Hogwarts: The Savior's Strong Cousin

Harry looked at his wand and felt a sense of satisfaction. His control over magic had clearly improved, but he knew it was not enough and he needed more power.

"Harry, what are you doing here?" A familiar voice came from behind, interrupting his thoughts. Harry turned around and saw Hermione and Ron walking towards him with concerned expressions on their faces.

"I'm practicing my wand's power," Harry explained, "We need to become stronger to deal with the upcoming danger."

Hermione nodded, "I understand where you're coming from, Harry. We do need to step up our training, but we also need to be careful not to overexert ourselves."

Ron patted Harry on the shoulder and said, "Hey, man, we can practice together. I also want to improve my magical skills."

Harry looked at his friends gratefully, "Thank you. Let's practice together, it will be more efficient."

In the next few days, Harry, Hermione and Ron took time out every day to practice together. They chose the edge of the Forbidden Forest as the practice site, where there were few people and it was not easy to be disturbed. Everyone devoted themselves to improving their magic level.

One evening, they were practicing a difficult defensive spell when suddenly a strong magical wave came from deep in the forest, interrupting their practice.

"Did you feel it?" Hermione asked nervously, a hint of worry in her eyes.

"Yes, I felt it," Harry nodded, frowning, "What was that?"

Ron frowned, "It doesn't look like an ordinary magical fluctuation. Should we go and take a look?"

Harry thought for a moment and finally nodded, "We must find out what happened. This may be related to the conspiracy of the Ministry of Magic."

They walked cautiously towards the source of the magic fluctuations. The closer they got, the stronger the fluctuations became. Finally, they saw a strange scene in an open space - a wizard in a black robe was casting a powerful magic. A circle of blue light surrounded him, as if he was performing some mysterious ritual.

"Who is that?" Hermione asked in a low voice, her eyes full of surprise.

Harry observed the wizard carefully and suddenly remembered some rumors. "I've heard of him. He is an ancient dark wizard. It is said that he has mastered many long-lost magics."

Ron's face turned serious, "We must stop him. This magic is too dangerous."

Harry nodded. "Let's split up. I'll attract his attention from the front, and you guys will flank him from both sides."

They quietly dispersed, Harry raised his wand and walked towards the wizard. The wizard noticed someone approaching, turned to look at Harry, and a sneer flashed in his eyes.

"Who are you? How dare you disturb my ceremony!" the wizard said in a low voice, his voice full of threats.

"I'm Harry Potter," Harry replied firmly, "I will not allow you to perform Dark Arts here."

The wizard's eyes turned cold, "Harry Potter? How dare you challenge me! Then, let me see your strength!"

As soon as he finished speaking, the wizard swung his wand violently, and a strong black light came straight towards Harry. Harry reacted quickly and cast a defensive spell, barely blocking the attack, but he felt a huge force impacting his body.

"Now!" Harry shouted, and Hermione and Ron rushed out from both sides, casting powerful spells. The wizard was caught off guard and was hit by two spells. His body was shaken for a while, but he quickly recovered, and a flash of anger flashed in his eyes.

"Do you think you can defeat me like this?" The wizard laughed wildly, raising his wand, preparing to cast more powerful magic.

At this critical moment, Harry concentrated all his strength and cast the powerful flying magic he had recently learned. His body instantly flew into the air, avoiding the wizard's attack, and then swooped down from the air and rushed directly towards the wizard.

The wizard had not expected Harry to take such action, and before he could react, Harry punched him in the chest and he fell heavily to the ground. His wand slipped from his hand, and the magic light disappeared instantly.

"We did it!" Ron shouted excitedly, running towards Harry.

Hermione also breathed a sigh of relief, "Harry, you are so awesome!"

Harry gasped and helped the fallen wizard up, "We need to hand him over to Dumbledore. He will be able to handle this."

They quickly brought the wizard back to Hogwarts and handed him over to Dumbledore. After listening to their description, Dumbledore smiled and nodded, "You did a great job, Harry, Hermione, Ron. Not only did you protect Hogwarts, you also prevented a possible disaster."

Harry felt a sense of satisfaction and pride. He knew that this victory was not only an improvement in magical power, but also the result of their teamwork. There were still many challenges waiting for them in the future, but he and his friends were ready.

Harry Potter stood on the tower of Hogwarts, gazing at the dark forest in the distance. The night sky was full of stars, but his heart was filled with mixed emotions. Although he had won the battle against the dark wizard during the day, he knew that things were far from over. The dark wizard was temporarily controlled by Dumbledore, but Harry felt a little uneasy in his heart.

The next morning, Harry came to the headmaster's office. He had to find out the background of the dark wizard and his true intentions. Dumbledore was discussing things with several professors, and when he saw Harry come in, he smiled and motioned for him to sit down.

"Harry, do you have anything to ask me?" Dumbledore asked gently.

Harry nodded, "Yes, Professor. I would like to know more about the dark wizard from yesterday. Why would he perform that kind of magic near Hogwarts?"

Dumbledore sighed, "His name is Selwyn, an ancient and powerful dark wizard. He once caused quite a stir in the wizarding world, but then disappeared. His recent appearance may be related to the turmoil in the Ministry of Magic."

Harry frowned, "What should we do then? We can't let him continue to threaten Hogwarts."

Dumbledore nodded, "You are right, Harry. We must take action. However, Selwyn's power is not something that can be easily countered."

Just then, there was a knock on the door. The door opened, and Hermione and Ron walked in, with worried looks on their faces.

"Harry, we heard you were here, so we came to see you," said Hermione.

Harry nodded and briefly repeated the conversation to them. Hermione frowned after listening, "If Selwyn is so dangerous, we must find a way to control him."
