Chen ang and Lockhart bowed in opposition. Lockhart also explained: "this is the duel etiquette in the magic world. As you can see, we hold our wands to each other's chest, and then when we count to three, we will issue a magic spell to each other... Of course, children, don't be nervous. I won't hurt your professor."

"Thank Professor Lockhart for his explanation." Chen ang nodded, "I thought it was my job!"

As soon as the words fell, the exchange students of demstrom laughed loudly and without malice, and Harry and they laughed, but it was difficult to say whether the boys had subtle malice towards Lockhart.

"The formal duel between wizards has strict etiquette procedures. Before the duel, both sides should hold their wands in front of each other to show respect, or bow to each other. After that, both sides go to both ends of the field to start the duel. In a conventional duel, both sides need to use some magic to attack each other until one side loses its wand and its ability to fight back."

"But in the magic world, there is a tradition that has never been mentioned, praised and recognized by the law. When the contradiction between you and a wizard reaches an irreconcilable level, you can reach a duel that ends with the death of one party. Of course, I emphasize here - this duel is completely illegal. However, if both sides are pure blood, they will die under the honor of the family During the fight, all witnesses will keep a tacit understanding, the loser will not appeal to the magic world, and the winner will remain silent, because this is - pure blood glory! "

Slytherin and demstrom's students cheered loudly, and Malfoy shouted excitedly: "pure blood glory!"

When the other three colleges kept silent, the exchange students of Slytherin and demstrom cheered enthusiastically. Although Slytherin had no rigid requirements, almost all the students in the college were pure blood, or pure blood supporters like Voldemort, while demstrom's students must be pure blood.

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

"Here, I will show you an ancient contract Magic - duel oath..." Chen Ang's wand shook slightly, and a silver light was emitted from the top of his wand to the sky between the two dueling people.

"Duel oath is a kind of magic contract, or secret spell. As an important part of ancient magic spells, magic contract has been weakened in modern magic, but it has not disappeared. It only widely forms the basis of modern magic in the form of constituent elements in magic spells, and most of the contracts in magic spells have played a very important role."

"For example, the flying spell contains the concept of real right contract. If an item has a real right contract with others, it will be difficult for the flying spell to work if you can't get the owner's approval... That's why the flying spell can only fly its own items. Of course, if your spell level is high enough, you can use you and things when the owner approves you The contract power of the Lord establishes a temporary real right contract with the goods to attract the target goods. "

"This is an example of the widespread use of contract magic in modern magic... Another magic spell with more obvious characteristics of contract magic is famous. It is a good helper for wizards to keep secrets, the red courage loyalty spell!"

"The duel vow I'm casting now is an ancient magic spell. It was widely used in the middle ages. At that time, the magic world had not formed a perfect and reliable law and legal guarantee implementation system. Witches loved dueling. Dueling is an important way for them to deal with contradictions and solve problems. It was a dark and bloody era. Your pillow reading in your childhood - poetry urn The legend of the three brothers in the Bidou story collection has reflected this. "

"Owning the old wand, it was because he was invincible in the duel that he attracted the envy of the black wizard and finally died in a despicable murder."

"At that time, the pure blood family had not been formed, and everything was chaotic and without testimonies. Many wizards had no notaries or witnesses during the duel, and even many wizards despicably violated the oath in the duel, causing great confusion. In that era when the oath magic was still developing, someone created this magic spell - duel oath."

"Through the power of magic, the Dueler can't violate the fair duel etiquette and perform such evil deeds as sneak attack behind his back."

"Now, please let Professor Lockhart show us." Chen ang raised his wand and motioned to Lockhart.

Lohat was unable to ride the tiger, so he had to tentatively release a magic signature to the silver light above their heads. The silver light suspended above their heads exploded and turned into a pair of crossed silver * * sticks under the dome of the auditorium, indicating the success of the duel contract.

"One... Two... Three!" they waved their wands at the same time, but as soon as Lockhart made a vowel from his throat, he was hit by a green ray and petrified in place. Chen ang took back his wand, as if he was not the one who solved Lockhart as soon as the wand shook.

The professors of Hogwarts changed color one after another. Chen ang didn't even make a sound. He just made a simple gesture and sent out a strong black magic.

Seeing that Professor McGonagall opened his mouth in surprise and seemed to want to express some words of protest, Chen ang explained: "Professor Lockhart was just hit by petrified rays. I weakened the power of this magic. Professor Lockhart can recover himself in less than half an hour. Therefore, don't worry about him..." he falsely pointed to Hermione who had jumped up.

Hermione blushed with excitement and protested, "how can he do this!"

Ron rolled his eyes and muttered, "this is a duel. It's Lockhart's own useless... The result was expected." Harry kept nodding. Slytherin and Griffin's boys rarely reached a tacit understanding and burst into laughter.

Lockhart has only been here for two or three weeks, and it is a skill that makes all the boys in Hogwarts bored.

But the girls here have many of his little fans. They are still angry when they see Lockhart knocked down easily by Chen ang.

Chen ang turned a deaf ear to the following laughter and complaints. As the host and researcher of large-scale teaching and wizard blood research experiments, he really didn't care what the psychology of these experiments was. Chen ang calmly said, "who knows why Professor Lockhart has no resistance just now." Chen ang was rude to Lockhart and said directly: "And what is the first element in the magic duel?"

"It's speed!" a demstrom exchange student stood up and replied.

