Hagrid was the first to come out of the house, holding Ron, followed by another Hermione. Then, a short man who was tied up tightly floated out. He was in an upside-down position, upside down, and his head hit the stone from time to time. "Ouch!"

The short man's face was swollen. His hands were tied behind his back and twisted together. His clothes were tattered. In order to avoid the stone, he tilted his head to one side strangely.

"Sirius, please..."

"You deserve it, Peter! You should be thankful that Harry is kind enough..."

A wand stretched out, revealing Sirius's alert face. He limped, and Harry and Lupin supported him on the left and right. Snape walked last. His expression was intriguing, and the wand in his hand was always pointed at Peter Pettigrew.

"Sirius, you should go to the hospital." Harry whispered.

"No! I want to see him convicted with my own eyes!" Sirius grinned, "It's better to give him another Dementor kiss." His wand drooped down, and Peter Pettigrew let out a sharp cry of pain.

...

Hermione hid behind the huge pumpkin and looked around, "Professor, should we do something? Professor McGonagall warned me not to change the past."

"I think we should be cautious, but..." Felix gently hooked his fingers, and a small stone silently stuck to Peter Pettigrew who fell again.

Until they were far away, Felix and Hermione walked out from the dark.

"Professor, what did you do just now?"

"I used magic to mark Peter Pettigrew just in case. You just said that they would be trapped on the covered bridge. If he turns into a rat and escapes in the chaos, I can find him!"

Hermione thought about it seriously and thought it was a good idea.

The two of them were far behind these people. Hagrid took big steps and soon left the people behind him behind. The "other Hermione" who followed him had to trot after him.

Hermione said with a strange look in her eyes: "From this angle, I looked so stupid. For every one step Hagrid took, I took three steps."

Felix laughed softly, but soon his expression became serious: "I don't want to touch the forbidden zone of time, so my plan is to let everything move forward 'step by step' until the future you see arrives, and then I will appear."

Hermione nodded. This should be the best way. She imagined: half an hour later, when the Dementor army launched an attack on the covered bridge, Professor Hepp suddenly appeared and saved everyone in one fell swoop.

It did not change what happened in the past, but it really affected the future.

The two walked slowly, keeping a distance of two to three hundred feet from Harry and the others. Felix asked, "I have a few more questions. How did you hear the conversation between Umbridge and Fudge?"

Hermione explained, "I followed Hagrid to the hospital ward. Madam Pomfrey said Ron was not in danger, so I turned back to see Harry and the others. I unexpectedly saw Umbridge greet Fudge, and a group of Aurors followed him."

She said angrily, "That woman is so rude. She relied on the power of the Minister of Magic to be particularly rude to Professor McGonagall. If it weren't for Headmaster Dumbledore not being here..."

"She had a conflict with Professor McGonagall?"

"Yes, Professor McGonagall questioned her why she put the Dementors into the school, but Umbridge didn't even look at her. She was only concerned with flattering Fudge."

"Is that so..."

Felix looked ahead. With Sirius, the injured, the few people didn't walk very fast. Especially since they had to go through an uphill slope, which made their speed even slower.

The wind carried their conversation to one ear. It was Sirius's tangled voice: "I don't know if anyone has told you, Harry, that I'm your godfather..."

Ten minutes later ,

"Here it comes!"

Felix suddenly broke the silence. Hermione looked in the direction of his sight and vaguely saw a pink, round shape. She said in surprise: "Is it that woman?"

Then they heard a long whistle. Hermione felt a chill on her back. A black object floated out, like a black plastic bag blown by the wind. It quickly flew towards Harry and the others. At this time, Harry and the others were still some distance away from the covered bridge. Hermione took a deep

breath. More and more Dementors appeared. They were like a black plague, responding to Umbridge's call and covering half of the sky.

"It's a Dementor!" She heard Professor Lupin's voice in the distance, "How could there be a Dementor in the school? The Ministry of Magic has promised... Use the Patronus Charm!"

