Chapter 383 On-site Teaching
"I thought it would be difficult, Albus."

Professor Snape looked at the thing in his hand with an increasingly disgusted expression, "It turns out to be just a mixture that can be cleared up with the simplest Scapin Apparition Charm?"

'What is this spell?'

Andrew was a little confused - he had never heard of this spell, but its effect was really useful. With this dark water, who could analyze it clearly in such a short time without using any instruments?

Not only Andrew was confused, but also Professor McGonagall and Dumbledore who were present at the same time.

"The whole solution has no magical protection, Tyler?"

Professor McGonagall asked bluntly.

"No, Professor."

It's just an experiment to catalyze the hydrolysis of cellulose. Although some magic was used in the middle, the final reaction was a normal reaction - it would be fine if you just did some preparatory protection yourself, but why would you need magic protection when giving the potion?

Andrew's reaction earned Professor McGonagall a serious look. "You mean, the Transfiguration you performed on the glass basin to make it so solid did not have any confidentiality or interference effects, but was just to make it a little more solid?"

"In theory, yes. It is just used as a container. It looks more intuitive. Also, I have only completed some steps once. I am not sure if they are dangerous, so it is made more sturdy."

"Repeat it again, Andrew," Dumbledore said, the smile on his face fixed as if by some magic, "demonstrate it again."

"I need some more wood, Professor. I need to go back to the lab."

There is naturally nothing wrong with Andrew.

"Any kind of wood will do?"

"Yes, any wood will do. Grass is also fine in theory, but I always use wood for my experiments. If I change the material, I will need to make some adjustments."

"Jim," Dumbledore began, calling to the house-elf in Professor McGonagall's office, "bring some wood from the kitchen."

Professor Snape stood aside, looked at Professor McGonagall who looked quite serious and Dumbledore who looked happy, and finally said nothing and waited silently.

Soon, the elf brought a large pile of wood. Andrew picked and chose, found a few suitable ones, and then started the old routine - he didn't even separate out new enzymes, but directly used the last one, and completed the preliminary experiment again based on his own feeling.

"Where's the balance? Where's the dosage? Where's the protection of the access process?"

After Andrew completed the entire experiment using the process I had thought of, Professor Snape couldn't help but say, "You've completely thrown away the basics of Potions, Taylor!"

"I would like to, Professor, but I don't have a standard procedure - under the effect of the Vanishing Spell, who can balance the reaction formula without about half a year of exploration!"

But Professor Snape's reaction was surprisingly fast. He realized something was wrong while staring at Andrew. "Wait a minute, Albus, the basin of water I just tested..."

His gaze shifted to the basin of water that was still reacting - his voice was no longer as low and slow as before, "Are you kidding me, Albus, how is it possible, how is it possible?"

"Just like the results of your own tests, Severus, the facts are here."

Dumbledore stared at the basin of dirty-looking water. "You should know what it means, right?"

"Food. Almost endless food." He answered without hesitation. As the master of Potions, he was one of the people in Hogwarts who knew the specific ingredients of food best.

He was also the person in the entire Hogwarts who understood best what it felt like to be hungry - although he was of mixed blood, he had lived a life of hunger as a child, and both clothing and food were extremely scarce.

"Not yet," Dumbledore said seriously, "How is your spell study going, Andrew?"

"I started to learn the fifth grade part, and also mastered the non-living summoning spell "Clear Water Like a Spring" which is related to Transfiguration."

Andrew responded quickly. Although he didn't know what Dumbledore was doing, he was quite cooperative.

"Very good, I'll ask Pomona to come over."

Dumbledore nodded. "It will be ready soon. Don't worry."

Professor Sprout?

What is this going to do?
But he soon ran out of time to think about it - because both Professor McGonagall and Professor Snape were interested in the enzyme in his hand. They each took one-fifth of it and began to use Transfiguration to perceive it.

The professor even started asking questions about the extracted parts bit by bit after feeling it - just when Andrew was trying to explain the professional terms in it, Dumbledore had already arrived with Professor Sprout.

Also arriving was Professor McGonagall's elf, Jim, who brought a large basin of runny batter.

"I will tell you slowly, Pomona," Dumbledore was obviously anxious, "but before I explain, you have to teach Andrew how to use food magic."

Professor Sprout was still a little out of breath at the moment, but when he heard what Dumbledore said, the good professor's eyes widened, "Albus, this is not April Fool's Day, you said there was something extremely important that needed my help!"

"This is the most important thing at the moment, Pomona," Dumbledore said with a serious expression, "It doesn't require all the magic, just turning the batter into bread, or even pancakes, as long as it's edible. It would be even better if the toxicity of the ingredients could be removed."

what?
Andrew probably understood it, but did he learn it on the spot?
"Okay, Albus, but I really need an explanation," Professor Sprout shook his head and looked at Andrew, "But the first thing a novice makes is probably not much better than Hagrid's rock cake."

"It's okay, just take shape. I'll explain it to you when Andrew practices casting spells."

Dumbledore nodded.

Then, no one spoke except Professor Sprout. Even Professor Snape stood there quietly, watching Professor Sprout teach.

Andrew, who was being watched by two principals and three professors at the same time, began to experience the most stressful magic learning experience since he entered the wizarding world.

Fortunately, what he needed to learn was not a series of food magic, and Professor Sprout had no intention of teaching him from scratch.

With his solid foundation in spells, he began to understand the magic of pancake making little by little - but he definitely didn't want to go through this kind of one-on-one teaching again.

In less than half an hour, he felt that he had mastered the spell.

"Wait a moment, don't do the experiment yet. When I come back, I have to call Filius and ask him to bring some things over."

Dumbledore looked at Professor Sprout, who looked unhappy, and said happily, "Don't worry, Pomona, it will be fine soon!"
