This is what Ravenclaw looks like..

Chapter 262
"Wires are a definite no-no..."

“That’s the problem – we skimped on the lighting, and then we can’t skimp on the rest…”

More magical protection, less Muggle technology.

While Andrew was sneaking around hiding himself, a group of prospective graduates in the laboratory were almost losing their hair.

Hogwarts's cumulative protective system rendered electric current, the foundation of Muggle technology, ineffective - perhaps electricity was considered some kind of magic and thus lost its effectiveness.

This is where the problem lies - among Muggle technology, incandescent lamps are the lowest level. Because they have undergone two conversions, they can still be implemented after jumping over and directly changing the electric current heating into magic. The following ones are basically impossible to copy.

At least not at Hogwarts - but the problem they were facing now was to develop a lamp more suitable for a greenhouse.

"This is almost impossible... We can't even do Transfiguration. What we are involved in, no, there is no Transfiguration course for filaments in the entire Hogwarts, right?"

"What else do we need to do now?"

"A lamp that is more suitable for growing plants... The tungsten filament cannot be changed, and we can't tamper with the glass... And that doesn't matter..."

"Or gas? The stuff that fills the lamp?"

"It seems like there is a way... and I saw some information some time ago that Muggles also used this method..."

Although it feels a bit... well, like plagiarism, there is nothing wrong with continuing to explore the path of our predecessors.

“It’s really scary…”

In the office, Percy was still sighing - in theory, Hogwarts was a pure school that would not allow unrelated people to enter for a long time.

But after the visits of those herbal masters, the definition of irrelevant people seemed to be completely revised.

The school board said nothing. As for Professor McGonagall, she didn't even seem to mind the trouble. Not only did she have to run to the greenhouse for a long time, she also asked the elves to prepare their own meals.

"Of course it's terrifying. They're not from the Ministry of Magic, they're just eating and drinking for free. If someone from the Ministry of Magic comes here, they can only finish their work in one day..."

Andrew put the file away. "They are real experts. All the big names in the field of Herbology in the British wizarding world are here. The professor is so happy... Let's not talk about the outstanding students in Hufflepuff College. The other students who are good at Herbology have been skipping classes and staying in the greenhouse these days..."

"No, if I hadn't been worried about committing to this course, I would have skipped it..."

Percy nodded frantically, "Professor Snape goes there every now and then, and he really came up with something good this time."

"That's right. I guess the prices of potion ingredients will be interesting in the future."

Andrew nodded in agreement—after this beginning, the growth of herbology was almost beyond his comprehension.

"The price of potion ingredients?"

Percy was stunned for a moment, then his eyes cleared, "Ah, yes, that's right, that's it!"

He stood up almost immediately, "Andrew, how did you come up with this idea? This kind of thing, this kind of thing is simply, too crazy!"

"You'll know once you think about it. By the way, if you want to stock up, I suggest you get potions that require a lot of high-end herbs and a small amount of high-end animal ingredients. I guess the animal ingredients can increase the price a lot - of course, there are risks, but not big."

"Let me think about it. Yes, that one. That one will definitely work..."

Percy, a top student in Potions, had his brain working rapidly. "If nothing goes wrong - would you like some, Andrew?"

"I won't do it. You'll graduate next year and be working as a prefect, so it's reasonable and legal for me to do it myself. It would be against the rules... You should also be careful. Don't borrow money to do it, or the Ministry of Magic will find out. Although it's completely legal, it will have a bad impact." Andrew shook his head - if it's less, it's not worth it, and if it's more, he would be considered as trading in inside information. Just tell Percy a word to let him earn some pocket money.

"Okay, I know my limits."

-

With so many herbology experts gathered at Hogwarts, it was naturally impossible to suppress the news, especially when there were so many listeners - probably less than three days after Andrew and Percy talked about it, the fact that Hogwarts had developed a rapid planting technology was directly exposed.

Then, more accurate news emerged - large-scale production of rare herbs across the seasons had become possible, and actual greenhouses had been built.

The prices of animal materials began to rise wildly, especially the one Percy bet on - after a resale, Percy probably got more than 300 Galleons.

"It's really... a terrifying speed..."

Percy looked at Andrew and didn't say anything stupid like splitting the money. "I have all the notes. You can use whatever you want..."

"Then I'm welcome."

Andrew nodded. "I want both spells and potions. I won't return the Defense Against the Dark Arts..."

"Okay, I'll bring it to you tomorrow..."

Percy nodded seriously, but still a little scared, "The price changes every day... It's going up like crazy..."

"That's normal. I guess a lot of people in our academy are involved. If I didn't know too much information, I would have participated... I'm different from you, Percy. I'm involved too much..."

If the students hadn't been involved in the greenhouse affairs, he wouldn't have been able to mention Percy's raw materials.

-

But herbalism is good at creating surprises - around mid-March, good news came from the laboratory.

A new lamp has been developed that has a high damage rate and high energy consumption, but has greatly improved performance. It is said to be modeled after a Muggle halogen lamp.

But this time it is no longer a full-scale imitation.

The filling gas has been modified by Transfiguration - the performance is terribly high. The most important thing is that because only Transfiguration is used, even if the damage rate is high, it can still be easily repaired with a repair spell until it is scrapped after many times.

"It's starting to become magical - a magic item that's even more magical than a magic lamp..."

"Although there are still some problems with production due to Transfiguration, but... the pressure is not too great... because I can use the repair spell, so the price can be higher..."

This was already a fairly stable magical transformation - as far as Andrew knew, LED lamps that could be used properly had not even appeared on the market. In other words, if the magic world developed normally, alchemical progress in the field of lamps would open up entirely new avenues.

"There is still a problem. Electricity is always a bottleneck..."

"Damn it, why are the wires restricted? Even if there is new energy without wires, how can we lay them out? We can't just turn on the lights one by one like in the library..."

"Channel...energy channel, this question is really..."

'Hmm? Passage?'

Andrew narrowed his eyes - speaking of energy channels, it seems to be real...

Yes, that's it!
Floo Network!