At this time, the sky was close to dusk, and the rosy clouds were half-covered. Half of the light was swallowed up. The Dementors hung high in the air, constantly spraying black mist, as if entering the night in advance.

Silver light pierced the darkness. It was Lupin's spell. He held up a silver barrier, but it was an incomplete Patronus.

Not far from them, "Let's get closer," Felix said, and he covered the two of them with a layer of light silver light.

"Professor, what is this?" Hermione looked at her glowing hand.

"Unpleasant memories, Dementors will subconsciously avoid us, of course, provided that they have a better choice." Felix said.

The two came close, close enough to see the expressions on Lupin's faces. Lupin shouted anxiously: "Harry, Sirius, use the Patronus Charm quickly, and Severus...if you can!" The

silver barrier he held up continued to condense, and a huge physical Patronus appeared. It was a wolf. Lupin hated it the most, but he had to use it at this moment.

With the appearance of the wolf-shaped Patronus, the crisis was temporarily alleviated. The silver giant wolf roared silently, jumping and slapping Dementors one after another.

Harry's mind cleared up for a moment. His lips trembled as he subconsciously chanted the spell: "Expo Patronus, Exo Patronus!" A silver mist flew out from the tip of the wand. With the faint light of the unformed Patronus, he felt better. The initial feeling of suffocation disappeared and he breathed deeply.

"Not enough! Not enough..." Lupin shouted: "Sirius, Severus!"

However, Snape did not move. His expression was stiff, and he clenched the wand tightly in his hand, with his joints white.

Sirius tapped one leg lightly on the ground. He raised his wand high and kept chanting: "Expo Patronus! Exo Patronus! Exo Patronus... Damn it, I can't do it!"

"What do you mean you can't do it? We learned it together." Lupin shouted.

"I can't help it... Those happy memories are all related to James." Sirius covered his face in pain. Under the influence of the Dementors, his lips turned purple like Snape's.

Harry looked at Sirius, as if he had known this man for the first time, and truly recognized his godfather status. He mustered up his courage, recalling all kinds of happy memories, the silver light kept surging, and something gradually took shape.

But there were too many Dementors, "Let's go to the bridge!" Lupin said decisively.

The tied-up Peter Pettigrew was put straight, and he rolled his eyes, constantly thinking about the escape route, "Be honest, Peter! There's a cliff below..." Sirius threatened, pushed him hard, and let him walk by himself.

The green light on Snape's wand disappeared, and he glared at Sirius fiercely, which made Sirius puzzled.

They boarded the covered bridge and retreated while fighting. Lupin was the only one with a complete fighting force on the field, but his Patronus could not fight against hundreds of Dementors, especially when they kept spewing black smoke. The biting cold made everyone's breath steam, and they felt like they were going to be frozen.

Snape sent several red rays of light to the sky, his face darkening, "Others will come, they will definitely..."

...

While all the Dementors were attracted away, Felix whispered to the person beside him, "When time returns to normal, you should appear on the other side of the bridge?"

"Yes, I followed the people from the Ministry of Magic. I took a look from a distance, then I hid and used the time-turner." Hermione said, she looked at the bridge anxiously, "It should be soon... People from the Ministry of Magic are coming."

"You should worry about yourself! When people from the Ministry of Magic come, how will you pass the bridge and get to the other side?" Felix said calmly, "If I remember correctly, you should return to the original position after using the time-turner?"

Hermione looked at him in surprise, "You are right, professor, a closed loop in time and space must be formed." She suddenly realized the problem and screamed, "Then what should I do, God! If I can't get back in time, I, I..." She thought of the consequences of abusing the time-turner she had seen, and shuddered in fear.

"How long did it take from the last time you saw Harry and the others to the

time you used the time-turner?" "About seven or eight minutes! Many students came over at that time, and I had to avoid them and hide in a bathroom to use the time-turner."

"Enough. I will create an opportunity for you... When you wear the invisibility cloak, with the help of the Disillusionment Charm, you should be able to hide it." Felix looked at her seriously, "You must seize the opportunity."

