Hogwarts: The Savior's Strong Cousin

The wizard waved his wand gently, and an ancient and powerful magic spread in the air. Harry felt as if time had stopped flowing around him, and the ripples on the lake were still in mid-air. The wizard's voice was particularly clear in the silence.

"Time and space are not as simple as you see. They are the most profound areas in the magic world. Mastering them requires not only strength, but also wisdom and inner balance. You must understand that every time you travel through time and space, you will leave traces behind you, and these traces will affect your future destiny."

Harry stared at the wizard closely, listening carefully to his every word. He felt that every word the wizard said contained endless wisdom, and these words made his understanding of time and space more profound.

The wizard continued, "Where you are standing now is one of the intersections of time and space. Here, the rules of time and space become blurred, and you can feel the interweaving of the past and the future, but this power can easily make you lose your mind. You must be careful not to let yourself indulge in this power, otherwise you will never be able to return to your original world. His inner determination became stronger. He knew that he had taken an important step, and this step would determine the direction of his future.

The wizard's eyes softened, and he said slowly: "You can practice here, but remember, don't stay too long. Every minute and every second that passes will have an irreversible impact on your future timeline. When you feel you are ready, remember to return to your original time and continue your unfinished mission."

One day, while reading an ancient book in the library, Harry stumbled upon a description of ancient magic. The book mentioned a power called "strange energy", which could give wizards infinite power, but could also bring devastating consequences. Harry was attracted by this mysterious power and decided to study it in depth.

With the help of Hermione, Harry began to look up more information about strange energy. The two discovered that this energy had appeared once a few centuries ago and almost destroyed the entire magical world. In order to prevent this power from getting out of control again, the ancient wizards sealed it deep underground in Hogwarts and set up heavy magical protection.

Harry and Hermione realized that these protections might be gradually failing. At the same time, some strange phenomena began to appear in the school: the creatures in the forbidden forest became unusually active, the lake emitted a strange light, and even the walls of Hogwarts occasionally shook. All signs point to one conclusion: strange energy is awakening. Harry kept having strange dreams, in which he saw a mysterious tunnel leading deep underground. Every time he woke up, he could remember the details of the dream, as if these dreams were guiding him to find something. In the end, Harry decided to follow the guidance of the dream and personally explore the source of this strange energy.

Harry, Hermione and Ron decided to act together. They sneaked into the underground in the dead of night, passed through layers of magical obstacles, and finally came to the entrance of the tunnel in their dreams. The tunnel was bottomless, and the dim light danced on the walls, as if mocking their arrival.

After entering the tunnel, the three found that it was full of ancient and powerful magical power. Every step they took felt an invisible pressure approaching. After a long and difficult journey, they finally came to a huge underground cave. In the center of the cave, a glowing crystal was suspended, which was the core of the strange energy.

Just as they were about to explore further, a powerful force suddenly erupted, knocking the three back several steps. A figure appeared in the cave. It was an ancient wizard wearing tattered robes, with fanatical light flashing in his eyes. He claimed to be the guardian of strange energy and had been waiting for someone who could harness this power for hundreds of years.

The guardian told Harry that strange energy can not only give wizards powerful powers, but also reveal the mysteries of the universe. However, harnessing this power requires great courage and wisdom, otherwise it will be swallowed up. Harry faces a difficult choice: whether to try to harness this power and save the magical world, or to seal it again and let it sleep forever.

As Harry was thinking, a huge force surged out of the crystal and enveloped him. Harry felt his consciousness gradually blurred, as if he had entered another dimension. In this strange space, he saw the past and the future, and witnessed the origin and possible end of the magic world. He felt an unprecedented power surging in his body, as if the energy of the entire universe was converging on him.

Just when Harry was about to be swallowed by the power, a warm light suddenly appeared, pulling him back to reality from the darkness. It was Dumbledore's voice, whispering in Harry's ear, reminding him to keep his heart calm and firm. Harry finally woke up and found himself still standing in the cave, and the light of the crystal gradually dimmed.

Harry decided not to try to harness the strange energy, but to seal it again. He understood that the true meaning of power lies in how to use it, not in possession. The three of them worked together to cast an ancient sealing spell and sealed the strange energy deep underground again. The cave returned to peace, and the strange power disappeared.

After returning to the ground, although Harry decided not to try to control the strange energy, he still felt shocked. The existence of this power made him realize that the magical world was more complicated and dangerous than he understood. Despite sealing the strange energy, Harry's heart was still full of doubts and uneasiness. In order to comfort himself, he decided to go to Hogsmeade Village to relax.

One day, Harry, Hermione, and Ron were drinking butterbeer in the Three Broomsticks in Hogsmeade, trying to put their adventure behind them. Harry absentmindedly stirred his drink, thinking about the strange feeling of energy. Hermione noticed Harry's concern and whispered, "Harry, are you all right?"

Harry looked up, saw the concerned looks on his friends' faces, sighed and said, "I just think that the energy is too strong, sealing it is only a temporary solution. Are we really doing the right thing?"

Ron patted Harry's shoulder and comforted him, "Harry, we did what we could. That kind of power is too dangerous, and no one can control it easily."

Just then, the doorbell of the bar rang, and a strange wizard walked in. He was wearing a dark robe, carrying a box full of bottles in his hand, and walked straight to the bar counter. Harry noticed that the box contained magic water of various colors, and each bottle was labeled with complex runes. Curiosity drove him to step forward.
