Hogwarts: The Savior's Strong Cousin

"Okay, let's split up," Harry said, his eyes gleaming with determination. "Hermione, you'll be responsible for preparing the truth potion and the memory checking spell. Ron, you and I will set the trap and lead the undercover agent to reveal his true colors."

Professor McGonagall nodded and said, "I will arrange for other professors to assist you to ensure the smooth progress of the operation. Parvati, you can also help us and provide some clues you know."

Parvati looked at Harry gratefully and nodded firmly. "I am willing to help you and make up for my mistake."

In the next few days, Harry, Hermione and Ron began intensive preparations. Hermione consulted a lot of information in the library and prepared a bottle of powerful truth potion. Harry and Ron set up many traps and surveillance spells in every corner of Hogwarts, hoping to lead the undercover to reveal their flaws.

One night, Harry and Ron set up the last trap in a remote corner of Hogwarts. They placed a fake magic fruit message in a conspicuous place and set a powerful alarm spell that would be triggered immediately if someone touched it.

"Harry, do you think this plan will succeed?" Ron asked in a low voice with a hint of uneasiness in his eyes.

"I don't know, Ron, but it's the best we can think of right now," Harry replied, a determined glint in his eyes. "We have to believe in ourselves, and we have to believe in Parvati."

They returned to the common room where Hermione was waiting for them, holding the bottle of Truth Potion.

"Harry, Ron, the potion is ready," Hermione said, with a hint of nervousness in her tone. "We need to use it carefully to ensure that the suspect does not notice it."

Harry nodded, "We'll be careful, Hermione. Now we just have to wait and see who takes the bait."

While they were waiting, Parvati suddenly walked in, looking a little pale.

"Harry, I just heard some news that someone is planning an attack on our traps," Parvati whispered, a hint of nervousness in her voice.

Harry felt his heart tighten. "Parvati, what did you hear? Who is planning the attack?"

Parvati took a deep breath. "They are a few Slytherin students. They seem to know some of our plans. I am worried that they may be undercover agents of the dark magic forces."

Harry frowned, knowing that things were more complicated than they thought. "We must take action immediately and not let them succeed."

Harry, Hermione and Ron quickly went to the Slytherin common room to prepare for the raid. With the help of Professor McGonagall, they were able to successfully enter the Slytherin underground passage.

As they crept closer to the common room, they heard several people talking in low voices. Harry held his breath and motioned to Hermione and Ron to keep quiet.

"We must find the magic fruit before they do," said a familiar voice. It was Draco Malfoy, and there was a hint of nervousness and anxiety in his voice. "Otherwise our plan will fail."

Harry's heart tightened. Draco was indeed connected to the dark magic forces. They needed to act immediately to uncover the truth.

Hermione nodded slightly, motioning Harry to move on. They approached quietly, and Hermione took out the truth potion, ready to use it on Draco.

At this moment, Draco suddenly became alert, turned around, and saw Harry and others standing at the door. His face suddenly changed, and he quickly drew his wand and prepared to defend himself.

"What are you doing here?" Draco asked sharply, with a hint of fear in his eyes.

"Draco, we know you have connections to the Dark Arts," Harry said calmly, his wand clenched in his hand. "Now, it's time for you to explain."

Draco's face was pale, and he obviously didn't expect things to be exposed so quickly. His hands were shaking slightly, but he still tried to stay calm.

"I don't know what you're talking about, Potter," Draco said forcefully, but he couldn't hide the fear in his eyes.

Hermione quickly cast a binding spell to keep Draco in place. Then, she took out the truth potion and approached Draco.

"Drink it, Draco, and we'll find out the truth," Hermione said calmly.

Draco struggled for a while, but was eventually forced to drink the truth potion. After a moment, his eyes became blank, and he obviously could no longer control his words.

"Tell us, Draco, what are your connections to the Dark Arts?" Harry asked seriously.

Draco's voice became robotic and calm. "They threatened me that if I didn't help them, they would hurt my family. I had no choice."

Harry felt a surge of anger and helplessness. He knew Draco was also forced, but that didn't change what he had done. "Who are they, Draco? Tell us their plan."

Draco continued, "They plan to create chaos within Hogwarts, weaken the school's defenses, and eventually seize the magical fruit. Their leader is a powerful dark wizard who hides in the shadows and manipulates everything."

Harry nodded, feeling that things were becoming clearer. "Draco, we will protect your family, but you must fully cooperate with us to expose the truth about the dark forces."

Draco nodded blankly, with a mixed feeling in his eyes. He knew he had no choice but to cooperate with Harry and his friends.

Harry, Hermione and Ron took Draco back to Professor McGonagall's office and reported the incident in detail. "Harry, you did a great job," said Professor McGonagall, with a glimmer of approval in her eyes. "We must seize this opportunity to thoroughly expose the conspiracy of the dark magic forces."

Harry Potter has been feeling confused lately. Although they have successfully exposed Draco's connection with the dark magic forces, the real threat has not been eliminated. One morning, Harry received an urgent letter from Professor McGonagall in the Gryffindor common room. The letter briefly asked him to go to the dormitory immediately. Harry's heart tightened, knowing that something big must have happened.

Hurrying to the dormitory area, Harry found Professor McGonagall already waiting for him. Her expression looked extremely serious and nervous.

"Harry, we have a problem," Professor McGonagall said straight to the point. "Professor Snape has disappeared."

Harry felt a wave of shock and discomfort. Although his relationship with Snape had always been complicated, he knew Snape's importance in Hogwarts. "Professor, do you know where he was last seen?"

Professor McGonagall shook her head, her brow furrowed. "He was last seen in his office, but that was last night. No one has seen him since."
