Chen Ang and Lockhart bowed opposite each other, and Lockhart explained, "This is the duel etiquette of the wizarding world, as you can see, we raise our wands to each other's chests, and when we count to three, we will cast a spell on each other...... Of course, kids, don't be nervous, I'm not going to hurt your professor. ”

"Thank you, Professor Lockhart, for your explanation." Chen Ang nodded and said, "I thought this was my job!" ”

As soon as he finished saying this, Durmstrang's exchange students laughed loudly and without malice, and Harry and the others laughed too, but it was difficult to say whether these boys had subtle malice towards Lockhart.

"Formal duels between wizards have strict ceremonial procedures, and the duel begins with both sides raising their wands in front of them in respect, or bowing to each other, after which they go to each end of the arena to begin the duel. In a regular duel, both sides use a certain amount of magic to attack each other until one loses their wand and loses the ability to fight back. ”

"But in the wizarding world, there is a tradition that has never been mentioned, sanctioned or acknowledged by the law, that when you and a wizard have reached an irreconcilable point of conflict, you can enter into a duel that ends in the death of one of you, and of course, I emphasize here - such a duel is completely illegal. However, if both parties are pure-bloods and fight to the death under the honor of the family, all witnesses will maintain a tacit understanding, the loser will not appeal to the wizarding world, and the winner will remain silent, because this is - pure-blood glory! ”

The Slytherin and Durmstrang students cheered loudly, and Malfoy shouted excitedly, "Pure-blood glory!" ”

While the other three houses were silent, the exchange students of Slytherin and Durmstrang cheered enthusiastically and happily, although Slytherin did not have a hard and fast requirement, almost all the students in this house were pure-bloods, or pure-bloods like Voldemort, and Durmstrang students had to be pure-bloods.

The Hogwarts professors were silent, obviously uncomfortable with this sensitive topic.

"Here, I will demonstrate to you an ancient contract magic - Duel Oath ......" Chen Ang's wand flicked slightly, and a silver light was launched from the tip of his wand into the sky between the two dueling people.

"The dueling oath is a kind of magic contract, or - secrecy spell, magic contract, as a more important part of ancient spells, has been diluted in modern magic, but it has not disappeared, but in the form of the constituent elements of spells, it has widely formed the basis of modern magic, and most of the contracts in spells have played a very important role."

"If an item has a property contract with someone else, then if you can't get the approval of the owner, it will be difficult for the Flying Charm to work...... Of course, if your spell level is high enough, you can use the power of the contract between you and the owner to establish a temporary property contract with the object and attract the target item. ”

"This is an example of how contract magic is widely used in modern magic...... Another spell with more obvious characteristics of contract magic is famous, it is a good helper for wizards to keep secrets, the Loyalty Charm! ”

"The dueling oath I cast now is an ancient spell, it was widely used in the Middle Ages, when the wizarding world did not yet form a perfect and reliable system of law and legal guarantee enforcement, wizards love duels, duels are an important way for them to deal with conflicts and solve troubles, it was a dark and bloody time, your childhood pillow book - the legend of the three brothers in the collection of poems and beans has been reflected in this."

"Possessing the Elder Wand, it is because of his invincibility in duel that he attracted the jealousy of the dark wizard, and finally died in a despicable murder."

"At that time, the pure-blood family had not yet been formed, everything was chaotic, there was no law, many wizards had no notaries and witnesses when dueling, and there were even many wizards who vilely violated their oath in the duel, causing a lot of confusion, and in that era when the magic of the oath was still developing, someone created this spell - the dueling oath."

"Through the power of magic, it is impossible for duelists to violate fair dueling etiquette and perform evil deeds such as sneak attacks from behind."

"Now, Professor Lockhart will be invited to demonstrate this for us." Chen Ang raised his wand and gestured to Lockhart.

Lockhart had no choice but to tentatively release a magic signature on the silver light above their heads, and the silver light suspended above the two of them exploded, conjuring a pair of crossed silver ** staff under the dome of the auditorium, signaling that the duel contract was successfully concluded.

"One...... Two...... Three! Both waved their wands at the same time, but Lockhart had just made a vowel sound from his throat when he was hit by a green ray, petrifying in place. Chen Ang withdrew his wand as if it was not him who had just flicked his wand and had dealt with Lockhart.

The professors at Hogwarts changed color one after another, and Chen Ang didn't even make a sound, just made a simple gesture, and emitted a shot of black magic that was not weak.

Seeing Professor McGonagall's mouth open in surprise, as if she wanted to confide in some words of protest, Chen Ang explained, "Professor Lockhart was only hit by the petrification ray, I weakened the power of this magic, and it won't take half an hour for Professor Lockhart to recover on his own." So, don't worry about him......" He gestured to Hermione, who was already jumping.

Hermione's cheeks flushed with excitement, and she kept protesting, "How can he do this!" ”

Ron rolled his eyes beside him and muttered, "This is a duel, it's Lockhart himself useless...... The results were expected. Harry nodded his head as Slytherin and the Gryffindor boys reached a rare tacit understanding, letting out a burst of laughter.

Lockhart has only been here for two or three weeks, and he has made everyone at Hogwarts bored with it, which can be regarded as a kind of ability.

But there are many girls here who are his little fans, and they are still resentful when they see Lockhart being easily knocked down by Chen Ang.

Chen Ang turned a deaf ear to the laughter and complaints below, as the host and researcher of the large-scale teaching and wizard bloodline research experiments, he really didn't care what these experiments were thinking, Chen Ang said calmly: "Who can know why Professor Lockhart didn't have the power to resist just now. Chen Ang was unceremonious to Lockhart and said directly: "And what is the first element in a magic duel?" ”

"It's speed!" The exchange student with Durmstrong stood up and replied.

