Have fun with Resident Evil

"They are the jailers of Azkaban - Dementors," the knowledgeable Hermione recognized these ghost-like guys instantly.

"I heard that Sirius Black escaped from prison. These Dementors may be here to hunt him down," Ron said tremblingly as he looked at the Dementors outside the window.

"He's not in the car too, is he? I heard he might be here to kill you, Harry. After all, back then..." Ron seemed to have heard something from his parents.

As everyone knows, it was Sirius who betrayed the Potter family. So it is reasonable to speculate that he escaped from prison to hunt down Harry.

As the number of Dementors around increased, the temperature in the carriage became lower and lower, and darkness enveloped everything around, and it seemed that even the lights could not penetrate the darkness.

Just as the four of them were looking at each other, a Dementor penetrated the wall of the carriage, entered the interior of the carriage, and gradually approached Li San. It might be because Li San's laughter just now was the loudest.

After all, this Dementor has average intelligence and feeds on human happiness. It will be attracted by the food and may forget the order for a while.

"How dare you, an ugly thing, act so presumptuously in front of me?" Li San condensed a lightsaber in his hand and cut off the Dementor's dog head with one sword. This was the spirit sword technique.

Although Li San doesn't know the Patronus Charm, it doesn't mean he can't fight against these spirits. All the fragments of Voldemort's soul have been destroyed, so why would he be afraid of you little Dementors?

But strangely, the Dementor whose head had fallen off reappeared a head, but it was smaller in size and ran away screaming.

Li San's behavior was like stirring up a hornet's nest, and all the Dementors nearby rushed towards Li San's carriage.

"Expecto Patronus!" Two spells were heard, and then two white lights dispelled the darkness in the carriage. The Dementors were also dispelled by this magic along with the darkness.

One of them was Snape who was standing at the door of Li San's carriage, and the other was Lupin who was driven to the next carriage by Li San.

When the Dementors were dispersed, Lupin's footsteps were heard next door, approaching Li San's carriage. Snape didn't want to meet this enemy, so he chose to leave temporarily.

"Harry, are you okay?" It seemed that when Lupin left, he had already noticed Harry who passed by him.

"How do you know me?" Harry was a little curious about the stranger.

"Who doesn't know the famous Harry Potter?" Ron joked as if to ease his fear.

However, Harry and Hermione were very curious about the method Li San used to kill the Dementors. After Lupin left, they kept asking Li San questions and said they also wanted to learn it.

"The best magic to deal with Dementors is the Patronus Charm, which is the white light that just appeared outside. I couldn't learn the Patronus Charm, so I had to use that last resort!" Li San said that he was powerless to stop them from learning spiritual swordsmanship and could only divert their attention.

Perhaps because he was eager to learn the magic that could defeat those horrible Dementors, Harry ran directly to the carriage next to him where Snape was to ask for advice.

Maybe Harry thought of the three friends in the next carriage, so he simply pulled Snape over.

"This magic will be taught in your Defense Against the Dark Arts class this semester, but since it's Harry's request, I don't mind explaining it again here!" In front of Hermione and Ron's surprised eyes, Snape actually began to give a live teaching demonstration.

A white stag made of white light emerged from the top of Snape's wand, bounced a few times in the air, and then returned to the top of the wand.

"The patronus summoned by each person is not necessarily the same. Mine and your mother's are the same, both are stags!" Snape continued to explain.

In fact, what he didn't say is that the Patronus of Harry's father James is also in the shape of a stag.

Li San actually knew that Harry's patronus would look like this in the future.

After explaining the spell and key points of the Patronus Charm, Ron plucked up the courage to raise his hand and ask Snape a question.

If it were in class at other times, he would never dare to do this, mainly because he saw Snape's friendly expression at the moment.

"Professor, what do you mean by recalling happy things?"

In the past, Snape would have started to get angry, but thinking that this man was Harry's good friend, he could only endure it in order to ease the relationship with Harry.

"Before the Dementors appeared, I heard the laughter and joy in your carriage. You can try to recall what happened at that time."

"Expecto Patronus," the three protagonists began to recite the spell according to the instructions.

White lights appeared on the tips of Hermione and Harry's wands, but Ron's remained unchanged.

"Don't be discouraged. This is a relatively advanced protective spell that requires long-term repeated practice. It can not only dispel Dementors, but also block most evil curses. It is still very difficult. It is very good that you can do it for the first time!"

Harry failed when casting a spell for the first time, and Snape, contrary to his usual behavior, tried to comfort him. In Ron's impression, Professor Snape should have mocked him at this time.

"Neville, why don't you try it?" Ron asked curiously when he saw that Li San didn't move.

"I tried it privately, and it was the same as yours, with no reaction at all!" Li San did not hide anything and directly told his situation. After all, there was a master named Snape who could create his own spells next to him, and maybe he could point out the cause of his spell failure.

Li San didn't think that he couldn't learn this spell, but his method was problematic. After all, his magic power was far beyond that of most wizards in the world, and with the buff rewarded by the system, the power of most of his magic was far beyond that of others.

Take the Knife of Shadows for example. Li San had seen Snape, the inventor of the spell, cast this spell, but its power was much smaller than the one he cast himself.

In Snape's eyes, Li San was considered a talented wizard. Not only was he excellent in all the courses at school, but he also taught himself Apparition in his second year, a skill that only senior students could learn. Snape was curious when he heard that he had not learned the Patronus Charm by self-study.

So he asked Li San to wave the magic wand as he had just said, and then chant the spell while recalling the pleasant things that happened in the carriage before.

This time, a magical thing happened. The Patronus Charm that Li San had tried repeatedly but failed to work before was actually used this time, and it was not like Harry and Hermione's, which only emitted a little white light.

A strange yet beautiful white beast spread its wings and emerged from the top of Li San's magic wand.

Li San looked at it for a while and felt that his guardian angel looked a little familiar. Apart from the wings, the overall appearance was a bit like the adult of his parasite, only more robust.

And with the wings, it looks more like a dragon.

The appearance of this guardian angel can be said to be a combination of the two.

Li San ignored the surprised looks of Harry and the others, and started thinking about the reasons why he had failed in casting the spell before.

Could it be that the memories I recalled in the past were not considered happy memories?
