The day of the duel at Hogwarts

"very good."

Snape looked at Harry, then at Hermione, and finally at Sean, and said: "The answer is very complete and accurate, I will give Slytherin five points.

Meanwhile, Potter!

Because you contradicted the teacher just now, I will deduct a point for Gryffindor. Ms. Granger just got up privately. I will also deduct a point for Gryffindor. I hope you can know next time. When you are teaching, don't be eager to show your meager knowledge. "

After speaking, Snape ignored Hermione who looked in disbelief, turned back to the podium, and began to teach everyone how to make scabies treatment potion.

Although he was already familiar with scabies treatment potions, Sean still did not slack off at all. He knew very well that Snape, as a rare potion master in the magical world, had his own understanding of many potions, although he did not know how to use them. Those who speak openly and honestly about their understanding of potions will reveal it more or less during class, and this is a huge gain for Sean.

Based on the textbook, combined with the notes of his grandfather Gavin, and some private work in Snape's courses, the three confirmed each other, and Sean eagerly absorbed all kinds of knowledge about potions.

Like Transfiguration, the second half of Potions class is also a time for practice.

They work in groups of two, and each group has a crucible and a set of ingredients for making a scabies treatment potion in front of them.

When it comes to brewing potions, Sean is only theoretically rich, but has never actually practiced it. His experience in cooking in his previous life can only allow him to control the crucible and the flame below more calmly. Other aspects require a little bit of practice. Just study.

Gollum...

The liquid in the crucible was slightly viscous. As Sean added the snake fang powder, the liquid quickly turned yellow-green. After a little stirring, the yellow-green liquid turned into clean emerald green.

The next step is to prepare the final material, the porcupine quills. You only need to add the final material and do a little processing to get the scabies treatment potion.

Blaise watched Sean handle the various materials and brew the potion step by step with great precision. He couldn't help but feel lucky that he and Sean had become friends. When everyone was making the potion just now, except Sean and Malfoy, , everyone was severely criticized by Snape, even Slytherin was no exception.

Among them, Harry Potter and Neville Longbottom were the hardest hit by criticism. The former was because Snape hated Harry, and the latter was because of simple mistakes.

Of course, apart from that, the one who was criticized the most was a Slytherin.

Millicent Burst!

Perhaps because he missed the mark when he asked the question just now, Snape had a very low opinion of Millicent, and he was mostly merciless when criticizing him. In addition, Millicent's talent in potions was mediocre. If he hadn't With Harry and Neville as targets, drawing most of Snape's firepower, Millicent might be sprayed into a sieve by Snape.

Carefully putting the porcupine quill into the crucible, Millicent held his breath, wanting to be the first to brew the potion to wash away his previous shame. However, he was too eager and ignored the effect of time on the potion. As a result, when he put the porcupine quills into the crucible, not only did he not wait for the previous materials to be completely integrated, he even ignored the need to temporarily move the crucible away from the flame.

So when Millicent put the porcupine quill into the crucible, the liquid in the crucible exploded as if it was put into a firecracker. The yellow-green, turbid and sticky liquid splashed outwards, most of it splashing out. When it hit Millicent's body, a large number of red and swollen fire boils instantly appeared on his body. From a distance, Millicent's body became bloated out of thin air. The pain on his body made Millicent cry out loudly, with tears and runny nose everywhere. Crossflow.

"idiot!"

Snape came to Millicent's side in three or two steps. With a wave of the wand in his hand, the liquid on the ground and table disappeared immediately. Then he looked at the injuries on Millicent's body and those of other people around him. One or two fire boils appeared, and he said directly to them: "Those who are injured, take Burst to the hospital above! As a Slytherin, he made such a low-level mistake in Potions class, it is unprecedented!"

Pansy and Goyle were also injured, and they immediately took Millicent out of the classroom. Pansy had an obvious look of disgust on her face.

Looking at the three Millicent people leaving, Snape turned to look at the others and said sternly: "Just now Millicent forgot to take the cauldron away from the fire when he put in the porcupine quills. This was to boil scabies. A big no-no with healing potions, I don’t want anyone else to make this mistake again!”

As soon as he said these words, Snape looked at Harry and said: "Potter, Millicent made a mistake and went to the hospital, but you are laughing there because you don't know unity. I will dunk for Gryffindor." one cent!"

"That's not fair. Harry wasn't laughing at Millicent. We were just..."

"Weasley! If you contradict the teacher, you will lose a point from Gryffindor!"

After being deducted two points in a row, Harry subconsciously wanted to defend himself, but Ron stopped him and whispered to Harry: "Stop talking, Snape is unreasonable, he seems to be discriminating against Gryffindor." If you do more, it will discriminate against you even more, so don’t be deducted more points.”

When Harry and Ron fell silent, Sean slightly stirred the potion in the crucible. As a white smoke rose, a pot of light green transparent potion appeared in the crucible. Sean carefully Pour the liquid into the container, and the moment the last drop of the potion falls into the container, Snape reaches out to pick up the container, sniffs it slightly, and finally shows a look of satisfaction on his face.

"Qualified scabies treatment potion, five points for Slytherin!"

Sean looked at Snape. He had gained a total of twenty points for this class, plus five points from the previous Transfiguration class. He had already recovered half of the fifty-point deduction. There was no Snape here. Sean himself didn't believe the result of Nap's preference.

As groups of little wizards completed their own potions, the Potions class finally came to an end.

After class, the little wizards left the classroom one after another, for fear of staying in the classroom for even a little longer, even Malfoy.

Sean was the last to leave.

Just as Sean was about to say goodbye to Snape, he heard the other person say: "Sean, I was partly responsible for why you were deducted fifty points before, although I didn't expect you to come to Slytherin at that time. …

Today's extra points are, firstly, because of your excellence, and secondly, because I have made some compensation for you. In the future, the extra points will not be so frequent, nor will they be so many every time, so you can take care of yourself. "

Having said this, Snape stopped saying anything. Instead, he took a step ahead of Sean and Blaise, dragging his black robe tumbling behind him, and quickly disappeared in front of Sean.
