A week has passed since the start of the school year, and the original freshmen have almost become familiar with the school life at Hogwarts.

However, students are still talking about the mysterious Defense Against the Dark Arts teacher.

On the one hand, although she was young, she had a wealth of knowledge that students could not imagine. She could talk about almost any dangerous animals and black magic. This made many students admire her. Of course, there were also naughty students, but even those students did not dare to act rashly in front of Ellie. The reason was simple, because every time they did something, Ellie would look at them as if they were dead.

Unfortunately, no matter how capable these students are, they are still students. How can they withstand such murderous aura? It would be good enough if they go back and have nightmares. Some of them could not bear it and collapsed to the ground or fainted on the spot.

On the other hand, Ellie's behavior is also very different from that of many wizards. She never calls ordinary people Muggles like other wizards do, but always uses the terms "ordinary people" and "wizards" when speaking. This is very popular with most children born in Muggle families. Of course, some children from pure-blood wizard families are very dissatisfied with this, but they don't have the courage to risk their lives to protest to Ellie...

The reason is simple. Once they dare to provoke Ellie, it will not be as simple as deducting points. Ellie will also use a punishment method that Hogwarts teachers will never use, which is... running laps!

That's right, if someone makes loud noises, disrupts order or breaks the rules in her class, not only will their house be deducted points, but they will also have to run around Hogwarts school - of course, in order to prevent them from being unwilling or doing anything, Ellie will also cast a "running spell" on them, and unless she stops, these people will keep running.

Until death...

Because of this, few students dared to disobey this petite girl who seemed harmless. Even Ron's two brothers, who loved to play pranks, behaved well in front of her. In their words, "The way she looked at us was not like looking at human beings, but like she was selecting two pigs to be slaughtered..."

So now in the entire Hogwarts school, one of the most popular topics among students after dinner is - "Who is Teacher Ellie?"

No one thought that she was just an ordinary little girl, but her true identity was a mystery. Even if they mustered up the courage to ask other teachers, they only learned from them that this girl was invited by Dumbledore himself to be the Defense Against the Dark Arts teacher, but no one knew who she was.

Except for Dumbledore.

Of course, the students didn't have the courage to ask Dumbledore, so they discussed the matter more and more eagerly in private.

First of all, the hypothesis that she is a vampire has been disproven because students have seen her basking in the sun outside more than once, and vampires obviously don't bask in the sun.

Some people also say that she might be a legendary fairy, but there is no evidence.

Some people also say that she might be the messenger or incarnation of the god of death...this is also just speculation.

Of course, there is one thing that makes her very fatal to students.

That is, as a teacher, Ellie is actually quite inconspicuous.

The other teachers were either tall and easily visible like Snape, or had unique features. In short, if you saw an adult, you would most likely guess that he was a teacher.

But Ai Li is different. After all, she looks like just an eleven-year-old girl. Although her white hair and red eyes are very conspicuous, she has a very strange ability to hide herself. So many times when students want to do something bad, they don’t realize that Ai Li is staring at them in the crowd... Well, for a student, there is nothing more terrifying than this.

It's like doing something naughty during class and being watched by the head teacher through the back door window.

To be honest, Hermione was of course concerned too, but now she was more worried about something else.

"Are you sure you and Malfoy want to have a wizard duel tonight?"

She stared at Harry Potter with eyes wide open in disbelief. She had heard the conversation between Malfoy and Harry during dinner and knew that the two were planning to duel, but Hermione really couldn't understand it.

"Do you know how many points Gryffindor will lose if you are caught? You are so selfish!"

"This is none of your business."

"All right……"

Hermione was speechless after hearing what Harry said.

"I hope you guys stay in the dormitory obediently, so I have to tell you one thing, Teacher Ai Li will patrol every night, and you will be dead if you are caught!"

“…”

This time, Hermione's words stunned Harry Potter and Ron, and the atmosphere became somewhat dead silent for a moment.

"You, how do you know?"

"I saw her. I met her when I came back from the library one day. She was about to go out, so I curiously asked her where she was going. Then she told me that as a teacher of Defense Against the Dark Arts, she would also be responsible for patrolling at night... You don't want to die, do you?"

“…”

Hearing this, Harry and Ron looked at each other and swallowed involuntarily. They still remembered the scene in the first Defense Against the Dark Arts class when Ellie drew out the dagger and stabbed Malfoy's hand without hesitation. Just thinking of this, they already felt a dull pain in their fingers.

"But, but what if Malfoy laughs at us for being cowards?"

