Chapter 654: Andrew Disappears
"Another pile of homework, and before the Easter holidays...Merlin's beard!"

When the Transfiguration class was over, a group of fifth-grade students felt the air around them become a little looser and they were able to breathe.

Ron looked at the homework assigned by Professor McGonagall with a dazed look in his eyes.

It was normal that the debt he had incurred when he gave up Transfiguration and worked hard to learn spells had come to a head today - even with Hermione's help, he was still confused. Not to mention keeping up with Professor McGonagall's progress, even if he studied privately, it would be difficult for him to fully understand all the content of the fourth grade.

"But it has to be done, Ron."

Hermione reminded quietly, "If you can't keep up, I'm afraid there will be problems with your certificate. I borrowed the previous exam questions, and what you are reviewing now is not enough."

"Not enough, not enough—" Ron muttered, "But there are students who refuse to attend classes from the beginning...even for Charms. Professor Flitwick openly told me that Taylor has the ability to get full marks directly."

"It's not the first time I've heard of this," Harry came closer, his expression also somewhat distressed, "At least get the certificate. If you can't pass the OWLs exam, I'm afraid Professor McGonagall will kill you."

"I also want to break through the spell and be exempted from all the exams... Taylor hasn't been in class for two weeks, right?"

"Well, two weeks, I think. Not to mention classes, he's not even on time for meals. The Ravenclaw prefects haven't seen him much."

Harry said this with certainty - the other party was no longer in the same state as the students, and even did not do the office chores that he had been responsible for before, and was mysteriously missing all day long.

"But it's almost Easter break, he'll have to show up or something, but Ron, why do you care so much about Tyler?"

Harry looked at Ron with a puzzled look on his face.

Ron blushed a little - he was too embarrassed to say that in this busy fifth year, he had the mind to care about Chocolate Frog cards.

But it’s already been advertised, seven new cards, especially Harry even begged for a signed version…

"I'm just curious about his achievements in subjects other than Transfiguration, especially Charms. I still don't understand what Professor Flitwick meant when he said he would definitely get full marks."

Ron took a long time to come up with an excuse and finally succeeded in fooling the man.

"I'm curious, too," Hermione agreed, with a puzzled look in her eyes - she had also heard several professors say this, but unfortunately, no professor had ever said this to her so confidently.

Fortunately, I had been mentally prepared for this kind of thing since last year's competition - I had already lost the first place, so I could just focus on performing at my best.

"Long time no see, principals - the Easter holiday is here. As agreed, let's summarize our respective research directions and strive to improve our flight plan as soon as possible."

On the other side, Andrew, who had been absent from school for two weeks, was presiding over the meeting with dark circles under his eyes.

Giving up on reaching a consensus with Dumbledore, and with some hard work and the help of other students, he finally managed to come up with some theoretical models in time for the important Easter holiday.

At least for now, the theoretical strength of this material can withstand the third-level acceleration model.

Even though Andrew didn't fully understand the blueprints, he was able to replicate the general principle - he improved the alchemical oil, and then used Transfiguration to change its form, ensuring that this thing would explode when the Transfiguration was destroyed, and then blow up the flying device like a firecracker.

To put it simply, they used magic to imitate rockets, and then directly flew the aircraft up, and then used alchemical arrays similar to flying brooms to fine-tune the angle, mainly piling up materials and raw materials. The model that Dumbledore finally made was very, very outrageous - how to say it, it felt very much like a flying broom.

Reinforced raw materials, a huge cabin, and abundant food supply, in simple terms, it is a super-sized flying carriage that flies all the way.

This thing sounds very low-tech, just a large-scale Pegasus carriage, but judging by the finished product on display, the material of the weakest part exceeds that of existing technology by three times - there is no mechanism at all, and it all depends on Dumbledore's Transfiguration.

But this is not the most magical product.

He originally thought that Dumbledore's product was very magical, but after seeing the plans put forward by the other three schools, he was completely stunned.

The thing Durmstrang made shouldn't even be called a flying machine, but a lightning connection device - I don't know what the professors over there were thinking, but they turned an aviation thing into one that uses lightning for transmission.

Or maybe it shouldn't be called that - it should be called a lightning charger.

In short, the operating principle of that outrageous device is to charge energy with the help of the huge power of lightning, and then use the environment to directly pull the aircraft to obtain a huge initial velocity, and then eject the aircraft.

Andrew guessed that the other party must have used some background, war magic or magic to control the clouds, otherwise it would be unreasonable to use the earth and thunderclouds to create a huge catapult to obtain the initial velocity.

Because although it sounds outrageous, after Karkaroff's demonstration, even Andrew had to admit that there was nothing wrong with this thing except that it sounded weird.

As for Beauxbatons, it's even more amazing. I don't know how Madame Maxime mobilized the professors of the academy to cultivate a Pegasus that can stay in a vacuum for a long time, and it's not even the ultimate version.

"I said that everyone would analyze those aircraft in various ways..."

Andrew looked around at the various plans, his brain was a little overwhelmed - his plan was outrageous enough, relying entirely on Transfiguration to increase strength, but compared to the plans submitted by the principals, it seemed so technologically advanced, it could even be said to be the most replicable.

"How about we wait a little longer until the technology matures?"

Andrew looked around at the principals. "It's just that it's the end of the semester, so it's a bit rushed and can't be popularized. We can't be busy with Transfiguration and artificially building spaceships all day long, right?"

"Of course you can, but there is always a limit. Besides, isn't yours very mature, Professor Andrew?"

"But the key is that the materials are also handmade by Transfiguration, and I don't have that much time to make a complete one - let's study it during the summer vacation."

"Not that long?"

Principal Vladislav looked at Andrew in confusion - his plan was the least mature, so risky that it didn't even need to be perfected. Andrew even wanted to complain that the other party actually dared to pile up human lives!

"I have to study for my OWLs."

Andrew spread his hands.

But to his surprise, this outrageous excuse was unanimously recognized by the principals, who felt that he was doing the right thing - he should postpone it and prepare for the OWLs exams.
