Chapter 153 Live Well, Harry
In the eyes of Harry and Sirius, they only saw that the moment Sherlock touched Snape, they suddenly disappeared together!

Silently, as if it was erased from the picture by an eraser out of thin air!
"What's going on! Where are Professor Forrest and Snape!" Harry said in shock.

Ron and Hermione couldn't answer his question either, because they didn't know what was going on.

"Never mind that! Run! Run!" Sirius had let go of Lupine by this time.

Lupine knelt on the ground, and the bright moonlight sprinkled on his body was like a deadly poison, causing drastic changes in his body!
Sirius took Harry and the others, and ran towards Hogwarts Castle together!

Lupine, who had completely turned into a beast, let out a long howl of a wolf in the moonlight!

Harry couldn't help but look back as he ran.

"Peter! Peter is still there!"

Sirius held on to him and didn't let go.

"Leave him alone! He's dead! Get back to Hogwarts before Lupine notices us!"

They ran wildly, not daring to stop for a moment, but just when they reached the Whooping Willow, an unrecognizable number of dementors in black robes floated down from the sky and surrounded them.

The coldness that was enough to freeze people made Harry almost freeze in place!

Black let go of Harry's hand suddenly, panting as he watched the dementors surround them.

Harry seemed to guess what he was thinking, he begged desperately.

"No! Sirius! You can't. They'll kill you! They'll kill you!"

Sirius, however, had a resolute face.

"When I escaped from Azkaban, I already thought of this outcome, Harry. To avenge your parents is already fulfilling my greatest wish!"

He broke free from Harry's hand and fled in the opposite direction from Hogwarts Castle.

Animagus is not used, because dementors have no eyes, they only rely on smell and human emotion to perceive the presence of the target, if he turns into a dog, then these dementors will definitely put the target on Harry on them.

"Call for protection!" Sirius recited the incantation of the Patronus Charm.

A silvery radiance lit up in front of him, but no Patronus was formed under his spell.

Just a faint silver phantom, just as Harry had been practicing.

These radiances couldn't disperse the locust-like dementor swarm at all, but Sirius still managed to push back the few dementors who stood in front of him.

He escaped from the siege of the dementors, but in fact he couldn't escape for long, because not only what was in front of him, but also groups of dementors were flying over outside, forming a denser encirclement towards him!
Harry looked at the direction in which Sirius was fleeing, and subconsciously started to take steps to catch up, but Hermione caught him just in time.

"They'll suck you dry if you follow!"

"But I just met him, and he said he would sign my agreement to leave school and take me to his house."

There were tears in Harry's eyes, and he didn't want to cry because he had cried enough today, but he couldn't help the tears in his eyes.

Hermione, Ron, and Harry broke into the gate of the castle. They leaned over the window of the corridor and saw the direction Sirius escaped from. Suddenly, a silver light lit up half the sky.

No one knew exactly what was going on with Sirius, if he was still alive, or if he had been captured by a dementor.

Harry knelt down on the ground, his eyes were empty, and his whole energy seemed to be drained.

Hermione and Ron looked at each other, they wanted to find something to comfort Harry, but at this moment they opened their mouths but couldn't say anything.

Just as they were in a daze in the corridor, a burst of messy footsteps sounded from upstairs.

Professor McGonagall, Minister of Magic Fudge, Filch and two other Ministry of Magic escorts left. They were originally planning to leave the castle, but they were obviously alarmed by the reaction of the dementors.

Seeing the dementors like a swarm of locusts outside, Fudge let out a cry of excitement.

"Aha! Those guys must have discovered it!"

Professor McGonagall looked at Harry and the others, her face was serious and her brows were tightly frowned.

"It's already curfew time, what are you still doing here? Go back to the lounge!"

Harry didn't listen to her, but hugged Professor McGonagall's leg excitedly!
"Professor! Go and save Sirius! He is innocent! He was wronged! The real murderer is Peter Pettigrew! Go and save him! Please! Ron, Hermione, they can all testify!"

"Yes, we can all testify professor!" Ron and Hermione also said hastily.

However, none of the adults present believed what they said. Fudge looked at them in surprise and muttered.

