Hogwarts: The Savior's Strong Cousin

Harry Potter's heart has been in turmoil for a long time since the conflict with Drake. He knows that he needs more strength and knowledge to face future challenges. One night, he, Hermione and Ron were discussing the recent situation in the common room, and Harry suddenly remembered the crystal source found in the forbidden forest.

"I think we need more knowledge about the crystal source," Harry said, his tone firm, "perhaps we can find a way to harness its power."

Hermione nodded in agreement, "Yes, Harry. That crystal apparently has powerful magical powers, and if we can use it correctly, it could be a powerful weapon against the Dark Arts."

Ron asked worriedly, "But, Harry, where can we find such a crystal source? Besides, this kind of thing is definitely not easy to control."

Harry thought for a moment, then said, "I've heard that there's a mysterious shop in Diagon Alley. It's said that there are all kinds of rare magical items there. Maybe we can go there and take a look."

The next morning, the three decided to go to Diagon Alley. They walked through Hogsmeade Village, came to the Three Broomsticks, and used Floo Powder to teleport to Diagon Alley. Harry, Hermione, and Ron quickly passed through the crowded crowd and found the mysterious shop - "The Mysterious Magic Item Shop".

The shop was hidden in a remote alley in Diagon Alley, with an old wooden sign on the door that read "Mysterious Magic Items Shop." They pushed open the creaking wooden door and walked into the dim shop.

The shop was filled with all kinds of ancient and strange magical items, and the air was filled with a mysterious aroma. A shopkeeper wearing a black hood came out from the corner and asked in a hoarse voice: "Welcome, what do you need?"

Harry stepped forward and said bluntly, "We are looking for a powerful magical crystal. Do you have anything like this here?"

The shopkeeper was silent for a moment, as if he was assessing their intentions. Then he nodded and motioned for them to follow him. Harry, Hermione, and Ron followed the shopkeeper through a narrow passage and into a small, dimly lit room. On the counter in the middle of the room sat a gleaming crystal.

"This is the crystal source you are looking for." The shop owner said, with a hint of mystery in his voice, "It has powerful magical energy, but you must use it with caution, otherwise it may bring unpredictable consequences."

Harry approached the counter and looked at the crystal carefully. He felt a strong wave of magic coming from the crystal, as if responding to his power. He knew that this was exactly what they needed.

"We want this crystal source." Harry said firmly.

The shopkeeper smiled, held out his hand and said, "It's expensive, but I'm sure you know its value."

Harry took out a bag of gold coins from his pocket and put it in the shopkeeper's hand. The shopkeeper nodded, indicating that they could take the crystal.

"Remember, use it with caution," the shopkeeper whispered, "Its power is a double-edged sword."

Harry, Hermione and Ron left the shop with the crystal source, full of anticipation and caution. After returning to Hogwarts, they immediately began to study how to use the crystal source correctly.

"We have to find a way to combine its power with our magic," Hermione said, flipping through an ancient spellbook. "This requires very fine control."

Harry nodded in agreement, "Yes, we can't take it lightly. Any mistake could lead to serious consequences."

Ron looked at the crystal and said, "But if we succeed, this crystal will become our most powerful weapon."

After a few days, they finally found a way to safely activate and use the energy of the crystal source. Harry decided to conduct the first test at the test site to make sure everything was under control.

"Is everyone ready?" Harry asked, holding the crystal source in his hand and feeling its energy trembling slightly.

Hermione and Ron nodded, each raising their wands, ready for any eventuality.

Harry took a deep breath, closed his eyes, and concentrated. He began to chant a spell, directing his magical power into the crystal source. The crystal began to emit a dazzling light, and a strong magical energy filled the air.

"Stay focused, Harry," Hermione whispered. She could feel the powerful energy.

Harry felt the energy of the crystal source gradually merge with his magical power, and he tried to control this power to ensure that it would not get out of control. Finally, the light of the crystal stabilized, and Harry felt a powerful force flowing in his body.

"We did it," Harry said with a smile, opening his eyes to see Hermione and Ron also smiling with relief.

"This is just the first step," Hermione said. "We still need more research to ensure that it can be used safely in actual combat."

Ron nodded. "Yes, but at least we know that the crystal is usable. Next, we have to make sure every detail is perfect."

Harry felt hope and strength fill his heart. He knew that with this crystal source, they would be more confident in facing the dark arts. They would continue to work hard, making sure that every step was taken steadily and firmly.

In the following days, Harry, Hermione and Ron continued to practice and gradually mastered how to merge with the power of the crystal source. Their tacit cooperation and joint efforts made them more powerful in the magical confrontation.

One night, Harry stood on the high tower of Hogwarts, looking at the night sky in the distance, his heart full of determination and expectation. He knew that there were many unknown challenges in the future, but with the support of this crystal source and his friends, he would be able to overcome all difficulties and protect the Hogwarts they loved.

In the process of mastering the crystal source, Harry Potter deeply realized the purity and importance of power. He became more and more aware that power is not only a tool to defeat the enemy, but also a responsibility and an ability to protect the people he loves. Whenever he looked at the glimmer of light from the crystal source, a firm belief would surge in his heart.

One evening, Harry was practicing alone in the test field, trying to control the energy of the crystal source more accurately. He closed his eyes, took a deep breath, and felt the flow of magic in his body. Every time he stimulated the power of the crystal source, he could feel the pure power surging in his body.

"Pure power means complete control over oneself." Harry thought to himself. He has always valued this kind of power. He knows that only by fully controlling his magic can he protect himself and his friends at critical moments.
