Harry Potter: The Dragon Lord Comes to Hogwarts

very good!

Very good Quidditch talent.

Professor McGonagall smiled in relief, and she planned to make the next decision in her heart.

Slytherin is so annoying!

He even secretly plotted the outstanding members of Gryffindor into the wizard sanatorium before the Quidditch match...

However, this decision is somewhat difficult.

According to Hogwarts regulations, first-year students are not allowed to participate in Quidditch competitions.

Professor McGonagall was lost in thought.

When she was hesitating.

On the grass not far away, a black-haired child dangled from the ground driving a magic broom.

"Harry Potter..."

Professor McGonagall was talking to himself.

She could see that Harry was acting awkwardly on the broomstick.

This level, at first glance, is the reaction of beginners only for the first time.

But in the next moment, the boy who was riding a magic broom wobbly before, unexpectedly...

Fly into the sky.

Harry gripped the magic broom tightly with both hands, and from his initial panic, he began to calm down.

"Very good! I can adapt to this feeling very well..."

This is Harry's most intuitive feeling about driving a magic broom, and what he has to do now is to save Ron who was hit by the spell "Petrification"!

Ron's body in front of him happened to dodge several magic rays one after another in the air, but the last ray still hit the magic broom under him.

The magic broom falls straight down along the wall in mid-air!

The wizard's robe behind Ron happened to be suspended in mid-air by a humanoid statue with a spear piercing through the clothes on the back.

It seems that there is always a risk of falling.

He had to "protect" his friend, this was Harry's only thought at this time.

In an instant, Harry's broomstick accelerated suddenly and rushed straight towards Ron who was hanging on the portrait.

Ron's wizard robe is constantly cracking with the downward gravitational force.

It was about to fall to the ground.

Harry had to accelerate again, and with all his concentration he rushed almost recklessly towards the statue.

Behind the statue is a wall!

Professor McGonagall frowned:

"This is so reckless....

So daring to ride a flying broom for the first time!

Once he couldn't stop and hit the wall, the injury would be serious. "

It seems that I need to make a move...

Thinking of what Professor McGonagall is about to do.

However, Harry's body was turning 360 degrees to the dangerous area, turning direction deftly.

At the same time, the palm stretched out and successfully grabbed Ron's wizard robe.

"call....."

Thank you so much.

Ron was still in shock, and he looked at Harry excitedly.

At this moment, Harry is almost like a hero.

Harry smiled slightly: "Don't worry Ron, we are...friends..."

Ron returned a silly smile: "Well...Harry...thank...thank you..."

But in the next moment, the wizard's robe could no longer bear the gravity and broke directly.

Ron's voice fell down before he finished speaking.

Hermione exclaimed, but still reached out and patted her chest:

"It's okay...it's okay, I forgot, Professor Rolanda just cast the spell [Mud Swamp] under Ron just now...it seems that he is safe..."

Dudley shook his head indifferently:

"No! No..."

Hermione was stunned: "How come? Didn't you...see..."

Dudley waved his hand and said calmly:

"I saw!

But according to the algorithm, the distance and the tension of the liquid can be inferred.

Ron fell from this height and was lying flat. This kind of contact area would bruise his skin even if it was the surface of the water.

If it's a swamp....

I think Ron's best outcome is a minor fracture...."

Hermione sneered:

"Probably not, Ron will be safe and sound..."

However, before Hermione's words fell, Ron's body fell heavily into the mud swamp.

Professor Rolanda looked back at the little wizards behind him and said with a serious face:

"Our lesson today is the use of the magic broom, not Quidditch training.

As you all have seen, Ron of Gryffindor disrupted the class, and I will report this to the Hogwarts Ethos Department...”

But before Professor Rolanda could finish speaking.

"boom!!"

There was a sound.

It was followed by a slightly painful exclamation.

The young wizards present, including Professor Rolanda, all looked stunned.

Because it turned out to be a scream...

"Oops! My God!"

Professor Rolanda turned around quickly, flicked his wizard robe and rushed to the mud pool under the tower on the other side of the lawn.

The young wizards of Gryffindor and the Slytherin branch surrounded them.

They also looked at Ron in the mud swamp in shock.

In Dudley's field of vision, Ron was lying flat on the wriggling swamp...

Hermione on the side was full of disbelief:

"Du... Dudley, how did you guess that?

No, how did you know Ron was going to "get hurt"?

Could this have something to do with the "tension" of the water you mentioned earlier? "

Dudley didn't answer Hermione's question, of course he wouldn't explain it to a girl, scientific logic.

Just like, the mud swamp is also a flowing liquid, and the external force that can reduce the surface area of ​​the liquid is called the surface tension of the liquid.

Destroying the surface tension is directly related to the contact area, which is the same as nails and wood.

Dudley looked at Hermione calmly and said indifferently:

"I think your attention is in the wrong place!"

Hermione tilted her head a little puzzled?

Dudley calmly stretched out his finger and pointed to Ron in front of him:

"Ron is hurt and as his 'friend' you should go up and 'help' him."

Hermione nodded subconsciously when she heard that!Although I didn't know what was wrong, I always felt that what Dudley said made sense.

"Okay, I'll go and have a look and help notify the Hogwarts infirmary."

Hermione ran forward twice and stood still!

Turning around suddenly, he said expectantly:

"After class is over, can you tell me about the principle of 'tension' in detail...

I....I'm really interested.

Also...I need to explain that "Ron" is not my friend, he...he is just my classmate! "