"I'll tell Teacher Ellie that if she finds out that Malfoy really dares to go to the appointment today, he will be the one in trouble tomorrow!"

As an excellent student, Hermione obviously didn't think there was anything wrong with telling tales to the teacher, and although Harry and Ron felt that it was a bit unfair, between death and being laughed at by Malfoy, they chose the latter.

After all, the first thing they learned in the Defense Against the Dark Arts class was that staying alive is more important than anything else.

When you die, everything is gone.

It turns out that Malfoy's desire to survive is not weak. Ellie walked around the school but didn't see any trace of him - obviously he would not be stupid enough to put himself in the spotlight.

So at lunch time the next day, Ellie found Harry and Ron.

"Malfoy didn't show up."

She stared at the two of them and spoke calmly, while Harry and Ron looked a little panicked.

"... Teacher Ai Li..."

"I know you are stupid, but don't be stupid enough to be taken advantage of by others."

Ellie didn't even bother to listen to Ron's nonsense and looked directly at Harry.

"You have to remember that you and Malfoy belong to different houses. Your life or death has nothing to do with him. I hope that when you act, you should not always consider yourself, but consider the collective... Everything you did because of Malfoy's provocation is of no help to Gryffindor... Of course, if this is your own choice, you must bear the consequences."

At this point, Ellie glanced at the Gryffindor table.

"Where's Hermione?"

"this……"

In response to Ai Li's question, both of them showed uneasy expressions.

"Well...we don't know..."

"Who knows where she went."

Harry answered hesitantly, but Ron obviously didn't care and even looked a little unhappy.

"She doesn't have many friends anyway. Maybe she's hiding somewhere crying by herself."

“…”

Hearing this, Ellie glanced at Ron and turned to leave. As he watched Ellie leave, Harry pulled Ron.

"That's not a good way to put it."

"What's the problem? She's a nightmare to begin with."

Thinking about what happened in the witchcraft class today, Ron seemed very angry.

"She despises me, you know, Harry, she thinks I'm too stupid, and she's always against us! Humph! I don't care about her!"

After saying this, Ron buried his head in his lunch again. Harry looked at Ron speechlessly, shook his head, looked away, and started to enjoy his lunch again.

Hermione didn't show up for the rest of the afternoon, and didn't even go to class, which caused a lot of discussion among people, but of course Ellie knew where she was.

In fact, when she reached the girls' room, she could clearly hear Hermione sobbing.

So Ellie walked to the bathroom door and knocked.

“Who…is it?”

"I."

"Hey? Teacher Ai Li?!"

Hearing Ellie's voice, Hermione in the bathroom was obviously a little surprised. She hurriedly opened the closed bathroom door and appeared in front of Ellie with two red and swollen peach-like eyes.

"What happened?"

Looking at Hermione whose eyes were red and swollen from crying, Ellie asked, while Hermione lowered her head, not knowing what to say.

"Anyway, let's get out of here first, and talk later."

As she spoke, Ellie stretched out her hand to Hermione, and Hermione nodded. But just as she was about to walk out, suddenly, a dull "bang bang" sound came from the door. The two turned their heads and saw a tall giant monster blocking the door with a wooden stick.

“Ah! A giant monster!?”

Seeing this horrible monster, Hermione was so scared that she sat on the ground, while Ellie frowned and stared at it - in the original book, the reason why this troll appeared in the dungeon was that Professor Quirrell deliberately put it in to attract other people's attention, but now Professor Quirrell has been killed by herself, so where did this troll come from?

The troll is a monster with extremely low IQ. It would be impossible for it to come in without someone guiding it.

Could it be that after he killed Professor Quirrell, Voldemort found a new host?

Is this the repair of the world line?

"Ai, Teacher Ai Li!?"

At this moment, the giant monster also discovered the two of them and walked in with a low roar, while Hermione shrank behind Ellie in fear. Although she was also a very good student, it was the first time for her to see such a huge monster in real life.

"I, what should we do?"

"Don't worry, it's actually very easy to solve. In fact, anyone can easily solve the giant monster."

"Yeah……?"

"certainly."

As she spoke, Ellie pulled up her skirt and pulled out a revolver from the leather holster tied to her thigh. Then Ellie held the gun with both hands, aimed at the giant monster's head, and pulled the trigger.

"Bang!!!"

Along with the sound of gunfire, the next moment, a bloody hole suddenly appeared on the giant monster's forehead. Then the tall giant monster fell heavily to the ground wailing, and died.

“…”

Hermione was completely stunned at this, while Ellie turned around and put the gun back into the holster before turning to look at Hermione.

"That works much better than a wand, doesn't it?"
