Defense Against the Dark Arts Professor at Hogwarts

Chris, who was left behind, muttered to himself, "What kind of gathering can we attend at night?"

......

On Friday morning, Chris walked into the Defense Against the Dark Arts classroom, a fifth-grade class.

"What are you looking forward to? Do you want me to show you some new tricks?" Chris asked, looking at the excited students below.

"Of course, teaching assistant. We heard your theory from the seventh grade, so we are all very interested." A Gryffindor student stood up excitedly.

"It's a pity that you are only in fifth grade. The most important thing for you now is to pass the OWL exam. If you don't achieve "beyond imagination", you won't be able to enroll in my improvement class. Of course, if I am still here next year. "

Chris looked at the student who sighed at the moment of disappointment and said with a smile:

"But I brought something different this time."

The interest of the teenagers increased again.

Chris took out a box and placed it on the table.

"Before I do this, I have something I want to know about. How many people have become Aurors after graduation?"

The wizards in the classroom looked at each other. Only three people raised their hands, and they were all from Gryffindor House.Chris was stunned for a moment, are there only such a few people?When he first came to the school for research, there were a large number of people who wanted to serve as Aurors.

Then he thought of something and changed his words:

"How many people want to be Aurors before I teach seventh years?"

At this time, a dozen people raised their hands hesitantly.

Is this normal?

And Chris suddenly discovered that the three little lions who raised their hands at the beginning actually put their hands down!

Well, as expected of Gryffindor!

Outrageous.

Chris motioned for everyone to put their hands down, pointed at the box and said:

"Then what I will tell you in this lesson is a real accident that I encountered in my Auror career, which almost led to the annihilation of twelve Aurors!"

As he spoke, he opened the box and took out a flowerpot inside. There was a green and purple seedling planted in the flowerpot.

"Does anyone know what this is?"

A Ravenclaw witch raised her hand and said: "It's Mandrake. Adult Mandrakes will cry if they are pulled out of the flower pot, and the crying will be fatal. Young Mandrakes will not be fatal." , but it will make people unconscious for several hours. This pot is for juveniles, assistant teacher."

"That's absolutely correct. If I were Professor Sprout, I would definitely give you Ravenclaw five points. Unfortunately, I teach Defense Against the Dark Arts, not Herbology."

"Then it's easy to guard against him if you know that his cries are lethal. An earmuff will be enough." Chris levitated the flower pot and showed it to everyone.

The students nodded. They had learned the properties of mandrake in the second grade and it was very easy to defend against.

"But what if you carry earmuffs with you in normal life?"

The students looked at each other, obviously it was impossible to carry it with them at all times.

Chris said with some seriousness: "It was a manhunt. The twelve Aurors who were traveling together were all extremely well-trained. With mutual cover and back-up support, they rushed into the home of a fugitive dark wizard and arrested him. When they arrested him, he was already disarmed and smashed the mandrake covered with a bag on the ground. It was a pot of mature mandrake. None of us were aware of this."

"In just one second, the dark wizard who was closest was killed. If it weren't for an Auror who was farther away and could withstand less power, he couldn't help but shatter his bones and smash the pot of grass. Everyone would have died! But that time we Still lost two companions.”

The students' faces all looked bad and they felt a little sad. Two of the more sentimental girls secretly wiped their eyes.

"So how to defend against the properties of mandrake without earmuffs is what we need to learn in this class."

"If you have any ideas, feel free to speak out. Many magical creations and spells are based on a bold idea!"

"Assistant teacher, I think you can use silent spells to quickly apply them around the body." A Slytherin wizard said.

Chris nodded: "This is the first reaction of most people, but the moment you encounter Mandrake, your body will become stiff. No matter how clever the silent spell is, you still need your fingers when releasing the silent spell. By directing a range, magic power can quickly build a position to achieve a silent effect, so this is difficult to establish. Unless you are far away and your body can still move, it will take at least three seconds."

"You're very likely to die during this time."

"So, assistant coach, what if you use apparation to quickly leave the scene?"

It was the Ravenclaw witch who spoke.

Chris snapped his fingers and said, "This is indeed a good method. My first idea was to use this method to avoid him. Disapparation is to directly build your magic trajectory in the body. With a little practice, most people can do it without it." You need to wave a wand to cast a spell, and the response is very fast, and you can escape the scene in less than a second.”

"What's your name?" Chris glanced at her appreciatively.

"Evanna Doug." The little witch said politely.

"Then Miss Doug, five points for Ravenclaw."

"This method is indeed sufficient for many people to use. It is simple, direct and fast. However, when Aurors capture dark wizards, they will cast anti-Apparition spells around them to prevent them from escaping. So it still has limitations."

"So Assistant Coach Will, is there nothing we can do?"

Chris looked at the confused eyes of the students and said, "If there is really no other way, then why am I taking this class?"

"Take out your notes and take notes. This is my unique skill!" Chris smiled mysteriously.

"Since that incident, I've been thinking about what to do when movement is restricted and what to do in emergencies."

"As I just said to Miss Doug, the first thing I thought of was apparation, but it has always been a bit limited. My original idea was to bypass the counter-spell and just activate a short movement. "

"The sound range of Mandrake is not very large, but when I studied the magical trajectory of Apparition, I found an easier method."

"Apparition is to instantly compress one's own magic power into a singularity. Then, in the mind, a spatial beacon of the place where one has been has been constructed to teleport oneself there."

Chris waved his magic wand, and the threads flashing with golden light gathered into a simple human body magic trajectory diagram.

"What I discovered is that by reversing the trajectory of the phantom's disembodiment and changing it a little, the compression will turn into expansion, instantly forming a small space around itself where only its own rich magic power exists."
