Chapter 224 The Real Treasure

"Really? Treasures make people wake up early..."

The next morning, when Andrew finished his routine run, he couldn't help but sigh when he saw the crowd that shouldn't have been there crowded around the Black Lake.

There are only about a dozen people running on weekdays, and the distances everyone runs are basically different - today everyone got up very early.

If the surface of Black Lake hadn't been frozen, Andrew suspected that someone would have jumped in right now.

But if the situation develops, jumping into the lake is not impossible - anyway, the squids by the Black Lake will not drown people...

"Never mind, I'm not a prefect, and even if it's true, it doesn't violate the school rules - we can't tear down the school, can we?"

Andrew shook his head, and even took a detour to the castle in order not to disturb the excitement of the group of people.

He had a lot of things to do today - go to the laboratory to review the Transfiguration skills he had learned previously, handle work in the office, and go to the library to complete homework and preview. He had no time to care about a fictitious treasure.

Transfiguration was unveiled to him for the first time, and he was very busy!

-

"This is not okay? Isn't it too harsh? How could you do that just now?"

Andrew sat in the laboratory, looking at the information beside him and the guesses he had written down, and he fell into a state of rage...

"Logically, this structure is a stable structure and meets some of the definitions of the rules, but I can't feel the rules manifesting themselves here anyway..."

He sighed, marked the project that had just failed, prepared to go back and ask Professor McGonagall, then turned his attention to the next item.

But at this moment, he habitually glanced at the laboratory's reminder device - it was silent, but it would leave a message about the visitor's purpose, but Andrew didn't know what the spell was.

The originally blank reminder device suddenly had one more sentence.

"We succeeded, it's in the lab next door, come quickly!"

???

The lab next door?
Andrew was stunned for a moment, and began to recall. He had some impression of the laboratory next door, but not much, because they only knew what was going on over there, and the main people in charge were Professor McGonagall and the dean to whom the laboratory belonged.

"Forget it if you can't remember... Let's go check and see if there's anything good..."

After all, the word "success" is not used casually. Except for the laboratory used by Andrew for practice, the other laboratories basically use Siko as fuel every day. If it is a key project, the fuel is directly replaced with Galleons.

He checked to make sure nothing was missed, then patiently checked again, then he felt relieved, locked the door, and walked directly to the laboratory over there.

"Wait…"

The more he walked, the more he felt something was wrong - this laboratory seemed to have been put into use not long ago, and it was arranged by him, just before the Christmas holiday!

It’s only been a few days and the results are already there?
Are you sure you're not here to defraud the Ministry of Magic of funds?

And the research goal is also old-fashioned - yes, the old-fashioned problem of electrification in Hogwarts!

Are you kidding me? This money-burning project is approved every year. You say it is successful. Who are you kidding? There is no money to be made even if you cheat. There is no funding to be allocated even if you cheat!

But it’s not good to be subjectively skeptical—at least take a look.

So even though Andrew suddenly lost interest, he still didn't give up and walked straight to the laboratory - it was approved not long before the holiday, and he wanted to see what was going on.

With suspicion, Andrew knocked on the door of the laboratory - to be more precise, he activated the message system.

But before he could say anything, the door suddenly opened, and in front of him came a Hufflepuff student with a red face full of excitement.

"You're here, Taylor, yes, yes, we succeeded just as you said!" What did you say!

I'm doing a good job in the office and I have no intention of defrauding funds with you. No matter how bad the Astronomy Tower is, it is still a hundred times better than Azkaban!
But he was soon pulled in - two Gryffindors, three Ravenclaws, and five Hufflepuffs. These were all the members of the laboratory. At the moment, they all had red faces and looked like they had the urge to take off their clothes and run around the Black Lake a few times.

"This way, Taylor, this way!"

Andrew was almost forcibly pulled over - in the center of the crowd, a crude benzene device that Andrew didn't know how to describe was placed on the table. It was completely different from Andrew's imagination of mechanical or alchemical devices, and was as crude as discarded parts in a garbage dump.

However, he soon retracted his evaluation and felt deeply guilty for his misjudgment.

Because as the Gryffindor boy standing next to the machine reached into the thick bars and touched a spot with his wand, a light of the old-fashioned incandescent lamp that he was all too familiar with appeared on a thin wire...

'ah? ’

His eyes widened and his mouth couldn't close.

isn't it?
joke!

Merlin's beard!
What's happening here!
Isn't it that the various protections within Hogwarts castle add up to form an invisible magic field, which then creates the problem of electromagnetic shielding?

"How did you do it?"

He asked sincerely.

"That's what you said."

"I?"

Andrew pointed at himself, looking confused - could it be that my future self came here using a time turner?

What a joke, even a good time-turner doesn't have the ability to travel through time for so long. This is Hogwarts, not a legend of Dumbledore.

"Yeah, you did, Taylor."

The other party nodded. "If you talk about electricity, it's so vague and far-fetched. Why don't you start with lamps? After all, the incandescent lamps most commonly used by Muggles are made by heating tungsten filaments. It has something to do with electricity, but it's not that difficult."

...

It seems to have been said.

Andrew remembered that when he got the report to the professor, the professor felt that the experiment still had to be carried out, so he asked him to take people to Mr. Filch to move the failed data.

After all, the old students had repeated this experiment many times, and a lot of failed data had accumulated. He saw that those students were a little frustrated at the time, so he casually mentioned a few things he knew about electricity, and then paid no attention to them.

After all, this is an experiment that has failed more than a dozen times in a row...

"So what have you been doing during this time?"

"Yes, we used alchemical instruments to create high temperatures to heat the tungsten filament, and then successfully made a lamp!"

???

Yes, the working principle of incandescent lamp is to use electricity to pass through tungsten filament, and then use the current to pass through the tungsten filament to cause the resistance of the tungsten filament to become higher and higher, thereby generating a lot of heat, heating the tungsten filament to about 2,000 degrees, so that it enters the incandescent state and lights up...

The so-called light bulb is actually a vacuum glass cover to ensure that the filament slows down oxidation and seals the electricity...

In other words, under his guidance, his dear seniors did not invent electricity, but they were so strong that bricks flew flying, and they directly invented lights...