"Did they fall under Black's evil spell? Why did they say such a thing?"

"No! If you don't go there again! He's really going to die!"

But no one believed what Harry and the other children said. Professor McGonagall asked Filch to take them to the lounge, and Filch was naturally so happy.

Harry and the three of them were forced to go back to the Gryffindor lounge. Harry didn't go back to the dormitory, but sat in the lounge.

The most painful thing in the world is to have hope, and then the hope is ruthlessly broken in front of your eyes.

Both Ron and Hermione were by Harry's side, and they were now very concerned about his condition.

"We can go to Professor Dumbledore!" Harry stood up suddenly, as if he had thought of some straw.

"What can Dumbledore do for us?" Ron whispered.

But Harry didn't want to think about it now, Dumbledore was his last hope, he had to hold on to it, and he couldn't let anyone destroy it.

He took out the invisibility cloak, put it on himself and Hermione Ron, and sneaked out of the lounge together.

They went downstairs all the way down the stairs, and came to the stone monster on the third floor. Harry and the three of them didn't have a password, so they could only ask it.

"Help, we want to see Professor Dumbledore, please, let us meet him!"

The stone monster was silent, as if it was communicating with someone, and then it made way for Harry and the others.

Harry and the others didn't stop, and immediately walked along the spiral staircase to the principal's office on the eighth floor, pushed the door open and ran in hastily.

Dumbledore looked very surprised to see them coming in anxiously.

He put down the quill in his hand, looked at them, and comforted them softly.

"Don't be nervous, what else do you need to come to me so late? Shouldn't it be curfew time?"

Harry couldn't help being nervous, he was afraid that things would really be irreparable if he waited.

He spoke quickly and told Dumbledore the whole story, some of which were omitted due to nervousness, and Hermione and Ron added for him.

So soon, Dumbledore knew what was going on.

"Professor, can you tell those dementors not to kill Sirius?" Harry begged, "He was really wronged. It was Peter who killed my parents, not him at all!"

Dumbledore shook his head at Harry's desperate gaze.

"I have no way to order the Minister of Magic, and no one will believe what you say, they will only think that you were bewitched by Black with evil methods."

Harry stared into the stern face, feeling as though the ground was falling apart under his feet, accustomed to the idea that Dumbledore could solve any problem.

He was counting on Dumbledore to come up with a solution to the problem out of thin air, but no, the last hope was dashed.

"What we need now," said Dumbledore slowly, his pale blue eyes looking from Harry to Hermione, "is more time."

"But." Hermione began, and her eyes widened as if thinking of something, "Oh!"

Harry and Ron were confused by their conversation, but by this time Dumbledore had stood up from his seat, took out his pocket watch, and checked the time.

"It's [-]:[-] in the middle of the night, you need to turn four times." He lowered his voice, "I will leave this room first, if all goes well, you can save more than one innocent life tonight. But remember this , the three of you must remember. It must be hidden from view, Miss Granger, you understand the law, you know that something is dangerous, and it must not be seen."

Before Harry could figure out what was going on, Dumbledore had turned his back, and back again as he reached the door.

"Wish you guys good luck."

"Good luck?" Harry repeated, as the door closed behind Dumbledore. "Four times? What is he talking about? What are we supposed to do?"

Hermione groped excitedly at her neckline, and finally pulled out a fine gold chain.

Both Harry and Ron were still puzzled, but Hermione had already put the chain on the heads of the three of them together, and then the gold chain was completely pulled out, and there was a small pendant hanging from the gold chain. shiny gold timer.

Hermione didn't explain much, she just turned the timer back four times.

The softly lit headmaster's office was gone, and Harry and Ron felt like they were flying, fast, backwards.

All kinds of blurred clouds and shapes flashed before their eyes, something knocked in their ears, they wanted to speak, but they couldn't hear their own voices, and then they felt solid ground under their feet, everything came into focus again, and they stood Beside Hermione, standing in the empty headmaster's office.

"We are now back four hours ago, when we were about to go to Hagrid's cabin!" Hermione grabbed Harry and Ron's hands and led them out of the principal's room.

Harry and Ron still couldn't understand, Ron asked in disbelief.

"That timer can turn back time?"

