Harry Potter: I started checking in from Diagon Alley

This is a relatively basic detection spell that can detect some basic information.

This magic is very similar to the measurement magic used by Ollivander in Diagon Alley.

They are all used to measure some basic body data.

Eric took out another notebook and a quill pen, and with a gentle wave of his wand, the quill pen automatically began to write in the notebook.

Height, weight, limb structure...

Eric recorded all of this information.

Eric even tried to lift the Dementor's cloak, but found it wouldn't work.

The Dementor's cloak, like its body, is part of the Dementor itself.

It is one of the basic elements that constitutes the existence of Dementors, but it is not a physical object.

[Spiritual Stance Activated]

The world turned gray, and Eric focused his gaze on the Dementors.

Dementors are magical creatures that exist purely in spirit form, feeding on human emotions. They have no facial features, relying solely on smell and feelings to perceive their surroundings. They possess a degree of intelligence and comprehension, but are incapable of concrete communication. Being near a Dementor causes one to constantly feel the light around them being absorbed, losing courage and hope, gradually having their inner space filled with nothingness, until they become completely empty and lose their soul.

The most lethal weapon of Dementors is known as the "Dementor's Kiss." The Dementor pulls back its hood, revealing an organ in the shape of its mouth, and aims it at the mouth of its prey, thus sucking out the soul of the victim.

From a spiritual perspective, the Dementors that Eric saw were entirely covered in a gray-black color.

Eric's eyes narrowed as part of the Dementor's body became transparent, including its cloak.

It highlights the gray-black color inside the body.

This is a change that wouldn't occur when he observes other objects from a spiritual perspective.

After looking again, Eric realized that the Dementors hadn't become transparent; rather, they had vaporized in his eyes.

From a psychic perspective, Dementors appear as pure gas, condensed into clumps, and floating in the air, rather than exhibiting their usual physical form.

What does this mean?

Eric felt as if he had found the key to the Dementors' survival, and he focused his mind further, looking into the Dementors' interior.

Now, the Dementors seemed to him like a bubble, a cloud of smoke condensed in mid-air.

Through the gray-black smoke inside the Dementor, Eric could actually sense a malevolent emotion emanating from it.

It contains regret, grief, despair...

These emotions are concentrated within the Dementor, coalescing into the Dementor itself, and constantly influencing those around it.

This is undoubtedly the energy source that sustains the Dementors' survival.

Eric was trying to find out where the core was, like an animal's heart.

After searching around, Eric discovered that there were no cores, or rather, they were all cores.

Every single one of these negative emotions is extremely important to the Dementors; they are inseparable.

Eric maintained this position, took a step forward, and moved a little closer to the Dementor.

The next second, a sudden change occurred.

These emotions seemed to instantly gain their own consciousness. As soon as they sensed Eric's approach, they emanated from the Dementor, maintaining a state of smoke, constantly condensing and constructing several twisted tentacles that drifted towards Eric.

From the perspective of an ordinary person, such changes are naturally not visible.

Eric did not resist, letting the gray-black tentacles gnaw onto his body.

Then Eric suddenly felt a strange sense of sadness and loneliness.

For no apparent reason, he suddenly remembered the most painful thing in his past life.

"As expected, a purely dark creature," Eric muttered to himself.

Eric waved his hand, unleashing a burst of pure magic that shattered the air in mid-air, instantly scattering the approaching gray-black tentacles.

Sensing the threat, the gray-black tentacles returned to the Dementor at incredible speed.

Eric's magical release could not harm the Dementors; that was something only the Patronus could do.

The forces that make up the Dementors simply sensed that Eric was not someone to be trifled with.

In fact, if Eric hadn't only captured one Dementor, he would have tried to have the Patronus kill as many Dementors as possible.

Of course, theoretically speaking, Dementors cannot die.

However, it is also known that they can be harmed by the guardian spirits.

Just like what Eric's giant eagle did to this Dementor.

What happens when these two situations conflict?

Eric was looking forward to it.

I should have caught two more back then.

Regarding Dementors, there remains one question that Eric cannot currently understand or learn through experimentation.

That's how Dementors were created.

They are undoubtedly created beings, but what method was used to create them?

Where did the initial energy come from?

At least in Eric's memory, no wizard had ever attempted to study these questions about Dementors.

