Hogwarts: The Savior's Strong Cousin

Harry nodded, "Professor, I will do my best to find Professor Snape and uncover the conspiracy of the dark magic forces."

In the next few days, Harry, Hermione and Ron continued to look for clues about Snape. They consulted a lot of materials and asked many professors and students, trying to find any possible information.

One night, Harry found an ancient diary in a corner of the library. This diary obviously belonged to a follower of the dark arts, and it recorded some important information about the rituals and plans of the dark arts.

"Harry, look at this," Hermione said excitedly, pointing to a passage in the diary. "It mentions a secret meeting place, which may be the headquarters of the Dark Arts."

Harry felt a surge of excitement in his heart, "We must go to that place, find their headquarters, and uncover their conspiracy."

Ron nodded, his eyes gleaming with determination. "We'll go together, Harry. No matter how dangerous it is, we'll face it together."

"What are these?" Harry asked, pointing at the boxes.

The strange wizard smiled and replied, "These are magic waters, each with different effects. There are some that can enhance magic power, some that can heal wounds, and some rare mixed waters that can improve mental concentration."

Harry's interest was piqued, especially the magical water that improved mental concentration. He decided to buy some and try it out, perhaps the water could help him better understand the mystery of strange energy.

"I want some magic water to improve my concentration," said Harry.

The wizard handed Harry several bottles of blue magic water and attached a sheet of instructions. Harry paid and returned to the table with the magic water. Hermione looked at the bottle in his hand and frowned: "Harry, do you really think this water is useful?"

Harry nodded. "Maybe. I just wanted to try. Anything that can calm my thoughts is worth a try right now."

That night, Harry returned to his dormitory and opened a bottle of blue magic water. He took a sip according to the instructions and immediately felt a refreshing feeling spreading from his throat to his whole body. His mind became clearer, and everything in front of him seemed to become more vivid. He began to organize his notes on strange energy.

Soon after, Harry found himself in a strange state. New ideas and thoughts kept emerging in his mind, and he seemed to be able to better understand those ancient magical texts. He felt an unprecedented calmness and concentration, as if he had found a bridge to communicate with strange energy.

Over the next few days, Harry continued to drink the magic water, and each time he could feel the spiritual uplift. He began to dream frequently about the core of the strange energy, and the crystal became brighter in his dreams, as if it was conveying some kind of message to him. Perhaps this power is not only a dangerous existence, it may also hide the answer to the problems of the wizarding world. Harry dreamed that he was standing in a huge magic library, with countless ancient books lined up on the bookshelves. He walked to one of the books, and what he saw after opening it shocked him. The book detailed the origin and use of strange energy, and even had instructions on how to safely harness this power.

After waking up, Harry eagerly recorded the contents of his dream. He knew it could be an important breakthrough, but he also realized that this path was full of unknown risks. He showed his notes to Hermione and Ron, and both were shocked by what Harry found.

"Harry, if this is all true, then we may be able to find a way to control strange energy," said Hermione, her eyes shining with excitement.

Ron seemed a little worried: "But Harry, this is too dangerous. If we fail, the consequences will be disastrous."

Harry nodded, feeling mixed emotions. He knew it was a dangerous path, but his curiosity and sense of responsibility kept him from retreating. He decided to continue his research and find a way to harness strange energy without causing destruction.

In order to learn more about strange energy, Harry decided to visit an old friend, Luna Lovegood. Luna has a unique insight into strange things, and maybe she can provide some help. So Harry, Hermione and Ron went to Luna's residence together.

"Harry! Long time no see!" Luna smiled brightly when she saw them. Her home was still filled with all kinds of strange decorations, and there were strange paintings hanging on the walls.

"Luna, we need your help." Harry said straight to the point and told her about the strange energy.

After listening to this, Luna showed a thoughtful expression on her face: "Strange energy, it sounds very interesting. I think I may have some books that can help you." She turned around, took out a few thick books from the bookshelf and handed them to Harry.

Harry opened one of the books and found that it contained a lot of knowledge about ancient magic and energy. He looked at Luna gratefully: "Thank you, Luna, these books are very helpful to us."

Luna smiled and said, "You're welcome, Harry. Remember, no matter what difficulties you encounter, keeping your inner peace and determination is the most important thing."

While studying strange energy, Harry found a clue about energy weapons. This weapon can concentrate and guide strange energy to protect oneself or fight against powerful enemies. Harry felt that he might need this weapon to fight potential dangers, so he decided to go to Diagon Alley to find an energy gun.

One weekend, Harry, Hermione and Ron went to Diagon Alley together. Walking on the familiar streets, Harry was full of tension and anticipation. He knew that this weapon might bring new challenges, but he firmly believed that this was necessary preparation.

They walked into a secret magic supply store, which displayed all kinds of strange magic props. A thin old wizard stood behind the counter, looking at them with sharp eyes.

"Is there anything you need?" the old wizard asked coldly.

Harry took a step forward and said in a low voice, "I heard you have energy weapons here."

The old wizard smiled slightly, with a sly look in his eyes: "You mean the energy gun? This kind of thing is not something that ordinary people can control. He said firmly: "I know its danger, but I need it to deal with greater threats."

The old wizard looked at Harry carefully, as if assessing his determination and ability. Finally, he turned around and took out a box from the cabinet behind the counter. He opened the box and found an exquisite energy gun lying quietly inside. The gun was engraved with complex runes and emitted a faint light.
