Draco Malfoy comes from the pure-blood Malfoy family. His father is the contemporary head of the family and has great influence in the wizarding world.
In the Harry Potter series, his frequency of appearance is second only to the three protagonists.
In the words of Aunt Rowling, this is a boy who looks handsome, is eager to express himself, and has a good heart.
"Any more questions, Draco?" Wang Xu stood on the podium and looked into Draco's eyes.
Draco shook his head slightly, sat down without saying a word, crossed his arms and looked at the blackboard.
Wang Xu withdrew his gaze, held a teaching stick in his hand, pointed at the first item on the shelf, and said: "Type 72 anti-infantry mine, 8.8 cm long, plastic shell, anti-metal detection paint, explosion range 14 meters, contains
650 steel balls can be fired out in a fan shape at the moment of explosion.
In the Muggle world, landmines are an important part of defenses. They can effectively prevent infantry invasion. Suppose that a Death Eater invades your house. If he steps on this anti-infantry weapon without knowing it,
Landmine, this landmine will send him to the sky. More importantly, in the wizarding world, there is no magic to detect landmines, which is invulnerable to a certain extent."
"Professor, what if the other party was riding a flying broomstick when they invaded?" A student stood up and asked Wang Xu.
Wang Xu moved the teaching stick in his hand to the side, pointed at the rocket launcher on the second shelf, and said calmly: "RPG-18, codenamed Fly, Soviet product, reliable performance, durable. Comes with long-range sight, effective range
800 meters, the moment you pull the trigger, the rocket will fly to the target at a speed of 338 meters per second. Currently, the fastest flying broom on the market is the Firebolt 2, with a speed of 150 miles per hour, which is 150 miles per hour.
67 meters per second.
The speed of rockets is five times that of Firebolts. Within three hundred meters, when you aim at him and pull the trigger, it only takes one second to hit him. If the distance is closer, it will be easier.
It only takes 0.3 seconds from launch to hitting the target within 100 meters, and there is no chance to react in such a short time."
Having said this, Wang Xu took down the rocket launcher and said with a smile: "I'm just talking about data. Many people who come from wizard families and have no contact with Muggle society may not understand its power. Now I can perform it for everyone.
."
Wang Xu walked to the window with a rocket launcher and motioned for the students to come and take a look.
Hundreds of little wizards surrounded him one by one, stretching their necks to look outside.
"Our classroom is on the second floor. Look far away. Downstairs is the playground for flying lessons, and six hundred meters away is the Quidditch training ground. I will now choose the target of my attack on the tower of the Quidditch training ground.
, please pay attention."
Wang Xu raised the rocket launcher, locked the tower through the sight, and suddenly pulled the trigger.
Whoosh!!
boom!!!
At a distance of 600 meters, the rocket only takes 1.5 seconds. If you pull the trigger here, it will hit the target there.
As soon as they caught sight, the tower that was hit exploded, and a fireball formed by the explosion rose into the sky.
Wang Xu put down the rocket launcher with a smile on his face.
The little wizards around him all had big mouths. Even Professor McGonagall, who came to see him in class, subconsciously took a breath of air.
"Can a powerful blasting spell have such power?" A pure-blood wizard who had never seen a rocket launcher couldn't help but ask his companions.
His companion shook his head slightly. The powerful blasting spell could blow up a wall, but it could not blow up the entire tower.
Moreover, the powerful blasting spell is a relatively advanced magic that can only be accessed by sixth- and seventh-grade students. It would be good if only one of ten wizards can cast it upon graduation.
"The emergence of rocket launchers is to attack local light armored vehicles and low-altitude flying helicopters. Take the model in my hand as an example, it can penetrate 375mm of armor frontally, which means hiding in a house
It is absolutely impossible to hit a rocket. Once the rocket explodes in the room, the shock wave will kill you alive."
Wang Xu turned back to the podium, placed the rocket launcher on the wooden stand, and picked up the AK47 assault rifle.
"This is an AK47 assault rifle. It has an effective range of three hundred meters. The conventional magazine is equipped with thirty rounds of bullets. A drum of 75, 100 or 120 rounds of bullets can be used to increase the firepower. The rate of fire is as fast as raindrops."
Wang Xu picked up the AK47 rifle, looked at Professor McGonagall, and asked: "Professor McGonagall, can you cast an armor protection spell on the blackboard?"
Professor McGonagall looked around and found that the little wizards were all looking at her with expectation in their eyes.
