In the eyes of Harry and Sirius, they only saw that the moment Sherlock touched Snape, the two of them suddenly disappeared!

Silently, it was as if it was erased from the picture out of thin air!

"What's going on! 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.

"Don't worry about those! Run! Run quickly!" Sirius had let go of Lupin at this time.

Lupin knelt on the ground, and the bright white moonlight spread on his body like a deadly poison, causing a drastic change in his body!

Sirius took Harry and the others to run towards Hogwarts Castle together!

Lupin, who had completely turned into a wild beast, heard a long wolf roar in the moonlight!

While Harry was running, he couldn't help but look back.

"Peter! Peter he is still there!"

Sirius grabbed him and did not let go.

"Don't worry about him! He's dead! Hurry back to Hogwarts before Lupin notices us!"

They ran wildly and did not dare to stop for a moment. However, just as they ran to the willow of beating people, they could not see the number of dementors in black robes floated down from the sky and surrounded them in the middle.

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

Black suddenly let go of Harry's hand, and he gasped, watching as he surrounded them.

Harry seemed to have guessed what he was thinking, and he begged in despair.

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

Sirius looked determined.

"When I escaped from Azkaban, I already thought of this result. Harry. Being able to avenge your parents has fulfilled my greatest wish!"

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

Animagus was not used because the dementors had no eyes, and they would only rely on smell and human emotions to perceive the existence of the target. If he became a dog, these dementors would definitely place their target on Harry and the others.

"Call the Gods Guardian!" Sirius recited the spell of the guardian god.

A silver light lit up in front of him, but no patron saint formed under his spell.

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

These brilliances could not dispel the dementor group like locusts, but Sirius successfully forced the few dementors blocking him.

He escaped from the siege of the dementors, but in fact he couldn't escape for long, because not only the ones in front of him, there were groups of dementors flying over outside, forming a denser encirclement towards him!

Harry looked at Sirius' escape direction and subconsciously took a step to catch up, but Hermione grabbed him in time.

"If you follow me, they will suck you dry!"

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

Harry held tears in his eyes. He didn't want to cry because he had cried enough today, but he still couldn't help but burst into tears in his eyes.

Hermione, Ron and Harry broke into the castle gate. They walked through the window of the corridor and saw Sirius' escape direction. Suddenly, a silver light illuminated half of the sky.

No one knows what Sirius is doing now, whether he is still alive or caught by a dementor.

Harry fell to the ground with his eyes empty, and his whole body's energy seemed to have been taken away.

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

Just as they were standing in the corridor, a messy footsteps sounded from the upstairs.

Professor McGonagall, Minister of Magic Foggy, Felch and two other escorts from the Ministry of Magic walked down. They were originally going to leave the castle, but now they were obviously shocked by the reactions of the dementors.

Seeing the dementor outside like a swarm of locusts, Fuji screamed excitedly.

"Ahhh! Those guys must have discovered it!"

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

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

Instead of listening to her, Harry hugged Professor McGonagall's legs excitedly!

"Professor! You go and save Sirius! He is innocent! He was wronged! The real murderer is actually Little Peter! Go and save him! Please! Ron, Hermione and the others can testify!"

"Yes, we can all testify as professors!" Ron and Hermione also hurriedly said.

However, no one of the adults present believed their words. Fudge looked at them in surprise and muttered.

"Did they get hit by Black's evil deeds? Why did they say such words?"

"No! If you can't go there again, he will really die!"

But no one believed Harry and the others' children. Professor McGonagall asked Felch to take them to the lounge, and Felch was naturally happy.

Harry and the other three were forced to return to Gryffindor's lounge. Harry did not return to the dormitory, but sat in the lounge.

The most painful thing in the world is that there is hope, and then hope is ruthlessly broken in front of you.

Ron and Hermione were with Harry, and they were worried about his condition now.

"We can go and find Professor Dumbledore!" Harry suddenly stood up, as if he had thought of some life-saving straw.

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

But Harry doesn't want to consider this now. Dumbledore is his last hope. He must seize this hope and cannot let anyone destroy it anymore.

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

They went downstairs along the stairs and came to the stone monster on the third floor. Harry and the others had no password and could only ask for it.

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

The stone monster remained silent, as if communicating with someone, and then it gave way to Harry and the others.

Harry and the others did not stop, and immediately followed the spiral staircase inside to the principal's office on the eighth floor, hurriedly pushed the door and ran in.

Dumbledore looked very surprised when they came in anxiously.

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

"Don't be nervous, what else do you have to look for me so late? It should be curfew time now, right?"

Harry had no choice but to be nervous. He was afraid that things would be irreversible if he waited.

He spoke quickly and told Dumbledore about the whole story. Some of the things were missing due to tension, and Hermione and Ron added to him.

So soon Dumbledore knew what was going on.

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

Dumbledore shook his head under Harry's desperate gaze.

"I have no way to command the Minister of Magic, and no one will believe what you said. They will only think that you have been deceived by Black with evil magic."

Harry stared at the serious face and felt that the ground under his feet seemed to be falling apart. He was used to the idea that Dumbledore could solve any problem.

He hoped Dumbledore could come up with a solution to the problem out of thin air, but no, the final hope was shattered.

"We need it now," Dumbledore said slowly, his light blue eyes seeing Hermione from Harry, "is more time."

"But..." Hermione began, and then her eyes widened, as if she had thought of something, "Oh!"

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

"It's midnight and it's 40 minutes, and you need to go around." He lowered his voice, "I will leave this room first. If everything goes well, you can save more than one innocent life tonight. But remember this, all three of you must remember. It must not be seen, Miss Granger, you know the law, you know what is dangerous, and you must not see it."

Before Harry could figure out how things were going, Dumbledore had turned around and turned back when he reached the door.

"Good luck to you."

"Good luck?" Harry repeated, and the door behind Dumbledore was closed, "Turn four times? What are he talking about? What should we do?"

Hermione was excited to explore the position of her neckline, and finally pulled out a fine gold chain.

Harry and Ron were still confused, but Hermione had already put the chain on the common heads of the three of them, and then the gold chain was completely pulled out, with a small shiny gold timer hanging under the gold chain.

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

The principal's office with soft lights disappeared, and Harry and Ron felt like they were flying, flying very quickly, and flew backwards.

All kinds of blurred clouds and shapes flashed before their eyes, something was knocking in their ears, they wanted to speak, but they could not hear their voices, and then they felt that the solid land was touching under their feet, and everything was focused again, they stood beside Hermione, in the office of the principal without anyone.

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

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

"Will that timer reverse time?"

"This is called a time converter." Hermione whispered, "Put on the invisibility cloak, Harry."

The three of them put on invisibility cloaks and walked down the office. Hermione also had time to explain the time converter to them.

"I got it from Professor McGonagall on the first day we came to school. I had to be a model student in Hogwarts to apply for it from the Ministry of Magic and only used for study. Professor McGonagall vowed not to let me tell you something, so I never said it, which is why I can take several courses at the same time!"

Harry's breathing began to get rapid.
