Under the cloak of invisibility, Aven, Harry, Hermione, and Ron advanced into the depths of Tumbledown Alley.

Although Malfoy is nowhere to be seen, there is only one way to this place, and it is easy to get lost.

They scrutinized the dark magic shops lining the alley, looking for Malfoy, most of them scary-looking, decorated in dark tones, and displayed in the windows with things or horrors that would make you feel bad at the first glance.

They didn't walk fast, they didn't see a single person, and the whole Tumbledown Alley was as silent as death.

Occasionally, a black shadow will suddenly appear behind a window, indicating that someone is looking down the street.

These figures did not ease the horror, but only intensified the tension, because they all looked like ghosts.

"Let's go back, this place makes me feel bad. Ron said hesitantly, looking nervous.

"No, we have to figure out what Malfoy is doing here. Harry insisted.

"He may have entered a store that we missed with him. Hermione said uncertainly, "What's in the depths of Tumbledown Alley?"

"Meow!" Evan whispered in reply.

yes, what's in the depths of Tumbledown Alley?

It's an interesting topic.

In the depths of Tumbledown Alley, behind the dim and dirty alley, there is a mysterious underground world.

It was the dark side of British magic, a fringe of society filled with evil dark wizards, werewolves, vampires, and other creatures that were not accepted by mainstream society, species that hid like house-elves who had lost their owners, and other thieves, crooks, and so on.

Chaos and darkness are synonymous with this area, and the laws and rules set by the Ministry of Magic will never shine here, like sunlight.

For this reason, the underworld is also known as the Dark Zone.

Its origins are unknown, no one knows, and there is even a lot of discussion about whether such a place exists.

The official version of the Ministry of Magic is that the vicious dark wizards, in order to escape the Aurors and the punishment of the law, dug several holes in the depths of Tumbledown Alley to hide, and that's it, there is no underground world at all.

Moreover, this was a long time ago, and even if these dark wizards were not caught, they would not be alive now.

Under the propaganda of the Ministry of Magic, most law-abiding wizards also believe that such a place does not exist.

Mrs. Weasley had spoken to them about it, and she thought that the Underworld was a fabrication, a ridiculous conspiracy theory, just as it was nonsense that the previous Minister of Magic, Fudge, liked to eat goblins.

Fudge likes the elve's gold coins, and he doesn't really want to eat them.

But in reality, only those wizards who have actually come into contact with the dark arts know that this underground world is real.

The first time Evan heard about this place was from Sirius.

After escaping from prison in Azkaban, he hid for a while in a crypt that was part of the underworld.

More precisely, a tiny part.

The so-called underground world is made up of countless crypts connected by the ground of Tumbledown Alley, some of which are naturally formed and some of which have been excavated by man, and the creatures that live in them are also diverse, from human wizards to terrifying magical beasts.

The number of caves is huge, and the area occupied far exceeds the Diagonal Alley and Tumbledown Alley on the ground.

No one can walk through all the caves, and no one can really say they know the place.

In short, it is terrifying, full of all kinds of unexpected dangers. Sirius had warned Evan and Harry not to venture into Tumbledown Alley, and I heard that in the underground world, there are many man-eating monsters that specialize in catching children......

This warning is somewhat ridiculous, but don't doubt that the guy who eats the hearts and livers of children is real in Tumbledown Alley.

The old witches who hide in the shadows and mutter, the dark wizards who are twisted by the transformation of the dark magic, or the banshees who are known for their cruelty may all have such a penchant for cute boys' bodies......

The second time Evan heard someone mention the underworld was from Lupin.

After the war began, Dumbledore wanted Lupin to return to the werewolves to find out and win over the other werewolves.

So, Lupin gave up his job as the editor-in-chief of the newspaper and went into the underworld, taking on the responsibility that disgusted and painful him.

From him, Evan knew that the strongest force in the underworld at the moment was the werewolves.

They occupy most of the caves in the upper layers of the Underworld, using them as their main area of activity and territory.

Originally, werewolves belonged to a small minority, there were not many of them, and their power in the underground world was not the strongest.

At least, it was the same way a few decades ago.

They stayed away from shamans, relied on stealing and killing for food, and were often discriminated against and persecuted.

This situation was completely changed until the appearance of Fenrir Greyback, the king of werewolves.

As one of the most cruel werewolves, Greyback made it his goal to bite and infect as many people as possible.

He wanted to create enough werewolves to conquer wizards, so he specialized in biting children.

He believed that he wanted to bite them when they were young, so that they would grow up away from their parents, grow up with hatred for normal wizards, and become part of the werewolf army, and with his long-term persistence, this terrible plan finally succeeded.

Now, the werewolves have succumbed to Greyback's brutal rule, making the underworld their domain.

They are active there, continuing their evil.

Ironically, most werewolves were persecuted by Greyback.

They should have hated him, but none of the werewolves resisted, instead, they hated normal wizards and those who abandoned them.

They follow Greyback's orders and spread a terrible werewolf virus and an unforgettable hatred.

I don't know if it's influenced by Greyback, the werewolves under his command like to bite children, especially those with strong physiques, because the boys who are infected in this way will become one of them when they grow up and become strong werewolves......

Therefore, this place of Tumbledown Alley is really unfriendly to boys!

The third time Evan heard someone talk about the Underworld was from Voldemort's daughter, Delphi.

In the future he went to, Delphi wanted to infiltrate the minister's office at the Ministry of Magic, and she needed a polyjuice potion.

Regular shops don't sell this potion, but as long as you have the money, you can get anything in the underworld.

She led Evan and fifteen-year-old Riddle to the Underworld, the closest Evan had ever been to that place.
