Hogwarts: The Savior's Strong Cousin

The new student's name was August Crowley, and he looked much calmer and more mature than the other new students. When Harry and his friends tried to talk to him, August always maintained a cold and distant attitude.

At the opening ceremony, the new headmaster of Hogwarts, Professor McGonagall, announced a major change: the school will hold an unprecedented magic competition called "Magic Clash". This competition is not only to improve students' magic skills, but also to strengthen their ability to face unknown challenges. The competition will be divided into two parts: individual competition and team competition. Students can freely form teams to participate. The winner will receive an extremely precious magic item - the legendary "Magic Key".

Harry, Ron and Hermione decided to form a team without hesitation, knowing that this would be an excellent opportunity to improve their magical abilities and uncover some of the secrets hidden in Hogwarts. During the registration process, August's name appeared again, and he chose to compete alone, which aroused Harry's curiosity and vigilance.

The first game was held on a vast lawn beside the Black Lake. The content of the game was to capture an extremely fast magical creature - the silver-winged Pegasus. Each participating team had to show their cooperation ability and personal magic skills. After the game started, each team took action. Harry and his team quickly found the trace of Pegasus with tacit cooperation. However, August caught the Pegasus with incredible speed and accuracy, which shocked everyone.

As the competition progresses, Harry and his friends discover that August's magical abilities far exceed those of ordinary freshmen. He seems to have mastered an ancient and powerful magic. In one competition after another, Harry's curiosity gradually turns into worry. He vaguely feels that there is a huge secret behind August. At the same time, some strange events begin to occur in the school: banned books in the library spontaneously fly out of the bookshelves, magical creatures in the forbidden forest become abnormally irritable, and some students even hear whispers and crying at night.

In order to find out the truth about these abnormal phenomena, Harry and his friends decided to sneak into the Forbidden Forest at night to investigate. Deep in the Forbidden Forest, they met a huge, injured unicorn. The unicorn told them that its injury was caused by a powerful black magic, and the source of this magic was inside Hogwarts. The unicorn begged Harry and his friends to stop the spread of this black magic, otherwise the entire magical world would be in great crisis.

With the unicorn's warning, Harry and his friends began to pay closer attention to August's actions. They found that August often disappeared at night and appeared in some forgotten Hogwarts basements and secret passages. After many tracking and investigations, Harry finally revealed August's true identity: he was actually a descendant of an ancient magic family. This family passed down a forbidden black magic from generation to generation, and August's purpose was to obtain the "magic key" through "magic collision" and unlock a powerful black magic ritual that had been sealed for centuries.

In the final battle of the game, Harry and his friends faced off against August. This was not only a competition of magic, but also a duel between justice and darkness. The venue of the final battle was set in the abandoned basement of Hogwarts, which was once the altar of ancient magic rituals. In the fierce battle, Harry and his friends finally defeated August with courage and wisdom.

Harry stood in the courtyard of Hogwarts, looking up at the sky, his heart filled with mixed emotions. Night fell, the sky was full of twinkling stars, but his heart could not calm down. He thought of August's cold eyes and the powerful power he showed. This power not only made Harry feel threatened, but also made him feel an unprecedented sense of responsibility - to protect Hogwarts and his friends.

"Harry, what are you thinking about?" Hermione's voice brought him out of his thoughts.

Harry turned around and looked at Hermione and Ron. Their faces were also full of worry and fatigue. Ron's face even had a few scratches left by the battle, but the determination in his eyes was not diminished at all.

"I'm wondering what we should do next." Harry took a deep breath and continued, "August's power is far beyond our expectations. We must find out his true purpose."

"We already know that he wants the 'magic key', and he obviously won't give it up easily." Hermione frowned, "But the key is, we don't know what he will do next."

"Maybe we should go to the central tower," Harry said suddenly, with a hint of determination in his voice.

Ron and Hermione looked at each other, obviously they were a little surprised by this proposal. The central tower is one of the most mysterious places in Hogwarts. It is said that there are many ancient and powerful magic books and props hidden there, but no student has ever dared to set foot in it easily.

"The Central Tower?" Ron asked hesitantly, "You mean we should go there to look for clues?"

"Yes," Harry nodded, "I have a hunch that the answers we need may be hidden there. Perhaps there are records about August's family, or forbidden books on those ancient dark magics he used."

"Harry, I know you want to find the answer, but the central tower is not a simple place." There was a hint of worry in Hermione's voice, "The magical protection there is extremely strong, we need to be fully prepared."

Harry looked at them, his eyes showing a hint of determination, "We have faced so many dangers. This time, I don't want to back down. If the central tower has the answers we need, then we must go find them."

Ron and Hermione looked at each other and nodded. "We'll go with you, Harry," said Hermione.

When the night completely enveloped Hogwarts, Harry, Ron and Hermione quietly left the Gryffindor Tower and headed towards the central tower. Their hearts were filled with tension and expectation, and unknown challenges were waiting for them.

After passing through a series of quiet corridors, they finally arrived at the entrance of the central tower. The atmosphere here was more gloomy than other places, and the ancient stone walls were covered with moss, as if they had experienced countless years of baptism.

"We can't get in." Ron muttered quietly, "The protective magic here is no joke."

"We have to give it a try." Hermione took out her wand from her pocket and whispered a complicated spell. The stone door trembled slightly, but remained closed.

Harry also raised his wand and chanted a spell in his mind. The stone door began to emit a faint light, but it still did not open.
