hello mr draco

4 Privet Drive is covered in sunlight.

Harry had just released Hedwig to look for food, and all his actions were to quietly avoid Uncle Vernon.Because Uncle Vernon hates owls shitting all over the place.He does all the owl droppings in the garden by himself.

For Harry, not being yelled at by Uncle Vernon was already a very good treatment.He had just finished disposing of the bird droppings in the garden when Cousin Dudley ran out of the house with a greasy chicken leg in his hand.

After seeing Harry, Dudley quickly stuffed the chicken leg into Harry's mouth while his parents didn't see.

"You need to fatten you up this holiday!"

Harry took the chicken leg in his mouth and ate it without hesitation, because he was still holding the sweeping tool in his hands, so he couldn't take the chicken leg Dudley was holding in his hand.Enjoying the other party throwing food at him, gnawing and gnawing, and accidentally licking Dudley's fingers with his tongue, his whole body was horrified.

That feeling is like being electrocuted to the whole body by a small electric current. After the horror, there is a creepy comfort.

Dudley was complaining about the damn weather, so he didn't notice the hiccup.He was also thinking about what kind of opportunities he would create for Draco and Chen Junyu to play. There seemed to be quite a lot of places to play in London.And there are also playgrounds in this era.

After dealing with the bird droppings in the garden, Harry happily walked into the shady and shiny kitchen.Pick up two loaves of bread and a piece of cheese that are on the kitchen table.

Dudley had just gone upstairs, and he took Dudley's snacks with him.Luckily Aunt Petunia and Uncle Vernon didn't know that Cousin Dudley had been stuffing his rations into his stomach all this holiday season.He pinched the fat circle on his face, and he almost forgot the feeling of being hungry before.

Arriving at Cousin Dudley's bedroom, Harry put the cheese and barbecue on the table, leaned over to the desk, and watched Cousin Dudley open the letter.

"Who sent it?"

Dudley was startled by Harry's sudden voice, and the letter in his hand fell to the ground.He picked it up quickly, and felt guilty, "Draco's..."

Dudley didn't want Harry to see the content of his chat with Draco at all, he didn't want to spoil a good protagonist.How many Harry Potter fans would have to whip him to death.

Thinking about it, Dudley felt terrified, shrank his neck, and hurriedly stuffed the letter into the drawer.

"He has already written four letters over this holiday—what are you talking about?" Harry had a faint feeling of being cheated. His cousin, who had always been unreserved in front of him, started to have his own little private space. Yes, he felt inexplicably uncomfortable.

"It's nothing, it's just about potions." Dudley said, pointing to the grilled meat and cheese on the table, "Please help me with these, I managed to lose the fat, Cake or something, I don't want to eat it for the rest of my life!"

After speaking, Dudley watched as Harry went to get the cheese on the table.He didn't dare to take out the letter to read it anymore, he planned to read it at night when he went to sleep.After all, Harry was by his side, and he always felt as if he had done something wrong.

Rubbing the dog-gnawed hair cut by his mother, Dudley looked at the calendar hanging on the wall and exclaimed, "Guess what day tomorrow is, Harry?"

Harry looked up suspiciously, still holding a piece of cheese in his hand.There was a little bit of cheese on the corner of his mouth, and after he licked it with his tongue, he said puzzledly, "What day is it?"

"Of course it's your birthday!" Dudley smiled with his lips curled up, and the Muggle pen he held in his hand was turning rhythmically on his nimble fingers.

……

Home of the Redhead Weasley.

Obviously, the Burrow doesn't fit the bill for wizards, but to Muggles it's full of wonder, full of magical creatures and magical items.The crooked wooden house was at least four stories high, and it must have been built crookedly by magic.

The Burrow was situated just outside the village of Ottery San Catchpole, but it was so well hidden that not even the postman knew where it was.There are ghouls in the attic of the Burrow, and goblins in the garden.

The house has several floors, and the space is cramped but comfortable.There is a flock of chickens outside the house, there are many goblins in the garden, and like other wizarding homes, there are all kinds of magical equipment and clothes here.

Chen Junyu was sitting on a chair outside the house, the morning sun was like stars on a prairie fire, and he was drinking a cup of tea that Arthur had just brought for him.He received a letter from the owl yesterday and was invited to come and play.

