Hogwarts, Muggle Studies class.

The classroom was quiet and dim, with the only source of light coming from the white curtain in front of the blackboard, which glowed faintly.

The shaman sits cross-legged in a dark corner next to the curtain, and the projector is projecting images of the movie Interstellar onto a white curtain hanging in front of the blackboard.

Interstellar is about the not-too-distant future, with the deterioration of the earth's natural environment, humanity is facing the threat of not being able to survive. At this time, scientists discovered a wormhole near Saturn in the solar system, through which it can break the limits of human capabilities and go to outer space to find opportunities to continue life. An expedition team travels beyond the solar system through this wormhole, and their goal is to find a planet suitable for human settlements.

For the filming of the film, director Christopher Nolan specially invited the famous astrophysicist Kip Thorne to collaborate across borders, just to create the most scientific wormhole.

Kip Thorne, Feynman Professor of Theoretical Physics at the California Institute of Technology, is one of the most prominent scientists in the field of black holes and general relativity, and he is a longtime friend of Stephen Hawking and Carl Sagan. As an example of his status, in the film "The Theory of Everything", among the three supervisors who judged whether Hawking's doctoral dissertation passed or not, one was the famous Penrose, the other was Hawking's teacher Sharma, and the other was Kip Thorne.

In early 2013, Thorne gave Nolan a few months of lessons, explaining how black holes bend light and space-time. Therefore, the whole film is based on Thorne's theoretical knowledge. Afterwards, Nolan revealed that the most rare thing about Thorne was that he never immediately answered the questions he asked, but went back to check the papers, discussed them with the scientists, and then did a series of calculations before finally telling himself the results. Even so, Thorne didn't feel upset.

Paul Franklin, the special effects supervisor, also discussed with Thorne in order to create a realistic space scene that was in line with physics.

He had Thorne write down many formulas, and Thorne even gave Franklin his notebook, full of the results he had documented over the years.

Franklin taught the VFX team these formulas, and they were asked to write new VFX software and algorithms according to Thorne's formula, and finally got the image that best conformed to the laws of physics.

This film was chosen by the shaman specifically to arouse the wizard's interest in space engineering. The film depicts black holes, depicting relativistic effects, artificial intelligence, suction cups, solar systems and other scientific concepts, which are very suitable for scientific enlightenment.

And this film is from the Overworld in 2014, it is a relatively new movie, although there are criticisms in the story, but the reputation in terms of special effects is not bad, this is what she needs.

It's time to open the eyes of these wizard dirt buns.

You must know that the wizarding world at this time has always revealed discrimination against ordinary people, intentionally or unintentionally, and even Headmaster Dumbledley once said in a letter when he was young: "Yes, we are given the power, and there is no doubt that this power can enable us to make rules, but it also requires us to have a sense of responsibility for the rules." ”

Although Dumbledore was not as radical as Voldemort and wanted to kill all Muggle mortals, the idea of naked beings looking down on inferior creatures was unmistakable.

Even Hermione's parents are mortal wizards, and when it comes to mortals, they are also muggles.

Muggles are a scorn for mortals!

The shaman knew that it was impossible to correct the stereotypes of these wizards, so he could only try to start with the young wizards. Of course, even if she fails, she doesn't lose a dime, she just thinks it's fun, as if some people go to the forum just to find someone to argue.

Soon, the film reaches the final scene, on a desolate planet, Emilia sits on a rock, looking expectantly into the distance, she is wearing a spacesuit, but not a helmet, indicating that this is a planet where humans can immigrate.

Emilia stood up and turned to walk down the rocks. The camera zooms up, revealing the dots of light beneath the rocks.

Humanity has already colonized this planet.

The movie ends.

With a wave of his wand, the classroom suddenly lit up, there were no candles, no electric lights, the light seemed to come from the walls, ceiling, and floor, and it seemed as if there was no source.

The pale-faced Draco Malfoy yawned, sat up, and said, "Is it finally over?" Muggle stuff is boring. “

"That's right!" Pansy Parkinson immediately chimed in.

Muggle-born Hermione Granger turned her head and glared at them fiercely. Most of the young wizards looked at Malfoy unkindly, with only the Slytherin students glaring back.

"The class is noisy, and Slytherin deducts a hundred points." The shaman said lightly.

Draco Malfoy stood up sharply, his face flushed slightly, and his wand clenched.

The Harry Potter trio also got nervous, and they all clenched their wands, ready to fight.

The atmosphere in the classroom grew stiffer, and the wizards all held their breath, some secretly expecting a fight, others hoping to escape from the classroom.

Suddenly, Pansy Parkinson stood up and chanted the incantation into the projector: "Four-five......"

Before she could finish her sentence, a red light knocked her wand flying.

Malfoy and his henchmen drew their wands one by one, ready to kill the projector.

Six red lights struck away the wands in their hands at the same time.

The classroom fell silent, and all the wizards stared at the shaman in amazement, as she had grown six arms, each holding a wand.

The shaman put away his wand and announced loudly, "Class." ”

As soon as she stepped out of the classroom, Professor Snape walked in, stood on the podium, and quietly looked under the podium, not looking at the wizards, but everyone felt that Snape was watching her, and the classroom fell silent. "The Ministry of Magic will send someone for a medical examination in a day's time. Blood had to be drawn, and those Muggle doctors told them it was best not to eat anything tomorrow morning, and to save their appetite for their last meal before leaving school at noon. “

++++++++++++++++++++++++++++++++++

The shaman left the classroom and went to the Ravenclaw common room, sprinkled some Floo powder into the fireplace, the flames whirred, and the shaman stepped inside.

The next second, she was emerging from one of the rows of fireplaces on the walls of the Ministry of Magic's hall.

She left the hall and made her way to the Wind Tunnel at the bottom floor of the Ministry of Magic.

When she opened the door, Zhou Zhou and Rachel were looking at the screen on the console. The shaman walked up behind them and looked at the screen through Rachel's shoulder.

I saw that in the wind tunnel, Laura moved easily in the strong wind, advanced 50 meters in five seconds, and cut off the target with a sword.

"It worked!" Rachel said excitedly.

"Or my internal force bubble idea works." Zhou Zhou said with a smile.

"Does that mean that telekinesis-type enemies won't be a threat to her in the future?" The shaman asked.

"It depends on how the user uses the telekinesis himself. If he's changing, it's going to take time for Laura to beat him. Laura said she had come out of the wind tunnel.

At this moment, the door opened behind them, and Sun Hongmei quietly walked in. When the remaining members of the Red Blood Cell team were looking at the wind tunnel video replay on the screen, Sun Hongmei pulled out her wand and suddenly said, "Avada asks for his life." “
