The wizard in Hogwarts is unscientific

"I'm fine, Professor McGonagall," Harry said quickly.

"Oh, come here, poor kid." Professor McGonagall hugged Harry, obviously distressed.

She took out her wand and pointed it at Harry, and the water on Harry's clothes was instantly wiped away. After thinking about it, Professor McGonagall helped Professor Leidy clean up the water on his clothes.

"Thank you, Professor McGonagall." Professor Leidy said obediently.

Although Professor Leidy was also a student of Professor McGonagall, Professor McGonagall didn't think he was cute at all.

"Go on, what happened next?" Professor McGonagall asked.

Professor Leidy shrugged and explained: "The man used the killing curse as soon as he met him..."

Hearing these words, even though he knew that Professor Leidy and Harry were both fine, Professor McGonagall still felt her heart being tugged.

Professor Leidy continued: "Harry and I jumped off the bridge and swam to the shore. As soon as we came out of the water, we met Mr. Collins and Miss Granger."

"Well... I have to say, they were sitting on a bench watching the sunset. I'm sorry, Mr. Collins, Miss Granger, Harry and I to ruin your date."

Andy spread his hands and said he didn't care.

Hermione's face turned slightly red and she quickly said, "Your safety is the most important thing."

"Lady!" Professor McGonagall was a little dissatisfied.

Professor Leidy blinked at Andy, and then continued: "The man in black robe also chased him out. Mr. Collins used the Patronus Charm to attract the other person's attention, and then defeated him with the Explosive Charm."

"He fell into the water. I went into the water and chased him for a while, but unfortunately, he used the portkey to escape."

Harry said quickly: "It's not your fault, Professor Leidy."

After listening to the whole story, Professor McGonagall's face turned completely serious.

Since Professor Leidy can think of an insider in the castle, Professor McGonagall can naturally think of it too.

"Professor Leidy, Harry, you have just entered the water. I think you'd better go to the school doctor's office to take a cup of cold medicine."

"Mr. Collins, Miss Granger, you two are also very brave, for which Ravenclaw will add fifty points."

After saying that, Professor McGonagall turned to look at Snape, "Severus, what do you think?"

Harry looked at Snape too.

Although there was no evidence, he suspected that the spy in the castle was Snape.

Snape looked at Harry with a sneer, which almost made Harry angry.

"The man in black robe dares to come to Hogwarts to cause trouble. He should know that Dumbledore is not in the castle at the moment."

Snape returned to his expressionless face and said slowly: "But only a few of us know about this."

"But there is another possibility..."

"If Dumbledore left Hogwarts to investigate a certain dark wizard group, then the other party may also know Dumbledore's whereabouts."

Harry was obviously furious when he heard this. He felt that this was Snape's excuse.

But Professor McGonagall obviously believed Snape's words.

The professors in the castle have been working together for more than ten years, and Professor McGonagall really doesn't want to suspect that there is a traitor in the castle.

"You're right, Severus!"

Professor McGonagall said in a deep voice: "What is Albus investigating and leading people to Hogwarts? The other party's target is Mr. Potter... Could it be the remnants of the Death Eaters?"

Professor Leidy said: "The man in black robes does look like a Death Eater."

"Okay! All that needs to be said has been said."

"Harry, it's time for us to go to the school infirmary to take medicine."

After saying that, Professor Leidy pushed Harry towards the school doctor's office.

"Professor Leidy..." Harry was a little unwilling.

Professor Leidy leaned into Harry's ear and whispered: "You are too impulsive, Harry. Before you have evidence, it is best not to talk nonsense or show hostility. That will only make your enemies wary."

"If you suspect something, then look for evidence secretly, and then give him a fatal blow!"

Seeing that Professor Leidy and Harry had walked away, Andy shrugged and said, "Professor, Hermione and I also went back to rest."

"Sleep well, Mr. Collins and Miss Granger." Professor McGonagall smiled and nodded.

"You too," Andy said.

"Professor McGonagall, Professor Snape, goodbye!" Hermione waved.

When passing Snape, Andy glanced at him specifically, and Snape happened to look over as well.

Then……

Snape used Legilimency on Andy.

Damn it!

Snape, an old man, doesn't have martial ethics... Bah! Don’t talk about magic!

Fortunately, Andy had used Occlumency to clear his brain beforehand, otherwise he would have fallen into Snape's trap.

Snape was stunned for a moment. He thought Andy was looking at him to convey some important information.

Snape nodded to Andy without any trace, and Snape turned his head as if nothing had happened.

Andy: "..."

…

All the way to the eighth floor, Hermione suddenly said: "Andy!"

After speaking, Hermione gestured to Andy with her eyes: She had something to say.

"Want to go to the astronomy tower to see the stars?"

Andy smiled and said: "Although it's a little early, we can wait a little longer."

"Today is Monday, and at this time... there will be astronomy class soon." Hermione said helplessly.

OK!

Andy spread his hands and said, "Then let's go to the Room of Requirement."

Since the condition for opening the Room of Requirement is 'a room where you can talk', when Andy and Hermione opened the door of the Room of Requirement, they saw a luxurious conference room.

"It looks pretty good." Andy commented.

"Andy!"

Hermione found a chair and sat down, and then said with a serious face: "Who do you think the man in black robe is?"

"Huh?" Andy was stunned, "Did you find anything?"

Hermione nodded, "If that person is also a Death Eater, it means Voldemort has gathered a lot of people."

Andy thought for a while and then asked: "What do you think Dumbledore and Snape's plan is? Or, what is their purpose?"

Because it had nothing to do with him, Andy had not considered this matter before.

Although it was helpless to be suddenly involved in trouble, fortunately there was Professor Leidy who could help take the blame. When Snape reported to Voldemort, he only mentioned Professor Lady.

Andy could pull away.

But just in case, and because Hermione asked, Andy still planned to analyze it carefully, at least to understand the cause and effect of the matter.

Without waiting for Hermione to answer, Andy continued: "In terms of purpose, Voldemort actually has only one purpose, and that is to be resurrected."

"But he didn't have the manpower and didn't want to give up Snape's professorship, so he asked Snape to attack Azkaban and release a Death Eater."

"So theoretically, Voldemort can't have too many people."
