Just a Defense Against the Dark Arts Professor

The fire in the office fireplace flickered.

However, after Sherlock canceled the spell on the invited Dementor and took off the sack, the coldness that penetrated people's hearts swept across the entire room.

A bone-chilling coldness emanated from the Dementor, and its face, which was covered by its robe, immediately absorbed hope and happiness at Sherlock, who was so close at hand.

This is their instinct to eat, even if they are caught now.

Sherlock didn't care about this. Compared with the straw man in the goblin headquarters, the despair spread by the dementors was nothing to worry about.

He waved his wand and tightened the silver threads that bound the dementor a little more.

It can be clearly seen that the Dementors are in great pain, and what is released by the Patronus Curse is the natural enemy of these monsters.

Although the original owner was not proficient in the Patronus Charm, during his research in Azkaban, he specifically used the non-concrete Patronus Charm to conduct experiments on dementors.

Dementors' favorite food, which is also the most necessary food for survival, is positive human emotions.

They feed on positive human emotions, and then must be fed back with fearful emotions.

In other words, dementors are not just simply sucking out hope and happiness. After sucking away these emotions, the person being sucked has to show emotions of fear and despair to satisfy them.

The reason why the Patron Saint Curse is the nemesis of Dementors is because those silver threads of light only contain positive emotions of hope and happiness, and the summoned Patron Saint is a semi-physical creature condensed from positive emotions.

The patron saint will only have positive emotions and will not produce despair, so the dementors have no way to cause any harm to it, and will be driven away by such strong positive emotions.

But it was just an expulsion.

As the most evil creatures in the world, Dementors cannot be eliminated.

Since the discovery of this monster, there has never been a case of death of a Dementor.

Even the most powerful patron saint spell can only drive them away or reduce their power, but there is no way to truly eliminate them.

Of course, these are the experiences summed up by predecessors. Sherlock plans to try it himself today to see if it is accurate.

He aimed at the Dementor and summoned the Patronus, and the silver bird spread its wings and hovered over the Dementor.

The dementor clearly showed a restless mood. It looked like it was escaping from here, but it was tied to the spot by silver threads and could not move even half a step.

Under Sherlock's control, the Raven Patron finally landed on top of the Dementor.

The dementor seemed to be in extreme pain, with gray smoke constantly coming out of its body. Within a few minutes, it became extremely weak and collapsed on the ground.

But there were no other manifestations after that. The Dementor fell limply to the ground, Sherlock's Patronus stood above its head, and the black air gradually stopped coming out.

At best, the dementors behave as if they have lost most of their power, but show no signs of being killed.

Normal spells, even the Death Curse, are ineffective against them. Physical attacks will not even touch these monsters. The only thing that can affect them is the Patronus Charm.

But the Patronus Charm can't kill them, it can at most weaken their power and drive them away.

After verifying these things, Sherlock can basically understand why the Ministry of Magic finally cooperated with these creatures.

Dementors, who mainly feed on human emotions, must be mankind's mortal enemy.

But there is no way to kill this kind of creature, and normal means cannot cause any harm to them.

Magic like the Patronus Charm is at the highest level of difficulty among defensive spells, and there are very few wizards who can successfully summon a Patronus.

If a large number of dementors were causing trouble everywhere, the wizard would not have enough manpower to drive them away.

Therefore, the best way is to bring them together and give them enough "food" to appease them so that they will not cause chaos in crowded places.

There is no other way to build Azkaban into a wizard prison and send the guilty wizards there to serve as food for the dementors.

The dementor obviously didn't care what its identity was in the eyes of the wizard.

As long as whoever provides them with enough food, they will listen to whoever does it, without any loyalty or credibility at all.

Sherlock smacked his lips as he looked at the Dementor paralyzed on the ground. At first, he thought that there was a possibility that this creature could be completely wiped out, but now it seemed that he had thought of things too simply.

If the Patronus Curse was really lethal to Dementors, the ancient wizards would not have allowed them to remain until now, and would have driven out all these anti-human things.

After hiding the weakened Dementor who had been invited as a guest in a cabinet and sealing it with the thread of the Patronus Charm, Sherlock clapped his hands and went to the auditorium to help Professor Flitwick decorate tomorrow's Christmas decorations. went.

