The field was quiet after a lot of restlessness, and from the name of the magic that Eren wanted to teach, it was known that it was a dark creature that was summoned, which made the young wizards afraid to speak and disturb their ancient magic professor.

"Everyone knows the news in the morning, but it's not been very peaceful lately... I think you may remember some of the words I gave in front of the Temple of Ravenclaw?" Alan spoke to the young wizards in the tone of teaching ordinary magic, "I will first teach you some of the little skills of necromancy about summoning or crafting undead creatures that will be under your control forever, so that you can have some reliable guards and helpers in battle or in life." ”

Hearing Allen's words, these little wizards on the practice ground, many Muggles and half-bloods due to the influence of their childhood families, looked at those animal bones on their desks and felt a little awe, and their cognition of using necromancy to create and manipulate the bones or corpses of living things, whether the other party was an animal or a human, was not a thing worthy of praise.

No one dared to express their worries in front of Eren yet, but the thought of touching the bones of a creature they didn't know made their hearts full of awkwardness. At present, it is okay to have animal carcasses and animal bones on the table, but if the object is human...

Unlike the rest of the Weasleys, who preferred unicorn rods, Ginny, who was actually quite talented in dark magic like Hermione, didn't resist using this kind of magic to summon these dark creatures, and she didn't think much about it, and like many of the little witches present, she couldn't help but feel a little upset at the thought that she might have to deal with these corpse bones.

"Ginny," Harry took Ginny's hand and comforted him, recognizing his girlfriend's embarrassed look and retreating a little, misunderstanding the worry in the other's heart, and forcibly holding back the anger that was rising from his conversation with Dumbledore last night, and holding Ginny's hand and comforting, "You are not afraid of that ghoul in the Burrow who knocks on the sewer pipes every day, and I am much more scary than a skeleton." ”

"I'm okay Harry, I'm not afraid," Ginny explained reluctantly, "at least I don't have to touch the one at home." ”

On the other side of the practice grounds, Theodore Nott of Slytherin barked at the critter bones in front of him, "I don't know what a rabbit's skeleton can do." ”

"You really don't need a rabbit skeleton, you need a praying mantis. Draco Malfoy, who was nearby him, heard his voice and glared at him coldly, mocking.

Theodore's long neck, tilted forward slightly, looked more prominent, his face flushed with annoyance, and before he could attack, Draco Malfoy lengthened his tone, "If you want to cough again, please stay away and don't pollute the air." ”

Theodore snorted coldly and looked at Draco for a moment, then dodged his gaze and muttered, "Malfoy, I don't want to quarrel with you, but you have to think about your own identity." ”

"Actually, they are roughly divided into two ways, one is to kill the dead creatures... With your current level of mana and ability, you can transform their bones or corpses into undead skeletons or undercasters, and they will act on your commands. These undead will follow you, or stay in one of your designated areas to carry out some of your simple commands, and they will remain in this active state until they are destroyed. As if Alan didn't notice the little argument here, as if he had seen through the thoughts of these wizards, Alan picked up the textbook in front of Ginny, injected the content, and continued: " The other way is that the girls will prefer it, it is similar to the oolong out of the hole used in Draco's second-year dueling club, which allows you to pull some ready-made undead creatures directly from the underworld as helpers, the difference is that with the former method, as long as you spend enough time and energy, and the necessary materials, the undead you make are likely to be much more powerful than the ones you summoned directly. The latter is convenient, but the quality of the spell depends on whether you will be favored by Lady Luck, and unlike you make it yourself, no matter how many times you use this spell, the amount of control you can control at the same time is directly related to your current skill level. ”

Many witches were relieved to hear the magic of not having to touch bones or corpses with their own hands, and Ginny couldn't wait to look at the textbook in her hand that had just been infused with magical knowledge.

"Low-level necromantic creatures don't have intelligence, and they don't know much other than simple commands, but at least they understand that they don't know how to knock on water pipes like the ghouls raised by some of their classmates... In addition, as your necromancy skills and magic power grow, the variety and number of crafts you can craft or summon will increase, and the partners you can craft will be the same as those in front of them..."Alan finished injecting the last student's textbook and walked to the middle of the room, "Maybe you will be able to make your own Death Knight as a teaching assistant one day, but if you don't make Cetina · Ms. Warbeck's set of techniques for dealing with female ghosts when starting a female ghost choir, I don't recommend that you control female ghosts or pull out unjust spirits from tombstones, female ghosts' cries are fatal to ordinary people, and as your professor - I'm sure many people remember, I'm afraid of this kind of thing myself, of course, Helen... Ms. Gray made an exception. ”

The lines hint at reminding the young wizards that undead are actually more common than they think, and Alan jokes about his own performance in Lupin's Defence Against the Dark Arts class, and manages to put many young wizards at ease after closing the crowd into the crowd.

"So, I'm going to show you how to evoke the dead. After a brief explanation, Alan opened his fanny pack again, and placed two clay pots and a few black onyx gems next to the animal bones on each student's desk.

"In the two clay pots, one is filled with soil from the tomb, and the other is filled with salt water as a spell casting material, you can omit this part when you are skilled, and the ancient magic text that needs to be carved on the bones as an enhancement of the undead will not be explained today, but will only tell you the most basic methods today. Eren then pulled his teaching wand from his waist and waved it slowly—he broke it down and showed it to the wizards below, explaining the essentials of how to cast it.

After that, the demonstration began, and Alan used his wand to control the contents of two clay pots to mix them in the air, covering his own raven skeleton in front of him, and then picking up a black onyx and breaking it into two pieces, covering the two eye sockets of the raven's skull.

Then the wizards of the hut watched intently as Alan cast the spell with the action he had just broken down, and as he moved, a black mist came out of the mixture of grave dirt and salt water, and the gem on the raven's eye socket turned into powder, and the raven skeleton suddenly took over, and two red lights shone in the shadows of its empty eye sockets, and the two beaks of the birds closed one by one, and then flew to Alan's shoulder in the exclamation of the students.

Then, a burst of fire appeared out of thin air on the training ground of the practice class.

"Professor Harris, you can't do that. ”

Hogwarts Headmaster Dumbledore and his pet Fawkes appeared in front of everyone in an instant, and he strode over to Allen, causing his magic robe and beard to shake with his steps, "I don't agree with you teaching this kind of magic to my students. ”
