Hogwarts: The Savior's Strong Cousin

Harry nodded solemnly, feeling both excited and nervous.

From that day on, Harry began his special magic training. He spent a lot of time in the library looking up information about the spell of space travel, and Hermione also tried her best to help him find relevant books and scrolls. Although Ron didn't quite understand, he also supported Harry from the side.

One night, Harry found an ancient magic book in a corner of the library, with "The Secret of the Spell of Shuttle Universe" written on the cover. He opened it carefully, and the pages made a rustling sound, as if whispering.

"Harry, this book looks very special," Hermione whispered. "It seems to contain a lot of details about this spell."

"Yes, Hermione," Harry responded, "I think this book will help us solve a lot of mysteries."

They read together, and the book described many theories and practical methods of traveling through the universe. Harry gradually understood the core principles of this spell, but the actual operation was difficult.

Finally, on a dark and windy night, Harry decided to make his first attempt. He stood on the astronomy tower of Hogwarts, holding the wand tightly in both hands, and silently chanted the spell in his heart.

"Harry, remember to focus," Hermione reminded beside him, a hint of worry in her voice.

"I know, Hermione," Harry took a deep breath and closed his eyes, focusing on the spell in his head.

Suddenly, Harry felt a strong force gushing out of the wand and surrounding his body. His eyes went dark, and then he felt himself being pulled into a spinning vortex. When he opened his eyes again, he found himself in a completely unfamiliar place.

This world was completely different from Hogwarts, with huge islands floating in the sky and strange lights flickering around. Harry couldn't help but marvel at the magical atmosphere of this place.

"Where is this?" Harry muttered to himself, trying to comprehend where he was.

Just then, a wizard in strange robes appeared in front of him, smiled at Harry and said, "Welcome, young wizard. You have successfully traveled across the universe."

Harry felt a mixture of surprise, excitement, and nervousness. He responded politely, "Thank you. I'm Harry Potter."

The wizard nodded and said, "I know who you are. You have an extraordinary talent and are able to master this ancient and powerful spell. Next, you need to learn how to travel through different universes and understand their laws."

In the following days, Harry followed the wizard to learn how to control and use spells to travel through the universe. They traveled through countless strange worlds, some of which were highly technologically advanced, and some of which were full of magic. Harry learned many new magic skills and saw various civilizations and creatures.

Whenever he returned to Hogwarts, Harry would share his experiences with Ron and Hermione, and the three of them would often talk about these wonderful adventures in the common room of Gryffindor Tower.

"Harry, you're amazing!" Ron always exclaimed, "You can actually travel through different universes!"

"However, this also means more responsibilities and challenges," Hermione seemed more cautious. "Harry, you have to be careful of the unknown dangers."

Harry nodded. He knew Hermione was right. This experience not only allowed him to see more of the world, but also made him understand more truths. He had to learn to be more cautious and wise so that he could be at ease in future adventures.

As Harry mastered the spell of traveling through the universe, he found that his talent in magic was becoming more and more outstanding, and the courses at Hogwarts became easier. He began to help other students answer questions and became a role model in everyone's mind.

Harry continued to grow in his studies and adventures at Hogwarts, and his spell of traveling through the universe became more and more proficient. One night, he, Ron, and Hermione decided to try this spell together to explore a new world.

"Harry, are you sure we can all do this?" Ron asked nervously, his hand shaking slightly around his wand.

"Don't worry, Ron, I've practiced this plenty of times," Harry reassured him, "as long as we stay focused, there will be no problem."

"Hermione, have you mastered the basic spells?" Harry asked.

Hermione nodded, her eyes firm, "Yes, Harry. I'm ready."

Harry looked at his friends, took a deep breath, and said, "Okay, let's get started."

They stood on the top of the Hogwarts Astronomy Tower, the three of them held hands and silently chanted spells in their hearts. As the wands glowed, they felt a strong energy surrounding them. Suddenly, the scene in front of them became blurred and the surroundings began to spin.

When they opened their eyes, they found themselves in a strange forest, where the trees towered into the sky, the leaves shone with a pale blue light, and the air was filled with a faint scent of flowers.

"This place is incredible!" Ron exclaimed, his eyes wide and full of curiosity.

"Indeed, the magical energy here is very strong," Hermione nodded in agreement, her eyes looking around, "but we have to be careful, I don't know if there is any danger here."

Harry also felt a surge of excitement, but he knew he had to remain vigilant. They began to explore the forest, moving forward cautiously.

Suddenly, a strange sound came from not far away, and the three quickly hid behind a big tree. Through the leaves, they saw a group of strange creatures wandering in the forest. These creatures were tall and thin, covered with silver scales, and their eyes emitted a faint blue light.

"What are those things?" Ron asked in a low voice, with a hint of fear in his voice.

"I don't know, but they look dangerous," Harry whispered back, "We'd better avoid them."

They held their breath, waiting for the group of creatures to go away. Just as they were about to move forward, Hermione suddenly frowned: "Wait a minute, I feel that the magical energy here is becoming unstable."

Harry and Ron also felt it. The air around them seemed to begin to tremble and the ground shook slightly.

"We have to get out of here now!" Harry said urgently. They stood in a circle again and tried to activate the teleportation spell.

But at this moment, something strange happened. The magical energy suddenly became violent, and their bodies were torn apart by a powerful force. Harry felt dizzy and the scene in front of him kept changing. He tried his best to concentrate, and finally, at the last moment, they were pulled back to Hogwarts.