He will still have use for this Dementor later on, but he can't let it go back just yet.

The next day, Christmas Day, Sherlock woke up early and found a small pile of gifts piled on his bedside.

He stared at the gifts for a while, thinking about the gifts he received last year. It seemed that only half of the gifts in this pile were piled so high now.

Of course, Sherlock also sent out many gifts, unlike last year when he only sent Dumbledore a Christmas card.

But the Christmas greetings on the gifts he sent were not written by himself.

Because when he was preparing the gifts a week ago, Harry happened to be in the office. When he saw Sherlock writing the names of the well-wishers on each greeting card, there were Mrs. Weasley, Mr. Weasley, and Dumbledore. Lido, Professor McGonagall, he was so frightened that his face turned pale.

Harry slowly told him that he could actually write these blessings for him.

Naturally, Sherlock didn't agree to him at first, but seeing Harry begging and almost crying, he finally gave in and asked Harry to write the blessing card on the gift instead of him.

When Harry was writing the greeting card on Sherlock's desk, he felt extremely happy and proud.

He felt like a hero, saving all the people like Mr. Weasley who would have been in dire straits at Christmas.

The first thing you do when you wake up on Christmas Day is naturally the time to open presents.

Professor McGonagall gave him another knitted hat, but this time it was pure black.

Mrs. Weasley sent him a pair of woolen pants, and Kingsley sent him an ancient defensive magic file, which seemed to be very valuable.

Others include a set of wand care tools given to him by Fleur in France, and a brand new shorthand quill given to him by Silk.

To be honest, Sherlock was quite surprised to receive Silk's gift. He had never thought that with Silk's personality, he would give gifts to others at Christmas.

The same goes for Fleur. He didn't expect that almost half a year had passed and that little girl in France still remembered him.

The most important thing is that he didn't actually prepare gifts for these two people.

This made Sherlock, who was still accustomed to reciprocity in his bones, feel a little embarrassed. He always felt as if he was a wicked person who didn't understand the world.

But Christmas has already begun, so he naturally has no way to make up for such a mistake. He can only wait until next Christmas to make up for it twice as much.

After opening the gifts, Sherlock went to the auditorium to have breakfast. He also wanted to help Professor Flitwick add some ribbons to the auditorium that was not decorated yesterday.

He did not return to the office in the morning. Instead, he chatted with Professor McGonagall about some teaching matters in the teachers' lounge.

The Christmas atmosphere in the castle this year is obviously much cooler than last year, because there are very few students staying in the school, and together with the single professors who have settled in the school all year round, there are only twenty people in total.

But the atmosphere at lunch was still lively. The joy of Christmas made Harry temporarily forget about Black. Moreover, this morning he also received a Christmas gift of a new type of broomstick "Firebolt" from someone who didn't know who it was.

At the dinner table, under Dumbledore's strong recommendation, Snape reluctantly opened a magic firecracker, and a big witch's hat popped out and fell on his head.

He pushed the hat to Dumbledore with a face, and Dumbledore immediately put it on his head happily.

There was obviously one less person at the dining table today, Lupine did not come over.

Divination professor Sybill Trelawney discovered the incident, and Dumbledore covered it up with the excuse that he was sick again.

In fact, these days happened to be the days when the full moon appeared in mid-December. Lupine must have drank the wolfsbane potion prepared for him by Snape and found a place to transform.

After the Christmas party, Sherlock returned to his office and continued to conduct a series of magical experiments on the dementor.

When night enveloped the entire Hogwarts and the moonlight shone into the room through the glass, he stuffed the half-dead dementor he tortured back into the cabinet, and then took out the hanging hanging around his neck. The locket is viewed in the moonlight.

I found that it seemed newer than before.

The changes in this locket are subtle, but after so many days, it is obvious that it is different from when it first appeared on Sherlock.

Although the whole body still shows a dark golden color, the rust-like spots on the surface have disappeared, as if it had been renovated.

Such changes are enough to confirm Dumbledore's words.

This locket is slowly repairing itself. What will happen when it is repaired is unknown.

Sherlock hoped that it would be as good as Dumbledore said, when it could be opened, that is, when he could take it off his neck.

Judging from its current self-repair speed, this day is not likely to take long.
