Chen Ang and Lockhart bowed against each other, and Lockhart also explained: "This is the duel etiquette in the magic world. Just like what you see, we hold our wands to our chests and count to three, we will issue a spell to each other... Of course, children, don't be nervous, I will not hurt your professor."

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

As soon as the words were finished, Demstrong's exchange students laughed loudly without any malice, and Harry and the others laughed, but it is hard to say whether these boys had subtle malice towards Lockhart.

"The regular duel between wizards has strict etiquette procedures. Before the duel begins, both parties must hold the wand in front of them to show respect, or bow to each other, and then both parties will go to both ends of the field to start the duel. Both parties in the regular duel must use certain magic to attack the other party until one party loses the wand and loses the ability to fight back."

"But in the magic world, there is a tradition that has never been mentioned, nor has it been praised or recognized. When the conflict between you and a wizard reaches an irreconcilable level, you can reach a duel that will end one side. Of course, I emphasize here that this duel is completely illegal. However, if both sides are pure blood 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 magic world, and the winner will remain silent, because this is pure blood glory!"

Slytherin and Demstrong's students cheered loudly, and Malfoy shouted excitedly: "Pure-blooded glory!"

While the other three academies remained silent, Slytherin and Demstrong cheered enthusiastically and happily. Although Slytherin did not have any rigid requirements, almost all students in this academy were pure blood, or pure blood identifyers like Voldemort, while Demstrong's students must be pure blood.

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

"Here, I will demonstrate an ancient contract magic duel like everyone..." Chen Ang's magic wand shook slightly, and a silver light burst from the top of his wand to the sky above the two of them in the duel.

"The duel oath is a magic contract, or a secret spell. The magic contract, as a relatively important part of ancient spells, has faded in modern magic, but it has not disappeared. It only forms the basis of modern magic in the form of elements in the spell, and most of the contracts in the spell have played a very important effect."

"If the flying spell is a spell, it contains the concept of contract for property rights. If an item has a property rights contract with others, then if you cannot obtain the recognition of the owner, the flying spell will be difficult to play a role... This is why the flying spell can basically only fly to your own items. Of course, if your spell level is high enough, you can use the power of your contract with the owner to establish a temporary property rights contract with the item when the owner recognizes you."

"This is an example of the widespread use of contract magic in modern magic... Another spell with more obvious characteristics of contract magic is well-known. It is a good helper for wizards to keep secrets and a loyal spell!"

"The duel oath I cast now is an ancient spell. It was once widely used in the Middle Ages. At that time, the magic world had not yet formed a complete and reliable legal and legal guarantee enforcement system. Wizards like duels. Duels are an important way for them to deal with conflicts and resolve troubles. It was a dark and bloody era. The legend of the three brothers in your childhood reading poems and stories was reflected in this."

"It is because of the invincibility of the duel that the black wizard was envied by the jealousy of the black wizard and eventually died in a despicable murder."

"In that era, the pure blood family had not yet been formed, everything was chaotic and without laws. Many wizards did not have notary or witnesses during duels, and even many wizards despicablely violated their oaths in duels, causing great chaos. In that era when the magic of oaths was still developing, someone created this magic duel oath."

"Through the power of magic, the duels cannot violate the fair duel etiquette and perform evil deeds like sneak attacks behind their backs."

"Now, Professor Lockhart will demonstrate for us." Chen Ang raised his wand to signal to Lockhart.

Lockhart had to tentatively release a magic signature on the silver light above their heads. The silver light suspended above the two of them exploded, and a pair of crossed silver ** sticks formed under the dome of the auditorium, indicating that the duel contract was successfully concluded.

"One...two...three!" The two waved their wands at the same time, but Lockhart had just made a vowel from his throat and was hit by a green ray and petrified. Chen Ang took back his wand as if he had just shaken his wand and the person who solved Lockhart was not him.

The professors of Hogwarts changed color one after another. Chen Ang didn't even make a sound, but made a simple gesture and made a strong black magic.

Seeing Professor McGonagall open his mouth in surprise, as if he wanted to reveal some protests, Chen Ang explained: "Professor Lockhart was just petrified. I weakened the power of this magic. Professor Lockhart could recover by himself in less than half an hour. So, don't worry about him..." He pointed to Hermione who had jumped up.

Hermione's cheeks were flushed with excitement and kept protesting: "How could he do this!"

Ron rolled his eyes from the side and muttered, "This is a duel, Lockhart himself is useless... the result was expected." Harry next to him kept nodding, and Slytherin and Griffindo boys reached a rare tacit understanding and burst into laughter.

Lockhart had only been here for two or three weeks, and it was a skill to make Hogwarts boys bored.

But there are many of his little fans here. Seeing Lohart easily knocked down by Chen Ang, he still felt resentful.

Chen Ang turned a deaf ear to the laughter and complaints below. As the host and researcher of large-scale teaching and wizard bloodline research experiments, he really didn't care what these test pieces thought mentally. Chen Ang said calmly: "Who can know why Professor Lockhart was powerless to resist just now." Chen Ang was not polite to Lockhart and said directly: "And what is the first element in the magic duel?"

