Chen Ang and Dumbledore exchanged their views on the stable method of magic. They were probably the most knowledgeable people in the entire magic world, and very few of them could compare to them. Voldemort might be one, if Nicolmay had not died, he could be one, and Gellert Grindelwald, who is now locked in Newmontaged Prison, should be one.

Even Hogwarts professors were unable to join their conversation.

At the beginning, Snape, who sat next to Chen Ang, could still listen with a gloomy face. When Chen Ang and Dumbledore talked about the role of magic texts and sound curses in the stability of magic power in the wizard bloodline and the origin of ancient magic texts in the development of modern magic spells, his face became as ugly as the dead. Further away, Professor McGonagall looked serious from beginning to end, but the incredible look she looked at Chen Ang betrayed her - she was also shocked by the unknown professor Oriental's erudition, and even a little difficult to accept.

In fact, this was also the process of Chen Ang and Dumbledore's test of each other. It was not until the students of the four colleges and Demstrong came to the hall and sat at the dining table that Dumbledore stopped with unsatisfactory and smiled: "Ladies, sirs, ghosts, and Demstrong's guests, good morning!"

"The students in the second and third grades have temporarily stopped today's class. We will start an exchange activity with the guests of Demstrong. In the next month, Professor Chen Ang will offer you a new course... a duel class with Demstrong style. Now let us welcome Professor Chen Ang!"

Harry looked at Chen Ang in surprise, and Ron, who was sitting next to him, was also stunned by the news.

He exclaimed: "It's so awesome!"

The whole Hogwarts was boiling, and Harry heard the senior Gryffindor whispering to the ears: "How is this possible?" "Is the principal crazy?" "How could Dumbledore promise such a ridiculous thing?"

Only Malfoy smiled proudly, and even cheered from Slytherin's seat.

Harry asked Ron in confusion: "What happened? Why do you all react so much?" Ron's face still couldn't hide his surprise, but with a hint of nervousness and excitement, he replied: "Dermstrong's characteristic is black magic! The duel class is actually a black magic duel class... This means that we will learn, real, lethal black magic!"

Harry didn't react, but Hermione next to him was about to jump up, and she shouted: "How can Principal Dumbledore allow such a ridiculous thing? It's illegal to teach black magic. It's simply..."

Ron hesitated: "It is illegal for the professor to be unforgivable...but most black magic is actually unlimited. Otherwise, Demstrong would not have been able to legally drive for so long! In fact, it is illegal for the professor to be unforgivable, but it is legal to let students learn by themselves and read magic books."

Hermione roared at him, "I will report it to the Ministry of Magic... If they have a little sensibility, it will stop Principal Dumbledore's crazy behavior."

At this time, cheers and applause came from Slytherin, and Demstrong's exchange students also jumped up to cheer, but the embarrassing thing was that the other three academies whispered and made a swarm-like buzzing sound. Chen Ang stood up and signaled that he had no embarrassment in the face of such a scene, but announced: "For me, everyone can learn the means to implement their will and knowledge closer to the truth."

"Many people think that I will teach you some dark, terrible knowledge, but in fact I think it's more important to teach you how to find light from the darkness, how to drive your ambitions and desires. In fact, black magic is not scary, and uncontrolled black magic is scary... I know that many of you want to be Aurors and want to be a clerk in the Ministry of Magic."

"Then you have to seize this opportunity. This is the only opportunity for you to receive a black magic education five years in advance!"

"Although it's only one month, Hogwarts' classmates will attend classes with Demstrong's classmates. You will get real training for me and learn to be a wizard's greatest and most basic ability - just like using magic to implement your will and learn how to solve the problem when the contradictions are irreconcilable."

"That's the choice between life and death."

At this time, Gidro Lohart couldn't wait to jump out and shouted: "When Professor Dumbledore asked me about the opinions of your professor in the Dark Magic Defense class, I said that I fully agree with Demstrong's proposal that you have studied at a top Dark Magic Defense Master. As long as you can learn some of my skills, the Dark Magic will be vulnerable under your hands."

"Just like I have fought with evil creatures and the dark wizards countless times...the specific details are visible in my books."

"Next I will demonstrate the etiquette and rules of duel with Professor Chen Ang for you. He told me that this will help you learn and re-understand the defense of black magic. Therefore, at his request, I will demonstrate for you how to defend against the sharp black magic... I don't want to worry about Demstrong's guests, so when my spell hits your professor - don't scream!"

Ron muttered to Harry quietly: "I don't think Dermstrong's black magic professor would be worse than Cornwall Elves."

"When our professor 'looked' him, he would not scream like a little girl!" A Dermstrong exchange student whispered to the side: "May Azathus favor him! Apart from that, I really can't think of how he can defend against the 'black magic' we taught!"

Harry also heard a communication student from Demstrong ask: "Will the professor kill him?"

"That's the best ending he can imagine!" someone replied with a sneer.

Hermione also heard it, and she turned her head to Harry and said, "How could they say that Professor Lockhart? It's so rude!" Harry felt from the bottom of his heart that Demstrong's exchange students were not too much, but he could not say anything in front of Hermione.

At this time, the senior students had finished their meal and were about to go to class. Harry and the others were asked to stay in the auditorium. When he saw Chen Ang waving his magic wand, the long dining table in the center of the auditorium disappeared, replaced by a golden stage against the wall. The magic dome above his head was clear and the sun was just right.

Professor McGonagall widened his eyes from the side - this was the first time she saw someone coming to Hogwarts, as if she had been to her own home.
