Hogwarts: The Savior's Strong Cousin

"This is the energy gun you want. It can concentrate and guide strange energy." The old wizard said, "However, using it requires extremely high concentration and magic power, otherwise the consequences will be disastrous."

Harry felt a chill rising from the bottom of his heart, but he still said firmly: "I am willing to accept this challenge."

The old wizard nodded, handed the energy gun to Harry, and gave him a manual. Harry left the shop with the energy gun. Harry couldn't wait to study how to use the energy gun. He set up a small laboratory in his dormitory to test and practice. He found that this energy gun needed to be driven by strange energy, and this energy could only be released stably through high concentration and control.

During a practice session, Harry felt the powerful force of the energy gun. When he concentrated and directed the strange energy into the gun, a dazzling light shot out instantly, smashing the target to pieces. Harry was filled with excitement and satisfaction, and he knew that this energy gun would become his powerful weapon.

However, after each use of the energy gun, Harry would feel extremely tired and weak. He realized that using this weapon required not only powerful magic power, but also good physical strength and endurance. In order to enhance his physical strength, Harry began to conduct rigorous training every day, including running, magic practice and meditation.

One afternoon, Harry was doing running training in the playground. Hermione and Ron were watching from the sidelines, and they admired Harry's determination and perseverance.

"Harry, do you really believe that energy gun can help us?" Hermione asked with worry in her eyes.

Harry paused and wiped the sweat from his forehead. "I don't know if it can solve all the problems, but I must be prepared. The existence of strange energy is a huge threat, and we can't take it lightly."

Ron nodded. "You're right, Harry. We all support you. No matter what challenges lie ahead, we will face them together."

Harry looked at his friends with gratitude, and felt a warmth and strength in his heart. He knew that no matter how difficult the road ahead was, with their support, he would not be alone.

In the following weeks, Harry continued to practice using the energy gun while continuing to study the secrets of strange energy. He found that every time he used the energy gun, his understanding of strange energy would deepen a little. This progress made him more determined in his belief. Harry sat at the desk in the dormitory, holding the energy gun in his hand, thinking back to the experiences of the past few months. He felt that he was constantly growing, not only in strength, but also in wisdom and determination. He knew that the road ahead was still full of unknowns, but he was ready to face it.

Hermione and Ron walked into the dormitory. Seeing Harry in deep thought, Hermione whispered, "Harry, no matter what happens, we will be by your side." She smiled and said, "Thank you. With you here, I feel that everything is not so terrible."

Harry decided to use the upcoming vacation to go home and practice magic, so that he would have more time and space to explore the potential of the energy gun and the mystery of strange energy. He was both looking forward to and nervous about this period of time, looking forward to being able to conduct research freely, and nervous about the unknown challenges and potential dangers.

Returning home, Harry felt a long-lost peace. The room still retained the layout of his childhood, and every corner was full of memories. He sat on the bed, with a lot of thoughts in his mind, both expectations for the future and worries about the unknown. He knew that this return home was not only for rest, but also for preparing for future battles.

Harry set up a special practice area and placed the energy gun and various magic books neatly on the table. He began to conduct rigorous training every day, not only to improve his physical strength and magic power, but also to control the energy gun and study strange energy. In the study, Harry was concentrating on reading an ancient magic book, trying to find more clues about strange energy. The text in the book was obscure, but Harry did not give up and read every word carefully. He felt that he was getting closer to the truth step by step, and his heart was full of tension and expectation.

"Harry, what are you researching?" Hermione's voice came from the door. She and Ron came to visit Harry to see his recent progress.

Harry looked up and gave a tired smile: "I am studying an ancient energy channeling technique, hoping to better control the energy gun."

Hermione walked over to Harry and looked at the book on his desk: "This book looks complicated, but if we can find the right guidance method, we may be able to solve many problems."

Ron asked with concern: "Harry, how are you feeling? You seem very tired recently."

Harry sighed, "It's a bit tiring indeed, but I feel like I'm making progress. With every practice, I can control the energy gun better, and I can understand the strange energy more deeply."

Hermione nodded: "Don't forget, proper rest is also very important. Excessive fatigue will only make your condition worse."

Harry looked at Hermione and Ron gratefully, feeling warm in his heart: "Thank you for your concern, I will pay attention to it."

In the next few days, Harry continued his practice and began to try to apply strange energy to other magic. He found that strange energy could not only enhance the power of energy guns, but also enhance the effects of other magic. This discovery made him very excited, as if a whole new world had opened up.

One day, Harry decided to try a new magic. He wanted to see if he could combine strange energy with protective magic. Standing in the middle of the practice area, he concentrated and began to cast a protective spell. As he recited the spell, he felt the strange energy surge in his body and gradually merged into the magic.

A layer of light blue light surrounded Harry, forming a solid shield. He could feel that the shield was stronger and more stable than ever before. Harry was filled with joy and pride, knowing that he was making continuous progress and getting closer to the truth and solving the problem.

"Harry, this is amazing!" Ron exclaimed as he watched Harry cast the protective magic.

Hermione also nodded approvingly: "This proves the potential of strange energy. As long as we keep working hard, we will definitely find the final solution."

Harry felt an unprecedented strength and confidence. He knew that although the road ahead was still full of unknowns and challenges, with the support of his friends and his own efforts, they would be able to find the truth and protect the peace of the wizarding world. Harry's training and research became more and more in-depth, and he became more and more proficient in mastering strange energy.