"Well said! Durmstrang adds five points! Chen Ang smiled: "If we also participate in the Academy Cup......

"Why not?" Dumbledore laughed, he stood up and waved some wands, and a new representative house rose from the hourglass of the Hogwarts House Cup, no doubt it was Durmstrang points. Dumbledore smiled and said, "Hogwarts welcomes everyone who comes here to learn with a big heart, and we are not afraid of any competition, and we welcome every friend." ”

Chen Ang nodded and continued: "That's right, the first element of a magic duel is speed, when the countdown stops, whoever is the first to cast a spell will be half a foot in victory...... Why half one? Can anyone answer? ”

It was Durmstrang again, and the exchange student stood up: "Magic countermeasures...... Professor! ”

"Magic countermeasures......" Chen Ang repeated, and before he could say anything, Dumbledore raised his hand and laughed, "Ten points for Durmstralong!" ”

"In the spell confrontation, the defensive magic will have a protective effect on the attack spell, that is, only the attack spell can break the defense of the defense spell to produce an effect, but the magic defense of the defensive spell is not universal, for example, the iron armor spell has a better effect on blunt weapon strikes, sharp weapon stabs, and disarming spells and physical mischief spells, but for the fire spell, the soul snatching spell, and the life spell, the effect will be much worse, and it is very easy to be broken, but the obstacles are better than the iron armor curse."

"But what if two dueling wizards cast an attack spell on the opponent at the same time within the effective time?"

"What will happen?"

Chen Ang didn't wait for anyone to get up and answer, so he explained the problem himself: "There will be a magic counter, which means that until you break through the opponent's attack spell, your spell will not work, and the two will fall into a duel of magic and will, until one side overwhelms the other." ”

"The reason for the magic counteract may be because of the exclusivity of magic power, that is, in one force field, one magic force cannot bypass another magic force to work."

"So this leads to the fact that in a magic duel, when the first factor of speed cannot play a role, the strength of the spell that plays a decisive role - depends roughly on the strength of the wizard's magic, and it is also quite related to willpower."

"I just beat Professor Harlot with speed...... Can anyone tell why Professor Harlot was struck by my magic while he was still chanting spells? This time, even Durmstrang students couldn't answer, because Chen Ang hadn't taught it yet.

Seeing the silence below, Snape glanced coldly at the Hogwarts students, and said in a cold tone: "Professor Chen Ang, these little fools may not be able to understand the subtleties of your magic, how much more can you expect from them?" ”

Chen Ang smiled: "They just haven't learned yet. ”

"Spell Delay......" Chen Ang said: "This is the super magic technique of 'speed' in this trick, it can allow you to condense a spell without emitting it, and keep it in a state that is about to be activated, as for how long the spell can last, it depends on your magic power, skill and the strength of the spell, just before the duel starts, I have already completed the magic of petrifying rays, so when Professor Lockhart is still chanting the spell, my spell has already hit him!" ”

The Durmstrang and Slytherin students gave a standing ovation, and Hermione was mad, if it weren't for Ron pulling her, she would have gotten up and lashed.

Chen Ang motioned for everyone to calm down a bit, and then said, "And the second trick—how did I prepare a dark magic spell under the noses of you and Professor Lockhart. That's about 'stealth' supermagic tricks...... Spell Silence, a skilled wizard is able to drop his wand and cast magic without even using a spell. One trick is that you can use gestures instead of wands to aid in spellcasting. ”

"Because of the proliferation of wands, many wizards have lost their vigilance against the non-wands of their enemies, and you can quietly do magic right under their noses, when you're disarmed and lose your wand—just like I just did."

This time the cheers were even louder, and this time there were students from other houses cheering for Aang, including Ravenclaw, Hufflepuff and even Gryffindor, and Ron even saw his two twin brothers applauding Aang.

"I'm coming to Hogwarts and I don't teach dark arts because of the school's requirements, but if you ask me what you can learn here, I'd say - more! Duel is a lesson, an art that a wizard must master, a knowledge that can be studied for a lifetime, it is strength, it is wisdom, it is courage, it is perseverance. ”

"Everyone can find something to learn here."

"Duel is the most basic ability of a wizard and is the ultimate test of a wizard's spell level, if your universal wizard level exam (. LS), and even the ultimate wizard level (.. Fail, you'll only lose your future, but if you're unlucky enough to lose a wizarding duel, you'll risk losing everything. A truly outstanding wizard who is distinguished from the vulgar is due to their extraordinary dueling ability, and this is my advice to you. ”

"In my class, I won't teach you how to cast spells or how to pronounce spells, I'll only take you to really understand magic and enter the world of magic. Learning the knowledge that you have not heard of in other professors, the skills of supermagic, is only one thing, and it is only the beginning...... I'm going to ask you, are you ready......"

"Have you entered that magical world with me?"

"I'm ready!" Malfoy stood up, and he exclaimed, "Professor, for the first time at Hogwarts, I saw the true meaning of magic in you, and it was more shocking than anything I had ever studied!" Hearing his words, the faces of the Hogwarts professors on the stage turned ugly, even Snape looked like a dead man, of course he always did.

The Slytherin students were a little excited, they were not treated well by Dumbledore, although it was not obvious on the surface, but after the arrival of the Savior, this feeling was still somewhat palpable.

The Ravenclaw students were also a bit noisy, they had the best grades, they admired knowledge, and Chen Ang's knowledge impressed some of the people in the upper ranks, at least most of the Ravenclaws would take his classes seriously.

Gryffindor was a little schizophrenic, and some of their no-nonsense people were enthusiastic about Chen Ang's promises, but Dumbledore's deep-seated influence and alma mater affection made them somewhat repulsive to the Durmstrang professor.
