As if burned by that murderous gaze, Dolfin Rohr shrank for a moment and muttered, "Master, I..."

"Pull seven mudbloods and drain their blood. Voldemort was not interested or patient to listen to his explanation, "If our "coins" do not satisfy the devil, we will use you to make up for it..."

"Yes, master. Hearing this, Dorfin did not dare to say another word begging for mercy, he walked into the midst of the Muggles who had been frozen in fright, and with a trembling wand, he selected seven male Muggles who looked relatively strong, and shot a sharp blade to jump and cut the Muggles' wrists.

The seven Muggles tried to scream but couldn't make a sound, tried to cover their wrists but couldn't move. Compared to the pain in their wrists, what scares them the most is that they seem to feel every drop of their blood flowing from their wrists, and these blood gushes out strongly and weakly with their thoughts, and drips to the ground...

The gurgling blood slowly converged towards the altar in the middle of the room as if it were alive, and the red blood flowing up against the river seemed to be shrouded in a faint silver light, forming a six-pointed star array similar to the five-pointed star-shaped confinement circle in the tower in the room, and each corner of the six-pointed star array was piled up like a pyramid, and these white skulls were painted with runes drawn by the purgatory, and the empty eyes, nose, and mouth were facing the middle of the star array.

"It's too slow, Dolfin. Voldemort's slender fingers fiddled with his wand carelessly, but Dolfin was not careless and waved his wand repeatedly, hastening the blood loss of the injured Muggles.

Clearly perceiving this change in speed, an irrepressible fear tormented these Muggles. With a thud, a female Muggle fell to the ground first, and shortly after, a chubby middle-aged male Muggle also fell to the ground. One by one, the Muggles, whose wrists had been severed and powerless in the face of the approaching death, fell to the ground, their wide, dilated pupils staring desperately at the gray stone ceiling above their heads, until the world before them turned completely dark.

In fact, the ritual required only six adult human blood, but Voldemort replaced the devil's superstitious numbers with his own superstitious ones, which resulted in a muggle weight of blood being wasted and flowing helplessly beneath the altar.

Voldemort, who was originally dismissive of summoning magic and illusion magic, and only believed in more direct, simple and crude magical powers, changed his attitude towards magic after the Ministry of Magic fought with Allen, in addition to asking his subordinates to collect knowledge related to illusion magic for him, he also launched his Death Eaters to search for ways to summon devils, and even sent people to track down the Greek wizard who was invited by the Ministry of Magic to summon the devil Byer, but the result still did not satisfy him.

Because the few Greek wizards who the Death Eaters had worked so hard to find were actually controlled by the Imperius Curse, they didn't know anything about how they summoned a devilish archduke like Beyer.

The knowledge of summoning demons provided by the Death Eaters was either a few words within their family, far less detailed than the detailed records of the Black family, which had a style of death, or even a few country legends. Only Bellatrix Lestrange took a few people to sneak back to England in person, and obtained the knowledge of the magic of the otherworldly oath that Alan had provided them with from the English Aurors. And in order to prevent the Aurors from detecting an accident in the health of their wearer and notifying the other Aurors to come and expose the attack, the horrible Death Eaters even suppressed their desire to kill, and asked Lockhart to put the finishing touches on the Oblivion Charm, which he excelled in.

However, due to the fact that the spell itself can only summon some low-level otherworldly creatures, and when summoning to determine the type, it is necessary to have a certain understanding of the name and habit form of the summoned object, so the Aurors only have the low-level devil Cerberus information provided by Allen, so this spell is not even a chicken rib for Voldemort himself, and these low-level creatures cannot participate in a battle at their level.

Of course, in the spirit of making the best use of things, Voldemort let his men try to learn this spell - Although most of the Death Eaters' camps have nothing to do with order and are chaotic and evil guys, it is much more difficult for them to fight their wills after summoning Cerberus than the Aurors, and as a result, some Death Eaters with low combat power and insufficient talent are bitten to death by the Cerberus they summon when they use this spell, but after all, elite members like Uncle Lestrange and Lucius are still very safe to use this summoning spell.

Although the other countries looking for different ways of summoning demons are different, they cannot escape the traditional mode of sacrificial ritual magic used by traditional shamans.

Compared to the magical knowledge that Bayer provided to Eren in the Goblet of Fire tournament for his own use, the traditional summoning method of this type of wizard is extremely troublesome from the beginning of the preparation, and the general wizards provide the devils with rare magical materials, or some magical creatures or even a large amount of gold as sacrifices.

Although the devils themselves have no interest in gold, they have found that many mortals are willing to sell their souls for such small things when they are "doing business", so they are now very willing to exchange something for a large amount of gold as a reserve in business.

Of course, it would be rude and certainly dangerous for some Barkeys who didn't know anything to pay their bills with silver coins, which the devil and demons alike called poison stings, because although silver magic weapons would inflict additional damage on these lower plane creatures, at least quite a few of them. Ordinary silver items don't have this effect, but obviously, they can still sting - if you're dealing with a devil who might let you go because of their greed for closing the deal, or even kindly explain everything to you and ask you to change the equivalent currency to pay the bill, but if you do it to a demon who is constantly changing his ways to get into trouble......

At this time, Voldemort obviously did not have the patience and willingness to use what he thought was more troublesome and costly - he did not want the funds in his Death Eater families to be wasted on something that could be replaced by worthless mudbloods, so the mysterious man who could only learn the name and form of Byer from the old news of the Goblet of Fire took the summoning method that was in line with his status as a dark wizard, that is, the living sacrifice.

