Expecto Patronum

Professor McGonagall held her wand with a solemn expression, only relaxing after seeing that Su Yu was unharmed.

"Oh, darling, are you alright?"

Professor McGonagall asked Su Yu with concern, even pulling on his arm to check if he had suffered any internal injuries, without even glancing at Grindelwald standing to the side. How could she not know that Professor Graves was Grindelwald? She just couldn't object.

"I'm fine, don't worry, Professor McGonagall," Su Yu said, glancing at the professors with his glasses. "Where's Professor Snape? I haven't seen him."

"Who knows? He left in a hurry after cleaning up those disgusting creatures," Professor McGonagall said, while gesturing for Madame Pomfrey to give Su Yu another thorough examination.

Professor McGonagall was only completely relieved after Madame Pomfrey assured her that Su Yu was perfectly fine, and then she called on the other professors to begin cleaning up the mess.

At this moment Ka-jie and Fa-jie, having finished inquiring about the situation of the entire Slytherin group, came to Su Yu's side to report. "Very good, no casualties. This teamwork was perfect."

However, Su Yu was still worried about Hermione's situation. After telling Professor McGonagall and the others, he led the Slytherin group to the Forbidden Forest to search for where Hermione and the others had gone.

Su Yu kept trying to recall where the two Hermione might be now. Reality isn't a movie, and besides, the movies didn't show where the second Hermione went...

His primary task now is to find the second Hermione. Finding the second Hermione would mean that nothing happened to the first Hermione. But if he goes to find the first Hermione first, he will still have to find the second Hermione to make sure that nothing happened to her either.

Oh! This jujube cake Time-Turner! The thought of it gave Su Yu a headache.

Hagrid's Hut! Yes, after Hermione and the others rescued Buckbeak, they had nowhere else to go but Hagrid's Hut, where no one was!

Su Yu activated his Tenseigan to its maximum, surveying everything around him. Finally, in Hagrid's Hut, he saw a second Hermione and Isolde with Buckbeak.

Su Yu flashed into Hagrid's Hut. His sudden appearance startled the Hermione Su Yu the second Isolde. Then, the two women felt themselves being pulled into Su Yu's arms.

Five minutes later, Hermione and the other woman finished drinking hot tea and recounted the events of the day to Su Yu in detail.

After today's exams, Harry, Ron, and Hermione went to the Shrieking Shack at night and unexpectedly encountered Sirius Black, who revealed that he was Harry's godfather and an innocent victim who had been wrongly accused. The real culprit who betrayed James and his wife and killed Muggle was Peter Pettigrew, who had been living as Scabbers and attached to Ron for many years.

Lupin then arrived and confessed his Werewolf identity. Together, they exposed Peter's disguise. Professor Snape had just participated in a major battle, also arrived, but due to exhaustion and being ambushed by Harry, he fainted. When the group returned to the Whomping Willow from Hogsmeade Village, the full moon caused Lupin, who had forgotten to take his medicine, to uncontrollably transform into Werewolf. At this moment, a man in black appeared, accompanied by a large number of Dementor. The Professor Snape desperately shielded the children behind him, and in doing so, he was severely injured while protecting Harry and the others.

Sirius was also seriously injured while protecting the others. If Isolde hadn't appeared in time, they would all be in Elphias Doge. Professor Snape begged Isolde to protect Harry, and then he fainted again.

Next, Isolde battles the Men in Black and a large number of Dementor, while Hermione fights Lupin, who has turned into Werewolf. However, in the chaos, the Men in Black manage to escape with Peter, and Harry faints while protecting Sirius from being devoured by the Dementor. In the end, Sirius is captured and told he will be executed that night.

In a critical moment, Hermione used the Time-Turner to take Harry and Isolde back in time, and the three rescued Buckbeak, Hippogriff. Their final goal was to help Sirius escape Hogwarts on Buckbeak that very night.

Su Yu sighed and asked Harry where he was.

"Oh no! I was so busy chatting with you that I forgot Harry just went to the lake by himself! He said he was going to find his dad! We have to get there right now!"

Hermione, who was eating a scones, suddenly stood up, grabbed Su Yu, and walked outside. They eventually found Harry shouting loudly by the lake.

"Expecto Patronum!"

Su Yu didn't understand why Harry Number Two shouted so loudly, but Harry Number One still didn't hear anything, and then he saw Harry Number One faint from exhaustion.

"What did you do?" Hermione released Su Yu's hand and asked angrily, "You said you were just looking!"

"I just saved our lives..." Harry said, suddenly noticing Su Yu behind him. "Su Yu! Come here quickly, we need to get behind the bushes right away, I'll explain."

Hermione and Su Yu opened their mouths again after hearing what had just happened.

Has anyone seen you?

"Yes, weren't you all listening the whole time? I saw myself, but I thought it was my dad! Do you understand? It's okay!"

Harry was rambling incoherently.

"Harry, I can't believe it... You summoned your Patronus and drove away all those Dementor! That's incredibly advanced magic..."

"I knew I could do it this time," Harry was still struggling with his own thoughts, "Because I've done it before...does that make sense?"

"I don't know, Harry. Look! Snape!"

The three of them peered across the river from behind the bushes. Snape, now awake, was dragging his badly injured body and conjuring a stretcher to carry the lifeless Harry and Black onto it.

Another stretcher was already hovering beside Snape, and Ron was undoubtedly on it. Then, Snape held his wand in front of him and carried the stretcher to the castle.

"Alright, it's almost time," Hermione said nervously, glancing at her watch. "We have about forty-five minutes before Headmaster Dumbledore locks the Hospital Wing doors. We must rescue Sirius in that time and get back to his ward before anyone discovers we're missing..."

"Um... if I may ask, why did you two go to such lengths... um... to rescue Sirius in this way?"

Su Yu, standing to the side, asked curiously, "Why do things secretly when you can explain them clearly? It's the same in the original story. The White Lord, the head of the Ministry of Magic worldwide, who governs all the wizards in Tenten world, was forced to abdicate by the United Kingdom Ministry of Magic. He's practically no different from a school principal, with no loyal followers. He has to do everything himself, and no one appreciates him. Voldemort, on the other hand, has a large following and knows to bring a group of people with him when he fights, let alone Grindelwald..."

There was only Dumbledore, but this group of people all had abnormal thought processes, which was Su Yu's feeling; it was like choosing the best among the worst.

Voldemort killed Dumbledore and instead of attacking the United Kingdom Ministry of Magic, he went to attack the schools. Grindelwald, with such a large power, didn't focus on developing it properly, but instead insisted on vying for the position of president of the International Ministry of Magic. It's like an American president who doesn't want to be president anymore, but insists on running for president of the United Nations, saying that the position is more powerful and can control the whole world. Su Yu silently gave them a thumbs up in his heart.
