As an old saying goes, where there are people, there is struggle, and where there is struggle, there is Jianghu.

Although Hogwarts is not big, there are no more than 20 professors, but Guan Xu is very complex, and several of them are like fire and water, such as Snape and lupin, a professor of defense against the dark arts who took office this year.

If given a chance, Zhang Cheng has no doubt that they will take out their wands and give each other a vicious death spell.

In addition, the hundreds of years of struggle between the four colleges inevitably makes professors biased according to their origin and position.

Generally speaking, this school, which is known as the best magic school in Britain and even Europe, is actually full of fierce discrimination and struggle. If there were not a strong headmaster, who knows what it would be like, even if it was split and dissolved one day in the future, it would not be surprising.

As a man proficient in power, Zhang Cheng doesn\'t understand whether the four founders who were boasted to be extremely powerful had their heads kicked by a donkey or pinched by a door, and would have created such a stupid power structure.

You know, if any organization wants to grow, the most important thing is to concentrate all the forces that can be concentrated and constantly forge ahead, until it becomes a behemoth that others dare not touch easily.

To put it bluntly, it is centralization!

Temporarily suppress various factions within the organization and let everyone obey the orders of the leader.

But what did the founders of Hogwarts do?

They split the school into four different factions from the beginning, and the conceptual differences of each faction are so great that tit for tat phenomena such as Gryffindor and Slytherin appear.

Fortunately, the British magic world has not become a climate. Otherwise, if a talented and powerful wizard pops up and establishes a new magic school, Hogwarts will be defeated and replaced in a short time.

Of course, the quality of Hogwarts or the British magic world is insignificant in Zhang Cheng\'s eyes.

After the interesting opening ceremony, he closed the door again and locked himself in the room. No one knew what he was doing in it. Only occasionally, students and ghosts passing by heard strange sounds and disturbing silver lights.

Even many students believe that the newly appointed professor of magic practice is a complete freak.

The only exception is Draco Malfoy.

However, he didn\'t explain anything to anyone, just waiting for the first magic practice class with great expectation.

About two weeks later, Zhang Cheng finally walked out of the door and appeared in front of the students for the first time in a black light robe.

For teaching needs, instead of choosing a spacious auditorium and classroom, he chose to take classes on the outdoor lawn.

The object of the class was no one else. It was Slytherin college and Gryffindor college.

Looking at the atmosphere of hostility between the two sides, which was almost sparking, a playful smile appeared on his face, cleared his throat and shouted, "quiet! Maybe some of you know me, but more of you are strangers, but it doesn\'t matter. Because what I\'m going to give you next is the most intense and blood boiling battle of all courses."

"Fight... Fight?!" Hermione Granger, a three good student, couldn\'t help shouting.

Looking at the girl\'s slightly immature face, Zhang Cheng smiled and nodded: "That\'s right! Fight! Real fight! It\'s not the duel club you played last semester. In this course, you may get hurt and experience all kinds of pain and suffering, but I promise you will become strong as long as you stick to it. In addition, if someone is afraid and afraid, you can quit now. This is not a compulsory course and will not affect your final grade."

"Teach... Professor! Will you die?" Ron raised his hand and asked carefully.

"Dead? No, no, the most is the degree of bleeding and breaking a few bones. If you want to know more, you can ask Draco. He knows my teaching method very well." after that, Zhang Cheng winked at little Malfoy.

Without saying a word, the latter opened his collar and revealed a scar three centimeters long that had just healed. He sneered and defied: "see? Weasley! This is the injury I received training. If you are timid and afraid, get out as soon as possible. The professor\'s training is not prepared for waste."

"Be afraid? I\'m not afraid!" Ron retorted, blushing.

As we all know, twelve or thirteen year old children, especially boys, usually regard face as more important than anything, and even some brave people will do some dangerous and stupid things.

So when he was excited by the person he hated most, he immediately reacted subconsciously.

"Very good! I\'m looking forward to your performance. I hope you and Potter won\'t cry. As far as I know, he seems to be stunned by the Dementor on the train, right?" Draco grinned sarcastically.

But he knew how hard the actual training was, and he almost didn\'t stick to it at the beginning.

Although the intensity may decrease a lot by changing to open classes in schools, it is by no means affordable for a group of students who are well behaved.

"Malfoy, that\'s enough." Zhang Cheng resolutely stopped Draco\'s behavior.

Because he had seen that Albus Dumbledore, Jr. of Hogwarts, had stood on the high windowsill, looking down at the lawn, followed by several professors.

"As you wish, professor." little Malfoy stroked his chest with one hand and made an elegant aristocratic salute.

After solving the small conflict between the two, Zhang Cheng directly opened his arms and raised the supreme power disguised as a magic wand, instantly creating hundreds of non physical illusions composed entirely of energy on the playground.

"Oh, oh!!!!! My God!"

"Too... Too powerful!"

"Incredible!"

"Is this the strength of the professor?"

……

For a moment, every student involuntarily screamed and screamed. The scene looked very chaotic.

In contrast, Dumbledore, standing on the balcony of the castle, rarely smiled and said without looking back: "how, am I right? A wizard with this degree of spell casting ability can\'t be subordinate to anyone."

"I agree that he is a very powerful wizard, but I have reservations about whether he will contact the Dark Lord," snape replied with a gloomy face.

"Prudence is a valuable quality, but it\'s not good to be too suspicious. Don\'t worry, I don\'t feel strong ambition and desire from him. He\'s not like Tom, at least not yet."

With these meaningful words, Dumbledore turned and walked in the direction of the headmaster\'s office.

No one knows what\'s going on in his mind at the moment, and no one knows what he will do next
