Since the beginning of this term, Dumbledore has been very pleased with the progress of Hogwarts School of Witchcraft and Wizardry, and all aspects of the school have made great progress.

In the past six months, due to Hogwarts School of Witchcraft and Wizardry's exclusive monopoly on the trade of magical raw materials between the East and the West in the United Kingdom, and then reached a price alliance with Beauxbatons School of Witchcraft and Wizardry, the school's financial income has grown exponentially.

Moreover, this project belongs to the school's own operation, self-finance, and is free from the supervision of the school board, making it much easier for Dumbledore to spend money. As a result, Dumbledore has been tougher against the school board lately.

The school board was outraged.

On the one hand, Zhang Xu showed through the students of the Snake Academy who came to test that these projects were based on Dumbledore's character and strength, and cooperated with Dumbledore, and the Huaxia side only recognized Dumbledore and not others. As for whether Dumbledore kept the project at Hogwarts School of Witchcraft and Wizardry or in his own hands, it was his own business. The cooperation with Beauxbatons School of Witchcraft and Wizardry is to cooperate with Nicol Lemay under the guise of Dumbledore. If you have someone in your family who can compare to Dumbledore and Nicol Lemay, you can talk about cooperation.

On the other hand, nearly two-thirds of the members of the school board were second-tier agents of Hogwarts, and Dumbledore had left them with enough profits that they were reluctant to lose the fat.

In the end, the directors of the school board were all concerned about handing over Hogwarts School of Witchcraft and Wizardry to Dumbledore, except for Malfoy Sr., who was often troublesome, and the other directors were basically quietly transparent.

Since the beginning of this semester, driven by the new knowledge brought by Zhang Xu, Hogwarts students have been enthusiastic about learning.

Although the learning boom brought about by this trend will gradually weaken, its impact will still affect the students' future study and life.

What satisfied Dumbledore the most was that the students of the various houses began to break the restrictions of the houses on a large scale and communicate with each other and learn from each other.

There is a competitive relationship between the four Hogwarts houses, and the exchange of students between the various houses is more of a small number of individual friends helping each other and interacting for the purpose of marriage, and academic exchanges are even less common. With the exception of Quidditch against the House of Serpents, for example, it is rare for more than two houses to come together.

However, Zhang Xu's appearance once again stirred up the pool.

The opportunity for change was Zhang Xu's reading room.

In the reading room, Zhang Xu created a relaxed environment and divided a corner for students to discuss with each other.

At first, Zhang Xu was just there to discuss some issues with the students of various colleges.

In the reading room, Zhang Xu's identity makes it easy for students from other colleges to ignore his identity as an academy. For Zhang Xu, who was arrested to make up classes before going abroad and communicated with the professors in advance after coming to Hogwarts, some of the students' questions can be answered, and the other part can only answer an idea, and then introduce them to which professor to go to.

Gradually, Zhang Xu silently recorded the information of the students he had discussed, which students were good at what and which students were not good at.

Next, Zhang Xu began to guide the students to communicate with each other. For example, the students of this lion academy asked Zhang Xu a question, Zhang Xu deliberately said no, and then used a thousand paper cranes to call students from other colleges in the reading room who could answer this question to help answer the question. The students who were called would naturally give Zhang Xu a face, and they themselves realized that there might be times when they would find someone to help like this in the future, so most of the students were happy to help with this.

When many students were accustomed to researching and discussing problems with students from other colleges, Zhang Xu played the next card.

Zhang Xu asked the professors to help him get a piece of enchanted parchment and hang it in the reading room, and the students wrote down any questions they had, and then counted the most problems in the last three days, and finally held a special seminar salon every three days in the reading room.

Hogwarts students are new to the salon where students from different houses sit together and discuss an issue. After participating in several times, everyone is very satisfied with such a salon.

Everyone found that in such an environment, everyone studied and discussed problems together, not only "you have one thought, I have one thought, exchange with each other, we all have two thoughts, or even more", but also find a girlfriend more easily.

At Hogwarts, students don't get many opportunities to be in the limelight, with the vast majority of students rarely getting a chance to be in the limelight except for Quidditch matches. Now there is a new opportunity to be in front of everyone, especially after a classmate of the Eagle Courtyard attracted a girl from the Lion Courtyard to hook up, a group of single dogs flocked to this salon. Of course, if you want to be in the limelight, you must first have that level, and if you are slapped in the face in turn, then it will become a joke. After Anthony Goldstein told Zhang Xu about this, he embarrassed Zhang Xu on the outside and on the inside.

Zhang Xu's hand arrangement showed its power after the Halloween troll incident.

A few days after Halloween, Zhang Xu came to the principal's office with a proposal for the Hogwarts School of Witchcraft and Wizardry's campus broadcast system.

The proposal uses the fact that Hermione did not receive an emergency evacuation notice on Halloween night, and explains the importance of hanging loudspeakers throughout Hogwarts Castle.

Moreover, this system is not complicated, most of the content can be used by students to research and construct, and the principal and professors are only responsible for the core authority settings and other content. The school only needs to pay for the cost of materials, and the labor cost can be paid to the students participating in the project with the credit of the college.