Eric did not continue to probe. Instead, he used Transfiguration to create an iron cage, reinforced it with a hardening charm, and placed the captured Dementors inside.

Dementors are not true spirits, and they cannot pass through physical objects or walls, so keeping this currently weak Dementor locked up should not cause any immediate concern about it attempting to escape.

This is important research material for Eric.

After doing all this, Eric glanced at the Dementors without any emotion, then stepped out of Falco's travel trunk.

He thought of Voldemort.

A vessel filled with emotions, but lacking a soul.

What interesting things would happen if one could merge with a soul?

Chapter 58 The Screaming Shack and Black

Having confirmed that the Dementors were still under his control, Eric stepped out of the suitcase.

The new mission has come at just the right time.

The generous rewards aside, the unbreakable oath is also a spell that can be directly linked to the wizard's soul.

Its main function is to restrict the actions of wizards.

Of course, constraints are two-way.

The consequences of breaking the agreement are quite terrifying.

Eric will definitely be visiting the Screaming Shack in Hogsmeade.

As far as he knew, Sirius Black was currently using his Animagus identity to hide in the Shrieking Shack, constantly looking for an opportunity to sneak into Hogwarts, but he hadn't succeeded because Hogwarts was now surrounded by Aurors and Dementors.

Getting to know Sirius Black in advance was something Eric had planned to do anyway.

……

On the last weekend of October, when the students in the castle above the third year had the opportunity to travel to Hogsmeade for the weekend, Eric also happened to emerge from the Honeyduke's cellar.

Eric found this secret passage by relying on his memory while exploring the castle.

On the third floor of the castle's main tower, behind a hunchbacked, one-eyed witch, lies a hidden door.

Simply tap the hunchbacked witch's statue with your wand and say "Separate left and right" to open the secret passage behind the statue.

The secret passage leads to the Honeydukes candy shop in Hogsmeade Village.

Eric emerged from the secret passage, opened the cellar door, and then calmly walked through the flow of people in the store before exiting.

During this time, no one paid any attention to him and ignored him.

They couldn't see Eric at all.

Eric is wearing an invisibility cloak.

The invisibility cloak wasn't his; Eric borrowed it from Harry before they set off.

Unlucky Harry couldn't come to Hogsmeade with the third-year students because his uncle refused to sign his application form, and he had to stay in the castle.

Knowing this, Eric took the opportunity to borrow the Invisibility Cloak.

Anyway, Harry doesn't need it now.

Harry was surprised that Eric knew he had an invisibility cloak, but being straightforward, he didn't think too much about it. Since Eric needed it, he lent it to him.

Eric didn't intend to tell Harry about the secret passage beforehand.

Anyway, in a few weeks, the Weasley twins will give him the Marauder's Map, and Harry will naturally learn about it then.

Eric walked out of Honeydukes, checked his bearings, and turned to walk toward the Screaming Shack outside Hogsmeade.

If nothing unexpected happens, right now, there should be a big black dog named Sirius Black in the Shrieking Shack, figuring out how to sneak into Hogwarts.

Hogsmeade was small, and after avoiding the students who were enjoying their weekend revelry, Eric soon walked to the Screaming Shack.

This is a dilapidated, crooked wooden house. The windows and doorway are blocked by wooden strips. It is the only house around, all alone.

Legend has it that the residents of Hogsmeade would hear strange screams coming from this house at night, and they all thought it was haunted, so the name Screaming Shack came about.

That was actually the commotion Lu Ping caused during his student days.

Every full moon night, with the help of his three best friends, he would go through a secret passage guarded by the Willow Tree to the Screaming Shack to transform.

Lupin's howling was naturally mistaken by the residents of Hogsmeade as a ghost.

After learning about Lupin's transformation night at the Shrieking Shack, Dumbledore, who had arranged for him to do so, did not try to correct the Hogsmeade residents' thinking. In fact, that was better, as it would prevent anyone from approaching the house and make it easier for Lupin to use it.

Of course, Dumbledore could never have imagined that Lupin was never alone.

The doors and windows, simply nailed together with wooden strips, could not stop Eric.

Eric looked around, activated his mental field, and after confirming that no one was there, he took off his invisibility cloak, smashed the door and wooden planks together with a spell, and stepped inside.
