Hogwarts: The Savior's Strong Cousin

As soon as he entered the hall, Harry felt an unusual atmosphere. Students gathered in groups of three or four, whispering about something. Harry's good friends Hermione Granger and Ron Weasley were among them, and their faces were full of worry.

"Harry!" Hermione came over hurriedly, her face serious, "Have you heard?"

"What did you hear?" Harry asked, although he was already feeling vaguely uneasy.

"Professor McGonagall is missing." Ron said in a low voice, with anxiety in his eyes.

"What? This is impossible!" Harry said in shock. Professor McGonagall has always been strict and responsible, it is impossible for her to disappear without any reason.

"It's true," Hermione nodded, "No one has seen her this morning, and her office is a mess."

Harry was silent for a moment, various possibilities flashing through his mind. The three of them immediately decided to go to Professor McGonagall's office to look for clues.

Walking in the corridor leading to the office, Harry felt a chill, as if some kind of ominous premonition was shrouding the entire Hogwarts. The door of the office was half open, and it was a mess inside, with books and scrolls scattered all over the floor.

"It's obvious that someone is deliberately creating chaos," Hermione carefully observed the traces around her, "but why did Professor McGonagall disappear?"

Harry picked up a piece of paper on the ground. There were only a few words written on it: "Danger is coming."

"We must find out the truth," Harry said firmly, "This is a conspiracy against Hogwarts."

The three of them quickly launched an investigation. They first found Dumbledore, who also felt the seriousness of the situation. Dumbledore told them that the Ministry of Magic had also discovered some unusual activities recently, and it seemed that a dark force was ready to move.

As the investigation deepened, they found more clues that pointed to a mysterious dark wizard. It was rumored that this dark wizard was once a follower of Voldemort, and after Voldemort was defeated, he had been lurking in the dark, waiting for an opportunity to make a move.

One night, Harry, Hermione and Ron found an injured house elf at the edge of the Forbidden Forest. It was Professor McGonagall's assistant. The elf told them that Professor McGonagall had been captured by a dark wizard who intended to control Hogwarts through Professor McGonagall and look for some ancient and powerful magical relics.

"We can't let him succeed," Harry said firmly, "We must rescue Professor McGonagall and protect Hogwarts no matter what."

With the help of Dumbledore, they developed a daring plan. They decided to use an ancient teleportation spell to sneak into the dark wizard's hiding place. This plan is full of dangers, but it is their only chance.

In the darkness of night, Harry and his companions quietly walked through the corridors of Hogwarts and came to the edge of the Forbidden Forest. In the dark shadows of the trees, they cast a teleportation spell and disappeared instantly.

When they appeared again, they were already in a gloomy castle. The atmosphere was filled with darkness, and it seemed that danger was lurking in every corner. Harry held his wand tightly and led his companions forward carefully.

They encountered various traps and obstacles, but they resolved them one by one with wisdom and courage. Finally, they came to a huge and dim hall. In the center of the hall, Professor McGonagall was tied to a stone pillar, and the dark wizard stood next to her.

"Welcome, Harry Potter," the dark wizard sneered, "I have been waiting for you."

"Let her go!" Harry roared, pointing his wand at the Dark wizard.

"Do you think you can defeat me?" The dark wizard grinned and waved his wand. Black magic light instantly shot towards Harry.

The battle breaks out. The hall is ablaze with magic as Harry and the dark wizard engage in a fierce duel, while Hermione and Ron desperately try to rescue Professor McGonagall.

At the critical moment when Harry was about to be knocked down by the dark wizard, he suddenly remembered an ancient defensive spell that Dumbledore had taught him. He used all his strength to cast the spell, and a powerful light instantly enveloped him, blocking the dark wizard's attack.

The dark wizard was knocked back by the bright light, and Harry seized the opportunity to fight back. The dark wizard fell to the ground in pain, and his wand slipped from his hand. Harry rushed over quickly and crushed the wand.

"This is not over yet, Potter..." the dark wizard said hoarsely, and suddenly turned into a wisp of black smoke and disappeared into the air.

Professor McGonagall was finally rescued. Although she was injured, she still had a resolute look on her face. "You did a good job," she said with a smile, "but we still need to find out more of the truth."

Harry, Hermione and Ron know that the conspiracy of the dark wizards has not been fully revealed and Hogwarts is still facing a huge threat. But they have no intention of retreating, because they know that as long as they unite as one, they will be able to defeat all dark forces and protect their beloved school.

In the dim light of the early morning, Harry, Hermione and Ron walked through the vast courtyard of Hogwarts with heavy steps, their hearts still echoing with the fierce battle of last night and the cold voice of the dark wizard. Professor McGonagall had returned to her office, and although she was physically weak, her spirit was still strong. She insisted on continuing to teach the students, and this spirit deeply infected Harry and others.

"We did it, but it's not over yet," Harry muttered, his fingers gently stroking his wand.

"Yes, Harry," Hermione said gently, "we will need greater strength to face future threats."

"I agree," Ron nodded, "but how do we find that power?"

At this time, Dumbledore's voice came from behind, with a smile and infinite wisdom. "Perhaps, I can help you."

Harry turned around and saw Dumbledore's deep eyes, and felt a warmth and strength in his heart. "Professor, what should we do?"

"Follow me," Dumbledore said briefly, turning and walking deeper into the castle. The three followed him through several winding corridors and finally came to a huge and ancient door.

"Behind this door lies a Hallow," Dumbledore explained. "It will give you the power you need, but only a true warrior can wield it."

Harry's heart beat faster, and many questions and expectations flashed through his mind. He knew the importance of the Hallows and understood that this was a huge test. Hermione and Ron were also nervous, but there was a firm light in their eyes.

"We're ready, Professor," Harry said firmly.

Dumbledore nodded and gently pushed the door open. Behind the door was an ancient room with a box shining with mysterious light in the middle. Harry felt a strong power emanating from the box, as if calling him.
