"Stimulate potential?" Snape looked at Felix with an inquiring look, folding his arms, "What are you going to use it for?"

"I'm a security officer, I can't go out like this, it's too embarrassing."

Snape stared at him for a while, he asked softly: "Next time I go to Diagon Alley to buy herbs, I won't see your wanted poster, right?"

Felix rubbed his chin, "It's hard to say... Don't stare at me, okay, I'm kidding, the fact is that I studied magic too much," he explained seriously.

But Snape didn't believe it at all. The next second, a series of magic patterns appeared on Felix's face, and Snape looked at this scene in surprise.

"What kind of potion do you want?"

"Of course the best one, the kind that will allow me to fight with someone after drinking it." Felix said with a smile: "How about a 50% discount for the sake of me being your student?"

Snape frowned, "That kind of potion has a lot of side effects."

"I can accept it," Felix said seriously, "Severus, I need it."

After a moment of silence--

"Wait!" Snape waved his sleeves and said in a vicious manner.

"Thanks, professor." Felix waved with a smile behind him.

...

"Hermione Jane Granger!" Mr. Granger shouted loudly, looking at his daughter who was peeking in from outside the door.

"Oh, Dad..." Hermione came in from outside, and the other warriors and their families in the room watched this scene with interest. She moved in step by step, looking at Mrs. Granger as if for help.

Mrs. Granger waved her hand, with an expression of watching a good show. "I'm waiting for your explanation, too."

"How about, um," Hermione whispered tentatively, "I'll take you around the campus?"

Mr. and Mrs. Granger stared at her at the same time, and Hermione stammered to finish her words: "This is your first time here, you must be very curious about this place, right? I've made some preparations, you will definitely like it..."

"What do you mean by 'preparation'? Leave your parents alone for most of the day?"

"I have to take the exam." Hermione whispered to defend herself.

Mr. Granger looked furious, and Mrs. Granger looked at her teasingly, "How did I hear that warriors don't have to take the exam? It was your friend Harry who you have been 'helping' who told me this. You don't want to hide from us, do you?"

Hermione was speechless.

It took Hermione a long time to barely appease her parents. They first visited the castle and then walked around the Black Lake. On the way, they met Harry and Sirius. Sirius tried hard to chat with Mr. and Mrs. Granger, but the effect was not very good. They couldn't get a word in about Quidditch, duels, adventures and other topics.

When Sirius vividly described how he solved a giant monster, he was not met with admiring eyes and questions about details, but with a look of confusion and vigilance.

Before the atmosphere fell to freezing point, Sirius finally found a common topic.

"Don't worry, there will be no danger. Their group is the favorite to win! And there is a safety officer... Felix Hepp, you know him too? Met him at the Leaky Cauldron? Great! I know him very well..."

Harry felt very strange. When the adults were talking, Hermione kept staring at him angrily.

He quietly approached, "What's wrong?"

Hermione turned her head to the side and refused to talk to him.

...

"Knocked out three Unspeakables? So that person's target is actually the Department of Mysteries?" Fudge asked behind the desk.

"Yes, he stole all the hourglasses, and the energy of the crystal glass cover was mostly lost..." said the Auror in charge of the investigation. The three Unspeakables who were unfortunately knocked out stood silently behind the Auror, bowing their heads and not speaking.

Fudge turned the quill for a long time, and then he raised his head.

"What do you think that man's purpose is?" He looked at the three Silents. "Travel through time? Change history?"

"Mr. Minister, don't worry, he can't do anything." Sol Crocker said impatiently.

"Why?" Fudge stopped writing with his quill. "He took so many hourglasses... just hourglasses?"

"That's right!" Sol Crocker was very happy that he understood this. "That man only had hourglasses, not a complete time converter."

"What if he found a broken time converter from outside and repaired it--"

"Impossible, no one can do this! Every scrapped time converter has been repeatedly confirmed by the Silents and cannot be repaired at all. We have tried for hundreds of years but have not succeeded. Instead, the existing time converters are getting fewer and fewer... It is even more impossible for an outsider to do it."

Fudge looked at him suspiciously.

"It's true," Sol Crocker said more and more confidently. This is his professional field. "Another point is that the energy in the stolen hourglass is very low. I guess that person also realized this, so he risked staying for a whole night to replenish his energy--" "

So what?" Fudge asked impatiently.

"Of course it failed." Sol Crook spread his hands, "No one can learn this technology in one night. So the energy inside naturally lost..."

"But if the hourglasses can't be used, why did that person take them all away?" Fudge asked with his eyes as big as a cow.

"Mr. Minister, it's not my field to figure out the criminal's mind. I can only make a judgment based on my expertise." Sol Crook shrugged and said, "The only problem is that the security system of the Department of Mysteries is not good enough. It should be upgraded."

"Thank you, Crook," Fudge interrupted him, "I will consider it, but you have to understand that the department is short of funds now. If there are new donations, I will consider you first."

The office fell into silence.

After a long time, Fudge asked hesitantly, "Did you see what that person looked like?"