Hermione nodded heavily. She didn't know what the professor was going to do, but she trusted him without reservation.

"You stay here first, it's best to put on the invisibility cloak now, and be ready at any time..."

Hermione hurriedly put on the invisibility cloak, and Felix cast various spells to block smells and sounds for her. She looked as if she didn't exist.

Then, Felix walked onto the corridor bridge with the Disillusionment Charm.

There was a sound of footsteps from the other side of the bridge. Umbridge's pink clothes were very conspicuous. She appeared with a smile on her face and led a dozen Aurors. She said in a shrill voice: "Minister, it's just in front!" The short, fat and sturdy figure at the head was the Minister of Magic Cornelius Fudge.

Professor McGonagall followed him. She took a look at the scene on the corridor bridge and her eyes widened immediately. "Minister Fudge, you have to stop these Dementors! They are attacking the professors of Hogwarts, two of them!"

Umbridge chuckled. "That's because they are mixed with the most vicious fugitives from Azkaban. Look, they are also attacking members of the Ministry of Magic... Minerva, I thought you wouldn't protect them."

"Severus and Remus won't protect fugitives!" McGonagall said angrily.

Fudge patted his belly. "Don't worry, Minerva, we can control the Dementors and won't hurt these two professors. Otherwise, I can't explain to Dumbledore..."

He signaled Umbridge with his eyes. Umbridge took out a black whistle from her pocket and blew it with her cheeks puffed up. She looked like a toad ready to go and prepare to hunt.

The whistle sounded, and the Dementors received the command. Their attack became more fierce, constantly shuttling and flying in the gaps on the corridor bridge, and ice crystals condensed in the air.

Wisps of black mist were blown by the wind towards the people from the Ministry of Magic. Fudge shuddered and muttered in a low voice, "Disgusting things." He tightened his collar and stared at the bridge. The professor named Snape shot invisible spells from his wand. Miraculously, it could slightly block the pace of the Dementors' attack.

But... Fudge stretched out his thick fingers, "Who is the tied up man?"

Professor McGonagall looked at him carefully for a moment and exclaimed, "It's Peter Pettigrew!"

"How is it possible? Isn't he dead?" Fudge asked in doubt. He felt something was wrong. It seemed that someone who had been dead for more than ten years suddenly appeared. It was not normal no matter how he thought about it.

Umbridge rolled her eyes, "Minister, maybe the hero is not dead, but just lost his memory. He recently saw the news of Sirius Black's escape from prison, which stimulated him to recover his memory and decided to fight against the powerful enemy from more than ten years ago again..."

Fudge's eyes lit up, "You are right"

"No!" Professor McGonagall said suddenly, "Peter Pettigrew is an illegal Animagus. He disguised himself as a mouse and stayed in the home of one of my students for more than ten years! Dumbledore suspected that someone else betrayed the Potters. Minister Fudge, you should stop attacking and find out the truth."

Fudge frowned and said uneasily, "What are you talking about? Peter Pettigrew is a hero recognized by the Ministry of Magic and a winner of the Order of Merlin, First Class. How could it be possible..."

But he knew Professor McGonagall's character, she never lied, Fudge was a little undecided, and he looked at the battle on the bridge hesitantly.

At this moment, it has reached the most critical moment. Snape has been using hidden black magic, which has little effect on the Dementors and can only barely hold on.

The Dementors became more and more aggressive, and the flames thrown by Sirius became weaker and weaker. Finally, one of the Dementors flew past him and swept away his only remaining happy memories.

"No!" His wand dropped.

There was a gap in the defense, and more Dementors pounced on him. The silver mist that Harry held up became thinner and thinner. He felt like he was holding up a mountain and bent over under the burden.

Various hallucinations began to appear in his mind. He heard his mother's voice again, and this time it was particularly clear. He tried his best to resist, but his reaction became weaker and weaker.

Then, Harry found himself surrounded by a warm force, and he heard a gentle voice saying, "Harry, cheer up, think about the happy memories..."

