This is what Ravenclaw looks like.

"Wires are an absolute no-no..."

"That's the problem - we get lazy on the light fixtures, and then we can't get lazy on the rest..."

The more magical protection, the less Muggle technology.

While Andrew was secretly hiding himself, a group of prospective graduates in the laboratory were already losing their hair.

The accumulated protection system of Hogwarts made electricity, the basis of Muggle technology, ineffective - probably because electricity was considered to be some kind of magic and thus lost its effectiveness.

The problem lies here - among Muggle technology, incandescent lamps are the lowest level. Because they have been converted twice, they can be implemented after jumping over them. Directly changing the current heating to magic, the rest is basically the same. There is no possibility of duplication anymore.

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

"It's almost impossible... you can't even do Transfiguration. What we are involved in, no, there is no Transfiguration course on filaments in the entire Hogwarts, right?"

"What else do we need to do?"

"Lamps that are more suitable for planting... The tungsten filament cannot be changed. We can't tamper with the glass... and that has nothing to do with it..."

"How about gas? Just the filling in the lamp?"

"It seems that there is a clue... and in the information I read some time ago, Muggles also used this method..."

Although it feels a bit...well, it seems to be plagiarism, but there is nothing wrong with continuing to explore on the path of previous explorations.

"It's really scary..."

In the office, Percy was still feeling emotional - in theory, Hogwarts is a pure school and does not accept entry from unrelated people for a long time.

However, after the visit of those herbal masters, the definition of irrelevant people seemed to have been completely revised.

The school board didn't say anything. As for Professor McGonagall, she didn't even seem to mind the trouble. She just ran to the greenhouse for a long time and specifically asked the elves to turn on the stove.

"Of course it's scary. It's not like people from the Ministry of Magic are just messing around - if you want people from the Ministry of Magic to come, you can't finish the business in one day..."

Andrew put the documents away, "Those are real experts - all the famous people in the field of herbal medicine in the British wizarding world are here. It's too late for the professor to be happy... Not to mention the outstanding students of Hufflepuff House, the rest of the herbal medicine Students who are good at studying are skipping classes and squatting in the greenhouse these days..."

"No, if I hadn't been worried about joining this course, I would have skipped class..."

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

"That's right. I guess the prices of potion raw materials will be very interesting next."

Andrew nodded in agreement - after having a beginning, he could hardly understand the growth of herbalism.

"The price of the ingredients for the magic potion?"

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

He stood up almost immediately, "Andrew, how did you think of it? This kind of thing, this kind of thing is simply crazy!"

"Just think about it. By the way, if you want to stock up, I suggest you buy those potions that require a large amount of high-end herbs and a small amount of high-end animal raw materials. It is estimated that the price of animal raw materials will increase a lot - of course, there are Risk, but not big.”

"Let me think about it, yes, it's that one, that one can definitely be..."

Percy, a top student in Potions, was thinking rapidly, "If nothing goes wrong - do you want some too, Andrew?"

"I won't do it. You will graduate next year and work as a prefect. It's reasonable and reasonable. It would be too illegal for me to do it myself... You should also be careful, don't borrow money to do it, or you may be found out by the Ministry of Magic. Although it is completely compliant, but The impact is not good.”

Andrew shook his head - at least it wasn't worth it, at most he was just buying and selling inside information, just tell Percy and let him make some pocket money.

"Okay, I know what's appropriate."

——

With so many herbology experts gathered at Hogwarts, the news cannot be suppressed, especially when there are a lot of observers - probably in less than three days after Andrew and Percy said that Hogwarts The rapid planting technology was directly exposed.

Later, more accurate news emerged - it was possible to produce rare herbs on a large scale across seasons, and actual greenhouses were built.

The price of animal-based materials began to rise crazily, especially the one that Percy had bet on - in a sudden change, Percy got probably more than three hundred galleons.

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

Percy looked at Andrew and didn't say anything stupid like penny, "I have a full set of notes, you can use it whatever you want..."

"Then I'm welcome."

Andrew nodded, "I want the spells and potions, but I won't return them to Defense Against the Dark Arts..."

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

Percy nodded seriously, but still a little scared, "It's literally a price a day...it's gone crazy..."

"It's normal. I guess many people from our college are involved. If I didn't know too much information, I would be involved... I'm different from you, Percy. I'm involved in too many things..."

If the students hadn't been involved in the greenhouse, he wouldn't have mentioned anything about Percy's raw materials.

But herbalism is good at delivering surprises—and around mid-March, good news came from the lab.

A new lamp with high damage rate and high energy consumption but great effect improvement has been developed. It is said to be a product 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 terrifyingly high. The most important thing is that because only Transfiguration is used, even if the damage rate is a little high, it can still be easily repaired with a repair spell until it is scrapped after many times.

‘It has begun to become magical - a magic prop that is more magical than a magic lamp...’

‘Although there are still problems with production due to Transfiguration, but... there is not much pressure... because the repair spell can be used, the price can be higher...’

This is already a fairly stable magic transformation - as far as Andrew knows, LED lamps that can be used regularly have not even appeared on the market. In other words, if the magic world develops normally, the alchemy progress in the field of lamps will develop a new path.

‘There is still a problem, the electricity is always stuck…’

‘Damn it, why are the wires restricted? Without wires, how can we lay out new energy? We can’t just turn on the lights one by one like in the library…’

‘Channel…Energy channel, this question is really…’

‘Hmm? Channel? ’

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

Yes, that’s it!

Floo Network!
