Chapter 559: Let’s Set the Tone First

"I have heard and seen many claims, and I have also seen many wizards who stick to their claims - they dare to defend their claims with everything, including their own lives."

Andrew looked at the wizards present and said something they had never expected.

"But I've never been good at this. It seems I never had any talent for it," Andrew nodded affirmatively. "Fortunately, I have some talents in other areas, so I don't have to rack my brains over this annoying problem."

"No matter what the idea is, wizards always need potions, food, clothes and some activities to entertain themselves physically and mentally. No matter what the idea is, it will always make wizards better, both materially and spiritually."

He glanced at the students from Durmstrang and Kodostoriz. Just after they came in for a while, the wizards from the two families had some unpleasantness - it was obvious that the school's cooperation was the school's, and the students' were the students'.

But debate is fruitless. Prejudice in people's hearts is as big as a mountain. Facts are the most convincing.

Although he was able to use magic to briefly convince the students present, it was of no avail.

"So, I hope our discussion will also be about how to make life better. After all, I can't help others with ideas - ah, black magic is not good either, I'm not good at that."

Andrew said this without any modesty, but the students present did not object to it.

After publicly obtaining the status of referee, he truly has the power to judge students, and there is no room for any dissatisfaction.

"That's it, let's start with seventh grade."

Andrew went back and sat down, and began to move the chessboard - he took a shortcut and used rules similar to those of a deformed chessboard to expand the room, making half a day's preparation possible.

The seventh grade student closest to him almost couldn't wait to stand up - it would be impossible for a student who was not an exhibitionist to squeeze into this position.

"That's the single-person dream conversion device that we just made. Although the size problem hasn't been solved, we can still show the idea."

Andrew loudly reminded the other party to put his hand up - not everyone is good at all languages, but the pictures are common most of the time.

"Thank you, Mr. Taylor, but I don't really need it," said the student of Kodos Doritz, whose English was surprisingly good. "What do you think will be the main force for the next advancement of the wizarding world?"

"This is not a press interview, sir," Andrew shook his head. "I think we are here to see the fantastic future magical world, not to listen to me rambling on. But I can still give you an answer."

He straightened up. "I think it's the materials, the materials synthesized by magic, whether they are made by mixing metals, cultivating magical creatures, or materials made by ritual magic, alchemy, etc., which must be the foundation for the entire magical world."

"But why, sir?"

The other party looked at Andrew in surprise. It was obvious that this answer was beyond his thinking.

"Because we need more magic in our lives," Andrew said affirmatively, "Traditional magic materials are very useful. Yes, I agree very much. The carefully selected wand materials, the wood on the flying broom that has been cast with magic inch by inch, the finely woven wizard robes, the dragon leather gloves that have been cast with magic many times... yes, they are excellent, so excellent that there is no better substitute until now, but this is not right."

"Herbalists repeatedly select herbs to make their yields more abundant and their medicinal properties more and more stable. Alchemy factories repeatedly adjust their alchemical fertilizers. Potions repeatedly modify their formulas, but other basic materials rarely change..."

Andrew spread his hands. "I don't know if I'm too radical, but there is no doubt that it makes sense to try in this regard." He noticed that many senior students were eager to try over there - or rather, they had already spoken, but were blocked by Andrew's magic.

'interesting…'

He waved his wand, freeing all the seventh graders.

"I'm sorry, Mr. Taylor," a girl from Beauxbatons was the first to notice this and took the initiative, "You mean, we need to find new materials for the wand as well?"

"I'm not sure," Andrew shook his head. "I have a very good friend who studies magic history named Hughes. He has taught me the history of the development of magic wands. In fact, the current version of the magic wand is the most perfect ratio determined after too many experiments. They searched almost all the materials in the world to explore the most powerful ratio, and then determined the current version of the magic wand."

He nodded affirmatively. "But I don't really believe in perfection. Maybe we can try something that doesn't exist in this magical world."

"Something you don't have?"

Not only the girl was surprised, but also a bunch of seniors.

"Yes, there is nothing. I think students who have taken magical creatures, especially those in Beauxbatons, should all know that those magical biologists are best at creating new and dangerous things."

Many students burst out laughing, especially those at Hogwarts.

Hagrid's blasting-tailed skrewt made the students suffer this year.

"Herbalism has it too, except that it's more dangerous. The other things are just more expensive."

Andrew shook his head - the stuff in the textbooks was fine, but what happened in private was really weird.

Just think about it, there are so many things that can be done with just oranges and grapefruits, and that’s not even including plants from the magical world! Because of the durability of herbs, this subject, which has the most contact with the Muggle world, has come up with a lot of new things.

"In fact, even air is a great material, at least in terms of transfiguration," Andrew turned the subject to the area he was most familiar with.

"In fact, the air we commonly see is divided into various components, but they are all named uniformly in alchemy. However, this does not affect our attempts to change the composition of air to make it a substance of another nature."

Although the students were asked to present themselves, Andrew still stood at the top and put his hand on the huge dream bead. "The following will be a bit boring. Please pay attention to some snacks."

The dream bead was instantly lit up just as he tested it, and a huge curtain of light was erected.

'It's my show, but it's not impossible.'

He looked around and confirmed that most of the senior students were listening attentively to the lecture, then he presented an experiment he had done some time ago.
