Professor of Pharmacy at Hogwarts

In the room, the four Harrys were still arguing. Suddenly, a blue line of fire flashed past. Then, the scenery outside the window was replaced by blue flames, and the wildness and mountains could no longer be seen.

"Wow!"

"stop fighting!"

Ron rushed to the middle of the four people and yelled, pointing at the flames outside the window and shouting in horror

"What is this! Oh my God! What is going on! Did we meet a dragon!"

Harry and Hermione also stared blankly at the spectacular scene outside the window, at a loss.

Although they are freshmen and have no idea about wizards and spells, they also know that such a large-scale spell is definitely not something ordinary wizards can do.

Compared to these three rookies, Fred and George know a lot more.They recognized the magic spell outside the window at a glance.

The twin brothers were lying on the window, looking at the blue flames outside the window obsessively, without saying a word.

At this time, the entire train was completely boiling.

Both seniors and freshmen were lying on the windows, looking at the flames outside in surprise, and exclaimed.

After the upperclassmen, especially the sixth and seventh graders, recognized the fire escape guard and thought of the battle recorded decades ago from their parents or books, their expressions changed.

Fire Escape, Paris, Grindelwald, Dark Lord, Blood Covenant, Dumbledore...

Words popped out of the students' mouths one by one, quickly causing panic and commotion.

inside the cab.

The conductor stared dumbly at the blazing flames outside the window, muttering dully, "Crazy! Everyone is crazy! Crazy! Crazy!!"

The middle section of the train.

Malfoy was so frightened by Alexis's actions that he froze in place and did not dare to approach Alexis at all.

Alexis rested for a moment, raised the wand again, and the faint blue flame floated out, blending into the fire dragon outside.

The flames wrapped around the train swelled in the storm, rushed to the roof, and slowly closed.

At this time, the entire train seemed to be covered with a blue cover, and the flames completely covered the train, completely cutting off the idea of ​​any creature entering or leaving.

Top of the train.

A figure as short and fat as a rugby ball was lying there, holding on to the roof of the car with both hands, his face pressed against the car, and a pair of green bean-sized eyes wandering around.

"Dammit Alexis! You're a lunatic!"

Peter Pettigrew cursed in a low voice, his body facing the fierce wind, and his fat body trembling wildly. He was so frightened that he quickly clung to the car, not daring to make any unnecessary movements.

"Damn Alexis! Damn Grindelwald! Damn Dumbledore! Damn! Damn!"

Peter Pettigrew held his body still, mumbling curses.

At this moment, he was feeling frightened and anxious.

It was getting dark outside at this time, and there was still less than an hour until Hogwarts.

He must escape within this hour, otherwise Alexis will turn over the entire Hogwarts Express once the train arrives and stops!

By then he will be unable to escape, and it will only be a matter of time before Alexis finds him.

Peter Pettigrew couldn't help but shudder when he thought of Alexis's life-threatening and ruthless attitude when he, Lucius, Bellatrix and others blocked Alexis from going to Godric's Hollow 11 years ago. Shivering, the fat on his face trembled.

No, we must find a way!

Peter Pettigrew held his wand in his broad front teeth and squirmed inch by inch, closer to the car window. The next moment, his fat body shrank sharply and turned into a fat, gray rat.

The mouse was completely blown up into the air by Da Feng. It let out a squeaking scream, kicked its limbs desperately, held on to the car window, and struggled to get into the car.

…………

Inside the Hogwarts Express.

Alexis was resting in the room next to Harry and others with her wand in her arms.

Although he looked down on Peter Pettigrew as a person, he thought that Peter Pettigrew was a selfish and timid guy - this can be seen from his Animagus form.

But he wouldn't really despise Peter Pettigrew.

It has been 11 years since the last time they played against each other. No one knows whether Peter Pettigrew has improved.Peter Pettigrew was familiar with his fighting style, but he didn't know much about Peter Pettigrew.

Therefore, Alexis needs to recharge her batteries and prepare for the next battle.

The Hogwarts Express continued to move forward with a bang, and despite the noise made by Alexis before, the students on the car were not sleepy, but they were not interested in talking.They were just hiding in the room with their friends in twos and threes, whispering.

It was getting dark outside, and the train began to slow down and finally stop.

The quiet train carriage became noisy again. Everyone breathed a sigh of relief, lined up with their luggage, and prepared to get off.

In their opinion, no matter what happened, they had now arrived at Hogwarts, and they were safe on Hogwarts territory.

The carriage door opened, and the faint blue flames looked very eye-catching in the night.

Students pushed and gathered at the door, but no one got out of the car.There was an exclamation from the platform.

"Oh my God! Who did this! Go and notify Dumbledore!"

In the crowd, several Harrys huddled together and looked worriedly towards the room where Alexis was.In their minds, Alexis was definitely going to be out of luck.

"Maybe we should explain it to Mr. Alexis."

Harry whispered.

"But we don't know what happened!" Hermione was also worried about Alexis' situation.

Just as several freshmen gathered together to discuss in low voices, the door to the room opened.

Alexis walked out wearing a windbreaker and holding a wand with a stern expression.

The students who were busy discussing immediately fell silent, and their eyes were all focused on Alexis.

Alexis walked through the crowd expressionlessly, and wherever he went, people moved out of the way until they were standing at the door.

He stepped off the train first, and the blue flames automatically opened a gap that could only allow one person to pass through.

"Alexis! Did you do this?"

A big man wearing an animal skin cotton-padded jacket exclaimed. He was more than three meters tall. It could be seen at a glance that he had the blood of a giant in his body. He held an oil lamp and illuminated the shaggy beard under his chin. It seems a bit intrusive.

Alexis nodded "Peter Pettigrew is in the car."

He explained briefly, clapped his hands and said, "Okay, Hagrid, now let the students line up and get off the bus along the gap."

"Peter Pettigrew!" Hagrid's voice suddenly rose. "Is this the person you said betrayed James?"

Alexis nodded.

"But they said Sirius Black did it!"

Hagrid said.
