "Will there be any sequelae?"

"No, it's like a sudden rain, the impact is minimal. But they should feel tired, you can prepare some chocolate in advance-"

Harry nodded.

"Unless they are in this mood for a long time, then-" Felix stopped and opened his eyes.

"Professor?" Harry looked at him strangely.

"I have been thinking about what to use as a carrier of emotions." Felix murmured.

"Now?"

"It seems that I have found it... The answer is at hand, isn't it?" Felix lowered his head and examined his Patronus. "Say sorry to me and them... Also, the reason why you can't integrate other runes into the Patronus has been found, because it is not a magic at all. I will write it down and give it to you when I have time. It's a bit troublesome and I can't explain it at the moment..." He jumped up, using the Room of Requirement as a transfer, and disappeared in an instant.

Harry was stunned. He stretched out his hand and poked the air in front of him. There was someone sitting here just now, but now it was as if the professor had never been here. Harry sat in Felix's seat and was suspicious for a while, but naturally he didn't get anything. He looked up at the others. They didn't seem to notice it, except for Hermione who cast a puzzled glance, but she turned her head to continue practicing the Patronus Charm.

Except for Harry, it seemed that only one person was not affected at all - Mafalda came over and asked curiously: "What did you talk about? And why did Professor Hep suddenly disappear? Isn't it impossible to Apparate in the castle?"

"Nothing," Harry said vigilantly: "You are not affected?"

"Yes, I really want to interview you now, really want." Mafalda used two "especially" in a row.

"Uh..." Harry was speechless. After a while, he whispered: "It just so happens that I have something to ask of you."

"Advertisement? Or exclusive revelation?" Mafalda asked with interest.

"Is there any difference between the two?" Harry looked at her with squinted eyes.

"You need to pay for the former, but I will pay you for the latter," Mafalda said as a matter of course.

"You can tell the difference," Harry was stunned for a moment, and said vaguely, "Well, it's an exclusive revelation, but it's also an advertisement..."

Half an hour later, all the members gradually came out of that state of concentration, looking exhausted. Harry distributed the prepared chocolates to them, "The professor asked me to tell you that he's not very proficient in magic yet."

"Where are the others?" Fred turned his head and looked around.

"I guess he's also in a frenzy, but he took the initiative to get into this state." Harry said faintly, "Next time his magic will probably be perfect."

"So sexy." George said with admiration.

Ginny yawned and asked with half-opened eyes, "Can I sleep on the mat for a while, Harry?"

"Let's go to the 'Centropy Must Exist' club," Luna said, "I transplanted a lot of plants, and it looks like a small garden there, and there's a hammock. Do you want to join us?" She turned her head and stared at Harry.

"...No, thank you." Harry said, and he said goodbye to Neville, Susan and the others. Finally, only a few people were left in the classroom.

"It's a bit scary, I mean this magic." Ron said with lingering fear: "I was affected unconsciously. I knew what I was doing, but I just didn't want to be distracted." Then he smiled again, "But the effect is also surprisingly good. I seem to have grasped the trick. My Patronus has already taken shape."

"Me too," Hermione said happily: "The professor said that it's difficult for me to condense strong emotions. Maybe I'm too calm. Maybe I should make myself more 'enthusiastic'."

Mafalda was the last to leave except for them. She gestured to Harry, "It's settled."

"What did you 'settled'?" Ron asked while eating chocolate.

"Draco Malfoy." Harry said softly. "Great," said Ron happily. "I can't wait to see him get beaten up - snooping in the girls' bathroom, that's enough for him to get into trouble! But he can't complain because we're helping him!" He was in a very good mood, as if he had eaten several bars of chocolate, and his face was beaming with joy.

"I didn't say his name." Harry shook his head.

"Oh." Ron's eyebrows drooped. "I bet he won't thank you for letting him off the hook on this matter."

Harry shrugged. "I don't expect anything in return."

In the evening, the hall was bustling. As usual, the Ministry of Magic stayed after dinner to guide the students who did not meet the assessment standards. "Work harder, there are less than a third of the students left." Tycross encouraged his colleague.

"I need a rest." Umbridge said coldly, and she walked out of the hall on her own.

"Wicky, I also want to go out for some fresh air... I'm too tired these days, sorry." Avery whispered, and then several people made excuses to leave, which made Tycross confused and discouraged. He stared at the other people from the Ministry, "Do you want to rest too?" This time, no one walked out again.

"Tycross, do you need help?" Professor Flitwick asked kindly.

"Oh, Professor Flitwick? It's your and Professor Snape's turn to be on duty today?" Tycross was overjoyed. "Thank you very much." Snape, who stood with Flitwick, remained silent. He stared at Umbridge and Avery as they passed the long dining table until they disappeared at the door of the Great Hall.

Voldemort did not reveal his undercover identity to the two of them, which made him secretly relieved, indicating that the Dark Lord seemed to have finally regained some sanity. Although it was not necessarily a good thing, at least he did not have to worry about him suddenly going crazy during a report...

On the other side, Umbridge and Avery walked out of the Great Hall and passed through the entrance hall one after another, and came to a dark corridor. They hid behind a huge pillar and muttered.

"You go!"

"Why not you?"

"I have a more important task!"

Varen, who was passing by from a distance, looked at them curiously. It smacked its lips and left with the little snake. It failed to negotiate with the Great Devil last night. Varen summed it up and thought that it was because it was too bad at mathematics. It wanted to find someone to help! The last time it asked Astoria, it knew that many students in the school were unreliable and might not be as good as it. It had to ask the right person.

As it happened, it knew a top student.

Umbridge and Avery peeked out from behind the pillar and stared at Valen's back.

"Do you think this little thing will help the plan?"

"You can try it. Once it succeeds, someone will open the door for you." Avery whispered, "I'll find another opportunity to contact Malfoy. If it doesn't work, there are backup candidates." He left from the other side of the stone pillar.

Umbridge stopped where she was, she was somewhat convinced.

The Ancient Rune Office was like a nest of horror in her mind, but it would undoubtedly be much more convenient if someone led the way.

She stood out from behind the pillar and carefully took out her wand. Her wand was very short, only eight inches, like a feather pen with hair lost, and looked inconspicuous. Umbridge approached step by step. She had heard about the deeds of this Niffler in the past few days. It was the pet of that person... Hatred surged in her heart.

Umbridge slowed down her breathing. She kept telling herself that she only needed a Confusion Charm, just like how she persuaded her father to retire early. It was easy.

She moved her mouth, and then a white light flashed. Umbridge almost thought she had succeeded. She controlled herself not to grin, but the development of the matter was beyond her understanding. The little yellow hat worn by the Niffler suddenly burst into a strong light, and the spell she was sure of was bounced away.

Valen, who was holding the little snake, stopped and turned his head in confusion. He saw a strange-looking short and fat woman holding a wand and freezing in place. Valen blinked and took off the little yellow hat. There was an obvious burn mark on the back of the hat, and a wisp of light black smoke came out.

"Chi?"

Valen stared at Umbridge fiercely.
