The Legend of Harry Potter Schoolmaster

Severus Snape struggled to get up from the ground, he restrained Sirius Black with ropes, dragged him behind him, tied the unconscious Harry and Hermione together, carried on his back, and finally He picked up Ron, who was completely unconscious with a broken leg, near the punching willow.

Jon and Dumbledore, who had been on the edge of the Forbidden Forest, watched him quietly.

"Looks like Severus will take care of them!" Dumbledore whispered.

"Black...isn't he innocent?" Jon asked tentatively.

"Yes." Dumbledore nodded. "It looks like we can save more than one innocent life tonight."

Snape made an effort to lead the three towards the castle, where he encountered Connelly Fudge and a group of Dementors hurriedly arriving.

After a brief exchange, he handed Black over to Fudge, and then carried the three students to the school hospital.

"What shall we do, Professor?" Jon asked hastily.

He no longer knows the direction of the plot development... Until now, Harry and Hermione, who used the time converter, still did not appear.

Dumbledore calmly took out his wand, and strands of silver threads gradually formed his Patronus of the Phoenix... Dumbledore whispered a few words to his Patronus, and then the silver phoenix flew over the castle.

"I sent a letter to Minerva and Filius!" Dumbledore explained. "Tell them that Black is innocent; when Connelly holds Black temporarily, they will both go and knock down the guards. Guard, save him!"

"Professor McGonagall and Professor Flitwick?" Jon said in surprise... If it was the two teachers, they would easily be able to rescue Black who was imprisoned in the Ravenclaw tower...

"Yes, they trust me...and Buckbeak." Dumbledore glanced at the hippogriff again. "It should also leave with Black."

"Finally, we have to do some aftermath work!" Dumbledore murmured: "Peter gave me a very important message, so someone must take responsibility for all this... otherwise it will bring a little trouble , because if I'm here, Peter can't escape, he'll be suspected!"

"You mean I'll surrender to the Ministry of Magic?" Jon stammered.

"I have no objection to you doing this." Dumbledore blinked: "If you are willing to stay in Azkaban for a few years, when your sentence is completed, I will personally take you out of prison!"

"Professor... are you kidding..." Jon squeezed out an ugly smile.

"Of course..." Dumbledore continued to ponder: "It doesn't have to be known to everyone... so..."

Dumbledore's pale blue eyes gleamed, and he seemed to have an idea: "I'll tell Ferius and Minerva to turn them into Mr. Potter and Miss Granger, with Buckby Go and rescue Blake!"

"Professor, what do you mean..."

"The Department of Mysteries at the Ministry of Magic has a magic tool called a 'time shifter' that allows wizards to travel back a few hours in the past, although such a time-travel is, in a sense, an illusory dream, which cannot change anything at all. Things!" Dumbledore said to himself: "However, Tom obviously doesn't know that much about it, he's been terrible at it!"

Dumbledore took a few steps forward, then glanced back at Jon and said meaningfully: "A few months ago, when I corresponded with a friend of mine who was in exile in Corsica, he told me, Your mastery of memory magic is very good!"

After speaking, Dumbledore walked towards the castle.

Jon got it all, a smile on his face.

It was himself who rescued Buckbeak, it was Snape who cast out a hundred Dementors, and it was McGonagall and Flitwick who released Black from the cell... so...

He asked, "Professor, can I visit Miss Granger in the school hospital in an hour?"

"sure!"

...

Jon Hart showed up at Hogwarts Hospital around nine o'clock at night.

"I heard my friend Miss Hermione Granger was injured, can I visit her?" Jon asked calmly.

"Yes, but not too long!" Madam Pomfrey said sternly, and she took Jon to the ward where Harry, Ron, and Hermione were.

Both Harry and Hermione fell into a complete coma, and Ron seemed to wake up a little, but unfortunately his sheets were red with blood and moaned in pain from time to time.

"Sir Merlin, second class, no problem. First class, if I can get it!"

"Thank you very much indeed, Minister."

There was a conversation between Fudge and Snape from outside the door.

Then, Albus Dumbledore pushed in the door.

"For God's sake, they need to rest!" Madam Pomfrey came over and shouted hysterically, "Is this a school hospital?"

"Yes, Poppy..." Dumbledore smiled: "Daris just told me a way to treat a broken leg, I think it may be effective for you and Mr. Weasley..."

"Principal Dalys-Derwent?" Madam Pomfrey said excitedly, "Professor Dumbledore, you must teach me!"

"certainly!"

The two of them pushed Ron's bed into a ward in the school hospital.

"You have to leave now!" Madam Pomfrey glanced at Jon before leaving.

"Of course, ma'am..." Jon nodded. "I say goodbye to her!"

"Poppy, hurry up!" Dumbledore urged in the inner ward.

With Madam Pomfrey's departure, only Jon and the unconscious Harry and Hermione were left in the ward.

Jon took a few steps forward, drew his wand, and aimed it at Harry Potter's forehead:

"Obliviate!"

With the disappearance of several silver threads, he walked to Hermione Granger's bed again:

"Obliviate!"

Harry's memory only needs to be revised for a short period; but Hermione's memory needs to be revised for the past year.

Straws of silver thread were drawn from Hermione's temple and back inside... Jon's wand was held steady, not shaking at all.

"I have to go outside to get some medicine!" Madam Pomfrey's voice came from the ward inside.

"Let me go, you continue to look after Mr. Weasley!" said Dumbledore.

After almost ten minutes passed, Jon finally put down his wand.

He took out the pendant on his chest that the house-elves had given him, then pulled off Hermione's collar and hung the pendant around her neck.

Then, he pulled up Hermione's clothes and covered the quilt.

"From today onwards, you will be called a time changer!"

This is the sixth chapter. I have something to do in the afternoon. The later update may have to wait until the evening...
