In the afternoon of the last day of classes at Hogwarts this semester, the third-year students arrived in the Muggle Studies classroom with great curiosity.

Muggle Studies classrooms have been converted into lecture halls, so you don't have to fear of being blocked by the heads of your classmates in front of your seats.

On one side of the windowless classroom, there is a row of shelves covered by curtains, and students cannot see what is on the shelves.

At the very front of the classroom is a large glass screen, and the professor's seat has been moved from the middle of the classroom to the left.

There are many students' names on the screen, and when students walk into the classroom, they will see their names change from gray to gold on the screen.

At the bottom of the screen, if you get closer, you will see a red "CHANGHONG" sign.

Zhang Xu sat at the back of the podium, looking at the magic version of the tablet controller in his hand like a tablet of the future, and the automatic roll call system was displayed synchronously on the large screen in front of the classroom.

This automatic roll call system was developed by Zhang Xu based on the technology of the live point map, which can automatically display and record the entry of different students into the classroom, as well as the time of entry.

Because there were no electronic products in Hogwarts Castle, Zhang Xu purchased a spell version of the playback system from China. Only then did he know that the spell version of the TV had almost reached the level of the TV twenty years later in terms of playback effect. The disadvantage is that you can't directly receive the wired and wireless signals of the TV, you have to use equipment to convert, and the conversion time is too long to broadcast live. However, it is still possible to play movies and PPT.

Since the students were looking forward to today's lesson, the staff was due five minutes before the start of the class.

After Zhang Xu's name on the last student on the class list lit up, a short video began to play.

The screen suddenly goes black, then gradually lights up, revealing the foyer of Hogwarts Castle. At the same time, muffled music sounded.

The students see the basilisk appear on the screen along the stairs of the foyer with Lockhart. At the same time, the music in the classroom became tense.

Suddenly, accompanied by the sound of high-pitched background music, Peeves with two packets of quicklime rushed into the sky, smudging the basilisk in the face.

When Peeves is glared at by the basilisk's intact other eye, the music in the background becomes tragic as Peeves turns into black smoke in slow motion.

Then there is a suicidal assault by five daredevils to majestic background music, which ends with two petrified students falling to the ground in slow motion with a top-down leader directly above.

Next, the scene of Zhang Xu rushing out and throwing a grenade to blow up the other eye of the blind basilisk flashed, and the scene soon changed to the students attacking the basilisk together, the professor coming to help after several dangers, opening the passage to cover the evacuation of the students from the cafeteria, and Scarlet blocking the basilisk on the stairs alone, and the background music became excited.

On screen, the basilisk is seen from an aerial perspective, from a first-person perspective of the students, and even with the basilisk pounced less than two feet in front of the camera with its large mouth.

At the end of the film, Dumbledore's phoenix sends Harry Potter the Sorting Hat and the Gryffindor sword, and then the audience follows Harry Potter from the perspective of Harry Potter as he grabs the phoenix's leg and flies to the head of the basilisk.

Eventually, the entire short film ends with a close-up of Harry Potter's face from far to near.

At the end of the video, the students in the classroom responded with warm applause. The students who appeared in the video began to brag about it.

After deciding to meet the basilisk in the foyer, Zhang Xu asked a group of ghosts to help place the video crystals in various places in the foyer.

After finishing work, Zhang Xu found that these video crystals were not burned by the eyes of the basilisk, and it is estimated that the eyes of the basilisk will only burn the things in the path of the gaze when there are creatures behind them. This kind of very magical but unscientific thing, Zhang Xu did not delve into it.

Later, Zhang Xu copied the video crystals and the video saved in the video brooch worn by himself and Harry, edited it and added the burning song as BGM to make this short film.

In his previous life, when Zhang Xu was in college, he edited various video clips and passed them to Lack B Music, and he has rich experience in this area.

Now it seems that the film is working well, and the audience in the classroom has reacted strongly.

Wait until the students have quieted down a bit, and it's time for class.

Zhang Xu replaced the content on the big screen with the words "Muggle Studies Class" and walked to the center of the podium.

Looking at the students who had quieted down, Zhang Xu said to the students, "Welcome to Muggle Studies. In this class, you can give your wand a break. ”

The students in their seats laughed.