Living sacrifices were a way to give the lives of intelligent beings in return from the devil or demons, and were required by the gods to perform such rituals on a regular basis in the days when the ancient gods were not buried with Nethriel's mad magical experiments. To this day, in the traditional wizarding culture of some Native American wizards, there are still such bloody magical rituals in the primitive magic that has been preserved - but the objects of sacrifice of these Indian wizards are their own ancestors, and the Magical Congress of the United States, which is a European wizarding civilization in its bones, has long ordered to prohibit the barbaric behavior of these Native people, at least on the surface.

Most demons and demons accept this form of sacrifice - it means killing sapient beings alive, and the victims are generally human, but the dark forces are generally not picky about whether the sacrifice is a giant or a mermaid or some ghost.

In many of these ceremonies, blood is seen as a sacred symbol of life. The blood that flowed from the innocent sacrifice, and even his soul would be taken as part of the sacrifice. Bloodless rituals, such as strangulation or drowning, can also be part of a living sacrifice, but more often than not, the cruel ones prefer to see the blood of the sacrifice, although it is not actually necessary.

Voldemort was clearly the most brutal of these creatures, and he chose this dark way to satisfy his personal habits, mobilizing the Death Eaters to hunt Muggles everywhere at the risk of being captured by the Aurors around the world - and in order to have the time and place to collect enough Muggles, he used his golden gallons to set up a secret base in uncontrolled Albania.

Before accumulating a sufficient number, the Death Eaters had to keep the Muggles they had captured first in cages, and during this time, many Muggles died due to the rapid weakening of their bodies due to lack of care, and some died directly from the abuse of their Death Eaters for pure fun, so the dark wizards had to keep catching Muggles to replenish them.

Therefore, after the altar had been set up and the mysterious man who had learned to master the ritual magic estimated that the amount of Muggle storage was almost sufficient, he immediately chose to start the ritual.

Compared to the magic circle that could be recycled in the confinement room of the Ravenclaw Tower, the circle used in this living sacrifice was only a disposable.

Magic circles made of Muggle blood are temporary, far less stable than those drawn by Mithril with good magic conductivity, and not only the materials, but also the magic patterns they present, and the details of the lines drawn by Mithril by Rowena Ravenclaw, who had read the Nesser Scrolls, are more complex and the magic they can contain is more powerful - although the effect of this circle is enough if you just want to make a deal with the Devil Archduke.

Seeing that the grooves carved in the ground circle refused to absorb more blood, Voldemort's slender spider-like fingers clenched his wand, pointing at the six-pointed star array where the blood was converging, his lips did not move, and the words full of order and evil seemed to come from his two slender nostrils, but this sound was not heard, but acted on the heart.

The Death Eaters in the halls found a feeling of dizziness and weakness pervading their bodies. Gilderoy Lockhart even felt trembling all over his body, and his eyes widened in paleness and horror.

Unlike the reluctant support of wizards, Muggles have no magic in their bodies at all, and it is even more painful for them to face this feeling, a violent pulling sensation acting on their souls and bodies, as if their souls are being pulled out of the top of their heads little by little, this severe pain that directly acts on the soul, so that all Muggles are directly paralyzed in place, and they can't even blink their eyes.

The young man who had been the first to open the door of the cage was the first to lose his support, and fell to the ground in convulsions, his big foot weakly kicking the boulder floor a few times, his face distorted and stopped breathing, and then his soulless body turned into powder and dissipated into the air of the hall

This kind of blasphemy has nothing to do with the physical strength of Muggles, because it directly affects the soul, so even if they look strong Muggles, if their souls are weak, they will fall to the ground and die first than those old and weak women and children with strong souls.

And as Voldemort chanted incantations for a long time, and every Muggle fell to the ground and died and dissipated, a skull covered in purgatory language absorbed a soul. As the thirty-six Muggles fell to the ground one after another and lost their lives, the thirty-six skeletons piled up on the six-pointed star array were all ignited by their souls one by one, and the soul fire jumped in the skeletons' hollow eye sockets.

In the center of the six-pointed star array drawn by blood, a huge circular pool of blood faintly appeared, and the blood that gathered in the pool of blood rolled and tumbled, one after another blood bubbles bulged and burst, the unpleasant and pungent smell of sulfur gradually became stronger, and the hot breath continued to spread in the air.

Suddenly, goat-like horns emerged from under the tumbling pool of blood in the middle of the six-pointed star array, and it slowly rose, its burning, steaming flame mane imposing.

Black venom continued to drip from the monster's mouth, and its burning yellow eyes circled the hall, freezing on Voldemort, who had stopped chanting the incantation.

Gradually, the almost four-meter-tall Devil Grand Duke was revealed in the hall, with long, powerful arms, a flaming whip in his left hand, a long sword filled with lightning in his right hand, bat-like wings on its back, a wailing human head wrapped around its waist, and three silver-white skulls running through its tail.

"Lord Dark Lord, times have changed, why do you have to call me here in such a wasteful way?" said Beyer in his slightly flirtatious, exotic tone, half-jokingly, half-grumbling, "I'm not one of the perverts of the bottomless abyss, and our devil's reputation is largely ruined by your useless and resource-wasting ways... Coupled with the brain-dead behavior of the young people in the band who sing noisy music in the United States, it makes our business more and more difficult..."