Harry found himself free from the influence of the Dementors. He regained consciousness and quickly scanned the surroundings. He keenly noticed that the tip of Snape's wand was brewing a silver light, but he didn't have time to think about it. Seven or eight steps away from him, he saw his godfather lying on the ground. A Dementor leaned over and approached, lifted the tattered hood on his head, revealing a rotten hole that looked like a mouth. He even smelled the rotten breath.

"No, no!" Harry tried hard to imagine the feeling of having a new home and the scene of living with his godfather. "Expecto Patronus!" He shouted. He felt unprecedented power surging. Magic power continued to gather. Silver mist rolled like continuous waves. A dazzling silver creature walked out of the sea. It just stood still, and silver ripples spread out, throwing the Dementors far away.

Then, it began to run around Harry in circles, and its huge silver horns knocked Dementors away one after another. The Dementors army kept retreating and was in disarray.

Umbridge and Fudge were so surprised that they couldn't close their mouths. "Is this Harry Potter?" Fudge said strangely.

Umbridge was stunned for a moment, picked up the whistle and blew it hard, urging the Dementors to attack.

"Old woman, what do you want to do!"

Unconsciously, a group of students surrounded them behind them. They said indignantly, and a spell flew out from the corner and hit Umbridge's black whistle directly. The whistle exploded with a "bang", and Umbridge screamed and fell to the ground.

"Who! Who attacked the high-ranking officials of the Ministry of Magic!" Fudge said angrily.

Professor McGonagall raised her wand, followed by the students surrounding her. She suppressed her anger and said sternly: "Minister Fudge, order the Dementors to stop attacking immediately. If anything goes wrong, you will regret it."

Fudge looked around blankly. He had never been pointed at by so many wands. What he saw was a group of young and angry faces. Even the elite Aurors he brought with him had no fighting spirit at all. They could not attack the students.

Fudge's attitude softened, and he tried to defend himself: "I'm actually... not..." He was stunned for a few seconds, turned around, and ordered loudly: "Send the Dementors back, Aurors out, don't hurt anyone!"

A subordinate next to him whispered: "Minister, the whistle that controls the Dementors exploded."

Fudge was furious: "Can't the Dementors be controlled without that damn whistle?"

The man said in horror: "Normally, they can, but now they are seriously injured and urgently need to eat..."

Fudge's pupils dilated for a moment, as if in response to these words, the scattered Dementors gathered again, they did not die, but their robes became more and more tattered, and several of them had big holes on their chests.

This was caused by Harry's Patronus, but it was not a fatal injury, not even a minor injury. The body is dispensable to the Dementors, but they feel hungry, and there is a feast in front of them.

They aimed at the students behind the Auror and kept circling, like black birds announcing death, but facing their former controllers, they seemed a little worried. They sucked the air from the periphery, and the temperature dropped visibly. Many students exhaled puffs of white mist with pale faces.

On the other side, Harry leaned against the fence, breathing heavily. He was exhausted and barely managed to keep himself from falling down. The Patronus jogged back to him. It was not a horse or a unicorn, but a stag. It was glowing all over, and when he reached out to touch the sharp horns on its head, the Patronus dissipated.

Success! He successfully saved Sirius, Professor Lupin, and... Snape. Harry's eyes swept around. His godfather was lying on the ground, breathing heavily, with an expression of surviving a disaster on his face. Lupin sat on the ground tiredly.

He turned his head to look at Snape, and saw Snape dragging his shaky body, waving his wand like a sharp blade, and shooting a heart-pounding green spell from the tip of the wand. He suddenly widened his eyes, and reality seemed to overlap with dreams. He heard his mother's scream again, followed by a green light that filled his vision...

That was the Avada Kedavra curse!

How could Snape use this spell? No, who was he using it on?

Harry realized belatedly that Peter Pettigrew had disappeared, leaving only his clothes on the ground. His sight followed the direction of Snape's spell and saw a black mouse desperately fleeing.

