At night, Hogwarts Castle is lit up.

The two young men leaned on each other and sat quietly on the top of the castle tower, looking into the distance and looking at the bright starry sky of the autumn night.

Hermione rested her head on William's shoulder, dangling her legs, and sang a Scottish folk song softly, her voice crisp.

In the castle under the butts of the two, there were also people singing. Halfway through the dinner, it was full of laughter.

After some time, William unfolded a map of Hogwarts, which was densely packed with countless lines and names.

Finally, Blake's name appeared.

He followed Duke Honey's secret passage and emerged from the statue of the Hunchbacked Witch, like a ghost, silently following the path towards Gryffindor House.

Judging from the map, Blake stayed at the gate of Gryffindor House for a long time, unable to enter, and at one moment, the door was suddenly opened.

He burrowed into the Gryffindor common room.

At the moment, there are only two cases, the door opened by the fat lady herself, or someone opened the door for Blake.

But a closer look at the map reveals that the Gryffindor common room is empty, save for Blake's name.

It seems that it can only be the door opened by the fat lady!

Black entered the common room, but did not enter the dormitory, where the trap set by Peeves, and the armor guards placed by Professor McGonagall, stopped him directly.

"Shall we go and catch him?" Hermione asked.

"No, our goal is to stop the Dementors from entering the castle." William said.

Dumbledore made it clear that their mission was to stop the flood of Dementors into the castle.

Hogwarts Castle is unlike any other place in that it has countless rooms. Once the Dementors invade and search for Blake, they can easily get trapped in certain rooms.

If you deliberately hide inside, you may even attack a lone little wizard.

If you don't do it well, countless lives will be lost.

Compared to Blake, a large number of Dementors is the big problem.

There is actually a subtle meaning to the principal.

Blake infiltrated the school through a secret passage, and it was impossible to alarm the Dementors, but they did, and there was something wrong with it.

It can only be said that someone found Black and was deliberately luring the Dementors in, wanting to ...... Kill him!

All the teachers and students were in the common room, and Ron, the only one who went out, was also in Snape's office...... So, who did it?

William thought for a long time, and could only think of the ...... Tom had left at school Inner ghost!

But then the question arises, why did he, one of Tom's inner ghosts, have to risk exposing himself to lure the Dementors and kill a recognized Death Eater, Black?

In a way, they should be "allies".

Although there are allies in the special pit, it is the traditional art of the Da Hao Empire, but it also takes time to sell teammates.

William is now more interested in this inner ghost than Blake, whom the Headmaster used to 'test' Harry.

He even thought about plotting a rebellion and giving Tom a Mission Impossible!

Sure enough, something unusual happened very quickly.

The two Dementor guards at the door, who had been quietly guarding there, suddenly smelled something special.

Dementors have no eyes, and with their "cherry mouths", they are invincible, and they can even 'see' through the illusion spell and the cloak of invisibility.

William was sure that the inner ghost was in action, and that he was deliberately luring the Dementors into the castle.

It's also very simple, just go through the gate.

There are no little wizards going out at this point, and the wizards who enter the castle will be mistaken for Blake by the Dementors...... Here it comes.

But bizarrely, through the map of Hogwarts, William did not find anyone's name at the school gate.

The Hogwarts Magic Map, derived from the Living Point Map, is a cold magical 'tracking charm' set up by Marauders in the school.

Very few people know about this spell, which is why so many maps have been sold, and no young wizard has ever been able to crack it.

But if you cast a spell on your name, you can hide your position and become unmarkable.

This is a very complex and advanced magic, and it is said that Voldemort cast a spell on his name.

So for a long time, everyone replaced it with "mystery man".

Another way is to know the tracking charm, which can hide your location and not appear on the live map.

Naturally, it cannot be displayed on the Hogwarts map.

The maps sold in the Akali Mystery Shop are all in this pattern. They only show the buyer's location and cannot flag anyone else.

Obviously, the inner ghost either casts a spell on his own name, or knows how to 'track the spell'.

William transforms into a sea eagle, and Hermione rides it with ease.

With his wings spread out, a breeze blowing, and he staggered and flew away, sweeping Hermione across the campus.

Eventually, it landed on a stone pillar next to the cast-iron door of the school.

The two of them in the state of the illusion spell looked down carefully.

The Dementors had already stepped into the campus, slowly sliding forward.

The inner ghost should be nearby, but William couldn't see the other party.

The man was clearly cautious, not only hiding his name, but also using a disillusionment charm or invisibility cloak.

William waved his wand and said softly, "The invisibility cloak is flying!" ”

But the Flying Spell didn't respond.

It seems that the other party is not wearing an invisibility cloak, but a master of illusion spells, and even William can't detect it.

It's a cautious inner ghost!

The dementor finally couldn't hold it anymore, and the two guys suddenly flew towards the sky, their black robes fluttering lightly.

They emit a screaky "squeak", like a poorly contacted wireless telegraphy.

Soon, the Dementors stationed at the entrances, as well as those in the Forbidden Forest and the village of Hogsmeade in the distance, were all drawn in.

One after another, the black robes came straight to the castle, and there were no less than three hundred of them.

There are too many Dementors, and it seems that they have been frantically making up for their development lately, secretly creating people.

"What to do? Hermione asked.

William still looked at the castle from afar, and he was sure of many things, but he didn't still find them...... Who is the inner ghost?

After half a sound, he breathed a sigh of relief and said, "There are so many Dementors, we can only bring them together and deal with them." ”

"How do you attract it, and do you still use happy memories?" Hermione asked.

"Gourmet temptation is one way, and there is also a way to attract strangers, called ...... Pull hatred! William chuckled:

"Hermione, you say, if we release the captured Dementor, will the other Dementors save it when they hear its cries for help?"

Hermione was stunned and said seriously. "Definitely."

"Where are you going to put the Dementors?"

"The place we both go to the most!"

……

……

8th floor of Hogwarts Castle,

A smooth door was opened,

Countless Dementors slid in at the sound of a cry for help.

"There's only one last thing left." Moments later, William appeared in the doorway, waving his wand.

"Divine Guard!"

A silver sea eagle flew through the gate and headed downstairs. It's going to the Great Hall to give Dumbledore a warning.

William certainly didn't manage to lure all the Dementors over, and the rest was left to the professors.

William and Hermione closed the door, and from the outside, the door was completely gone, turning into a wall.

"Shut the door and beat the dog...... Finish! ”

……

……

The Dementors slid towards the spot where their companions were calling for help, and one of the Dementors seemed to smell something delicious.

As a small clever ghost, it secretly broke away from the large army and flew to the other side.

It turned left and right, passed a troll specimen, flew for a short while, and finally stopped in front of a large cabinet with a blistering surface that looked like it had been splashed with strong acid.

Next to the cabinet, there was a broken bust of an ugly old wizard, and a rusty ...... on one side Royal crown.

It sniffed hard, smelled the soul. It opens its "cherry mouth" and prepares it during the mission,

Secretly add a "chicken leg" to yourself!

It's treated as overtime pay.

This...... Not too much, right?!
