Hogwarts: The Savior's Strong Cousin

Returning to his office, Harry carefully placed the precious items on the table. He knew that these items would greatly enhance their strength, but more importantly, their determination and courage.

Hermione and Ron came over quickly, their eyes sparkling with excitement when they saw those precious magical items.

"Harry, this is fantastic!" exclaimed Hermione. "These items will greatly enhance our powers."

"Yes, we will definitely succeed." Ron was also full of confidence.

Harry nodded, "Yes, we must give it our all. Now, we need to continue practicing and preparing to make sure every step is done correctly."

In the following days, Harry, Hermione and Ron practiced and prepared intensively every day. They constantly adjusted and optimized every detail to ensure that every step of the ceremony could be executed perfectly. Harry's ability to condense the magic fruit was also constantly improving. He felt that powerful force surging in his body, and his heart was full of determination and confidence.

On a sunny morning, Harry, Hermione and Ron stood on the tower of Hogwarts, overlooking the entire castle. The sun shone on them, warm and bright. They knew that the moment of the decisive battle was coming, and all their preparations and efforts would be verified at this moment.

As the day of the final battle draws closer, Harry, Hermione and Ron's preparations are gradually coming to an end. They practice and adjust intensively every day to ensure that they can perform the key ritual perfectly. However, they don't know that a bigger crisis is quietly approaching.

One gloomy afternoon, Harry, Hermione and Ron were discussing the final details in a secret room at Hogwarts. Suddenly, Harry felt a strange chill and an uneasy premonition rose in his heart.

"We have to be very careful," Harry whispered, "The dark forces may attack at any time, and we can't be careless."

Hermione nodded, her brows furrowed. "I feel the same way, Harry. We have to make sure every step is foolproof."

Ron looked at them, a hint of worry in his eyes, "Do you think we can succeed?"

"We must succeed," Harry said firmly, "This is our mission."

At this moment, the door of the room was suddenly pushed open, and a figure appeared at the door. It was Ginny Weasley, her face was pale, and her eyes were full of fear.

"Harry, someone betrayed us!" Ginny's voice trembled, as if filled with endless fear.

Harry, Hermione and Ron were immediately shocked. They quickly stood up and gathered around Ginny.

"Ginny, what happened?" Harry asked anxiously.

"I...I heard some Death Eaters plotting. They said there's an undercover agent among us who's been passing information to them," Ginny's voice was filled with uncontrollable fear. "I don't know who it is, but they seem to know our plan."

Harry felt a chill from behind, and a strong anger and uneasiness surged in his heart. He knew that the existence of the undercover agent would greatly threaten their plan, and they had to find the traitor as soon as possible.

"We must find the undercover," Harry said calmly, with a determined gleam in his eyes, "otherwise, all our efforts will be in vain."

Hermione took a deep breath and nodded, "We need to calm down and analyze every detail carefully. This undercover agent will definitely leave clues."

Ron clenched his fists, an angry look on his face, "We can't let this traitor ruin our plan."

They began to review everything that had happened recently, trying to find any suspicious signs. Harry's mind kept flashing every detail of the past few days, everyone's words, every action. He knew that finding this undercover would be the key to whether they could succeed.

"We need a plan," Hermione suggested, "one that will draw out the undercover."

Harry nodded, thinking quickly in his mind, "Perhaps we can set a trap, pretending that there is a new critical mission, and then observe who will leak this information."

"Good idea, Harry," Ron agreed, "We can identify the traitor this way."

They immediately took action, arranged a fake mission, and secretly observed everyone's movements. The whole process was tense and secretive, and everyone was cautious and did not dare to make any mistakes.

One night, Harry lay in bed, thinking back to the details of the day. He felt deeply tired and depressed, but the firmness and determination in his heart still supported him.

"We will find the traitor," Harry said to himself, "for Hogwarts, for everyone."

The next day, their trap began to take effect. Harry, Hermione and Ron closely monitored everyone's movements, especially those who usually behaved suspiciously. Finally, they found some abnormal signs.

One night, Harry and Hermione quietly followed a suspicious figure, it was a member they had always suspected - Theodore Nott. His behavior had always been strange, and he often disappeared alone in certain corners of Hogwarts.

"Harry, be careful," Hermione warned in a low voice, "We have to make sure we are not discovered."

They followed Theodore closely and saw him enter a secret basement. Harry and Hermione looked at each other, their hearts filled with tension and anticipation.

"We need to go in and take a look," Harry whispered, "We can't let him continue to pass information to the Death Eaters."

They tiptoed into the basement and saw Theodore conspiring with several Death Eaters. Their conversation was clearly heard by Harry and Hermione, confirming that Theodore was the undercover agent.

"Harry, we have to stop him," Hermione said firmly, determination shining in her eyes.

Harry nodded, and they moved quickly to subdue Theodore and bring him back to the Order of the Phoenix's secret base.

"How dare you betray us!" Theodore roared angrily, with vicious light flashing in his eyes.

"You betrayed us, Theodore," Harry said coldly, "You will pay for what you have done."

They quickly handed Theodore over to Professor McGonagall and informed the other members of the Order of the Phoenix of the details of the incident. The whole team was angry and disappointed with the betrayer, but they also knew that they must be more united to defeat the impending dark force.
