Ravenclaw was secretly constructed at the tower in the Black Lake, and in the room where the three arches of the rotunda hall were connected to the blood pool, Alan Harris gently shook his slender and slightly pale fingers like a dead person, and a temporary round arched stone door filled with runes was silently closed and automatically locked.

In an environment where light is missing - forgetting to light up the lighting is a common thing for two wizards with dark vision.

Alan, whose vision was not affected by the environment, quickly moved towards the direction of the blood pool. The blue flame in the center of the blood pool made some light around it, making it extremely conspicuous in the dark environment. The humid air moistened his skin as usual, and carried an uncomfortable smell of blood. Obviously, the flesh and blood living in this special environment began to wriggle because of the arrival of the witch, and their wounds that could never heal continued to bleed out blood and tissue fluid.

Ravenclaw had been in this room for a long time. She did not change her pajamas, but was still wearing the blue gauze skirt. The corners of the skirt were flipping like waves.

Alan walked forward with a smile and found that the smell of blood was replaced by a strange fragrance. Before greeting the witch, he sucked hard in front of several metal incense burners with incense next to the other party. Then he found that the smell he had just smelled not only came from the incense burner, but from the smell of blood on the witch and the surroundings, and the mixture of the leaves of the hyenas tree and the fairy wings burning in the incense burner. Taking off the fairy's wings will not kill them, but will make them very angry with vanity.

Aware of Allen's approaching, Ravenclaw removed the Misilian stick, which had been completely eroded by shadows from the five-headed dragon bracket next to her. It was now full of magical texts learned from Netherell's scroll by Ellen himself using spells a few days ago.

"Let's talk about it after finishing it, don't get distracted." Ravenclaw said to the witch.

Alan nodded, and he found an empty incense burner from the debris around the witch, then threw a few handfuls of dragon claw powder into it and added branches of the guardian tree - a magical Yamana tree that protects those who touch its trunk from dark creatures.

After igniting them with his fingers, Alan walked towards another corner of the pentagram on the ground next to the dementor, which was not confined to any creatures, and then poured the incense ash carefully into the lines drawn with mitril silver—a disgusting smell filled the air.

Alan could feel the dragon claw powder "spiritually" his consciousness, which would make him particularly smart for the next few hours. Then he began to recite spells and began the summoning ceremony - a guy in the gate of another world who looked one bigger than the ordinary sacrificial demon was pulled out by invisible power and locked up in the barrier.

This devil full of blood - judging from the chaotic power emitted from it, the owner of these blood should be the demon in the bottomless abyss.

"Witcher, how did you know my name? What do you want?" The devil looked at the imprisonment array, and asked impatiently after realizing his situation: "Information, knowledge, or treasure? Tell me that I can finish my errands quickly. I am commanding my troops to fight bloody battles with you."

"Please wait a moment, I think we will end soon." Alan, who had had many experiences with the devil, no longer cared about the other party's terrifying evil aura. He bowed slightly to the imprisoned devil to apologize, then raised his palm, grabbed the void, and held the mysterious silver stick that seemed to be so black that it was absorbing the light around it. A dementor flew over in the imprisonment array next to him, but no matter what, it could not get rid of Alan's shackles.

The devil, who is good at writing games, realized the implicit meaning of his summoner's lines and the other party's movements, so he gave up negotiations and started rushing towards Allen - then he hit the invisible force field, made a loud noise, and was bounced back and fell to the ground.

Alan, who believed that he had strengthened the power of the imprisonment array, ignored the movement of the Demon Refining General of the Deep Demon. He waved his arm and the dementor he grabbed broke silently in an instant without making any sound. The cloak it was covered with was like the skin soaked in water, the disgusting flesh and blood, and the bones on his body were completely separated. There was no trace of carrion left on the dark and smooth bones, and it shone faintly under the blue flames in the blood pool.

Ravenclaw also came over and began to help. She used spell to remove the spine from the remaining skeleton of the dementor and removed the excess ribs, leaving only the entire curved spine.

Then the two focused on carving magic texts. With precise magic control and tacit cooperation, the dementor's spine bones were also carved with dense magic runes. After all the bones and spines were carved, Ravenclaw no longer looked at the skeleton, but turned around and approached the blood pool. Alan began to control what was now like a bone centipede and let it climb up to the black esthetic stick. When it reached the appropriate position, the bone spurs on both sides of the spine, which were densely bulging like centipede feet began to close together, wrapping the esthetic silver staff together like a comb.

Seeing Alan turn around, the devil realizes something is wrong, and it rushed over again and fails. Its resentment and malice are endless. If it is according to its wishes, it will jump up thousands of times - but Alan has used the Arcane Hand's ability to lock the devil's throat in the air and lifted it up in the air, allowing the devil to move to the edge of the imprisonment array, and then used the particularly enhanced scalpel tied around his waist to cleanly cut open the devil's skin and flesh that can withstand damage, allowing the strongly corrosive blood to flow out - under the control of Ravenclaw, these dirty, strongly acid-like liquids flowed into a characteristic huge pottery water tank.

"Wait... wait, the wizard... what do you want? Let me go, I can give you... anything." The strong desire to survive made the devil's vague mercy sound come out of his locked throat. Then it saw that the wizard was unmoved, and he said again, "You know... my lord Baier will not... let you go!"

"Ammon, who do you think gave me your name?" Ravenclaw's light voice came over, making the devil's desperate eyes widen. The witch continued to add: "Your master Bair is very similar to you. They both started from a trembling and twisting evil demon who had no intelligence. With his own tricks and hard climbs along the way, they finally promoted to the position of Demon Refining, and successfully became a devil general. Then the difference was that he was appreciated by Zariel, the Grand Duke of Aphronas of the first level of the Barto Hell, and finally launched a coup to overthrow it, and then successfully became a Devil with a unique form - and you won the attention and vigilance of your lord with your good military merits and reputation... So I and him have this cooperation, and each need it..."
