Hogwarts: The Savior's Strong Cousin

They decided to go to the ancient castle immediately for a secret reconnaissance. As night fell, Harry, Hermione and Ron quietly left Hogwarts and headed towards the castle.

The castle looked particularly gloomy in the moonlight, surrounded by dense forests, and the air was filled with a mysterious and dangerous atmosphere. Harry felt the power in his heart surging, and he knew that this action was very important.

"We have to be careful," Hermione whispered. "We can't be spotted by them."

They approached the castle cautiously, using magical invisibility and protection spells to avoid making any noise. Harry felt his heart beating faster, and his heart was filled with determination and courage.

After entering the castle, they found it empty and unsettlingly quiet. Harry clenched his wand and prayed that they could complete the mission successfully.

"We must find Regulus's room," Harry whispered, "He must be hiding in there."

They searched all the way and finally found an ancient room deep in the castle. The door was engraved with complex runes, which was obviously some kind of powerful protective spell.

"This must be his room," said Hermione, taking out her wand and beginning to decipher the runes.

At this moment, a strong energy wave came, and Harry felt the power in his body surge again, as if foreshadowing the impending danger.

"Harry, look out!" Hermione called out, quickly casting a protective spell that enveloped them in a blanket of light.

The door of the room suddenly opened, and Regulus stood at the door with a cold light in his eyes. "How dare you break into my territory? You are really courting death!"

Harry felt the rage burning within him, and he concentrated his energy, preparing for a decisive battle with this powerful dark wizard. Regulus was clearly very powerful, but Harry knew that they could not back down.

"We're here to stop you," Harry said coldly, pointing his wand directly at the other man, "and you won't hurt anyone again."

The battle broke out instantly, magic beams intertwined in the air, and the flickering light illuminated the entire room. Harry felt the power in his body surging, and he concentrated his mind and released powerful spells, engaging in a fierce duel with Regulus.

Hermione and Ron were not to be outdone, they worked in perfect harmony, resisting each other's attacks while looking for opportunities to counterattack. Hermione recited a powerful binding spell, temporarily trapping Regulus, but the other party quickly broke free, swung his hand back, and released a black magic beam.

Harry was unable to dodge and was hit by the beam, feeling a sharp pain. He gritted his teeth, endured the pain, and stood firm again. He knew that this battle was not only for himself, but also for all those who were threatened by the dark magic organization.

"Harry, we can't give up!" Hermione shouted, with a determined gleam in her eyes.

"We will win," Ron added, his eyes full of fighting fire.

Harry felt the power within him growing stronger and stronger, and he gathered all his strength and released a powerful spell, hitting Regulus' chest directly. Regulus was knocked back, and a flash of pain and anger flashed across his face.

"You won't succeed!" Regulus roared, releasing another powerful attack spell.

Harry and Hermione quickly fought back, their magic beams intertwined with Regulus's beams in the air, forming a fierce energy collision. Harry felt

Harry, Hermione and Ron finally defeated Regulus, and the whole room fell into silence. Harry gasped, feeling the power in his body gradually subsiding. He looked at Regulus lying on the ground, and a complex emotion surged in his heart, including the joy of victory and the worry about the future.

"Harry, we did it," Hermione said softly, stepping forward with a gleam of relief in her eyes.

"Yes, but this is just the beginning," Harry replied, his eyes full of determination, "We must ensure the safety of Hogwarts and all its students."

Ron patted Harry's shoulder and said with a smile: "You are such a great wizard, Harry. We will definitely get through this crisis."

After returning to Hogwarts, Harry still felt uneasy. Although they defeated Regulus, the threat of the Dark Magic Organization still existed. Harry knew that they needed more power and resources to deal with future challenges.

One night, Harry was flipping through a book about ancient magic items in the library, trying to find some way to enhance their power. Suddenly, his eyes were attracted by a passage of text-"Crystal Source".

The crystal source is an ancient and powerful magic item that can enhance the magic power of wizards and provide extra protection. Harry feels that this is exactly what they need now, but obtaining the crystal source is not an easy task.

"Harry, what are you reading?" Hermione came over and saw the book in his hand and asked.

"I'm looking up information about crystal sources," Harry replied, a glimmer of hope in his eyes, "This kind of thing can enhance our magic power and can be very useful to us."

"But accessing crystal sources is very risky," Hermione said worriedly, "They are usually very well guarded."

"I know," Harry nodded, "but we need more forces to deal with the threat of the Dark Arts Organization. I think it's worth the risk."

Hermione was silent for a moment, then nodded in agreement. "Okay, let's go find the crystal source together, but we must be careful."

Harry decided to tell Ron about their plan. Ron's eyes flashed with surprise, but soon became firm. "I support you, Harry," he said, "Let's go find the crystal source together."

The next morning, the three decided to go to the place where the crystal source was said to be hidden - an ancient forest near Hogwarts. The forest was filled with a mysterious and dangerous atmosphere, and many legends and taboos revolved around this forest.

They walked through the dense woods and along an ancient path. Harry felt the tension and anticipation in his heart, and he knew that this operation was very important.

"We must find that hidden cave," Hermione said, carefully examining the map, "Legend has it that the source of the crystal is hidden deep within the cave."

After walking for several hours, they finally saw the cave hidden in the shadows of the trees. The entrance of the cave was covered by dense vines, and the air was filled with a mysterious atmosphere.

"Are you ready?" Harry asked in a low voice, holding his wand tightly and looking firmly at the entrance of the cave.

"Always ready," Hermione and Ron replied in unison.
