The Day of the Duel at Hogwarts.

Chapter 211 The first phase of research is over (seeking subscription, monthly ticket)

Snape suddenly mentioned the werewolf in the last chapter, which immediately caused a commotion among the little wizards, but with Snape deducting points from Harry and Hermione just now, the commotion belongs to the commotion, and the little wizards are not Dare to say more.

After one class, everyone has a preliminary understanding of werewolves.

In class, Snape repeatedly emphasized the content on how to identify werewolves. Most of the people were a little impatient, but Sean noticed that the expression of a young wizard with a sharp mind like Hermione had already begun to change. It became ugly. Obviously, under Snape's many hints, she noticed something more or less.

When get out of class was over, Hermione didn't even go with Harry and Ron. She left the classroom immediately and went directly to the library. She wanted to check some books about werewolves.

Sean and Blaise walked out of the Defense Against the Dark Arts classroom, and the two separated when they reached the first floor. Blaise and Andy made an appointment to watch Quidditch training, and Sean followed Snape's footsteps , came to his office.

Walking into Snape's office, Sean closed the door and said, "Professor, how about my third material substitute, is it okay?"

"I did an experiment before class, and there are some problems."

Hearing this, Xiao En frowned. According to his calculations, there should be no problem with the substitution of the third material, but as the saying goes, true knowledge is obtained through experiments, and it is not necessarily possible to calculate all the changes in the calculation. There are likely to be some omissions.

So when Sean heard Snape's words, he immediately asked, "Professor, what's the problem?"

"If it's just pure medicinal effect, there is not much difference between your substitute and the original material. Even if there is a very slight difference in medicinal effect, it is still negligible. But there is a problem here. The third In the substitute potion of the first material, one material conflicts with one of the materials in the first substitute potion. When the potion is brewed, the two materials will repel, causing the potion to explode. Failure, this kind of conflict cannot be reconciled, and we can only choose an alternative, either replace the first or the third."

When researching alternative materials, Sean knew that one day he would encounter conflicts with alternative potions, but he did not expect that he would encounter this problem so soon, and this was only the first stage of research !
"I'll go back and think about it, and replace them with materials with more peaceful medicinal effects as much as possible to reduce the possibility of future conflicts."

"I will also pay attention here, go."

Holding Snape's experimental materials, Sean went straight back to the bedroom, and went to the library with the materials he had accumulated before.

Sean didn't use a quill this time. He used the pencil he brought when he started school. In order to make calculations easier and faster, Sean brought a lot of pencils and draft paper.

It's a pity that electronic products cannot be used in Hogwarts, otherwise a computer or calculator can be used to calculate faster.

I don't know how long it took before Mrs. Pince came to Sean. She looked at the calculation papers in Sean's hand, and then at the five or six spirit recovery potions on the table next to him. Woz's students were not too cold, so she couldn't help but slow down.

"It's time, I'm closing the library."

Mrs. Pince's words made Sean stunned for a moment. He came back to his senses, looked at the darkened sky outside the window, and said in a daze, "It's dark? So soon..."

"You go back now, and you still have time to find the house-elf to prepare some food for you. You haven't eaten tonight, have you?"

Nodding, Sean, who came back to his senses, said to Mrs. Pince while packing his things: "It's true that I haven't eaten. Thank you Mrs. Pince. I will pay attention when I go back."

"Well, don't forget your things, and don't forget to take away the trash."

"Yes, Mrs. Pince."

Sean packed his things quickly, but instead of going back to the Slytherin common room, he went directly to the kitchen to ask the house elves for some food and drink, and then went straight to the Room of Requirement with the things.

Sitting in the comfortable Response Room, Sean simply ate and drank something, and drank two potions, one was used to relieve physical fatigue, and the other was a spirit recovery potion.

After a short rest, after the effect of the potion took effect, Sean picked up the pen again and continued the unfinished calculations.

Early the next morning, Sean stood at the gate of Hogwarts Castle. Looking at the light rain outside, he reluctantly took out his wand, cast a waterproof spell on himself, and then summoned an umbrella from the tip of the wand , then walked out of Hogwarts Castle and came to the Quidditch pitch.

At this point, the game on the Quidditch pitch had already begun.

It can be seen that Gryffindor and Hufflepuff have already started fighting.

However, compared to the game between Gryffindor and Slytherin, the two sides were much more civilized, and many extreme behaviors did not appear.

Sean came to the Slytherin stands. Since there were no Slytherins on both sides of the match, not many people were willing to watch the match between Gryffindor and Hufflepuff in the rain.

To Sean's surprise, Malfoy and the others actually came, and he didn't know whether it was because they came to see Harry or the game.

After finding Blaise, Andy, and Jason, Sean walked over, yawned, and sat down on the seat on which Andy had cast a drying spell, put away the umbrella, and there was a barrier on the stands Canopy, no need for an umbrella.

Blaise looked at Sean, wanting to say something, but when he saw Sean, he was immediately startled by Sean.

"Sean, what did you do last night? Why are there so many dark circles under your eyes?"

Hearing Blaise's words, Andy also looked over. When he saw the dark circles on Sean's face, he was startled and said, "Sean, didn't you sleep last night? We looked for you this morning. There is no one in your room, we thought you went out first, but now it seems that you didn't sleep last night, did you?"

"Well, I found a place to do papers and data."

"How's the result?"

"It's done. One day and one night. When I came here, I just handed over the thesis to the dean. I just need to wait for the dean's notice. The research at this stage is considered to be over. I need to take a good rest for a while. , add some energy, the next stage of research will not be so easy."

As soon as Xiao En's words fell, exclamations suddenly sounded from the audience stage. Harry, who had rushed into the sky to track the Snitch just now, fell from mid-air, and accompanied by the falling Harry, a large number of soul-stirring The monster flew out of the dark clouds and rushed towards the students in the stands!
