Chapter 504: The surprise attack before the meeting of the four schools
Although the meeting between the principals of the four schools was in October, the timing was very interesting - the end of October, October 30th.

There is no way, because Hogwarts is the organizer, and the other schools must conduct the first selection at home - we can't send all the students of the right age here, then can't we do the normal teaching work?

This meeting, which was delayed until the end of October, left Andrew enough time to make a final sprint in dream modification.

Professors are not robots and cannot be busy with this and that. The official start of the Triwizard Tournament will take up a lot of the professors' energy and make them lose interest in continuing their research.

Although the things being researched are indeed very cruel and closely related to the Astronomy Tower, there is still one advantage - Andrew no longer has to worry about being the only one to be hanged.

After the three deans tested the constructed dreams, they gladly accepted the task of creating a container to hold the dreams. As for Andrew, he was asked by his dean to continue his research on extending dream time and improving dream construction to the limit.

As for the legend - that is another matter. The three professors each obtained first-hand information about constructing dreams from him, and then advised him not to indulge in short-term happiness, but to study magic in depth, and entertainment things can be put aside for the time being.

Such an outrageous statement made Andrew roll his eyes afterwards.

Who is so obsessed with making up rumors about Dumbledore?
He was just an ordinary student who studied dreams in the hope of saving people. At most, he had some entertainment ideas mixed in. What did a legend have to do with him?

Unfortunately, he had no choice but to complain helplessly behind her back and continue to focus on improving his dreams.

After no longer having to worry about the problem of reserve media, his dream compilation technology developed rapidly with the help of Transfiguration - clarity, environment construction, and even the duration of dreams were all improving rapidly.

Around the end of mid-October, he finally reached the limit of the original daydream spell - he increased the dream duration to thirty minutes. At the same time, the latest dream had bid farewell to the mosaic. Although from a distance it still looked like an empty, unfillable blank, but if you zoomed in, it looked like an old, unclear memory.

At this time, good news came from the dean and professors - the new thing named Dream Ball was broken through by Professor Snape.

He conceived a potion based on the Pensieve, and then combined it with the technology of making the prophecy ball, and successfully created an existence that can accommodate dreams for about thirty minutes.

Although the price is still very high, this thing can be used multiple times, it's just more difficult to make.

And it was not only Professor Snape who had a breakthrough. Professor Sprout was even more exaggerated. She used her knowledge of herbal medicine, which Andrew had not mastered at all, and created a plant that could devour dreams. Although its growth cycle is a bit longer at present, the fruit produced by this thing is actually a disposable dream!

Anyway, the actions of the two professors directly shocked Andrew - he had not experienced the latter due to the problem of growth time, but the former was undoubtedly usable. He only needed to stick the thing on his forehead when dreaming, and this thing would record the dream, and then reproduce it by consuming potions!
As for Professor Flitwick, although there has been no results yet because Professor Snape made the dream ball too late, the dream projection spell based on projection magic has been developed by more than half!

In the dean's office, the four of them briefly checked their accounts and found that by putting them together, they could roughly complete the original concept - one-time and multiple private dreams, as well as public dreams that could even be projected on the screen, all had a rough outline.

"You're slow, Pomona."

Professor Flitwick said with a smile on his face, "You have to hurry up. I have an idea - how about we give them a surprise before the Triwizard Tournament?"

...

Do you mean the four of us hanging from the astronomy tower?

Andrew suddenly had a bad feeling, but unfortunately, the dean stepped on the accelerator and didn't let anyone get out of the car.

"I found a lot of precious plants to barely complete the swallowing and reproduction of the dream. Plants need time to grow, Filius." Professor Sprout shook his head, "But I am very sure that its fruit is what we need."

"Pomona, your plant cultivation skills are as reassuring as ever," Professor Flitwick shook his head. "I'm just worried that I don't have time to develop dream projection technology for it. Severus, do you have any other requirements for projection technology?"

"I'm fine with that. My part is done—I want the latest dreamweaving, Taylor."

Professor Snape looked nonchalant.

"Well, I'll demonstrate it later."

Andrew nodded - this thing would be released to the public later anyway, and he was still not satisfied with the results so far, so he planned to continue improving it.

Whether it is the dream conversion of memory or the transfer effect of the induced forgetfulness spell, they are all subsequent research topics. He has not forgotten his original intention, which is to save Professor Lockhart's victims from amnesia.

That was the most troublesome thing afterwards - fortunately, with the help of the professors, the bait had been successfully made and the next step had been found.

As for how the magical world develops, whether it will be a teaching dream or some other messy dream, that is another matter. Anyway, this thing is a very good supplement to the magical world which lacks entertainment.

'It's just that the requirements are a bit difficult... You need to have a certain foundation in Transfiguration and Charms to create a good dream, otherwise you can only stare blankly. This doesn't matter, anyway, it's around the average level of normal graduates, so it's not a big problem...'

The meeting ended with him demonstrating his latest dream-making technique - but this time the medium was the new Dream Ball.

Andrew completed a part of the legendary production with trepidation, from the sorting to the class...

"Very good, this effect is worth watching!"

Professor Flitwick praised generously, "Of course, Taylor, you have to continue to improve. I think you have great potential in perfecting the spell."

"Okay, I'll do my best, Professor."

Andrew nodded - he had reduced the amount of herbs he burned, and had basically spent all his free time on them during this period.

"That's good. Don't get too obsessed with creating entertaining dreams. Although a legend is fun to watch, you still need to pay attention to perfecting and learning the spells."

"I will perfect a legendary story after I master the art of dream compilation. You don't have to worry about not having any results to show."

The dean instructed, and the other two professors nodded subtly.

...

"Who cares? It's over! Let's go to the Astronomy Tower together..."
