The main difficulty in summoning demons is to successfully build a demon altar to create a purely magical creature. Pen "Fun" Pavilion www.biquge.info

Building a demon altar is very difficult, requiring a lot of materials and evil bloody sacrifices.

Most of these things Evan can't collect, and he won't use them.

Not to mention, the process of building a demon altar and summoning a demon for the first time is very dangerous and prone to accidents.

If you cast this kind of profound black magic, you risk losing your life if you are not careful.

With the superficial knowledge that Evan currently possesses, there is not even a 1 in 10,000 hope of success.

Under the combination of various unfavorable factors, he naturally would not try the summoning method recorded in "Secret of Cutting-edge Black Magic".

But if there is a demon altar that is successfully activated, most of the problems can be solved easily, and there are not so many worries.

As long as the conditions are met, the demons that have already been created by the altar can be summoned.

All that needs to be done is to meet the conditions required by this altar and use magic to enslave the summoned demons.

With Aiwen's current strength, there is a good chance of success.

Evil and taboos aside, demonic magic is very powerful, far beyond black magic in the general sense.

Harness a powerful demon that can help wizards defeat the vast majority of their opponents.

Judging from the magic traces around it, this demon altar is capable of summoning a high-level demon with the ability to attack with ice.

If he had such a powerful helper, Aven's last battle against the Sphinx would not have been so difficult.

You don't have to wait that long until you find the vampire of Keresis to help you get into the ruins.

An unknown demon who can help Evan do a lot of things that he couldn't do before.

There are a lot of people around Ai Wen who are dragging his feet, but there are few who can really help him.

To be honest, after seeing this activated demon altar, he was somewhat moved.

But now it's not about summoning the demons, there's a lot more to figure out.

"Dobby, let's go in and have a look!" said Aven.

He walked down the steps and tapped his wand at the ice wall in front of him.

White mist kept coming out of the wand's end, and soon, the thick wall of ice melted into an entrance.

Evan led Dobby into it, and while he was shocked, he recognized the whole picture of the entire demon altar more clearly and intuitively.

The altar is made of huge stone blocks that form a concentric circle, much more magnificent than it looks from the outside.

The stone blocks are roughly rectangular in shape, standing upright above the ground and more than ten feet high.

On top of the adjacent stones, another stone lies across the top, or across two or four pieces, arranged in a peculiar pattern.

Several important positions seem to be related to the change of the planets, and are not shapes without meaning.

The stone wall is irregularly covered with strange-shaped holes, which are inlaid with precious stones, faintly emitting light.

The most striking thing is the center of the concentric circle, which is paved with a single cyan boulder.

The surface of the boulder is painted with dark golden magic symbols and complex patterns, and the whole glows with pale blue from time to time.

Each time the pale blue light flashed, a large amount of cold air was released.

Because the temperature is extremely low, these cold airs meet the surrounding air, stirring up a large amount of white mist.

Even with the protection of magic, Evan felt a chill approaching him.

He hurriedly pulled Dobby to carefully hide behind the boulders to avoid the ice mist, and when the fog was gone, he continued forward, bypassing several boulders to the core of the altar, where he saw the giant demon statue he had seen on the upper steps outside.

Before, it was separated by a wall of ice, and it was vague and unreal.

Now when I went inside, I noticed that it was a house-elf.

To be precise, it's a mutated form of a demon based on a house-elf.

The house-elf had blue skin all over, and there was no such humble, flattering smile on his face as Evan was familiar.

On the contrary, with a certain indescribable ruthlessness, the corners of his mouth showed a sneer slightly upward.

Its hands were raised slightly in a strange gesture.

Evan looked closely at the statue, and unsurprisingly, the demon that this altar could summon was this guy.

What he didn't expect was that this demon would actually be a house-elf!

I have to say that the dark wizards who built this place at the beginning have really unique tastes and hobbies.

Instead of entering the center of the concentric circles that glowed blue from time to time, Aven circled the entire altar under cover for the boulder outside.

There are signs that this demon altar has some connection to the house-elves of Hogwarts.

It appears here from time to time for no reason, and there must be some secret hidden behind it.

The stone platform used to place the sacrifices in front of the statue of Evan is carved with dense ancient magic scripts.

Not surprisingly, it should have recorded the origin of this demon and the tribute that summoned it.

These ancient scriptures are not too unpopular, but it will take time to crack them all.

He recorded the words and the magical symbols on the ground, and searched the altar carefully before leaving the place with Dobby, ready to study everything before taking his next step.

Dobby finally breathed a sigh of relief, and watched with trepidation as the cabinet filled with the blue house-elf's head returned to its place, completely blocking the entrance to the passage.

He finally came out of that horrible place below, and he vowed never to go there again.

Evan admonishes Dobby not to tell anyone about today.

An activated demon altar, if known, it won't be long before the horrors are filled with Aurors sent by the Ministry of Magic to investigate.

Before leaving the underground freezer, Evan also went to the room that had been closed by a heavy iron door.

Inside is the ancient Hogwarts water system, which is still in use today.

The room has a view of the bluestone-paved aqueducts, as well as a network of modern plumbing.

Under the influence of magic, water is brought in from the ground, passing through which it is supplied throughout the castle.

As soon as Evan and Dobby entered, they could hear the sound of water rushing by.

In the light of his wand, he noticed that the aqueduct was paved wide, and the top was connected to the main pipe of the castle.

The inlet end of the water extends all the way to the ground, and there is no end in sight in the dark.

Unexpectedly, through the water, you can see a stone staircase extending down the canal.

This shows that when the canal was first designed, it was possible for people to enter it without knowing what was hidden underneath......

Evan didn't know how the designer worked, and he wasn't interested in digging into the dark underground pipes to take a look.

After checking and finding no clues, he left with Dobby.
