Chapter 616 Street Lights
“Why did it become like this?”

Andrew looked at the Hogwarts campus, which theoretically should be extremely familiar to him, and couldn't help but sigh.

But Hagrid in the distance spoke up in a loud voice without any suppression, "Over here, Andrew, come and see my show!"

It was indeed a performance by Hagrid. The metal pole originally used to hang street lamps looked like a thicker billiard cue, or a longer baseball bat in Hagrid's hand, and was being danced with vigorously by Hagrid.

Harry and Sirius on the side were clapping and praising Hagrid for his style as a batsman.

"You're just looking for fun, aren't you?"

Andrew glanced at Sirius and found that Black, who barely looked like a professor last semester, now had a full-blown husky personality. He said he was here to inspect the construction of street lights in Hogwarts, but in fact he just came to have fun.

"What sin have I committed? I only kidnapped Dumbledore for less than two weeks, and now I have to join the campus construction work. Professor McGonagall didn't leave much work for Dumbledore, so she stuffed it all on me..."

Before he came back, he was still thinking about aerospace and the future, but after coming back he went straight into civil engineering - this rather realistic turn really made him want to laugh.

But it is a project after all, and an important one.

Hogwarts has already undergone two large-scale lighting installations - this time the scope was larger, including the public light sources in the lounge, the street lights by the Black Lake and leading to the greenhouse, the lights added to the library, and the lamps in each corridor, all of which had to be installed at once.

No one knew how Professor McGonagall threatened Peeves, but the elf rarely came out to cause trouble. As for the deans of the other three colleges, they were called back to watch over the installation of lighting fixtures in their own colleges, not to mention Dumbledore.

Anyway, no one escaped this time. Even Mr. Filch had to learn how to install and maintain lamps throughout the process to facilitate repairs after mischief-makers played pranks. Andrew even heard the professors who stayed on campus making a bet, but everyone bet that Gryffindor's lamp would break first, and the bet failed in the end.

"A big Bludger, Andrew!"

Hagrid shouted, interrupting Andrew's sigh.

"I don't know the structure of a Bludger, let's make a baseball!"

Andrew waved his wand, causing the air to condense, and with a casual wave, a basketball-sized ball flew at high speed directly towards Hagrid's head.

"cool!"

Hagrid's mouth widened, and he swung the lamppost violently and hit it straight.

"boom!"

With a loud collision sound, the ball that Andrew conjured flew directly towards the distant Black Lake and smashed directly into the Black Lake, causing a splash of water more than three meters high.

Harry and Sirius clapped their hands vigorously, while Hagrid weighed the lamp-pole in his hand and praised the quality of the Ministry's preparations.

"The material this time is really good. It feels much better than the trees in the Forbidden Forest!"

He waved the sturdy-looking street lamp with a beaming look on his face, "That's good, it's fully rolled out. Finally I don't have to carry an oil lamp out late at night." Due to some unspeakable punishment reasons, Hagrid's wand has not been released yet. He cannot use his wand for lighting in public and can only patrol at night with an oil lamp.

After this installation, Hogwarts is almost fully covered with lamps - although they are not powered by electricity and still rely on alchemical oil to work, due to recent technological updates, they can now be turned on and off with magical timers, which is convenient enough.

'It's a bit of a disconnect, researching aerospace while working on electric lighting... But it doesn't matter, there are areas without electricity in the aviation age... I think it would be best to come up with a solar alchemy storage device, but that requires laying out the materials.'

"Just be happy when you're out having fun, Andrew. It's the weekend, what are you thinking about over there?"

Ha… Sirius suddenly patted Andrew on the shoulder and said, "Don't think about those unhappy things all day long. The wizarding world has developed very well. You should go out and take a look. The school is too cautious. Diagon Alley has become completely unrecognizable!"

"What changes can there be?"

Andrew was stunned for a moment, then gave up the idea that he couldn't actually implement. He turned to look at Sirius and said, "The Leaky Cauldron can't be demolished, and the other shops won't have any competitors. At most, they can renovate the storefront and sell some new things. What can they expect?"

"You're wrong," Sirius shook his head. "It's changed a lot, especially the Leaky Cauldron. You won't believe it, but old Tom has spent money to renovate his own pub. Now the place has three floors!"

"Third floor?"

Andrew was stunned. "The Leaky Cauldron is on the third floor. Is it still the Leaky Cauldron?"

What has technology brought to the magical world, besides material things!

Wizards shouldn't make progress. They should live in crooked houses without even a lamp, and have to rely on candles and wands for lighting. Only then can people know that they are wizards!
He suddenly turned to a very skillful question and immediately threw the damn idea out of his mind.

'Damn it, I shouldn't have read Magic Reader and Forest of Thought just to write a legend.'

He began to regret it - although it was wrong for him to take the opportunity to slack off when Dumbledore came back, it was also wrong for him to read those things in order to hurt Dumbledore. Dealing with emotions turned into hurting each other!
"Yes, the third floor. The second floor is full of women and children. I heard that it was his granddaughter's idea, the one from Hufflepuff, Hannah. She's good at Muggle Studies. The second floor provides drinks and desserts, as well as some alchemy machines for children... that can catch puppets and the like."

Sirius spoke quickly, looking like he had been there a lot, "There are also some matching desserts, a cauldron that can automatically make popcorn... and the indispensable dream playback."

"That's a bit too comprehensive. There's no doubt that the first floor is a huge Quidditch live broadcast?"

"Exactly, Andrew!"

Sirius grinned widely, "It only now feels like a large street. Compared to Hogsmeade, it almost looks like a village. To be honest, there is basically no development here."

"It costs money to renovate. No matter how we renovate here, most of the people here are students, and the inspection is strict. Those who are not inspected will not even pass the hygiene test... Who will renovate it? The whole wizarding world will go there, and wizards now have money on hand..."

He had heard some inside information in this regard, but he was not clear about the details - he was not an expert in finance, and although no one would keep it secret from him, no one would actively communicate with him. It was nothing more than issuing more Galleons and releasing more supplies to force the wizards to have money while ensuring that the price of basic materials remained unchanged.

"You can't learn it from anywhere else. Just try Transfiguration and Herbology. Creating something out of thin air and absorbing it from the Muggle world is really cheating..."