Bode and Sol Crook shook their heads. What they saw was Felix's appearance after using the Polyjuice Potion. The two looked at Fudge's expression a little strange now, fearing that he would suddenly take out his wand and hit them.

"What about you? You should have seen something. The time limit of the Polyjuice Potion must have passed at that time." Fudge asked dully.

The third Silent Man said awkwardly, "I was distracted. That person used a despicable trap..."

Fudge lowered his head and looked through his testimony. "A ball of fire falling from the sky, burning debris? Yes, it was indeed despicable enough."

"..." The Silent Man bowed his head and said nothing.

Fudge continued to look through the report, "When I bowed my head, I was attacked by someone. I only saw a pair of feet... a pair of feet?" He raised his head, "Do you remember what those feet looked like? What are the characteristics?"

The Silent Man shook his head, "Sorry, Mr. Minister, I can't remember clearly."

"I don't think so," Fudge smiled a little, "At least you can get a vague outline, right? For example, are the steps brisk, belonging to a young man?"

...

In the evening, the young wizards ate happily in the auditorium, waiting for the start of the third project.

"Fudge, you brought a little too many people today." Dumbledore said gently.

"I think it is necessary. The Ministry of Magic has just experienced an attack," Fudge whispered, "I must be prepared."

"Ah, that's it." Dumbledore said softly, with a regretful expression on his face.

"By the way," Fudge looked around, "Why didn't I see Professor Happ?"

"Maybe he was delayed by something?" Dumbledore said with a smile.

Fudge looked around. Everyone was eating. He wiped the sweat from his forehead, hesitated for a moment and finally made up his mind, "Dumbledore, I need to seek your help. According to the Aurors' investigation, the lone traveler is terribly powerful, even, not worse than the man who cannot even mention his name!"

Dumbledore showed a puzzled expression at the right time.

"Dumbledore, I know we have disputes on some issues-"

"Not disputes." Dumbledore said.

"You-what?" Fudge looked at him at a loss.

"That's not a dispute, Fudge," Dumbledore said patiently, "Your hesitation will make us lose a lot of time-" "

Okay! Dumbledore," Fudge said angrily, "That's a dispute. I have already made a concession and sent a team of Aurors to investigate the Albanian forest. There will be results soon. What I want to talk about now is another thing!"

He slammed the table, and the fork on the plate jumped around.

Several principals of other schools at the table looked over here in confusion, and Fudge made a hasty gesture of apology. After everyone turned their heads, he leaned closer again and whispered, "Dumbledore, what I'm going to discuss with you now is how to deal with a dangerous criminal who unscrupulously broke into the Department of Mysteries and stole the time-turner hourglass and the energy stored for decades. My God, what an evil thing to do!"

Dumbledore looked at him calmly, "Excuse me, Fudge, you don't look anxious at all."

"Of course I'm anxious! What if he wants to falsify history? What if he is on the side of the You-Know-Who? What if we remind him on the day when the You-Know-Who loses his power?" Fudge's anger was getting out of control again, "You should know what serious consequences will result!"

Dumbledore's expression became serious.

"That's it," Fudge wiped his sweat and continued, "So I want to ask for your help. Our goals are the same. I promise you that as long as the investigation team brings back strong evidence, I will issue a warning to the public."

Dumbledore was silent for a moment, "Do you have any clues?"

"Of course," Fudge was overjoyed and couldn't wait to say, "He stayed in the Ministry of Magic for a whole night, trying to steal energy... He must be exhausted, and he was also injured by the Aurors. It's a pity that we couldn't find his blood at the scene... In any case, this kind of injury can't be recovered in a short time, so I'm curious about Professor Hepp's situation. Of course, I don't doubt him, I'm just cooperating with the investigation-"

Dumbledore's expression became more and more serious. Fudge thought his plan had succeeded and was so happy that his eyebrows were flying. At this moment, a person walked in from outside the hall.

Fudge stared at the man. Felix had a ruddy face and was in high spirits. He didn't look injured at all. He even changed into a formal suit and pulled out a chair to sit in an empty seat not far from them.

Fudge's face flushed.

"It seems that Felix is ​​not the person you are looking for. He is in great shape. This dress reminds me of the ball half a year ago. If there was music, I have no doubt that he would be the most prominent one..." Dumbledore put his fingers together and looked at Fudge's face with interest.

"Maybe I am thinking wrongly, Dumbledore," Fudge said breathlessly, his eyes fixed on Felix, unwillingly said: "I need to confirm it again."

"My office welcomes you at any time, Fudge, but you'd better bring evidence next time." Dumbledore said, his eyes were also on Felix - unlike Fudge, his azure blue eyes were extremely deep.

"Time..." he whispered.

When the enchanted ceiling turned from blue to dark purple twilight, Dumbledore stood up beside the table and everyone quieted down.

"Ladies and gentlemen, in five minutes, I will invite everyone to the competition venue to watch the last event of the championship. Now please ask the warriors to leave with Mr. Bagman."
