Finally, Professor Flitwick explained to Darren and Hermione the magic of words on the "Living Point Map", and thanks to Darren's efforts, he was able to obtain the "Stretch Without a Trace", after all, he would stay at Hogwarts during the holidays, and maybe something would go wrong with the tent. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Under Professor Flitwick's personal guidance, Darren mastered it as quickly as possible, and after two weeks, he was able to pour a pot of tea into a teacup so that no one would hit his head with boiling water in the future......

"Tsk, it seems that our Mr. Sean can't guarantee that the perfect potion will be prepared every time," looking at the yellow-green paste in Darren's cauldron, a smile appeared on Snape's gloomy face, "I guess you must not have listened well, otherwise you wouldn't have failed, Gryffindor deducted 5 points, stay in class after class, and do the experiment again." ”

Snape's voice suddenly rang out in the Potions classroom, causing the classroom to fall silent, followed by a burst of "whispers", especially on the Slytherin side, where Malfoy laughed heartily with his friends Crabbe and Goyle.

The "know-it-all" in the potions class, Darren would actually boil the potion, this is incredible, even Hermione cast a surprised look, Darren peeked at her crucible, although there was still some foam, but obviously not far from completion, clear and colorless.

Maybe it was because he spent too much energy on spells, and as a result, in Potions class, Darren made a mistake for the first time, and the potions he brewed didn't work!

"What's going on?" Ron next to him looked at Darren with a shocked face, completely oblivious to Snape's words.

In order to minimize the chance of Snape deducting points from Gryffindor, Darren did not team up with Hermione in this semester's Potions class, and if the two of them were separated, they would at least save two unlucky eggs, but today Darren obviously didn't succeed either, and Snape found an opportunity to stimulate him.

"Impossible! I followed the procedure on the blackboard exactly, Ron, did you check my steps according to the record? ”

"Oh, I'm watching."

“？！ You're just watching me do it, are you? ”

“……”

Well, it seems that Darren has found the reason, but he looks at the board book on the blackboard and tries to recall what he did just now, it seems that there is nothing wrong with it? So why did the potion that was supposed to be clear and colorless turn into a yellowish-green sticky mass?

Darren began to quickly recall the steps of the operation just now, "Clean-Pick-Weigh-Crush-Mix-Stir," Darren's gaze rested on the stone mortar that Ron used to crush the fangs and lizard bones, he took it and shook it, and there was a fang's tip among the tiny bone fragments inside.

As the course progressed, the steps of potion operation became more and more complicated, and it was impossible for a single person to complete the class alone, which Darren used to do by himself.

That night, a new article was added to the "Potions Operation Safety Regulations" posted at the entrance of the Potions classroom, carefully cleaning the experimental equipment to avoid mutual contamination of the potion materials.

There is also a rule, after weighing and crushing, the material should be weighed again to reduce the error.

At this time, Darren also knew that it was no wonder that in the past in the Potions class, other people's yields were surprisingly low, and they didn't have good operating habits, so they threw the ingredients in and cooked them like porridge, even if the operation order was correct, it was normal for things to not come out, after all, this was not porridge......

By the way, Darren can still find a chance to chat with Professor Snape, who usually has a dead face and can't find anyone.

"Professor, when you first took Potions class, you said, 'You can teach how to increase prestige, brew glory, and even stop death,' can you stop death with potions?"

Hearing Darren's question, Snape looked up from the book in front of her and stared at Darren, "Mr. Shaun, it seems that you have a really good memory, and you're lucky, it's important for studying potions," he paused and looked at Darren with those black eyes, "But sometimes, your memory seems to be terrible, didn't you venture with Mr. Potter into the fourth-floor hallway of the school at the end of last semester, if I'm not mistaken, you must know what's there." ”

Snape leaned down and let his hair fall in front of Darren's eyes, "The Philosopher's Stone, the last known Philosopher's Stone in the wizarding world at the moment, has gone through its own life with its maker, a life of six hundred and sixty-seven years old, isn't that enough?" ”

"If I knew......" Although the voice was small, Darren still heard a trace of words coming from Snape's mouth, and it seemed that he was a little unwilling to have the Philosopher's Stone destroyed.

"Oh, I know, but it's quite difficult to make a philosopher's stone, isn't it, otherwise there wouldn't be just one, I mean an ordinary potion that can make people live for an extra year or two hundred years."

After listening to Darren's words, Snape's face finally showed a strange expression, "Ordinary ...... One or two hundred years...... What do you think potions are? Is it really the ridiculous Muggle books that write about colorful bubbling liquids, something that can be infinitely powerful when drunk? No, Potions is a technique, it's sophisticated and rigorous, I originally thought that you would come from the Muggle world like everyone else, but in the back of my mind, you were still a ......"

For a moment, there was a hint of trance on Snape's face, and he stopped and did not continue.

"But I'm talking about the wizarding world, I've seen it with my own eyes." Darren said in an unconvinced tone.

"Are you referring to Professor Dumbledore? A wizard of his level, the magic itself will maintain the operation of the body, and he will live for a long time before his magic power declines, but that has nothing to do with potions, in fact, if there are no accidents, most wizards can live for a long time, at least much longer than Muggles, and besides, it seems too early to care about this issue for your age. ”

"Oh, there are some things that are important in the Muggle world, like pet hospitals and the like, do animals live long because of magic?"

“…… I think you should ask Keitel, the teacher of the Conservation of Magical Creatures class, this question. Professor Bourne, he is an authority on this aspect. ”

"It's not a magical creature, it's an ordinary animal, and they live longer because of magic at Hogwarts, or in wizarding families?"

"This is impossible, ordinary animals are ordinary animals, unless a spell is cast on them, there is no magic that will act on them."

"That's strange, how can it live that long......"
