Hogwarts: I am the power of purification

"Harry, we can only stay here. It seems that there are no other empty boxes." Rowling decided to enter this box without hesitation. After all, the person in front of him was Remus Lupin, who played a key role in Harry's academic growth.

From the stuttering Quirrell in the first grade to the bragging king Lockhart in the second grade, Lupin became Harry's mentor and helpful friend. He not only taught him how to cast the "Expedience Patronus" spell, but also taught him a lot of knowledge about magical creatures.

"Who is this person?" Ron noticed this strange man at a glance after entering the box. He frowned and asked in confusion.

"James Lupin," Hermione replied confidently.

"How do you know everything?" Ron opened his mouth in surprise and asked questioningly.

"It's written on the suitcase!" Hermione explained helplessly, pointing to the label on the luggage rack, on which Lupin's name was clearly written.

"Oh..." Ron nodded awkwardly, but he quickly shifted his attention to Lupin: "Then what happened to him? Is he dead? He's motionless." As he spoke, he nervously approached Lupin, as if he wanted to confirm.

Rowling looked at Ron speechlessly. Yesterday was a full moon night, Lupin must have turned into a werewolf again, and he must have gone through a painful night.

Harry saw that Lupin was asleep, so he told Hermione, Ron and Rowling what he had learned from Arthur Weasley.

Rowling didn't take it seriously, after all, he already knew all this, but Hermione and Ron were still shocked.

At this moment, the train, which was originally traveling at high speed, suddenly made a sharp braking sound, and then the whole train shook violently.

Rowling was sitting in the box. He felt something was wrong and immediately looked out the window. Outside the window, he saw a dense swarm of Dementors floating in the air, like a black cloud covering the whole world.

A piercing cold wind suddenly swept past, chilling Harry and the others. Xiao Ke also flew out of the luggage and hugged Luo Lin's neck tightly: "Luo Lin, there is the scent of the Clow Cards..."

Luo Lin frowned, he was keenly aware that this strange force came from outside the car.

"Stay here and don't move. I'll go check out the situation." After giving the instructions, Luo Lin quickly stood up, opened the door of the box and walked out.

Harry wanted to stop him, but Rowling moved too fast and disappeared from his sight in the blink of an eye.

"Don't worry, Harry, Rowling will take care of it," Hermione comforted.

At this time, Rowling walked out of the compartment and came to the corridor of the train. The corridor was crowded with passengers, who looked at everything in front of them in horror. The Dementors were checking the compartments one by one, looking for something.

When they found Luo Lin, their eyes flashed with greed, as if they had found delicious prey. They immediately rushed towards Luo Lin and tried to suck his soul.

However, Rowling was dismissive. He smiled lightly, a faint purifying power flashed in his hand, and then he slapped the Dementor that rushed over and sent it flying.

Luo Lin did not delay any longer and quickly walked out of the train. As expected, he saw that the train had stopped on a bridge. He was surprised to find that the train was frozen! Luo Lin hurriedly looked down and saw that a huge lake under the bridge was also frozen.

"Low Lin, this is a frozen Clow Card!" Xiao Ke keenly noticed the abnormality.

Luo Lin immediately spread his wings, flew quickly into the lake, and hovered steadily in the air. However, at this moment, huge ice cones suddenly appeared on the ice surface, and they attacked Luo Lin at an alarming speed. Luo Lin wanted to summon the fire spirit, but was interrupted. In desperation, he could only quickly flee the scene. At the same time, heavy snow began to fall from the sky.

Luo Lin wondered in his heart: "It's September now, why is it snowing? Has Dou E appeared again?" But he soon realized that this idea was too ridiculous, so he quickly dismissed the idea and turned to look up at the sky.

"It's the Snow Clow card!" Xiao Ke explained as he looked at the sudden heavy snow.

Luo Lin also felt that the two abilities were superimposed on each other, and his wings seemed to be slowly freezing!

Luo Lin flew up to the sky quickly, and a beautiful girl was dancing. As she moved, the blizzard kept increasing!

However, to Rowling's surprise, the girl did not attack him like the other Clow Cards. Instead, she looked at him with a smile, took his hand, and danced a gorgeous waltz in the sky!

Xiao Ke watched the scene quietly from the side and thought: The snow elf is really a gentler guy than the tree elf!

As the blizzard stopped, the snow elf gracefully let go of Rowling's hand, then automatically turned back into a Clow Card and flew back into Rowling's hand like a light butterfly.

"She recognizes your magic power, and this is her way of showing you that the power of magical elements is interdependent and complementary." Xiao Ke explained while looking at the blushing Rowling.

Rowling held the Snow Clow card tightly in his hand and looked at the ground. The Hogwarts Express was covered with thick snow! He suddenly thought to himself, "As expected, the gentler the woman, the more ruthless she is!"

Luo Lin took a deep breath to calm himself down. Then, he flew downwards, muttering an ancient and mysterious spell: "Elf of Fire, please obey my call and use the blazing flames to revive the earth! Melt the snow and melt the glaciers!"

As the spell was chanted, a dazzling light burst out from Luo Lin's body. Then, a magic circle of light appeared under his feet, like a shining star. The magic circle expanded rapidly as he moved!

In the center of the magic circle, the fire spirit was like a blazing flame. It danced with its body, and the temperature of the flame rose rapidly. Wherever it went, the snow melted and turned into rising water vapor.

Luo Lin felt the endless flow of magic in his body and established a close connection with the fire spirits. He directed the flames to move forward, burning the snow along the way and opening up a clear path. The flames flowed along the terrain and eventually gathered into a huge torrent, rushing towards the lake.

At this time, the Frozen Clow Card also showed up. It was a giant wolf with a huge body of ice being bound by the fire spirit! It struggled hard, but couldn't break free from the fire spirit's bondage.

"Clow Card, return to your original form!" Luo Lin raised the Sealing Staff and tapped it gently. As he moved, the Ice Wolf gradually lost its resistance and was finally successfully sealed in the card by Luo Lin.

At this moment, the little wizards in the carriage looked in amazement at the sudden appearance of the snow-covered box, and the blazing fire melting it.

They all began to look for the mysterious wizard with such powerful power. However, due to the snow blocking their vision, they could not see the situation outside. When the snow slowly melted, Luo Lin had already quietly appeared on the lake below.

Because Harry fainted, Lupin used the Patronus to drive the Dementors out of the carriage.