This plan to exploit students to death was supported by Dumbledore, and then the headmaster signed an order for Zhang Xu to lead the construction of the project.

The next day, Hogwarts School of Witchcraft and Wizardry's Campus Broadcasting System Engineering Department was set up in the reading room.

At the same time, Zhang Xu, the project manager, hung up an overview of the Hogwarts School of Witchcraft and Wizardry's campus broadcasting system project and a recruitment notice for the members of the project department in the reading room.

The recruitment notice announced the job requirements of the deputy manager of the project department, the technical person in charge of the project, the construction worker, the safety officer, the material officer, the quality inspector and the data clerk recruited by the project department, and required each recruiter to form their own team and then apply in the name of the team leader.

Zhang Xu's parents in the last life were engaged in engineering, and he was an IT dog in a room of construction site dogs during the Spring Festival reunion dinner.

In the face of such a novelty, the whole of Hogwarts boiled.

Although they have to bring their own dry food to work for nothing, and the remuneration is only the college points that can be seen but not eaten, many ambitious senior students are eager to try, and they begin to call friends to form their own teams and prepare application materials according to the requirements of the recruitment notice.

Since the college points as remuneration are issued according to the position, how to distribute the post team within the team is a matter within the team, and finally everyone is assigned to report on the line, so the formation of the team is very much to test the level of the school organizer.

Due to the fact that the seminar salon organized by Zhang Xu was very lively before, many organizers were very clear about the characteristics of the top students from other colleges, and with Zhang Xu and Dumbledore and other professors secretly guiding, cross-college groups became a general trend.

A week later, at the job fair on the weekend, Zhang Xu, as the project manager, and Professor McGonagall, the representative of Party A, presided over it together. After two days of work, the ownership of each position was determined.

The most notable of these are the Weasley twin brothers, who have joined the team of project technical leaders and construction workers through their familiarity with Hogwarts Castle.

A little over a month later, two days before the Christmas break, the Hogwarts School of Witchcraft and Wizardry campus public address system was completed and put into use.

Faced with Hogwarts, whose painting style has become more and more weird, the initiator Zhang Xu can only look at the sky in embarrassment.

In the opinion of Dumbledore and other professors, the construction of the loudspeaker system this time, the role of the loudspeaker system itself is secondary, and the biggest gain is that the invisible wall between the four houses is beginning to be broken.

If Zhang Xu knew that the mass basis for the students of the four academies to come to him to ask about the gossip that day came from the loudspeaker system he had made, he didn't know whether to cry or laugh.

Later, when Zhang Xu wanted to build an ice and snow waterfront garden by the lake, he set up the Hogwarts School of Witchcraft and Wizardry Ice and Snow Waterfront Garden Project Department, and pulled a group of people to work together. By this time, students were already very familiar with cross-faculty collaboration.

After such a series of events, the invisible wall between the four houses of Hogwarts was further broken, and for a while, the student halls of the entire school were divided into eagles, lions, snakes, badgers, and people, regardless of high and low grades, and they were all in harmony.

Except for the Harry Potter Audio-Technica and the Malfoy Trio.

"Malfoy and Potter, they quarreled again today." At a round table in the waterfront garden, a girl from the Badger House looked at the Harry Potter Triangle and the Malfoy trio in the distance, and said to a girl from the Snake Courtyard sitting nearby.

"Actually, Malfoy usually mentions Potter, and usually one of Malfoy's three sentences mentions Potter." The girl from the snake courtyard said.

"Then how did they get on such a bad relationship?" The badger girl was surprised.

"I've heard Granger say that on the first day of the train to Hogwarts, Potter met Ron Weasley, and the two of them hit it off at first sight. Later, Malfoy found Potter in a hurry, and was eager to befriend Potter. But Malfoy's attitude was very bad, and he angered Potter at the time. From that time on, Potter was disgusted with Malfoy, and Malfoy began to sneer at Potter and them, especially Ron Weasley. A girl from the lion house said to several girls in a tone of "I will tell you quietly, don't tell others".

"If Malfoy wants to be friends with Potter, why do this to him?" The girls in the badger courtyard said hello with a look on their faces.

"I've heard people say that Malfoy's personality is called tsundere." The girl from the Eagle Courtyard on the side said, "In order to hide their shyness, people with this kind of personality make tough and arrogant words and deeds. Think about it, is Malfoy that kind of character? ”

Several girls drinking afternoon tea together at the round table thought for a while, and suddenly their collective eyes lit up, as if they had opened the door to a new world together.

Malfoy always wanted to reconcile with Potter, but he was inconsistent, couldn't pull his head, used a tough attitude to hide his shyness, and often said the wrong thing when he was stupid...... Let's ......."

'Malfoy is really ...... for Potter Let's ......."

Malfoy was angry that Weasley had snatched his Potter...... Let's ......."

"Weasley is a childhood sweetheart, Malfoy is a heavenly descendant, and the heavenly descending line is destined to defeat the childhood sweetheart...... Let's ......."

A few days later, Zhang Xu, who heard the gossip, choked on his lungs with a sip of tea, and when he tried to go to Madam Pomfrey to get some medicine, he found that Harry and Malfoy had both vomited blood and were carried into the school infirmary.
