Hogwarts, this professor is too stable.

With the creaking of the door opening, five people entered the room at the end of the corridor on the fourth floor.

If a new book "Hogwarts: A School History" is compiled, then this incident may also be included. You know, it can bring together the extracurricular activities of Gryffindor, Slytherin, and Ravenclaw students at the same time. , except for eating in the auditorium, there is really too little.

The barking of the dungeon immediately rang in their ears. Although Hagrid's big dog couldn't see them, all three of its noses were twitching and sniffing crazily in their direction.

"What's that thing at its feet?" Hermione asked quietly.

"Looks like a harp," said Ron. "Snape must have left it."

"Apparently as soon as the music stops, it wakes up immediately."

Daphne chuckled and added: "Ronald, please add the prefix professor when calling the dean of our college, even if we are here to expose his conspiracy, hehe."

Is this woman sick?

Ron turned his head to the side speechlessly, not wanting to pay attention.

"Okay, listen..." Harry put the disciple Hagrid gave him to his mouth and started to play, but the big dog obviously didn't want to pay much attention to his music, which was squeaky and squeaky. The sound, to say it was noise, was just flattering Harry, and it didn't have the feeling that a musical note should have at all.

Daphne couldn't stand it anymore, so she took the flute from Harry's hand and gently put it to her mouth. The melodious and gentle music soon filled the whole room.

The big dog's eyes sunk as the notes beat, and its six ears drooped.

Slowly, its barking stopped - it swayed, its knees softened and it knelt down, then flopped down on the floor and fell into a deep sleep.

"Keep blowing, don't stop," Hermione reminded Daphne.

At the same time, they tiptoed towards the trap door.

"Won't she follow?" Ron asked, pointing to Daphne who was standing by the door and playing the flute non-stop.

The big dog pounced, and its smelly, hot head seemed to sense something, and Hermione quickly covered Ron's mouth.

After hearing Ron's words, Harry was also very anxious now. Daphne wouldn't go to the professor or Filch to complain, right? Is this to lock a few of us inside a dog? Without musical instruments, no one can get out?

He couldn't help but think otherwise. It was actually caused by Draco Malfoy before. Once bitten by a snake, he was afraid of ropes for ten years.

Draco's snake wasn't exactly venomous, but it was quite disgusting.

……

At this time, in the principal's office, Professor Snape's face was so gloomy that he was about to shed tears.

"Dumbledore, how many points will she be deducted?" he asked succinctly.

Dumbledore was enjoying the wonderful sound of the flute and seemed to be intoxicated by it. As expected, he was indeed a eldest lady from a noble family. She really knew everything.

His thoughts were interrupted by Snape's words, and Dumbledore was not angry, "No points will be deducted, Severus. This young lady from the Greengrass family played a beautiful piece of music. After Harry... Potter played an important role in preventing Professor Kettleburn from stealing the Philosopher's Stone, for which Slytherin can add 50 points."

Professor Snape was stunned, and he soon realized what was going to happen next.

Yes, there were three Gryffindors...

Doesn't that mean that Snape was counting the house points over and over in his mind, and it seemed that Gryffindor couldn't compare to Slytherin even with 150 more points.

You know, now that the semester is over, he has no chance to add points to Slytherin and subtract points to Gryffindor.

The College Cup is related to the enrollment situation in the second year. Slytherin, which has won the College Cup for many years, has recruited many outstanding young wizards from Muggle families in recent years.

Although Snape didn't care about this, Gryffindor won the House Cup because Harry Potter was surpassed by another savior act, which made him very uncomfortable!

Mochir on the other side was not thinking about these nonsense things. What he saw was completely different from Snape.

Mochir is still sighing with Eve: "Hermione is worthy of being the woman who will become the Minister of Magic in the future. She is indeed a natural politician."

What is a born politician?

There is no answer to this, but Mochier feels that this kind of person needs to have at least two minimum qualities, the ability to identify outstanding talents, and the ability to combine the strengths of all parties (leadership).

Just like Liu Bang and Zhu Yuanzhang in the East, if you can do these two things, you will not be too bad no matter how you mix.

Sigh... If this continues, when will we find a suitable research assistant?

Moqier feels that his requirements are not high!

Eve, who was reading a book crazily, didn't know that her master was watching the live broadcast, so she pretended not to hear and continued to work hard.

It was clear that Eve had inherited Mochiel's thirst for knowledge and Ravenclaw spirit.

Devil's Web - Door Key - Wizard Chess - Finally, the part Moqil was looking forward to finally came, the room that belonged to him. Moqil wanted to see how these children understood time.

Don't underestimate these first-year wizards. Sometimes a ridiculously naive point of view can promote huge development in the subject.

However, when Harry, Hermione, and Qiu pushed open the wooden door, almost everyone opened their eyes in disbelief.

I saw a pile of papyrus slowly stacked on the ground, full of formulas written on it.

Moqil rubbed his eyes. He could not clearly see what was written on the papyrus, but judging from the exchange in the tavern that day, Moqil did not feel that this should be the correct answer.

Zeno studied numerous paradoxes in order to do one thing: to disprove the continuity of time and space. In this process, many famous paradoxes were raised, such as the "Zeno's tortoise" problem and the "flying arrow motionless" problem, which are the more famous ones. Among them, "Zeno's Tortoise" tells the story of Achilles chasing a tortoise:

Achilles is a hero in ancient Greek legend). He is famous for his fast speed and his whole body is invulnerable. Only his heel is his shield, and he later died because of it.

Once, Achilles met a turtle. The tortoise said to Achilles: "Although you run fast, you can never catch up with me." Achilles was surprised and asked the tortoise: "Why?" The tortoise said: "Because I am in front of you. Suppose our distance is 1000 meters, your speed is 10 meters/second, and my speed is 1 meter/second. If you want to catch up with me, there are several stages."

1. It takes you 1000 seconds to run 100 meters. During this time, I walked forward 100 meters and I am still in front of you.

2. It took you another 100 seconds to run the remaining 10 meters. During this time, I ran another 10 meters.

3. You continued to chase for 10 meters, it took 1 second, and I ran another 1 meter.

According to the tortoise, the distance between them will only keep getting smaller, but it will never become 0, so Achilles can never catch up with the tortoise. But we know that this is not the case. Achilles can catch up with the tortoise, but we can't tell why. So where is the problem?

The turtle said: Follow this process to catch up, I will always be in front of you. Although the distance between us is getting closer and closer, there is always a small distance. Therefore, Achilles, you will never catch up with me.

What Moqi'er didn't expect was that Qiu actually chose a different way to pass the test.

Qiu, who went in and out of the Ravenclaw common room every day, didn't take long to let the knocker open the door obediently.

Yes, the door knocker made by Ravenclaw really doesn't have much moral integrity.

When you can't answer a question, you can ask another question that the knocker can't answer, and the knocker will also let you in!

This is the bug left by Ravenclaw.

But who is to blame?

Mochir is speechless in emo. Is it because he always answered the knocker's question when he was in school? Or is it because there are no Ravenclaws among the Death Eaters?