"It's speed!" a communicator with Demstrong stood up and replied.

"Well said! Demstrong added five points!" Chen Ang smiled and said, "If we also participate in the Academy Cup..."

"What's wrong?" Dumbledore laughed, he stood up and waved some magic wands, and a new representative academy rose from the hourglass of the Hogwarts Academy Cup, which was undoubtedly Demstrong's points. Dumbledore smiled and said, "Hogwarts welcomes all those who come here to learn knowledge with a broad mind. We do not fear any competition, and welcome every friend."

Chen Ang nodded and continued, "Yes, the first element of magic duel is speed. When the countdown stops, who is the first to issue a spell, then half of his foot will step on him... Why half of his? Can anyone answer?"

It was Demstrong's exchange student who stood up again: "Magic counter...Professor!"

"Magic counter-attack..." Chen Ang repeated, and before he could say anything, Dumbledore raised his hand and laughed: "Give it ten for Demstrong!"

"In spell confrontation, defensive magic will have a protective effect on attack spells, that is, only if the attack spell breaks the defense of the defensive spell, it can produce an effect. However, the magic defense of defensive spells is not universal. For example, the iron armor curse has a relatively good effect on blunt weapon strikes, sharp weapon stabbing, disarming spells and physical mischief spells. However, the effect on the sharp fire spell, soul-catching spell, and life-seeking spells will be much worse, and it is very easy to be broken, but there are many obstacles to the sharp fire spells and are better than the iron armor curse."

"But what if two wizards who duel cast attack spells on the opposing magic within the effective time at the same time?"

“What effect will it have?”

Before anyone could get up to answer, Chen Ang explained this question himself: "There will be a magic countermeasure, that is, your spell will not work until the opponent's attack spell is broken through, and the two will fall into a showdown between magic and will until one side overwhelms the other."

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

"So this creates that when the first factor of speed cannot play a role in magic duels, the strength of the second factor of the spell, which basically depends on the strength of the wizard's magic power, and is also quite related to the willpower."

"I defeated Professor Harlot with speed just now... Can anyone tell me why Professor Harlot was hit by my magic while he was still chanting the spell?" This time, even the students of Demstrong could not answer because Chen Ang had not yet taught here.

Looking at the silence below, Snape glanced at the Hogwarts student coldly and said in a cold tone: "Professor Chen Ang, these little idiots may not understand the subtleties of your magic. How much expectation can you repay them?"

Chen Ang smiled and said, "They just haven't learned it yet."

"Spell delay..." Chen Ang said: "This is the super magic trick about 'speed' in this trick. It can allow you to condense a spell without firing and keep it in the state that is about to be activated. As for how long the spell can last, it depends on your magic, skills and the strength of the spell. I had already completed the petrified ray magic before the duel began, so when Professor Lohart was still chanting the spell, my spell had already hit him!"

The students of Demstrong and Slytherin began to stand up and applaud, and Hermione was so angry that if Ron hadn't pulled her, she would have stood up and spoken loudly.

Chen Ang signaled everyone to calm down for a little while, and then said, "And the second trick, how did I prepare a black magic spell under the noses of you and Professor Lockhart. It was a super magic trick about the 'secret'... Spell Silence, a clever wizard can abandon the wand, and even cast magic without using the spell. One trick is that you can use gestures instead of the wand to assist in casting."

"Because of the overflow of magic wands, many wizards have lost their vigilance against their enemies' non-staffed hands, and you can quietly complete magic under their noses, and when you are disarmed and lost your wand, just like I did just now."

This time the cheers below became even more enthusiastic. This time, students from other academy began to cheer for Chen Ang, including Ravenclaw, Hufflepuff and even Gryffindor. Ron even saw his two twin brothers applauding Chen Ang.

"I came to Hogwarts. I won't teach black magic out of the school's request, but if you ask me what you can learn here, I'll say too much! Duel is a lesson, an art that a wizard must master, a knowledge that can study for a lifetime, it is strength, wisdom, courage, and perseverance."

“Everyone can find what they want to learn here.”

"Dull is the most basic ability of a wizard, and it is the ultimate standard for testing a wizard's spell level. If your universal wizard level test (o.w.ls) and even the ultimate wizard level (n.e.w.ts.) fail, you will only lose your future, but if you unfortunately fail in a wizard duel, you will likely lose everything. An outstanding wizard who truly distinguishes himself from vulgar people all comes from their extraordinary duel ability. This is my advice to you."

"In my class, I will not teach you how to cast spells and how to pronounce spells. I will only take you to truly understand magic and enter the world of magic. Learning the knowledge you have never heard of in other professors, super magic skills, is just one of them, just a beginning... Next I will ask you, you are ready..."

"Have you entered that magical world with me?"

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

The students of Slytherin were a little excited. They were not favored by Dumbledore. Although they could not be seen on the surface, the feeling was still somewhat obvious after the Savior came.

The students of Lavenclaw were also a little noisy. They had the best grades and praised knowledge. Chen Ang's knowledge impressed some of the higher ones, and at least most of Lavenclaw would take his class seriously.