The Weasley children heard that they ran to Muggle World to pick up Harry that night, so they should be on their way now.Chen Junyu took another sip of tea, and a goblin jumped over his leather shoes, which looked particularly funny.There was also a goblin trying to climb up the wooden table leg, but unfortunately its ability was limited, and it fell down after climbing halfway.

Arthur's wife just yelled loudly, and after a while, Chen Junyu heard the sound of ping-pong-pong from the third floor of the attic.It must have been the sound of some child coming down the stairs.But the feet are a bit strong, and it is a miracle that the house was not destroyed by them.

Arthur dragged out a thing from the warehouse, walked around the direction of the kitchen mysteriously, for fear of being seen by his wife, hid the thing under the cloak, and sat down at Chen Junyu's table with an excited face.

A small electric fan without blades was regarded as a treasure by Arthur and placed on the table.He looked a little embarrassed, but Arthur knew that when talking about Muggle items, no wizard had enough experience with Professor Chen in front of him.

"I've never been able to figure out what this is? Got it from a junkie. It had three leaves on it, but I took the leaves off because it was too big."

"Arthur, maybe it would be more perfect if you didn't remove his fan blades." Chen Junyu looked at the electric fan, and could only describe his fiasco as horrible.After the blades of the electric fan were removed, he really couldn't think of any use for this thing.

But in the physics class, the physics teacher taught them how to change the electric fan into a motor.

"What are you going to do with this?"

Arthur looked frustrated when he heard Chen Junyu's answer.At first, he thought he had bumped into something terrible, even looking at the electric fan with its blades removed, his eyes were very pitiful.

"Isn't he useful at all? I mean, no matter what you transform it into, as long as it's useful?" Arthur still had a little hope in his heart. The remaining insufficient money was exchanged for Muggle coins. He bought such a useless thing. He was afraid that his wife would find out, and he would probably die miserably.

Chen Junyu worked his hands up and down, and moved the electric fan in front of him to check it out.This is a very typical, very old electric fan, and it is not impossible to completely convert it into a generator, but it is mainly missing a lot of things.

He tapped lightly on the case of the electric fan with his fingers, and all the assembly seemed to be automatic and conscious, and they spread out one by one very regularly, showing the internal structure.

Chen Junyu pointed to another thing and said: "Household electric fans don't have the basic requirements of generators, but the basic requirements of generators are."

Arthur listened carefully, and took out the handwriting in the wallet. The quill on it automatically jumped into the ink tank, and then automatically rewritten everything Chen Junyu just described.

"The coil cuts the magnetic force line in the magnetic field. There are several elements here: the coil, the magnetic field, and the cutting magnetic force line. The household electric fan lacks the important condition of the magnetic field. The coil of the household electric fan is not suitable for the coil of the generator. The generator The winding method, direction, position, and connection of the electric fan are different from those of the electric fan. The structure of the household electric fan is not suitable for hand-cranking. The hand-cranking generator must have a "handle" to obtain a higher speed."

As soon as he heard that there was no such thing, Arthur asked impatiently: "Is there any way?"

Chen Junyu frowned and thought about it carefully. Fortunately, they had done this experiment. Although the small generators they used were toys, they still had all the necessary tools.

"Look for an old-fashioned hand-cranked telephone, remove the internal generator part, add the ready-made crank handle, and then observe and experiment first. When the crank handle is shaken quickly, the output AC voltage can reach 110 volts to 170 volts." After Chen Junyu finished speaking, he quickly added: "Not every experiment can be successful. What I said are just methods."

Arthur was stupefied.Don't expect a wizard who doesn't even understand physical chemistry to understand the products of human physics.Chen Junyu also knew that although he told Arthur a lot of basic knowledge about Muggles, making the generator was really troublesome.

Seeing that the guy in front of him always looked worried, Chen Junyu encouraged and comforted him: "Isn't your car remodeled very well? I believe you can do it. If you add magic to the engine, I don't know if it will increase current output?"

The two of them were discussing in the yard, and Arthur realized that he had been outside for too long, so he quickly hugged the electric fan without blades in his arms, and quietly moved it back to the storage room.

As soon as he walked on his front foot, there was a booming sound in the sky on his back foot.That kind of sound is like a jet, from far to near, and it is intermittent.