"It's called a Time-Turner," whispered Hermione. "Put on the Invisibility Cloak, Harry."

The three of them put on the invisibility cloak and walked down the office, and Hermione had time to explain the Time-Turner to them.

"I got it from Professor McGonagall on the first day we came to school. You have to be a model student at Hogwarts to apply for it from the Ministry of Magic, and it can only be used for study. Professor McGonagall Swear not to let me tell you guys that's why I never said it, which is why I can take several classes at the same time!"

Harry's breathing became rapid.

"But even if we could go back in time, would it do anything to help Sirius?"

Hermione shook her head, she didn't know that either.

"At this time, Buckbeak has not been executed yet. We might be able to rescue him. We can rescue him first, and then wait for the rest."

The three of them managed to sneak behind Hagrid's hut through the invisibility cloak, and successfully released Buckbeak before the executioner from the Ministry of Magic arrived.

Then they quietly followed behind themselves four hours ago, and saw with their own eyes that they were blocked by the three of Sherlock.

"I looked so stupid," Harry muttered under the cloak.

They hid on the outskirts of the Forbidden Forest, not daring to get too close.

It wasn't until a group of people grabbed Peter out of the Forbidden Forest that they followed behind again.

Once again, they witnessed Sherlock and Snape disappear before their eyes, while Lupine turned into a werewolf and Sirius led them on the escape.

Harry and the others didn't immediately run with themselves four hours ago, but saw Lupine, who had turned into a werewolf, brutally bit Peter, who was lying unconscious on the ground!

Just after taking the first bite, Peter was woken up by the unbearable pain.

He screamed and struggled to sit up from the ground, but Lupine took the second bite without hesitation, and a large piece of flesh and skin was torn off Peter's shoulder!
With a piercing scream, the next moment Peter disappeared in place.

Harry knew he had turned into a mouse and slipped away. He raised his wand to keep Peter, but Hermione pulled him and said.

"Don't go, you will become a werewolf if you are bitten by a werewolf. This is more painful than death for a normal wizard."

They ran forward quickly, following Sirius and the others, and saw Sirius take the initiative to separate from them in order to distract the dementors.

"I understand."

Harry looked at the direction Sirius was escaping and muttered to himself, he thought of seeing that silver light that lit up half of the sky in the corridor!
Harry left the invisibility cloak to Hermione and Ron, broke into the night alone, and ran in the direction of Sirius.

"You guys are waiting for me here!"

The night wind was whistling beside him, and Harry's mind was full of images of Sherlock teaching him the Patronus Charm.

"Happy! Happy!" he kept muttering, getting closer and closer to the periphery of the dementor group.

He was thinking about his experience of traveling with Sherlock during the summer vacation; he was thinking about his bad birthday, but it was the only birthday that anyone remembered and was willing to give him in 13 years; He hesitated and told himself that he was actually the guardian appointed by Harry's parents, and he could let Harry live with him during the holidays.

Harry is looking forward to, he is looking forward to the future that will surely be better.

The coldness emanating from the dementor was constantly eroding him, and it seemed that his mother's voice sounded in his ears again.

But it was no longer desperate pleading and whining, she seemed to be speaking to him in her own ear.

"Live well, Harry."

Countless dementors surrounded him, and Harry could already see Sirius in the middle who had fallen to the ground, his whole body was blue, and even the Animagus couldn't use it.

He raised his wand, oblivious to the black-cloaked ghosts that surrounded him.

He was no longer afraid in his heart, he grabbed Sirius' cold hand, and chanted the spell aloud!
"Call God Guard!"

Brilliant silver light erupted from his wand, no longer a shapeless mist, but a dazzling silver animal!

The bright light almost illuminated half of the sky. A shining stag broke into the group of dementors. The dementors retreated, collapsed, and disappeared into the darkness. They fled in embarrassment!
"Wake up! Sirius! Wake up!"

Harry called his name, and under the silver light, Sirius opened his eyes, and he stared at Harry.

"Go!" Harry urged him, "Minister of Magic Fudge is coming, hurry up!"

Sirius gave Harry one last look.

"Wait until I write to you."

Then he turned into a big black dog and disappeared into the vast night.