"Okay!" Pulling out the wand, Professor McGonagall pointed forward and whispered: "Armor for protection!"
Whoosh!
The tip of the wand emitted white light, which circled around the blackboard on the podium, forming a translucent shield.
Wang Xu waved his hand to signal the students around him to step back. When everyone was five meters away, he opened fire with his AK47.
da da da da
The bullets shot out like raindrops, and the empty shells flew out of the ejection holes and landed on the ground with a crisp crashing sound.
When the first bullet hit the blackboard, the Armor Protection Charm glowed white and quickly blocked the bullet, then the second, third, and fourth rounds followed.
When the fifth bullet hit the blackboard, the armor protection charm was directly penetrated, and the blackboard was shattered into pieces.
"Wow!" An exclamation came from the ears, and many little wizards looked in disbelief.
Wang Xu knew that the protective spell was shattered by five bullets, but in the eyes of the little wizard, the shield was shattered between tongues of lightning and flames.
This is also true. With the firepower of the AK47, a 30-round magazine can be emptied in one second.
It also means that in a sudden attack, a wizard who has cast a protective spell for himself will have his shield shattered in an instant and will be smashed into pieces by a hail of bullets in less than a second in front of an AK47.
"The strength of the armor protection spell depends on the magic level of the caster. As the vice-principal, Professor McGonagall's strength is unquestionable in the wizarding world, so her armor protection spell is more powerful than ordinary people."
Wang Xu held up the AK47 with one hand, his eyes fell on Harry in the crowd, and said with a smile: "Harry, cast a protective spell on the table on the podium."
"Armor protection!" Harry took out his wand and added a shield to the table.
Wang Xu pointed at the table, and under the gaze of many young wizards, he started shooting at the table.
With the first bullet, the protective spell provided perfect defense, but with the second bullet, the protective spell began to fade.
With the third bullet, the shield disappeared and the table was penetrated.
Wang Xu lowered the muzzle of his gun, showed everyone the bullet holes on the table, and said, "Harry's protective spell can withstand two bullets, and will only be pierced by the third one. This shows that Harry's protective spell,
It's a little worse than Professor McGonagall. The difference lies in the fact that one needs five bullets to penetrate the shield, while the other only needs three."
At this point, Wang Xu paused slightly and then asked: "Is there anyone else who wants to try?"
"Me!" A wizard from a Muggle family took the initiative to stand up.
Wang Xu first asked him to cast a protective spell, and then used ak to shoot.
In just one move, the shield was broken through and hit the chair that had the protective spell cast on it.
Wang Xu picked up the chair and looked at it. The bullet marks on it were very light and did not even penetrate the wooden board. Apparently, the projectile had exhausted its impact when breaking through the protective spell.
"Everyone can circulate it and take a look. This is a fourth-grade classmate. His magic level is equivalent to most of you. This is the result of his protective spell facing a hot weapon." Wang Xu handed the chair to this person.
A classmate asked him to take it and show it to everyone.
Hundreds of students gathered around to watch, and some were puzzled and asked: "Is there such a big gap between Koracha and Harry? Harry's protective spell blocked two bullets.
It took three shots to pierce through. The protective spell of Kailacha was not blocked at all, which is incredible."
The students around were talking a lot and couldn't figure out why.
Wang Xu clapped his hands to signal everyone to be quiet and explained: "Harry's magic level is close to that of an adult wizard. His strength is no less than that of an ordinary wizard and cannot be treated at the level of a sixth grader."
The experiment continued, and students from the fourth, fifth, sixth, and seventh grades all came on stage to test the strength of the protective spell.
Basically, the protective spells of fourth- and fifth-year students can be defeated with one bullet. The only difference lies in whether the tables and chairs are penetrated or not after the protective spells are defeated.
Students in the sixth and seventh grades are better. Their protective spells can basically withstand the next bullet, and will only break when the second bullet hits.
A few elites can do the same as Harry, blocking two bullets, and only the third one penetrates the shield.
There was nothing further up, and Professor McGonagall even stopped Astronomy Professor Aurora Sinistra who was passing by in the corridor for the sake of experiment.
As a professor, Aurora's protective spell only blocked three bullets, which was better than Harry who blocked two bullets, but not as good as Professor McGonagall who blocked four bullets.
"Now is the question time, everyone can raise their hands to ask questions."
Wang Xu stood on the podium and looked down. Many young wizards raised their hands. Among them, Hermione's hand was raised the highest, so he smiled and said: "Hermione, what's your problem?"
