He pulled out his magic wand and used fluorescent flickering to illuminate the carriage before returning to his seat.
"Is the train broken?" Harry asked hesitantly.
"I don't know, but I feel it's not a good thing." Hermione said, shivering a bit, "I remember many historical events, like some big figures being assassinated, all happened on trains—I very much suspect this time..."
"Do you think there's any big figure on this train?" Harry waved his hand with a smile, "Don't worry, I think it's just a train malfunction, that's why it temporarily stopped."
Ron, using the light emanating from Harry's magic wand, breathed onto the window and rolled up his sleeve to carefully wipe it.
"Look, there seems to be someone outside." Ron said to Harry and Hermione, "Look carefully, isn't there a silhouette floating in the sky?"
"How could there be someone floating in the sky? You're just adding too much homework to your magic." Hermione said, frowning, "What do you think that is, a ghost?"
Before she finished her sentence, Professor Lupin woke up from his sleep.
He used the light from Harry's magic wand to see Harry's face clearly.
"Stay in place and don't move, Harry." Professor Lupin said to everyone, "Outside seems... not something welcoming—I know what that is."
"What is it?" Ron asked curiously, "Professor, do you know what those are?"
"Dementors." Lupin told them, "Stay here, do not move, I'll go to the front to find the conductor and ask what the situation is."
With that, he stood up, flames ignited in his hands, enveloping his arms, and then he left the carriage.
"Wow, he must be something." Ron said, watching Professor Lupin's back, "Did you see those burning arms? He must be a man skilled in close combat..."
"Indeed cool." Harry nodded and said, feeling like he had seen that face somewhere before.
However, the carriage shook again, and soon, they felt as if something got on board, the temperature in the carriage was getting colder and colder.
"It's just the end of August, why is it so cold?" Ron said, teeth chattering, "Oh my god, I feel like I've entered winter, it's that cold..."
Before finishing his sentence, a terrifying scream was heard.
Soon, the carriage door slowly opened.
By the light from the magic wand, they clearly saw what kind of thing opened the carriage door.
It was a monster cloaked with a robe, tall enough to reach the ceiling, its face completely hidden under the hood; a hand extended from the cloak, emitting a faint light, gray-white, skinny, and scabbed, disgusting like something dead soaked and rotted in water.
The hand revealed itself for less than a second, and as if sensing the gaze of the three, it suddenly retracted into the folds of the black robe.
Then, the thing beneath the hood, regardless of what it was, took a breath, long and slow, trembling as if striving to draw in something other than air from the surroundings.
It was a Dementor, sucking away the happiness from the carriage.
"Ugh..."
Ron and Hermione instinctively said "ugh," feeling like their happiness was being drained by this thing.
Harry felt its malice—whatever it was doing, Harry felt he couldn't just let it keep absorbing happiness there.
A sapphire blue flame suddenly ignited around Harry's body, attracting the Dementor's attention, as if seeing something terrifying, it swiftly retreated.
However, Harry had no intention of letting it go, the sapphire blue flame leaped out, looking from the outside, it was as if there was a sudden explosion in this compartment, and that flame completely engulfed this Dementor.
The flame showed no sign of stopping, as if it had its own intelligence, starting to sweep toward all directions of the carriage.
The Dementors in the carriage noticed this disturbance over here and fled swiftly, trying to stay far from this sapphire blue demon fire.
The Dementors farther from the compartment ran fast, quickly retreating from the carriage, escaping the painful baptism of the flame—but those two Dementors closer were unfortunate, under the gaze of their companions, they were engulfed by the flame, leaving only traces of flying ash.
Harry walked out from the compartment, still playfully tossing a ball of sapphire blue Ancient Burei Immortal Fire, surrounding the Ancient Burei Immortal Fire there was still a bit of black flame, dim as if it swallowed the surrounding light.
Ancient Burei Immortal Fire, separated as Ancient Burei Immortal/Fire, is not Immortal Fire, but a flame called Gubraithian (Ancient Burei Immortal).
This flame can burn eternally, extremely hard to control, renowned alongside Fiery Fire, capable of harming Dementors.
The Dementors watched him from afar, warily eyeing the compound flame in Harry's hand, with no intention of approaching for a confrontation.
Harry took a step forward.
The Dementors retreated one after another, if anyone who understands Dementors were here, they would horrifyingly discover—fear itself also fears.
The train never started, and the Dementors surrounded the carriage, without any intention of leaving.
But soon enough, the Dementors scattered one after another, and the train restarted.
Harry extinguished the flames, re-entering the carriage.
"So cool, Harry." Ron praised with a thumbs up, but his small face looked a bit bitter: "It's just somehow I feel as if I'll never be happy again?"