Zhang Xu continued: "Although everyone's wand can rest, but the brain can't rest. ”

"When a human figure appears on the moon, is it a human or a ghost? What was hidden behind the birth of the steam engine? Why are wars in the world so frequent? Who is driving the development of science and technology? Behind all this, is it Muggle progress or the decline of tradition? Is it the explosion of science and technology or the helplessness of survival? Stay tuned to Muggle Studies as we follow the textbooks into Muggle life and uncover the secrets behind the Muggle world......"

"Next, I would like to announce some of the rules for adding and deducting points in our classrooms."

"Students who are late will be deducted one point for every minute they are late, and students who need to ask for leave, please hand over the leave slip signed by your dean to me before three o'clock on the same day, or entrust your dean to hand it over to me."

"You can go to class just like you would in a history of magic class, you can be in a daze, sleep, and do homework on other subjects. But there is one thing, you can't disturb other classmates who want to study in any way, such as snoring while sleeping. ”

The students burst into laughter.

"If anyone influences other students who want to learn, five points are deducted for each student affected."

"Also, no matter how well you do in class, I will treat any student's assignments and exams the same."

"Speaking of homework, I don't want you to copy other students' homework, and if I find someone whose homework is a lot similar, I will treat them well. Believe me, you don't have as much experience when it comes to plagiarism. ”

The students burst into laughter again.

"After talking about the sad deductions, let's talk about the pleasant points."

"When I ask a question, whoever of you raises his hand first will answer it."

"One point will be added to the basic score for the correct answer, and then depending on the completeness and depth of the answer, the extra points will be set at five points from one point to five points."

Then Zhang Xu waved his wand, and a hummingbird with a blue light flew out of the podium.

"This hummingbird will fly to the head of the student who raises the fastest hand on its own, so whoever it flies overhead, will answer the question."

"When a student asks a question, with my consent, which student can answer his question will also get extra points. But don't let anyone think of colluding to get extra points, this can't fool me and the hummingbird. ”

"That's it, is there anyone against it?"

The students in their seats shook their heads.

"So let's start our first learning." Zhang Xu said, "Today we will first learn about the history of the development of the Muggle world. ”

Zhang Xu walked to the podium, "Next, everyone, please look at the big screen." I will show a documentary about the history of the world. If you have any questions you have while watching, you can record them first, and you can ask them after the documentary is played. ”

The students began to watch the documentary on the big screen intently.

The one-hour documentary tells the story of the history of human society from the Stone Age to the collapse of the Soviet Union, and focuses on the development of science and technology after World War II and the war.

The students, who had never experienced this kind of class experience, watched intently on the big screen.

The one-hour documentary does not tell the history of human society in too much detail, and Zhang Xu only gives students a preliminary impression of the history of the Muggle world, so as not to think that the Muggle world is still stuck in the Middle Ages like some wizards do.

Zhang Xu was very surprised to find that most of the students who took this course were students from the Snake Academy.

After asking the students of the Snake Academy who he was familiar with, the students of the Snake Academy said that it was because they didn't understand that they needed to study, which made Zhang Xu relieved.

Therefore, Zhang Xu chose to crush their three views from the beginning by focusing on the Second World War, space technology, nuclear weapons and other scientific and technological achievements, so that they could re-understand the Muggle world at the end of the twentieth century.

As you can tell from the expressions on the students' faces, the method was a success.

The war machines of World War II, the atomic bomb explosion and the ruins after the explosion, and the Apollo program landing on the moon shocked the young wizards from the wizarding family.

The same event, the feeling of watching a documentary, is not comparable to reading a book in the reading room before.

After the documentary, the students asked questions, mainly about post-World War II technology.

From the use of electrical appliances to whether Zhang Xu can make an atomic bomb, there are all kinds of questions.

Even Malfoy, whose right arm was hanging in a bandage, raised his left hand and asked Zhang Xu with a look of eagerness how he could become an astronaut.

Fortunately, Zhang Xu has a wealth of knowledge and can answer all kinds of questions.

The end of class came in a variety of questions and answers. After arranging for the students to write a documentary, Zhang Xu announced the end of the class.