"Well said! Demstrom plus five points!" Chen ang smiled: "if we also participate in the College Cup..."

"Why not?" Dumbledore smiled. He stood up and waved some magic wands. A new representative college rose in the hourglass of the Hogwarts College Cup. There is no doubt that it is demstrom's points. Dumbledore smiled and said: "Hogwarts welcomes all those who come here to learn knowledge with a broad mind. We are not afraid of any competition and welcome every friend."

Chen ang nodded and continued: "yes, the first element of the magic duel is speed. When the countdown stops, who is the first to issue the magic spell, then half of the victory will step on him... Why half? Who can answer?"

It was demstrom's exchange student who stood up again: "magic reaction... Professor!"

"Magic counteraction..." Chen ang repeated. Before he said anything, Dumbledore raised his hand and laughed, "add ten for demstrom!"

"In the magic spell confrontation, defensive magic will have a protective effect on the attack magic spell, that is, only when the attack magic spell breaks through the defense of the defense spell can it have an effect, but the magic defense of the defense spell is not universal. For example, the iron armor spell has a better effect on blunt weapon strike, sharp weapon stab, weapon surrender spell and physical prank spell, but for fierce fire spell and soul snatching spell, The effect of the curse of asking for life will be much worse. It is very easy to be broken, but there are many obstacles. The curse of fierce fire is better than the curse of iron armor. "

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

"What effect will it have?"

Without waiting for someone to answer, Chen ang explained the question himself: "there will be magic counteraction, that is, before breaking through the other party's attack spell, your spell will not work, and the two will fall into a duel between magic and will until one party overwhelms the other."

"The reason for magic counteraction may be because of the exclusivity of magic, that is, in a force field, one magic cannot bypass another magic to play a role."

"Therefore, when the first factor of speed cannot play a role in the magic duel, the strength of the magic spell, which plays a decisive second factor, generally depends on the strength of the wizard's magic and has a strong relationship with willpower."

"I just defeated Professor Harold with speed... Who can tell why he was hit by my magic when Professor Harold was still chanting?" this time, even demstrom's students could not answer, because Chen ang had not taught here.

Looking at the silence below, Snape glanced coldly at the Hogwarts students and said coldly: "Professor Chen ang, these little fools may not understand the subtleties of your magic. How much can you expect from them?"

Chen ang smiled, "they just haven't learned yet."

"Spell delay..." Chen angdao: "This is the super magic skill about 'speed' in this trick. It can make you freeze a magic spell and keep it in the state of being excited. As for how long the magic spell can last, it depends on your magic, skill and the strength of the magic spell. I had completed the magic of Petrochemical ray just before the duel, so when Professor Lockhart was still chanting the spell , my spell has hit him! "

The students of demstrom and Slytherin began to stand and applaud, and Hermione was mad. If Ron hadn't pulled her, I'm afraid she would have stood up and uttered nonsense.

Chen ang motioned to everyone to calm down a little, and then said: "And the second trick - how do I prepare a black magic spell under the eyes of you and Professor Lockhart? It's about the 'secret' super magic skill... Magic tacit method. A good wizard can abandon the wand and cast magic without even using the spell. One trick is that you can use gestures instead of the wand to assist in casting magic."

"Because of the proliferation of magic wands, many wizards have lost their vigilance against the enemy's Non Stick Holders, and you can quietly complete the magic under their eyes when you are disarmed and lose your magic wand - just like I did just now."

This time, the cheers at the bottom became more intense. This time, students from other colleges cheered for Chen ang, including Ravenclaw, hutchpatch and even Gryffindor. Ron even saw his two twin brothers applauding for Chen ang.

"When I came to Hogwarts, I wouldn't teach black magic at the request of the school, but if you asked me what you could learn here, I would say - more! Dueling is a subject, an art that a wizard must master, and a knowledge that can study for a lifetime. It is strength, wisdom, courage and perseverance."

"Everyone can find what they want to learn here."

"Duel is the most basic ability of a wizard and the ultimate standard to test the level of a wizard's spell. If you pass the general wizard level test (o.w.ls), or even the ultimate wizard level (n.e.w.ts.) if you fail, you will only lose your future, but if you unfortunately fail in a wizard duel, you may lose everything. An outstanding wizard who is really different from the vulgar generation comes from their extraordinary dueling ability. This is my loyal advice to you. "

"In my class, I won't teach you how to cast magic spells and how to pronounce them. I will only take you to really understand magic and enter the world of magic. Learning knowledge and super magic skills that you haven't heard from other professors is only one and only the beginning... Next, I want to ask you, are you ready..."

"Did you enter that magical world with me?"

"I'm ready!" Malfoy stood up and said excitedly, "Professor, in Hogwarts, I saw the true meaning of magic in you for the first time. It's more shocking than anything I've learned!" At his words, the professors at Hogwarts on the stage looked ugly. Even Snape looked like a dead man, of course he always did.

Slytherin's students were a little excited. They were not liked by Dumbledore. Although they could not see it on the surface, this feeling was still obvious after the Savior came.

Ravenclaw's students are also noisy. They have the best grades and respect knowledge. Chen Ang's knowledge has convinced some of them. At least most Ravenclaw will seriously take his classes.

Gryffindor is a little schizophrenic. Some of their people who do nothing are enthusiastic about Chen Ang's promise, but Dumbledore's deep-rooted influence and Alma Mater emotion make them reject the professor from demstrom.
