Hogwarts: The Savior's Strong Cousin

A few days passed, and Hogwarts returned to peace, but Harry's heart was still turbulent. Although the shadow of Cyrus Knox was temporarily dispelled, Harry always felt that things were far from over. Professor Snape's injury also made him feel guilty and powerless. Harry kept thinking, trying to find deeper clues.

One night, Harry sat alone by the window of Gryffindor Tower, looking at the starry sky outside, his heart filled with anxiety and uneasiness. He knew that there was someone who might be able to give him the answer, and that was Dumbledore. Although Dumbledore was no longer alive, his portrait was still hanging in the headmaster's office. Harry decided to find Dumbledore's portrait and ask for his guidance.

Harry whispered to himself, "I must go to Dumbledore, maybe he can give me some inspiration."

He quickly put on his coat, quietly left the dormitory, and walked towards the headmaster's office. Hogwarts was particularly quiet at night, with only Harry's footsteps echoing in the corridor. He walked to the door of the headmaster's office, gently opened the door, and walked in.

Dumbledore's portrait hung on the wall, still with that warm smile. Harry stood in front of the portrait, took a deep breath, and whispered, "Professor Dumbledore, I need your help."

Dumbledore's portrait smiled and said, "Harry, I have been keeping an eye on you. It seems you have encountered new difficulties."

Harry nodded, his eyes full of anxiety and doubt: "Professor, although we have temporarily stopped Cyrus Knox, I feel that things are far from over. I don't know what to do next."

Dumbledore's eyes became deep. "Harry, you did a great job. You and your friends have shown great courage and wisdom. But Cyrus Knox is indeed not an easy enemy to deal with. His power comes from an ancient and powerful dark magic. Only by finding his true weakness can we defeat him completely."

Harry frowned. "What's his weakness? We've tried so many things but he always manages to get away with it."

Dumbledore nodded slightly: "Cyrus' power comes from his contract with the dark forces. To break this contract, you need to find the source of his magic and destroy it. But this is not easy, you need more power and wisdom."

Harry felt powerless: "I don't know if we have enough power, Professor."

Dumbledore's portrait smiled and said, "Harry, you are stronger than you think. Remember, you are not alone. You have the support of Hermione and Ron, as well as other friends. Unity is your greatest strength."

Harry nodded, feeling a sense of warmth and determination. "Thank you, Professor. I will continue to work hard to find the source of Cyrus' magic."

After leaving the headmaster's office, Harry felt relieved. He decided to tell Hermione and Ron the information immediately. When he returned to Gryffindor Tower, he saw Hermione and Ron were still waiting for him, their faces full of concern.

"Harry, where have you been?" Hermione asked worriedly.

Harry sat down and told them about his conversation with Dumbledore's portrait. Hermione's eyes sparkled with wisdom after hearing this: "The source of Cyrus's magic? This is indeed an important clue."

Ron also seemed excited: "Then let's find the source of his magic and destroy it."

Harry nodded, "Yes, we must act quickly. But first, we need more information. Hermione, can you check the ancient records of Hogwarts to see if there are any clues about this dark magic?"

Hermione immediately agreed: "Of course, I will find it as soon as possible."

In the next few days, Hermione read a lot of ancient books and records in the library, and finally found some clues about Cyrus Knox and his magical source. She found a description of the "Shadow Stone" in an ancient magic book. This stone is said to be the source of the power of black magic.

"Harry, I found some clues," Hermione said excitedly, "It mentions something called the 'Shadow Stone', which may be the source of Cyrus' magic."

Harry looked at the description in the book and a new hope ignited in his heart: "We must find this stone and destroy it."

Ron frowned: "But where is this stone? How do we find it?"

Hermione pointed to a passage in the book: "It mentions here that the stone is hidden in an ancient underground maze and can only be found through a series of complex magical tests."

Harry said firmly, "Then we will go find this underground maze and face those tests. We must stop Cyrus."

The three began to prepare to set off, bringing all the necessary magic tools and protective equipment. They knew that this would be a difficult and dangerous adventure, but in order to protect Hogwarts, they had to move forward bravely.

After several days of searching and exploring, Harry, Hermione and Ron finally found the entrance to the underground maze in a hidden corner of Hogwarts. They took a deep breath, encouraged each other, and then embarked on an unknown road into the darkness.

The underground maze is full of dangers and traps, and they must move forward carefully. Along the way, they encountered many ancient magic tests that can only be successfully passed through through teamwork and wisdom. Harry felt that his bond with his friends became stronger, and in every danger, they were able to support each other and overcome difficulties.

Finally, at the deepest part of the maze, they saw the Shadow Stone. It emitted a dark light, as if attracting them to come closer. Harry clenched his wand and felt a strong pressure, but he knew that he had to destroy the stone to completely defeat Cyrus.

"Let's do it together," Harry whispered, a determined gleam in his eyes.

Hermione and Ron nodded, and the three of them raised their wands and chanted a powerful destructive spell: "Confringo!"

A strong light shot towards the Shadow Stone, and the stone began to vibrate violently, and then exploded with a loud bang. The power of darkness dissipated, and the entire maze seemed to be freed from the curse and returned to peace.

Harry felt a sense of relief, knowing that the source of Cyrus Knox's power had been destroyed and their mission was accomplished. They hugged each other and celebrated the victory, but also understood that the future was still full of challenges and unknowns.

After the Shadow Stone is destroyed, Harry, Hermione, and Ron return to Hogwarts, believing the threat of Cyrus Knox to be over, but Harry still has an uneasy feeling in his stomach. He can't shake the feeling that something is unresolved.