Snape wanted to kill Peter Pettigrew!

But at this moment, a hand appeared from thin air and grasped Snape's wand, "Severus, he doesn't deserve this."

"Don't stop me, Felix!" Snape's face was twisted, and there was deep hatred in his eyes, stronger than anything Harry had ever seen, "Let me complete my revenge... I beg you!"

"There is a better way." Felix said, and he cast a spell. The mouse's body suddenly lit up, its head stretched, and so did its torso. It broke free from the Animagus state and stumbled to its knees.

Peter Pettigrew was extremely unlucky. He had just run to the other end of the corridor bridge, and a dozen steps away was a group of Aurors and students. They were originally staring at the restless Dementors anxiously, but at this moment they could not help but be attracted by this sudden scene.

Seven or eight Dementors slid down, one of them grabbed Peter Pettigrew's neck and loosened the hood on his face.

"No! Spare me, I shouldn't betray you, James, Lily, it was the Dark Lord who forced me to do it, he's too strong... you don't know his methods!" Peter Pettigrew shouted desperately.

The Aurors of the Ministry of Magic widened their eyes, their wands hanging in the air, including McGonagall, everyone froze in place, they were all shocked by Peter Pettigrew's sudden shocking remarks.

At the end of his life, he seemed to wake up and shouted desperately: "He's coming back! The man who can't even be named is coming back! I did something wrong, forgive me"

His voice stopped abruptly, and the Dementors sucked away his soul.

Snape took a few steps back, fell to the ground in a daze, and the whole person seemed to be paralyzed. He covered his face and muttered to himself.

After a long while, Fudge shouted, "Ridiculous! What is he talking about in his sleep!"

Professor McGonagall said tartly, "Only you think so, he has made it clear enough. Also, your Dementors are out of control!"

The Dementors were really out of control. Peter Pettigrew's soul stimulated them. They were not satisfied with hovering outside the feast and drinking some soup. They began to approach tentatively.

Fudge retreated in fear and shrank himself in the crowd: "Protect me, use the Patronus Charm!"

But unfortunately, the Patronus Charm is not a regular spell. Even the Aurors would not require this spell. Including McGonagall, there were only four people who knew the Patronus Charm.

McGonagall frowned. She didn't expect the Ministry of Magic to be so terrible, especially the Minister of Magic Fudge, who looked scared. She controlled her Patronus, just like Harry did, and the strong light continued to gather, but she heard Felix's voice.

"Now!"

What now? She turned around and opened her mouth in surprise. Felix stood on the edge of the covered bridge, holding a colorless transparent vortex in his hand. Blue magic was surging around his body. Dementors were torn off one by one, shrinking and falling into the vortex.

One, two, ten, twenty... These Dementors moved away from them uncontrollably, falling from the sky like black rain...

Felix maintained the magic and heard light footsteps passing by. It was Hermione wearing an invisibility cloak. He curled his lips, "You caught the opportunity very well, Miss Granger."

"Thank you, Professor." Hermione said softly.

She carefully avoided the Aurors and Professor McGonagall and passed through a group of students. "Who bumped into me?" Someone muttered in dissatisfaction, "Don't push, we can see clearly, Professor Happ is so cool, and there is Harry's Patronus, my God, it's incredible!"

After more than ten seconds, there was no more Dementors in the sky. Felix held the spherical vortex, looked at the stunned Minister of Magic and Aurors, and said softly: "Since these Dementors are out of control and attack students and the Minister of Magic, there is no need to keep them..."

"Boom!"

A white flame ignited in the spherical vortex, and the vortex began to rotate violently. Large amounts of black smoke poured out, transforming into distorted faces, but they were soon burned out by the flames. The black spots in the vortex disappeared one by one, as if they had never appeared.

Umbridge opened her eyes with blood in her mouth and saw the scene of Felix burning the Dementors. The past memories emerged, and she screamed and fainted.

"H-Mr. Happ..." Fudge said tremblingly.

Felix showed his white teeth, "You're welcome, this is what I should do."
