Dementors are humanoid dark magical creatures.
It wore a black cloak, and its entire body looked as if it had rotted in water, with scabbed palms exposed, somewhat resembling the initial stage of human decomposition after death.
There were no facial features on its face, only a small circular hole where a mouth should have been. That was its method of attacking other creatures, capable of absorbing people's happiness. Wherever a Dementor was present, the surrounding light and warmth would be slowly obscured by it, making other creatures gradually feel darkness and cold.
If it attacked mouth-to-mouth, it could even make the attacked creature lose its soul. This attack method, which produced a similar result to the Killing Curse, was also known as the "Dementor's Kiss."
For Hogwarts students, at the Ministry of Magic's request, Dementors naturally could not use the Dementor's Kiss; at most, they would just suck a little of the Wizards' happiness.
Draco was facing exactly this situation now.
The Dementor did not give him a direct kiss; it merely formed a small vortex in front of its mouth, preparing to devour his happiness so it could have a full meal.
The prisoners locked up in Azkaban didn't have much happiness, but now, in this train, these Little Wizardsall looked like tempting, fragrant food in their eyes.
Seeing that Draco didn't react, Arthur pushed him again, saying with a hint of exasperation, "Draco, where's your courage? Do you want to be like this for the rest of your life?"
"Of course not, I… I also want to be a hero." Draco's voice trembled slightly, but he still tried hard to raise his wand and shouted loudly, "Expecto Patronum!"
A pure white peacock slowly emerged from the tip of his wand.
The moment the peacock appeared, Draco instantly felt warmth; the cold and darkness brought by the Dementors seemed to vanish in an instant.
The small vortex created in the Dementor's mouth also disappeared. Faced with something that restrained them like a Patronus, the Dementor also wisely did not continue to act, and after checking that there was no criminal Sirius in the carriage, it left.
After driving away this Dementor, Draco's face was also beaming with an unusually joyful smile. He had never imagined that he would have this day, to be able to drive away a Dementor guarding Azkaban.
Courage sometimes needs to be cultivated, just like Harry in the original story. Now that Draco had gained a sense of accomplishment, it would naturally bring about some changes in him over time.
At this moment, he said to Arthur with a slightly inflated sense of pride, "Arthur, let's go out and save the other Slytherins. You are the King of our Slytherin, with you taking action, you will definitely drive away those Dementors in one go."
"If you hadn't mentioned it, I would have almost forgotten about such a thing, but isn't this 'being a king' just for fun?"
"That's different; before, we were young, but now we're in third year, and with you saving them this time, I'll make sure they listen obediently from now on."
Arthur thought about the somewhat out-of-control Vampires and Werewolves on the continent of Europe, and a hint of interest in cultivating some subordinates was sparked.
In case Vampires and Werewolves really entered Britain in the future, he wouldn't be at a disadvantage in terms of intelligence.
However, he still planned to follow the previous plan: let Draco negotiate with them, and he would simply provide the deterrent force. For some Slytherins, he found it difficult to truly believe they would be loyal to him.
Arthur led Draco out of the carriage.
At this time, Dementors were constantly flying outside the entire Hogwarts train, and occasionally one or two Dementors would slip into the train, causing the Little Wizards to let out sharp screams from time to time.
Upon seeing this, Arthur raised his Unicorn horn wand and summoned a Unicorn Patronus using the Patronus Charm.
Previously, he had always used the magic of Soul Guardian to summon the Unicorn, but now he temporarily did not want to expose the fact that he could harm Dementors, at least not until he had captured enough Dementors.
So he summoned the less conspicuous UnicornPatronus. However, Arthur's 'inconspicuous' Patronus, in the current magical world, was already conspicuous enough.
Unicorns are famous magical creatures, and among the Wizards in the current magical world, only Dumbledore and he possessed a Patronus in the form of a magical creature.
Not to mention that his Unicorn was also a bit different, with a pair of large wings on its back.
Draco gasped in admiration when he saw the Unicornagain. It was Arthur who had used this beautiful Unicorn to entice him onto the path of learning the Patronus Charm.
Because the train corridor was narrow, the Unicorn, under Arthur's control, began to appear somewhat ethereal. Like a water-element magical creature, it swam through the train's corridor.
All the Dementors in the Unicorn's path were driven out of the train as if struck by a current of water.
Draco also summoned his Peacock Patronus again and ran in the opposite direction of the Unicorn. Excited, he also wanted to experience what it felt like to be a hero and the center of everyone's attention.
Soon, all the Dementors were driven out. They floated above the train, not leaving, but also not daring to approach.
Arthur didn't indulge them either; since he had taken action, he would drive this group of Dementors away completely.
As the light from his wand flickered, control of the Unicorn Patronus was transferred to Charlotte.
The Unicorn also shot out of the train the next moment, displaying its truly massive body above the train. The huge wings hidden on its back fully unfurled, making it much wider than the train.
As it slowly began to run, the thunderous sound of hooves seemed to follow.
The Unicorn ran higher and higher until it reached the same altitude as the Dementors. Then it began to charge, its huge wings like a sharp greatsword, crashing fiercely into the Dementors' bodies.
The intense pain and an uncontrollable sense of unease made all the Dementors begin to flee.
They couldn't die, but the powerful Patronus made them feel an unbearable pain, a pain like small knives constantly piercing their brains, leaving them with only one thought: to escape.
This Unicorn Patronus they faced this time was even more different from the Patronuses they had encountered before, making them feel as if they had almost died.
Currently working for the Ministry of Magic, all they wanted was to have a feast at Hogwarts, not to endure unbearable pain or lose their lives here.
Upon seeing all the Dementors driven away, the Little Wizards who had poked their heads out of the windows let out cheers.
These cheers made the fleeing Dementors unable to resist looking back, but the Unicorn standing above the train still made them abandon that idea.
It is also worth mentioning that among those Dracosaved were Ginny Weasley and Harry Potter, among others.
This made him even happier than winning first place in Quidditch; he didn't know how uncomfortable Harry would be when he faced him in the future.
Harry had already been on the verge of fainting in front of the Dementor, and it was he who drove that Dementor away. He had saved Harry's life, so as long as he brought this up whenever he faced Harry in the future, he didn't know how he could lose.
